Based on daily measurements, Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds, while Mary's weight h
soldi70 [24.7K]

Answer:

(C) They are the same

Step-by-step explanation:

The coefficient of variation CV is given by the following formula:

CV = \frac{\sigma}{\mu}

In which \sigma is the standard deviation and \mu is the mean.

Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds

This means that \sigma = 16, \mu = 200.

So his coefficient of variation is

CV = \frac{16}{200} = 0.08

Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.

This means that \sigma = 10, \mu = 125

So her coefficient of variation is

CV = \frac{10}{125} = 0.08

They have the same coefficient of variation, so the correct answer is.

(C) They are the same

A certain city garden has 64 flowers and 24 decora-
mars1129 [50]

Answer:

224 more flowers

Step-by-step explanation:

If the planner wants the ratio of flowers to shrubs to be 12:1, that means there will be 12 times as many flowers as shrubs.

Find what 12 times the number of shrubs is:

24(12)

= 288

So, the planner will need 288 flowers in total.

Find how many more he needs to plant by subtracting the current amount of flowers from 288:

288 - 64

= 224

So, the garden planner will need 224 more flowers.

Find two mixed numbers so that the sum is 21 1/6 and the difference is 4 3/6
docker41 [41]
A + b = 21 1/6 --> b = 21 1/6 - a
a - b = 4 3/6

a - (21 1/6 -a) = 4 3/6
a - 21 1/6 + a = 4 3/6
2a = 21 1/6 + 4 3/6
2a = 25 4/6
2a = 154/6
a = (154/6) / 2
a = (154/6) * (1/2)
a = 154/12 
a = 12 10/12
a = 12 5/6 

b = 21 1/6 -a
b = 21 1/6 - 12 5/6
b = 20 7/6 - 12 5/6
b = 8 2/6

Answer: 
a = 12 5/6
b = 8 2/6

Double check:

a + b = 12 5/6 + 8 2/6
a + b = 20 7/6 ......(7/6 = 6/6 + 1/6)
a + b = 21 1/6

a - b = 12 5/6 - 8 2/6
a - b = 4 3/6
