The answer to your problem is x= 15/8 as decimal form it’s 1.875
When x=-2, y=4x = 4(-2) = -8 .
Answer:
The probability is 0.080757
Step-by-step explanation:
We start by calculating the z-score
z-score = (x-mean)/SD/ √n
In this case;
x = 247 , mean = 240, SD = 50 and n = 100
z-score = (247-240)/50/√100
z-score = 7/50/10
= 7/5 = 1.4
So the probability we want to calculate is;
P( x > 1.4)
we can use the standard normal distribution table for this
P(x > 1.4) = 0.080757
Umm I can't really explain but like everyone knows that a rectangle had four sides so if each side is multiplied by x then it's going to be that number to the fourth power because you know 4 sides four x's but I not 100% sure just wanted to help out
