Variables are letters.

Constants are numbers without variables.

Coefficients are numbers with variables.

4t and 2st are coefficients.

16 is a constant

t and st are variables.

Best of Luck!

What is the range of possible

olya-2409 [2.1K]

Answer:

4<C <10

Step-by-step explanation:

Theorem: Given a triangle with sides A, B and C the sum of the lengths of any two sides of a triangle must be greater than the third side:

1. A+B>C

2. B +C >A

3. A+C>B

Thus given two sides of A=3 and B=7 C can be:

7 −3<C < 7+3

C range

4<C <10

Calculate the mean and median of each data set, and determine what type of distribution it has. Data Set 1 5 8 9 6 3 2 10 8 5 4

Bad White [126]

Answer:

Data Set 1:

Mean = 5.73

Median = 5

Data Set 2:

Mean = 5.34

Median = 5.64

Step-by-step explanation:

<u>To find the mean, you need to add up all the data, and then divide this total by the number of values in the data.</u>

<u>Data Set 1:</u>

5 + 8 + 9 + 6 + 3 + 2 + 10 + 8 + 5 + 4 + 3 = 63

There are 11 values, so you divide the total by 11:

63 ÷ 11 = 5.7272.. ≈ 5.73

<u>Data Set 2:</u>

8 + 7 + 3 + 2 + 4 + 6 + 2 + 7 + 4 + 9 + 6 + 5 + 5.27 + 6 + 5.73 + 5.55 = 85.55

There are 16 values, so you divide the total by 16:

85.55 ÷ 16 = 5.34

<h3>The Median:</h3>

<u>To find the median, you need to put the values in order, then find the middle value. If there are two values in the middle then you find the mean of these two values.</u><u> </u>

<u>Data Set 1:</u>

The numbers in order:

2, 3, 3, 4, 5, (5), 6, 8, 8, 9, 10

The middle value is marked in brackets, and it is 5.

So the median is 5

<u>Data Set 2:</u>

2, 2, 3, 4, 4, 5, 5.27, (5.55, 5.73), 6, 6, 6, 7, 7, 8, 9

This time there are two values in the middle. They have been in brackets The median is found by calculating the mean of these two values:

(5.55 + 5.73) ÷ 2 = 5.64

So, the median is 5.64

What is the slope-intercept form of the function that contains the point (–1, 5) and has a slope of –4?

katovenus [111]

If it has a slope of -4, you need to find b.

So you want to plug in your coordinate values for x and y to solve.

5=-4(-1)+b

5=4+b you then subtract 4 from both sides to find the answer for b.

1=b

So your equation would be:

y=-4x+1

How do you tell the base and height of a triangle?

Wittaler [7]

Answer:

In triangles

In the case of a triangle, a common way to calculate its area is 'half of base times height' where the 'height' is the altitude, or the perpendicular distance from the base to the opposite vertex. The base can be any side, not just the one drawn at the bottom.

Step-by-step explanation:
