Answer:

b = 3.1

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

10 5/18 - 8 5/6 <br> plzzzzzz helpppppp
adell [148]

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

The Rockwell hardness index for steel is determined by pressing a diamond point into the steel and measuring the depth of penetr
anygoal [31]

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, \bar{x} = 62

Sample size, n = 50

Alpha, α = 0.051

Sample standard deviation, s = 8

First, we design the null and the alternate hypothesis

H_{0}: \mu = 64\\H_A: \mu < 64

We use one-tailed(left) z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{62 - 64}{\frac{8}{\sqrt{50}} } = -1.767

Now, z_{critical} \text{ at 0.05 level of significance } = -2.33

Since,  

z_{stat} > z_{critical}

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.
