Answer:
the 3rd number line
Step-by-step explanation:
first of all, we know That the line starts from zero.
the inequation is n>0
the circle inside should be the hallow one because it's "greater" not greater than or equal to.
n>0 means that n is greater than 0.
in the number line, ( the 3rd one) n is going away from 0. it's going greater than 0.
that is why this is the correct answer.
I hope this clarified any confusion.

Rick bought a fan for his living room he was looking at it while he was installing it wondered to himself what the angle between each blade measured. The fan has 3 blades evenly spaced. What is the angle between each blade and what type of angle are they?
Answers
Answer:
The angle between the two blades is 120 degree.
Step-by-step explanation:
number of blades = 3
The blades are equally spaced.
The total angle around a circle is 360 degree.
So, the angle between the two blades is given by
[tex]\theta =\frac{360}{n}\\\theta =\frac{360}{3} = 120^{o}[/tex]

I am making two kinds of cookies: chocolate chip and lemon cookies Chocolate Chip Cookies It takes 0.250.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.505.50 cups of sugar. How many batches of cookies can I make?
Answers
Answer: 22 batches of chocolate chip cookies
Step-by-step explanation:
A batch of cookies can take 0.25 cups of sugar to make.
You instead have 5.50 cups of sugar.
The number of batches that can be made is:
= Total amount of sugar available / Amount of sugar required for one batch
= 5.50 / 0.25
= 22 batches of chocolate chip cookies

Answers
Answer:
[tex]y=\frac{4}{3}x -8[/tex]
Step-by-step explanation:
So first find the slope of the given line
-2 - 4 = -6
4 + 4 = 8
-6 ÷ 8 = [tex]-\frac{3}{4}[/tex]
The slope of a line perpendicular to another line is the opposite reciprocal of the given slope.
The opposite reciprocal of [tex]-\frac{3}{4}[/tex] is [tex]\frac{4}{3}[/tex]
So now all we need to finish the slope intercept form y = mx + b is b, which is the y intercept.
[tex]y=\frac{4}{3}x+b[/tex]
Now that they give us the X intercept, you can plug in the values (6, 0).
[tex]0=8+b[/tex]
b = -8

What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
The diameter is the longest line that can be drawn inside a circle.
In our daily life, we always see circle objects for example our bike wheel.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
In the given question by the circle theorem that if a curve makes a 2x angle then the extreme point will make the angle on circle as x.
So angle y = half of angle 108°
∠Y = 108°/2 = 54°

A store manager claims that 60% of shoppers who enter her store make a purchase. To investigate this claim, she selects a random sample of 40 customers and finds that 40% of them make a purchase. She wants to know if the data provide convincing evidence that the true proportion of all customers who enter her store that will make a purchase differs from 60%. The P-value of this test is 0.0098. Interpret the P-value.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.

I do believe that it is Option B
(Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.)
Step-by-step explanation:
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
What is p-value?In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.
here, we have,
Given data in the question:
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)}
The number of times p"<0.64 in 150 simulations is 5
Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,

Is a triangle with sides measuring 9 feet, 12 feet, and 18 feet a right triangle?
If you give a link, fake answer, or using for points will be reported.
Answers
Answer:
No, because the Pythagorean theorem does not prove it to be a right triangle
Step-by-step explanation:
is 9² + 12² = 18²?
81 + 144 ≠ 324
Explanation:
Using the Converse of the Pythagorean Theorem which is in square length of the longest side is equal to sum of the square lengths of the other to sides, then the triangle is a right triangle.
So, you make an equation were the longest side (18 in this problem) equals the other two sides (9 and 12).
So the equation would look like:
18^2=9^2+12^2
Then you would solve for each number squared and end up with:
324=81+144
Solve:
324=225
Since the equation is false this is not a right triangle, but according to the obtuse triangle inequality theorem which is if the square length of the longest side is greater than the square length of the other side sides then the triangle is an obtuse triangle. So, this triangle is not a right triangle but an obtuse triangle.

In months the total cost of both options will be the same. That cost will be $.
Answers
Answer:
8 months and $320
Step-by-step explanation:
To find when 30m + 80 = 40m, isolate m.
30m + 80 = 40m
Subtract 40m from both sides.
-10m + 80 = 0
Subtract 80 from both sides.
-10m = -80
Divide both sides by -10
m = 8
To find the cost, substitute 8 as m in one of the equations.
40(8) = 320
