Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)
Susan worked 30 hours one week. She deposited $70 in her savings account and had $140 left. How much does Susan earn per hour?
Hi!
Your answer would be: almost $5, but the actual amount is $4.67.
Reason being: when you divide $140 by 30, you get $4.67, and rounding to the nearest number, you get $5.
Therefore, the answer is $4.67
Hope this helps!

Suppose you are given four statements about a number: a) It is the number 9. b) It is a prime number. c) It is an even number. d) The number is divisible by 15. Only two statements out of four are true. What is the least possible positive value for the unknown number?
Answer:
30
Step-by-step explanation:
as 9 isnt divisible by 15 or even, it cant be true. it cant be a prime number and even so thats not true either. the number must be 30 because it is divisible by 15 and even and the least possible value.

A student memorized the statement the product of any rational number and any irrational number is irrational. Label this statement as true or false, and explain your reasoning. A) True. For example, 3 ·5 is irrational, 7 · 2 3 is irrational, and (π)·(−4) is irrational. B) False. Suppose an irrational times a rational = rational, then irrational = rational rational . This means irrational = rational, which is a contradiction.Thus an irrational times a rational = rational. C) True. Suppose an irrational times a rational = rational, then irrational = rational rational . This means irrational = rational, which is a contradiction.Thus an irrational times a rational = irrational. D) False. The rational number cannot be zero. Suppose an irrational times a nonzero rational = rational, then irrational = rational nonzero rational . This means irrational = rational, which is a contradiction. Thus an irrational times a nonzero rational = irrational.
Answer:
A) True. For example, 3 ·5 is irrational, 7 · 2 3 is irrational, and (π)·(−4) is irrational.

Answer: chart b
Step-by-step explanation:
2 is only a product of the outcomes 1/18 times
3 is only a product of the outcomes 1/18 times
4 is only a product of the outcomes 1/12 times
5 is only a product of the outcomes 1/18 times
6 is only a product of the outcomes 1/9 times
and so on
The chart that shows the probability distribution for the sum of the two numbers is chart B.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
When two dice are rolled, 36 equally likely outcomes are possible
The sum of the 36 outcomes are as follows: 2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12

n(2) = 1
n(3) = 2
n(4) = 3
n(5) = 4
n(6) = 5
n(7) = 6
n(8) = 5
n(9) = 4
n(10) = 3
n(11) = 2
n(12) = 1
The probability of the sums are given as follows:
p(2) = 1/36
p(3) = 2/36 = 1/18
p(4) = 3/36 = 1/12
p(5) = 4/36 = 1/9
p(6) = 5/36
p(7) = 6/36 = 1/6
p(8) = 5/36
p(9) = 4/36 = 1/9
p(10) = 3/36 = 1/12
p(11) = 2/36 = 1/18
p(12) = 1/36
Therefore, the chart that shows the probability distribution for the sum of the two numbers is chart B.

Six months ago you won $1,000,000 on a scratch-off lottery ticket and invested your winnings with a financial advisor at the investment firm Dewey, Lie, and Howe. The earnings on the investment are compounded monthly.You complain to the financial advisor that your returns after 6 months are inadequate and do not even cover the advisor's fees. The 6 monthly interest rates (in decimal form) have been R1 = -0.4, R2= 0.67, R3 = 1.0, R4 = -0.5, R5 = 0.2, R6 = -0.165.1. What is the total worth of your investment after 6 months?$The financial advisor responds that you shouldn't complain because the average return over the 6 months has been an impressive 13.4% (0.134 in decimal form). You angrily respond that the average return is not representative of the 6-month investment performance, and that the geometric mean should be used instead.2. What is the geometric mean of the above monthly returns? (express as a decimal; round off to 3 decimal places)geometric mean
Answer:
The total worth of the investment after 6 months is T = $ 1004004
The geometric mean of the above monthly returns is [tex]\= G = 0.001[/tex]
Step-by-step explanation:
From the question we are told that
The growth for each month are
R1 = -0.4, R2= 0.67, R3 = 1.0, R4 = -0.5, R5 = 0.2, R6 = -0.165
The amount invested is [tex]A = \$ 1,000,000[/tex]
The number period of the investment is 6 months
Generally the worth of the investment after each month is
[tex]G_i = G_p * (1 + R_i)[/tex]
Here [tex]G_p[/tex] is the worth of the investment the previous year
[tex]R_i[/tex] is the growth for that month
So considering the first month
[tex]G_1 = G_p (1 + R_1)[/tex]
Here [tex]G_p = A[/tex]
So
[tex]G_1 = 1000000 (1 -0.4)[/tex]
[tex]G_1 = 600000[/tex]
Considering the second month
Here [tex]G_p = 600000[/tex]
So
[tex]G_2 = 600000 (1 + 0.67)[/tex]
=> [tex]G_2 = 1002000[/tex]
Considering the third month
Here [tex]G_p = 1002000 [/tex]
So
[tex]G_3 = 1002000 (1 + 1)[/tex]
[tex]G_3 = 2004000 [/tex]
Considering the fourth month
Here [tex]G_p = 2004000 [/tex]
So
[tex]G_4= 2004000 (1 + -0.5)[/tex]
[tex]G_4= 1002000 [/tex]
Considering the fifth month
Here [tex]G_p = 1002000 [/tex]
So
[tex]G_5= 1002000 (1 + 0.2)[/tex]
[tex]G_5= 1202400 [/tex]
Considering the six month
Here [tex]G_p = 1202400 [/tex]
So
[tex]G_6= 1202400 (1 -0.165)[/tex]
[tex]G_6= 1004004 [/tex]
Generally the total worth of the investment after 6 months is T = $ 1004004
Generally the geometric mean of the monthly returns is
[tex]\= G = \sqrt[n]{ [(1 + R_1 ) * \cdots (1 + R_n)} ]-1[/tex]
Here n represents the number of months which has a value n = 6
So
[tex]\= G = \sqrt[6]{[(1+ (-0.4 )) * (1 + 0.67) * \cdots * (1 + (-0.165))]} - 1[/tex]
[tex]\= G = 0.001[/tex]

