Wendy's mother recorded how many donuts she has eaten over the past few months. Jelly-filled donuts 6 maple donuts 53 glazed donuts 11 powdered sugar donuts 5 What is the experimental probability that the next donut Wendy eats will be a powdered sugar donut? Write your answer as a fraction or whole number. P(powdered sugar donut) =
Answer:
[tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex] .
Step-by-step explanation:
It is given that Wendy's mother recorded how many donuts she has eaten over the past few months.
Jelly-filled donuts = 6
Maple donuts = 53
Glazed donuts = 11
Powdered sugar donuts = 5
Now,
Total number of donuts = 6 + 53 + 11 + 5 = 75
We need to find the experimental probability that the next donut Wendy eats will be a powdered sugar donut.
[tex]P(\text{Powdered sugar donut})=\dfrac{\text{Powdered sugar donuts}}{\text{Total number of donuts}}[/tex]
[tex]P(\text{Powdered sugar donut})=\dfrac{5}{75}[/tex]
[tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex]
Therefore, [tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex].
Find the length of AB
Hey there! :)
Answer:
arc AB = 2.5π in (in terms of pi) or ≈7.85 in. (pi = 3.14)
Step-by-step explanation:
Begin by finding the circumference of the circle. Use the formula:
C = 2rπ
C = 2(9)π
C = 18π.
Since ∠AQB equals 50°, set up a ratio to find the length of arc AB:
[tex]\frac{50}{360} = \frac{x}{18\pi }[/tex]
Cross multiply:
50 · 18π = 360x
900π = 360x
Divide both sides by 360:
x = 2.5π in, or ≈7.85 in.

The points (0, –1) and (4, 5) lie on the straight line L.
Find an equation of the line which is parallel to L and passes through the point (–2, 0).
Answer:
y = 3/2x + 3.
Step-by-step explanation:
With these two points, we can find the equation of line L.
y = mx + b
Slope: (5 --1) / (4 - 0) = 5 + 1 / 4 = 6 // 4 = 3/2
Intercept: [stated by the first pair of coordinates] (0, -1)
y = 3/2x - 1
Since the line is parallel to L, the slope is the same as line L.
y = 3/2x + b
The line passes through (-2, 0), so we can substitute the points into the equation and solve for b.
0 = 3/2 * -2 + b
b - 3 = 0
b = 3
So, the equation of the line which is parallel to L and passes through the point (-2, 0), is y = 3/2x + 3.
Hope this helps!

The graph for the equation y = negative 2 x + 1 is shown below. On a coordinate plane, a line with negative slope goes through (0, 1) and (1, negative 1). If another equation is graphed so that the system has no solution, which equation could that be?
Options:
y = negative 2 (x minus one-half)
y = negative one-half (4 x + 2)
y = negative x + 1
y = negative one-half x + 2
Answer:
y = negative 2 (x minus one-half)
Step-by-step explanation:
The equation of a line is given as:
y = mx + c, where m is the slope and c is the intercept on the y axis.
The equation of a line going through (0, 1) and (1, - 1) is calculated using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\ y-1=\frac{-1-1}{1-0}(x-0)\\ y-1=-2x\\y=-2x+1[/tex]
The solution of two lines is at their point of intersection. The equation of the line that would not have any solution with y = -2x + 1 would be a line that is parallel to y = -2x + 1. Since the two lines would be parallel to each other, their would be no intersection and therefore no solution.
Two lines are said to be parallel to each other if they have the same slope. The slope of y = -2x + 1 is gotten by comparing with y = mx + c, therefore the slope m = -2. From the options the only line with a slope m = -2 is y = -2(x -1/2). Therefore y = -2(x -1/2) is parallel to y = -2x + 1 and would have no solution

what number must you add to complete the square? x^2-7
Answer:
12.25
Step-by-step explanation:
To find the c value in the equation, we need to divide b by two and then square it.
b= -7 and -7/2 is 3.5
Then we square 3.5 and we get 12.25
Answer:
(x+0)^2-7
Step-by-step explanation:
x^2-7 to complete the square use the formula (b/2)^2 in order to create a new term.
ax^2+bx+c in this case b=0
(x+0)^2-7

