V = Bh for h. A. h = BV B. h=B/V C. h=V/B D. h = V – B

1 answer:

5 0

C. h=V/B to solve for this you need to get the variable h by itself and since h is being multiplied to B you use the opposite operation of division by divide both sides by B. Then you have h solved for h=V/B

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtain

slega [8]

Answer: 8359

Step-by-step explanation:

The formula for sample size needed for interval estimate of population proportion :-

$n=p(1-p)(\frac{z_{\alpha/2}}{E})^2$

Given : The significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}}=z_{0.025}=\pm1.96$

Previous estimate of proportion : $p=0.32$

Margin of error : $E=0.01$

Now, the required sample size will be :-

$n=0.32(1-0.32)(\frac{1.96}{0.01})^2=8359.3216\approx8359$

Hence, the required sample size = 8359

Find the value of x?

Deffense [45]

Answer:

145°

Step-by-step explanation:

See the attachment. Angles A, B, and C all belong to the triangle.

We know that A + B + C = 180° since the angles of a triangle always add to 180°. We also know that when two lines meet that their sum is also equal to 180°. So we can write for each interior angle the following:

<u> Result</u>

<A = (180 - 88) 72

<B = (180-x) 180-x

<C = (180 - 127) 53

The sum of angles A, B, and C is equal to 180:

72 + (180-x) + 53 = 180

What is the solution of log(t-3)=log(17-4t)?

solmaris [256]

Log=13
t=4
So, this is because they already given you t because the four is on front of it that gives you your value. From there you will proceed to j7st do the math in your parentheses. You should get log=(1) & log=(13) because 1 times anything is that number just use the inverse of each would be eachother. So, 1x13 is the same as 13x1
