Answer:
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]P(Red) = \frac{2}{7}[/tex]
[tex]P(Blue) = \frac{3}{14}[/tex]
Required
Which completes the model
Let the remaining probability be x.
Such that:
[tex]P(Red) + P(Blue) + x = 1[/tex]
Make x the subject
[tex]x = 1 - P(Red) - P(Blue)[/tex]
So, we have:
[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]
Solve
[tex]x = \frac{14 - 4 - 3}{14}[/tex]
[tex]x = \frac{7}{14}[/tex]
[tex]x = \frac{1}{2}[/tex]
This mean that the remaining model must add up to 1/2
[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]
This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
Other options are also false

Answer:
a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.
b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.

Use the information to answer the following question.
The bottom of a swimming pool is 10 feet below the surface of the water in the pool. The surface of the water is represented by the number 0, and the bottom of the pool is represented by the number -10. The pool’s diving board is the same distance above the surface of the water as the bottom of the pool is below the surface of the water.
What number represents the location of the diving board?
A.
20
B.
0
C.
10
D.
1/10
Answer:
C
Step-by-step explanation:
Since the difference between 0 and -10 is 10, this means that the difference between the diving board and the pool also has to be 10. Therefore, the diving board is 10 feet above the water since 0+10 is 10.

Rewrite the following equation in slope-intercept form.
18x + 14y + 15 = 0
Answer:
y=-9/7x-15/14
Step-by-step explanation:
Slope-intercept form is y=mx+b
The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.
18x+14y+15=0
-15 -15
18x+14y=-15
-18x -18x
14y=-15-18x
14y=-18x-15
÷14 ÷14
y=-9/7x-15/14

Following PEMDAS, which is:
parentheses
exponents
multiplication
division
addition
subtraction
I found that the answer was 86
Answer:
-10.
Step-by-step explanation:
Step 1: Explain/define
This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.
P (Parenthesis)
E (Exponents)
M/D (Multiplication/division, whichever comes first)
A/S (Addition/subtraction, whichever comes first)
This is the correct sequence of steps when solving expressions with multiple operations.
PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."
------------------------------------------------------------
Step 2: Solve.
REMEMBER PEMDAS!
Expression given: 4 × 3 + 2 × 9 - 40
There are no parentheses.
There are no exponents.
There is multiplication, but no division.
4 × 3 + 2 × 9 - 40
12 + 18 - 40
There is addition and subtraction. Remember to solve whichever comes first.
12 + 18 - 40
30 - 40
30 - 40 = -10.
I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Classify this triangle.
A triangle with two sides of equal length. The angle where these two sides meet is ninety degrees.
A. Acute scalene triangle
B.Obtuse isosceles triangle
C. Right isosceles triangle
D Right scalene triangle
A triangle with two sides of equal length and the angle where these two sides meet is 90° is Right isosceles triangle. Therefore, option C is the correct answer.
What is a right triangle?A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.
A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.
Therefore, option C is the correct answer.

From the table, the ratio of white socks to brown socks is 9/8
Select two ratios equivalent to the ratio of white socks to brown socks.
A) 35/32 B) 40/46 C) 36/33 D) 45/40
Answer:
D
Step-by-step explanation:
To find an equivalent ratio it must be multiplied or divided by the same number.
I multiplied 8 by 5 which got me 40
Then I multiplied 9 by 5 which got me 45
This means the equivalent ratio is 45/40
There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?
Answer:
100
Step-by-step explanation:
First we get the ratio of 8:3 for the amount of boys to girls.
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 8 + 3 = 11
Part A = 8 and Part B = 3 are numerators for each fraction.
The fractions are then:
8/11 and 3/11
8/11 for boys
and 3/11 for the girls
Now we just multiply 220 by these fractions:
220 * 8/11 = 160
220 * 3/11 = 60
Then subtract:
160 - 60 = 100
Answer:
There are 60 girls and 160 boys
