g In 2013, the Pew Research Foundation reported that 43% of U.S. adults report that they live with one or more chronic condition

SOVA2 [1]

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 43\% = 0.43$

The standard error is $SE = 0.017$

Given that the confidence level is 95% then the level of significance is mathematically represented as

$\alpha = (100-95)\%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * SE$

=> $E = 1.96 * 0.017$

=> $E = 0.03332$

Generally 95% confidence interval is mathematically represented as

$\r p -E < p < \r p +E$

=> $0.43 -0.03332 < p < 0.43 + 0.03332$

=> $0.39668 < p < 0.46332$

Converting to percentage

$(0.39668 * 100)< p < (0.46332*100)$

$39.7\% < p < 46.33 \%$

Find the area, in square units, of ️ABC

Anna [14]

Answer:

52 square units

Step-by-step explanation:

For this you need the length of CB and the length of DA.

|CB| = √(10²+2²) = 2√26

|DA| = √(10²+2²) = 2√26

area of ABC = base · height / 2 = 2√26 · 2√26 / 2 = 52

Answer: If you are supposed to graph a line, it will be a horizontal line (parallel to the x-axis) passing through +3 on the y-axis. The slope is 0.

it is a function.

If you are doing range and domain, the range is [3] and the domain is [1,2,3,4,5]

Step-by-step explanation: If there are directions above question 1 that apply to question 2, please add them to the comments.

Maybe someone else will be able to help if it is too late for me to edit this answer.
