Answer:
B. y = 3x - 14
Step-by-step explanation:
Since the line is parallel, your slope will be 3. You're given a point, so you can use point-slope form to find the equation. Point-slope form is:
y - y1 = m(x - x1) where (x1, y1) is the point that they gave you and m is the slope. So:
y - (-2) = 3(x - 4) --> Start to simplify this by changing - (-2) to +2 and distributing the 3 to (x - 4).
y + 2 = 3x - 12 --> Subtract 2 from both sides.
y = 3x - 14
Indicate which formula you would use to solve for the missing side B and then write your answer correct to two decimal places.Write only the formula down.. Single line text.
Answer:
44.04°
Step-by-step explanation:
We would use the Law of Sines, [tex] \frac{sin(A)}{a} = \frac{sin(B)}{b} =\frac{sin(C)}{c} [/tex]
Applying the formula, let's find b°:
Thus:
[tex] \frac{sin(b)}{3.6} = \frac{sin(100)}{5.1} [/tex]
Cross multiply
[tex] sin(b)*5.1 = sin(100)*3.6 [/tex]
Divide both sides by 5.1
[tex] sin(b) = \frac{sin(100)*3.6}{5.1} [/tex]
[tex] sin(b) = 0.69516 [/tex]
[tex] b = sin^{-1}(0.69516) [/tex]
b = 44.0399685° ≈ 44.04° (2 decimal places)
A bag contains 9 orange marbles and 36 green marbles. If a representative sample contains 2
orange marbles, then how many green marbles would you expect it to contain? Explain.
Because the ratio of orange marbles to green marbles is in the population, the expected number
of green marbles is times the number of orange marbles in the representative sample. There
should be green marbles.

The national average for the number of students per teacher for all U.S. public schools is 15.9. A random sample of 12 school districts from a moderately populated area showed that the mean number of students per teacher was 19.2 with a variance of 4.41. Assume a normal distribution is appropriate for the number of students per teacher.a)[7 pts] Estimate the true mean number of students per teacher with 95% confidence from the random sample. b) [6 pts] A researcher makes the claim that moderately populated districts have a different number of students per teacher than the national average. Do the data support this claim
Answer:
The 95% confidence interval of the mean is
(17.8658, 20.5342)
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 15.9
Given that the size of the sample 'n' =12
Mean of the sample x⁻ = 19.2
Given that the variance of the sample = 4.41
The standard deviation of the sample (S) = 2.1
Step(ii):-
Degrees of freedom = n-1
ν = n-1 = 12-1=11
t₀.₀₅ = 2.2010
The 95% confidence interval is determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )[/tex]
[tex](19.2 - 2.2010 \frac{2.1}{\sqrt{12} } , 19.2 + 2.2010 \frac{2.1}{\sqrt{12} } )[/tex]
(19.2 - 1.3342 , 19.2+1.3342)
(17.8658 , 20.5342)
Final answer:-
The 95% confidence interval of mean is
(17.8658 , 20.5342)

find the area of the shaded sector of the circle
Answer:
(175/9)π m²
Step-by-step explanation:
Area of the shaded sector = θ/360 × πr²
Where,
θ = 180° - 110° = 70°
r = ½(20) = 10 m
Substitute
Area = 70/360 × π × 10²
Area = 7/36 × π × 100
Area = (7×100)/36π
Area = (700/36)π = (350/18)π = (175/9)π m²

The inequality is solved and the solution is x > 8/3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
18 - 3x < 10
Adding 3x on both sides , we get
3x + 10 > 18
Subtracting 10 on both sides , we get
3x > 8
Divide by 3 on both sides , we get
x > 8/3
Hence , the inequality is x > 8/3

A sales and marketing management magazine conducted a survey on salespeople cheating on their
expense reports and other unethical conduct. In the survey on 200 managers, 58% of the managers
have caught salespeople cheating on an expense report, 50% have caught salespeople working a
second job on company time, 22% have caught salespeople listing a "strip bar" as a restaurant on an
2 expense report, and 19% have caught salespeople giving a kickback to a customer.
construct a 95% confidence interval estimate of the population
3 proportion of managers who have caught salespeople cheating on an expense report.
Answer:
The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
In the survey on 200 managers, 58% of the managers have caught salespeople cheating on an expense report.
This means that [tex]n = 200, \pi = 0.58[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.58 - 1.96\sqrt{\frac{0.58*0.42}{200}} = 0.5116[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.58 + 1.96\sqrt{\frac{0.58*0.42}{200}} = 0.6484[/tex]
The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).

If F(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f°g)(x)?
Answer:
The composite function is
[tex](f \circ g)(x) = 3x^2 + 5[/tex]
Step-by-step explanation:
Composite functions:
Suppose that we have two functions, f and g. Their composite is given by:
[tex](f \circ g)(x) = f(g(x))[/tex]
In this question:
We have that:
[tex]f(x) = 3x + 2[/tex]
[tex]g(x) = x^2 + 1[/tex]
The composite function is:
[tex](f \circ g)(x) = f(g(x)) = f(x^2+1) = 3(x^2 + 1) + 2 = 3x^2 + 3 + 2 = 3x^2 + 5[/tex]
The composite function is
[tex](f \circ g)(x) = 3x^2 + 5[/tex]

The length of a rectangle is 5 less than twice the width, and the area of the rectangle is 52 ft^2. Find the dimensions of the rectangle.
9514 1404 393
Answer:
6.5 ft wide by 8 ft long
Step-by-step explanation:
We can let x represent the width of the rectangle. Then the length is ...
L = 2x -5
and the area is ...
A = LW = (2x -5)(x) = 52
2x² -5x -52 = 0 . . . . . put in standard form
(2x -13)(x +4) = 0 . . . . factor
x = 6.5, -4 . . . . . . . . . . values that make the factors zero
The length is then ...
L = A/W = 52/6.5 = 8
or
L = 2W -5 = 2(6.5) -5 = 13 -5 = 8
The rectangle is 6.5 feet wide and 8 feet long.

The expression sin(23°)cos(7°) + cos(23º)sin(7°) is equivalent to
Answer:
[tex]\sin(30)[/tex]
Step-by-step explanation:
Given
[tex]\sin(23) \cos(7) + \cos(23) \sin(7)[/tex]
Required
An equivalent expression
The above is an illustration of the sine formula which states:
[tex]\sin(A) \cos(B) + \cos(A) \sin(B) = \sin(A + B)[/tex]
In this case:
[tex]A = 23\\ B = 7[/tex]
So:
[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(23 + 7)[/tex]
[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(30)[/tex]
Hence, an equivalent expression is: [tex]\sin(30)[/tex]

so 8 tons
Step-by-step explanation:
Answer:
8 tons is larger than 14,000 pounds.
Step-by-step explanation:
Here is my explanation:
One ton (same thing as a short ton) is equivalent to 2,000 pounds.
So 8 tons is basically just 2,000 * 8 which is equal to 16,000.

Given:
P = 7500
r = 5.5% or 0.055

Work:
I = Prt
I = 7500(0.055)(2)
I = 412.5(2)
I = 825
what is order of operations and why is it important
Answer:
PEMDAS
Step-by-step explanation:
The order of operations is the order in which you solve an equation to find the correct answer. This is very important because randomly solving parts of an equation without using the order of operations will result in the wrong answer. The order of operations is PEMDAS which stands for: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Example:
[tex](2*2)^{2}+6/3-1[/tex]
Using PEMDAS to solve this equation we get 17 as our answer. However, if we solve it in order of how it appears we end up with 19/3 or 6.33, which is a very different answer.
