Use the lists of common factors to answer the question

Bezzdna [24]

Answer:

9 and 40

21 and 40

Step-by-step explanation:

I just did the test on edg. 2020

Factors of 9:

1,3,9

Factors of 15:

1,3,5,15

Factors of 21:

1,3,7,21

Factors of 40:

1,2,4,5,8,10,20,40

We have to find the pairs of numbers which are relatively prime.

Relatively prime number: The numbers in which gcd 1 are called relative prime numbers.

a.9 and 15

GCD(9,15)=3

9 and 15 are not relatively prime.

b.9 and 40

GCD(9,40)=1

Hence, 9 and 40 are relatively prime.

c.9 and 21

GCD(9,21)=3

9 and 21 are not relatively prime.

d.15 and 21

GCD(15,21)=3

15 and 21 are not relatively prime.

e.21 and 40

GCD(21,40)=1

21 and 40 are relatively prime.

the weights of bags of baby carrots are normally distributed, with a mean of 34 ounces and a standard deviation of .35 ounces. b

taurus [48]

Answer:

The carrots can weight atmost 34.59 ounces so that it does not need to be repackaged.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 34 ounces

Standard Deviation, σ = 0.35 ounces

We are given that the distribution of weights of bags is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.045

$P( X > x) = P( z > \displaystyle\frac{x - 34}{0.35})=0.045$

$= 1 -P( z < \displaystyle\frac{x - 34}{0.35})=0.045$

$=P( z < \displaystyle\frac{x - 34}{0.35})=0.955$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 34}{0.35} = 1.695\\\\x = 34.59325\approx 34.59$

Thus, the carrots can weight atmost 34.59 ounces so that it does not need to be repackaged.
