A ratio stays equivalent when you multiply or divide the same thing to both numbers, just like fractions:

First of all, you can simplify it to

3:4 by dividing both numbers by 5.

Now you can multiply both numbers by 5 to get 75:100

<span>Finally, you can multiply both numbers by 3 to get the ratio 45:60</span>

Pls answer this with a picture showing the correct box plot

Answer/Step-by-step explanation:

To find out the mistake of the student, let's find the min, max, median, Q1 and Q3, which make up the 5 important values that are represented in a box plot.

Given, {2, 3, 5, 6, 10, 14, 15},

Minimum value = 2

Median = middle data point = 6

Q1 = 3 (the middle value of the lower part of the data set before the median)

Q3 = 14 (middle value of the upper part of the data set after the median)

Maximum value = 15

If we examine the diagram the student created, you will observe that he plotted the median wrongly. The median, which is represented by the vertical line that divides the box, ought to be at 6 NOT 10.

See the attachment below for the correct box plot.

Explain how to find the axis of symmetry for each function<br> h(x)<br> The graph goes under h(x)

AleksAgata [21]

Find the minimum point on the parabola, and take the x component of the coordinate. Then, put that number into this equation: x = (whatever the number was) so in this case the axis (or line) of symmetry is x = 1
