If 6x + 5y = 10, what is y in terms of x?<br> Please include an explanation!

Mnenie [13.5K]

what you're trying to do is form an equation for y

6x + 5y = 10

5y = -6x + 10 we need y to be singular so divide by numeral before y

y = - 6x/5 + 10/5

y = - 6x/5 + 2

This graph relates the volumes of triangular pyramids with a base area of 12 square inches and their heights.

Nikolay [14]

Answer:

$V=40\ in^3$

Step-by-step explanation:

The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula

$V=\frac{1}{3}Bh$

where

B is the area of the triangular face

h is the height of the pyramid

we have

$B=12\ in^2\\h=10\ in$

substitute the given values

$V=\frac{1}{3}(12)(10)=40\ in^3$

Student Debt – Vermont: The average student loan debt of a U.S. college student at the end of 4 years of college is estimated to

mezya [45]

Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, $\mu$ = $23,500

Sample mean, $\bar{x}$ = $24,500

Sample standard deviation,s = $2,800

Sample size, n = 146

Confidence interval:

$\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436$

$24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)$

The confidence interval is (24116.3878,24883.6122).
