Answer:

b

Step-by-step explanation:

Because the population is too large and it would be impractical to survey the whole population, a sample of the population is chosen to take part in the survey. This sample is taken as been representative of the whole population

Based on the sample, the fraction of students that speak more than one language fluently = 15/90= 0.166667

Population that would speak more than one language fluently = 0.166667 x 1800 = 300

Your problem is:
$35.00 is what percentage of $437.50?

If you are given a part and the whole, and you want to know what percent the part is of the whole, divide the part by the whole and multiply by 100.

In this case, the whole is $437.50.
The part is $35.00.

35/437.5 * 100 = 8%

Find an equation of the line described. Store the equation in slop-intercept form when possible.
Finger [1]

Answer:

Y = -5

Step-by-step explanation:

The line needs to be parallel to the y-axis, which means it forms a 90° angle with the y-axis. This means the line we are looking for is a straight horizontal line. The line must pass through the point (-7, -5), but we can disregard the x value since we figured out that the line is perfecly horizontal, so it has no x value. The answer we are left with is y = -5, which is a horizontal line across -5 on the y axis.

Hopefully you can understand my explanation :)

A. When x= -1, what is the value of y?
Pachacha [2.7K]

Answer:

When x=-1, y=3; when y=7, x=1; the y-intercept is 5; the x-intercept is 2.5; the slope is 2; the lines' equation is y=2x+5

Step-by-step explanation:

The first two answers can be easily interpreted by looking at the graph. For the next two, remember, the x-intercept is the point where the line touches the x-axis and the y-intercept is the point where the line touches the y-axis. For question e, the slope can be calculated by plugging the two coordinates from the first two questions, (-1,3) and (1,7), into the formula \frac{y_2 - y_1}{x_2-x_1} or by using the graph to count the slope. The equation of the line is written in slope-intercept form, y=mx+b. Here, m is the slope and b is the y-intercept. Plug in these values that you already found while answering the previous questions and you have the answer.
