The data represents the semester exam scores of 8 students in a math course. {51,91,46,30,36,50,73,80} What is the five-number summary?
Answer:
minimum = 30, Q1 = 36, median = 50.5, Q3 = 80, and maximum = 91.
Step-by-step explanation:
We are given the following data set for the exam scored of 8 students in a math course and we are to find the five number summary:
51, 91, 46, 30, 36, 50, 73, 80
Step 1: For that, we first need to rearrange in an ascending order:
30, 36, 46, 50, 51, 73, 80, 91
Step 2: Now we will spot the smallest and largest number in the data.
Smallest number: 30
Largest number: 91
Step 3: Finding the median (middle number) now:
Median = 50+51/2 = 50.5
Step 4: Placing parenthesis around the number before and after the median values:
(30, 36, 46) 50, 51 (73, 80, 91)
Find Q1 (median in the lower half of the data) and Q3 (median for the upper half of data):
Q1 = 36
Q3 = 80
Five step summary:
minimum = 30, Q1 = 36, median = 50.5, Q3 = 80, and maximum = 91.
Answer:
Minimum = 30, Maximum = 91, Median = 50.5, Q₁ = 36, Q₃ = 80
Step-by-step explanation:
We have to find the five-number summary of the given data represents the semester exam scores of 8 students in a math course.
The five-number summary includes 5 items:
1. The minimum
2. Q₁ (First quartile)
3. Median
4. Q₃ (Third quarlile)
5. The maximum
First we put the numbers in ascending order (lowest to highest)
30, 36, 46, 50, 51, 73, 80, 91
Now find the minimum and maximum from your data set.
Minimum = 30 and Maximum = 91
Now find the median, median is the middle number. But we have 50, 51 two middle numbers so we take the median of those numbers =
Median = [tex]\frac{(50+51)}{2}[/tex] = 50.5
Median = 50.5
Now place parenthesis around the numbers before and after the median values
30, 36, 46, 50, 51, 73, 80, 91
Median of lower half of the data Q₁ = 36
Median of upper half of the data Q₃ = 80
Five-number summary found
Minimum = 30, Maximum = 91, Median = 50.5, Q₁ = 36, Q₃ = 80

Step-by-step explanation:
Given
y = [tex]3^{x}[/tex] and (- 3, y) is a point on the graph, then
y = [tex]3^{-3}[/tex] = [tex]\frac{1}{3^{3} }[/tex] = [tex]\frac{1}{27}[/tex]

A total of 20 quarters and nickels add up to $4.00. How many nickels are there?
Answer:
5 nickels
Step-by-step explanation:
You can setup and solve a system of equations, or you can solve by trial and error until you get the correct answer.
Here is the solution by trial and error.
If all 20 coins are quarters, the value is 20 * $0.25 = $5
That is too much value.
Let's try 16 quarters. 16 quarters are worth 16 * $0.25 = $4.
That is the correct value, but it is only with quarters, and only 16 of them.
We need fewer quarters than 16.
Try 12 quarters: 12 * $0.25 = $3.00
The number of nickels is: 20 - 12 = 8
8 nickels are worth 8 * $0.05 = $0.40
12 quarters and 8 nickels are worth $3.00 + $0.40 = $3.40
There are 20 coins, but the value is too low.
The number of quarters is between 12 and 16.
Try 14 quarters and 6 nickels:
14 * $0.25 + 6 * $0.05 = $3.50 + $0.30 = $3.80
We are closer to $4 but not there yet.
Try 15 quarters and 5 nickels.
15 * $0.25 + 5 * $0.05 = $3.75 + $0.25 = $4
The total value is $4 and there are 20 coins. This is the answer.
15 quarters and 5 nickels works.

