Mrs. Hall records the heights of 50 students in a spreadsheet. The mean height is 68 inches. After looking at the data again, she realized that two of the 50 observations were outliers that must have been typos, 82 and 86 inches. She deleted these two observations. What is the new mean, rounded to the nearest hundredth?

Answers

Answer 1

Answer:

The new mean of the heights of the students after the two outliers have been removed to the nearest hundredth is 67.33 inches.

What is the new mean?

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the heights / total students

Sum of the heights = 50 x 68 = 3400 inches

Sum of heights after the outliers are removed = 3400 - 82 - 86 = 3232

New mean = 3232 / 48 = 67.33 inches

Answer 2

Answer: Hello,

The new mean is (50*68-82-86)/66=48.969696...≈48.97

The equation D=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the substance. What happens to the density as the volume approaches 0?The density approaches infinity.
The density approaches 0.
The density approaches 1.
The density approaches 13.

Answers

D = 13/v

What happens to the density as the volume approaches 0?

The density approaches 13.

Assume : V = 3 ; V = 2 ; V = 1

D = 13/3 = 4.33
D = 13/2 = 6.50
D = 13/1 = 13

Answer:

Option A is correct

The density approaches infinity.

Step-by-step explanation:

Given the equation:

$D = (13)/(v)$ ....[1]

where,

D is density of a particular substance .

v is the volume of the substance.

We have to find What happens to the density as the volume approaches 0.

As the volume approaches to 0

⇒ $v \rightarrow 0$

[1] ⇒

$D \rightarrow \infty$

⇒The density approaches infinity.

Therefore, the density as the volume approaches 0 is, infinity.

Describe one way you could read the expression 0.50 x (24 + 8)

Answers

The value of the expression will be 16. Then the one way that you could read the expression by sixteen.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression is given below.

⇒ 0.50 x (24 + 8)

Simplify the expression, then the value of the expression will be

⇒ 0.50 x (24 + 8)

Apply the distribution property, then the expression is written as,

⇒ 0.50 x 24 + 0.50 x 8

Apply the multiplication property, then the expression can be written as,

⇒ 12 + 4

Apply the addition property, then the expression will be given as,

⇒ 16

The value of the expression will be 16. Then the one way that you could read the expression by sixteen.

More about the value of the expression link is given below.

Suppose Galileo and his assistant were 1 km apart when Galileo uncovered his lantern to try to measure the speed of light. How long would it have taken the light signal to reach his assistant?

Answers

There are many theories and measurement for the speed of light. It is believed that light travels at 299,792 km per second. In the earlier day philosopher Aristotle believed that light didn't travel but happens instantaneously. Therefore, for Galileo and his assistant to be only 1km apart, I would have to agree with Aristotle theory of light traveling instantaneously.
