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:
x = 9.8
Step-by-step explanation:
They are same shape so we just get the ratio.
AB/JK = BC/KL
5 / 7 = 7 / x
5x = 49
x = 9.8
There is no model for us to shade in
Answer:
14p-35
Step-by-step explanation:
Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
