Answers

Answer: 75% of 472 is 354

Step-by-step explanation: you can figure this out by dividing 354 by 3 = 118, then you multiply that 118 by 4 = 472.

The answer to this is 75% of 472 is 354
because you start by dividing 354 by 3 = 118, then you multiply that 118 by 4 = 472.

A population of caribou in a forest grows at a rate of 3% every year. If there are currently 208 caribou, which function represents the number of caribou in the forest in t years?

Answers

Answer:

f(x)=208^0.3x

Step-by-step explanation:

Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.

The generic formula fr an exponential equation is a^x.

A represents your initial value. In this case, its 208

x represents the growth. In this case, it's 0.3%.

Your equation should be f(x)=208^0.3x

Step-by-step explanation:

-6(x + 7) = -30

distribute the -6

-6 * x = -6x and -6 * 7 = -42

-6x - 42 = -30

add 42 to both sides

-6x = 12

divide both sides by -6

-6x/-6 = x and 12/-6 = -2

we're left with x = -2

Step-by-step explanation:

Hi!

It seems like you have two answers in the boxes already, but it is not correct.

Firstly, you cannot tell mean from a box plot. The first box should be moved to the last category.

Your second boxes seems to be correct though.

As far as the remaining boxes, I can help with those too!

Median: The median is identifiable in a box plot, as the line in the boxes themselves are the medians. The medians do line up, therefore they belong in category 1.

Minimum: This is the value that is the least. We can tell this from a box plot, by looking at the most left line, or the "whiskers", as some teachers call them. For our box plots, the minimum is 4. They line up exactly. Therefore, this box should go in the first category.

IQR: The IQR "measures the spread of the middle half of your data". In these box plots, the IQR is different. Therefore, it belongs in the second category.

Mode: This is the value that appears most often in a set of data values. You cannot tell this from a box plot. Therefore, it belongs in the last category.

I hope I could help!

Please plot this linear equation on a graph, and also explain how to plot it.
[tex]y=3x-7[/tex]

Answers

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day.

We can solve this equation in a single step, we just need a bit of theory and a graph.

We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.

This means that we know the following.

[tex]b[/tex] is the y coordinate of the y intercept.[tex]m[/tex] is the slope of the line.

Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).

Now that we've gotten that, we can start graphing.

The y intercept is -7 so we can plot (0,-7) as one of our points.

The slope of 3 means that we got up 3 units then right a single unit.

Therefore, another point could be (1,-4).

With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.

Cheers!

Answer:

Step-by-step explanation:

y = 3x - 7 is a linear equation with y-intercept -7 (or (0, -7) ) and slope 3. These two quantities are instantly readable from the equation.

There are several ways in which we may graph this equation. One is to plot the y-intercept (0, -7) Then choose an x-value, such as 3, and evaluate the function at that x value. We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2). Plot (3, 2) and then draw a line through the two plotted points.

Here's another way:

The slope here is 3, or 3/1, which represents rise / run. Plot (0, -7) as before.

Move your pencil from (0, -7) 1 space to the right and 7 spaces up. Then plot a new point at that location. Draw a line through (0, -7) and (1, 0).

Rafi had a board that was 15 1/2 feet long. He cut three pieces off the board that are each 3 7/8 feet long. How much of the board is left?

Answers

Answer:

Step-by-step explanation:

To answer this question, first we need to figure out how much of the board Rafi cut off.

To do this, we need to multiply the length of each piece by the number of pieces he cut off.

3 7/8 = 3.875

3.875 * 3 = 11.625

Now, because we knew Rafi cut off 11.625 feet off of the board, we just need to subtract this length from the length of the entire board to find the remaining length.

15 1/2 = 15.5

15.5 - 11.625 = 3.875

There is 3.875 feet or 3 7/8 of the board left.
