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
Answer:
n-4=385. The answer is 389
The appropriate hypothesis which is used to test the dropout rate are
and
.
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=
=0.065
The hypothesis can be formed as under:
(null hypothesis)
( 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.

=
=-1.85
Hence the appropriate hypothesis are

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)
