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.

Some students equally share 2 baskets of apples. Each basket has 12 apples. Write an algebraic expression to represent this situ
Soloha48 [4]

Answer:

y = \frac{24}{x} is the algebraic expression to represent the situation.

Step-by-step explanation:

Given:

Some students equally share 2 baskets of apples.

Each basket has 12 apples.

To Find:

An algebraic expression to represent the situation = ?

Solution:

Let the number of students be x

The number of apple each one gets be y

then it is said that there are 12 apples in one basket.

So in two basket there will be

=> 2 \times 12

=> 24 apples

This 24 apples is to be shared among x students, so

Each student will get

y = \frac{24}{x}

Solve the equation below. Indicate which solutions, if any, are extraneous.<br> √ x+5 = x+3
ahrayia [7]

9514 1404 393

Answer:

  x = -1

Step-by-step explanation:

A graphical solution can avoid extraneous solutions. The attachment shows the one solution is x = -1.

__

Squaring both sides gives ...

  x +5 = (x +3)² = x² +6x +9

Putting this in standard form, we have ...

  x² +5x +4 = 0

  (x +1)(x +4) = 0 . . . . . factor

  x = -1 or -4 . . . . . . . . values of x that make the factors zero

__

Since we require the root to be non-negative, we must have ...

  x +3 ≥ 0

  x ≥ -3

The only solution that satisfies this requirement is x = -1. The solution x = -4 is extraneous. The solution is x = -1.
