Answer: (7,-27)

Step-by-step explanation:

The coordinates of mid point of a line segment having endpoints (a,b) and (c,d) is given by :-

x=\dfrac{a+c}{2}\ ;\ y=\dfrac{b+d}{2}

Given : The midpoint of UV is (5,-11). The coordinates of one endpoint are U(3,5).

Let the coordinates of endpoint V be (a,b), then we have

5=\dfrac{3+a}{2}\ ;\ -11=\dfrac{5+b}{2}

\Rightarrow\ 10=3+a\ ;\ -22=5+b  [Multiply 2 both sides]

\Rightarrow a=10-3\ ;\ b=-22-5

\Rightarrow a=7\ ;\ b=-27

Hence, the coordinates of endpoint V = (7,-27)

Determine the point estimate of the population proportion, the margin of error
ahrayia [7]

Answer:

\hat p=0.645\\\\ME=0.233\\\\x=645 \ individuals

Step-by-step explanation:

-Given the boundaries as 0.412 and 0.878

-\hat p is the point estimate for the population proportion and is calculated as follows:

\hat p=\frac{Upper \ Bound+Lower \ Bound}{2}\\\\=\frac{0.878+0.412}{2}\\\\=0.645\\\\

#The margin of error, ME can be calculated for the confidence intervals using the formula:

ME=\frac{Upper \ Bound-Lower \ Bound}{2}\\\\=\frac{0.878-0.412}{2}\\\\=0.233

#The number of individuals in the sample is the product of the point estimate and population size:

\hat p=\frac{x}{n}\\\\x=\hat pn\\\\=0.645\times 1000\\\\=645

Hence, there are 645 individuals in the sample.
