The probability that the selected student is a sophomore given that he is a boy will be 5/12.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
we need to select the probability that the selected student is a sophomore given that he is a boy;
In this case;
P(B) = P(boy)
P(A) = P(sophomore)
The total number of students which is 12 + 18 = 30
From the table;
P(B) = 12/30
P(A n B) = 5/30
So;
P(A|B) = 5/30 / 12/30
= 5/30 x 30/12 = 5/12
Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.

Answer:
x=27
∠JLK=2x+1=2(27)+1=55
Step-by-step explanation:
∠A+∠K=180
3x+13+∠K=180
∠K=167-3x
∠K+∠L+∠J=180
167-3x+39+2x+1=180
207-x=180
x=27
∠JLK=2x+1=2(27)+1=55
Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.
Answer:
x = 27°∠JLK = 55°Step-by-step explanation:
∠AKL is exterior angle and as per property it is equal to sum of two non-adjacent angles:
∠AKL = ∠ KJL + ∠JLK3x + 13° = 39° + 2x + 1°Solving for x
3x - 2x = 39° + 1 - 13x = 27°And finding the value of ∠JLK:
∠JLK = 2x + 1 = 2*27° + 1° = 55°drop the craziest thing you have ever done the best answer gets to be the top brainliest let it begin plus u gt 50
Okay so not super crazy but one night me, my brothers, my cousin, and a few friends from our campground stayed up all night and walked in the rain. Not the crazy part though obviously. It was pouring and we got to the complete opposite side of the camp and through the woods and thought it was a good idea to go to the 'abandoned bathrooms" at like 2 in the morning. So we walked through the woods and made it there, we then found that someone boarded it up so you couldn't enter the bathrooms anymore. My older brother found a crowbar on the ground and beat the hecc out of the boys side boards until we could go in. We went in and messed around for a bit. We didn't make it home until the early hours of the morning. It was really fun and we got to scare my cousin lol

Solve the equation using inverse operations. Check your solutions. In you final answer, include all of your work.
Answer:
x = ±6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra II
Extraneous solutions and multiple answers/rootsStep-by-step explanation:
Step 1: Define
-x² = -36
Step 2: Solve for x
Divide -1 on both sides: x² = 36Square root both sides: x = ±6Step 3: Check
Plug in x to verify it's a solution.
Substitute in -6: -(-6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Substitute in 6: -(6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Here we see that both -6 and 6 do indeed work as solutions.
∴ x = ±6 are both solutions to the equation.

N=480×10^9
Write N as a product of powers of its prime factors.
Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

- 7x ≥ 21 Add 13 on both sides
Step 3:
x ≥ 21 ÷ - 7 Divide
Answer:
x ≥ - 3
Hope This Helps :)
Answer: x≤−3
Step-by-step explanation:
So first you -7*x-13-(8)≥0
then you are supposed to pull out like the factors -7x - 21 = -7 • (x + 3)
then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got x ≤ -3 So I really hoped this helped :)

Answer:
The correct option is;
0.01 and (1 × 1/100)
Step-by-step explanation:
The given parameters includes;
The batting average of Yordan Alvarez's = 0.317
Therefore, we have;
The digit in the hundredths place = 0.01
The expanded notation for the value of the hundredth place is given by the product of the digit and the place value digit as follows;
The expanded notation = 1 × 1/100.

jellybeans. Find the percent of error. Round to the nearest hundredth of a
percent if necessary.
HELP IM IN A QUIZZZ
Answer: 14%
Step-by-step explanation:
From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:
= Difference in error / Actual value × 100
= (107 - 92) / 107 × 100
= 15/107 × 100
= 0.14 × 100
= 14%
