The chance of spelling C-H-A-N-C-E in this order with a bag of 15 scrabble tiles containing three each of the letters A, C, E, H, and N can be calculated by multiplying the probabilities of picking each letter in the correct order.

we need to calculate the probability of picking the letter C. There are three C's in the bag and a total of 15 tiles, so the probability of picking C is 3/15 or 1/5.



Next, we need to calculate the probability of picking the letter H. After picking the first letter, there are 14 tiles left in the bag and three H's, so the probability of picking H is 3/14. We can calculate the probabilities of picking the letters A, N, C, and E in the correct order:


- Probability of picking A: 3/13
- Probability of picking N: 3/12 or 1/4
- Probability of picking C: 2/11
- Probability of picking E: 3/10
To find the overall probability of spelling C-H-A-N-C-E in this order, we multiply all of these probabilities together:
[tex](1/5) * (3/14) * (3/13) * (1/4) * (2/11) * (3/10) = 18/240240 = 3/40040[/tex]

Solve 19(1.12^x)=8(1.18^x). Show work.

Answers

Answer:

x≈12.6

Step-by-step explanation:

We have the equation:

19(1.12^x) = 8(1.18^x)

Divide both sides by 8:

19/8 (1.12^x) = (1.18^x)

Take the natural logarithm of both sides:

ln[19/8 (1.12^x)] = ln[1.18^x]

Using the properties of logarithms, we can simplify the left side:

ln(19/8) + ln(1.12^x) = x ln(1.18)

Substituting y = 1.12^x, we get:

ln(19/8) + ln(y) = ln(1.18) y

Now we can solve for y:

ln(y) = ln(1.18) y - ln(19/8)

Using a numerical method or a graphing calculator, we can find that y ≈ 10.584.

Substituting back to solve for x:

1.12^x ≈ 10.584

Taking the logarithm base 1.12 of both sides:

x ≈ ln(10.584)/ln(1.12)

x ≈ 12.6

Therefore, the solution to the equation is x ≈ 12.6.

find the cost in dollars of the operating a 100- w w lamp continuously for 1 week when the power utility rate is 16 cents/kwh c e n t s / k w h . express your answer using two significant figures.

Answers

Operating a 100-watt lamp for a week when the power utility rate is 16 cents/k

Wh can be calculated as follows:

Power of the lamp = 100 watts

Time of usage = 1 week = 7 days

Power utility rate = 16 cents/kWh

1 kW = 1000 watts

Power consumed by lamp = 100 watts

Total time of usage in hours = 7 days x 24 hours/day = 168 hours

Energy consumed = Power x Time= 100 watts x 168 hours= 16,800

watt-hours (Wh) = 16.8 kWh

Cost of operating the lamp = Energy consumed x Power utility rate= 16.8 kWh x 16 cents/k

Wh= 2.688 dollars= $2.7 (approx)

Therefore, the cost of operating a 100-watt lamp continuously for 1 week when the power utility rate is 16 cents/kWh is approximately $2.7 using two significant figures.

The value at the 60th percentile is 72°F. According to the given question.

What is whisker plot?

A whisker plot, also known as a box and whisker plot, is a graphical representation of a dataset that shows the distribution of values. It is often used to summarize and compare datasets, and to identify outliers or extreme values.

The plot is constructed using a rectangular box that represents the middle 50% of the data (the interquartile range or IQR). The box extends from the lower quartile (the value below which 25% of the data falls) to the upper quartile (the value below which 75% of the data falls). A line inside the box represents the median (the value below which 50% of the data falls).

Part A:

Here is a box and whisker plot representing the given data:

   |                   +                       |

75 -+                          +            |

   |                    |                       |

70 -+                |                       |

   |                    |                       |

65 -+-------------+-------------------+

   |  S  M  T  W |  T  F  S           |

The plot is divided into four sections: the lowest 25% of the data (the lower quartile), the next 25% of the data (the second quartile or median), the next 25% of the data (the third quartile), and the highest 25% of the data (the upper quartile). The box represents the middle 50% of the data, and the whiskers extend to the lowest and highest values that are not outliers.

Part B:

To determine which value is at a given percentile, we need to sort the data in ascending order and count how many values are less than or equal to the percentile we are interested in. Then we find the corresponding value in the sorted list.

For example, to find the value at the 60th percentile, we first calculate 60% of the total number of values, which is:

0.60 * 7 = 4.2

Since we cannot have a fraction of a value, we round up to the next integer, which is 5. This means that the value at the 60th percentile is the fifth value in the sorted list:

65, 66, 68, 70, 72, 74, 75

Therefore, the value at the 60th percentile is 72°F.