Which line represents the line that passes through (3/2-1/2) and has a slope of 1
Step-by-step explanation:
The point-slope of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
We have
[tex]m=1\\\\\left(\dfrac{3}{2},\ -\dfrac{1}{2}\right)\to x_1=\dfrac{3}{2},\ y_1=-\dfrac{1}{2}[/tex]
Substitute:
[tex]y-\left(-\dfrac{1}{2}\right)=1\left(x-\dfrac{3}{2}\right)[/tex]
[tex]y+\dfrac{1}{2}=1\left(x-\dfrac{3}{2}\right)[/tex] → the point-slope form
Convert to the slope-intercept form:
[tex]y+\dfrac{1}{2}=x-\dfrac{3}{2}[/tex] subtract 1/2 from both sides
[tex]y=x-\dfrac{4}{2}[/tex]
[tex]y=x-2[/tex] → the slope-intercept form
We are creating a new card game with a new deck. Unlike the normal deck that has 13 ranks (Ace through King) and 4 Suits (hearts, diamonds, spades, and clubs), our deck will be made up of the following.
Each card will have:
i) One rank from 1 to 15.
ii) One of 9 different suits.
Hence, there are 135 cards in the deck with 15 ranks for each of the 9 different suits, and none of the cards will be face cards! So, a card rank 11 would just have an 11 on it. Hence, there is no discussion of "royal" anything since there won't be any cards that are "royalty" like King or Queen, and no face cards!
The game is played by dealing each player 5 cards from the deck. Our goal is to determine which hands would beat other hands using probability. Obviously the hands that are harder to get (i.e. are more rare) should beat hands that are easier to get.
a) How many different ways are there to get any 5 card hand?
The number of ways of getting any 5 card hand is
Answer:
Step-by-step explanation:
There are 5 cards we are selecting out of 135 cards so how many ways can we draw 5 cards at a time (w/o replacement)
There are 135 ways to choose the first card.
There are then 134 ways to choose the second card.
There are then 133 ways to choose the third card.
132 to choose the 4th
131 to choose the 5th.
Now multiply those giving 135*134*133*132*131 or you could have just said
135 P 5.
In case you don't know P means permutation.
The mathematics behind determining the number of different ways to get any 5 card hand from a deck of 135 cards involves combinatorics. Specifically, the combinations formula is used, which is C(n, r) = n! / [(n-r)!r!]. In this case, n is 135 (the total number of cards) and r is 5 (the number of cards drawn).
Explanation:The subject of this question concerns probabilities in the game theory section of mathematics, specifically revolving around understanding the combinatorics of card hands in a uniquely structured card game.
Using combinatorial mathematics, the number of ways to get any 5-card hand from a deck of 135 cards can be calculated by using the combinations formula which is: C(n, r) = n! / [(n-r)!r!]. In this instance, 'n' represents the number of total outcomes (135 cards) and 'r' is the number of outcomes chosen at a time (5 cards).
So to find the number of 5-card hands, you would calculate it as follows:
C(135, 5) = 135! / [(135-5)!5!]
The factorial of a number, denoted as '!', is the product of the number and all the consecutive numbers below it down to 1. So 5! = 5*4*3*2*1. Calculating this large of a number directly can be a bit tricky, but there are online tools that can help!

Line n has no x-intercept and it’s y-intercept is (0,-4)
Answer:
y = -4Step-by-step explanation:
If the line has no x-intercept, then it's a horizontal line with equation
[tex]y=a,\ a\neq0[/tex]
The line passes through the point (0, -4). Therefore the equation of this line is:
[tex]y=-4[/tex]
Answer:
y = 4
Step-by-step explanation:
Since the line has no x-intercept, this means that the line has a slope of 0, meaning it is a horizontal line. So with the equation y = mx + b, mx cancels out to 0 because there is no slope. This leaves y = b, where b = 4. So the answer is y =4
Consider the function g(x)=10/x
Answer:
The correct answers are:
(1) The vertical asymptote is x = 0
(2) The horizontal asymptote is y = 0
Step-by-step explanation:
(1) To find the vertical asymptote, put the denominator of the rational function equals to zero.
Rational Function = g(x) =
Denominator = x = 0
Hence the vertical asymptote is x = 0.
(2) To find the horizontal asymptote, check the power of x in numerator against the power of x in denominator as follows:
Given function = g(x) =
We can write it as:
g(x) =
If power of x in numerator is less than the power of x in denominator, then the horizontal asymptote will be y=0.
If power of x in numerator is equal to the power of x in denominator, then the horizontal asymptote will be y=(co-efficient in numerator)/(co-efficient in denominator).
If power of x in numerator is greater than the power of x in denominator, then there will be no horizontal asymptote.
In above case, 0 < 1, therefore, the horizontal asymptote is y =

Answer:
m angle BOC 120
m angle AOB 205
Step-by-step explanation:
So you are given mangle AOC+mangle BOC=mangle AOB.
mangle means measure of angle.
Let's do some substituting into our equation.
85+2x+10=4x-15
Solve for x... First I'm going to combine the like terms on the left hand side:
95+2x=4x-15
Add 15 on both sides
110+2x=4x
Subtract 2x on both sides
110 =2x
Divide both sides by 2
110/2 =x
x =110/2
x =55
So Recall mangle BOC=2x+10 =2(55)+10=110+10=120
And you also have mangle AOB=4x-15=4(55)-15=220-15=205
One x-intercept of a parabola is at the point (-3,0). Use the factor method to find the other x-intercept for the parabola defined by this equation:

Separate values with a comma
Answer:
The other x-intercept is (-2,0)
Step-by-step explanation:
-x^2-5x-6
-(x^2+5x+6)
We know x=-3 is a x-intercept so x+3 is a factor
-(x+3)( )
The other factor has to be x+2 since 3(2)=6 and 2+3=5
So -x^2-5x-6 is the same as -(x+3)(x+2)
Which means the other x-intercept is (-2,0)
