Answer:
1.01 < µ < 1.03
Step-by-step explanation:
We want to construct a 95% confidence interval. Our sample size is 25, so we use a t-value. The degrees of freedom are 24 (always one less than the sample size).
The t-value we get is: 2.064
We have:
x = 1.02
σ = 0.03
See the attached photo for the construction of the confidence interval...

Answer:
8%
Step-by-step explanation:
new length = 110% x 30 = 33cm
new width = 105% x 20 = 21cm
new perimeter = 2(33 + 21) = 108cm
old perimeter = 2(30 + 20) = 100cm
percentage increase = 8/100 x 100% = 8%

Answer: n is 3
Step-by-step explanation: n can only be 3 as a triangle is the only polygon whose internal angles have a sum of 180 degrees
Answer:
x=-16
Step-by-step explanation:
We are given with the equation

We are asked to solve it for x.
Distributing
over bracket and simplifying




Adding 8 on both sides

Dividing both sides by -3
