The average amount of time that students use computers at a university computer center is 36 minutes with a standard deviation o
frosja888 [35]

Answer:

2119 students use the computer for more than 40 minutes. This number is higher than the threshold estabilished of 2000, so yes, the computer center should purchase the new computers.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 36, \sigma = 5

The first step to solve this question is finding the proportion of students which use the computer more than 40 minutes, which is 1 subtracted by the pvalue of Z when X = 40. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{40 - 36}{5}

Z = 0.8

Z = 0.8 has a pvalue of 0.7881.

1 - 0.7881 = 0.2119

So 21.19% of the students use the computer for longer than 40 minutes.

Out of 10000

0.2119*10000 = 2119

2119 students use the computer for more than 40 minutes. This number is higher than the threshold estabilished of 2000, so yes, the computer center should purchase the new computers.

You have already run 4 miles. If you run at a speed of 8 miles per hour, how many total miles will you run in 2 more hours? Choo
Inessa [10]

Answer:

20 miles

Step-by-step explanation:

I'm not sure if that is exactly how you solve it but

If its

8x+4 as the equation and x is the number of hours run

the total number of miles run should be 20 miles

8(2)+4=20

Which is equivalent to 16 3/4x ?
aliya0001 [1]
The answer

the question is not very clear, 
its complement may be <span>Which is equivalent to 16 ^ 3/4x?

-4√16^3x
-4√16^3
-3√16^4x
-3√16^4

perhaps the </span>16 3/4x should be written as [16 ^ 3] / 4x, or 16 ^  (3 / 4x)  
or - [16 ^  (3 / 4)]  x 

If the question is [16 ^ 3] / 4x, then none of the choices is equivalent to this
if the question is 16 ^  (3 / 4x), it is equivalent to 4x-th root of 16^3

so if the question is - [16 ^  (3 / 4)]  x 
so - [16 ^  (3 / 4)]  x  =( - 4√16^3)x  it is 4th root of 16^3 times x

so the choice is -4√16^3x
