In a certain Algebra 2 class of 27 students, 11 of them play basketball and 9 of them play baseball. There are 11 students who p

<h2>Answer:</h2><h2>The probability of students who play both basketball and baseball = $\frac{4}{27}$ </h2>

Step-by-step explanation:

In a certain Algebra class,

The total number of students = 27 students

Let the students playing basketball be represented as A and baseball as B.

The students who play basketball, A= 11

The students who play basetball,B =9

The students who play neither sport, = 11

The students who play both basketball and baseball, = ?

By formula, P(AUB)=P(A)+P(B)-P(A∩B)

Substituting the values in the equation, we get

P(AUB) = $\frac{11}{27} + \frac{9}{27} - \frac{16}{27}$

P(AUB) = $\frac{4}{27}$

The probability of students who play both basketball and baseball = $\frac{4}{27}$

max2010maxim [7]

Answer:

12z−32

Step-by-step explanation:

Distribute:

=(−4)(z)+(−4)(3)+(−4)(5)+(−4)(−4z)

=−4z+−12+−20+16z

Combine Like Terms:

=−4z+−12+−20+16z

=(−4z+16z)+(−12+−20)

=12z+−32

Water flows from the bottom of a storage tank at a rate of r(t) = 400 − 8t liters per minute, where 0 ≤ t ≤ 50. Find the amount

qwelly [4]

Answer:

Step-by-step explanation:

Just integrate r(t) with respect to t

Integrate r(t) dt = 400t -(4t^2)/2 + C

= 400t -4t^2 + C

where C is a constant

then replace the above answer with 30 and 0, then do subtraction for both answers

hence the amount of water flows during first 30 mins is

= {400*30 - 4*(30)^2 + C} - {400*0 - 4*(0)^2 + C}

= 12000 - 3600

= 8400 liters
