Answer:
7.6525 hours
Step-by-step explanation:
11 / 4 = 2.75 so he spent 2.75 h doing his HW.
and he spent (11/4) x 2.75 practicing piano
(11/4) x 2.75 = 7.6525
By the binomial theorem,
where
is the so-called binomial coefficient.
The term that's independent of x is the constant term, which occurs when , or . Given that this constant 240, we have
but must be positive, so
Answer:
Step-by-step explanation:
((14×3) + 1 )/3 = (43/3)
Hello!
First you have to find the probability of a pulling a penny
To find this you put the amount of pennies over the amount of coins
There are 12 coins and 5 pennies
This is a 5/12 probability
Next you have to find the probability of then pulling out a quarter
Since you already took out a coin the total amount is now 11
The probability is 4/11
You multiply the two probabilities together to get the probability of them happening one after antoher
5/12 * 4/11 = 5/33
The answer is D)5/33
Hope this helps!
A=(AB+CD)*h/2
A=(12+19)*9/2=31*9/2=279/2=139,5 in.^2
