Classify the polynomial by the number of terms.
mx+b
•Trinomial
•Monomial
•Polynomial
•Binomial
Classification:
Monomial: One term
Mono = One
Polynomial: Multiple terms e.g. (2,3,4 and so on)
Poly: Many
Binomial: Two terms
Bi = Two
Trinomial: Three terms
Tri = Three
The expression of "mx + b" would be classified as a monomial due to it having only one exponent.
1. The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 800 voters in the town and found that 71% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is more than 68 %. Testing at the 0.02 level, is there enough evidence to support the strategist's claim? State the null and alternative hypotheses.

Testing at the 0.02 level, is there enough evidence to support the strategist's claim? State the conclusion of the hypothesis test.
Answer:
See step by step explanation
Step-by-step explanation:
Sample size n = 800
p₁ = 71 % p₁ = 0,71 and q₁ = 0,29
Claim from political strategy wants evaluation to see if that sample implies that residents who favor the construction are more than 68 %
Then
p₀ = 68% p₀ = 0,68
Sample size 800 big enough to use the approximation of binomial distribution to normal distribution
1) Hypothesis Test
Null Hypothesis H₀ p₁ = p₀
Alternative Hypothesis Hₐ p₁ > p₀
2)Test Statistics z (s)
z(s) = ( p₁ - p₀ ) / √p₁*q₁/n
z(s) = 0,03 / √0,71*0,29/800
z(s) = 0,03 / 0,016
z(s) = 1,875
3) In the problem statement the expression " more than " has to be formulated in the alternative hypothesis and indicates that the test is one tail test to the right
4) z(s) = 1.875 from z-Table we get p-value = 0,030
Now significance level is α = 0,02
Therefore p-value > 0.02
Then that value corresponds to the acceptance region for H₀.
We don´t have enough evidence to support the strategist´s claim
5) The level of significance is α = 0,02
6) If now we change α to be equal to 0,01 α = 0,01
p-value > 0,01 and still we have to accept H₀
7) We accept H₀ we are not able to support strategist´s claim
Which ordered pair is the solution to the system of equations below when
using the matrix tool?
9x - 3y = 54
9x +1 ly = 12
Answer:
(7, -3)
Step-by-step explanation:
9x - 3y = 54
9x +1 ly = 12
Subtract both expresion
-3y - 11y = 54 - 12
-14y = 42
y = 42/-14
y = -3
Substitute y = -3 into 1;
From 1, 9x - 3y = 54
9x - 3(-3) = 54
9x - 9 = 54
9x = 54 + 9
9x = 63
x = 63/9
x = 7
Hence the solution to the system of equation is (7, -3)

In problem formulation, the a. constraints are expressed in terms of the obtained objective function coefficients. b. objective is expressed in terms of the decision variables. c. nonnegativity constraints are always ignored. d. optimal solution is decided upon.
Answer: B. objective is expressed in terms of the decision variables
Step-by-step explanation:
Linear programming refers to an optimization technique that is used for a linear constraints system and the objective function.
The objective function simply means the quantity that an individual wants to optimize. It should be noted that the aim of linear programming is to get the values of the variables which will minimize or maximize the objective function. In problem formulation, objective is expressed in terms of the decision variables.
Therefore, the correct option is B

The Coopers own two vehicles, a mini-van and sedan. The following functions represent the resale value of both cars, in thousands of dollars,
after x years.
Mini-Van: f(1) = 32(0.8)*
Sedan: g(t) = 25(0.8)
Write function t that represents the total resale value, in thousands of dollars, of the two vehicles.
Answer:
[tex]h(x) = 57(0.8)^x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 32(0.8)^x[/tex]
[tex]g(x) = 25(0.8)^x[/tex]
Required
A function that represents the total resale value of the two vehicles
To do this, we simply add up the functions
[tex]h(x) = f(x) + g(x)[/tex]
[tex]h(x) = 32(0.8)^x + 25(0.8)^x[/tex]
Factorize
[tex]h(x) = (32 + 25)(0.8)^x[/tex]
[tex]h(x) = 57(0.8)^x[/tex]
The range of the function defined as y = 5x is
The required range of the function y = 5ˣ is y > 0. Option b is correct.
Given that,
To determine the range of the function y = 5ˣ.
The function which is in format f(x) =a^x where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
What is the range?Range, it is the set of the values that come out to an outcome for certain mathematical operations.
Here,
unction y = 5ˣ,
Since the independent variable is at the exponent so the range of the function is always greater than 1.
Thus, the required range of the function y = 5ˣ is y > 0. Option b is correct.

Answer:
The first one is exponential, the second one is linear, and the last one is quadratic.
Step-by-step explanation:
The first one is exponential, because the values are increasing at an increasing rate. In other words, the difference between any consecutive x-values yield a bigger difference.
The second one is linear, because the values are increasing at a constant rate.
The last one is quadratic, because the values decrease, and then increase, which can be represented by a parabola for a quadratic equation.

if the variance of the data values in a sample is 361, what is the standard deviation of the data values
If the variance of the data values in a sample is 361, Then the standard deviation will be 19.
What is the standard deviation?
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Here the relationship between the standard deviation and the variance is given as:-
[tex]\sigma[/tex]² = Variance
[tex]\sigma[/tex] = √ Variance
[tex]\sigma[/tex] = √361 = 19
Hence the variance of the data values in a sample is 361, Then the standard deviation will be 19.

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the required graph is not attached. The general explanation is as follows:
To calculate the slope of a line, we select two points on the line.
Assume, the points are:
[tex](x_1,y_1) = (-1,0)[/tex]
[tex](x_2,y_2) = (0,-4)[/tex]
The slope will be:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4-0}{0--1}[/tex]
[tex]m = \frac{-4}{1}[/tex]
[tex]m = -4[/tex]
For each of the options, the slope is calculated from the following representation
[tex]y = mx + b[/tex]
Where
[tex]m \to[/tex] slope i.e. the coefficient of c
By comparison, we have:
[tex]A.\ m =4[/tex]
[tex]B.\ m = 7[/tex]
[tex]C.\ m = -4[/tex]
[tex]D.\ m = -4[/tex]
So: (C) and (D) have the same coefficients as the assumed function
