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:
{x| x is a real number}
Step-by-step explanation:
f(x) is defined for all values of x, so the domain is ...
{x| x is a real number}
Answer:
2.5in
Step-by-step explanation:
Given parameters;
Base = 4.5inches
Height = 6inches
Area = 21in²
Unknown:
b₂ = ?
Solution:
Formula for finding the area of a trapezium;
A = 
x h
Input the parameters and solve for b₂;
21 = 
x 6
21 = 3(4.5 + b₂)
21 = 13.5 + 3b₂
21 - 13.5 = 3b₂
b₂ = 2.5in
The number rounded to the nearest tenth is 54 degrees
Answer:
v = Δs/Δt
Step-by-step explanation:
This: Δs is the change in speed or can also be the rate
This: Δt is the change in time
