A pair of dice is rolled. If you know one of the dies shows a 5, what is the probabiility that the sum is 8.
Answers
Answer:
5/36
Step-by-step explanation:
So a pair of dice is rolled. 2 dices. A dice has 6 numbers (1,2,3,4,5,6).
Now draw a sample space.
1 2 3 4 5 6
1 2 3 4 5 6 7
2 3 4 5 6 7 8
3 4 5 6 7 8 9
4 5 6 7 8 9 10
5 6 7 8 9 10 11
6 7 8 9 10 11 12
It's asking for SUM, so we plus. Thats why you see this.
So look for all the 8's in the sample space. Theres one in (6,2), (5,3), (4,4), (3,5) and (2,6). Thats 5. We divide that with the total. The total is 36 because there are 36 possible values. so 5/36

Julie made 25 international long-distance phone calls to London last month. The scatterplot below shows the length and cost of each phone call she made. Which conclusion is best supported by the scatterplot? As the length of a call increases, the cost of the call remains the same. As the length of a call increases, the cost of the call increases. There is no relationship between the length of a call and the cost of a call. As the length of a call increases, the cost of the call decreases.
Answers
Answer:
There is no relationship between the length of a call and the cost of a call.
Step-by-step explanation:
If we consider the scatter plot, we will discover that there is no identifiable relationship between the cost of calls and the length of calls.
We can't see any increases or decrease of call cost with call length from the plot. Hence, there is no relationship between the length of a call and the cost of a call.

Annabella Works in a deli and has been tracking the daily sales of different items over several months Annabelle found that when there was an increase in the number of cups of hot chocolate sold the number of cups of coffee sold also increased similarly where there was a decrease in the number of cups of hot chocolate sold the number of cups of coffee also decrease which of the following is a valid conclusion
Answers
I would assume that even though both hot chocolate and coffee increased and decreased at the same time, they are not a correlation since one doesn’t cause the other to increase/decrease
Answer:
The increase in the sale of hot chocolate is correlated to, but not caused by, the sale of coffee.

b(20) = 60
Step-by-step explanation:
Here, given that ;
b(x) = -2(x-50)
we want to find the value of b(20)
what we need to do is to simply substitute x for 20
That will be:
b(20) = -2(20-50)
b(20) = -2(-30)
b(20) = 60

Quadrilateral ABCD is shown. Two students each perform a different reflection on the original figure.
Use the drop-down menus to give the coordinates of point B' after each reflection.
Answers
Answer:
Pauline reflected the original figure over the x-axis:
The coordinates of point B will be (4,3)
Carl reflected the original figure over the y-axis:
The coordinate of points B will be (-4,-3)
When Pauline reflect the original figure over the x-axis, the coordinate of point B' will be (-2, -4). When Carl reflect the original figure over the y-axis, the coordinate of point B' will be (2, 4).
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
In Mathematics, a reflection over the x-axis is given by this transformation rule:
(x, y) → (x, -y)
Point B = (4, -3) → Point B' = (4, 3)
In Geometry, a reflection over the y-axis of a graph is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, the coordinates of point B' after a reflection over the y-axis is as follows:
Point B = (4, -3) → Point B' = (-4, -3)

Andy is designing a dice tray in the shape of a rectangular prism to use during a role-playing game. The tray needs to be three centimeters high and have a volume of 252 cubic centimeters in order for the dice to roll properly. The length of the tray should be five centimeters longer than its width. The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the height.

Answer:
Andy is designing a dice tray in the shape of a rectangular prism to use during a role-playing game. The tray needs to be three centimeters high and have a volume of 252 cubic centimeters in order for the dice to roll properly. The length of the tray should be five centimeters longer than its width.
The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the height.
Complete the equation that models the volume of the tray in terms of its width, x, in centimeters.
3x2 + 15x = 252
Is it possible for the width of the tray to be 7.5 centimeters?
no it is too large
Step-by-step explanation:
An equation is formed when two equal expressions. The equation that models the volume of the tray in terms of its width, x, in centimeters is 3x² + 15x - 252 = 0.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the width of the rectangular prism die be represented by x.
Given that the length of the tray should be five centimeters longer than its width. Therefore, the length and the width of the prism can be written as,
Width = x
Length = x + 5
Further, it is given that the volume of die is 252 cubic centimeters in order for the dice to roll properly. Also, the height of the prism is 3 centimeters. Therefore, the Volume can be written as,
Volume = Length × Width × Height
252 = (x + 5) × x × 3
252 = 3x(x+5)
252 = 3x² + 15x
3x² + 15x - 252 = 0
Hence, the equation that models the volume of the tray in terms of its width, x, in centimeters is 3x² + 15x - 252 = 0.

1. Explain why the sine law cannot be used to find the length of the third side of a triangle when
the known angle is contained between the two known sides
Answers
Answer:
The law of Sines is used to determine a missing side or angle measurement
Step-by-step explanation:
When saying Sine Law, I am pretty sure you mean the Law of Sines.
This is the equation
a/sine a = b/sine b
To use the Law of Sines you need 2 angle measurements and 1 side length, or 2 side lengths and 1 angle measurements. Law of Sines is used to find the missing angle or side. Not to find the third side.
To find the length of the third side you would use pythagorean theorem.

Find the slope of the sides of the given quadrilateral from following figures.
Answers
Answer:
side DA = side CB = slope is Undefined
side DC = side AB = slope is 0
Step-by-step explanation:
To find the slope we use the following
m = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex]
The slope for side DA is the same as side CB; also their value for x value will be the same on the line; leaving the bottom of the slope equation at 0.
That means that side DA = side CB = slope Undefined
The slope for side DC is the same as side AB; also their value for y value will be the same on the line; leaving the top of the slope equation at 0.
That means that side DC = side AB = slope 0

the distance between two towns is 300 km two cars start simultaneously from this towns and move towards each other the speed of one car is more than the other by 7 km per hour if the distance between the cars after 2 hours is 34 kilometre find the speed of the cars
Answers
Answer: I think its 131.19, but not too sure.
Step-by-step explanation:
To find the speed, you would do distance/time, so I added 300 and 7. I got 307, then I divided 307 (distance) from 2.34 (time). I got 131.19
Do you want the speed of both cars? then the answer would be:
(300)- first car= 128.20
(307)- second car= 131.19 (if you need to round this answer, it would be 131.2)
