At a basketball game, for every basket team A scored, team B scored 4 baskets. The ratio of the number of baskets scored by team A to the number of baskets for team B is A. 1 to 3
B. 2 to 3
C. 1 to 4
D. 4 to 1
Answers
Answer:
C. 1 to 4
Step-by-step explanation:
The ratio is used to describe situations like "for how many x's, there are many y's". In this case, we are trying to find the ratio for A baskets scored to B baskets scored, team A scores one basket, then team B will score 4 baskets. Then we can write the ratio of A to B as 1:4, which is 1 to 4.

what is _ percent of 100 is 14
Answers
Answer:
It should be 14 percent.
Step-by-step explanation:
14 percent is just 14/100, which if you multiply by 100 gives you 14.
14%
Step-by-step explanation:
Whenever you have anything over 100 (e.g 40/100) that number is always gonna be 40. Like multiplying by 1. 9*1 is 1. Assume the 9 is 90 and assume the 1 is 100. It's always gonna be the numerator instead of the denominator.

How do I find the equation of the line?
Answers
Answer:
1.Identify the slope.
2.Identify the point.
4.Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) .
5.Write the equation in slope-intercept form.
Step-by-step explanation:
Answer:
y=-\frac{2}{3}x+3
Step-by-step explanation:
[tex]y=mx+b[/tex]
There are 4 variables in this equation, and 3 of them are already given. We already have the slope and the (x, y) of a known point. Plug those 3 into the equation and solve for b:
[tex]7=-\frac{2}{3}(-6)+b\\7=4+b\\b=3[/tex]
Now, with the slope and the y-intercept, you can write the equation of the line:

Joan purchased a refrigerator for $1,200. She made a down payment of $65 and paid
$121 a month for 11 months. Find the total installment price of the refrigerator.
Answers
The total installment price is $1331.
What is an installment?Installment means adding the total principal of the loan and the total interest on the principal together and then dividing the sum by the number of installment payments.
For the given situation,
The purchase price of the refrigerator = $1200
Down payment = $65
Monthly installment = $121
Installment period = 11 months
Total installment price = [tex](121)(11)[/tex]
⇒ [tex]\$1331[/tex]
Hence we can conclude that the total installment price is $1331.

Answers
Answer:
87
Step-by-step explanation:
66 + 72 + 87 = 225
225/3 = 87
Answer:
87
Step-by-step explanation:
For problems involving averages, it often works well to consider the differences from the average. Here, Ali desires an average of 75. The total of differences from average will be zero. The differences for the known scores are ...
66 -75 = -9
72 -75 = -3
The total of these is -12, so the third score must have a difference of +12 for the average to be 75
x -75 = 12
x = 87
For the average to be at least 75, the third score must be at least 87.
_____
You can also work this in a more conventional way. The average of the three scores must be at least 75.
(66 +72 +x)/3 ≥ 75
138 +x ≥ 225 . . . . . . multiply by 3, simplify
x ≥ 87 . . . . . . . . . . subtract 138
The lowest mark Ali must receive is 87.

you can’t DIVIDE fractions, so you have to use the “keep-change-flip“ method

What is the independent and dependent variable?In mathematics, independent and dependent variables are values that vary in relation to one another. The dependent variable is dependent on the independent variable, which means that if the value of the independent variable changes, so will the dependent variable.
In this situation, the explanatory variable is the number of text messages sent, because it is believed to influence or "explain" the variation in the response variable, which is the percentage of phone memory used.
The explanatory variable is also sometimes called the independent variable, because it is the variable that is being manipulated or controlled in an experiment. The response variable is also sometimes called the dependent variable, because it is the variable that is believed to depend on the explanatory variable.
Therefore, in this problem, the explanatory variable is the number of text messages sent, and the response variable is the percentage of phone memory used.

Answer:

Step-by-step explanation:
The circumcenter is the center of the circumcircle of the triangle. Each vertex of the triangle lies on that circle. The sides of the triangle are chords of the circle.
The perpendicular bisector of a chord is a line that intersects the center of the circle containing the chord. Hence, the perpendicular bisectors of the sides of a triangle will intersect the circumcenter.

3. You miss a free throw 3/10 of the time
A) likely
B) unlikely
C) certain
D) equally likely
Answers
Converting to a percentage: 3/10 = .3 x 100 = 30%.
Therefore, 3/10=30%. So, you only miss 30% of the time, which means that you make the free throws 7/10 of the time or 70%.
The answer would be that you are likely to make the free throws, so answer A.) is correct.
You miss a free throw 3/10 of the time is unlikely event. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, miss a free throw 3/10 of the time.
Here, 3/10 =0.3
The total probability is always equal to unity.
If the event is “certain” to happen, the probability will be 1.
If the event is “likely” to happen, the probability will be between 1/2 and 1.
If the event has an “equal chance” to happen or not, the probability will be 1/2.
If the event is “unlikely” to happen, the probability will be between 0 and 1/2.
You miss a free throw 3/10 of the time is unlikely event.
Therefore, option B is the correct answer.

Answers
Answer:
the nominator could be any number here
Step-by-step explanation:
what do you need ? the equation itself is true, if you put the same number in both places above 21.
any number is possible there, it will not change the equation.
so, again, I am not sure, what you need here.
let's write it with a variable to make my statements clearer :
9 + 1 x/21 = 10 x/21
that is true, because we can combine the whole numbers first giving us 9 + 1 = 10.
and then we add the fraction again (x/21).
again, you can put any number instead of x, and it will always be true.
example
9 + 1 4/21 = 10 4/21
