What are the blank numbers for 16, 17, 18, and 19

Natasha_Volkova [10]

Answer:

16: 0.5, 5, 7.5

17: 62, 434, 682

18: 12.3, 62.5, 10

19: 1, 75, 300

Step-by-step explanation:

16: 9/18=0.5 so halve the numbers

17: 186/3=62 so multiply numbers by 62

18: 24.6/2= 12.3 so multiply by 12.3 and divide for the last one

19: 125/5=25 so for the first one divide by 25 and for the last two times by 25

Can you help me from 1 to 8 and tell me how you get the answers for each one of them please

weqwewe [10]

Answer:

See below.

Step-by-step explanation:

1) 4x + 8 = 2x + 10

2x = 2

x = 1

2) 9y - 3 = 6y + 12

3y = 15

y = 5

3) 8m + 4 = 4m - 20

4m = -24

m = -6

4) 11z - 14 = 5z + 4

6z = 18

z = 3

5) 3q - 6 = 8q - 6

5q = 0

q = 0

6) 20n + 7 = 6n - 21

14n = -28

n = -2

7) 2w - 8 = 7w - 3

5w = -5

w = -1

8) 9k + 4 = k - 12

8k = -16

k = -2

On September 25, 2011 Michael Vick, the quarterback for the Philadelphia Eagles broke his non-throwing hand in a football game a

miskamm [114]

Answer:

D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.

Step-by-step explanation:

We have to calculate a 95% confidence interval for the population proportion. The population is made up of ESPN viewers.

The sample proportion is p=0.25.

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.25*0.75}{914}}\\\\\\ \sigma_p=\sqrt{0.00021}=0.014$

The critical z-value for a 95% confidence interval is z=1.96.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=1.96 \cdot 0.014=0.028$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.25-0.028=0.222\\\\UL=p+z \cdot \sigma_p = 0.25+0.028=0.278$

The 95% confidence interval for the proportion of ESPN viewers is (0.222, 0.278) or (22.2%, 27.8%).
