Answer:

John has 2 dollars and 46 cents left after his purchases.

Step-by-step explanation:

50 - 17.50 = 32.50

32.50 - 24.99 = 7.51

7.51 - 6.99 = 0.52

0.52 + 5.00 = 5.52

5.52 - 3.06 = 2.46

A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fai
azamat

Answer:

Probability (Both fail)  = 0.001369

Probability (None fails) =0.927369

Probability (at least one fails)   = 0.072631

Step-by-step explanation:

given data

Probability (fail) P = 0.037

two alternators is  independent

solution

we get here first  probability that both will fail will be

Probability (Both fail) = 0.045²    ................1

Probability (Both fail)  = 0.001369

and

now we get probability that neither will fail

Probability (None fails) = (1-0.037)²              ...............2

Probability (None fails) =0.927369

and

now we get probability that at least one fails

Probability (at least one fails)  = 1 - Probability (non fails)     .................3

Probability (at least one fails)   = 1 - 0.927369

Probability (at least one fails)   = 0.072631

What is the y-intercept of the equation 3x - 4y = 16?<br> A. -4<br> B. 0<br> C. 3/4<br> D. 16
polet [3.4K]
You can find the y-intercept by plugging in zero for x and solving. We know that the value will always be zero when the point is on the y-axis, which is the y-intercept.
3(0) -4y = 16
-4y = 16
divide both sides by -4
y = -4
Letter A
