So 5^2 -4^2 is 25-16 which is 9
6^2/9 is 36/9 which is 4 +9 is 13

According to the Department of Transportation, 27% of domestic flights were delayed in the last year at JFK airport. Five flight

Mars2501 [29]

Answer:

The probability that all the five flights are delayed is 0.2073.

Step-by-step explanation:

Let X = number of domestic flights delayed at JFK airport.

The probability of a domestic flight being delayed at the JFK airport is, P (X) = p = 0.27.

A random sample of n = 5 flights are selected at JFK airport.

The random variable X follows a Binomial distribution with parameters n and p.

The probability mass function of X is:

$P(X=x)={5\choose x}0.27^{x}(1-0.27)^{5-x};\ x=0,1,2...$

Compute the probability that all the five flights are delayed as follows:

$P(X=5)={5\choose 5}0.27^{5}(1-0.27)^{5-5}=1\times 1\times 0.207307=0.2073$

Thus, the probability that all the five flights are delayed is 0.2073.

BRAINLIESTTT ASAP!!! PLEASE HELP ME :) Explain your answer please and show your steps/work.

algol [13]

Answer:

√x

Step-by-step explanation:

First, simplify -3⁄6 to -½. Next, according to the Negative Exponential Rule, move the denominator to the numerator to get x¹\²:

bⁿ = 1\b⁻ⁿ

Then, according to the Definition of Rational Exponents [part I], rewrite this as a radical, which in this case would be √x. This is when your numerator is 1:

ⁿ√aᵐ = aᵐ\ⁿ

The function rule C = 40n + 210 relates the number of months n to cost in dollars C of a phone plan and budget phone. Make a tab

Viefleur [7K]

Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

$C(n) = 40n + 210$

After 2 months:

This is C(2). So

$C(2) = 40(2) + 210 = 80 + 210 = 290$

After 12 months:

This is C(12). So

$C(12) = 40(12) + 210 = 480 + 210 = 690$

After 24 months:

This is C(24). So

$C(24) = 40(24) + 210 = 960 + 210 = 1170$

Table:

Input - Output

2 - $290

12 - $690

24 - $1170
