Step-by-step explanation:
Step 1: Define Equation
8x - 3 = 2(x - 1/2)
Step 2: Solve for x
Distributive 2: 8x - 3 = 2x - 1Subtract 2x on both sides: 6x - 3 = -1Add 3 to both sides: 6x = 2Divide 6 on both sides: x = 1/3HELPPPP NOWWWW!!!!!A music teacher asked 23 students in the band how many hours they practiced playing their

Answer:
a. The data are skewed left, so most student's practice times are more than the mean practice time.
b. The data are skewed left, so most student's practice times are less than the mean practice time.
c. The data are skewed right, so most student's practice times are less than the mean practice time.
d. The data are skewed right, so most student's practice times are more than the mean practice time.
Answer:
The correct option is a.
The data are skewed left, so most student's practice times are more than the mean practice time.
Step-by-step explanation:
Refer to the attached box plot which shows number of hours the students spent on practice for playing their instrument each week.
When the data distribution is not symmetric around the mean then it is either skewed to right or skewed to left.
The given box plot is skewed to the left since the tail of the distribution on the left side is longer than the right side or in other words, most of the data is leaning to the right side of the curve.
Due to this, most student's practice times are more than the mean practice time.
A left skewed distribution is also known as negatively skewed distribution.
Therefore, we can conclude that the correct option is a.
a. The data are skewed left, so most student's practice times are more than the mean practice time.

What is the area of the triangle in the in the diagram?
Answer:
no tengo ni idea
Step-by-step explanation:
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).
The length of the base of the triangle will be given as,
Base = (x₂ - x₁)
The height of the triangle is given as,
Height = (y₂ - 0) or (y₁ - 0)
Height = y₂ or y₁
The area of the triangle will be given as,
A = (1/2) × (x₂ - x₁) × y₁
A = (1/2) y₁(x₂ - x₁)
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

my answer rounded up to 9%,sorry if it comes out wrong
I need you to do all plssss
Answer:
9 = probably D(maybe A)
I'm not sure what the answer is for #9 but I think it is most likely D. A is multiply 6 by 4 which would be substituting the value of w, for w. D is adding 2 to 40 which is combining like terms.

34% of 65. Do not round!!! pls help
Answer:
22.1
Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1

A chocolate cake and a vanilla cake were each cut into 12 slices. 5 slices of the chocolate cake were eaten and 7 slices of the vanilla cake were eaten. Was more of the chocolate cake or more of the vanilla cake eaten?
Answer: Vanilla
Step-by-step explanation:
The amount of chocolate cake remaining is;
= 12 - 5
= 7 slices
The amount of vanilla cake remaining is;
= 12 - 7
= 5 slices
More Vanilla cake was therefore eaten as less of it is left.
