The respiratory rate (in breaths per minute) in newborns varies according to a distribution that is approximately Normal, with a

maks197457 [2]

Answer:

$P(40$

And since we need to use excel the code in order to find the answer would be:

=NORM.DIST(55,50,5,TRUE)-NORM.DIST(40,50,5,TRUE)

And the answer would be:

$P(40$

Step-by-step explanation:

Let X the random variable that represent the respiratory rate of a population, and for this case we know the distribution for X is given by:

$X \sim N(50,5)$

Where $\mu=50$ and $\sigma=5$

We are interested on this probability

$P(40$

And since we need to use excel the code in order to find the answer would be:

=NORM.DIST(55,50,5,TRUE)-NORM.DIST(40,50,5,TRUE)

And the answer would be:

$P(40$

A chemical company makes two brands of antifreeze. The first brand is 20% pure antifreeze, and the second brand is 45% pure anti

Hoochie [10]

The gallons of the first brand of antifreeze should be 60 gallons.

The gallons of the second brand of antifreeze should be 90 gallons.

<h3>What are the linear equations that represent the question?</h3>

0.2f + 0.45s = 52.50 (0.35 x 150) equation 1

f + s = 150 equation 2

Where:

f = gallons of the first antifreeze
s = gallons of the second antifreeze

how many gallons of each brand of antifreeze must be used?

Multiply equation 2 by 0.2

0.2f + 0.2s = 30 equation 3

Subtract equation 3 from equation 2

0.25s = 22.50

s = 22.50 / 0.25

s = 90

f = 150 - 90 = 60 gallons
