Answer:

See below.

Step-by-step explanation:

Part A: A system will have no solution when the graphs are parallel and do not intersect.

Part B: A system will have no solution when the equations have the exact same slope. The same slope means they are parallel and do not intersect. This is done easiest in slope-intercept form.

3 people can pave a driveway in 4 hours.How long will it take for 8 people to pave a driveway?

Gala2k [10]

In order to determine how log will take for 8 people to pave a driveway you use the given proportion: 3 people pave a driveway in 4 hours.

By a simple rule of three you have:

3/4 = 8/x

Where you have peeple in the numerator and time in hours in the denominator.

You solve the previous equation for x:

3/4 = 8/x

x = (8/3)*(4) = 32/3 = 10.66

Then, 8 people will take approximately 10 hours plus 40 minutes to pave a driveway

The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are

USPshnik [31]

The appropriate hypothesis which is used to test the dropout rate are $H_{0}:p > =0.081\\$ and $H_{1}: p < 0.081$ .

Given Drop out rate through 24 year old who are not enrolled is 8.1%, sample size=1000 and we have to find the hypothesis to test the drop out rate of the school.

The variable which needs to be studied is X=Number of individuals with age between 16 and 24 years old that are high school dropouts.

The parameter of interest is the proportion to high school drop outs is p.

Sample proportion= $p^{1}$ =0.065

The hypothesis can be formed as under:

$H_{0}:p > =0.081$ (null hypothesis)

$H_{1}:p < 0.081$ ( alternate hypothesis)

Null hypothesis is a hypothesis which is tested for its validity and alternate hypothesis is hypothesis which is opposite of null hypothesis means if null hypothesis is rejected then the alternate hypothesis will be true.

$Z_{H_{0} }=(p^{1}-p)/\sqrt{p*(1-p)/n}$

= $0.065-0.081/\sqrt{(0.081*0.0919)/1000}$

=-1.85

Hence the appropriate hypothesis are $H_{0}:p > =0.081$ and $H_{1}:p < 0.081$ .

The vertices of ∆PQR are P(–2, –4), Q(2, –5), and R(–1, –8). If you reflect ∆PQR across the y-axis, what will be the coordinates

yawa3891 [41]

A reflection around the axis and is given by the following rule:
(x, y) ----> (-x, y)
Applying the rule to each vertex we have:
(-2, -4) ----> (2, -4)
(2, -5) ----> (-2, -5)
(-1, -8) ----> (1, -8)
Answer:
the coordinates of the vertices of the image ΔP'Q'R 'will be:
P '= (2, -4)
Q '= (- 2, -5)
R '= (1, -8)
