So for 32 it’s Pi*squared. So Pi*8^2. If ur rounding to no decimal places. Then it will be 201. So 32 is c)201
Answer:

Question:
The probability of a certain brand of battery going dead within 15 hours is 1/3. Noah has a toy that requires 4 of these batteries. He wants to estimate the probability that at least one battery will die before 15 hours are up.1.Noah will simulate the situation by putting marbles in a bag. Drawing one marble from the bag will represent the outcome of one of the batteries in the toy after 15 hours. Red marbles represent a battery that dies before 15 hours are up, and green marbles represent a battery that lasts longer.How many marbles of each color should he put in the bag? Explain your reasoning.
Answer:
The number of marbles of each color that should be present in the bag is;
1 red marble and 2 green marbles
Step-by-step explanation:
Here, we note that the probability of a battery going dead = 1/3 and the
Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag
That is there should be 1 red marble and 2 green marble in the bag.
B) 6 ounces
not 100% sure though
Answer:
y = 3/5x + 5
Step-by-step explanation:
Gradient of the line
y = 3/5x + c
Substitute either point in to find c
y = 3/5x + c at (0,5)
5 = 3/5(0) + c
5 = 0 + c
5 = c
y = 3/5x + c at (-5,2)
2 = 3/5(-5) + c
2 = -3 + c
2 + 3 = c
5 = c
y = 3/5x + c
Replace c with 5
y = 3/5x + 5
