A square piece of plywood has sides that are 10 feet long. What is the piece of plywood's area

Answers

I don’t really understand the question, but if you’re looking for the area, it would be 100 feet since you have to do “Side x Side”. Hope this helps!

Answer:

100ft^2

Step-by-step explanation:

The area of a square is always one of the side's length multiplied by itself.

10 x 10 = 100ft^2

Help!!!! I don’t really understand sloped so any help would be helpful.

Answers

Answer: The slope is -2.

Step-by-step explanation:

Since the line is going through the origin it means that if you find a point on the line and divided the y coordinate of point by it's x coordinate then you will get the slope or the constant change value.

The equation of a proportional line says that  y = kx  where k is the slope.

And to find k, you will divide y by x.

One point that is located on the line is  (-1,2)  The y coordinate is 2 and the x coordinate is -1.

Divide 2 by -1 to find the slope.

2/-1= -2  

This means the slope is -2.

Answer:

The slope is [tex]\frac{3}{2}[/tex]

The y-intercept is 9

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

m is the slope of the line whose rule is [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept, you can find it by substituting x, y in the equation by (x1, y1) OR (x2, y2)

Let us solve the question:

Choose any two-point from the table

∵ The line passes through the points (2, 12) and (4, 15)

∴ x1 = 2 and x2 = 4

∴ y1 = 12 and y2 = 15

→ Use the rule of m to find it

∵ [tex]m=\frac{15-12}{4-2}=\frac{3}{2}[/tex]

∴ m = [tex]\frac{3}{2}[/tex]

∴ The slope is [tex]\frac{3}{2}[/tex]

→ Substitute its value in the form of the equation above

∴ y = [tex]\frac{3}{2}[/tex] x + b

→ To find b substitute x and y by x1 and y1

∴ 12 = [tex]\frac{3}{2}[/tex] (2) + b

∴ 12 = 3 + b

→ Subtract 3 from both sides

∴ 12 -3 = 3 - 3 + b

∴ 9 = b

The y-intercept is 9

In Mr. Britt's class the distribution of ages of his students has a mean of 115 months and a standard
deviation of 3.6 months.

If no students leave or join the class, what will be the mean and standard deviation of the distribution of
student's ages 4 months later?

Answers

Using statistical concepts, it is found that the mean will be of 119 months, while the standard deviation will be of 3.6 months, given by option C.

-------------------------------------

The mean of a data-set is the sum of all values divided by the number of values.The standard deviation is the square root of the sum of the difference squared of each observation and the mean, divided by the number of values.If x is added to all values of a data-set, it is also added to the mean, while the standard deviation remains constant.

-------------------------------------

Mean of 115 months and standard deviation of 3.6 months.4 months later is the same as adding 4 to each observation.Thus, the mean will be of 115 + 4 = 119 months, while the standard deviation remains constant at 3.6 months.

Absolute value is the distance between the number and 0. Since distance cannot be negative, the absolute value of something is always going to be positive. In this equation | x | = 12 since 12 is already a postive number and the distance between 12 and 0 is 12, this means that x is equal to 12.

In a sequence of numbers, a3=0, a4=4, a5=8, a6=12, and a7=16. Based on this information, which equation can be used to find the nth term in the sequence, an?

Answers

Answer: aₙ = -12 + 4*n

Step-by-step explanation:

We know that:

a₃ = 0

a₄ = 4

a₅ = 8

a₆ = 12

a₇ = 16

This seems to be an arithmetic sequence.

To test this, we need to calculate the difference between any two consecutive terms in the sequence, and this must be a constant for any pair that we choose.

a₄ - a₃ = 4 - 0 = 4

a₅ - a₄ = 8 - 4 = 4

a₆ - a₅ = 12 - 8 = 4

etc

we can conclude that this is an arithmetic sequence.

The n-th term in an arithmetic sequence, where the increase between consecutive terms is 4, is:

aₙ = aₙ₋₁ + 4.

Another way is:

aₙ = a₀ + n*4.

Where to find a₀, we can start with the value that we know and go back:

a₂ = a₃ - 4 = -4

a₁ = a₂ - 4 = -8

a₀ = a₁ - 4 = -12

Then the n-th term can be written as:

aₙ = -12 + 4*n
