The price of the pear is $0.6
Given:
The total cost of lunch is $3.50, consisting of a juice, a sandwich, and a pear.The juice cost 1.5 times as much as the pear.The sandwich costs $1.40 more than the pear.
From above statements
Juice + sandwich + pear = $3.50 -----------eq(1)
Juice = 1.5 * pear
sandwich = pear + $1.40
substitute juice and sandwich values in eq(1)
1.5 pear + pear + $1.40 + pear = $3.50
3.5 pear = $3.50 - $1.40
pear = $2.10/3.5
pear = $0.60
Hence the price of the pear is $0.6

Answer:
Step-by-step explanation:
The formula for determining the confidence interval for the difference of two population means is expressed as
Confidence interval = (x1 - x2) ± z√(s²/n1 + s2²/n2)
Where
x1 = mean sale amount for mail order sales = 82.70
x2 = mean sale amount for internet sales = 66.9
s1 = sample standard deviation for mail order sales = 16.25
s2 = sample standard deviation for internet sales = 20.25
n1 = number of mail order sales = 17
n2 = number of internet sales = 10
For a 99% confidence interval, we would determine the z score from the t distribution table because the number of samples are small
Degree of freedom =
(n1 - 1) + (n2 - 1) = (17 - 1) + (10 - 1) = 25
z = 2.787
Margin of error =
z√(s²/n1 + s2²/n2) = 2.787√(16.25²/17 + 20.25²/10) = 20.956190
To find the perimeter, we must add together the length of each side.
The tick mark on the lines means they are equal, so that means we have two lines that are equal to 10
26 + 10 + 35 + 5 + 10 + (38 - 10) = 114"
Answer:
33.33%
Step-by-step explanation:
6 bikini styles and 2 other types
so, total types is 3
so, bikinis is only 1 of the 3, which is 1/3 or 33.33%