Answers

The length of one of the sides of the GIVE WAY sign, equilateral triangle is approximately 200.89cm.

What is an equilateral triangle?

An equilateral triangle in geometry is a triangle with equally long sides. The three angles opposing the three equal sides are equal in size because the three sides are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle. Equilateral triangles have the same area, perimeter, and height formula as other kinds of triangles.

Given that the triangle is an equilateral triangle, thus all sides are equal.

Let us suppose the sides = x.

The height of the equilateral triangle is given by:

height = (√3/2) x side length

Substituting the values:

110 = (√3/2) x (x)

x = 110 / (√3/2)

x ≈ 200.89cm

Hence, the length of one of the sides of the GIVE WAY sign is approximately 200.89cm.

The minimum number of people in the group should be 3.

In a group more than 1/2 are boys but there are less than 2/3 of the group.

Let the number of people in the group be x.

Therefore, the number of boys in the group is greater than 1/2 × x or x/2.

The number of people in the group is less than 2/3 × x or 2x/3.

As per the question, x > x/2 and x < 2x/3

multiply both sides by 2,

so we get:

2x > x and 2x < 4x/3.

Now, simplify the above equations as follows:

2x > x ⇒ x > 0 and

2x < 4x/3 ⇒ 6x < 4x ⇒ 0 < -2x ⇒ x < 0

Thus, it is not possible to have a group of 4 people as the number of people in the group is greater than 0.

Answers

The quantity of  shrink wrap that will be used to wrap ten game cubes is 540 square inches

To calculate the amount of shrink wrap needed to wrap ten game cubes, we need to first find the surface area of one game cube, and then multiply it by 10.

The surface area of a cube can be found by multiplying the length of one side by itself, and then multiplying that by 6 (since there are six faces on a cube). In this case, the length of one side is 3 inches, so the surface area of one cube is:

Surface area of one cube = 3 x 3 x 6 = 54 square inches

Answers

Norris living room table is a trapezoid shape with a bottom length of 613.5 inches, a top length of 11.3 inches, and a height of 12 inches.

To find the area of the tabletop, we need to calculate the average of the lengths of the top and bottom, and then multiply that by the height.

Average of lengths = (613.5 + 11.3)/2 = 312.4 inches

Area of table top = (312.4) x 12 = 3748.8 square inches

Since one can of paint covers 12 square inches, we can find the number of cans of paint needed by dividing the area of the table top by the coverage per can:

Number of cans of paint = 3748.8/12 = 312.4 cans

The measure of the angle x is 60 degrees and the sides of the triangle is 4√3 and 8.

What is sum of interior angles of triangle?

According to the triangle sum theorem, a triangle's internal angles can be added up to 180 degrees. The triangle sum theorem, often referred to as the angle sum theorem of the triangle, states that the total of the measures of a triangle's internal angles in a Euclidean space adds up to 180 degrees, whether the triangle is acute, obtuse, or right. The smallest polygon with three sides and three internal angles, one at each vertex, and bordered by two neighbouring sides is a triangle.

Given that, angle B = 30 degrees and angle m = 90 degrees.

The sum of all the angles of a triangle is 180 degrees.

Thus,

30 + 90 + angle x = 180

120 + angle x = 180

angle x = 180 - 120

angle x = 60

The sides is thus a triangle with angle 30-60-90.

For this case the sides are in the ratio:

x : x√3 : 2x

From the figure we see that, x = 4.

Thus, the remaining sides are:

x√3 = 4√3 and 2x = 2(4) = 8

Hence, the measure of the angle x is 60 degrees and the sides of the triangle is 4√3 and 8.

What is circle?

Each spot that is a particular distance from yet another point creates a circle in the plane (center). As a result, it is a curve composed of points separated in the plane by a given distance. Furthermore, at all angles, it is circumferentially symmetric the about centre. Every couple of points in such a circle's closed, two at least plane is evenly spaced out from the "centre." A round symmetry line is formed by tracing a line through circle. Furthermore, at all angles, it is rotationally equal about the centre.

The circumference of a circle can be calculated using the formula C = d, where d is the circle's diameter. Because the diameter in this case is 6 kilometres, the circumference is:

C = d = (6) = 18.85 km (rounded to two decimal places)

1/12 = 30 degrees / 360 degrees

As a result, the length of the 30 degree arc is:

A car averages 60 miles per hour on a road trip. Use the graph to represent the relationship between the time and the distance traveled.
please tell me the coordinates for the graphing because you have to graph it.

