Falcons; they have a larger mean value of about 22.3 inches

Seahawks; they have a larger median value of 23 inches

Falcons; they have a larger median value of 22.5 inches

Answers

Answer:

The team that has the largest overall size hat for their players is the Seahawks; they have a larger mean value of about 23 inches. The correct option is C.

Step-by-step explanation:

What is the mean and median?

The two most frequently used measures of center are mean and median. When we compare the mean numbers for the Falcons and Seahawks, we can see that the Falcons have a mean of roughly 22 inches and the Seahawks have a mean of roughly 23 inches.

Nevertheless, when the data is skewed or contains outliers, the mean may not be the best approximation of the center because the mean can be altered by extreme values or outliers. Thus, we also need to compare the median values. The median is the midway value in the ordered set of data.

Thus, the correct option is C, Seahawks; they have a larger mean value of about 23 inches.

Which of the following are true statements about the expression 7 - (-7)7−(−7)7, minus, left parenthesis, minus, 7, right parenthesis?

Answers

To evaluate the expression 7 - (-7), we can simplify it step by step:

Step 1: Simplify the expression inside the parentheses.

-(-7) = 7

Step 2: Substitute the simplified expression back into the original expression.

7 - (-7) = 7 - 7

Now, let's analyze the given statements:

The expression equals 0.

False. The expression 7 - 7 does not equal 0. It equals 0 when multiplied by (-7), but in this case, the multiplication is not part of the expression.

The expression equals 14.

False. The expression 7 - 7 equals 0, not 14.

The expression is equal to the absolute value of 7.

False. The absolute value of 7 is 7, but the expression 7 - 7 is 0, not 7.

The expression is equal to the opposite of 7.

False. The opposite of 7 is -7, but the expression 7 - 7 is 0, not -7.

Therefore, none of the given statements are true about the expression 7 - (-7).

one sixth

6

Answers

Answer:

I believe it's 6, I'm super sorry if I'm wrong.

Step-by-step explanation:

I really hope this helps you!

To find the scale factor used to produce figure 1 from figure 2, we can divide the length of a leg in figure 1 by the length of the corresponding leg in figure 2.

Length of leg in figure 1 = 2 units
Length of leg in figure 2 = 6 units

Scale factor = Length of leg in figure 1 / Length of leg in figure 2 = 2/6 = 1/3

Therefore, the scale factor used to produce figure 1 from figure 2 is 1/3.

Answers

Step-by-step explanation:

Answer:

396 tacos

Step-by-step explanation:

for 50 people 72 tacos were sold

for 275 people a tacos were sold

50 people = 72 tacos

275 people= a tacos

cross multiplying

50 × a = 72 × 275

50a = 19800

diving both sides by 50

50a ÷ 50= 19800÷50

a=396 tacos

therefore if 275 people came,396 tacos will be sold

Answer:

Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Step-by-step explanation:

This is a rectangular prism given that the box has different lengths.

Stated dimensions for each box,

Box A:

Length = 13 1/2 (13.5) cm

Width = 3 cm

Height = 9 1/2 (9.5) cm

Box B:

Length = 14 cm

Width = 3 1/4 (3.25) cm

Height = 6 1/2 (6.5) cm

All we have to do, is find the volume of each box, compare them to each other, and determine which volume in which box is the greatest.

Now, in order to find the volume of a rectangular prism, use the formula:

V = L · W · H

Where "L" represents length, "W" stands for width, and "H" represents height.

Given all of these values from the box's dimensions, we only have to plug it in this formula to find the volume.

Let's find Box A's volume:

V = L · W · H

Substitute values:

V = 13.5 · 3 · 9.5

V = 40.5 · 9.5

V = 384.75

Let's find Box B's volume:

V = L · W · H

V = 14 · 3.25 · 6.5

V = 45.5 · 6.5

V = 295.75

Compare the two values to see which is the greatest:

384.75 __ 295.75

384.75 > 295.75, Box A's volume is greater.

Now we know that Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Answer:

(C) x = 56

Step-by-step explanation:

To find the value of x, we first need to find the measure of its supplement, or the angle which, when added to x°, results in 180°, or a straight line.

We can find the measure of its supplement by using the fact that the measures of the interior angles of a triangle add to 180°.

Hence, we can form the following equation to solve for the measure of the supplement.

37° + 19° + s° = 180°

s° = 124°

Now, we can subtract the measure of the supplement from 180° to get x°.

x° = 180° - 124°

x° = 56°

We can cancel the degrees on both sides of this equation to solve for x.

(C) x = 56

Solve inequality for X

x-c/d > y (For d > 0)

A. x < dy - c
B. x > dy - c
C. x < dy + c
D. x > dy + c

Answers

Answer:

D. x > dy + c.

Step-by-step explanation:

To solve the inequality x - c/d > y, we'll isolate the variable x.

First, let's multiply both sides of the inequality by d:

d(x - c/d) > dy

Expanding the left side:

dx - c > dy

Next, let's rearrange the terms to isolate x:

dx > dy + c

Finally, divide both sides of the inequality by d:

x > dy/d + c/d

Therefore, the solution to the inequality x - c/d > y, for d > 0, is:

x > dy/d + c/d

Guidelines for a wheelchair ramp allow a maximum of 1 in. of rise for every 12 in. of run. The ramp at the left runs 6 ft 8 in. and rises 2 ft 9 in. Does the ramp meet the guidelines?

yes

Answer:

First, we need to convert the lengths of the run and rise to inches. 6 ft 8 in. is equal to 72 + 8 = 80 in. and 2 ft 9 in. is equal to 24 + 9 = 33 in.

The guidelines state that the ramp should have a maximum of 1 in. of rise for every 12 in. of run. So, if the ramp has a run of 80 in., the maximum rise should be 80/12 = 6.67 in.

The ramp at the left has a rise of 33 in., which is greater than the maximum of 6.67 in. Therefore, the ramp does not meet the guidelines.
