Step-by-step explanation:

6^2+4^2=52

7^2=49

49 is not equal to 52, so no it is not a right triangle

On a particular day, 112 of 280 passengers on a particular DTW-LAX flight used the e-ticket check-in kiosk to obtain boarding pa

Sonja [21]

Answer:

0.2348 = 23.48% probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.

Step-by-step explanation:

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Population of 280, which means that $N = 280$

112 use e-ticket check-in kiosk, which means that $k = 112$

Sample of eight passengers means that $n = 8$

Find the approximate hypergeometric probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.

This is P(X = 4). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 4) = h(4,280,8,112) = \frac{C_{112,4}*C_{168,4}}{C_{280,4}} = 0.2348$

0.2348 = 23.48% probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.

Find the rate of change and initial value. Y=mx+b

tekilochka [14]

Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24

What is the slope of the equation y- 5 = -3x?

umka21 [38]

Answer:

-3/1

Step-by-step explanation:

It's always the x value over the y value, so whatever's in the x

The endpoints of two segments are given. Find each segment length to the nearest tenth. AB¯¯¯¯¯¯¯¯: A(0, 2), B(−3, 8) and CD¯¯¯¯

sleet_krkn [62]

Step-by-step explanation:

Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.

so,

AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45

AB = sqrt(45) ≈ 6.7

CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40

CD = sqrt(40) ≈ 6.3

Can Somebody Please Explain How To Do It? THANKS

sergejj [24]

Hello from MrBillDoesMath!

Answer:

Discussion:

Solution 1:

Distance between two points (x1, y1), (x2,y2) is given by the formula

sqrt( (x1-x2)^2 + (y1-y2)^2). In our case this becomes

sqrt( (0-0)^2 + (12 -3)^2 ) =

sqrt( 9^2) =

Solution 2:

Note points D and E both have x = 0 so segment DE is a vertical segment. The length is simply the difference of the y coordinates: 12- 3 = 9 as before.

Thank you,

MrB
