The definition of Sample Space = a list of all possible outcomes
3. List the sample space for each chance experiment.
a. flipping a coin
b. selecting a random season of the year
c. selecting a random day of the week
Answer:
A = 2 outcomes B = 4 outcomes C = 7 outcomes
Step-by-step explanation:
A has two outcomes because when you flip a coin you can only land on heads or tails
B has four outcomes becuase when picking a random season there are only four possible seasons to be picked.
C has seven outcomes becuase when picking a random day of the week there are only 7 possible days that can be picked,

If the pointer in the figure is spun twice, find the probability that the pointer lands on yellow (Y) both spins.
Answer: The probability of the pointer lands on red(R) both spin =
Step-by-step: The number of parts = 6
The pointer is spun twice.
To find the probability of the pointer lands on red(R) both spin.
Formula
Probability of an event = number of required outcomes ÷ the total number of outcomes.
P(A and B) = P(A)×P(B)
Now,
For one spin,
A = RED comes.
For second spin,
B = RED comes
So,
P(A) = and P(B) =
Then,
P(A and B) = × =
Hence, the probability of the pointer lands on red(R) both spin =

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y=-x^2+73x-520
y=−x
2
+73x−520
Answer:
36.5
Step-by-step explanation:
y= -x²+73x-520
which can be represented as ax²+bx+c
a= -1, b= 73, c = -520
for maximum value of y,
the formula is
c - (b² / 4a)
= -520 - (73² / 4×(-1))
= -520 - (5329 / -4)
= -520 + 1332.25
= 812.25
Solving for x,
812.25 = -x²+73x-520
or, x²-73x+ 1332.25 = 0
Solving,
x= 36.5

Business owners use percents to calculate markup, discount, and sales tax. A shoe store owner buys a pair of shoes for $20. There is a sale on the item for 20% off.
Answer:
$16
Step-by-step explanation:
Given data
The cost price of the shoe= $20
Discount = 20%
Let us find the amount of the 20% discount
=20/100*20
=0.2*20
=$4
Hence the selling price will be
=20-4
=$16
What would be the volume of a sphere if the radius is 6 in? Round to nearest tenth if needed
Answer:
904.8cm
Step-by-step explanation:
The volume of a sphere is given as
[tex] \frac{4}{3}\pi {r}^{2} [/tex]
There is only one variable, the radius, which we are given in the problem.
since the radius is 6 cm, we can plug that in to the formula
[tex] \frac{4}{3} \pi {6}^{2} [/tex]
Put this into the calculator, and we see that the volume is 904.8cm rounded to the nearest tenth.

Can someone explain to me how Slope Rise over Run works? I just don’t understand it no matter how many times I look into it.
Answer:
slope= rise over run means divide rise by run
Answer:
when there is a linear equation and line. first, find where you see a point that has whole numbers. graph them or circle them. Next, go to point to pint using the lines. do not use the slanted line. go up (rise) and count how many boxes you passed (be careful it could go by 2's) and then go across to the other point (run). count how many boxes you passed. now you put the up number or rise number over the run number. Rise/run. you'll get a fraction, simplified it if needed.
or do slope form which is just find 2 points that have whole numbers. Label the first one (x1,y1) and the second one (x2,y2) the you do (Y2 - Y1) over (X2 - X1). you'll get a fraction and you'll simplified it if needed

Find the length of side x in simplest radical form with a rational denominator.
Answer: 10
Step-by-step explanation:
a 30° - 60° - 90° triangle has a side ratio of 1:√3: 2, meaning the side length across from the 30° is 1, the side length across from 60° is √3, and the side length across from 90° is 2
if you multiple the 1 * 5 = 5 (the 5 side length in the diagram), then also multiple (5 * √3 = 5√3) and (2 * 5 = 10)
since you're looking for the hypotenuse (the length across the 90°), the answer would be 10 (2 * 5 = 10)
*this method can work for any 30° - 60° - 90° triangle
you can also use trig:
sin (30°) = [tex]\frac{5}{x}[/tex] (now just solve for x)
x * sin (30°) = 5
x = [tex]\frac{5}{sin(30)}[/tex]
x = [tex]\frac{5}{1/2}[/tex] ( because sin (30°) = 1/2 )
x = 5 * [tex]\frac{2}{1}[/tex] = 10
*either method works!

but I'm not sure how to get there...
Step-by-step explanation:
9 + y^2 = 49
y^2 = 40
y = √40 = 2√10
4.5/3 = 2√10/5x
22.5x = (3) 2√10
22.5x = 6√10
x = 6√10/22.5 = 3√10/11.5

which of the following statements are true
A tangent line is perpendicular to the radius of a circle at the point of tangency.
A tangent line is perpendicular to the diameter of a circle at the point of tangency.
A tangent line is the perpendicular bisector of the radius of a circle.
A tangent line intersects a circle at one point.
A tangent line intersects a circle at two points.
Every circle has exactly one tangent line to that circle.
The tangent line and radius or diameter of the circle intersect at a right angle and the tangent intersects the circle at a single point only. Then the correct option is A, B, and D.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The tangent line and radius or diameter of the circle intersect at a right angle.
And the tangent line intersects the circle at a single point only.
The number of the tangent line depends on the point from which the tangent is drawn.

Suppose you know the minimum, lower quartile, median, upper quartile, and maximum values for a set of data. Explain how to create a box plot for the data set.
NO LiNKS OR BE REPORTED
Answer:
For some sets of data, some of the largest value, smallest value
, first quartile, median, and third quartile may be the same. For instance, you might have a data set in which the median and the third quartile are the same. In this case, the diagram would not have a dotted line inside the box displaying the median. The right side of the box would display both the third quartile and the median. For example, if the smallest value and the first quartile were both one, the median and the third quartile were both five, and the largest value was seven, the box plot would look like:
In this case, at least
25
25
% of the values are equal to one. Twenty-five percent of the values are between one and five, inclusive. At least
25
25
% of the values are equal to five. The top
25
25
% of the values fall between five and seven, inclusive.
Answer:
First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.
Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.
Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.
Voila, my friend. You have a box plot.

What is the value of each variable?
Answer:
∠a = 1/2(95) = 47.5°
∠b = 90°
arc = (180 - 47.5 - 90)(2) = (42.5)(2) = 85°
Question 4 In AABC, what is the measure of ZC?
Answer:
C = 36°Explanation:
180 = 6x + 2x + 2x
180 = 10x
x = 180/10
x = 18
C = 2x
C = 18×2
C = 36°
