A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
H0 : μ = 1
H1 : μ > 1
Sample size, n = 20 ; xbar = 1.05; Standard deviation, s = 0.13
Test statistic;
t because sample size is < 30
(xbar - μ) ÷ (s/sqrt(n))
(1.05 - 1) ÷ (0.13 / sqrt(20))
0.05 ÷ 0.0290688
= 1.7200572
Using a p value calculator :
With alpha = 0.05 ; df = n - 1 = 20 - 1 = 19
P value = 0.05084
P value > alpha
We fail to reject H0
There is not sufficient evidence to support that the new personnel are producing loaves that are heavier than 1 pound
Answer:
A. 40°
Step-by-step explanation:
∠Z=∠Y (base ∠ of isosΔ)
= 60°
∠X=180-60-60(∠ sum of Δ)
=40°
