Answer:

Without any studying, the score would be about 328

Step-by-step explanation:

The y-intercept of an equation represents the point where its graph crosses the y-axis. At this point the value of x is always equal to 0.

The y-intercept of the equation in this context would represent the Math SAT score of a student who did not do any studying, that is the number of hours spent studying, x = 0.

Substitute x = 0 in the given equation and solve for y;

y = 24.387(0) + 328.182

y = 328.182

Therefore, Without any studying, the score would be about 328

What is the answer to this question

iren2701 [21]

Answer:

Step-by-step explanation:

The integral decomposes into the sum ...

$\displaystyle\int_{-2}^2{\left(x^3\cos{\dfrac{x}{2}}\right)\sqrt{4-x^2}}\, dx+\dfrac{1}{2}\int_{-2}^2{\sqrt{4-x^2}}\, dx$

The first term of this sum is the integral of an odd function, so is zero. The second term of this sum is 1/2 the area under a semicircle of radius 2, so is ...

A = (1/2)(1/2)π·2² = π

The value of the integral is π.

The sum of three times a number and 2 less than 4 times that same number is 15. Which of the following equations could be used t

Ket [755]

3n + (4n - 2) = 15

is how this equation would be displayed.

Now let's solve for x.

We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.

3n + 4n - 2 = 15

Combine like terms.

7n - 2 = 15

Add 2 to both sides.

7n = 17

Divide both sides by 7.

n = 17/7
