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

For all Plato users

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
