The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equation can be used to find the maximum and minimum wait times at a bus stop?
Answer:
[tex]Max = 18\ mins[/tex]
[tex]Min = 12\ mins[/tex]
Step-by-step explanation:
Given
[tex]Time = 15\ mins[/tex]
[tex]Variation = 3\ mins[/tex]
Required
Determine the max and min values
The max value is calculated as thus:
[tex]Max = Time + Variation[/tex]
[tex]Max = 15\ mins + 3\ mins[/tex]
[tex]Max = 18\ mins[/tex]
The min value is calculated as thus:
[tex]Min = Time - Variation[/tex]
[tex]Min = 15\ mins - 3\ mins[/tex]
[tex]Min = 12\ mins[/tex]

Answer:

Step-by-step explanation:
The height h and collar size c , both in centimeters, measured from a sample of boys were used to create the regression line cˆ=−94+0.9h . The line is used to predict collar size from height, both in centimeters, for boys’ shirt collars. Which of the following has no logical interpretation in context?
Answer:
The C=intercept of the regression line
Step-by-step explanation:
The slope of the regression line has a logical interpretation as the average rate of change in collar size for a 1cm increase in height.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex]
The option that has no logical interpretation is: E The c-intercept of the regression line
From the question, we have:
[tex]^\wedge c = 94 + 0.9h[/tex]
Using the above representation of a regression line [tex]\wedge y = mx + c[/tex]
[tex]m \to[/tex] the slope
[tex]c \to[/tex] the y-intercept
By comparing [tex]\wedge y = mx + c[/tex] to [tex]^\wedge c = 94 + 0.9h[/tex]
[tex]0.9 \to[/tex] slope
[tex]94 \to[/tex] the y-intercept
While [tex]^ \wedge c[/tex] and [tex]h[/tex] are the variables (i.e. collar size and height)
From the list of given options (see attachment), the option that has no logical interpretation is:
E. The c-intercept of the regression line
This is because c does not represent the intercept of [tex]^\wedge c = 94 + 0.9h[/tex]

5,5,3 Is this a triangle? Explain.
8,8,8,Is this a triangle? Explain.
7,8,15 Is this a triangle? Explain.
5,6,10 Is this a triangle? Explain.
Please help me figure these problems out with the correct answers the last guy said they were all not triangles and my teacher said they were incorrect who ever answers and explains correctly gets 31 points and gets marked brainliest you have all the time you need so answer wisely. This shouldn't take long don't answer something your not similar with.
Problem 1
Answer: Yes a triangle can be formed with side lengths 5,5,3
--------------------
Explanation:
Take any two sides and add them up. If we get a sum larger than the third side, then a triangle is possible. This is the triangle inequality theorem.
5+5 = 10 is larger than 3
5+3 = 8 is larger than 5
This shows a triangle is possible. The triangle is isosceles because two sides are the same length.
==========================================================
Problem 2
Answer: Yes a triangle can be formed with side lengths 8,8,8
--------------------
Explanation:
This triangle is equilateral because all sides are the same length.
Take any two sides, add them up, and you'll find the sum is larger than the third side.
==========================================================
Problem 3
Answer: No a triangle cannot be formed with sides 7,8,15
--------------------
Explanation:
Yes it is true that
8+15 = 23 is larger than 7
7+15 = 22 is larger than 8
but
7+8 = 15 is not larger than 15
So this means a triangle is not possible.
Imagine you had 3 strips of paper that were 7 inches, 8 inches and 15 inches long. The 7 and 8 inch strips add to 15 inches, but those two smaller strips only form a straight line. We cannot pull them so a triangle forms. If we did, then the third side would be smaller than 15 inches. This is one way to get hands on to see why the triangle inequality theorem works.
==========================================================
Problem 4
Answer: Yes a triangle is possible with side lengths 5,6,10
--------------------
Explanation:
Same idea as before. We can take any two sides, add them, and get a sum larger than the third side. A triangle is possible.
5+6 = 11 is larger than 106+10 = 16 is larger than 55+10 = 15 is larger than 6This is the last one I need

Determine the slope for each side of the polygon.
The slope of side w is: _
The slope of side z is:_
The slope of side x is: _
The slope y is : _
Answer:
The slope of side w is: ¼
The slope of side z is: -4
The slope of side x is: ¼
The slope y is : -4
Step-by-step explanation:
Slope of w between (-1, 5) and (-5, 4):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 5}{-5 -(-1)} = \frac{-1}{-4} = \frac{1}{4} [/tex]
Slope of x between (-3, -4) and (1, -3):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 -(-4)}{1 -(-3)} = \frac{1}{4} = [/tex]
Slope of y between (-3, -4) and (-5, 4):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-4)}{-5 -(-3)} = \frac{8}{-2} = -4 [/tex]
Slope of z between (1, -3) and (-1, 5)):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-3)}{-1 - 1} = \frac{8}{-2} = -4 [/tex]
The slope of side w is
1/4
The slope of side z is
-4
The slope of side x is
1/4
The slope of side y is

Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $ 60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P, in terms of x, representing Cooper's total pay on a day on which he sells z dollars worth of computers.
Answer:
P = 0.015x + 60
Step-by-step explanation:
Since Cooper's base pay is $60, he would earn $60 even for selling $0 worth of computers, meaning P= 60 when x=0, which is the y-intercept.
(0,60) is a point on the graph
Since Cooper makes a commision of 1.5% for all sales, the amount of money earned in a given day increases $0.015 for each $1 of sales made (multiply 1 by 0.015). This means the slope of P is equal to 0.015.
