30/12 in simplest form is 5/2 (cause 6 * 5 = 30 and 6 * 2 = 12)
40/16 in simplest form is 5/2 (cause 8 * 2 = 16 and 8 * 5 =40)
so yes they're equivalent;
30/12 = 40/16
Hope that helps :D have a nice day!
Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
LCM of 15 and 60 is 60.
GCF of 15 and 60 is 15.
Answer: 3 pints of paint
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder: 2 π r2 + 2 π r h
Where r is the radius and h is the height of the storage.
Replacing with the values given:
SA = 2 π (2)^2 + 2 π (2) 9
SA= 2 π (4)+ 2 π 18
SA= 138.23 ft2
Since 1 pint of paint covers 50 ft2 , we have to divide the surface area by the area that each pint of paint covers:
138.23 / 50 = 2.76 = 3 pints of paint
Feel free to ask for more if needed or if you did not understand something.
