-4n-40=-2(7n+5) please show work

Mathematics
1 answer:
Grace [21]3 years ago
8 0

Answer:

n=3

Step-by-step explanation:

-4n-40=-2(7n+5)

Distribute the -2

-4n -40 = -14n -10

Add 14n to each side

-4n+14n -40 = -14n +14n-10

10n -40 = -10

Add 40 to each side

10n -40+40 = -10+40

10n = 30

Divide each side by 10

10n/10=30/10

n =3

Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the t
Korvikt [17]

Answer:

The <em>p</em>-value of the test is 0.0512.

Step-by-step explanation:

The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.

In this case the output of the t-test_ind method from scipy module is provided as follows:

Output = (-1.99, 0.0512)

The first value within the parentheses is the test statistic value.

So the test statistic value is, -1.99.

And the second value within the parentheses is the <em>p</em>-value of the test.

So the <em>p</em>-value of the test is 0.0512.

A ratio of two numbers is equal to 3:8. If the smaller number is 12,find the greater number.​
iragen [17]

<em>The other no. is:</em>

<u><em>32</em></u>

<em>As you can see that in the ratio given, </em><em>3</em><em> is the smaller no. and </em><em>12</em><em> too.</em>

<em>So when we divide </em><em>12 </em><em>by </em><em>3</em><em>, we get </em><u><em>4 </em></u>

<em>Then to find the other no. we need to multiply </em><em>4</em><em> with </em><em>8</em><em> (which is the other no.          in the ratio given)</em>

<em>Therefore, we get the other no. as </em><u><em>32</em></u>

<em>And also when you divide </em><em>12</em><em> by </em><em>32</em><em>, </em>

<em>You get the answer as </em><u><em>3</em></u><u><em> by </em></u><u><em>8</em></u><em> </em><em>(which is the given ratio) </em>

<em />

<em>Hope you found this helpful!</em>

<em>THANK YOU!!</em>
