Answer:
t ≈ 13.26
Step-by-step explanation:
We are given;
x¯ = 20 minutes per day
μ = 17 minutes per day
sample standard deviation; s = 1.6 minutes
Sample size; n = 50
When σ is unknown, formula for test statistic is;
t = (x¯ - μ)/(s/√n)
t = (20 - 17)/(1.6/√50)
t = 3/0.2263
t ≈ 13.26
Answer:
x=3
Step-by-step explanation:
Since all the angles are equal, this is an equilateral triangle. This means that all sides are equal
BC = AC
5x = 3x+6
Subtract 3x from each side
5x-3x =3x-3x+6
2x=6
Divide by 2
2x/2 =6/2
x=3
