Answer:

$\dfrac{3}{14}$

Step-by-step explanation:

The even number of minus signs means the product will be positive. A factor of 3 can be removed to simplify the product. As usual, the numerator of the product is the product of numerators, and the denominator of the product is the product of denominators.

$-\dfrac{1}{6} \times \left(-\dfrac{9}{7}\right)=\dfrac{1\cdot 9}{6\cdot 7}=\dfrac{3\cdot 3}{3\cdot 14}=\boxed{\dfrac{3}{14}}$

RoseWind [281]

Answer:

t=0.21

Step-by-step explanation:

Given $\bar x=69.2, s=10.9, n=125$ and a population mean $\mu=69$ .

#We state our hypothesis as:

$H_o:\mu=69\\\\H_a:\mu\neq 69$

The evidence available should validate either the null or alternative hypothesis.

#We calculate the test statistic as:

$t=\frac{\bar x-\mu_}{s/\sqrt{n}}\\\\\\=\frac{69.2-69}{10.9/\sqrt{125}}\\\\\\=0.2051$

$\approx0.21$

Hence, the test statistic is t=0.21

Solve this problem. What is x?

DedPeter [7]

a^2 + b^2 = c^2

a^2 = 6^2 + √117^2

a^2 + 36 = 117

a^2 = 117 - 36

a^2 = 81

a = √81

a = 9

x = 9
