The dimensions of the rectangle given are

length = 14 meters

Width = 8 meters

The perimeter of the rectangle is given by the sum of its sides

The rectangle has to opposite sides of 14 meters and two opposite sides of 8 meters

Hence adding up the 4 sides we get

8+14+8+14 = 44

Hence option B is the right answer

Naya [18.7K]

Answer:

0.0143

Step-by-step explanation:

In this question, we are asked to use the binomial distribution to calculate the probability that 10 or fewer passengers from a sample of MIT data project sample were on American airline flights.

We proceed as follows;

The probability that a passenger was an American flight is 15.5%= 15.55/100 = 0.155

Let’s call this probability p

The probability that he/she isn’t on the flight, let’s call this q

q =1 - p= 0.845

Sample size, n = 155

P(X < A) = P(Z < (A - mean)/standard deviation)

Mean = np

= 125 x 0.155

= 19.375

Standard deviation = √npq

= √ (125 x 0.155x 0.845)

= 4.0462

P(10 or fewer passengers were on American Airline flights) = P(X \leq 10)

= P(Z < (10.5 - 19.375)/4.0462)

= P(Z < -2.19)

= 0.0143

Find the measure of the indicator arc
harina [27]

Answer:

m(WXY) = 224°

Step-by-step explanation:

Measure of inscribed angle = ½ the measure of intercepted arc

Therefore:

m<C = ½*m(WXY)

112° = ½*m(WXY) (substitution)

Multiply both sides by 2

2*112° = m(WXY)

224° = m(WXY)

m(WXY) = 224°

A plumber charges an initial fee of $200 plus and hourly fee of $50. Mrs. Coombs paid the plumber $ 450. How many hours did the
nikitadnepr [17]

Answer:

5 hours

Step-by-step explanation:

The total cost is the fee plus the hours* hourly cost

450 = 200+50*h  where h is the hours

Subtract 200 from each side

450-200 = 200-200 +50h

250 = 50h

Divide each side by 50

250/50 = 50h/50

5 = h

5 hours