A flare is fired from 4 feet above the ground at a speed of 64 feet per second. The flare will fall to the ground after it burns out.
Answer:
68 feet.Step-by-step explanation:
At maximum height, the velocity of the flare will be zero.
If the flare height above the ground is modeled by the equation
h = -16t²+64t+4
Velocity = dh/dt = 0
-32t + 64 = 0
-32t = -64
t = -64/-32
t = 2secs
This shows that the flare reaches its maximum height after 2secs.
To get the maximum height of the flare, we will substitute t = 2s into the equation h = -16t²+64t+4
h = -16(2)² + 64(2)+4
h = -64+128+4
h = 64+4
h = 68 feet
The maximum height of the flare is 64 feet.
If the point (8. 6) is the result of the composition T3,30 RO,-180º, what are the coordinates of the point prior to the
composition?
A. (-11, -9)
B. (-8, -3)
C. (-8,6)
D. (-5, -3)
Answer:
The correct answer is A. [tex](-11, -9)[/tex].
Step-by-step explanation:
Given that the point is (8,6)
Let this point be A(8,6).
The composition is T3,30 RO,-180º
First translate the point by 3,3.
Let this point becomes A'.
A' is formed by translation of point A by 3,3
i.e.
x coordinate of A' = x coordinate of A + 3 and
y coordinate of A' = y coordinate of A + 3
So, A' (8+3, 6+3)
So, A'(11,9)
Now, a rotation of -180º is applied to point A'.
Let it becomes A''.
By a rotation of -180º, the coordinate gets changed by 2 quadrants.
A is in 1st quadrant because both x and y coordinates are positive.
A'' will be in 3rd quadrant where both x and y coordinates are negative.
Please refer to the attached image for the graphical representation of A, A' and A''.
So, the answer will be option A. [tex](-11, -9)[/tex].
What is the slope of y= x+ 5
Answer: slope is 1
y- intercept =5
x-0,1
y- 5,6
Step-by-step explanation:
This equation is written in y = mx + b form where the m represents
the slope of the line and the b represents the y-intercept.
The equation y = x + 5 can be thought of as [tex]y = \frac{1x}{1} + 5[/tex].
So we can see that our slope is 1.

Answer:
6.1 square units
Step-by-step explanation:
Since the triangle was translated from one position to another position, the dimensions of the triangle have not changed. The pre-image and image are congruent.
area = base * height/2
The two sides forming a right angle can be used as the base and the height in the area formula.
BC = base = 2
AB = A'B' = height = 6.1
area = 2 * 6.1/2
area = 6.1 square units

2(3) + 125 = 131
216+131 = 347
Answer:
The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exercising. The function g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet, where x is the. number of hours spent exercising.

Answer:
2x^2 -x +1 = 0
Step-by-step explanation:
For roots α and β, the original equation can be factored as ...
f(x) = 2(x -α)(x -β)
If we add 1 to each of those roots, the factors become ...
g(x) = 2(x -(α+1))(x -(β+1))
This can be rearranged to be ...
g(x) = 2((x -1) -α)((x -1) -β)
That is, we can get the desired equation by replacing x with x-1, effectively shifting the function right one unit.
2(x -1)² +3(x -1) +2 = 0
2x^2 -x +1 = 0

Answer:
5 and 29
Step-by-step explanation:
If k= -2, l = 3, m = 4.
Then to solve
k + l + m and K^2 + l^2 + m^2 , we have to substitute the value of k, l and m with the respective values.
So for k + l + m :
k + l + m = -2 + 3 + 4 = -2 + 7 = 5
And for K^2 + l^2 + m^2:
K^2 + l^2 + m^2 = -2^2 + 3^2 + 4^2 = 4 + 9 + 16 = 29

MARK AS YK... Pweeeez
Answer:
B
Step-by-step explanation:
To solve this, we just need to keep in mind the following:
Vertical angles are always congruent.
Vertical angles are formed by a pair of intersecting lines. The angles across from each other are what we call vertical angles.
So, to find the congruent pair of angles, we just need to find a pair of vertical angles.
In the options given, the only option with a pair of vertical angles would be <13 and <15.
There are a few options that would be congruent if the line segments were parallel, but that is not a given.

Suppose that the distribution of lifetimes of females in France is not symmetric. According to Chebyshev's Theorem, at least approximately what percentage of these lifetimes are within k=3.8 standard deviations of the mean?
Answer:
93.7% of the lifetimes are within 3.8 standard deviations of the mean
Step-by-step explanation:
Generally Chebyshev's Theorem, can be mathematically represented as
[tex]1 - \frac{1}{k^2}[/tex]%
The percentage of these lifetimes that are within k=3.8 standard deviations of the mean is mathematically evaluated using Chebyshev's Theorem as follows
[tex]1 - \frac{1}{k^2}[/tex]% [tex]= (1 - \frac{1}{3.8^2} )[/tex]% = [tex]= 93.07[/tex]%
So from the above calculation we see that 93.7% of the lifetimes are within 3.8 standard deviations of the mean
