Answer:
A
Step-by-step explanation:
in option B, you are adding the 3 pound plastic box to each cardboard box
in option A, you have 5 separate carboard packages, and one 3 pound plastic box
This [option a] is the diagram that matches the scenario given.
Think of the x's as normal numbers. Let's say the weight of each "x" is 1. [it's not I'm aware that this question is different]
if you have 5 x's, you have
1 1 1 1 1 3
<em>not </em>1+3 ; 1+3 ; 1+3 ; 1+3 ; 1+3
you would only have this if you were to add a 3 pound plastic box to each individual package
Answer:
4
Step-by-step explanation:
when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor).
∴ when volume scale factor = 8
the length scale factor = ∛8 = 2
while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor).
∴ when the length scale factor = 2
the surface area scale factor = 2² = 4

Answer:
Step-by-step explanation:
The record of the statistics and the summary statistics which are the missing files in the question are attached below.
From the given information:
The null hypothesis and the alternative hypothesis can be represented by :
There is no difference between the average time spend by men and women at gym each week
The average time spend by men is greater than the average time spend by women at the gym each week
From the summary statistics in the attached file below:
The p-value = 0.3253
Level of significance = 5% = 0.05
Therefore; it is obvious that the p-value is greater than the level of significance i.e (0.3253 > 0.05)
Hence; there is no enough evidence to reject the null hypothesis
CONCLUSION: We conclude that the mean number of minutes exercised per week is larger for men than women at the this gym.
