Step-by-step explanation:
Together they spent a mean price of $40 on 8 sweaters. The first 7 sweaters cost $50, $55, $30, $35, $39, $40 and $42. How much, in dollars, does the 8th sweater cost?
If the mean price is $40, 8 x 40 = the total price, = 320
Add up what we knew they spent:
50 + 55 + 30 + 35 + 39 + 40 + 42 = 291
The difference between those 2 numbers is the price of the 8th sweater
320 - 291 = 29

There are 10 ice cream sandwiches, 5 drumsticks, and 6 vanilla ice cream cups in the freezer. You randomly select one and give it to your sister, then randomly select one for yourself. What is the probability of NOT selecting a drumstick and a vanilla ice cream cup? *
Answers
Answer:
The probability of not selecting a drumstick and a vanilla ice cream cup is 92.86%.
Step-by-step explanation:
Since there are 10 ice cream sandwiches, 5 drumsticks, and 6 vanilla ice cream cups in the freezer, and I randomly select one and give it to my sister, and then randomly select one for me, to determine what is the probability of not Selecting a drumstick and a vanilla ice cream cup, the following calculation should be performed:
5/21 x 6/20 = X
0.2380 x 0.3 = X
0.0714 = X
1- 0.0714 = X
0.9286 = X
0.9286 x 100 = 92.86
Therefore, the probability of not selecting a drumstick and a vanilla ice cream cup is 92.86%.

Whitney is buying a house next year. She applies for a $200,000 loan to be paid in 30 years. Her credit score is 575. Using the table, how much bigger will her monthly payment be than if her score were 850?
$99.00
$680.00
$160.00
$365.00
Answers
Answer:
Because here score is 575 she must pay 2365 per mo according to the table
If her score were 850 she would pay 1685 per month
So the difference in the two rates is:
2365 - 1685 = 680 a month more because of the low credit score

Choose the algebraic description that maps the image ΔXYZ onto ΔX′Y′Z′. Question options: A)
(x, y) → (x + 6, y – 1)
B)
(x, y) → (x – 5, y – 1)
C)
(x, y) → (x + 5, y – 1)
D)
(x, y) → (x – 6, y – 1)
Answers
Answer:
D
Step-by-step explanation:
To get from ΔXYZ (the figure on the right) to ΔX′Y′Z′ (the figure on the left), each point is translated left 6 units and down 1.
Movement left and right is related to the x-axis. So moving 6 units left (in a negative direction) is x - 6.
Movement up and down is related to the y-axis. So going down (in the negative direction) is y - 1.

Answers
Answer:
4/9
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Probability the number is less than 10 = total numbers less than 10 / sum of numbers

What would x=? Alternate Exterior & Interior Angles, 8th grade math! Help would be appreciated <3
Answers
Answer:
x = 4
Step-by-step explanation:
From the picture attached,
Two parallel lines with a transversal line intersecting these parallel lines at two distinct points.
Angles measuring 36° and (8x + 4)° are Alternate interior angles.
Therefore, measure of these angles will be equal.
(8x + 4)° = 36°
(8x + 4) - 4 = 36 - 4
8x = 32
x = 4

What’s the value of x?
Answers
Answer:
Step-by-step explanation:
Simplifying
7x = -3x + -60
Reorder the terms:
7x = -60 + -3x
Solving
7x = -60 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
7x + 3x = -60 + -3x + 3x
Combine like terms: 7x + 3x = 10x
10x = -60 + -3x + 3x
Combine like terms: -3x + 3x = 0
10x = -60 + 0
10x = -60
Divide each side by '10'.
x = -6
Simplifying
x = -6

How do you do rise over run
Answers
Answer:
Rise over Run is another term for the slope
Step-by-step explanation:
to find the slope, (y2 - y1)/(x2 - x1)
Answer:
If you look at a graph, you see 2 lines forming a "plus" shape. The horizontal line is called the x-axis, and the verticle line is called the y-axis. Rise over run is how much the y changes when the x changes. So if the graph increases its y value by 2 each time the x increases by 1, then rise over run is 2.
An air traffic controller at an airport sights a plane at an angle of elevation of 28º.
The pilot reports that the plane's altitude is 4500 feet.
To the nearest foot, what is the distance from the control tower to the plane?
3190 ft
8463 ft
2113 ft
9585 ft
Answers
Answer:
8463 feets
Step-by-step explanation:
Using the diagram attached :
Distance of control tower to plane = d
Using tro:
Tan θ = opposite / Adjacent
Tan 28 = 4500 / d
0.5317094 = 4500 / d
0.5317094d = 4500
d = 4500 / 0.5317094
d = 8463.2690

In a board game, students draw a number do not replace it, and then draw a second number. Determine the probability of each event occurring. Drawing an odd number then drawing a 6? dependent events. PLEASE HELP ME
Answers
The figure depicting the board game is attached below.
Answer:
Step-by-step explanation:
Kindly note that selections done without replacement.
Count of numbers on the board game = 8
Count of odd numbers = (1, 9, 1) = 3
Count of digit 6 = 3
Probability = required outcome / Total possible outcomes
P(picking an odd number) = 3 / 8
Without replacement
Numbers left on board game = 8 - 1 = 7
P(picking a 6) = 3 / 7
Hence,
P(picking an odd number then, a 6) = 3/8 * 3/7 = 9 / 56
Why would the polynomial, "[tex]x^2+5x-24[/tex]" factor out to (x-3)(x+8)?
Answers
Step-by-step explanation:
5x can also be written as " -3x + 8x " so:
[tex]x^2+5x-24 = x^2-3x+8x-24[/tex]
Using the distributive property:
[tex]x(x-3)+8(x-3)[/tex]
Then again, using the distributive property (but in reverse):
[tex](x-3)(x+8)[/tex]
The two numbers that the middle term should be split into in order to factor can be found by listing out pairs of factors for the product of the last term and the coefficient of the first term, and using the two factors whose sum is the middle term.
For eg (because that was a bit text heavy):
The product of the last term and the first coefficient (1 * (-24)) is -24
the factors of -24 include (and their sum)
-1, 24 (23)
1, -24 (-23)
-2, 12 (10)
2, -12 (-10)
-3, 8 (5)
3, -8 (-5)
-4, 6 (2)
4, -6 (-2)
The middle coefficient is 5 and the sum of the factors -3 and 8 are 5, so split 5x into -3x + 8x to be able to factor how I showed before.

Hana is playing a virtual reality game in which she must toss a disc to land on the largest triangular section of the board. If the disc is equally likely to land anywhere on the board, what is the probability that she will succeed? Explain
Answers
Answer:
Her probability of success is 1/2
Step-by-step explanation:
Firstly, we have to calculate the area of the entire board
That would be the rectangle of the measure 50 cm by 40 cm
We have the area as the product of this two
That would be 50 * 40 = 2,000 cm^2
Now, the value calculated is the area of the entire possible landing area
Secondly, we need to get the area that counts as a success
that would be the area of the triangle that has a base of 50 cm and a height of 40 cm
The area of this is the product of the two divided by 2
we have this as ;
50 * 40 * 1/2 = 1,000 cm^2
So, her probability of success is simply the area of the triangle divided by the area of the rectangle
= 1000/2000 = 1/2
