Answer:

Option: c is the correct answer.

He completes 1.25 of inspection in 1 hour.

Step-by-step explanation:

Robert can complete 10 inspections in 8 hours.

Unit rate is defined as how much of something per unit of something else.

He completes 10 inspection in 8 hours.

or we can say that in 8 hour he completes 10 inspections.

So, in 1 hour he completes: 10/8 inspections=1.25 inspections.

Hence, option:c is correct.

He completes 1.25 of inspection in 1 hour.

The correct answer would be 1.25 inspections an hour because you just need to divide 10 by 8 and you should get 1.25. Hope this helps.

Hunter-Best [27]

\huge\fbox{Answer ☘}

7(8) - 6 \div 2 + (a)3 = 107 \\ 56 - 3 + 3a = 107 \\ 53 + 3a = 107 \\ 3a = 107 - 53 \\ 3a = 54 \\ a =  \cancel\frac{54}{3}  = 18

A data set includes weights of garbage discarded in one week from 62 different households. The paired weights of paper and glass
lara [203]

Answer:

Because the absolute value of the test statistic is <u>less than</u> the positive critical value, there <u>is not</u> enough evidence to support the claim that there is a linear correlation between the weights of discarded paper and glass for a significance level of α = 0.05.

Step-by-step explanation:

The correlation​ matrix provided is:

Variables    Paper     Glass

  Paper           1         0.1853

 Glass        0.1853         1

Te hypothesis for the test is:

<em>H</em>₀: <em>ρ</em> = 0 vs. <em>H</em>₀: <em>ρ</em> ≠ 0

The test statistic is:

<em>r</em> = 0.1853 ≈ 0.185

As the alternate hypothesis does not specifies the direction of the test, the test is two tailed.

The critical value for the two-tailed test is:

r_{\alpha/2, (n-2)}=r_{0.05/2, (62-2)}=r_{0.05/2, 60}=0.250

The conclusion is:

Because the absolute value of the test statistic is <u>less than</u> the positive critical value, there <u>is not</u> enough evidence to support the claim that there is a linear correlation between the weights of discarded paper and glass for a significance level of α = 0.05.

Answer:

Volume=Length×Width×Height

Step-by-step explanation:

A rectangular prism is a 3D figure with 6 rectangular faces. To find the volume of a rectangular prism, multiply its 3 dimensions: length × width × height. The volume is expressed in cubic units.

EXAMPLE:

Lets say the HEIGHT is 2mm. Lets say the WIDTH is 1mm. Lets say the LENGTH is 10mm.

L×W×H

10×1×2=20mm

20 Cubic mm
