Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 ) = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725

<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>

p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )

= P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116 ( using Z-table )

What is the equation of this trend line?<br> RE<br> Enter your answers b y filling in the boxes.

Deffense [45]

Answer:

$K=-2J+28$

Step-by-step explanation:

step 1

Find the slope of the line

The formula to calculate the slope between two points is equal to

$m=\frac{k2-k1}{j2-j1}$

we have the points

(2,24) and (6,16)

substitute in the formula

$m=\frac{16-24}{6-2}$

$m=\frac{-8}{4}$

$m-2$

step 2

Find the equation of the line in slope intercept form

$K=mJ+b$

we have

$m=-2$

$b=28$ ----> the k-intercept is the point (0,28) see the graph

substitute

$K=-2J+28$
