Assume G And H Are Whole Numbers, And G &lt; H. Which Expression Has The Least Value?

Answers

Answer 1

Expression B has the least value if  g and h are whole numbers, and

g < h.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Given that,

g < h

To determine which expression has the least value, we need to simplify each expression as much as possible and compare the results.

First, let's simplify expression A:

A = (h + g) * (h - g)

 = h*h - g*g

Next, let's simplify expression B:

B = h*h- 2hg + g*g

Finally, let's simplify expression C:

C = h*h + 2hg + g*g

Now we can compare the expressions. We know that g < h, so g*g < h*h. Therefore, the smallest value will be produced by the expression with the smallest coefficient for the h*h term.

A has a coefficient of 1 for the h*h term, while B and C have coefficients of -2h and 2h, respectively. Since h is positive, -2h is the smallest coefficient, so expression B has the smallest value.

Therefore, expression B has the least value.

Which represents the distance between A(6, 5) and B(−2, −1)?

Answers

Answer:

10

Step-by-step explanation:

We can use the distance formula to find the distance between the two points:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates of A and B, we get:

Distance = √((-2 - 6)^2 + (-1 - 5)^2)

Distance = √((-8)^2 + (-6)^2)

Distance = √(64 + 36)

Distance = √100

Distance = 10

Therefore, the distance between A(6, 5) and B(−2, −1) is 10 units.

A piece of cheese has a mass of 216 g and a density of 1.6 g/cm³. Calculate the volume of the cheese.​

Answers

The formula states that volume equals mass divided by density so u would do 216g/1.6g/cm^3=.135L I think this how u do it cause I’m not sure about which units to use

The volume of the cheese is approximately 135 cubic centimeters.

To calculate the volume of the cheese, we can use the formula:

Volume = Mass / Density

Given that the mass of the cheese is 216 grams and the density is 1.6 g/cm³, we can plug these values into the formula:

Volume = 216 g / 1.6 g/cm³

Now, we need to convert the units so that they are consistent. Since density is given in grams per cubic centimeter (g/cm³), we need to convert the mass from grams to cubic centimeters.

1 gram is equal to 1 cubic centimeter, so:

Volume = 216 cm³ / 1.6 cm³

Now, divide:

Volume ≈ 135 cm³

The volume of the cheese is approximately 135 cubic centimeters.

A firm has classified its customers in two ways: according to whether the account is overdue and whether the account is new (less than 12 months) or old. An analysis of the firm's records provided the input for the following table of joint probabilities: One account is selected at random. If the account is overdue, what is the probability that it is new? If the account is new, what is the probability that it is overdue?

Answers

The probability that it is new is 0.0833.

The probability that it is overdue is 0.25.

How to calculate conditional probability?

To solve this problem, use conditional probability.

Let A be the event that the account is new, and B be the event that the account is overdue.

A) To find the probability that an account is new given that it is overdue, calculate:

P(New | Overdue) = P(New and Overdue) / P(Overdue)

P(New | Overdue) = 0.05 / (0.05 + 0.55) = 0.0833 or 8.33%

So the probability that the account is new, given that it is overdue, is 8.33%.

B) To find the probability that an account is overdue given that it is new, calculate:

P(Overdue | New) = P(Overdue and New) / P(New)

P(Overdue | New) = 0.05 / (0.05 + 0.15) = 0.25 or 25%

So the probability that the account is overdue, given that it is new, is 25%.

Answers

The variance of the sample is 17.05. However, none of the given options matches with this value. The closest option is option (d) 16.5.

What is variance?

Variance is a measure of the spread or variability of a set of data. It is the average of the squared differences from the mean. The formula for variance is:

Variance = (sum of squared deviations from the mean) / (number of observations - 1)

where the squared deviation from the mean is the difference between each data point and the mean of the data set, squared. The variance is useful in statistical analysis and can provide information about the distribution of the data. A higher variance indicates that the data is more spread out, while a lower variance indicates that the data is clustered more closely around the mean.

In the given question,

To find the variance of the sample, we can use the formula:

Variance = [(sum of squared deviations from the mean)/ (number of observations - 1)]

First, we need to find the squared deviation of each observation from the mean, which is the difference between each observation and the mean, squared:

(3-5.4)² = 5.76

(5-5.4)² = 0.16

(12-5.4)² = 43.56

(3-5.4)²= 5.76

(2-5.4)²= 12.96

Next, we need to sum up these squared deviations:

5.76 + 0.16 + 43.56 + 5.76 + 12.96 = 68.2

Then, we divide the sum of squared deviations by the number of observations minus 1:

Variance = 68.2/(5-1) = 17.05

Therefore, the variance of the sample is 17.05. However, none of the given options matches with this value. The closest option is option (d) 16.5.

