In a math class of 35 students, 17 boys and 18 are girls. On a unit test, 8 boys and 12 girls made an A grade. A student is chosen at random from the class. What is the probability of choosing a boy or an A student?
Group of answer choices

0.57

0.71

0.83

0.09

Answers

Answer 1

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)

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:

A quadrilateral A’B’C’D is reflected across the x-axis to form quadrilateral A’’B’’C’’D’’ then,

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

Answers

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.

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

Answers

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?

Answers

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

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.

Answers

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.

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

Answers

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
