1) What is the probability that a student prefers comedy, given that the student is in 10th grade?
2) What is the probability that a student prefers comedy, given that the student is in 12th grade?
3) What is the probability that a student does not prefer action, given that the student is in 9th grade?
Answers
Answer:
1/3
3/10
6/8 or 3/4
Step-by-step explanation:
The probabilities of the condition are 0.3333, 0.30, and 0.75.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Then the probability that a student prefers comedy, given that the student is in 10th grade, will be
Total event = 9
Favorable event = 3
Then the probability will be
P = 3 / 9
P = 0.3333
Then the probability that a student prefers comedy, given that the student is in 12th grade, will be
Total event = 10
Favorable event = 3
Then the probability will be
P = 3 / 10
P = 0.30
Then the probability that a student does not prefer action, given that the student is in 9th grade will be
Total event = 8
Favorable event = 6
Then the probability will be
P = 6 / 8
P = 0.75

Could you please show the work? I was able to get the area but can't exactly figure out what they want for the formula.
Compute the area under the graph as a limit.

Answers
Therefore , R(N) = 100 + 400 (N+1)(2N+1) + 800 x N2 N3 and area are the formulas for R(N) for the function f(x) = (5x)2 on [1, 5] and the function f(x) = (5x)2 in terms of N. R(N) = 767(approx) (approx).
What is function?Each x value in the domain has one but only one y value range, according to the rule of a function. Definition. If there is only one and only one value of x variable such that f(x) = y, then the function is one-to-one.
Here,
In the given question, we have to find a formula for R(N) for the function f(x) =(5x)^2 on [1, 5] in terms of N.
The given function is f(x)=(5x)^2 on [1, 5].
Ax = (5-1)/N
Ax = 4/N
X = 1+iAx
X = 1+i4/N
f(x) = 25X^2
f(x) = 25(1+i4/N)^2
f(x) = 25(1+i8/N+16/N^2 i^{2})
R(N) = 1ƒ(X) Ax
Now putting the value of f(x) and Ax
R(N)==1 [25 (1+ &i + 16i2)]
R(N) = 1001 (1 +Ni + 16i2)
N100 (1+i+12)N
100 (N += i +122)+16 N(N+1)(2N+1)(+1)(2N+1)
R(N)=100 (N + √2/ N(N+1) x 100
R(N) =2/6× N + 100 × 5 × N(N+1) + 100 x 2
[tex]\lim_{n \to \infty}[/tex] R(N) = 100 + 400 + 800/3
[tex]\lim_{n \to \infty}[/tex] R(N) = 766.67
[tex]\lim_{n \to \infty}[/tex] R(N) = 767(approx)
Therefore , the solution of the given problem of function comes out to be [tex]\lim_{n \to \infty}[/tex] R(N) = 767(approx).

The ratio of the measure of an exterior angle of a triangle to the measure of the adjacent interior angle is 1:4. Is the
triangle acute or obtuse?
Justify your answer.
A.) Acute; the measure of the interior angle must be 144º.
B.)Acute; the measure of the interior angle must be 36°.
C.)Obtuse; the measure of the interior angle must be 144º
D.)The triangle could be acute or obtuse, depending on the measures of the other two angles.
Answers
The ratio of the measure of an exterior angle of a triangle to the measure of the adjacent interior angle is 1:4, which means that for every 1 degree of the exterior angle, there are 4 degrees of the interior angle. However, this does not provide enough information to determine the overall shape of the triangle.
The triangle could be acute (all angles less than 90 degrees), right (one angle equal to 90 degrees), or obtuse (one angle greater than 90 degrees) depending on the measures of the other two angles. For example, if the interior angle measure is 36 degrees, the exterior angle would be 9 degrees, and the triangle could be acute. On the other hand, if the interior angle measure is 144 degrees, the exterior angle would be 36 degrees, and the triangle could be obtuse.

Mr Paul has 4 bars of chocolate. He distributes 1/3
of each bar to 4 children.
a) Write the fraction of chocolate distributed.
b) Write the fraction of cholates left with Mr. Paul
Answers
a) The fraction of chocolate distributed is given as follows: 4/3.
b) The fraction of chocolates left with Paul is given as follows: 8/3.
How to obtain the fractions?The fractions are obtained applying the proportions used in the context of this problem.
He distributes 1/3 of each bar to 4 children, hence the total number of bars distributed is given as follows:
4 x 1/3 = 4/3.
(multiplication of fractions, multiply the numerators and the denominators, keeping the quotient).
The total number of bars that Paul had initially is given as follows:
4 bars.
Then the fraction of chocolate remaining with Paul is given by the subtraction of the total amount of bars by the amount given to the children, as follows:
4 - 4/3 = 12/3 - 4/3 = 8/3 bars.
