It is given that:

The percent of change 62 trees to 31 trees

Let x be the percent:

The value of x can be evaluated as:

As we know, the usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

x = [(62 - 31)/62]×100

Answer 2

Answer: To find the percentage of change, find the difference between the two by subtracting 31 from 62, leaving you with 31. Divide 31 by 62, which should give you 0.5. Multiply this number by 100, leaving you with 50%. There is a 50% change from 62 trees to 31 trees.

An airplane flight has 228 seats. The probability that a person who buys a ticket actually goes on that flight is about 95%. If the airline wants to fill all the seats on the flight, how many tickets should it sell?A. Show your work.

B. Should your answer be more than 228 or less? Explain.

Answers

there should be 240 tickets sold

I made a proportion by doing 228/95 and equaling it to x/100

x= the number of seats that needs to be sold

I crossed multiplied
and got
95x=228×100

228×100=22800

95x=22800

then I diveded both sides by 95 and got

x=240

hope this helps :)

Final answer:

The airline should sell 217 tickets to have a 95% probability that all seats will be filled.

Explanation:

To determine how many tickets the airline should sell, we need to find the number of tickets that corresponds to a 95% probability of a person actually going on the flight. We can think of this as finding the number of tickets that gives us a 95% confidence level.

We can use the formula for confidence interval to find the number of tickets:

Number of tickets = (Desired confidence level) × (Total number of seats)

Number of tickets = 0.95 × 228 = 216.6

Since we can't sell a fraction of a ticket, the airline should sell 217 tickets to have a 95% probability that all seats will be filled.

Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?

Answers

Answer:

Any equation of the line that is different from y=x is the solution to the problem.

Step-by-step explanation:

step 1

Find the slope of the line that passes through the points (1, 1) and (5, 5)

m=(5-1)/(5-1)=1

step 2

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have m=1

(x1,y1)=(1,1)

substitute

y-1=(1)(x-1)

y=x-1+1

y=x

therefore

Any equation of the line that is different from y=x is the solution to the problem.

What is 4 3\4 as a fraction?

Answers

4 3/4 is a mixed number (a whole number and a fraction), to find out its value in fraction form, we have to convert the number '4' into a fraction.

4= x/4

The number 4 is equal to 16/4

4= 16/4

Now we can solve the problem

4 3/4=
4+3/4=
16/4+3/4=19/4

4 3/4 as a fraction would be 19/4

To turn a mixed number into a improper fraction, we multiply 4 by 4 and add 3. In this case, we have a mixed number of 4 3/4, 4*4=16, 16+3=19. Therefore, 4 3/4 as a improper fraction is 19/4.

What is the probability of selecting a red card from a standard deck of 52 playing cardships that does not contain a joker?

Answers

We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) = $(26)/(52)$
= $(1)/(2)$

Probability ( selecting red card ) = $(1)/(2)$ Answer

1/2. half of the cards(26 out of 52) are red. you can reduce 26/52 to 1/2.
