It’s 60 degrees because it’s on triangle

Mama L [17]

The answer is $-\frac{1}{2}$

First you must change the fractions so that they have like denominators.

$\frac{10}{12} -\frac{16}{12}$

Then you subtract the fractions.

$-\frac{6}{12}$

Finally, you need to simplify the answer.

$-\frac{1}{2}$

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421

Step-by-step explanation:

We know that the sample proportion have the following distribution:

$\hat p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by $\alpha=1-0.90=0.1$ and $\alpha/2 =0.05$ . And the critical value would be given by:

$z_{\alpha/2}=-1.64, z_{1-\alpha/2}=1.64$

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

And on this case we have that $ME =\pm 0.04$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}$ (b)

We assume that a prior estimation for p would be $\hat p =0.5$ since we don't have any other info provided. And replacing into equation (b) the values from part a we got:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421

Will give brainliest to whoever answers both questions!! I need to turn this in soon!

Harman [31]

Answer:

y=55x

given y=385

x=gallons of gas = 385/55 = 7 gallons

inverse function

y=55x

change x to y and y to x

x=55y

y=x/55

inverse function is x/55

Alik [6]

In general,

$(f\cdot g)(x)=f(x)\cdot g(x)$

Therefore, in our case,

$(f\cdot g)(x)=(0.5x{}^2-2)(8x^3+2)=4x^5-16x^3+x^2-4$ <h2>The answer is 4x^5-16x^3+x^2-4. Select 4, 16, 1, 4 (left to right)</h2>
