Step-by-step explanation:
448 rubber bands to make 12 rubber band bottles of the same size.
450 divided by 10 is about 45 rubber band per rubber band bottle.
This is nowhere near the the 116 rubber bands to make a rubber band ball.
If the are about the same size, we should use about the same number of rubber bands.
If he used about 100 rubber bands per rubber band bottle * 12 bottles, that would be about 1200 rubber bands.

(x^2+10x+26)/(x+6) How do you get the quotient and remainder
Answer:
quotient is x+4 and remainder 2.
Step-by-step explanation:
Given an polynomial of degree 2 and we are to divide it by x+6.
To find quotient and remainder
We can do synthetic division
When we divide by x+6 consider -6
and write on left. Write the coefficient 1 , 10, 26 inside
-6 1 10 26
x -6 -24
---------------------
1 4 2 =R
So remainder is 2 and quotient is x+4
Let us verify
(x+4)(x+6) = [tex]x^2+10x+24[/tex]
If we add the remainder we are getting the given expression.

Sarah had 12 free throw attempts during a game and made at least 75% of the free throws. What is the greatest number of free throws Sarah could have missed during the game.
Answer:
3
Step-by-step explanation:
25 percent of 12 is 3
Answer:
She missed 3 free throws.Step-by-step explanation:
According to the problem, Sarah's percentage of successful free throws is 75%, this means that she failed a 25% of the total. If the total free throws are 12, then:
[tex]12(0.25)=3[/tex]

A recipe for beef stew requires 1 and 3/4th pounds of meat.You are making 6 and 1/2 batches of the recipe. how much meat do you need?
Answer:
11.375 pounds
Step-by-step explanation:
1.75 * 6.5 = 11.375
11 and 3/8 pounds of meat are required in total.
The student is asking a multiplication problem that involves fractions. To find the amount of meat needed, we multiply the amount of meat required for one batch by the number of batches.
Step-by-Step Calculation
First, we must convert the fractions into improper fractions to simplify calculation. The recipe requires 1 and 3/4 pounds of meat, which is
7/4 pounds (since 1 pound is 4/4 pounds, we add 3/4 pounds to get 7/4 pounds).
Next, the number of batches is 6 and 1/2, which as an improper fraction is 13/2 batches.
To find the total amount of meat required, we multiply the pounds per batch by the number of batches: (7/4) pounds x (13/2) batches = (7/4) x (13/2) = (7 x 13) / (4 x 2) = 91/8 pounds.
Finally, convert 91/8 pounds to a mixed number: 11 and 3/8 pounds of meat are required in total.

If you apply the changes below to the linear parent function, F(x)=x, what is the equation of the new function? vertically compress by 1/4 flip over the y-axis
Final answer:
The new function after applying the given transformations to the linear parent function f(x) = x, results in f(x) = -1/4x, representing a combined vertical compression and reflection about the y-axis.
Explanation:
Starting with the linear parent function f(x) = x, we need to apply two transformations: a vertical compression by 1/4 and then a reflection over the y-axis. Applying a vertical compression by 1/4 means we multiply the output by 1/4, resulting in f(x) = (1/4)x.
To reflect the function across the y-axis, we replace x with -x, which gives us the new function f(x) = (1/4)(-x) or, simplified, f(x) = -1/4x. Therefore, the equation of the transformed function is f(x) = -1/4x.

