Answer:
C
Step-by-step explanation:
You have 2 totals so the number of males + females = 127 so x + y = 127
Then there are 23 more males than females, it did not say 23 times more so B is out, so the female number + 23 = male number so y + 23 = x
Therefore letter C is the answer.
1. Li rolls a special dice that has 12 sides labeled 1 through 12, then flips a penny. What is the probability, written as a simplified fraction, that she rolls a multiple of 3 and flips tails? 2. A bag contains 5 red marbles, 6 green marbles, and 3 blue marbles. If Cymra draws a marble, puts it back in the bag, then draws another marble, write a multiplication problem you would use to find the probability that both marbles drawn will be red. 3. If Cole flips a coin three times, what is the probability that he will flip three tails in a row? 4. Based on collected data from the past 5 basketball practices, Linda has a 32% for making her free throws. If she shoots 175 more times, how many will she expect to make based on her percentage? !!! DUE IN 18 MINS !!!
Answer:
1. The probability that she throws a multiple of 3 and flips tails is 1/6
2. The probability that Cymra draws a red marble put it back and draws a red marble again is 25/196
3. The probability that Cole flips three tails in a row, P(3T) is 1/8
4. The number of shots Linda is expected to make if she takes 175 shots is 56
Step-by-step explanation:
1. The number of sides on the special die Li rolls = 12 sides
The numbers on the die are 1 through 12
The number of faces on the penny = 2 (heads and tails)
The number of multiples of 3 on the die = 3, 6, 9, and 12 = 4
The probability that she throws a multiple of 3, P(3) = 4/12 = 1/3
The probability that she flips tails rather than heads = 1/2
∴ The probability that she throws a multiple of 3 and flips tails = 1/3 × 1/2 = 1/6
2. The number red marbles in the bag = 5
The number green marbles in the bag = 6
The number blue marbles in the bag = 3
The total number of marbles in the bag = 5 + 6 + 3 = 14
The probability that Cymra draws a red marble put it back and draws a red marble again is given as follows;
The probability with replacement of picking two red marbles = 5/14 × 5/14 = 25/196
3. The probability that Cole flips three tails in a row P(3T) = (1/2)×(1/2)×(1/2) = 1/8
The probability that Cole flips three tails in a row, P(3T) = 1/8
4. The percentage of times Linda makes her free throws in the past 5 basketball practices = 32%
The number of shots she is expected to make if she takes 175 shots = 175 × 32/100 = 56.
Each base in this oblique prism is a right triangle.
What is the volume of the figure?
Answer:
66 cm³
Step-by-step explanation:
From the diagram,
Volume of the prism(v) = Area of the base (A)×Height(h)
v = A×h............... Equation 1
But,
A = bh/2.................... Equation 2
Where b = base of the triangle, h = height of the triangular base.
Substitute equation 2 into equation 1
v = (bh/2)H.................... Equation 3
Also for the diagram,
Given; b = 3 cm, h = 4 cm, H = 11 cm
Substitute these values into equation 3
v = (3×4×11)/2
v = 132/2
v = 66 cm³

Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
A pizza has 3,000 calories. If the pizza is cut into 8 slices, how many calories are in 3 slices of pizza?
Answer:
1125 calories
Step-by-step explanation:
3000 divided in 8 slices is 375 calories per piece.
3 pieces with 375 cals per 1125
Answer:
1125 calories
Step-by-step explanation:
Find how many calories are in one slice by dividing 3000 by 8:
3000/8
= 375
Find how many calories are in 3 slices by multiplying 375 by 3
375(3)
= 1125
So, in 3 slices of pizza, there are 1125 calories

Which equation below represents a line with a slope of - 2/3 that passes through the point (-4.5 , 10)?
A. y = - 2/3 x + 10
B. y = - 2/3 x +2.7
C. y = - 2/3 x + 7
D. y = - 2/3 x + 13
pls explain the answer if possible ^^
Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form: [tex]-4\frac{1}{2}[/tex]. Substitute [tex]-4\frac{1}{2}[/tex] for x and 10 for y in the equation, then solve:
[tex]y = -\frac{2}{3} x+7\\\\10 = -\frac{2}{3} (-4\frac{1}{2} )+7\\10 = -\frac{2}{3} (-\frac{9}{2})+7\\10 = 3+7\\10 = 10[/tex]
10 does equal 10, so this is a true statement. Option C is the right answer.

