Answer:
-5/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(518×11)−(56×33)=?
Complete the multiplication and the equation becomes
518−1518=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
5−1518=−1018
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 18 using
GCF(10,18) = 2
−10÷218÷2=−59
Therefore:
518−56=−59
Answer:
We conclude that the steel has an average hardness index of at least 64.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 64
Sample mean,
= 62
Sample size, n = 50
Alpha, α = 0.051
Sample standard deviation, s = 8
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We fail to reject the null hypothesis and accept the null hypothesis. Thus, we conclude that the steel has an average hardness index of at least 64.