What is the surface area of the cylinder? Use π = 3.14 and round to the nearest whole number.

251 m2
301 m2
502 m2
804 m2

Answers

The surface area of a right circular cylinder can be found by adding the area of the two circular bases and the lateral surface area.

The area of each circular base is πr^2, where r is the radius. In this case, the radius is 4 meters, so the area of each circular base is:

π(4)^2 = 16π

The lateral surface area is the area of the rectangle that forms the curved surface of the cylinder. The height of the rectangle is the same as the height of the cylinder, which is 8 meters, and the base of the rectangle is the circumference of the circle, which is 2πr. So, the lateral surface area is:

8(2πr) = 16πr

Substituting r = 4, we get:

16π(4) = 64π

Adding the areas of the two circular bases and the lateral surface area, we get:

16π + 16π + 64π = 96π

Using π = 3.14 and rounding to the nearest whole number, the surface area of the cylinder is:

Answers

The percent rate of change to the nearest tenth of a percent is approximately 30.0% for both forms.

Starting with [tex]Y=5e^{-0.7}[/tex]  we can rewrite it using the property that [tex]e^{In(x)} = x[/tex]:

[tex]y=5e^{0.7t} = 5e^{ine^{in-0.7t} } =5e^{ln(5)}e^{-0.7t}[/tex]

Using the property that e^(ln(x)) = x again, we can simplify further:

[tex]y = 5e^{(ln(5)} e^{-0.7t} = 5(5^{1/In(5)}e^{-0.7t})[/tex]

Let [tex]a = 5^{1/ln(5)}[/tex]and r = 0.7, then we have:

[tex]y = 5a(1 + r)^{-t} ; y = a(1 - r)^t[/tex]

Rounding r to the nearest thousandth, we have:

r ≈ 0.700

To find the percent rate of change, we can use the formula:

percent rate of change = (1 ± r) * 100%

For the first form, we have:

percent rate of change = (1 - 0.700) * 100% ≈ 30.0%

For the second form, we have:

percent rate of change = (1 - 0.700) * 100% ≈ 30.0%

The safe distance between the supports to carry the load of 1500 pounds is found to be 8 meters.

Explain about the inverse proportion?

One kind of proportionality relationship is inverse proportion. If two quantities remain inversely related, one will increase while the other will decrease.

The area of a circle is proportional to its radius, which serves as an illustration of direct proportion.

The equation for inverse proportion of the weight carried along with distance is:

P = 5400 /D

P is load in pounds (lb)

D is the safe distance.

Then, distance to carry 1500 lb of load is:

1500 lb = 1500*0.45 kg

1500 lb = 675 kg

675  = 5400 /D

D = 5400/675

D = 8 meters

Thus, safe distance between the supports to carry the safe load of 1500 pounds is found to be 8 meters.

A parallelogram of base 12cm has an area 108sq. Cm. Find the height

Answers

The height of the parallelogram is 9 cm.

To find the height of a parallelogram with a given base and area, we can use the formula:

Area = base x height

In this case, we are given that the base of the parallelogram is 12 cm and the area is 108 sq. cm. Substituting these values into the formula, we get:

height = 108/12

Simplifying this expression, we get:

height = 9cm

A parallelogram is a four-sided polygon with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and parallel to each other. The opposite angles are also equal in measure, meaning that the adjacent angles are supplementary (their sum is 180 degrees).

A bicycle wheel make five rotations. The bicycle travel 30. 09 find the diameter

Answers

The diameter of the wheel is approximately 1.918 meters.

We can use the formula:

distance traveled = circumference of wheel x number of rotations

The circumference of the wheel is equal to the distance traveled in one rotation, which is equal to the diameter of the wheel times pi (π). So we can rewrite the formula as:

distance traveled = (diameter of wheel x π) x number of rotations

where d is the diameter of the wheel.

We are given that the bicycle travels 30.09 meters and the wheel makes five rotations, so we can plug in these values:

30.09 = (d x π) x 5

Solving for d, we get:

d = 30.09 / (π x 5)

d ≈ 1.918 meters
