Answer:
Step-by-step explanation:
The null hypothesis is
H0: μ = 32.6
The alternative hypothesis is
Ha: μ ≠ 32.6
The calculated test statistic is 2.66 for the right tail and - 2.66 for the left tail
Since the critical values for both tails is ± 2.145, we would compare the critical values with the test statistic values
In order to reject the null hypothesis, the test statistic must be smaller than - 2.145 or greater than 2.145
Since - 2.66 < - 2.145 and 2.66 > 2.145, we would reject the null hypothesis.
Therefore, Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.
2) Test statistic: t = 2.66. Critical values: t = ±1.96
Since - 2.66 < - 1.96 and 2.66 > 1.96, we would reject the null hypothesis. Then
Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.

Answer:
The answer is 12.
Step-by-step explanation:
The question says QS is a tangent to circle P which means to QS is perpendicular 90° to QS. With provided information, we are able to find the value of QS using Pythogoras' Theorem, a²+b² = c² :
Let c = PR+RS = 5+8 = 13 units,
Let b = PQ = 5 units,
Let a = QS,
13² = 5² + QS²
QS² = 13² - 5²
= 169 - 25
= 144
QS = √144
= 12 units
Answer:
2
Step-by-step explanation:
6/9 * 3
First you can either simplify this to make it easier or directly multiply. Simplify it by dividing 3 on the 9.
6/3=2
Or you can multiply and it would be 18/9, because 6*3=18.
18/9=2
