8, 32, 64, 512
2, 8, 32, 128,
32, 128, 512, 2048
Answer: B, but technically, all of them are correct except C.
Step-by-step explanation:
First, you fill in 1 for n:
= 2 x 4(1)
= 2 x 4
= 8
Next, I filled in 4 for n:
= 2 x 4(4)
= 2 x 16
= 32
Then, I filled in 8 for n:
= 2 x 4(8)
= 2 x 32
= 64
You can already figure this one out, and the answer is B.
Answer:
all are correct except the third choice.

Mr. Sanders teaches a painting class. He makes the histogram below to summarize the
number of paintings each student has completed since the class began. Mr. Sanders says
that the histogram shows that of the students have finished 12 or more paintings.
Number of Paintings
Finished by Students
Number of Students
N
0-2 3-5 6-8 9-11 12-14 15-17
Number of Finished Paintings
What error did Mr. Sanders likely make, and what is the actual fraction of students who have
completed 12 or more paintings? Use the drop-down menus to explain his reasoning and correct
his mistake.
Mr. Sanders likely found that of the students have completed 12 or more paintings because
there are Choose... bars on the histogram, and choose... of the bars represent
students with 12 or more completed paintings. The actual fraction of the students who have
completed 12 or more paintings is Choose...
Answer:
Answer: (1st box) = 6 (2nd box) = 2 (3rd box) = 2/3
Step-by-step explanation:
I got this question too and I got it right. ❤️
Mr. Sanders most certainly discovered that one-third of pupils have done 12 or more paintings because the histogram has six bars, two of which reflect students who have completed 12 or more paintings. The actual percentage of pupils who have completed 12 or more paintings is [tex]\frac{4}{19}[/tex].
Mr. Sanders' class has 19 students. That histogram has six bars. He most likely assumed it because [tex]\frac{2}{6} = \frac{1}{3}, \frac{1}{3}[/tex] of his pupils finished 12 or more paintings. That is not the case. 2 different isn't even a whole number. The other dates are[tex] \frac{2}{3}, \frac{4}{19}, \ and \ \frac{4}{17}[/tex]. Two-thirds and 4 are not whole figures either. That leaves [tex]\frac{4}{19}[/tex]. Four-nineteenths equal a complete number four. Since there are no such things as partial pupils, we must enter [tex]\frac{4}{19}[/tex].Therefore, the answer is "[tex]\to (1^{st}\ box) = 6 (2^{nd}\ box) = 2 (3^{rd}\ box) = \frac{2}{3}[/tex]"

Solve the following inequality in two ways and make a claim as to which
method is more efficient.
1/4 (8n - 12) < n + 2
Answer:
The solution of the given inequality n < 5
Step-by-step explanation:
Explanation:-
Given inequality
[tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]
Step(i):-
Cross multiplication '4' we get
8 n - 12 < 4 ( n +2)
8 n - 12 < 4 n + 4×2
8 n - 12 < 4 n +8
Subtracting '4 n ' on both sides, we get
8 n - 4 n - 12 < 4 n - 4 n +8
4 n - 12 < 8
Step(ii):-
Adding ' 12 ' on both sides , we get
4 n -12 + 12 < 8 + 12
4 n < 20
Dividing "4' on both sides , we get
n < 5
The solution is n < 5
Conclusion:-
The solution of the given inequality n < 5

Is (3, 2) a solution of -8x – 2y < 6?
Answer:
yes
Step-by-step explanation:
To determine if the point is a solution, substitute the coordinates into the left side of the inequality, evaluate and compare with right side.
- 8(3) - 2(2) = - 24 - 4 = - 28 < 6
Thus (3, 2) is a solution
Answer:
Yes.
Step-by-step explanation:
Let's substitute x = 3 and y = 2 into the inequality:
-8(3) - 2(2) = -28 which is less than 6 so it is a solution.
Find the measure of angle U
Answer:
30 degrees
Step-by-step explanation:
first you have to find angle TSU which is 70 degrees
you get this my doing 180 - 110
then you add up all the angles in the triangle
so, 80 plus 70
you get 150
then you do 180 - 150 and get 30 degrees

7. The distance between point (–4, 5) and another point is 10. What are the possible
coordinates of the other point?
A (2, 2)
B (2, 3)
C (2, –3)
D (–2, –3)
Answer:
D (-2, -3)
Step-by-step explanation: The distance is 10 units, so you take -4 (x) and go over 2 spaces so your at x = -2, and 2 units are down, 8 more to go. Then for (y) you do 5-8 and get -3 so now y = -3 . Now you have moved 10 spaces because 2 + 8 = 10 spaces, and are left at D (-2, -3).

The possible outcomes are 0, 1, 2, …, 95 correct answers.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
P(correct) = 0.2
N=95
Now,
In this case, the random variable is the number of correct answers on a test with 95 five-choice multiple choice questions. Each question has a probability of 0.2 to be guessed correctly and a value of 1 point for each correct answer.
To find the expected value, we need to multiply the probability and the value for each possible outcome and then add them up.
Therefore, by probability the answer will be 0, 1, 2, …, 95 correct answers.

Answer these questions about finding the missing angle measures. What is the measure of ∠Q? What is the measure of ∠T? What can be concluded about these triangles?
Answer:
<Q = 44.4
<T = 44.4
The triangles are similar
Step-by-step explanation:
Both triangle QSR and triangle TUV are similar triangles since the corresponding angles are equal.
Similar figuresTwo figures are similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. Hence all the corresponding angles are similar.
From the diagram:
∠Q + ∠R + ∠S = 180° (angle in a triangle)
∠Q + 98 + 37.6 = 180
∠Q = 44.4°
∠T + ∠U + ∠V = 180° (angle in a triangle)
∠T + 98 + 37.6 = 180
∠T = 44.4°

How do you find the area of a pizza with a diameter is 18 inches
Answer:
The area of the pizza with a diameter of 18 inches is 254.34 inches.
Step-by-step explanation:
The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.
Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.
Then, we need to plug the radius in the formula:
A = 3.14 x 9^2
9 squared or 9 times 9 equals 81
Next, multiply 81 by 3.14 and you get 254.34
Lastly, add the units of measurement, which would be inches.

The area of trapezoid is 120 sq inches. It two parallel sides are 6 inches and 14 inches respectively. What is the height? (with explanation)
Answer:
height = 12 cm
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h(a + b)
where h is the height and a, b the parallel bases.
Here A = 120, a = 6 and b = 14 , thus
[tex]\frac{1}{2}[/tex] h (6 + 14) = 120
[tex]\frac{1}{2}[/tex] h × 20 = 120
10h = 120 ( divide both sides by 10 )
h = 12 cm
A jeweler sells gems at a cost in dollars per centigram that is 4 more than 6 times the weight of the gem in centigrams.
Thus, a gem that weighs w centigrams will be sold at a price of 6w + 4 dollars per centigram - meaning that a larger,
heavier gem will cost more per centigram than a smaller gem. If the jeweler sold a single gem for about $2500, what
did the gem weigh to the nearest centigram?
Answer:
416 centigrams

2500 = 6w + 4
