Super hero academy's ratio of boys to girls is 5:3. If 7th grade has 150,
7th grade students how many boys and girls are in 7th grade?
Answers
Answer:
94 boys and 56 girls.
Step-by-step explanation:
150/8 = 18.75 = x
b=x*5 = 94
g=x*3 = 56
b+g=150
Looking at the question, we see that the ratio of boys to girls is 5:3, the total is 8. We are trying to find what the ratio of boys to girls is while the total is 150. Now, we can easily divide 150 by 8, finding one part of our answer! 150 ÷ 8 ≈ 18 [tex]\frac{3}{4}[/tex]. now to multiply that by the amount of boys and girls (5:3), 18 [tex]\frac{3}{4}[/tex] × 5 = 93 [tex]\frac{3}{4}[/tex] and 18 [tex]\frac{3}{4}[/tex] × 3 = 56 [tex]\frac{1}{4}[/tex]. After we round we get 94:56.

Which table represents a linear function?
Answers
Answer:
Table 1 (leftmost)
Step-by-step explanation:
A linear function has a common difference between all of the x-values. This means that all the x-values change by the same amount relative to the change in y. In this case, the x-value increases by 1/2 every time that y increases by 1. The other tables do not work because their change is inconsistent. There is no number being added each time. Therefore, they are not linear. If you were to graph these tables, only table 1 would make a straight line.

Answer:
Step-by-step explanation:
While I can not give you the exact answer as it is a graph, it's worth noting that the function is in f(x) = mx + b form.
This means the first point with an x coordinate of 0 will start at 6, and for each increase in one on the x-axis, we add 2.4.
So, the first coordinate is (0,6), the next is (1,8.4), and so on until you reach the end. That shouldn't take very long provided you can compute addition mentally.

The probability that none of the selected adults say that they were too young to get tattoos is 0.3512
What is Binomial probability distribution?The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
14% say that they were too young when they got their tattoos.
So, p= 0.14.
Six adults who regret getting tattoos are randomly selected
So, n=6.
Now, the probability that none of the selected adults say that they were too young to get tattoos.

Decide whether it would be more convenient to solve the system of equations by substitution or elimination.

Answers
The more convenient method to solve the given system of equations is by elimination.
Solving systems of linear equationFrom the question, we are to determine whether it would be more convenient to solve the system of equations by substitution or elimination
The given system of equations is
2 = 4y - 10 ----------- (1)
7x +12y = 7 ----------- (2)
In equation (1), we can see that there is no variable x in the equation. Thus we can solve for y and then substitute the value of y into equation (2).
That is,
From equation (1)
2 = 4y - 10
2 + 10 = 4y
12 = 4y
12/4 = 4y/4
3 = y
∴ y = 3
Now, we can substitute the value of y into equation (2) to determine the value of x
Hence, the more convenient method to solve the given system of equations is by elimination.

A math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Answer is 1/10
Answers
Answer:1/10
Step-by-step explanation:so easy
The probability that the students she selects are both boys is 1/10.
What is a probability? Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates complete certainty.Given is that a math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition.
The probability that the students she selects are both boys -
P{E} = P{1} x P{2}
P{1} : randomly selecting a seventh grader as a boy.
P{2} : randomly selecting a eight grader as a boy.
We can write -
P{1} = n{f}/n{s} = 1/5
P{2} = n{f}/n{s} = 5/10 = 1/2
P{E} = P{1} x P{2}
P{E} = 1/5 x 1/2
P{E} = 1/10
Therefore, the probability that the students she selects are both boys is 1/10.
