With multiplication, there are a few handy rules to remember:
If you multiply an even and an even, the answer will be even!
If you multiply an odd and an odd, the answer will be odd!
If you multiply an even and an odd, the answer will be even!
Knowing this, if we go back and look at the numbers Evan is trying to multiply, we can try to use these rules!
The last number of that really big number is a 7, which is odd, and the number 2 is even, and because we know that an odd number times an even number is an even number, Evan will be right!
A matrix A is identified as
and matrix B is identified as
.If the number of columns in A is the same as the number of rows in B, then you can multiply the matrices together. The product matrix, then, is made up of what's left over: rows from A and columns from B. So your answers above are, in the first blank: columns, and in the second blank: rows.
Answer:
The event x is a discrete random variable because the values of the random variable are countable and each possible outcome is equally likely
Step-by-step explanation:
A) Explaining why x is a discrete random variable
The event x is a discrete random variable because the values of the random variable are countable and each possible outcome is equally likely. A discrete random variable is variable that contains a countable number of values contained in it and each value stands an equal chance i.e The probability of each value/outcome is between 0 and 1
Answer:
14 minutes
Step-by-step explanation:
4 x every 100 bottles
100, 200, 300 = 3
4 x 3 = 12
if 4 minutes is for every 100 bottles, then 50 is half of 100. so 4 divided by 2 is 2
12 + 2 = 14
