Answer:
I'm going to assume that the binder is $10, and that the tax is applied after the 60% off, in which case the answer is $4.24
Step-by-step explanation:
10 * 10 = 100
6 * 10 = 60
10 - 6 = 4
6 / 25 = 0.24
4 + 0.24 = 4.24
Answer: $4.24

A parabola is open up if a > 0.
The vertex formula:

(h; k) - the coordinates of the vertex

Therefore h = -5 < 0
Answer: B. y = x² + 10x + 24.
The second i think you did good
I don't understand. What are the values given? Are they values of an x,y plot?
If you plot them they are a straight line with y =6x - 2.9 but I don't know what you mean by when x=3 and y = 4?
Using the concepts of the mean and of the median, it is found that the correct option is given by:
both in the interval 6–10.
<h3>What are the mean and the median of the data-set?</h3>
- The mean is the <u>sum of all observations divided by the number of observations</u>.
- The median is the measure that separates the bottom half of the variable from the upper half, that is, the 50th percentile.
To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:

The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.
Hence, the correct option is given by:
both in the interval 6–10.
