li writes the expression “half of the sum of 9 and a number.” Write an algebraic expression that is equivalent to Ali’s expression. Write a second algebraic expression that is different from, but equivalent to, your first expression. Respond in the space provided.
Answer:
Step-by-step explanation:
.......
Answer:
The expression will be : (x+9) /2
What is algebraic expression?An algebraic expression is an expression built up from integer constants , variables , and the algebraic operations.
Let us take the number to be : x
Now, ( half of the sum of 9 and a number ) will be : (x+9)/2
Dividing x and 9 with 2 we get,
the second expression which is different but equivalent to first will be :
=0.5 x + 4.5

The diameter of a spherical basketball is 10 inches.
What is the volume of the basketball2
Give the exact solution.
Volume
I NEED THE ANSWER FAST HELPP PLEASE
Answer:
Step-by-step explanation:
Rounded volume: 524 cubic inches.
Step-by-step solution:
The formula for the volume of a sphere is:
Where r is the radius of the sphere.
The radius is half the diameter, therefore it is r=10/2=5
We plug it into the formula and we get:
Then we get:
If we do it in our calculator we get 523.599 that rounded to the nearest whole is 524 cubic inches .

Use your answer from Part I to find the slope of a line going through each set of points. Then
describe the line as positive, negative, zero, or undefined. Show your work and explain your
answer.
A. (5, 7) and (-4,-2)
B. (1, 3) and (1, -10)
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
PLS HELP ME!!!!! Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Suppose M is the amount of money the students collect for selling R raffle tickets. Write an equation that reflects the relationship between M and R.
Answer: M=2.4R
Step-by-step explanation:
If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...
24/10=2.4
so now we can set up our equation...
M=2.4R
this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.
4x - 35 = 234
Solve for 'x'.
Answer:
X= 67.25
Step-by-step explanation:
4x-35=234
Add 35 to both sides
4x= 269
Divide both sides by 4
X= 67.25
Answer:
x = 67,25
Step-by-step explanation:
Here it is given that,
x is an unknown to know. Since we are intelligent students, we will bring the unknowns to the left limb, and the numbers known in the right limb.[tex]\:[/tex]
We can write this matematically as,
[tex]\rightarrow 4x - 35 =234[/tex]
Move the constant to the right,
[tex]\rightarrow 4x =234 + 35[/tex]
Add the numbers,
[tex]\rightarrow 4x =269[/tex]
Divide both sides of the equation by 4,
[tex]\rightarrow x =\frac{269}{4}[/tex]
We determine the value of x,
[tex]\rightarrow \underline {x=67,25}[/tex]
A textbook company states that the average time a student needs to take a quiz from its book is 30 minutes with a standard deviation of 3 minutes. A teacher using the book is not sure that this is correct for her classes and wants to check. She collects data on 10 random students and finds that the average time to take the quiz was only 25 minutes. As a result, the teacher performs a two-tailed hypothesis test with a significance level of 5%. Which conclusion is valid based on the results of the test
Answer:
We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.
Step-by-step explanation:
We are given;
Population mean; μ = 30 minutes
Population standard deviation; σ = 3 minutes
Sample size; n = 10
Sample mean; x¯ = 25
Significance level = 5% = 0.05
Let's define the hypotheses;
Null hypothesis; H0: μ = 30
Alternative hypothesis: Ha: μ ≠ 30
Let's find the test statistic;
z = (x¯ - μ)/(σ/√n)
z = (25 - 30)/(3/√10)
z = -5.27
From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;
p < 0.00001
This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
Answer:
A. Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
