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

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.
More about the area of the triangle link is given below.

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.