Taka is playing a game of darts. She scores 52 positive points. She gets a −3 score each time she misses the board. Her final point total is 37. Write and solve an equation to find out how many times she missed the board, x. Enter the correct answers in the boxes.
Answer:
she missed 5 times
Step-by-step explanation:
So she has 52 points already and the final amount was 37.
so each miss is -3 so we can make the amount with “x”
51-3x=37
SOlve and you would get 5 misses
There are 5 times she missed the board.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
She scores 52 positive points.
She gets a '- 3' score each time she misses the board.
And, Total final points = 37
Now,
Let the number of missed the boards = x
So, We can formulate as;
⇒ 52 - 3x = 37
Solve for x as;
⇒ 52 - 3x = 37
⇒ 52 - 37 = 3x
⇒ 15 = 3x
⇒ 3x = 15
⇒ x = 15/3
⇒ x = 5
Thus, There are 5 times she missed the board.

What are a) the ratio of the perimeters and b) the ratio of the area of the larger figure to the smaller figure?
A) 5/2 and 25/4
B) 5/2 and 7/4
C) 7/2 and 25/4
D) 7/2 and 7/4
Given:
Base of the larger figure = 30 yd
Base of the smaller figure = 12 yd
To find:
a) The ratio of the perimeters of the larger figure to the smaller figure.
b) the ratio of the area of the larger figure to the smaller figure.
Solution:
a) We know that, the ratio of perimeters pf similar figures is equal to the ratio of their sides.
The given figures are similar. So, the ratio of the perimeters is:
[tex]\text{Ratio of the perimeters}=\dfrac{\text{Base of the larger figure}}{\text{Base of the smaller figure}}[/tex]
[tex]\text{Ratio of the perimeters}=\dfrac{30}{12}[/tex]
[tex]\text{Ratio of the perimeters}=\dfrac{5}{2}[/tex]
b) The ratio of area of similar figures is equal to the ratio of squares of their sides.
[tex]\text{Ratio of the areas}=\dfrac{\text{Base of the larger figure}^2}{\text{Base of the smaller figure}^2}[/tex]
[tex]\text{Ratio of the areas}=\dfrac{(30)^2}{(12)^2}[/tex]
[tex]\text{Ratio of the areas}=\left(\dfrac{30}{12}\right)^2[/tex]
[tex]\text{Ratio of the areas}=\left(\dfrac{5}{2}\right)^2[/tex]
[tex]\text{Ratio of the areas}=\dfrac{25}{4}[/tex]
Therefore, the correct option is A.

What is a Scatter Plot?Dots are used in a scatter plot to show the values of two different numerical variables. Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.
The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from near the origin out to high y-values, the variables are said to have a positive correlation.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
Given data ,

If a triangle with the angles of 72 degrees, 62 degrees, and 46 degrees and one of the side lengths is 40, what would the length of the other two side be?
Answer:
The length of the other two sides are: 43.09 and 32.60
Step-by-step explanation:
Let the given side of the triangle be b(= 40), and the angles be;
A = [tex]72^{o}[/tex], B = [tex]62^{o}[/tex]and C = [tex]46^{o}[/tex].
Applying the Sine rule,
[tex]\frac{a}{SinA}[/tex] = [tex]\frac{b}{SinB}[/tex] = [tex]\frac{c}{Sin C}[/tex]
So that,
[tex]\frac{a}{SinA}[/tex] = [tex]\frac{b}{SinB}[/tex]
[tex]\frac{a}{Sin 72}[/tex] = [tex]\frac{40}{Sin62}[/tex]
a = [tex]\frac{0.9511*40}{0.8829}[/tex]
= 43.0898
a = 43.09
Also,
[tex]\frac{b}{SinB}[/tex] = [tex]\frac{c}{Sin C}[/tex]
[tex]\frac{40}{Sin62}[/tex] = [tex]\frac{c}{Sin46}[/tex]
c = [tex]\frac{0.7193*40}{0.8829}[/tex]
= 32.5881
c = 32.60
The length of the other two sides are: 43.09 and 32.60
