Step-by-step explanation:
Firstly, notice that this shape is composed of ³/₄ of a circle and ¹/₂ of a square;
The lower left part is the ¹/₂ square, with only 2 sides (a left and lower side) of length 3 units;
The perimeter of this part of the shape is simply the sum of the two sides:
3 + 3 = 6
The remaining part is the ³/₄ circle, which has a radius of 3 units;
The circumference of a circle is found by the formula:
πd
d = diameter = 2 × radius
We only have ³/₄ of the circle, however, so we only have ³/₄ the circumference:
³/₄ × π(2(3)) = ³/₄ × 6π
= ⁹/₂π (or, equally, 4.5π)
So the total perimeter is the sum of the perimeter of the ¹/₂ square and the ³/₄ circle:
4.5π + 6

How many solutions does the system formed by x-y=6 and ay-ax+6a=0 have for a nonzero number a? Explain.
Answers
Answer: infinitely many
Step-by-step explanation:
Just rearrange the second equation:
a(y - x + 6) = 0
y - x + 6 = 0
y - x = -6
x - y = 6
You have two equations that are identical. The number of (x,y) pairs satisfying "both" equations is just the number of pairs satisfying the first one. (Think about it, satisfying one is satisfying both.)
There are infinitely many (x,y) pairs satisfying x - y = 6, so answer is "infinitely many solutions."

Splinter wrote a three-digit number on the board.
Then he asked each of the four Teenage Mutant Ninja Turtles (Leonardo, Raphael, Donatello, and
Michelangelo) to count the number of letters in his name. (Donatello has 9 letters in his name.)
Splinter said that for each turtle, the number on the board minus the number of letters in the turtle's
name is evenly divisible by the number of letters.
Each turtle confirmed that Splinter was right.
Find the number Splinter wrote on the board.
Answers
The three-digit number that Splinter wrote down is:
504Response IdentificationTo solve the exercise, you must first count the number of letters in the names of each of the ninja turtles:
Leonardo: 8 lettersRaphael: 7 lettersDonatello: 9 lettersMichelangelo: 12 lettersTherefore, a three-digit number must be found that is divisible by 7, 8, 9 and 12. Therefore, the number 504 is proposed, since:
504 / 7 = 72504 / 8 = 63504 / 9 = 56505 / 12 = 42And even if the same number of letters is subtracted, the number would still be divisible by that number of letters.

g True or False: We will not have omitted variable bias if we leave out a RHS variable that affects the LHS variable, provided there is no correlation between the omitted RHS variable and the included RHS variables.
Answers
Based on the information given, it should be noted that we will have an omitted variable bias, therefore, it's true.
What is an omitted variable?An omitted variable simply occurs when a statistical model that occurs when one or more relevant variable is left out.
It should be noted that we will have omitted variable bias if we leave out a RHS variable that affects the LHS variable, even in a situation where there is no correlation between the omitted RHS variable and the included RHS variables.
For omitted variable bias to occur, it should be noted that the omitted variable will be correlated with the included regressor.

a) What is the landing space per step (in inches, rounded to the nearest inch)?
b) Find the vertical rise from the 1st floor to the 2nd floor (in feet, rounded to the nearest foot).
Answers
The landing space per step is 14 inches while the vertical rise is 13 feet.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and the angles of a right angled triangle.
From the question:
Angle of elevation = 41°
Let d represent the landing space per step, hence using trigonometric ratio:
tan(41) = 12 inches / d
d = 14 inches
Also, let h represent the vertical rise, hence:
tan(41) = h / 15 feet
h = 13 feet
The landing space per step is 14 inches while the vertical rise is 13 feet.

6. 1,000 people were given a survey about their favorite pizza place in NYC. 200 said Lombardi's and the rest said Patsy's. a. What percent of the people surveyed said Lombardi's? b. What percent of the people surveyed said Patsy's?
Answers
Answer:
A = 20%
B = 80%
Step-by-step explanation:
200/1000 people said Lombardi's, or:
since 1,000 = 100
and 200 = 20
then we can simplify this to
20/100 0r 20%
and if 100 people to the survey and 20/100 said Lombardi's,
that means 80% must have said Patsy's, because,
100 - 20 is the 80 percent of people who didn't vote for Lombardi's, and since Patsy's is the only other option, that means the other 80% voted for Patsy's.
So
20% said Lombardi's
and
80% said Patsy's!
to be honest, I think I like Patsy's more as well.

Drag each table into the box to correctly classify it.
Linear
Nonlinear
Answers
Answer:
1. Nonlinear
2. Nonlinear
3. Linear
Step-by-step explanation:
Hello there!
To solve this question, let's figure out a ratio of how much an x variable goes up by how much the y goes up. If it is a linear function (meaning a straight line), this ratio should stay consistent throughout the whole data plot.
For the first one, we can see that x is going up by 1, and so is y. But on the second to last, it jumps up once on the x value by 1, but y went up by two. This is not a consistent ratio and is considered nonlinear.
For the second one, we can see that for every x value going up 1, the y goes up by 1 too, as seen between the transition from the x values 1 to 2. However, when it goes from 2 to 4, the correct y value, if linear, should be 5.8. This is nonlinear.
The last one says that when x goes up by one, y value decreases by 2. this stays consistent all around and is linear.
