. Write an equation that is perpendicular to y=2x – 1 and has y-intercept of -3
blagie [28]

The answer is very simple .

First you need to determine the slope, which is the reciprocal of the first line.

Then,

y = mx + b

m => -1/m

The perperdicular line has a new slope equal to m = -1/2

In the formula (y - y1) = m ( x - x1 ) + b , you should sustitude this value.

So the final equation will be

-3 = -1/2 (0) + b

b = - 3

y = (-1/2)x - 3

That is the solution

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.

A family read the odometer before starting a trip .It read 22900.6 and they know they will be driving 302.5 miles . What's will
AlexFokin [52]

Answer:

23,203.1

Step-by-step explanation:

Generally, an odometer measures distance traveled during the usage life cycle of a car. It is necessary to say the distance is measured cumulatively.

Now, to get the value the odometer will be reading after the trip, we need to add the present reading of the odometer to the new distance to be traveled.

Thus, the reading of the odometer after the trip will be 22900.6 + 302.5 = 23,203.1
