JulsSmile [24]

Answer:

f(x) = 26000000(.85)^x + 2,000,000

f(1) = 26,000,000

f(2) = 24100000

f(3) = 22485000

f(4) = 21112250

Geometric, it is going down by a %, not a fixed number

Year 5, less pollution

f(8) = 9,084,753.65

Step-by-step explanation:

f(2) = 26,000,000 (.85)^2 + 2,000,000

f(2) = 24100000

f(3) = 26,000,000 (.85)^3 + 2,000,000

f(3) = 22485000

f(4) = 26,000,000(.85)^4 + 2,000,000

f(4) = 21,112,250

f(8) = 26,000,000(.85)^8 + 2,000,000

f(8) = 9,084,753.65

Suppose that the probability that a person books a hotel using an online travel website is 0.68. For the questions that follow,

Lorico [155]

Answer:

0.213 is the required probability.

Step-by-step explanation:

We are given the following information:

We treat person booking from online travel website as a success.

P(Booking through online travel website) = 0.68

Then the number of people follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 15

P(exactly ten people out of fifteen people used an online travel website)

$P(x = 10)\\\\= \binom{15}{10}(0.68)^{10}(1-0.68)^5 \\\\= 0.213$

0.213 is the probability that exactly ten people out of fifteen people used an online travel website when they booked their hotel.

In basketball, some baskets are worth two points. Others are worth three points. In one game, the ratio of three-point basket

Alex787 [66]

The number of three-point tries is 36.

<h3>What are ratios?</h3>

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

<h3 /><h3>What is the number of three point tries?</h3>

The first step is to determine the total number of tries and baskets: (27 X 7)/3 = 63

Number of three-point tries = (4/7) x 63 = 36

the number of words x tina can type per minute is at least 50. write and graph an inequality to describe this situation

marshall27 [118]

I can only write a inequality here but here goes...
since she can atleast type 50 per minute that means the equation would be x >50 (you would also put the line under the > because it can equal it) (x is the amount she can type)
