Answer:
C
Step-by-step explanation:
First we find the z-score.
z = (x - μ) / σ
z = (520 - 500) / 60
z = 0.33
Using a calculator or z-score table:
P(z < 0.33) = 0.6293
The probability is approximately 63%. Answer C
I’m not sure but I’m commenting Bc I really need an answer I’m so sorry
Answer:
The hypotenuse to the nearest tenth is 8.1
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
Let a be the x leg and b be the y leg
a = 7 units
b= 4 units
7^2 + 4^2 = c^2
49+ 16 = c^2
65 = c^2
Take the square root of each side
sqrt(65) = sqrt(c^2)
8.062257748 =c
To the nearest tenth
8.1 =c

Answer:
745.31
Step-by-step explanation:
1. 12.5^2 * 2 = 312.5
2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
