The answer is C. This is because when you covert the fraction into a decimal, you get 2.33333(etc) and the decimal doesn’t end.
Answer:

5
Step-by-step explanation:
Basically isolate X,
(Sorry, I don't have time to explain deeply)
Hope I helped!! :)
F(x)= -x^3+x ( don’t add the ^ but replace it with the 3 if you know what i mean )
The coordinates are 8, -3.
Answer:
p-value (0.0208) is less than alpha = 0.05 reject H0.
Step-by-step explanation:
we have the following data:
sample size = n = 75
x, the number to evaluate is 45
the sample proportion would be: x / n = 45/75
p * = 0.6
Now, the null and alternative hypotheses are:
H0: P = 0.72
Ha: P no 72
two tailed test
statistic tes = z = (p * - p) / [(p * (1-p) / n)] ^ (1/2)
replacing we have:
z = (0.6 - 0.72) / [(0.72 * (1-0.72) / 75)] ^ (1/2)
z = -2.31
p-vaule = 2 * p (z <-2.31)
using z table, we get:
p-vaule = 2 * (0.0104)
p-vaule = 0.0208
Therefore, p-value (0.0208) is less than alpha = 0.05 reject H0.
