Move both constants to the right than change the sign
4b=-9-3
then calculate -9-3 which is -12
now we have 4b=-12
now we isolate 4 by dividing both sides of the equation
4b= -12
which is
b= -3
so no
8 x 2 1/4 = 18
the stack is 18 in. thick.
Hope this helps!!

The correct answer would be 5.
P is being divided with r
Answer:
Mean value is 0 and standard deviation is 1 after all test scores have been standardized by converting them to z-scores using z
Step-by-step explanation:
In a standard normal distribution (also called as Gaussian distribution) all values of the sample can be projected to a normal distribution with mean 0 and standard deviation 1 using their z-scores.
z-score of a value X can be calculated as follows:
z= where
50 is the mean of the test scores
6 is the standard deviation of test scores