Answers

Using the speed formula, the coordinates to plot on the graph are (0, 0), (1, 60), (2, 120), (3, 180), and (4, 240).

What is the speed?

Speed is defined as the distance traveled per unit of time. It is the slope of the distance vs time graph. The formula for speed is:

Speed = Distance / Time

Where:

Speed is the speed of the object, usually expressed in units such as meters per second (m/s)

Distance is the distance traveled by the object, usually expressed in units such as meters

Time is the duration of travel, usually expressed in units such as seconds

To graph the relationship between the time and the distance traveled by the car, we can use the following formula:

Distance Traveled = Rate x Time

In this case, the rate (or speed) of the car is 60 miles per hour, and the distance traveled is a function of time.

So we can write the equation as:

Distance Traveled = 60 x Time

To graph this equation, we can plot a series of points using different values of time. For example:

At 0 hours, the distance traveled is 0 miles. Coordinate: (0, 0)

At 1 hour, the distance traveled is 60 miles. Coordinate: (1, 60)

At 2 hours, the distance traveled is 120 miles. Coordinate: (2, 120)

At 3 hours, the distance traveled is 180 miles. Coordinate: (3, 180)

At 4 hours, the distance traveled is 240 miles. Coordinate: (4, 240)

These points can be plotted on a graph with time on the x-axis and distance traveled on the y-axis. The resulting graph would be a straight line with a slope of 60 (which represents the rate or speed of the car) and passing through the origin (0, 0).

So the coordinates to plot on the graph are:

(0, 0), (1, 60), (2, 120), (3, 180), (4, 240)

A shop sells bottles of orange juice for £1.60, but will take 20% off the total cost when you buy more than 20 bottles. How much does it cost, in pounds (£), to buy 40 bottles of orange juice?​

Answers

Answer: 51.2 pounds

Step-by-step explanation: The problem states that 20% of the total cost is taken when you purchase more than 20 bottles.

We start by finding the total cost without the 20% off

Multiply the unit price by the number of bottles

[tex]1.60*40 = 64 pound[/tex]

Next use the discount, since we are getting 20% off we only have to pay 80% of it and 80/100 simplifies to 4/5 so we can just multiply 64 by that.

[tex]64*4/5 = 51.2[/tex]

The cost of buying 40 bottles of orange juice, with a 20% discount, is £51.20.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

The cost of one bottle of orange juice is £1.60.

To find the cost of 40 bottles of orange juice

40 bottles x 1.60 per bottle = £64

The total cost without the discount would be £64.

To calculate the discount, we can multiply the total cost by 20% or 0.20:

Discount = 20% x £64 = £12.80

The discount on 40 bottles of orange juice is £12.80.

To find the final cost, we need to subtract the discount from the total cost:

Final cost = Total cost - Discount

= £64 - £12.80

= £51.20

Therefore, the cost of buying 40 bottles of orange juice, with a 20% discount, is £51.20.

Find the area of a circle with a circumference of 31. 42 centimeters

Answers

From the given data in the question, the circumference of a circle is 31.42 centimeters then the area of the circle is 78.5 cm².

To find the area of a circle with a given circumference, we need to use the formula:

Circumference = 2πr

where π is the mathematical constant pi (approximately 3.14) and r is the radius of the circle. In this case, the circumference is given as 31.42 centimeters. So we can write:

31.42 = 2πr

To solve for r, we can divide both sides by 2π:

r = 31.42 / (2π)

r = 5

So the radius of the circle is 5 centimeters.

Now, to find the area of the circle, we can use the formula:

Area = πr²

Substituting the value of r, we get:

Area = π(5²)

Area = 25π

Area = 78.5 square centimeters

Therefore, the area of the circle with a circumference of 31.42 centimeters is approximately 78.5 square centimeters.

