Answer with step-by-step explanation:
Let
A=Student studies for a test
B=Student gets good grade on a test
The probability that a student studies for a test=P(A)=0.61
The probability that a student gets a good grade on a test=P(B)=0.79
The probability that both occur=
a.We have to find the events are independent
We know that if two events A and B are independent then
Hence, given events are not independent.
b.We have to find 
c. We have to find 
Answer:
8 hours
Step-by-step explanation:
The equation is 2.25X + 3.50 = 21.50
X represents the unknown amount of hours she worked. 2.25 is the cost per hour. 3.50 is the fee she charges for every gig. That fee only happens once a gig so naturally it wasn't the number x was placed with.
2.25X + 3.50 = 21.50
2.25X + 3.50 - 3.50 = 21.50 - 3.50
2.25X = 18
<u>2.25X</u> = <u>1</u><u>8</u>
2.25 2.25
X = 8
Answer:
Angle 6 forms a pair of alternative exterior angles with angle 3.
Answer:
The value under the radical is 3
Step-by-step explanation:
9^(2/3) This means 9 squared then find find the cube root of the answer.
9^(2/3)=∛(9^2 )
= ∛81
= ∛(3×3×3×3) = ∛(3)³ ₓ ∛3
= 3∛3
The value under the radical is 3
I hope this now shows clearly the number under the radical is 3.
