5/7+3/14= 10/14+3/14
10/14+3/14=13/14
13/14+4/7=13/14+8/14
13/14+8/14=21/14
21/14=3/2
The answer is 3/2.
I hope that helps!
Answer:
- motorcycles: 20
- vans: 25
- cars: 135
Step-by-step explanation:
There are 3 car spaces for each non-car space, so the number of car spaces is 3/4 of the total: (3/4)×180 = 135.
The number of motorcycle spaces is half of 5 less than the remainder, so is ...
(180 -135-5)/2 = 20
and van spaces are 5 more than that: 25.
There are 20 motorcycle spaces, 25 van spaces, and 135 car spaces.

$14.25
Step-by-step explanation:
$1.50 = 1 ticket
1.50 * 10 = 15
$15 = 10 tickets
100% - 5% = 95% (0.95)
15 * 0.95 = 14.25
$14.25
Answer:
95% Confidence Interval = (611.81 ppm, 696.51 ppm)
Step-by-step explanation:
The formula for Confidence Interval is given as:
Confidence Interval = Mean ± z × s /√n
Mean = the sample mean/average = 654.16
s = the sample standard deviation = 164.55
z = z score of 95% confidence interval = 1.96
Confidence Interval =
654.16 ± 1.96 × 164.55/√58
= 654.16 ± 42.348
Hence,
654.16 - 42.348
= 611.812
Approximately to two decimal places = 611.81 ppm
654.16 + 42.348
= 696.508
Approximately to two decimal places = 696.51 ppm
Therefore, the 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected is (611.81 ppm, 696.51 ppm).
I think #1 is -1/2 but im not sure i dont know about the other answers
