1. This is one confusing question... But here is what I did
x = 2y + 1
y = 3y^{2} + 2x

So plug in Y to solve for X
x = 2 (3y^{2} + 2x) + 1
x = -2y^{2} - \frac{1}{3}
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...


5. You have to find the multiples of 60 so...

1 60
2 30
3 20
4 15
<span>5 12  <---

Calculate the volume of the following object:
frozen [14]

Answer:

262.44 cubic metres.

Step-by-step explanation:

First, we can calculate the volume of the cylinder by doing pi * r^2 * h. In this case, r is 5 / 2 and h is 7.

pi * (5/2)^2 * 7 = pi * 25/4 * 7 = pi * 6.25 * 7 = pi * 43.75 = 3.14159265 * 43.75 = 137.4446784 cubic m.

Seconds, we calculate the volume of the cube. It is 5^3 = 5 * 5 * 5 = 25 * 5 = 125 cubic m.

137.4446784 + 125 = 262.4446784, which is about 262.44 cubic metres.

Hope this helps!

ella [17]

The completion of the grouped frequency distribution for the test scores of the fifteen students that took the biology test last week is as follows:

Test scores     Frequency

79 to 83                 5

84 to 88                 2

89 to 93                 6

94 to 98                 2

<h3>What is a frequency distribution?</h3>

A frequency distribution is a pictorial or graphical representation that shows the number of observations of each categorical value (a group of values) that occurs.

By showing the frequency counts for each category, it becomes easier to determine and interpret the presented information based on their relative frequencies.

Frequency charts, tables, or graphs are used to display frequency distributions of data.
