Angle 1 and 4: 78 degrees- on one side of these angles (the line the seperates it running parallel) the angles total to 180 degrees, we take angle 3 which was 24 and subtract that from 180. That equals 156 which we then divide into two because we have two angles left to solve for which makes 78 each.
Angle 2: 71 degrees- We know angle 3 is 24 and we have a written angle as 85. Knowing each side of these angles equals 180 degrees, we add 85 and 24 to get 109. We then will subtract 180 from 109 to get our missing angle which is 71 degrees.
I hope I could help :)

Answer:
X = 13
Step-by-step explanation:
Since this is a linear pair, it equals to 180 degrees.
7x + 37 + 4x = 180
11x + 37 = 180
-37 -37
11x = 143
11x/11 = 143/11

Is the probability of Janessa winning an independent event or dependent event? Why?
O) Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
O) Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.

A sample of 144 was taken from a population with a standard deviation of 36
inches. What is the margin of error for a 68% confidence interval?
A. 9
B. 6
C. 3
D. 12
Answers
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches

The probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.
What is probability?Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes.
Probability is a measure of how likely an event is going to happen.
Given is to find the probability that a point randomly chosen in the large triangle is also in Region A.
We can find the area of region A as -
Area{A} = A{Rectangle} + A{Right triangle}
Area{A} = (Length x Breadth) + (1/2 x base x height)
Area{A} = (5 x 2) + (1/2 x 1 x 2)
Area{A} = 10 + 1
Area{A} = 11 square units
Total area of the region {A + B} as -
Total Area{A + B} = 11 + (1/2 x 10 x 5)
Total Area{A + B} = 11 + 25
Total Area{A + B} = 36 square units
The probability that a point randomly chosen in the large triangle is also in Region A will be -
P{A} = (Area{A}/Total Area{A + B})
P(A) = 11/36
Therefore, the probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

Lara is playing a video game where she hunts for treasure, like these gems:
A sapphire is worth 5 gold coins, and a ruby is worth 8 gold coins.
On her last hunt, Lara found 17 gems, all either rubies or sapphires, and sold them for 100 coins. How many sapphires did she find?
Answers
Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.

All i need to know is if its a function or not (I will give branliest for a good explanation)
Answers
Answer:
It's fine. It is a function. The language can be very convoluted. Put simply a domain value cannot have 2 different range values.
Step-by-step explanation:
The confusing part I think, is probably the fact that -1 and 1 both have an answer of 5.
That's fine. Parabolas do that and they are functions. Two different xs can have the same value. The thing that eliminates functions is when the x value (the domain) has two different y values (the range values). Then you don't have a function.
To try and make it clearer if 1 pointed at both 3 and 5 you would not have a function.

Answers
Answer: 0.093 chance
Step-by-step explanation:
23 black + 32 blue + 8 white = 63 total
FIRST MARBLE IS BLUE:
32/63
SECOND MARBLE IS BLACK:
23/62
LAST MARBLE IS NOT BLUE:
30/61
MATH:
32/63*23/62*31/61 = 0.093
sorry if it’s wrong but I think it’s right
Answer:
.093
Step-by-step explanation:
There are 63 marbles in the jar
P(pick a blue) = 32/63
Since you are not replacing that marble, so there are 62 marbles in the jar, 31 blue, 23 black, 8 white
P(pick a black) = 23/62
Now there are 61 marbles in the jar. 22 black, 31 blue and 8 white
P(not a blue) = 30/61
P(blue, black, not blue) = (32/63)(23/62)(30/61)
= .093

How many combinations of 3 playing cards (from a 52-card deck) exist?
Answers
Answer:

Step-by-step explanation:
pls trust me i just took the test
The number of combination of 3 playing cards from 52 card deck is 22100.
What is Combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
Here, total cards = 52
cards to be selected = 3
So, total possible combination = ⁵²C₃
= (52 X 51 X 50) / (3 X 2 X 1)
= 22100
Thus, the number of combination of 3 playing cards from 52 card deck is 22100.

Find the mean, median, and mode(s) of the data with and without the outlier.
45, 52, 17, 63, 57, 42, 54, 58
Answers
Answer:
Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17
Step-by-step explanation:
Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)
Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right... until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).
Mode: Is the number that shows up the most. In this case none of them do.
Outlier: The number that is farthest from the other numbers (17).
The mean, median, and mode(s) of the data Without outlier Mean is 51
Median is 53 and Mode is None
To find the mean, median, and mode(s) of the data, we can start by arranging the numbers in order from smallest to largest:
17, 42, 45, 52, 54, 57, 58, 63
The mean is the sum of all the numbers divided by the total number of numbers.
If we remove the outlier (17), the data set becomes:
42, 45, 52, 54, 57, 58, 63
Mean:
Mean = (42 + 45 + 52 + 54 + 57 + 58 + 63) / 7 = 51
Median:
Median = (52 + 54) / 2 = 53
There is no mode in this set since no number appears more than once.
