Let's analyze which of the scenarios given, represent a 85% of success on a test, this way:
Scenario A:
56 out of 70 points = 56/70 = 0.8
This scenario represents a 80% of success
Scenario B:
78 out of 90 points = 78/90 = 0.867
This scenario represents a 86.7% of success
Scenario C:
102 out of 120 points = 102/120 = 0.85
This scenario represents a 85% of success

Identical twins happen once
in 250 births. How many pairs
of these twins might be at a
school with 2,750 students?
Answer:
11
Step-by-step explanation:
if there are twins born every 250 births take your large number (2,750) and divide it by 250 to get your answer
There are 11 pairs of twins at a school with 2750 students.
What is division?Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.
Given identical twins happen once in 250 births,
total number of students in school = 2,750
to find the pair of twins divide the total number of students by 250
= 2750/250 = 11
Hence there are 11 pairs of twins in 2,750 students.

For questions 6-8, evaluate the
expression and give the exact value, if
possible. Otherwise, approximate to the
nearest tenth.
64
31
16
(6) The value of [tex]\sqrt{64}[/tex] is 8.
(7) The value of [tex]-\sqrt{31}[/tex] is -5.6
(8) The value of [tex]-\sqrt{16}[/tex] is -4
Explanation:
(6) The expression is [tex]\sqrt{64}[/tex]
Since, 64 is a perfect square, this can be written as [tex]8 \times 8[/tex].
Thus, the expression can be written as
[tex]\sqrt{64}=\sqrt{8 \times 8}=\sqrt{8^{2} }[/tex]
The square root gets cancelled. Thus, we have,
[tex]\sqrt{64}=8[/tex]
Thus, the value of [tex]\sqrt{64}[/tex] is 8.
(7) The expression is [tex]-\sqrt{31}[/tex]
Since, 31 is not a perfect square and solving the expression using a calculator, we get,
[tex]-\sqrt{31}=-5.56776[/tex]
Rounding off to the nearest tenth, we get,
[tex]-\sqrt{31}=-5.6[/tex]
Thus, the value of [tex]-\sqrt{31}[/tex] is -5.6
(8) The expression is [tex]-\sqrt{16}[/tex]
Since, 16 is a perfect square, this can be written as [tex]4\times 4[/tex]
Thus, the expression can be written as
[tex]-\sqrt{16}=-\sqrt{4\times 4}=-\sqrt{4^{2} }[/tex]
The square root gets cancelled. Thus, we have,
[tex]-\sqrt{16}=-4[/tex]
Thus, the value of [tex]-\sqrt{16}[/tex] is -4.

Justin has $7.50 more than Eva ,and Emma has 12$ less than Justin. Together, they have a total of $63.00 How much money does each person have?
Eva has $20.00, Justin has $27.50 and Emma has $15.50
Step-by-step explanation:
The given is:
Justin has $7.50 more than EvaEmma has 12$ less than JustinTogether, they have a total of $63.00We need to find how much money each person has
Assume that Eva has $x
∵ Eva has $x
∵ Justin has $7.50 more than Eva
- Add 7.50 to x
∴ Justin has = x + 7.50
∵ Emma has $12 less than Justin
- Subtract 12 from (x + 7.50)
∴ Emma has = x + 7.50 - 12 = x - 4.50
∵ Together, they have a total of $63.00
- Add x , (x + 7.50) and (x -4.50), then equate the sum by 63.00
∴ x + (x + 7.50) + (x - 4.5) = 63.00
- Add like terms
∴ (x + x + x) + (7.5 - 4.5) = 63.00
∴ 3x + 3 = 63.00
- Subtract 3 from both sides
∴ 3x = 60.00
- Divide both sides by 3
∴ x = 20.00
Substitute x by 20.00 in each expression above
∴ Eva has = $20.00
∴ Justin has = 20.00 + 7.50 = $27.50
∴ Emma has = 20.00 - 4.50 = $15.50
Eva has $20.00, Justin has $27.50 and Emma has $15.50

Omar buys candy that costs $8 per pound. He will spend at least $40 on candy. What are the possible numbers of pounds he will buy?
Use p for the number of pounds Omar will buy.
Write your answer as an inequality solved for p.
HELP ASAP
Omar will buy at least 5 pounds of candy. To find this, divide his minimum spending ($40) by the cost per pound of candy ($8). The inequality solved for p is p \geq 5, meaning Omar can buy 5 or more pounds of candy.
Explanation:To find out the possible number of pounds of candy Omar will buy, we can set up an inequality using the given information. We know the cost per pound of candy is $8, and Omar is going to spend at least $40 on candy. Therefore, the inequality representing the situation can be written as:
8 imes p \\(cost per pound \\ times number of pounds)\\ \geq 40 (Omar's minimum spending)
To solve for p, the number of pounds, we divide both sides of the inequality by 8:
p \geq \frac{40}{8} \Rightarrow p \geq 5
So, Omar will buy at least 5 pounds of candy. This means that the possible numbers of pounds he may buy are 5 or more.

dentify the Pythagorean triple. A) 3, 6, 12 B) 8, 16, 32 C) 12, 34, 30 D) 28, 45, 53
Answer:
Therefore (28,45,53) is a Pythagorean triple.
Step-by-step explanation:
A Pythagorean triple consists of three positive integers a,b and c such that
a²+b²=c²
1.
3²+6²=45 and 12²=144
∴3²+6²≠144
Therefore (3,6,12) is not a Pythagorean triple.
2.
8²+16²= 330 and 32²= 1024
∴8²+16²≠32²
Therefore (8,16,32) is not a Pythagorean triple.
3.
12²+34²=1024 and 34²=5611
∴12²+34²≠34²
Therefore (12,34,30) is not a Pythagorean triple.
4.
28²+45²=2809 and 53²=2809
∴28²+45²=53²
Therefore (28,45,53) is a Pythagorean triple.

what is the sum of 2/10 + 6/100
Answer:
26/100 which is simplified to 13/50
Step-by-step explanation:
you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50
The sum of 2/10 and 6/100 is 13/50.
To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.
The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.
Now, we'll rewrite both fractions with the common denominator of 100:
2/10 = (2/10) * (10/10) = 20/100
6/100 = 6/100
Now that both fractions have the same denominator, we can add them together:
20/100 + 6/100 = (20 + 6)/100 = 26/100
Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
(26 ÷ 2) / (100 ÷ 2) = 13/50

Hours Spent at Water Park A 2-column table with 4 rows titled Hours Spent at Water Park. Column 1 is labeled Hours with entries 4, 5, 6, 7. Column 2 is labeled Tally with entries 4, 5, 3, 4. Write a statistical question that might have been asked to gather the data. Then explain why it is statistical.
Answer:
The question is: How much time do people spend in the water park?It is a statistical because the answer comes from a sample instead of from the entire population.
Explanation:
Rewrite the table
Hours Spent at Water Park
Hours Tally
4 4
5 5
6 3
7 4
These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.
The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.
And the question most likely was made at the exit of a water park, when the people were leaving the park.
Thus, the statistical question could be How much time do people spend in the water park?
It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.
The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.
Answer:
sample responce
Step-by-step explanation:
“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.
