Answer: See below

Step-by-step explanation:

a) 6(3x+4y-8)

Use the distributive property:

6*3x + 6*4y - 6*8

18x + 24y - 48

<u>So D is the correct answer</u>

b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.

12+4x

= 4(3+x)

<u>So D is the correct answer</u>

c) When you expand both <u>C and D</u> and simplify, you get 16x+36 as solution

d) 14x+2y+10z

Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times

14x+2y+10z

= 2(7x+y+5z)

<u>So D is the correct answer again ;)</u>

Given that (x,y) = (5,15) find tan Ø. <br><br> A. 3 <br> B. 1/3 <br> C. 5 <br> D. 1/5
lesantik [10]
This value is in the positive quadrant meaning that all values remain positive. To answer this problem you must have an understanding of trig ratios being that tangent is opposite/adjacent. When you plot the points and draw a triangle using the origin of the point, you find that the adjacent value is 5 and opposite value is 15

A study was conducted looking at the association between the number of polyps in the colon and mean grams of fiber consumed per
rewona [7]

Answer:

C) The Spearman correlation results should be reported because at least one of the variables does not meet the distribution assumption required to use Pearson correlation.

Explanation:

The following multiple choice responses are provided to complete the question:

A) The Pearson correlation results should be reported because it shows a stronger correlation with a smaller p-value (more significant).

B) The Pearson correlation results should be reported because the two variables are normally distributed.

C) The Spearman correlation results should be reported because at least one of the variables does not meet the distribution assumption required to use Pearson correlation.

D) The Spearman correlation results should be reported because the p-value is closer to 0.0556.

Further Explanation:

A count variable is discrete because it consists of non-negative integers. The number of polyps variable is therefore a count variable and will most likely not be normally distributed.  Normality of variables is one of the assumptions required to use Pearson correlation, however, Spearman's correlation does not rest upon an assumption of normality. Therefore, the Spearman correlation would be more appropriate to report because at least one of the variables does not meet the distribution assumption required to use Pearson correlation.
