Think of it this way. One times three is three Two times three is six. Three times three is nine. Four times three is twelve. Five times three is fifteen. Six times three is eighteen. Seven times three is twenty one . Eight times three is twenty four. Nine times three is twenty seven. Ten times three is thirty. Eleven times three is thirty three. Twelve times three is thirty six. Now, I think you have noticed that I went through all of the threes, and I came to a conclusion, that twelve is the answer! Another way is to do thirty six divide by three..Hope that this all would help you!

Professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot. find the recommended slope for a sewe

erik [133]

We have been given that professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot.

Therefore, we can find the slope as:

$\text{Slope}=\frac{0.25\text{ inch}}{\text{1 foot}}=\frac{0.25\text{ inch}}{\text{12 inch}}$

$\text{Slope}=\frac{0.25}{12}=\frac{25}{1200}=\frac{1}{48}$

Therefore, the recommended slope for a sewer pipe is $\frac{1}{48}$

An average computer mouse inspector can inspect 50 mice per hour. The 48 computer mice inspectors at a particular factory can on

Ronch [10]

Answer: C. Yes, because -2.77 falls in the critical region .

Step-by-step explanation:

Let $\mu$ be the population mean .

As per given , we have

$H_0:\mu=50\\\\ H_a: \mu$

Since the alternative hypothesis is left-tailed and population standard deviation is not given , so we need to perform a left-tailed t-test.

Test statistic : $t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}$

Also, it is given that ,

n= 48

$\overline{x}=46$

s= 10

$t=\dfrac{46-50}{\dfrac{10}{\sqrt{48}}}=\dfrac{-4}{\dfrac{10}{6.93}}\\\\=\dfrac{-4}{1.443}\approx-2.77$

Degree of freedom = df = n-1= 47

Using t-distribution , we have

Critical value = $t_{\alpha,df}=t_{0.025,47}=2.0117$

Since, the absolute t-value (|-2.77|=2.77) is greater than the critical value.

So , we reject the null hypothesis.

i.e. -2.77 falls in the critical region.

[Critical region is the region of values that associates with the rejection of the null hypothesis at a given probability level.]

Conclusion : We have sufficient evidence to support the claim that these inspectors are slower than average.

Hence, the correct answer is C. Yes, because -2.77 falls in the critical region

The graph of the function f is shown. The domain of f is [0,50]. What is the range of g(x)=4f(x)?

sergij07 [2.7K]

Answer:

The range of $g(x)$ is $[0,7]$ .

Step-by-step explanation:

We must remember that range of function $f(x)$ corresponds to the set of values of $y$ in the graph (+y direction). Given that $g(x)$ is a stretched version of $f(x)$ , the range of $g(x)$ corresponds to the range of $f(x)$ multiplied by 4. Then,

$Ran\{g(x)\} = 4\cdot Ran\{f(x)\}$

$Ran\{g(x)\} = 4\cdot [0,1.75]$

$Ran\{g(x)\} = [0, 7]$

The range of $g(x)$ is $[0,7]$ .
