Use cubic regression to find a
function that fits the following
points.
(1,-1), (2,-13), (3,-45),(-1,11)
y = [?]x3+[ ]x2+0 ]x+[ ]
The cubic regression function of the points (1,-1), (2,-13), (3,-45), (-1,11) is y = -2x³ + 2x² - 4x + 3
How to determine the function?The points are given as:
(x,y) = (1,-1), (2,-13), (3,-45), (-1,11)
A cubic regression function is represented as:
y = ax³ + bx² + cx + d
Next, we determine the cubic function using a graphing calculator.
From the graphing calculator, we have the following coefficients:
a = -2b = 2c = -4d = 3Recall that:
y = ax³ + bx² + cx + d
So, we have:
y = -2x³ + 2x² - 4x + 3
Hence, the cubic regression function of the points is y = -2x³ + 2x² - 4x + 3

f p(x) = 2x2 – 4x and q(x) = x – 3, what is (p circle q) (x)
Answer:
[tex]2x^{2} - 16x + 30[/tex]
Step-by-step explanation:
Here we have to find p(q(x))
q(x) =x -3
we will plug value of q(x) in x of p(x)
p(x) =2x2-4x
p(q(x)) = 2(x-3)2-4(x-3)
= 2(x2-6x+9)-4(x-3)
=2x2-12x+18 -4x+12

Lydia received her salary on Friday. She spent one-half of her salary on rent and then spent $168 on her electric and water bill. Next she spent one-half of what was left on her phone bill. After spending $57.00 on gas for her car, Lydia had $92.00 left. How much did Lydia spend on rent?
A. $298
B. $466
C. $764
D. $932
Answer:
B) $466Step-by-step explanation:
Let the amount of rent is R
Calculate the value of R in reverse order of spending
R = (92 + 57)*2 + 168 = 466Correct choice is B
Answer:
B. $466
Step-by-step explanation:
[tex]\textsf{let}\: x= \textsf{Lydia's salary}[/tex]
[tex]\implies \textsf{rent}=\dfrac{1}{2}x[/tex]
Modelling the given information to find the total salary:
[tex]\implies \left(x-\dfrac{1}{2}x-168\right)-\dfrac{x-\frac{1}{2}x-168}{2}-57=92[/tex]
[tex]\implies \dfrac{1}{2}x-168-\dfrac{\frac{1}{2}x-168}{2}-57=92[/tex]
[tex]\implies \dfrac{1}{2}x-\dfrac{\frac{1}{2}x-168}{2}=317[/tex]
[tex]\implies x-(\frac{1}{2}x-168)=634[/tex]
[tex]\implies x-\frac{1}{2}x+168=634[/tex]
[tex]\implies \dfrac{1}{2}x=466[/tex]
[tex]\implies x=932[/tex]
Therefore, Lydia's total salary was $932
[tex]\implies \textsf{rent}=\dfrac{1}{2}(932)=\$466[/tex]
What is the probability that he will hit fewer than 8 of the bottles?
Using the binomial distribution, it is found that the probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
The probability of a bottle being hit is of p = 0.95.There are n = 10 bottles.The probability that he hits fewer than 8 of the bottles is given by:
[tex]P(X < 8) = 1 - P(X \geq 8)[/tex]
In which:
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 8) = C_{10,8}.(0.95)^{8}.(0.05)^{2} = 0.0746[/tex]
[tex]P(X = 9) = C_{10,9}.(0.95)^{9}.(0.05)^{1} = 0.3151[/tex]
[tex]P(X = 10) = C_{10,10}.(0.95)^{10}.(0.05)^{0} = 0.5987[/tex]
Hence:
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10) = 0.0746 + 0.3151 + 0.5987 = 0.988[/tex]
[tex]P(X < 8) = 1 - P(X \geq 8) = 0.012[/tex]
The probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.

Answer:
(5+8) (5-8)
Step-by-step explanation:
They are both perfect squares.
Answer:
(5+8x)(5-8x)
Step-by-step explanation:
This is a 'difference of two squares" Difference means subtraction and 25 is a perfect square and 64x^2 is a perfect square.
If you know how to factor quadratic trinomials like
ax^2 + bx + c, you can do the same thing here, using:
64x^2 +0x + 25
BUT, there's a shortcut. It is a pattern that you memorize. Since 25 is 5^2, put 5 first in the parenthesis. And since 64x^2 is 8x squared, put 8x second in the parenthesis like this:
(5 8x)
Make two of them:
(5 8x)(5 8x)
Make one a plus and one a minus.
(5 + 8x)(5 - 8x)
Done!
Well, if the directions say "factor" then you are done. If the directions say "solve" then put each piece equal to zero and solve for x.

A rectangle has a perimeter of 36 feet and a base of 14 feet. What is the height?
Answer:
The answer is 4.
Step-by-step explanation:
If this shape has a perimeter of 36, and the base has a length of 14, you subtract 36 - 28 because there are two sides that have a length of 14. You get 8 by subtracting 36 - 28, and divide the answer by 2.

The angle XYZ has and angle y which is twice the size of x. If the third angle is 20 degree what is the value of x and y
The value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.
What is triangle angle sum theorem?According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.
The angle XYZ has an angle y which is twice the size of x. Thus,
2x=y
The third angle is 20 degree, which is Z. Thus,
z=20
By the triangle angle sum theorem,
x+y+x=180
x+2x+20=180
3x=180-20
x=160/3
x=53.33
The measure of angle y is,
y=2×53.33
y=106.66
Thus, the value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.

Triangle E has a perimeter of 125 inches. Two of
its side lengths are 26 inches and 55 inches.
What is its missing side length?
Answer:
44 inches
Step-by-step explanation:
perimeter of triangle = length of side 1 + length of side 2 + length of side 3
length of side 1 = 26
length of side 2 = 55
125 = 26 + 55 + length of side 3 = 81 + length of side 3
subtract 81 from both sides to get the length of side 3
length of side 3 = 44 inches
