In a September 2019 survey of adults in the U.S., participants were asked if within the last 5 years, they knew of a friend or f

amily member who died due to inability to pay for medical treatment. Overall, 13.4% answered yes. We have the breakdown of the data by three Age Groups. See the table below.AGE YES NO TOTAL18-44 87 428 51545-64 46 326 37265+ 14 198 212TOTAL 147 952 1099This problem will focus on a Difference of Proportion Problem between those 45 to 64 and those 65 and older. Use this order in calculating the difference so that the difference is positive. Answer the following questions.Construct a Confidence Interval of the difference in proportions. Do not assume equal variances for this calculation. Show all the parts: the estimated difference; the critical z-value, the standard error, the BOE, and the lower and upper values. Is zero within your confidence interval? Conduct a Hypothesis Test that the difference of the two proportions is zero. Use an alpha level of .01. This will be a 2-tailed test. Note that this requires a pooled estimated of the standard error.

The height of the cylinder is 25 inches and the radius of its base is 5 inches. What is the surface area of this cylinder, in te
Vikentia [17]

ok you need formula for surface area.

SA = πrh+2πr^2

Plug in 25 and 5

SA = 2π(5)(25)+2π(5)^2

SA = 10pi*25 + 2pi(25)

SA = 250pi + 50pi

SA = 300pi

Hope this helps :)

1/3(6x-15)=1/2(10x-4) solve for x
Tatiana [17]

Simplify 1/3(6x - 15) to 6x - 15/3

6x - 15/3 = 1/2(10x - 4)

Factor out the common term; 3

3(2x - 5)/3 = 1/2(10x - 4)

Cancel out 3

2x - 5 = 1/2(10x - 4)

Simplify 1/2(10x - 4) to 10x - 4/2

2x - 5 = 10x - 4/2

Factor out the common term; 2

2x - 5 = 2(5x - 2)/2

Cancel out 2

2x - 5 = 5x - 2

Subtract 2x from both sides

-5 = 5x - 2 - 2x

Simplify 5x - 2 - 2x to 3x - 2

-5 = 3x - 2

Add 2 to both sides

-5 + 2 = 3x

Simplify -5 + 2 to -3

-3 = 3x

Divide both sides by 3

- 1 = x

Switch sides

<u>x = -1</u>

A triangle has side lengths of 15 10 and 7 is it a right triangle
lions [1.4K]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Given:

The sides of the triangle =  15 10 and 7

To Find:

Whether the triangle is a right triangle = ?

Solution:

According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side

a^2 +b^2 =c^2\\

where

a and b are the smaller sides

c is the larger side

Now from the given data, lets assume

a = 10 and b =7 and c =15

Substituting in the above equation we get,

(10)^2 +(7)^2 = (15)^2

100 + 49 = 225

149 = 225

149 \neq 225

So, the given triangle is not a right triangle.

Can someone answer 8-11 please
vampirchik [111]

Answer:

7.9

4.2

9.3

17.8

Step-by-step explanation:

8. √63

the square of 8 is 64 √63 is close to 64 so we can say it's 7.9 approximately

9. √18

the square of 4 is 16, √18 is greater than 16 so we can say it's 4.2 approximately

10. √87

the square of 9 is 81, √87 is greater than 81 so we can say the value of it is approximately 9.3

11. √319

the square of 18 is 324, √319 is smaller than 324 so we can say it's 17.8
