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%.

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 :-

$H_a:p>0.53$

Select the expression that has a value of 28. (4 points)

anastassius [24]

Answer:

(8 + 4 × 6) ÷ 2 + 7

Step-by-step explanation:

8 + (4 × 6) ÷ 2 + 7 = 27

8 + 24 ÷ 2 + 7

8 + 12 + 7

8 + 4 × 6 ÷ (2 + 7) = $10\frac{2}{3}$

8 + 4 × 6 ÷ 9

8 + 24 ÷ 9

$8 + 2\frac{2}{3}$

$10\frac{2}{3}$

(8 + 4 × 6) ÷ 2 + 7 = 23

(8 + 24) ÷ 2 + 7

32 ÷ 2 + 7

16 + 7

(8 × 4) + 6 ÷ 2 − 7 = 28

32 + 6 ÷ 2 - 7

32 + 3 - 7

35 - 7

e-lub [12.9K]

First, subtract the height he will grow to to the height he is now.

132 - 90 = 42

Now divide this from 3.5.

42 / 3.5 = 12

So it will take 12 months for him to grow to a height of 132 cm.
