Answer:

  1. the longer frame (B) has the shorter width

  2. the shorter width is 6 3/7 inches, area divided by length

Step-by-step explanation:

The relation between area, length, and width is ...

  A = LW

Then the width is ...

  W = A/L . . . . .  inversely proportional to length

__

1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.

__

2. The width of frame B is ...

  W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in

You have 480 roses and 24 of them dies, how many per cent died?
Setler79 [48]

Answer:

5%

Step-by-step explanation:

5% of the roses died.

480 roses = Total number of roses

24 roses = number of roses that died

24 roses that died as a percent of 480 the total is:

24/480*100= 5%

To find the percent of roses that died, we take the number of roses that died and divide it by the total amount of roses there are and multiply it by 100 to find the percent.

I'm a survey of 200 employees, 65% agreed that the management of the cafeteria should be changed. If the confidence interval is
suter [353]

Answer:

Step-by-step explanation:

Confidence interval for population proportion is expressed as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means probability of success

q = probability of failure

q = 1 - p

From the information given,

Sample proportion, p = 65/100 = 0.65

q = 1 - 0.65 = 0.35

n = 200

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 1.96. Thus, the z score for a confidence level of 95% is 1.96

Margin of error = 1.96√(0.65)(0.35)/200

Margin of error = 0.066 = 6.6%

The maximum boundary of the interval is

0.65 + 0.066 = 0.716

What is the coefficient of the term ​ 67xy ​? a.6/7 b.1/7 c.6xy d.6
notsponge [240]

A variable is an English letter we take for unknown values or quantities.We are given expression : \frac{6}{7}xy.

In the above given expression we have x and y English letters, because we don't know the values of them.

And we have some constant in front of those English letters.

We have \frac{6}{7} in front of xy.

<em>The coefficients are the constant numbers in front of variables.</em>

<h3>Therefore,  \frac{6}{7} is the coefficient of the term \frac{6}{7}xy.</h3><h3>Therefore, correct option is a. 6/7.</h3>
