Tia is going to a school where tuition and books cost $11,000. She has a scholarship that pays 100% of tuition. She has a grant for $1,000 Does she have enough to pay for tuition and books?
Answer:
Unknown, not enough information.
How much do the books cost?
norm has $25 from his birthday to start with and plans to add $7 each week
Answer:
Total amount = 7x + 25
Step-by-step explanation:
Assuming that week can be denoted by a variable, in this case, x. Also assume that the total amount owned is denoted by the variable, y.
Note that $25 is the constant, meaning that that amount will not change. Norm would technically have at least $25 regardless of how much week passes.
The amount that changes per week is the addition of $7.
Set the equation:
Total amount = ($7 per week x amount of week(s)) + starting amount (constant).
Total amount = 7x + 25

Leo wants to determine the average number of texts middle school students send in a day. Since all middle school students are enrolled in history, he randomly surveyed 4 students from each of Mr. Barnes’s eighth-grade history classes. Ms. Lopez and Mrs. Frank also teach eighth-grade history. What should Leo do to ensure his sample is representative of all middle school students?
He should take the sample as is because he randomly surveyed students in each of Mr. Barnes’s classes.
He should also take a sample from Ms. Lopez’s and Mrs. Frank’s classes so that each student has the same chance of being chosen.
He should also take a sample from each of the other history classes in all of the other grades in the middle school.
He should survey all the students in all the history classes to make sure he collects enough data.
Answer: C) He should also take a sample from each of the other history classes in all of the other grades in the middle school.
Step-by-step explanation:
In order for his sample to be representative of all middle school students Leo: C) Should also take a sample from each of the other history classes in all of the other grades in the middle school.
What is sample?Sample can be defined as the data that is randomly collected by a researcher so as to reach or draw a conclusion.
Since only one grade is being surveyed which is Mr. Barnes’s eighth-grade history classes, he should as well carryout the survey on Ms. Lopez and Mrs. Frank history class.
Inconclusion he should also take a sample from each of the other history classes in all of the other grades in the middle school.
Not only students in the 8th grade are in the middle school, there are other students in other grades who are in the middle school and are enrolled in history classes. Leo's sample is only from one grade of the middle school. In fact, including Ms. Lopez's and Mrs. Frank's classes in the selection of sample is not sufficient. Leo has to take a sample from the remaining grades to avoid making a wrong conclusion as a result of bias in the choice of data.
If the average of the following data is 8, what is value of b?
3, 9, 8, 5, 10, 4, 4, b
Answer:
The answer is b= 8

Bert is planning to open a savings account that earns 1.6% simple interest yearly. He wants to earn exactly $128 in interest after 2 years. How much money should he deposit?
To solve for the Principal amount, we will use the formula:
P = I / rt
P = principal amount; which is the amount that we will be solving for.
I = the interest accrued within the allotted time frame. ($160)
r = the interest rate percentage. (1.6%)
t = the time frame that the money will accrue interest. (2 years)
Before we can plug in the numbers into our formula, we need to convert our percent into a decimal. To do this, move the decimal two places to the left. This will leave us with 0.016. We'll use that for "r".
Let's plug in the numbers:
P = 160 / (0.016) (2)
Multiply your bottom numbers together for 0.016 x 2 =0.032
P = 160 / 0.032
Divide now.
160 ÷ 0.032 = 5,000.
This tells us that, Bert will need to deposit $5,000 into the savings account to earn $160 within 2 years with a 1.6% interest rate.

PLS HELP (answer isn't 1384.74 lol)
Answer:
1385mm squared
Step-by-step explanation:
Area of Circle formula: A = pi r^2
You need to divide 42mm by 2 since that is a diameter.
*Half of the diameter is the radius*
42/2 = 21
Now, do 3.14 multiplied by 21 to the power of 2.
Formula: A = 3.14 x 21^2
Do 21^2 first.
That shall be 441
Now do 3.14 x 441
1,384.74mm - That is your exact answer.
The directions tell you to round it to the nearest whole number
THAT IS 1385mm squared

The correct option is (C) and (D).
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
Given:
A spinner has 5 equally sized sections labeled A, B, C, D, and E.
As,
P(A)= P(B)= P(C)= P(D)= P(E)= 1/5, which is same.
The probability model for this situation is uniform.
Hence, The probabilities of the individual outcomes are the same.

The speed of the jet Alyssa flew on from Boston to London was 480 mph. On her return flight, the speed of the jet was 600 mph with a tail wind. What was Alyssa's average speed on the round trip? Round your answer to one decimal place.
P.S: The answer is not 540
Answer:
the ansere is -20
Step-by-step explana
The speed is given by the arithmetic mean. Then the jet Alyssa's average speed on the round trip is 540.
What is the average speed?The total distance covered by the particle or the body in a total time is called average speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the average speed formula
[tex]\rm v_{a} = \dfrac{v_1+ v_2}{2}[/tex]
The speed of the jet Alyssa flew on from Boston to London was 480 mph.
On her return flight, the speed of the jet was 600 mph with a tailwind.
Then the average speed of the jet will be
[tex]\rm v_{a} = \dfrac{v_1+ v_2}{2}\\\\v_{a} = \dfrac{480 + 600}{2}\\\\v_{a} = 540\ mph[/tex]
