Is the right arm or left arm stronger? Twenty five right handed people were studied. They were asked to do as many bicep curls a

s possible, first with their right arm and then with their left arm. Note:The differences were calculated as right-left. The 95% confidence interval for the true mean difference is (-9.242, 0.2472). Which of the following statements is the correct interpretation? Group of answer choices There is convincing evidence that the right arm can perform, on average, a different number of curls than the left arm. The left arm can perform more bicep curls than the right arm. The right arm can perform more bicep curls than the left arm. There is not enough evidence to say that the right arm and left arm can perform a different number of curls on average.

How do I do this problem

Do you mean 7?

You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)

1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.

2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.

3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.

4. The o term would stay as o^2 as there are not other o terms.

To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.

What fraction of the students in the class named baseball their favorite sport
mojhsa [17]

now, let's take a peek at the denominators, we have 3 and 8 and 12, we can get an LCD of 24 from that.

Let's multiply both sides by the LCD of 24, to do away with the denominators.

so, let's recall that a whole is "1", namely 500/500 = 1 = whole, or 5/5 = 1 = whole or 24/24 = 1 = whole.  So the whole class will yield a fraction of 1/1 or just 1.

\bf ~\hspace{7em}\stackrel{\textit{basketball}}{\cfrac{1}{3}}+\stackrel{\textit{soccer}}{\cfrac{1}{8}}+\stackrel{\textit{football}}{\cfrac{5}{12}}+\stackrel{\textit{baseball}}{x}~=~\stackrel{\textit{whole}}{1} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{24}}{24\left(\cfrac{1}{3}+\cfrac{1}{8}+\cfrac{5}{12}+x \right)=24(1)}\implies (8)1+(3)1+(2)5+(24)x=24 \\\\\\ 8+3+10+24x=24\implies 21+24x=24\implies 24x=3 \\\\\\ x=\cfrac{3}{24}\implies x=\cfrac{1}{8}

Find the derivative of f(x) = negative 9 divided by x at x = -8.
marusya05 [52]

Answer:

f'(-8)=\frac{9}{64}

Step-by-step explanation:

Given the function

f(x)=\frac{-9}{x}

We can rewrite it as

f(x)=-9x^{-1}

Now we can apply the power rule

f'(x)=9x^{-2}

Now we can rewrite it

f'(x)=\frac{9}{x^{2} }

Now we can plug in x=-8

f'(-8)=\frac{9}{(-8)^{2} }\\f'(-8)=\frac{9}{64}
