Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling. Before lunch they have collected a total of 173 cans. At the end of the day, the total number of cans collected can be represented by the expression 173 + n . What does the variable n in the expression represent?

Answers

Answer 1

Answer:

n = The number of can collected after lunch

Step-by-step explanation:

Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling.

From the question, the told number rod cans collected before lunch = n

We are told that :

At the end of the day, the total number of cans collected can be represented by the expression 173 + n .

The total number of cans = Number of cans collected before lunch + Number of cans collected after Lunch

Hence:

173 + n = 173 + Number of cans collected after Lunch

Therefore, the variable n = Number of cans collected after Lunch

A consumer magazine wants to compare the lifetimes of ballpoint pens of three different types. The magazine takes a random sample of pens of each type and conduct an ANOVA test. After the calculation, the F statistic is 1.62 and the p-value is 0.26. What is a correct decision at significance level of 0.1?

Answers

Answer: Fail to reject H0

Step-by-step explanation:

Given that:

P value = 0.26

α = 0.1

The values of both p and α can be compared in other to make a decision on whether to reject or fail to reject the Null hypothesis

Decisions :

If the p value > α (fail to reject null)

If p value < α ( Reject null)

In the scenario above :

0.26 > 0.1 ; p value > α

Since the p value is greater than alpha ; we fail to reject the Null

find the values of x and y?

Answers

Answer:x=20 y=70

Step-by-step explanation:

Answer:

x=20, y=70

Step-by-step explanation:

∠40°+∠adjacent to it =180°

∠adjacent= 180-40=140°

we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well

because sum of angles in a triangle has to be 180,

140 +x+x=180 so x=20°

from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70

In the slope-intercept form, which variable
represents the slope/measure of change?

Answers

Step-by-step explanation:

Hey there!

We know that the slope intercept is; y = mx+b.

Where "m" represents the slope. And "b" represents the y-intercept.

Example:

If the question is as; y = 3x +8

Then your slope of the slope intercept form is "3" where as "8" is y-intercept.

So, the variable"m" represents the slope.

Hope it helps...

Answer:

Option C

Step-by-step explanation:

Difference of the two expressions has been written as,

[tex]\frac{3x}{x^2-7x+10}-\frac{2x}{3(x-5)}[/tex]

To rewrite this expression as one expression,

First he factored the the denominators,

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x}{3(x-5)}[/tex]

Then Juan will make the denominators of both the terms equal,

For which he will multiply the second expression by [tex]\frac{x-2}{x-2}[/tex].

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x(x-2)}{3(x-5)(x-2)}[/tex]
