Answer:

For this equation to be true, a must = 13 and b must = 10 + 2i.

Step-by-step explanation:

First combine the numerators: 3 + 5 + 2i + 2, or 10 + 2i.

Next, multiply the denominators: 4 + 9 = 13

Then rewrite the original equation as:

10 + 2i a

---------- * ---- = 1

13 b

For this equation to be true, a must = 13 and b must = 10 + 2i.

Kipish [7]

Answer: $H_0:p\leq0.53$

$H_a:p>0.53$

Step-by-step explanation:

Claim : A a political strategist wants to test the claim that the percentage of residents who favor construction is more than 53%.

Let 'p' be the percentage of residents who favor construction .

Claim : $p> 0.53$

We know that the null hypothesis has equal sign.

Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-

$H_0:p\leq0.53$

And the alternative hypothesis must be :-

$H_a:p>0.53$

Thus, the null hypothesis and the alternative hypothesis for this test :

$H_0:p\leq0.53$

$H_a:p>0.53$

If m/8 =57, find m/1.

Valentin [98]

Answer:

696

Step-by-step explanation:

$\frac{m}{8} = 87$

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

$m=87*8\\m = 696$

Because any number divided by 1 would just be itself, 696/1 is just 696.
