2. X=3
Explanation: You do the opposite of the number. Its a -3 which means subtract 3 so add 3.
6. X=15
Explanation: You do the same for 2 so do the opposite which would be 15.
I think it’s between 50-55
Answer:
5√2
Step-by-step explanation:
(5√2)^2 is 50 .........
It’s important to remember the distinction between “greatest common factor” and “least common multiple.” A factor of a particular number is a bit like a multiplicative LEGO piece that makes it up; they’re the numbers that other natural numbers can be broken down into by division. A multiple is the opposite; a number and the number that it’s multiplied by (say, 8 x 5) *become factors* of a new number (40, in this case).
When we talk about finding the “least common multiple” of a set of numbers, what we’re asking is this: if you list out multiples of each number, what’s the *first* number in those lists they all have in common? For instance, if we wanted to find the least common multiple between 3 and 5, we could list out their multiples:
3, 6, 9, 12, 15, 18, 21
5, 10, 15, 20, 25, 30
15 is the first multiple that appears in both lists, so the least common multiple of 3 and 5 is 15.
Answer:
Step-by-step explanation:
a )
probability of a computer being ancient = .99
probability of a computer being cutting-edge =.01
probability of two selected computer being old
= .99 x .99
= .98 or 98%
b )
probability of 5 selected computers being old
= .99 x .99 x .99 x .99 x .99
= .95 or 95%
c )
probability that at least one of the five selected computers is cutting-edge
= 1 - probability of 5 selected computers being old
= 1 - .95
= .05
