Answer:
.83
Step-by-step explanation:
In order to find the probability that either a boy or an A student is chosen, you must first identify how many boys and A students there are altogether in the class:
9 boys who are not A students + 8 boys who are A students + 12 girls who are A students = 29 students are either boys or A students
Now, you just need to turn this into a probability:
1: 29/35 (given)
2: ≈82.86/100 (multiply both the numerator and denominator by 100/35)
3: ≈83% or .83 (round to the ones place and turn into a decimal)

Part B:
Then quadrilateral A’B’C’D is reflected across the x-axis to form quadrilateral A’’B’’C’’D’’. What are the signs of the coordinates (x,y) of point B’’?
Part A: The signs of the coordinates (x,y) of point C' option A: (-4,4).
Part B: The signs of the coordinates (x,y) of point B’' are (3,6).
What is a quadrilateral?A quadrilateral is a polygon having four sides, four angles, and four vertices.
Part A:
In this case, because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
The signs of the coordinates (x,y) of point C' option A: (-4,4).
Part B:

The graph of y=f(x) is shown below. Find all values of x where f(x)=-8
Answer:
4
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
-8 is the value of the y-coordinate, so you must find the x-coordinate that will match with that value. As you move horizontally to the right at y = -8, you will see that x = 8 is met.

The general form of equation of a line is
A. ax - by = c
B. a(x - y) + c = 0
C. ax + by + c = 0
D. a + b(x + y) - c = 0
Answer:
C. ax + by + c = 0
Step-by-step explanation:
The formula 0 = Ax + By + C is said to be the 'general form' for the equation of a line. A, B, and C are three real numbers. Once these are given, the values for x and y that make the statement true express a set, or locus, of (x, y) points which form a certain line.
What’s the answer to the missing angle?
Answer:
a = 159
Step-by-step explanation:
180 - 21 = a
a = 159
Answer:
159°
Step-by-step explanation:
Both the angles add up to 180° since they lie along a straight line.
So do 180 - 21 to get the measure of angle a.
a = 159°

The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle
Answer:
135
Step-by-step explanation:
The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle
Two Angles are Supplementary when they add up to 180 degrees.
Two Angles are Complementary when they add up to 90 degrees
Let the angle = x
Supplement of the angle = y
The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle
x - 180 = 3(x - 90)
x - 180 = 3x - 270
Collect like terms
3x - x = 270 - 180
2x = 90
x = 90/2
x = 45
x+ y = 180
45 + y = 180
y = 180 -45
y = 135
Factor the trinomial. p2 - 4p - 5
What is the a, b and c?
Answer:
(p - 5)(p + 1)
Step-by-step explanation:
Given
p² - 4p - 5
Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)
The factors are - 5 and + 1 , since
- 5 × + 1 = - 5 and - 5 + 1 = - 4, then
p² - 4p - 5 = (p - 5)(p + 1) ← in factored form
The standard form of a trinomial is
ax² + bx + c ( a ≠ 0 )
p² - 4p - 5 ← is in standard form
with a = 1, b = - 4 and c = - 5

Answer:
Area of rectangle = 54
Area of triangle= 18
Total area = 72
Step-by-step explanation:
Area of rectangle = length × width
= 9 × 6
= 54
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
[ Height of the triangle = 10 - 6 = 4 ]
Area of a triangle = [tex]\frac{1}{2}[/tex] × 9 × 4
= 18
Total area = Area of rectangle + Area of triangle
= 54 + 18
= 72
[ The unit should be: [tex]cm^{2}[/tex] or [tex]m^{2}[/tex] etc.; it should have the 'square'. ]
Ada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice. Let s represent the number of cups of sparkling water and j represent the number of cups of apple juice. Write an equation that shows how and are related.
Answer:
s = 2j
Step-by-step explanation:
Given - Ada makes sparkling juice by mixing 2 cups of sparkling water
with every 4 cups of apple juice. Let s represent the number of
cups of sparkling water and j represent the number of cups of
apple juice.
To find - Write an equation that shows how s and j are related.
Proof -
Let total number of cups of sparkling water make = s
Total number of cups of apple juice make = j
Now,
Given that, Ada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice.
⇒2s = 4j
⇒s = 2j
∴ we get
Ada can makes sparking water by mixing 2j cups of sparking water with every j cups of apple juice.
Use the data to answer the following question.
Consider the mean, median, mode, and range of each data set. Which is NOT the same for both sets of data?
A.
mode
B.
range
C.
median
D.
mean
Answer: a
Step-by-step explanation:
Version A:
Mean = 20
Median = 20
Mode = 10 and 30
Range = 20
Version B:
Mean = 20
Median = 20
Mode = 20
Range = 20
What is median?It is the middles value of the given set of numbers after arranging the given set of numbers in order.
We have,
Version A:
Mean:
It is the average value.
= (5 x 10 + 3 x 15 + 20 + 3 x 25 + 5 x 30) / 17
= (50 + 45 + 20 + 75 + 150) / 17
= 20
Median:
It is the mid-value.
10, 10, 10, 10, 10, 15, 15, 15, 20, 25, 25, 25, 30, 30, 30, 30, 30
= 20
Mode:
The number that occurs most times.
= 10 and 30
Range:
Highest value - Lowest value.
= 30 - 10
= 20
Version B:
Mean:
= (10 + 3 x 15 + 5 x 20 + 3 x 25 + 30) / 13
= (10 + 45 + 100 + 75 + 30) / 13
= 20
Median:
The number that occurs most times.
10, 15, 15, 15, 20, 20, 20, 20, 20, 25, 25, 25, 30
= 20
Mode:
= 20
Range:
= 30 - 10
= 20
Thus,
Version A:
Mean = 20
Median = 20
Mode = 10 and 30
Range = 20
Version B:
Mean = 20
Median = 20
Mode = 20
Range = 20
