Answer:
<u>3</u> fewer fluids ounces the regular bottle of sunscreen holds.
Step-by-step explanation:
Given:
The family size bottle of sunscreen holds = 12 oz.
The regular bottle holds 75% less.
Now, to find how much fewer fluids ounces does the regular bottle of sunscreen holds.
So, according to question:





Therefore, 3 fewer fluids ounces the regular bottle of sunscreen holds.
Answer:
95% confidence interval for the mean number of months is between a lower limit of 6.67 months and an upper limit of 25.73 months.
Step-by-step explanation:
Confidence interval is given as mean +/- margin of error (E)
Data: 5, 15, 12, 22, 27
mean = (5+15+12+22+27)/5 = 81/5 = 16.2 months
sd = sqrt[((5-16.2)^2 + (15-16.2)^2 + (12-16.2)^2 + (22-16.2)^2 + (27-16.2)^2) ÷ 5] = sqrt(58.96) = 7.68 months
n = 5
degree of freedom = n-1 = 5-1 = 4
confidence level (C) = 95% = 0.95
significance level = 1 - C = 1 - 0.95 = 0.05 = 5%
critical value (t) corresponding to 4 degrees of freedom and 5% significance level is 2.776
E = t×sd/√n = 2.776×7.68/√5 = 9.53 months
Lower limit of mean = mean - E = 16.2 - 9.53 = 6.67 months
Upper limit of mean = mean + E = 16.2 + 9.53 = 25.73 months
95% confidence interval is (6.67, 25.73)
Y=mx+b or -2=-1 x 2+b, b= -2(-1)(2) b=0
Therefore the equation of the line is
y=-1x
Answer:
0.27
Step-by-step explanation:
You take 1.75, and subtract 1.48 from it. 1.75
<u>- 1.48</u>
0.27
Answer:
120 degrees = H
Step-by-step explanation:
Two angles whose sum is equal to 180 degrees are called supplementary angles. do 180-60 to get 120
hope it helps! :)
