Answer:
x: y :

Step-by-step explanation:
y = 10x + 1
(Table)
x: y:
-5 |
-1 |
0 |
1 |
Lets begin plugging in our (x) into the function(x = -5)y = -10(-5) + 1
y = 50 + 1 (if you multiply a negative by a negative it will be positive)
y = 51
(x = -1)y = -10(-1) + 1
y = 10 + 1
y = 11
(x = 0)y = -10(0) + 1
y = 0 + 1
y = 1
(x = 1)y = -10(1) + 1
y = 10 + 1
y = 11
Plug into the table

As the sample size increases, the margin of error _____.
The margin of error is inversely proportional to the sample size. As the sample size increases, the margin of error decreases.
What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
The margin of error is given as
[tex]\rm ME = z\times \sqrt{\dfrac{p(1-p)}{n}}[/tex]
We know that margin of error is inversely proportional to the sample size.
As the sample size increases, the margin of error decreases.

Answer:
A
Step-by-step explanation:
Cylinder volume= V = π r ^2 h
So you times Pie by the radius (diametre divided by two- 3.5) you then square this. After that, times it by the height (10)
So the volume is 384.85.
You then find 30% of this, so times 384.85 by 30%.
You then get an answer of 115.455, and this is equal to A.

#24. you and your friends go to the county fair the cost to get in is $8 and the tickets per game to my cost $0.25 each. Write an equation to create a table of reasonable values and identify the domain and range for the scenario.
The equation of the scenario is y = 8 + 0.25x and the domain is x ≥ 0 and the range is y ≥ 8
How to determine the equation?The given parameters are:
Entrance fee = $8Rate = $0.25 per personLet the total cost be y, and the number of people be x.
The equation would be:
y = Entrance + Rate * x
This gives
y = 8 + 0.25x
Hence, the equation of the scenario is y = 8 + 0.25x
The table of valuesSet x = 0 to 5, and calculate the function values
y = 8 + 0.25 * 0 = 8
y = 8 + 0.25 * 1 = 8.25
y = 8 + 0.25 * 2 = 8.50
y = 8 + 0.25 * 3 = 8.75
y = 8 + 0.25 * 4 = 9.00
y = 8 + 0.25 * 5 = 9.25
So, the table of values is:
x y
0 8
1 8.25
2 8.50
3 8.75
4 9.00
5 9.25
The domain and the rangeThe domain is the set of people that can get in (i.e. at least 0), while the range is the total amount (i.e. at least the entrance fee)
Hence, the domain is x ≥ 0 and the range is y ≥ 8

Martin wants to use coordinate geometry to prove that the opposite sides of
a rectangle are congruent. He places parallelogram ABCD in the coordinate
plane so that A is (0, 0), B is (a,0), C is (a, b), and D is (0, b).
What formula can he use to determine the distance from point D to point A?
A. 0-0)2+(b-0)² = √√b² = b
B. (a-a)2+(b-0)² = 6²
C. (0-0)² + (b-0)² = 6²
OD. √(-a)2+(b-0)²-√√b² = b
The correct answer is option A which is the distance between A and D will be AD = [tex]\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b[/tex].
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
The formula utilised to find the distance between two points is;-
X = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.
AD = [tex]\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b[/tex].

Answer:
Part A:
In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.
Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom
Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.

Researchers believe the true mean is less than 14 days and they plan a hypothesis test at the 5% significance level on a random sample of 60 of these mosquitos. If the alternative hypothesis is correct, for which of the following values of μ is the power of the test greatest?
μ = 9
μ = 7
μ = 10
μ = 14
μ = 18
Based on the alternative hypothesis, the value of μ that will have the greatest test power is μ = 7.
Which value of μ will have the greatest power of test?The alternative hypothesis is that Hₐ : μ < 14.
For the alternative hypothesis to be right, μ will have to be less than 1.4.

For some △MNP: P = 38°, N = 90°, and m = 12 cm. Solve the triangle. Hint: Sketch the
triangle and label all unknown parameters.
Angle M = 52°, n = 15.2cm, p = 9.4cm
What is a triangle?A triangle is a plane shape with three sides and three angles.
To define the triangle completely we have to know the measure of the three angles and three sides.
Analysis:
The triangle is a right-angled triangle
we need to find the remaining angle M and two sides n and p
M + N + P = 180
M + 90 + 38 = 180
M = 180 - 128 = 52°
sin 52 = m/n
m = n sin 52
n = m/sin 52 where m = 12cm
n = 12/0.788 = 15.2cm
sin 38 = p/n
p = n sin 38
p = 15.2 x 0.615 = 9.4cm
In conclusion, solving the triangle means finding M, n and p which are 52°, 15.2cm and 9.4cm respectively.
