Answer:
You are correct it is not a function
Step-by-step explanation:
The reason is if you look in the x place (x,y) that is the input in this situation and you know a function can only have one output for each input and in this case we see that -3 has two outputs 1 and 5. Also -3 and 3 are two different inputs so if it was a debate between those two it would be a function.

You want to start your own business so you borrow $50,000 from the bank to pursue your dreams. You borrow it for 5 years at 3.2% simple interest rate. What is the interest INTEREST owed?
Answers
Answer:
$8000
Step-by-step explanation:
[tex]I=PRT[/tex] (I = interest, p = principal, r = interest rate, t = time. This only applies to simple interest)
[tex]I=\$50000\times3.2\%\times5[/tex] (assuming that it is [tex]3.2\%[/tex] p.a)
[tex]I=\$8000[/tex]
∴ The interest owed is $8000.

The number of deaths of children ages 1 to 14 in 1985 compared to 1991 for 10 states was gathered. (10 points) State Number of Child Deaths in 1985 Number of Child Deaths in 1991 1 33 51 2 53 33 3 58 51 4 73 44 5 88 89 6 130 142 7 212 195 8 213 215 9 275 269 10 313 312 Part A: Determine and interpret the LSRL. (3 points) Part B: Predict the number of child deaths in 1991 for State 11 if the number in 1985 was 65. Show your work. (3 points) Part C: Calculate and interpret the residual for State 11 if the observed number of deaths in 1991 was 42. Show your work. (4 points)
Answers
Solution :
From the output of regression equation given by
Number of death of children in 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]
Now, number of death of children in the year 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]
For x = no. of deaths of children in the year 1985 = 65
So substituting in the regression equation,
No. of deaths of children in year 1991 = [tex]$-5.21226+1.003538 \times 65$[/tex]
= [tex]$60.01771$[/tex]
≈ 60
Now residual = [tex]$\text{observed y - predicted y}$[/tex]
= [tex]$42-60$[/tex]
[tex]$-18$[/tex]
Part(a): Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
Part(b):
The number of child deaths in 1991 is 60.
Part(c): The observed is -18.
Part(a):
The given data can be solved by excel as,
From the output regression equation is,
Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
Part(b):
Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
For x=Number of child deaths in 1985=65
Number of child deaths in 1991 is,
[tex]-5.21226+1.003538\times65=60.01771\\=60[/tex]
Part(c):
Residual=observed y-predicted y
=42-60

Seven less than 4 times the square of a number is 18. Find the two numbers.
Answers
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

\therefore 84\degree + x\degree +x\degree = 180\degree \\
\therefore 84\degree + 2x\degree = 180\degree \\
\therefore 2x\degree = 180\degree - 84\degree \\

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original price? What is the new price for the pair of shoes? (Hint two answers!)
Answers
Answer:
a) What is the amount off the original price?
= $8.4
b) What is the new price for the pair of shoes?
= $33.6
Step-by-step explanation:
a) What is the amount off the original price?
We are told that:
The sale price is 20% off the original price.
Original price = $42
Hence:
$42 × 20%
$42 × 20/100
= $8.4
b) What is the new price for the pair of shoes?
The new price =
0riginal price - Amount off the original price
= $42 - $8.4
= $33.6
The original price = $33.6

For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.
Step-by-step explanation:
There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.
