Xin recorded the grade-level and instrument of everyone in the middle school School of Rock below.
Answers
Answer:
13/35
Step-by-step explanation:
Probability determines the likelihood of an event happening.
Since we are not looking at the 7th Graders list, let's focus on the list on 8th Graders.
Given:
8th gradeGuitar - 4 students
Bass - 13 students
Drums - 13 students
Keyboard - 5 students
Since we are trying to find the probability of an eighth grader chosen at random to play the drums, let's turn our attention to how many students actually play the drums.
13 students play the drums.
In order to find the probability of a student chosen at random who plays the drums, we have to find how many students play the drums (which we already found) out of the total amount of students there are in that grade/section. Summing up, probability = the amount of favorable cases divided by the amount of possible cases.
Let's use this formula:
P(A) = n/N
Where "P(A)" stands for the probability of the event "A". And "n" represents the # of favorable outcomes and "N" represents the # of total possible outcomes.
Let's find how many students are in 8th grade now by adding all the people who play the musical instruments together:
4 + 13 + 13 + 5
= 35 possible outcomes.
Now let's plug it into the formula:
P(A) = n/N
P(A) = 13/35
13/35 can simplify any further.
The probability of choosing a student who plays the drums at random is 13/35.

Answers
Answer:
900. Give Braylist
Step-by-step explanation:
I'm right
80/360 = 200/x
where x is the total number of shoes sold. Solving for x, we get:
x = (360 * 200)/80
x = 900
Therefore, the total number of shoes sold is 900.

Interpreting the presidential election using the map descriptionFrom the question, we have the following parameters that can be used in our computation:
Description by county:
Land areas won by Republicans is greater than those won by Democrats.
Description by state:
Democrat winner = approximately half
Republican winner = approximately half
The above means that
The republican won the election
This is because;
When calculated by states, they have the same proportionWhen calculated by county, Republican hold more votesHence. The Republicans won the most electoral votes in the election.

Answer:
The answer is The Democrats won the most electoral votes in the election.
The map showing the results by county shows that the Republicans won more land area, but the map showing the results by state shows that the Democrats won more states. The electoral college is made up of electors from each state, and the number of electors each state has is equal to the number of seats it has in Congress plus its two senators. The Democrats won more states in 2008, so they won more electoral votes and the election.

Step-by-step explanation:
Earl made a 1/2 pan of brownies using 2/3 cup of sugar how much. sugar will it take for a whole pan of brownies
Answers
Let's call the amount of sugar needed for a whole pan of brownies "x". Since a whole pan is twice the size of a half pan, we can set up the proportion:
1/2 pan / 2/3 cup sugar = 1 whole pan / x cups sugar
To solve for x, we can cross-multiply and simplify:
1/2 pan * x cups sugar = 2/3 cup sugar * 1 whole pan
x/2 = 2/3
x = (2/3) * 2
x = 4/3
Therefore, Earl will need 4/3 cups of sugar for a whole pan of brownies. This can be simplified to 1 and 1/3 cups of sugar

4/3 Cups of Sugar

Answer:
105 square inches
Step-by-step explanation:
area of a triangle = 1/2( base * height)
The base is 5 and the height is 8.
= 1/2 ( 5 *8)
= 1/2(40)
= 20
The area of each triangle = 20 sq inches
So 4 triangles x 20 sq inches each = 80 sq inches.
The area of the square is 5 x 5 = 25 sq inches.
Add them together.
80 + 25 = 105 square inches

Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
3 of james's 5 panels produce 3/5E
4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
3/5E = 18/30E . . . . energy from James's panels
4/6E = 20/30E . . . energy from Ben's panels
18/30 < 20/30 . . . . so Ben's panels are producing more energy
