Answer: 19 miles

Step-by-step explanation:

Distance = speed × time

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. This means that the distance covered on her way to the train station is

0.5 × 10 = 5 miles

Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. Distance covered by the train is

0.5 × 28 = 14 miles

Therefore, the distance that Kristen travels to work is

14 + 5 = 19 miles

Set of data has a normal distribution with a mean of 56 and a standard deviation of 7. Find the percent of data within the follo
makvit [3.9K]

Answer:

.99815

which is about

99.815%

Step-by-step explanation:

we are looking for 35<x<77

We need to find (what I think is called) the z score which is acheieved through what I'm pretty sure is called standardizing

What we do is subtract the mean and then divide by the standard deviation

so for 35 we have

(35-56)/7= -3.29

due to the fact that the normal distribution is symmetric this is equal to 1-p(3.29)

to find p(3.29) grab a ztable and get p(3.29)= .9995

1-.9995= .0005

For 77 we have

(77-56)/7=3

grab a ztable and find the 3= .99865

Finally subtract these two to get the final answer

.99865-.0005= .99815

The table represents a linear function?
Llana [10]
Hello Fantaysias, 

How are you doing? I know this is kind of late, but here goes nothing! Yes, it is a linear equation, you know this because, the input always will result with the same output. Plus, since it has a slope, which is 10 by the way, it also confirms that this is linear! Linear means, that if you put these plots on a line, it will create a straight line! Hope I helped!

Thank you,
Darian D.
