Dima020 [189]
First problem
The recipe is written for 3 dozen cookies.
Hew wants to make 12 dozen cookies.
12 dozen is 4 times 3 dozen, so multiply each amount by 4 to make 12 dozen cookies.

4 eggs * 4 = 16 eggs
1/2 cup chocolate chips * 4 = 2 cups chocolate chips

Second problem
Let's start from the end.

There were 40 apples left on the tree.
Sally picked 1/3 of the apples that were left for her.
40 apples were left after Sally finished.
Since Sally picked 1/3 of the apples, she left 2/3 of the apples on the tree.
2/3 of the apples were 40 apples. 1/3 is 20 apples, so the number of apples left for Sally is 60 apples. Before Sally started, there were 60 apples.

Bill had picked 1/2 the apples, which means he left half of them. He left 60. That means to original number was 120 apples.

Answer: 120 apples.

An automobile manufacturer is concerned about a possible recall of its best selling four-door sedan. If there was a recall there
goldfiish [28.3K]

Complete question is;

An automobile manufacturer is concerned about a possible recall of its best - selling four-door sedan. If there were a recall, there is a probability of 0.25 of a defect in the brake system, 0.18 of a defect in the transmission, 0.17 of a defect in the fuel system, and 0.40 of a defect in some other area.

(a) What is the probability that the defect is the brakes or the fueling system if the probability of defects in both systems simultaneously is 0.15?

(b) What is the probability that there are no defects in either the brakes or the fueling system?

Answer:

A) 0.27

B) 0.73

Step-by-step explanation:

Let B denote that there is a defect in the break system

Let T demote that there is a defect in transmission

Let F denote that there is a defect in the fuel system.

Let P denote that there is a defect in some other area.

Now, we are given;

P(B) = 0.25

P(T) = 0.18

P(F) = 0.17

P(O) = 0.40

A) We are given that probability of defects in both brakes and the fueling system simultaneously is 0.15.

Thus, it means; P(B ⋂ F) = 0.15

Now, we want to find the probability that the defect is the brakes or the fueling system. This is expressed as;

P(B ⋃ F) = P(B) + P(F) - P(B ⋂ F)

Plugging in the relevant values to give;

P(B ⋃ F) = 0.25 + 0.17 - 0.15

P(B ⋃ F) = 0.27

B) We want to find the probability that there are no defects in either the brakes or the fueling system.

This is expressed as;

P(B' ⋃ F') = 1 - P(B ⋃ F)

Plugging in relevant value;

P(B' ⋃ F') = 1 - 0.27

P(B' ⋃ F') = 0.73

2t-7-5t=11 what is the answer
Verizon [17]
<span>2t-7-5t=11

Start by combing like terms:

2-5t=-3t  

Now we have: 

-3t-7=11  

Add 7 to both sides

-3t=18

To isolate t we divide both sides by -3 

Final answer: 
t=-6 </span>
