The answer is 50%

if you list out the possibilities, you get

(H being heads, T being tails)

HHH <- 3 heads
HHT <- 2 heads
HTH <- 2 heads
HTT
THH <- 2 heads
THT
TTH
TTT

we counted 4 of them to have at least 2 heads out of the 8 possibilities

4/8 = 1/2 which is 50%

My co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004. How many different ones digits are possible
gavmur [86]

Answer:

<h3>There must be infinitely numbers different ones digits are possible in numbers that Larry likes.</h3>

Step-by-step explanation:

Given that my co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004.

<h3>To find that how many different ones digits are possible in numbers that Larry likes:</h3>

From the given "Larry only likes numbers that are divisible by 4."

There are many numbers with one digits in the real number system that could be divisible by 4 .

<h3>We cannot say the count,so it is infinite.</h3><h3>Hence there must be infinitely numbers different ones digits are possible in numbers that Larry likes</h3>

You have 22 digs for your current volleyball season. There are 5 games left in the season. You want to break your previous recor
Lilit [14]

Answer:

The inequality is;

22 + 5x > 31

x > 1.8

Step-by-step explanation:

The number of digs to break is 31

What is available at present is 22

and 5 games left;

So the inequality will be;

22 + 5x > 31

5x > 31 - 22

5x > 9

x > 9/5

x > 1.8

But since the number of digs cannot be fractional, then the number of digs per game must be greater than or equal to 2
