Answer:
[tex]P(Not\ Blue) = \frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]Red = 6[/tex]
[tex]Blue =5[/tex]
[tex]Green = 4[/tex]
Required
The probability of not selecting blue.
This means that any of the other colors is selected.
So, we have:
[tex]P(Not\ Blue) = P(Red) + P(Green)[/tex]
[tex]P(Not\ Blue) = \frac{Red}{Total} + \frac{Green}{Total}[/tex]
[tex]P(Not\ Blue) = \frac{6}{15} + \frac{4}{15}[/tex]
Take LCM
[tex]P(Not\ Blue) = \frac{6+4}{15}[/tex]
[tex]P(Not\ Blue) = \frac{10}{15}[/tex]
Divide by 5/5
[tex]P(Not\ Blue) = \frac{2}{3}[/tex]

Write the property that matches the equation.
3+(4+7)=(3+4)+7
Answer:
associative property
Step-by-step explanation:
Answer:
Associative property of addition
Step-by-step explanation:
The associative property states that numbers can be added or multiplied regardless of their paratheses. This means that how the numbers are grouped can change and still be equal. Another example of this would be [tex]2+(6+5)=(2+6)+5[/tex]. In both equations the sides are balanced.

Don’t put links !
Answer:
Because they are supplementary angles, their sum is 180°.
∠b = 180° - 81°
∠b = 99°
Answer:
[tex]180-81=b[/tex]
Step-by-step explanation:
Supplementary angles are angles that add up to 180. Normally, they are supplementary because they lie adjacent to one another on a line.
In this base, b is supplementary to 81! Meaning, to find b we can simply subtract 81 from 180.

Four members of a relay team evenly split the distance of a race. Each person ran more than 100 meters. Which inequality can be used to represent d, the total distance the group ran?
4 d greater-than 100
4 d less-than 100
StartFraction d Over 4 EndFraction greater-than 100
StartFraction d Over 4 less-than 100
Answer:
The answer would be C.
Step-by-step explanation:
Since each person ran more than 100 meters, the answer would be greater than 100.
d is the total distance the group ran, not the individual distance, so it couldn't be 4d because that would mean it would be 4 times d.
The answer would be d divided by 4. d/4. That is because the total distance divided by 4 would be the individual distance.

it is c

On Monday, 248 students went on a trip to the zoo. All 6 buses were filled and 8 students had to travel in cars. How many students were in each bus?
Answer:
40 students in each bus.
Step-by-step explanation:
Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.
248-8=240
240/6=40
40 students in each bus.
In some 4.0 grading systems, a student's grade point average (GPA) is calculated by assigning letter grades the following numerical values.
A = 4.00 B− = 2.67 D+ = 1.33
A− = 3.67 C+ = 2.33 D = 1.00
B+ = 3.33 C = 2.00 D− = 0.67
B = 3.00 C− = 1.67 F = 0.00
Use this grading system to find this student's GPA. Round to the nearest hundredth.

On the first two downs, a football team lost 15 yards and then lost 19 yards. Write an expression with addition that shows the changes in yards on the first two downs.
Answer:
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34
Step-by-step explanation:
At the first down, the net yardage of the football team was of 0.
After the first play:
Lost 15 yards, so the change in yards is:
0 - 15 = -15
After the second play:
Lost 19 yards, so the change in yards is:
-15 - 19 = -(15 + 19) = -34
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34

Step-by-step explanation:
Interquartile range (IQR) = Q3 - Q1
From the box plot given, the third quartile (Q3) is the data value that falls exactly at the end of the edge of the rectangular box = 7 cm
The first quartile (Q1) is the data value exactly at the beginning of the edge of the box = 5.5 cm

A point is chosen at random on AK what is the probability that the point will be on FI don't reduce
Answer: 3/10
Step-by-step explanation:
The probability that the point will be on FI is 3/10 if a point is chosen at random on AK the answer is 3/10.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have a number line shown in the picture:
Total Number partition or gaps between each letter(between A and K):
= 10
Total number of outcomes = 10
Total number of favorable outcomes(between F and I) = 3
The probability that the point will be on FI:
By using the definition of the probability:
= favorable outcomes/total outcomes
= 3/10
Thus, the probability that the point will be on FI is 3/10 if a point is chosen at random on AK the answer is 3/10.

A textbook store sold a combined total of 354 history and sociology test books in a week. The number of history textbooks sold was two times the number of sociology textbooks sold. How many textbooks of each those were sold?
Answer: History textbooks sold = 236, Sociology textbooks sold = 118
Step-by-step explanation:
Given
- There are in total 354 books
- Let x be the number of sociology textbooks sold
- Let 2x be the number of history textbooks sold
Solve
Given
x + 2x = 354
Combine like terms
3x = 354
Divide 3 on both sides
3x / 3 = 354 / 3
x = 118
2x = 118 × 2 = 236
Hope this helps!! :)
Please let me know if you have any questions
Answer:
sociology textbooks = 118history textbooks = 236Explanation:
sociology textbooks = 2 × history textbooks
354/3 = 118
sociology textbooks = 118
history textbooks = 118×2 = 236

What is the area of the triangle?
Answer:
11 ½ * 4* 5.52 *5.5=11.....….could someone possibly help me ??
Answer:
b
Step-by-step explanation:
The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the lengths of the three sides of the triangle. Enter an exact answer. Do not type your answers as fractions or decimals.
a^2 + b^2 = c^2
Let c = hypotenuse = 2x
One of the legs = x. Let a or b = x.
I will let a = x. We can then say that b = 3.
3^2 + x^2 = (2x)^2
9 + x^2 = 4x^2
9 = 4x^2 - x^2
9 = 2x^2
9/2 = x^2
sqrt{9/2} = sqrt{x^2}
3/sqrt{2} = x
Rational denominator.
[3•sqrt{2}]/2 = x = a
Side 3 is given to be 3 feet. So, b = 3.
Hypotenuse = 2x
Hypotenuse = 2([3•sqrt{2}]/2)
Hypotenuse = 3•sqrt{2}
Understand?
The three sides are 3, [3•sqrt{2}]/2 and
3•sqrt{2}.

Answer:
First box: -5, 0, 6, 9
Second box: 10, 12.5
Step-by-step explanation:
4x-12≤24
4x≤24+12
4x≤36
x≤36÷4
x≤9
So the first box would have all the solutions less than or equal to 9:
-5, 0, 6, 9
And the second box would have the solutions greater than 9:
10, 12.5
