Answer:
a. (5x+75)°
b. x = 21
c. X° = 21° and (4x+75)°= 159°
Step-by-step explanation:
A. Combine like integers.
B. (5x+75)°=180° Because they are suplementary angles.
5x°= 105°
5x ÷5 = 105 ÷ 5
x = 21
C. (4x + 75)°
4(21) + 75
84 + 75 = 159°

Answer:
Mean: 86
Meadian: 85
Mode: 85

Mean: Add up all numbers and divide by 9
Median: Count a number twice such as 85, add 85+85 and divide by 2
Mode: Most occuring number. 85 is the mode.
Data are collected about the amount of time, in minutes, each member of the lacrosse team spends practicing. How does a single outlier change the mean of the collected data?
A single outlier causes the value of the mean to move slightly toward the outlier.
A single outlier causes the value of the mean to move slightly away from the outlier.
A single outlier does not affect the value of the mean.
A single outlier doubles the value of the mean.

Brent plays three sports: basketball, baseball, and soccer. He calculated the mean absolute deviation of the points he scored in each season.
basketball: mean absolute deviation of 4.6
baseball: mean absolute deviation of 3.5
soccer: mean absolute deviation of 1.2
In which sport were his scores the most spread out?
soccer
basketball
baseball
Answer:
basketball
Step-by-step explanation:
i took the test :)
Basketball have most spread out.
Option B is correct.
What is Standard Deviation?A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.
We have
Basketball: mean absolute deviation of 4.6
Baseball: mean absolute deviation of 3.5
Soccer: mean absolute deviation of 1.2
As, a high mean absolute deviation tells us that many of the data values are spread out further from the mean.
Here Basketball have highest absolute deviation.
Thus, Basketball have most spread out.

Jaylah started with $200 in her savings account to go to Disneyland. She wanted to increase her savings so she started babysitting. She earns $10 an hour and deposits it in her savings account. What is Jaylah's initial value and rate of change?
Answer:
Initial Value= $200, Rate of Change= $10 per hour (or just $10)
Step-by-step explanation:
The initial value is what Jaylah started with, and in this case, she starts with $200.
The rate of change is how much Jaylah earns, in this case per hour. It says that she earns $10 an hour, so the rate of change is $10.
For each ordered pair,solve the percent problems to find the corridinates (x% of 31 is 3.317,4.407 is 39% of y)
Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y
4407 × 100/39=y

A dart is thrown at the board 100 times at random.
About how many times is it likely to land in the shaded area?
The number of times that it is likely to land in the shaded area will be 40 times out of 100 times.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
A dart is thrown at the board 100 times at random.
The number of times that dart hit the board is 40 times. Then the probability is calculated as,
P = 40 / 100
P = 2/5
P = 0.40 or 40%

Answer:
Radius: about 1.42 mm
Step-by-step explanation:
First, you divide the circumference (8.9) by 3.14, or π.
Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)
Diameter (2.83439490446) divided by 2 = radius (1.41719745223)
Now, you have to round to the nearest hundredth.
1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

What is the surface area of the Triangular Prism rounded to the nearest tenth?
A)18.5
B) 36.9
C) 43.6
D) 87.2
Answer:
C. 43.6
Step-by-step explanation:
you need to take the area of each shape
lets do the skinny triangles first on the top and bottom of this shape.
so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3
because the formula of a triangle is half the base times height.
so we get 0.5 * 1.26 * 5.3 = 3.339
multiply it by two and we get 6.678
now lets find the area of the huge rectangle on the back/behind of the shape
3.3*5.3 = 17.49
now lets find the area of the two smaller rectangles
3.3 * 3.6 = 11.88
2.3 * 3.3 = 7.59
now lets add
6.678 + 17.49 + 11.88 + 7.59 = 43.638
round it to 43.6