7. The sides of a rectangle are in the ratio 5:2. If the perimeter of the rectangle is 42 cm, find the area of the rectangle.​

Answers

Answer:

90 cm²

Step-by-step explanation:

Let the greater side be the length L and the smaller side the width W

Given L : W = 5 : 2

we can rewrite this as a fraction

[tex]\dfrac{L}{W} = \dfrac{5}{2}[/tex]

Cross-multiplying we get
2L = 5W

The perimeter of a rectangle
= 2(L + W)
= 2L + 2W
and we are told it is 42 cm

Therefore
2L + 2W = 42

Substitute 5W for 2L to get

5W + 2W = 42
7W = 42

or

W = 42/6 = 6

Given 2L + 2W = 42, substitute 6 for W to get

2L + 2(6) = 42

2L + 12 = 42

2L = 42 - 12= 30

L = 30/2 = 15

So length  L = 15

Just to check
L/W = 15/6 = 5/2  by dividing both numerator and denominator by 3

Area of the rectangle
= L x W

= 15 x 6

= 90 cm²

Katherine has $8.60 in dimes and quarters. If she has twelve more quarters than dimes, how many dimes does she have? How many quarters does she have?

Answers

After addressing the issue at hand, we can state that by function  Katherine now has 28 quarters.

what is function?

Mathematicians investigate numbers and their varieties, equations and adjacent tissues, shapes but instead their locations, and potential locations for these things. The term "function" refers to the relationship here between set of inputs, each with its own output. A function is a relationship of both inputs and outputs in which each input results in a single, distinct production. Each function has its own domain, codomain, or scope. The letter f is commonly used to denote functions (x). An x represents entry. On functions, each capabilities, so several capabilities, in capabilities, and on operations are the four major types of accessible functions.

Let's represent the unknown quantities with variables.

Let d be the number of dimes Katherine possesses.

Let q represent Katherine's number of quarters.

We can deduce from the problem:

Equation 1: Total dimes and quarters value = $8.60 0.10d + 0.25q = 8.60

Number of quarters = Number of dimes + 12 q = d + 12 Equation 2:

Now we can plug equation 2 into equation 1 to eliminate q and find d:

0.10d + 0.25(d + 12) = 8.60

Katherine now has 16 dimes.

We can use equation 2 to calculate the number of quarters:

q = d + 12 = 16 + 12 = 28

Katherine now has 28 quarters.

What step is needed when constructing a circle circumscribed about a triangle? (1 point)

Group of answer choices

Construct the angle bisectors of each angle in the triangle.

Construct the perpendicular bisectors of each side of the triangle.

Construct the midpoints of each side of the triangle.

Construct the altitude of each angle in the triangle.

Answers

The step needed when constructing a circle circumscribed about a triangle is option B: Construct the perpendicular bisectors of each side of the triangle.

What is the triangle construction about?

When constructing a circle circumscribed about a triangle, the center of the circle must lie at the intersection of the perpendicular bisectors of the sides of the triangle.

To construct the perpendicular bisector of a side, you need to find its midpoint and then draw a line perpendicular to the side passing through that midpoint.

By constructing the perpendicular bisectors of all three sides, you can find their point of intersection, which will be the center of the circle. Then, the radius of the circle can be found by measuring the distance from the center to any of the vertices of the triangle.

Therefore, Once you have the center and radius, you can draw the circle circumscribed about the triangle.

Antonio painted about 27% of the wall with melon color, 33% with green color, and 40% with white color.

Antonio painted a wall with an area of 15 square meters. He painted 4 square meters with melon color, 5 square meters with green color, and 6 square meters with white color.

To find the fraction of the wall that Antonio painted with each color, we need to divide the area painted with each color by the total area of the wall:

Fraction painted with melon color = 4 / 15 = 0.2666... ≈ 0.27

Fraction painted with green color = 5 / 15 = 0.3333... ≈ 0.33

Fraction painted with white color = 6 / 15 = 0.4

to decrease a number by 37% you multiply by 0.63
to decrease a number by 16% what do you multiply it by

Answers

To decrease a number by 16%, you should multiply it by 0.84.(1 - 0.16 = 0.84).

When you reduce a number by a percentage, you are subtracting that percentage from it. For example, if you were to decrease 100 by 16%, you would subtract 16 from 100 to get 84.

This is also known as a percentage decrease, which is the opposite of a percentage increase.

Using the formula for percentage decrease, we get:

Percentage decrease = (Decrease in value / Original value) × 100

We're told that to decrease a number by 37%, you multiply it by 0.63.

Therefore, we can write:

0.63 = (Decrease in value / Original value) × 1000.63 × Original value = Decrease in value

We want to find what you multiply a number by to decrease it by 16%, so let's call that value x.

So: x = (Decrease in value / Original value) × 100%

So, we can substitute in the values we know to solve for x:

x = (0.16 × Original value / Original value) × 100%x = 0.16 × 100%x = 16%

Therefore, to decrease a number by 16%, you should multiply it by 0.84.
