15x+25=20x

Isolate x. Subtract 15x from both sides.
25= 5x

Now divide both sides by 5 to find the value of 1x.
5=x

Final answer: x=5

Find sin 0, where is the angle shown.<br> Give an exact value, not a decimal approximation.
hodyreva [135]

Answer:

sinθ = \frac{24}{25}

Step-by-step explanation:

By applying Pythagoras theorem in the given triangle,

Hypotenuse² = (Leg 1)² + (Leg 2)²

                      = (24)² + 7²

Hypotenuse = √625 = 25

By applying sine rule in the given triangle,

sinθ = \frac{\text{Opposite side}}{\text{Hypotenuse}}

Since, measure of opposite side = 24

Measure of hypotenuse = 25

Therefore, sinθ = \frac{24}{25} will be the answer.

Can some one help me
matrenka [14]
So again, you want to convert to decimals. 3 13/20=3.65 an 92/25= 3.68
so in order of least to greatest, you have 3 13/20, 92/25, 3.78, 3.788

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>
