Answer:
<h3>
This shows that the height of the red prism will be three times that of blue</h3>
Step-by-step explanation:
Volume of a prism = 1/3 * base area * height
V = 1/3Bh
Vr = 1/3Brhr...1
Vb = 1/3Bbhb... 2
Let the volume of red prism be Vr and the volume of blue prism be Vb. If both prisms have the same volume then Vr = Vb = V.
Also if the area of the base of the red prism is one third that of the blue prism, the B, then Br = 1/3 Bb where Bb = 3Br..(3)
Since the volume are the same then;
1/3Brhr = 1/3Bbhb
Substituting equation 3 intio the resulting expression;
1/3Brhr = 1/3(3Br)hb
hr = 3hb
This shows that the height of the red prism will be three times that of blue
There are an infinite number of such subsets. One of them is the set of real numbers in the interval (7, 8). Perhaps you're thinking "irrational" numbers, as opposed to "integers" or "rational" numbers.
The amount of variance for y that is predicted by its relationship with x is 64%.
<h3>
How much variance is predicted?</h3>
Variance measures the rate of dispersion of a data point around the dataset. It can be calculated by finding the square of the standard deviation of a dataset. Variance measures the variation of a data set.
Correlation is a statistical measure used to measure the linear relationship that exists between two variables. The greater the correlation coefficient is closer to one, the greater the linear relationship that exists between the two variables. A positive correlation occurs when the two variables move in the same direction.
Variance = (correlation coefficient²) x 100
(0.80²) x 100
0.64 x 100 = 64%

The answer to your problem is C
B.)
Because 4x^2 has no other like term.
Then x/2+x= 3/2x
Finally, -4+-3= -7
You just combine them together to form an equation:)
