The expanded form of 584 is:
584 = 500 + 80 + 4
Therefore:
3 · 584 = 3 · ( 500 + 80 + 4 )
Then we will use Distributive property : we can multiply a sum by muptiplying each addend separately and then add the products.
3 · 500 + 3 · 80 + 3 · 4 = 1,500 + 240 + 12 = 1,752
Finally: 3 · 584 = 1,752.
Answer:
A table divided into cells by category with counts for each category in each cell. For example, let's say you were counting the number of cars and trucks that drove down a road each day over a 5-day week. Your categories would be vehicle and day. You could summarise this as a frequency table:
Step-by-step explanation:
Answer:
180 in2
Step-by-step explanation:
surface areas of similar solids are proportional to the square of their corresponding sides
area of larger/90 = 10^2/5^2
area of larger = 90(100/25) = 180 in^2
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
