Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
Find the value of x.
First, multiply -1 from both sides.
(-3/4x)(-1)<12(-1)
Solve.
12(-1)=-12
3/4x<-12
Next, multiply 4 from both sides.
4*3/4x<4(-12)
Solve.
Multiply the numbers from left to right.
4(-12)=-48
3x<-48
Then, divide by 3 from both sides.
3x/3<-48/3
Solve.
Divide the numbers from left to right.
-48/3=-16
X<-16
The correct answer is x<-16.

Step-by-step explanation:
Answer:
lowest score a college graduate must earn to qualify for a responsible position is 578
correct option is D. 578
Step-by-step explanation:
given data
mean = 500
standard deviation = 50
distribution = 6 %
to find out
What is the lowest score a college graduate must earn to qualify for a responsible position
solution
we know that here Probability P that is express as
P ( Z > x ) = 100% - 6% .....................1
so with the help of normal table
here value of Z is = 1.55 from cumulative probability 0.94
so by z score formula here x will be
x = z × standard deviation + mean ................2
so put here value
x = 1.55 × 50 + 500
x = 577.7387 ~ 578
so lowest score a college graduate must earn to qualify for a responsible position is 578
I'm not sure what the answer can be for this
