Answer:

The answer for the first question is attached with a picture!

For the second question, the answer is yes, more than half of the seats on the plane are being used.

Step-by-step explanation:

first class section has 14 Seats

Seat used = (5/7) * 14 = 10 Seats

Business class Section has 64 Seats

Seats used = (5/16) * 64 = 20 Seats

Economy class Section has 4 * 108 = 432 Seats

Seats used = (5/9) * 432 = 240 Seats

Total Seats = 14 + 64 + 432 = 510

Total Seats Used = 10 + 20 + 240 = 270

270/510 = 270 ( 2 * 255) > 1/2

the formula used to find the area of a triangle is A= 1/2bh, where is A of the triangle, b is the length of the base of the tria

aliya0001 [1]

If you are doing a literal equation all you have to do is isolate the h.
First get rid of the fraction by multiplying both sides by 2.
2a=bh
Then divide both sides by b.
2a/b=h
Hope this helps!

Approximately 9 out of every 50 people who saw a movie this week say they watched it on Netflix. Suppose we want to find the pro

uysha [10]

Answer:

1. As a fraction: 9/50

2. As a proportion: x/1 = 9/50

3. As a percentage: 18%

Explanation:

1. As a fraction:

Depart from the definition of probability: probability is the number of favoragle outcomes divided by the total number of possible outcomes:

Probability = number of movie-goers who say they watched a movie on Netflix this week / number of movie-goers that saw a movie this week

Probability = 9 / 50

2. As a proportion:

A proportion is the equality of two ratios. In this case you must set the ratio of people who say they watched it on Netflx, x, per every people who saw a movie this week, 1, equal to the ration 9 /50.

Hence, the proportion that shows the probability is:

x / 1 = 9 / 50

Where x is the probability.

3. As a percentage

You just have to multiply the probability by 100:

(9/50) × 100 = 18%

Algebra I Evaluate each function. h ( n ) = 2 n − 5 ; Find h ( 2 )

slavikrds [6]

Answer:

$h ( 2 ) = - 1$

Step-by-step explanation:

Two-Variable Functions

A function expresses the relation between two variables in such a way that for each input for the independent variable n, there one and only one value for the function h(n). If it's explicitly given as an equation, then we can use values for n as we wish, and compute the different values of h(n).

The question provides the following function

$h ( n ) = 2 n - 5$

We are required to find h(2), which can be computed by replacing n by the value of 2

$h ( 2 ) = 2 (2) - 5$

$h ( 2 ) = 4 - 5$

$h ( 2 ) = - 1$
