Correct The remainder when you divide is
The remainder theorem indicates that remainder when the polynomial x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by (x - 1) is 8
What is the remainder theorem?The remainder theorem specifies the relationship between the division of a polynomial by a linear factor to the value of the polynomial at a specified point
The remainder when the polynomial expression; x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by x - 1, can be found using the remainder theorem by plugging in x = 1 in the function as follows;
f(1) = 1⁵ - 3 × 1⁴ - 2 × 1³ - 5 × 1² + 5 × 1 + 12 = 8
The remainder when x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by (x - 1) therefore is 8

The sum of three consecutive integers is 180. What is the largest integer?
Answer:
61
Step-by-step explanation:
Here's a neat trick when you have an odd number of consecutive numbers.
Call the middle number k
Then the smaller number is k-1
The larger number is k + 1
The two ones will cancel.
k-1 + k + k-1 = 180
3k = 180
k = 180/3
k = 60
Therefore the largest number is k + 1 = 60 + 1 =61

The goal is to get x all by itself on one side of the equal sign.Is x by itself? No, it's cubed, or multiplied times itself three times.
So we need to use the opposite operation.
The opposite of cubing is taking the cube root, so we take the cube root of both sides:
\(\star~\large\pmb{\sqrt[3]{x^3}=\sqrt[3]{216}}\)
On the left, the cube root sign and the cube cancel, because they're opposite, and we're left with x.
On the right, we take the cube root of 216, which gives us:

If 2.29 x 19.79 = 45.3191, then without actual multiplication the value of 0.0229 x 1979 is?
Answer:
The answer remains the same (45.3191)
Step-by-step explanation:
0.029 is 100 times smaller than 2.29 but 1979 is 100 times bigger than 19.79. The 100’s cancel each other out so the answer remains the same.
Line A B has a negative slope and goes through points (negative m, p) and (w, z). Line A prime B prime has a positive slope and intersects with line A B. Which coordinate for points A' and B' would help prove that lines AB and A'B' are perpendicular? A': (p, m) and B': (z, w) A': (p, m) and B': (z, −w) A': (p, −m) and B': (z, w) A': (p, −m) and B': (z, −w)
Answer:
(B)A': (p, m) and B': (z, −w)
Step-by-step explanation:
Line AB has a negative slope and goes through points (-m, p) and (w, z).
Line A'B' has a positive slope and intersects with line AB.
Definition: Two lines are perpendicular if the product of their slopes is -1.
Slope of AB
\(m_1=\dfrac{z-p}{w-(-m)} \\m_1=\dfrac{z-p}{w+m}\)
From the options, we consider the coordinates whole slope multiplied by the slope of AB gives a result of -1.
In Option B: A': (p, m) and B': (z, −w)
Slope of A'B'
\(m_2=\dfrac{-w-m}{z-p} \\m_2=\dfrac{-(w+m)}{z-p}\)
The product of the slopes
\(m_1m_2=\dfrac{z-p}{w+m}\times \dfrac{-(w+m)}{z-p} =-1\)
Therefore, the coordinate for points A' and B' which would help prove that lines AB and A'B' are perpendicular is A': (p, m) and B': (z, −w).
You can try to calculate the slope of the others. They would not satisfy this condition.

NOTE: Angles not necessarily drawn to scale.
Answer:
x = 45°
Step-by-step explanation:
Vertical Angle Theorem
When two straight lines intersect, they form two pairs of angles. The vertically opposite (non-adjacent) angles are congruent (equal).
From inspection of the given diagram, the straight line with points C and D and the straight line with points F and G intersect at point E.
Therefore, angles ∠FEC and ∠DEG are vertically opposite, and so they are equal.
From inspection of the diagram:
∠FEC = x°∠DEG = 20° + 25° = 45°Therefore:
⇒ ∠FEC =∠DEG
⇒ x = 45°
A researcher plans to study the causal effect of police on crime, using data from a random sample of U.S. counties. He plans to regress the county’s crime rate on the (per capita) size of the county’s police force. (a) Explain why this regression is likely to suffer from omitted variable bias. Which variables would you add to the regression to control for important omitted variables
Answer and Step-by-step explanation:
This regression can generate an omitted variable bias, because the researcher did not determine any parameters or real data to measure it. In this case, the researcher determined the crime rate as a dependent variable, but did not establish the facts that influence it and that promote an observable result. In this way, he omitted the independent variable and his research will be inaccurate and incorrect. To control this bias, it is necessary for the researcher to provide a dependent variable such as the level of education in the region, the income distribution in the region, the unemployment rate, the fraction of young men, among others.

Suppose that newborn harbor seal pups have a weight that is normally distributed, with a mean of 22.0 lbs and standard deviation of 1.1 lbs. Find the probability that a newborn pup has a weight above 24.0 lbs.
Answer:
0.0344 = 3.44% probability that a newborn pup has a weight above 24.0 lbs.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 22.0 lbs and standard deviation of 1.1 lbs.
This means that \(\mu = 22, \sigma = 1.1\)
Find the probability that a newborn pup has a weight above 24.0 lbs.
This is 1 subtracted by the p-value of Z when X = 24. So
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{24 - 22}{1.1}\)
\(Z = 1.82\)
\(Z = 1.82\) has a p-value of 0.9656.
1 - 0.9656 = 0.0344
0.0344 = 3.44% probability that a newborn pup has a weight above 24.0 lbs.

Laura owns and operates Aunt Linda’s Pecan Pies. She has learned that her profits, P(x), from the sale of x cases of pies, are given by P(x) = 150x – x2.
a. The company will “break-even” when the profit is zero. How many cases of pies should Laura sell in order to break-even? (Solve for x when P(x) = 0.) Write your answer in a complete sentence with proper grammar and correct spelling.
b. How many cases of pies should she sell in order to maximize profit? What is the maximum profit? Write your answer in a complete sentence with proper grammar and correct spelling.
Step-by-step explanation:
Part a
P(x) = 0
150x - x^2 = 0
x(150-x)
x=0,150
Laura should sell 150 pies in order to "break-even" on her sales.
Part b
Because the maximum profit occurs at the vertex of the function,
x = -b/2a = -150/-2 = 75
P(75) = 150 * 75 - 75^2 = 5625
Laura maximizes her profit to $5625 when she sells exactly 75 pies.

Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