Complete the point slope equation of the line through (-2,6) and (1,1)
Answer:
y-1 =( -5/3) (x-1)
Step-by-step explanation:
The point slope equation for a line is
y-y1 = m(x-x1)
where m is the slope and (x1, y1) is a point
We need to determine the slope
The formula for slope is
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are points
m = (1-6)/(1--2)
= (1-6)/(1+2)
=-5/3
The slope is -5/3
Now we can substitute the slope into the equation for a line. We can use either point. I will use (1,1)
y-y1 = m(x-x1)
y-1 =( -5/3) (x-1)
Answer:
y-1 =( -5/3) (x-1)
Step-by-step explanation:
The point slope equation for a line is
y-y1 = m(x-x1)
where m is the slope and (x1, y1) is a point
We need to determine the slope
The formula for slope is
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are points
m = (1-6)/(1--2)

=-5/3
The slope is -5/3

y-y1 = m(x-x1)
y-1 =( -5/3) (x-1)
It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day. Working at the same pace, how many days will it take 2 people to do the same work, if they are working 5 hours a day?
Answer:
It will take 2 people 10 days to complete the task.
Step-by-step explanation:
It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day, i.e., 10 people take 10 working hours to complete a task.
When number of people is decreased by 5 times, i.e., 10÷5=2, then the amount of working hours are increased by 5, i.e., 10×5= 50 hours.
If the 2 workers work 5 hours per day then they will require 10 days to complete the task of 50 hours.

HELP ASAP!!! WILL GIVE BRAINLIEST!!!!!The equation y = mx + b is used to express the equation of a line. Which solution is a correct way to solve this equation for x in terms of y?
To solve the equation y = mx + b for x, subtract b from both sides and then divide by m, resulting in x = (y - b) / m.
Explanation:To solve the equation y = mx + b for x in terms of y, you need to isolate x on one side of the equation. Here’s how you can do it step by step:
Start with the original equation y = mx + b.Subtract b from both sides of the equation to get y - b = mx.Divide both sides by m (assuming m ≠ 0) to solve for x which gives us (y - b) / m = x.Therefore, the equation solved for x in terms of y is x = (y - b) / m.

One characteristic of all linear functions is that they change by
1) equal factors over equal intervals
2) unequal factors over equal intervals
3) equal differences over equal intervals
4) unequal differences over equal intervals
The correct answer is:
3) equal differences over equal intervals
Linear functions exhibit a consistent rate of change over equal intervals, leading to equal differences between successive values of the function. This characteristic is fundamental to understanding linearity.
When graphed, linear functions form straight lines, and the slope of the line represents the rate of change or the coefficient of the independent variable. Regardless of the specific values of the function, the change in output over any fixed change in input (interval) remains constant.
This property is referred to as having equal differences over equal intervals. It contrasts with non-linear functions, where the rate of change varies across the function's domain, resulting in unequal differences over equal intervals.
Identifying and understanding this characteristic helps in recognizing linear relationships and interpreting their behavior in various contexts, from mathematics to real-world applications.

Based on the latest census there are 9860 students in a population of 62400 people. What percent of the total population is students?
Answer: 15.80%
Step-by-step explanation:
Given: Total population=62400
The total number of students=9860
To find the percent of the total population is students, we need to divide total population by total number of students and then multiply with 100, we get
The percent of the total population is students=[tex]\frac{9860}{62400}\times100[/tex]
[tex]=\frac{9860}{624}\\=15.80\%[/tex]
Hence, the percent of the total population is students is 15.80%.
Final answer:
To calculate the percentage of the total population that are students, divide the number of students (9860) by the total population (62400) and multiply by 100, resulting in approximately 15.8%.
Explanation:
To find the percentage of the population that are students, we use a simple formula where we divide the number of students by the total population and then multiply the result by 100. Applying this to the given numbers:
Percentage of students = (Number of Students / Total Population) × 100
Using the numbers provided:
Percentage of students = (9860 / 62400) × 100
Percentage of students = 0.15801282 × 100
Percentage of students = 15.801282%
Therefore, approximately 15.8% of the total population is students.
If the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs” what is the alternate hypothesis?
Answer:
“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.
Step-by-step explanation:
Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
We have to find the alternate hypothesis.
In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.
Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
i.e H0: [tex]x bar\geq 39 lbs[/tex]
So alternate hypothesis
Ha: [tex]x bar\leq 39 lbs[/tex]
