Camille's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and r

egression line below show the relationship between how many hours students spent studying and their score on the test.
The fitted line has a yyy-intercept of 373737.
What is the best interpretation of this yyy-intercept?

(Choice A)
A
The model predicts that the study time will increase 373737 hours for each additional point scored.

(Choice B)
B
The model predicts that the score will increase 373737 points for each additional hour of study time.

(Choice C)
C
The model predicts that a student who scored 000 points studied for 373737 hours.

(Choice D)
D
The model predicts that students who didn't study at all will have an average score of 373737 points.
A graph plots Score, from 0 to 90, in increments of 10, versus Study time, in hours, from 0 to 4.5, in increments of 0.5, on an x y plane. Dozens of points rise diagonally in a tight, narrow cluster between (1.8, 62) and (4.4, 95). A regression line rises diagonally through the center of the cluster from (0, 38) to (4.2, 100). All values estimated.

My new Labrador puppy weighs 3 pounds more than 0.25 of his mom's weight His mom weighs 60 pounds what is kaiser weight?
Delicious77 [7]
Ok, first you have to know that 0.25 is one fourth. Finding one fourth of 60 is the first step. 1/4 of 60 is 15. Now, add 3 to 15, and you have your answer! The answer is 18 pounds.

According to the Rational Root Theorem, the following are potential roots of f(x) = 60x2 – 57x – 18. Which is an actual root of
emmainna [20.7K]

Answer: The correct option is third, i.e., -\frac{1}{4}.

Explanation:

The given function is,

f(x)=60x^2-57x-18

The Rational Root Theorem states that the rational roots are in the form of,

r=\frac{\text{factors of constant term}}{\text{factor of leading coefficient}}

These rational roots are possible rational roots not the actual roots of f(x).

For actual roots of f(x), the value of the function is 0.

Put each value of x from the option in the function, if we get the value of f(x) is 0, then that value is the actual root of f(x).

Put x=3.

f(3)=60(3)^2-57(3)-18=351\neq 0

Put x=6

f(6)=60(6)^2-57(6)-18=1800\neq 0

Put x=-\frac{1}{4}

f(-\frac{1}{4})=60(-\frac{1}{4})^2-57(-\frac{1}{4})-18=0

Put x=-\frac{6}{5}

f(-\frac{6}{5})=60(-\frac{6}{5})^2-57(-\frac{6}{5})-18=136.8\neq 0

Only for x=-\frac{1}{4} the value of function is 0, therefore the correct option is third.

Evaluate the expression for y=3.8, y=5, and y=5.6.<br> y=4
Vaselesa [24]

Answer:(a) x - 0.7 = 1.5

Step-by-step explanation:

Determine whether each of the following is a solution of x − 0.7 = 1.5: (a) x = 1 (b) x = −0.8 (c) x = 2. Step 1. Substitute the number for the variable in the equation.

Step 2. Simplify the expressions on both sides of the equation.

Step 3. Determine whether the resulting equation is true.

If so, the number is a solution.

If not, the number is not a solution.
