Answer:
3/16
Step-by-step explanation:
since the question has "and" we will be multiplying two unrelated probabilities
P(gray on 1) = 1/4
P(blue on 2) = 3/4
the second probability is not affected since we are not taking away the first space after we land on it
1/4 * 3/4 = 3/16
Part C:
y = total cost
M = minutes
You can talk on the phone only 100 minutes per month
Company A:
y = 0.04M + 5
y = 0.04(100) + 5
y = 4 + 5
y = 9 $9 per month
Company B:
y = 0.10M + 2
y = 0.10(100) + 2
y = 10 + 2
y = 12 $12 per month
Company A offers the best deal because at Company A you have to pay $9 for 100 minutes per month, and at Company B you have to pay $12 for 100 minutes per month, so you have to pay $3 less.
Part D:
1.) With a budget of $30, Company A would allow me to talk longer on the phone. I know this because for Company A, you pay $3 less per month for the same amount of minutes as Company B. This means that I will save more money with Company A, and I can buy more minutes. (something like this)
A least common multiple should have all factors of the numbers, for which we want to know the least common multiple.
5 and 8 do not have common factors, so their common multiple is 5*8=40
Answer is 40.
Let's say there were 3 questions with four answer choices each. That would mean there were 4*4*4 = 16*4 = 64 different ways to answer.
Extend this example out to 19 questions instead of 3. You'll get
4^19 = 4*4*4*...*4*4 = 274,877,906,944
The last value is one big number (not four numbers)
The large number is the answer
note: 4^19 means we have 19 copies of '4' being multiplied together. The three dots mean "continue the pattern". On your paper, you should somehow indicate to your teacher that there are 19 copies of '4' being multiplied.
Yes it is a rational number because if you divide 5 by 4 then you would get 1.25
Hope this helps you :)
