Answer:
x≥8
Step-by-step explanation:
Answer:
x ≥ 8

Peter was in a line. There were twice as many students in front of him as behind him. Students (more than 3 but fewer than 9) left the line but Peter did not. Then twice as many students were behind Peter as in front. How many students left the line?
Answer:
6 people left
Step-by-step explanation:
4 behind him 8 infront 6 left from infront leaving 4 behind 2 infront
Answer:
6 studentsExplanation:
x = the number of students in front of peter
y = the number of students behind peter
z = the number of students who left, for 3 < z < 9 ∴ z ∈ {4, 8}
system of equations:
x = 2y2(x-z) = y (assuming that the students who left were all among the students who are in front of peter)x = 2y ⇒ y = x/2 (defining y with x)
2(x-z) = y (lets substitute y)
2(x-z) = x/2
2x-2z = x/2
2(2x-2z) = x
4x-4z = x
4x-x = 4z
3x = 4z
if z = 6 (i pluged the numbers from 4 to 8)
then
3x = 4×6
3x = 24
x = 24/3
x = 8
∴ y = 4
8 students were in front of peter and 4 were behind him
6 left
now 2 students are in front of peter and 4 are behind him
8 is twice 4
8-6 = 2
4 is twice 2
Calculate sales tax using the following information:
Taxable amount of the sale: $150
Sales tax percentage: 7%
What is the amount of the sales tax?
Round the answer to the nearest cent (hundredths).
A percentage is a way to describe a part of a whole. The amount of the sales tax is $10.5.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given the taxable amount of the sale is $150, while the Sales tax percentage is 7%. Therefore, the amount of sales tax is,
Amount of sales tax = 7% of $150 = 0.07 × 150 = $10.5
Hence, the amount of the sales tax is $10.5.

You calculate the probability of an event and it turns out to be 0.7, you know
that [2]
A. the event is certainly going to happen.
B. the event is probably not going to happen.
C. the probability of it not happening is 0.3.
D. you made a mistake.
Answer:
C. the probability of it not happening is 0.3.
Step-by-step explanation:
Probability of event happening is of 0.7.
Either it happens, or it does not. The sum of these probabilities is 100%.
0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.
A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.

First find the area of one side.
The area of the side of a cube is s^2 where s is the length if one edge.
The edge length is given as 2/3, so the area of a side is 2/3^2 which is equal to 2/3 x 2/3 = 4/9 square units.
A cube has 6 sides so now to find the surface area of the cube multiply the area of one side by 6 sides:
4/9 square units x 6 = (4 x6)/9 = 24/9 which can be rewritten as 2 2/3 square units
The answer is 2 2/3 units^2
In an early home game, an NBA team made 70.21 percent of their 94 free throw attempts. In one of their last home games, the team had a free throw percentage equal to 76.4 percent out of 89 attempts. Did the team significantly improve its free throw percentage
Answer:
The team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.
Step-by-step explanation:
Given that in an early home game, an NBA team made 70.21 percent of their 94 free throw attempts, and in one of their last home games, the team had a free throw percentage equal to 76.4 percent out of 89 attempts, to determine if the team significantly improved its free throw percentage, the following calculation must be performed:
100 = 94
70.21 = X
70.21 x 94/100 = X
66 = X
100 = 89
76.4 = X
76.4 x 89/100 = X
68 = X
100 = 94
76.4 = X
76.4 x 94/100 = X
72 = X
Therefore, at first glance, the team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.
