Can u pls help me with this question asap

Zinaida [17]

Answer:

3.5/1 (or just 3.5)

Step-by-step explanation:

If y = a/n, then the constant proportionality is 3.5/1 or 7/2

Think of this as "rise over run" (we are basically finding the slope)

zalisa [80]

The length of CD is 7-3=4.

Therefore, if we dilate by a scale factor of 3, the length is 4(3) = 12

Is a triangle with sides of 9in, 25in, 24in a right triangle

Veronika [31]

Try the case if the triangle was a right triangle.
Then the longest side, 25, would be c or the hypotenuse.
9^2+24^2=25^2
81+576=625
657=625
This is not a true statement so the triangle is not a right triangle.

Hope this helps :)

Carisoprodol, a generic muscle relaxer, claims to have, on average, at least 120 milligrams of active ingredient. An independent

katovenus [111]

Answer:

The approximate p-value for the suitable test

<em>0.05 < p < 0.1</em>

|t| = |-1.5806| = 1.5806

t = 1.5806 < 2.009 at 0.05 level of significance

<em>Carisoprodol, a generic muscle relaxer, claims to have, on average, is equal to 120 milligrams of active ingredient.</em>

<u>Step-by-step explanation</u>:

<u><em>Step(i)</em></u>:-

Given mean of the Population 'μ' = 120 milligrams

Given random sample size 'n' = 50

Given mean of the sample x⁻ = 116.2 milligrams

Standard deviation of the sample 'S' = 17 milligrams

Null hypothesis : 'μ' = 120

Alternative hypothesis : 'μ' < 120

<u><em>Step(ii):</em></u>-

<em>Test statistic </em>

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{116.2 - 120}{\frac{17}{\sqrt{50} } } = \frac{-3.8}{2.404} = -1.5806$

<em>Degrees of freedom</em>

<em>ν = n-1 = 50 -1 =49</em>

t₀.₀₅ = 2.009

|t| = |-1.5806| = 1.5806

t = 1.5806 < 2.009 at 0.05 level of significance

<em>Null hypothesis is accepted</em>

<em>Carisoprodol, a generic muscle relaxer, claims to have, on average, is equal to 120 milligrams of active ingredient.</em>

<u><em>P- value:-</em></u>

<em>The test statistic |t| = 1.5806 at 49 degrees of freedom</em>

<em>The test statistic value is lies between 0.05 to 0.1</em>

<em>0.05 < p < 0.1</em>

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