At a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes, how many vanilla cupcakes are at the party?
Answer:
8
Step-by-step explanation:
24 dividing by 3 equals 8.
The number of vanilla cupcakes at the party will be 8.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that at a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes.
The number of cupcakes will be calculated as:-
4 / 3 = 24 / V
V = ( 24 x 3 ) / 4
V = 18
Hence, the quantity of vanilla cups is 18.

Blank 1:
Answer:
0.367 = 36.7% probability that the student gets fewer than 2 questions correct
Step-by-step explanation:
For each question, there are only two possible outcomes. Either he guesses the correct answer, or he does not. The probability of guessing the correct answer on a question is independent of any other question. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
8 questions on it
This means that [tex]n = 8[/tex]
4 choices.
One of them is correct, which means that [tex]\pi = \frac{1}{4} = 0.25[/tex]
What is the probability that the student gets fewer than 2 questions correct?
This is
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{8,0}.(0.25)^{0}.(0.75)^{8} = 0.1[/tex]
[tex]P(X = 1) = C_{8,1}.(0.25)^{1}.(0.75)^{7} = 0.267[/tex]
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.267 = 0.367[/tex]

Step-by-step explanation:
Fatuma recently hired an electrician to do some necessary work. On the final bill, Fatuma was charged a total of $708. $480 was listed for parts and the rest for labor. If the hourly rate for labor was $57, how many hours of labor was needed to complete the job?
Answer:
4 hours.
Step-by-step explanation:
First we need to subtract $480 from $708.
$708-$480= $228.
Because the hourly rate is $57 we need to divide 228 by 57.
228÷57=4
The answer is 4 hours.
Find the slope of the line that passes through the points (11,13) and (7,10).
Answer:
m = 3/4
Step-by-step explanation:
The horizontal change in x is 4 and the vertical change 3. The slope is therefore m = rise / run = 3/4.
Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in / y change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=10−(13)/7−(11) Simplify.
m=34

Make a system of equations, try to solve, and then see which statements apply.
let x be the cost of a DVD and y be the cost of a video game
Then you would have:
2x + y = 12
4x + 2y = 24
from turning the words into equations.
Now, solve:
first, multiply the first equation by 2
2x + y = 12 --> 4x + 2y = 24
Then, subtract the two equations:
4x + 2y = 24
- (4x + 2y = 24)
0 = 0

The difference between a number and 3 is no more than 2
Answer:
Any number 5 and below
Step-by-step explanation:
We are given the expression that the difference between a number and 3 is no more than 2. Break down the expression and spot the key word of "difference," therefore meaning that the unknown number "x" and 3 is equal or less than 2. We can create the algebraic expression of x - 3, now since the answer must equal 2 or below 2, we can create the inequality :
x - 3 ≤ 2
Now the only numbers that are allowed to be inputted here is 5 and below.
The solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.
Let us denote the number as "x," we can express the given statement as an inequality:
|x - 3| ≤ 2
This inequality states that the absolute value of the difference between x and 3 is less than or equal to 2.
If x - 3 ≥ 0 (x ≥ 3)
In this case, the absolute value can be removed:
x - 3 ≤ 2
x ≤ 2 + 3
x ≤ 5
and if x - 3 < 0 (x < 3)
The absolute value becomes negative:
-(x - 3) ≤ 2
x + 3 ≤ 2
x ≤ 2 - 3
x ≤ -1
x ≥ 1
Combining the results from both cases, we have:
x ≤ 5 or x ≥ 1
Therefore, the solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.

Given the function g(x)= -x^2 + x + 5, determine the average rate of change of the function over the interval -4 ≤ x ≤ 3.
Answer:
The average rate of change is 2.
Step-by-step explanation:
We are given the function:
[tex]g(x)=-x^2+x+5[/tex]
And we want to find the average rate of change over the interval:
[tex]-4\leq x\leq 3[/tex]
The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.
Our first endpoint is given by:
[tex]g(-4)=-(-4)^2+(-4)+5=-15[/tex]
And our second endpoint is given by:
[tex]g(3)=-(3)^2+(3)+5=-1[/tex]
This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:
[tex]\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2[/tex]
The average rate of change is 2.
let m represent the number of children playing soccer. those children are separated into four equal groups. write an expression for the number of children on each team. what is the answer to this does anyone know?
Answer:
m/4
Step-by-step explanation:
m is how many children are playing.
They are separated into 4 groups. Making it m(how many people are playing), out of 4.
For example, if m=12, then it would be 12/4, so 3 children will be in each group.
