Answer:
31.5
Step-by-step explanation:
The area of a triangle is 1/2 * b * h
so base times height times one half
Answer: 24X 1-(1/3)^n
1-(1/3)
Step-by-step explanation:
Answer:
μ > 21.21
Test statistic = 1.217
Kindly check explanation for more details
Step-by-step explanation:
The null hypothesis, H0 : μ = 21.21
Alternative hypothesis, H1 : μ > 21.21
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(21.212 - 21.21) ÷ (0.01 / √2)
= 1.217
The critical value :
From the t distribution :, one tailed = 2.434
Decision region :
Reject H0 if test statistic > critical value
1.217 < 2.434 ; We fail to reject the null ` ; and conclude that there is not enough evidence to support the claim.
-16 = 0.2b
Divide 0.2 on both sides to isolate b.
-16 ÷ 0.2 = -80
-80 = b
b = -80.
