A) 3 dollars
b) P = 0.5x - 475
c)950
d)-200
Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?

b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?

Hence, a) 0.8413, b) 0.9987.

Answer:
The value of x is 14
Step-by-step explanation:
The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because
9 ÷ 3 = 3
so this would mean that 5 was dilated by 3 also. So to figure this out, it would be
5 × 3 = 15
1 of that 15 is already there.
So this means that
15-1=14
A=14
I hope this helps you.
Answer:
-7
Step-by-step explanation:
Let's try getting rid of the numbers to isolate the x.
Add x on both sides to get rid of the x on the right side and to get 2x on the left side. This leaves us with 15.3 + 2x = 1.3
Subtract 15.3 on both sides to get rid of the 15.3 on the left side.
This would leave us with 2x = -14
Divide 2 on both sides to isolate the x.
The answer is x = -7
