The Number Of Writing Instruments In Some Teachers' Desks Is Displayed In The Dot Plot. Which Is Greater

Answers

Answer 1

The median is greater than the mean. From the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean.

In the given chart we can deduce the following;

number of instruments that is 5 = 1number of instruments that is 6 = 1number of instruments that is 7 = 1number of instruments that is 8 = 1number of instruments that is 9 = 3number of instruments that is 10 = 4number of instruments that is 11 = 2number of instruments that is 12 = 1

These numbers can be listed as follows;

5, 6, 7, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 12

The median of these numbers is calculated as;

[tex]median = \frac{9+ 10}{2} = 9.5[/tex]

The mean of these numbers is calculated as;

[tex]mean = \frac{5+6+7+8+9+9+9+10+10+10+10+11+11+12}{14} = 9.07[/tex]

Thus, the median is greater than the mean.

Also, from the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean. But if the distribution is skewed to the right, the mean is always greater than the median.

A: P = 2L + 2W solve for W

B: C = 5/9(F - 32) solve for F​

Answers

Answer:

A. P/2 - L = W

B. 9/5C + 32 = F

Step-by-step explanation:

A. P = 2L + 2W

P = 2(L+W)

P/2 = L + W

(P/2)-L = W

B. C = 5/9(F - 32)

9/5C = F - 32

9/5C + 32 = F

What is the equation of the line that is parallel to the line y =1/3 x + 4 and passes through the point (6, 5)?

Answers

Answer:

y = [tex]\frac{1}{3}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 4 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Parallel lines have equal slopes , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute (6, 5) into the partial equation

5 = 2 + c ⇒ c = 5 - 2 = 3

y = [tex]\frac{1}{3}[/tex] x + 3 ← equation of parallel line

What is tangent of an angle?

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal to zero.

Given is a right triangle ABC, with sides AB = 26, BC = 24, AC = 10

We are asked to find the value of tangent of angle A,

We know that, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Therefore,

Tan A = BC / AC = 24/10 = 12/5

Hence, the value of tan A in triangle ABC is 12/5

Calculate the distance between the points F=(-2,1) and A=(4,-2) in the coordinate plane. Round your answer to the nearest hundredth

Answers

Answer:

The distance between F and A is approximately 6.71 units.

Step-by-step explanation:

To find the distance between any two points, we can consider using the distance formula. Recall that:

[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Let F(-2, 1) be (x₁, y₁) and A(4, -2) be (x₂, y₂).

Substitute and evaluate:

[tex]\displaystyle \begin{aligned} FA &= \sqrt{((4) - (-2))^2 + ((-2) - (1)^2} \\ \\&=\sqrt{(6)^2 + (-3)^2} \\ \\&=\sqrt{36 + 9} \\ \\ &= \sqrt{45} \\ \\ &= 3\sqrt{5}\\ \\&\approx 6.71\text{ units} \end{aligned}[/tex]

In conclusion, the distance between F and A is approximately 6.71 units.
