Part A

kkurt [141]

Answer:

Part A: A

Part B: A

Step-by-step explanation:

the inequality should be less than or equal to, since we need to find how many are left

now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few

thus, the answer is A

A again is correct, since it represents:c ≤ 56

B represents c ≥ 56

C represents c ≤ –56

D represents c ≥ -56

aleksklad [387]

Answer:

12 more people adopted a manatee this year.

Step-by-step explanation:

Convert 30% into a decimal. Divide the percentage by 100:

30 / 100 = 0.3

The problem can be solved with the following equation:

0.3(40) = difference

Multiply 0.3 by 40.

0.3 * 40 = 12

12 more people adopted a manatee this year.

A family has five children. Assuming that the probability of a girl on each birth was 0.5 and that the five births were independ

kipiarov [429]

Answer:

The probability that the family has at least one girl, given that they have at least one boy 0.80.

Step-by-step explanation:

Construct the sample space for all the 5 children as follows:

S = {GGGGG, GGGGB, GGGBB, GGBBB, GBBBB and BBBBB}

There are a total of 6 outcomes.

First compute the probability of at least 1 boy.

Favorable outcomes : {GGGGB, GGGBB, GGBBB, GBBBB and BBBBB} = 5

Then the probability of at least 1 boy is,

$P(At\ least\ 1\ boy)=\frac{5}{6}$

Of these 5 samples the sample space for at least 1 girl is:

{GGGGB, GGGBB, GGBBB and GBBBB} = 4

Then the probability of at least 1 girl given at least 1 boy is,

$P(At\ least\ 1\ girl|At\ least\ 1\ boy)=\frac{4}{5}=0.80$

Thus, the probability of at least 1 girl given at least 1 boy is, 0.80.
