The ratio of selling price to cost price is. 3.65 : 1.72
The cost price is 28.50 and you want to find the selling price so let x replace that spot
x : 28.50
cross multiply 3.65 × 28.50 and 1.72 × x
3.65 × 28.50 = 104.025
1.72 × x = 1.72x
104.025 = 1.72x
x is approximately $60.48
Answer:
The 90% confidence interval for the mean µ of the population of female runners.
( 65.0328 , 66.5672)
Step-by-step explanation:
<u>Step(i)</u>
Given A sample of 12 runners showed a sample mean height of 65.80 inches and a sample standard deviation of 1.95 inches.
Given sample size is n = 12 <30 so small sample
Given sample mean (x⁻) = 65.80 inches
sample standard deviation (S) = 1.95 inches.
<u>Step(ii)</u>
Assume the population is approximately normal.
The 90% confidence interval for the mean µ of the population of female runners.

substitute all above interval

The degrees of freedom γ=n-1 = 12-1=11
From t- table = 1.363 at 90 % 0r 0.10 level of significance

on calculation , we get
(65.80 -0.7672 ,65.80 + 0.7672)
( 65.0328 , 66.5672)
Answer:
simplest fraction: 2 1/3 the tick marks split the number into 7 regions
Step-by-step explanation:
The red heart is on the 2 tick mark of the 6 ticks between 2 and 3. The answer is 2 2/6 which after simplifying if equal to 2 1/3.
1. The answer would be about 20.72, or 20.7142 if you don’t want the rounded version
2. The answer is -12.8
