Answer:

70cm^2

Step-by-step explanation:

10×5=50cm^2 is the area of the rectangle

18-10=8 is the height of the triangle

8×2.5=20

20÷2=10 is area of half the triangle

10+10=20cm^2 is the area of the triangle

50cm^2+20cm^2=70cm^2

Part A: The data that Zoe would expect to collect from this question is the amount of time each student spends playing video games. She could collect this data by asking each student how many hours per week they spend playing video games.

Part B: This is not a statistical question because it is asking for a specific answer. A statistical question would be asking for a distribution of the data, such as the average amount of time students spend playing video games or the range of times students spend playing video games.

To make this question statistical, Zoe could ask the following question:

How much time do students in my class spend playing video games per week?

This question is statistical because it is asking for a distribution of the data. Zoe could then collect the data and use it to create a histogram or other graph to show the distribution of the data.

150 cm far is the frog from the edge after 3 jumps. Therefore, option C is the correct answer.

1 jump the far from the edge

12/2 = 6 cm

2 jump the far from the edge

6/2 = 3 cm

3 jump the far from the edge

3/2 = 1.5 cm

We know that, 1 meter = 100 cm

Here, 1.5 cm = 150 cm

Therefore, option C is the correct answer.

The scientists may also be looking for changes in cognitive and motor skills due to the increased gravitational force.

The centrifuge is a device which is used to simulate the effects of gravity on humans. In this experiment, the centrifuge was 58 feet long and spun at 15 revolutions per minute.

This would create a centrifugal force which would be twice Earth's gravity. This would allow the scientists to study the effects of a much higher gravitational force on humans than they would experience on Earth.

The effects that would be studied could include changes in heart rate, blood pressure, and other physiological parameters. In addition, the scientists may also be looking for changes in cognitive and motor skills due to the increased gravitational force.

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

We are given that the center of the circle is (2, 3) and it contains the point (7, 15). To find the radius, we can use the distance formula between the center and the given point:

r = sqrt[(7 - 2)^2 + (15 - 3)^2]

r = sqrt[25 + 144]

r = sqrt(169)

r = 13

Substituting the given values into the equation of a circle, we get:

(x - 2)^2 + (y - 3)^2 = 13^2

Expanding the terms, we get:

x^2 - 4x + 4 + y^2 - 6y + 9 = 169

Simplifying and rearranging, we get:

x^2 - 4x + y^2 - 6y = 156

Therefore, the equation of the circle with center (2, 3) containing the point (7, 15) is:

x^2 - 4x + y^2 - 6y = 156

The calculated value of the conditional probability P(Not A | Not B) is 0.8125

From the question, we have the following parameters that can be used in our computation:

The table of values

The probability P(Not A | Not B ) is calculated as

P(Not A | Not B ) = (Not A and Not B)/(Not B)

Using the above as a guide, we have the following:

(Not A and Not B) = 0.65

(Not B) = 0.80

Substitute the known values in the above equation, so, we have the following representation

P(Not A | Not B ) = 0.65/0.80

Evaluate

P(Not A | Not B) = 0.8125

Hence, the probability P(Not A | Not B) is 0.8125

Answer:

  (c)  0 < a < 1

Step-by-step explanation:

You want to know the value of 'a' in y = a·cot(x) that will cause a vertical compression without reflection.

When a function value is multiplied by a factor greater than 1, its graph is expanded vertically. When that factor is less than 1, the graph is compressed, as in the attachment.

If the scale factor is negative, the graph will be reflected across the x-axis.

Here, you want compression without reflection. That requires a positive scale factor less than 1.

The bottle holds a total of 25 fluid ounce of iced tea.

from the question, we have the following parameters that can be used in our computation:

Volume of bottle = 750 milliliters of iced tea.

Also, we have

1 fluid ounce = 30 milliliters

This means that

1/30 fluid ounce = 1 milliliters

So, we have

Volume of bottle = 750 * 1/30 fluid ounce of iced tea.

Evaluate

Volume of bottle = 25 fluid ounce of iced tea.

Hence, the volume of bottle is 25 fluid ounce of iced tea.

The solution is: 100! different ways can you draw all of the names from the hat.

Here, we have,

if we have n object, and as we know that arrangement given by = n!. (Permutation)

A permutation is a mathematical technique for determining the number of possible arrangements in a sentence where the order of arrangements is important. A common math problem involves choosing some items in a particular order from a set of items.

A permutation also called an "order number" or "sequence", is the rearrangement of the elements of an ordered list so that they correspond one-to-one with themselves. (Faculty; Ouspensky 1937, p. 18). Permutations are said to be ordered combinations. The number of permutations r of n objects acquired simultaneously is determined by the following formula: P(n,r)=n!(n-r)!

Hereafter taking each unique name, we will arrange it in raw, so we can say this problem is equivalently permutation problem, So we can say the way of drawing all names can be done in 100! Way.

The probability of pulling out a red pair of socks and sport shorts is 12/35.

We have,

10 pairs of socks, 6 are red, and 7 shorts, 4 of which are sport shorts.

So, The probability of pulling out a red pair of socks is given by:

= (number of red socks) / (total number of socks)

= 6 / 10

= 3 / 5

and, the probability of pulling out sport shorts is given by:

= (number of sport shorts) / (total number of shorts)

= 4 / 7

To find the probability of both events happening together

= P(red socks) x P(sport shorts)

= (3 / 5) x (4 / 7)

= 12 / 35

Answer:

Step-by-step explanation:

The angle that has been formed and is shown as x is shown as 52.1°.

In a right triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. The tangent function is denoted as tan.

We can see that we need to find the tangent of the angle;

Tan x = 36/28

x = Tan-1(36/28)

x = 52.1°

1.1.1 If the ratio = opposite ; hypotenuse

⇒ It's the sinus.

In the triangle ABC it's :

sin(A) = opposite/hypotenuse

1.1.2 If the ratio = adjacent ; hypotenuse

In the triangle ABC it's :

cos(A) = adjacent/hypotenuse

1.1.3 If the ratio = opposite ; adjacent

tan(A) = opposite/adjacent

x has the ratio opposite ; adjacent

⇒ It's the tangente.

tan(x) = opposite/adjacent = 4/6

The quotient of -4 1/6 and -3 1/3 is 5/4.

To find the quotient of -4 1/6 and -3 1/3, we need to divide the two mixed numbers. Here's how we can do it:

Step 1: Convert the mixed numbers to improper fractions.

-4 1/6 can be converted to an improper fraction as follows:

-4 1/6 = -25/6

Similarly, -3 1/3 can be converted to an improper fraction as:

-3 1/3 = -10/3

Step 2: Divide the two improper fractions.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

So, (-25/6) / (-10/3) becomes (-25/6) * (-3/10).

Step 3: Simplify the resulting fraction.

Multiply the numerators and denominators:

(-25 * -3) / (6 * 10) = 75/60

Step 4: Simplify the fraction, if possible.

The numerator and denominator have a common factor of 15:

75/60 = (5 * 15) / (4 * 15)

Simplifying, we get:

75/60 = 5/4
