Answer:
Well, you didn't show the equation . However we can generate an equation
by multiplying (x - 2.5) * (x +3)
x^2 -2.5x +3x -7.5 = 0
x^2 +.5x -7.5 = 0
DOUBLE-CHECK
Solving with the quadratic formula:
x = 2.5 and x = -3

Find the circumference of the circle by using the radius. The circumference of each clock is 37.7 inches. Multiply that by 10, because there are 10 clocks. That will give you your answer is 377 inches!
Answer:
The null hypothesis can't be rejected.
Step-by-step explanation:
Given information:
Null hypothesis:
H₀ : π ≤ 0.70
Alternative hypothesis:
H₁ : π > 0.70
We need to check whether the null hypothesis is rejected or accepted.
If P-value < α, then we reject the null hypothesis H₀.
If P-value ≥ α, then we accept the null hypothesis H₀.
A sample of 100 observations revealed that p = 0.75 at the 0.05 significance level.
Here 0.75>0.05, it means p > α, therefore we can not reject the null hypothesis.
The answer would be “1/8” because there are 8 sides on the die. So that’s 8/8 sides. Each side represents 1. It would be 1/8.
