zysi [14]

Answer:

The answer is (D): 2 h 52 min

Step-by-step explanation:

write these equations separately as functions:

A(x)=15+0.02m

B(x)=4.69+0.08m

Since we want to find when they are equal, set them equal to each other:

15+0.02m=4.69+0.08m

simplifying this equation gives

10.31+0.02m=0.08m

subtract 0.02m from both sides

10.31=0.06m

divide both sides by 0.06

m=171.833 etc approximately equals 172 minutes

172 min/60=

2 hours and 52 min

Hope this helps!

Consider a sample with a mean of 500 and a standard deviation of 100. What are the z-scores for the following data values: 560,

julsineya [31]

Answer:

z-score for value 560 = 0.6

z-score for value 650 = 1.5

z-score for value 500 = 0

z-score for value 450 = -0.5

z-score for value 300 = -2

Step-by-step explanation:

We are given a sample with a mean of 500 and a standard deviation of 100.

i.e., $\mu$ = 500 and $\sigma$ = 100

The z score distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where X represents the data values;

So, z score for value 560 is;

z score = $\frac{560-500}{100}$ = 0.6

So, z score for value 650 is;

z score = $\frac{650-500}{100}$ = 1.5

So, z score for value 500 is;

z score = $\frac{500-500}{100}$ = 0

So, z score for value 450 is;

z score = $\frac{450-500}{100}$ = -0.5

So, z score for value 300 is;

z score = $\frac{300-500}{100}$ = -2
