PLEASE HELP! SO Confused

Diano4ka-milaya [45]

Answer:

12.73 Degrees

Step-by-step explanation:

I'm going to assume some things. The height of the truck is not changing, i.e. the distance and length of the ramp are but the height stays the same.

We draw our right triangle, see photo*

We really only care about finding out what side a is so

$c = \frac{a}{sin(A)} \\12 = \frac{a}{sin(36)} \\12sin(36) = a\\a = 7.05342302750\\sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{12} )\\= 35.9999 \:degrees$

So, since I stated that height did not change, the same process just using 32 for the hypotenuse.

$sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{32} )\\= 12.73367164 \:degrees$

Determine the point estimate of the population proportion, the margin of error for the following confidence interval,and the num

Leya [2.2K]

Answer: The point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .

Step-by-step explanation:

Let $\overline{x}$ be the sample mean .

We know that the confidence interval for population mean is given by :-

$(\overline{x}-E,\overline{x}+E)$ , where E is the margin of error .

Given : Lower bound of the confidence interval = 0.226

Upper bound of the confidence interval =0.604

i.e.

$\overline{x}-E=0.226------(1)\\\\\overline{x}+E=0.604--------------(2)$

Adding (1) from (2), we get

$2\overline{x}=0.83\\\\\Rightarrow\ \overline{x}=0.415$

From (2),

$0.415+E=0.604\\\\\Rightarrow\ E=0.604-0.415=0.189$

Hence, the point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
