Answer:

(2, 24) (6, 72) (9, 108)

Step-by-step explanation:

For this one, we know that 2 chairs use 24 screws, which must mean that for each chair, 12 screws are needed, so we can just multiply 12 by the number of chairs being built (ex. 6) to find out how many screws are needed in total. I hope this helps :)

Answer:

a. 0.52 = 52% probability that Linda gives the correct answer to a question.

b. 0.7692 = 76.92% probability that Linda knows the answer

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Supplies the correct answer:

Event B: Knows the answer

A. What is the probability that Linda gives the correct answer to a question?

0.4(knows the answer)

1/5 = 0.2 of 1 - 0.4 = 0.6(guesses the answer). So

[tex]P(A) = 0.4 + 0.2*0.6 = 0.52[/tex]

0.52 = 52% probability that Linda gives the correct answer to a question.

B. What is the conditional probability that Linda knows the answer, given that she supplies the correct answer?

Intersection of events A and B is knowing the answer and giving the correct answer, which means that [tex]P(A \cap B) = 0.4[/tex]

The desired probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.4}{0.52} = 0.7692[/tex]

0.7692 = 76.92% probability that Linda knows the answer

Answer:

£140

Step-by-step explanation:

First count up the amount of full squares, then you see the partially filled squares and try find the match for it to fill the square. It ends up being 24 squares, meaning 24 square feet. That multiplied by £5, as that is the cost of red wood, gives you the answer of £140

Question 1:  70 mins

Question 2: R

Step-by-step explanation:

Answer:

286.5

Step-by-step explanation:

(3 x 7.5) x 2 = 45

(11.5 x 3) x 2 = 69

(11.5 x 7.5) x 2 = 172.5

45 + 69 + 172.5 = 286.5

Answer:

Step-by-step explanation:

Consider the angle of depression is same as the angle between horizontal line on the ground and the direct line from the plane to the airport (alternate interior angles).

Use tangent to find the missing length.

tan = opposite / adjacent

Answer:

We combine x ounces of 100% juice

with 40-x of 10% juice

to get 40 ounces of 55% juice

x + 0.1(40-x) = .55(40)

x + 4 - 0.1x = 22

0.9x + 4 = 22

.09x = 18

x = 20 ounces of 100% juice

40-x = 20 ounces of 10% juice

We combine 20 ounces of each.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

The answer is A

Step-by-step explanation:

Supplementary angles are angles which add up to 180°

∠1 and ∠3 add up to 180°, so they are supplementary.

Answer: 30 degrees

Step-by-step explanation:

The total is 180 degrees.

there is a right angle on the left. A right angle is 90 degrees.

180 - 90 = 90

There is still 90 degrees left, meaning that the right side is a total of 90 degrees.

2x + x = 3x

x = 90/3

x = 30

Therefore,

x = 30 degrees!

42

Step-by-step explanation:

Because of its shape I would imagine another flipped so it makes a square then solve for the square the divide.

7 x 12 =84

84÷2=42

Answer:

EG = 7

Step-by-step explanation:

The parallel lines cut sides AB and AC into segments with proportional lengths.

AB/DF = AC/EG

(AD + DF + FB)/DF = AC/EG

(18 + 10 + 12)/10 = 28/EG

40/10 = 28/EG

4 = 28/EG

4EG = 28

EG = 28/4

EG = 7

Answer:

A has 263 calories

B has 257 calories

Step-by-step explanation:

system of equations:

a + 2b = 777

2a + b = 783

I multiplied the first equation by -2 to eliminate the 'a' terms

  -2a - 4b = -1554

+ 2a  + b =    783

         -3b = -771

b = 257

solve for 'a'

a + 2(257) = 777

a + 514 = 777

a = 263
