Answer:

Step-by-step explanation:

a) At 6 beads for each inch, 9 inches will require 9×6 = 54 beads. The supply of beads will decrease by 54 beads when that number is used for a necklace. The change in supply is -54 beads.

b) 2 weeks is 14 days, so the average per day is ...

(42 mahi mahi)/(14 days) = 3 mahi mahi/day

olganol [36]

Answer:

100

Step-by-step explanation:

start with what's in the parenthesis':

8 (9.75 - 3.25) + 12 x 4 = 8 (6.50) + 12 x 4

then take the number outside of the parenthesis' time the number inside of them:

8 (6.50) + 12 x 4 = 52 + 12 x 4

now, take the product of the two number on the right side of the addition sign:

52 + 12 x 4 = 52 + 48

finally, add the final two numbers together:

52 + 48 = 100

Inside the box of every cereal box contains a surprise gift. The store manager assures employees that 22 of the 45 boxes on the

kherson [118]

Answer:

0.2333 = 23.33% probability that both of them have the secret decoder ring

Step-by-step explanation:

The cereals are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

45 boxes, which means that $N = 45$

22 have the secret decoder ring, which means that $k = 22$

Two boxes, which means that $n = 2$

What is the probability that both of them have the secret decoder ring?

This is P(X = 2). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,45,2,22) = \frac{C_{22,2}*C_{23,0}}{C_{45,2}} = 0.2333$

0.2333 = 23.33% probability that both of them have the secret decoder ring

What is the probability of rolling a three on the first die and a two on the second die?

Neporo4naja [7]

The two rolls of the number cube are independent events because
the result of 1 roll does not affect the result of the other roll.
To find the probability of two independent events, we first find
the probability of each event, then we multiply the probabilities.
We can find the probability of an event using the following ratio:
number of favorable outcomes/total number of outcomes
Since there is only one way to roll a 3 and there are six
possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.
Since there is also only one way to roll a 2 and there are
six possible outcomes, the probability of rolling a 2 would be 1/6.
Now we multiply the probabilities.
1/6 x 1/6 is 1/36.
So the probability of rolling a 3 and a 2 is 1/36.
