The average hourly salary of workers at a supermarket is $14.50 with a standard deviation of $1.75. the shaded area of which curve represents the probability of the hourly salary being between $9.25 and $12.75?

0.1574

Step-by-step explanation:

Given that X, the average hourly salary of workers at a supermarket is $14.50.

X is Normal with mean = 14.50 and std dev = 1.75

In other words, the variable

Z= is normal with (0,1) as mean and variance

the probability of the hourly salary being between $9.25 and $12.75

P(

after converting X into Z

Hence area will be represented by the shaded area in the attached file

Prob =0.1574

Step-by-step explanation:

For all Plato users

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
