Answer:
P(Blue) = 1/4
Step-by-step explanation:
hello
The first thing to see is the number of each color
There are 2 pinks(or reds)
There are 2
There are 2 yellow
And there are 2 blue
since all are two,
2 x 4
8 is the denominator
2 x 1
2 is the numerator
2/8 = 1/4
P(Blue) = 1/4
Answer:
Below!
Step-by-step explanation:
\(\text{Probability of getting blue on spinner:} \ \ \dfrac{\text{Total number of blue colors present in spinner}}{\text{Total number of colors present in spinner}}\)
⇒ Total colors: 4 + 4 = 8⇒ Total "blue" colors: 2Therefore, we get;
\(\text{Probability of getting blue on spinner:} \ \dfrac{\text{2}}8 = \boxed{\dfrac{1}{4}}\)
Therefore, the probability of getting a blue color is 1/4.

Blake had a job during his summer vacation. He earned $9.75 per hour and worked 30 hours a week for 8 weeks. How much money did Blake earn?
Answers
In order to get this answer, you simply multiply the amount of money earned each hour {9.75} and the amount of hours each week {30}. After doing so, you’ll need to multiply the amount earned {292.5} and the number of the weeks worked {8}. Hope this helps love, if it doesn’t make sense I’ll link a photo of the equation used too.

For number 5, the triangle sum theorem states that all angles inside of a triangle must add up to 180 degrees, so we have 30+90+66+x. Right angles are 90 degrees.
186+x=180
x=-6
For number 6, same rule applies here.
60+30x+90 = 180.
150+30x=180
x=1

Rational numbers

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

Answers
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

The volume of a pyramid can be found using the following formula:
\(\boxed{\large \textsf{$V=\frac{1}{3}Ah$}} \large \textsf{ where:}\\\\ \normalsize \textsf{$\bullet{\,V = $ volume of pyramid$}$}\\ \normalsize \textsf{$\bullet{\,A = $ base area$}$}\\ \normalsize \textsf{$\bullet{\,h = $ perpendicular height$}$}\)

Which of the following uses the distributive property correctly?
9(m – 2) = 9(m) – 9(2)
9(m – 2) = 9(m) – 2
9(m – 2) = 9 – 9(2)
9(m – 2) = 9(m) + 9(2)
Answers
You’re basically adding m - 2 nine times
So it’s 9m - 18
Or 9m - 9(2)
Answer:
9(m – 2) = 9(m) – 9(2)Step-by-step explanation:
The distributive property:

Answers
Answer:
x = 28
Step-by-step explanation:
1) Add 21 to both sides of the equation.
-4x - 21 + 21 = 91 + 21
2) Simplify
A. Add the numbers
-4x = 91 + 21
B. Add the numbers
-4x = 112
3) Divide both sides of the equation by the same term.
-4x/4 = 112/-4
4) Simplify
A. Cancel terms that are in both the numerator and denominator
x = 112/-4
B. Divide the numbers
x = 28
21
to both sides of the equation
−4 −21 = 91
−4 −21 + 21 =91+21
Then it will be = −28
