there are 6 boys and 5 girls in the debate class. kids are being selected to go present their work without getting opt-out where is the probability that a boy will be selected to present twice?
Answer:
30%?
Step-by-step explanation:
6 boys, 5 girls
first selection is a 6/11 chance it's a boy.
second seletion is a 6/11 chance it's a boy.
6/11 times 6/11 is... 0.2975 or about a 30% chance ( i think)
Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.
1. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
What is the sample space for Janessa’s calculation?
A. [3, 4]
B. [1, 2, 5, 6]
C. [1, 2, 3, 4, 5, 6]
D. [5, 6]
2. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
A. Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.
B. Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
C. Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.
D. Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
3. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
How many desired outcomes should Janessa use in her probability calculation?
A. 2
B. 3
C. 4
D. 6
A bag contains 8 red pens, 7 blue pens, and 14 black pens. Denato will pull a pen from the bag.
4. When Denato pulls a pen from the bag, how many outcomes are possible?
A. 29
B. 7
C. 8
D. 14
Answer:
I know for number 2 its- D. Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
Step-by-step explanation:
ill edit to find the rest of the answers
a) The sample space for Janessa's calculation is [ 5 , 6 ]
b) Her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c) The number of desired outcomes for Janessa's probability is 2.
d) There are 29 possible outcomes
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Since Janessa needs to roll a number higher than both her friends to win the game, the possible outcomes for her roll are limited to 5 and 6, since these are the only numbers that are higher than 4 and 3. Therefore, the sample space for Janessa's calculation consists of the numbers 5 and 6, which can be written as [5, 6]
b)
The probability of Janessa winning is a dependent event because it depends on the results of her friends' rolls. If one of her friends had rolled a higher number, then the probability of Janessa winning would be 0. Therefore, the outcome of Janessa winning is dependent on the outcomes of her friends' rolls.
Hence , her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c)
Janessa needs to roll a number higher than both friends, and the only numbers that meet this criteria are 5 and 6. Therefore, the number of desired outcomes for Janessa's probability calculation is 2.
d)
There are a total of 8 + 7 + 14 = 29 pens in the bag. When Denato pulls a pen from the bag, there are 29 possible outcomes since he can choose any of the 29 pens in the bag.
Hence , the probabilities are solved

Answer:
10x+40
Step-by-step explanation:
To solve you must follow these steps:
1. Multiply the outside (5) by the first number on the inside (2x) and you get 10x
2. Multiply the outside (5) by the second number on the inside of the parenthesis (8) and you get 40
3. You are left with 10x and 40, so your answer is 10x+40

Find the value of x and m∠HKL.
Answer:
x = 25 degrees ∠HKL = 102 degrees
Step-by-step explanation:
The whole thing equals 180, since it is a straight angle
The value of HKL is 180 - 78 = 102
So that means 4x + 2 = 102
Subtract 2 from both sides:
4x = 100
Divide both sides by 4:
x = 25

If you bought 24 light bulbs, how much money would you save by buying the less expensive light bulbs?
with the more expensive light bulbs, the cost would be $155.52
with the less expensive light bulb, the cost would be $119.04
This means you would save $36.48
Answer:
$3.84 is the amount you save by purchasing the cheaper lightbulbs when buying 24.
Step-by-step explanation:
Alrighty, so!
With this one, I broke down the price per lightbulb (divided the money by the amount of bulbs in the package).
$4.96/4= $1.24/bulb
$6.48/6= $1.08/bulb
I then multiplied that amount per bulb by 24.....
$1.24 x 24 = $29.76
$1.08 x 24 = $25.92
.... And subtracted the lower number from the higher number to get the answer.
$29.76-$25.92= $3.84
Hope this helps :D

Is a triangle with leg lengths of 9 in. and 9 in. and hypotenuse of length √175 in. a right triangle?
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
√162 = c
If it was a right triangle, its hypotenuse would be √162 inches long.

Step-by-step explanation:
It is a right triangle, so it can be solved with the Pythagorean Theorem.
Answer:
Step-by-step explanation:
Length of PR = 40 units
Length of RQ = 70 units
ΔPQR is a right angle. So, to fin the length of PQ, use Pythagorean theorem
hypotenuse² = base² + altitude²
PQ² = PR² + RQ²
= 40² + 70²
= 1600 + 4900
= 6500
PQ = √6500 = 80.62 units
PQ = 80.62 units
