Answer:

He can grade 1.25 assignments in 1 minute.

Step-by-step explanation:

Because the teacher can grade 25 assignments in 20 minutes, we can dive 25 by 20 to get the constant rate.

25/20\\1.25

So he can grade 1.25 assignments in 1 minute.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
Lisa [10]

Answer:

0.0064

0.00032

Step-by-step explanation:

Given the details:

P(X > 3), n = 5, p = 0.2

The binomial distribution is related using the formula:

P(x = x) = nCx * p^x * q^(n-x)

q = 1 - p = 1 - 0.2 = 0.8

P(X > 3) = p(x = 4) + p(x = 5)

P(x = 4) = 5C4 * 0.2^4 * 0.8^1 = 5 * 0.2^4 * 0.8^1 = 0.0064

P(x = 5) = 5C5 * 0.2^5 * 0.8^0 = 1 * 0.2^5 * 0.8^0 = 0.00032

Kong took 15, percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 85
Evgen [1.6K]

Hello!


If Kong took a 85 second and we if Nolan took 15 slower then Nolan took a 72.25 second test. First you would find 14 percent of 85 then that is 12.75. Minus that from 85 and you get 72.25.


Hope It helps!

Graph and Label the Points on the coordinate plane below
Lapatulllka [165]
In order to graph these, you need to understand the X and Y axis.

The X-Axis contains the first number in your ordered pair, and goes left, right (horizontally) for example the first ordered pair you have.

(2,5 1/2). To do this, move 2 spaces to the right on your X-axis. now go 5 and a half spaces up, and plot the point.


(-2 1/2, 0.5) For this one, you move 2 and a half spaces to the left on the X-axis, and half a space up. put a point there.


(3.5, -4 1/2) move 3 and a half spaces to the right on your X-axis, and go 4 and a half spaces down. put a point there.

let me know if you have questions! :)
