Juanita borrowed $600 to purchase a new computer. She
was charged 7% interest for two years. She used the
simple interest formula to find the interest.
|=600(7)(2)
What error did Juanita make and how will her error affect
the interest she calculates? Explain.
Answer:
Forgot to turn the 7% into a 0.7... if you dont do that, then it will come out larger then it was supposed to be :)
Answer:
Sample response: Juanita did not change the 7% to the decimal 0.07. When she completes the problem as written, the interest will be greater than the money she borrowed.
Step-by-step explanation:
This is a sample response, be sure to change the wording up a bit.
can you find the radius
Answer:
radius is 6.5
I hope it's helps you

We all hate to bring change to a store. By using random numbers, we can eliminate the need for change and give the store and the customer a fair deal. Suppose you buy something for 20 cents. If the store generated a random number using the cash register (call the random number R), what rule could they use to decide whether you should pay $1 or $0 for the item
Answer:
Round off to closest value.
Step-by-step explanation:
In order to remove the requirement for change, every time the client buys a product for $0.20 the random number that lies between 0 and 1 would be produced also the same would be rounded to the closest value i.e. 0 or 1. In the case when 0 arise so the customer would not have to pay any amount but if 1 arise so the customer have to pay $1. So this type of method would remove the requirement for a minor change

Enter your answer in the box.
Do not use decimals in your answer.
Answer: 14x+74
Step-by-step explanation:
-6x+86-32x-12+52x=14x+74
-6x+86-32x-12+52x
=-6x-32x+52x+86-12
=14x+86-12
=14x+74
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The final expression after simplifying is 14x + 74.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x + 4 = 3 is an expression.
3 + 4x - 5 is an expression.
We have,
-6x + 86 - 32x - 12 + 52x
Add like terms.
-6x - 32x + 52x = 14x

Bert has 40% more jelly beans than Vicki. What fractional part of Bert's
jelly beans must be given to Vicki so that they each have the same number
of jelly beans? Express your answer in lowest terms.
Answer:
2/5
Step-by-step explanation:
If Vicki has 100 jelly beans then Bert would have 140. Bert would have to give 40 out of his 140 to Vicki or 40/100 -> 4/10 -> 2/5. Bert would have to give 2/5 of his jelly beans to Vicki.

Suppose that 3\%3%3, percent of over 200{,}000200,000200, comma, 000 books borrowed from a library in a year are downloaded. The librarians plan to take an SRS of 757575 books from the population of borrowed books to see what proportion of books sampled are downloaded. What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books
Answer:
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
3% of books borrowed from a library in a year are downloaded.
This means that [tex]p = 0.03[/tex]
SRS of 75 books.
This means that [tex]n = 75[/tex]
What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books
By the Central Limit Theorem
Mean: [tex]\mu = p = 0.03[/tex]
Standard deviation: [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197[/tex]
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
n times 5 is equal to 24
word in equation and solve for variable
Step-by-step explanation: Remember that "times" mean multiply.
So reading the problem from left to right, we have n times 5,
that's n multiplied by 5 or 5n, is means equals, 24.
So we have 5n = 24.
We want to solve our equation for n so we want to get
n by itself on the left side of the equation.
Since n is being multiplied by 5, we need to divide both sides
of the equation by 5 and we have n = 24/5.
Don't be nervous to check your answer back in
the original equation even if it is a fraction.
