If k=100 - 4n what’s the value when n=60
dexar [7]
To solve this problem, start by plugging in your given n value.
This results in:
k = 100 - 4(60)

Next, simplify the parentheses by multiplying the -4 and the 60 together.
This leaves you with:
k = 100 - 240

To simplify for k, subtract 240 from 100 to get:
k = -140

So your final answer is k = -140 when n = 60

Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?
igor_vitrenko [27]

Answer:

Numbers greater than 4 are 5 and 6

So we have 2 numbers out of 6 numbers so the probability is equal to 2/6 = 1/3

And 1/3 of 12 is equal to 4

So Brian expect to roll a number greater than 4,

Four times.
