neonofarm [45]

Answer:

1.) $640 2.) 7 years.

Step-by-step explanation:

1000 x .2 = 200 1 yr

1000 - 200 = 800

800 x .2 = 160 2 yrs

800 - 160 = 640

640 x .2 = 128 3 yrs

640 - 128 = 512

ANYWAYS THIS WOULD TAKE TO LONG! SO HERE IS THE ANSWER TO B.

Step-by-step explanation:

covert fraction to decimal we get,

-3/2 = -1.5 and 5/3 = 1.70

and any number that lies between these two numbers which is terminating and non repeating or non terminating repeating.. that are the numbers that you need.

The probability that a student pilot passes the written test for a private pilot's license is 0.7. what is the probability that

zhenek [66]

Probability = 0.063 Fourth try = 0.0973 Let X be the number of failed attempts at passing the test before the student passes. This is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7 and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p) xp. The probability P that the student passes on the third try means that there were x = 2 failed attempts or P = nb(2, ; 1, .7) = (.3)2 (.7) = 0.063 . The probability that the student passes before the third try is that there were two or fewer failed attmpts, so P = P(X â‰¤ 2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0 (.7) + (.3)1 (.7) + (.3)2 (.7) = 0.973 .

Explain the rules for multiplication and division to convert units. How do you know when to multiply and when to divide to conve

Dima020 [189]

Well, units divide and multiply just like numbers. That's why Area is in units of distance squared (cm × cm = cm²) and volume is cubic distance (m × m × m = m³).

Likewise other mathematical operations can be performed on them, including division where they can cancel out of the equation.

For instance, a rate, speed, slope or conversion factor is usually one unit divided by another unit. Like so...

speed = 5 meters per second
$= \frac{5m}{1sec}$

If you are given a distance traveled, let's say 100 meters and asked to solve for time it takes to get there. You would divide by the speed so that meters cancel leaving only time.

** Of course to divide by a fraction is to flip and multiply so really you're just multiplying by it, making sure the same units are diagonal and cancel out like so:

$100 m * \frac{1sec}{5m} = 20 sec$

Hope this helps!