Step-by-step explanation:
A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mix A contains 35 pounds of phosphoric acid, 15 pounds of nitrogen, and 16 pounds of potash. Each cubic yard of mix B contains 14 pounds of phosphoric acid, 18 pounds of nitrogen, and 64 pounds of potash. The minimum monthly requirements are 840 pounds of phosphoric acid, 540 pounds of nitrogen, and 768 pounds of potash. If x is the number of cubic yards of mix A used and y is the number of cubic yards of mix B used, write a system of linear inequalities that indicates appropriate restraints on x and y. Find the set of feasible solutions graphically for the amounts of mix A and mix B that can be used.
Answer:
The answer is below
Step-by-step explanation:
Given that the minimum monthly requirements are 840 pounds of phosphoric acid, hence:
35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric acid
35x + 14y ≥ 840
The minimum monthly requirements are 540 pounds of nitrogen, hence:
15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen
15x + 18y ≥ 540
The minimum monthly requirements are 768 pounds of potash, hence:
16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash
16x + 64y ≥ 768
Also, x ≥ 0 and y ≥0.
Therefore the equations are:
35x + 14y ≥ 840
15x + 18y ≥ 540
16x + 64y ≥ 768
x ≥ 0 and y ≥ 0

Sixty percent of a class is girls. If here are 18 girls in a class, then how many total students are there?
Answer:
30 students
Step-by-step explanation: If 60% is 18, then 10% wold be 3. And we know that 10% multiplied by 10 is 100%. Therefore 3 multiplied by 10 should be euqal o the total amount of students. And since 10% times 3 is 30, there are 30 students in total.
Answer:
30 students
Step-by-step explanation:
We can do this question using direct proportion.
"If 18 girls represent 60%, how many students represent 100%?"
18/60=x100
x=18×100/60
30 students altogether.

Leon already knew 24 appetizer recipes before starting culinary school, and he will learn 2 new appetizer recipes during each week of school. After how many weeks of culinary school will Leon know a total of 100 appetizer recipes?
Answer: It will take him 38 weeks.
Step-by-step explanation:
We will model the situation by an equation.
Leon already knew 24 appetizer recipes so it will be permenant. He will learn to more each week so we can achieve the expression . 24 + 2x where x is the number of weeks.
If we want to know the number of weeks it will take him to learn 100 appetizer recipes then we will have to set the equation equal 100.
24 + 2x = 100 Now solve for x
-24 -24
2x = 76
x = 38

you deposit 2000 each year into an account earning 3% interest compounded annually. How much will you have in the account in 15 years?
Answer:
It should be $2,900
Step-by-step explanation:
First you convert the percentage to decimal form out of 100
3%/100 = 0.03
A = P(1 + rt)
A = 2000(1 + 0.03 x 15)
Which you should get $2,900 or $2,900.00 (which is pretty much the same thing)

"What is the general process for solving an equation with one variable?"...
Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.
Example:
2x+4=64
Add -4 to both sides to isolate the variable.
(2x+4)+(-4)=(64)+(-4)
Simplify.
2x=60
Divide both sides by 2 to isolate the variable on one side.
(2x)/2=(60)/2
x=30
