The thousands place is <u /><em></em>the 9 in 39<u>9</u>,713. 7 is closer to 10 than to 0, therefore, you roundup, increasing the thousands place by one. Carry the 0 to the next 9 in the ten thousands place, and again to the hundred thousands, adding one to the 3. Therefore the answer is 400,000.<u />
Answer:
a) 0.5
Step-by-step explanation:
a)
Let T be the event that person uses trails daily and E be the event that person uses trails for exercise.
We have to find the probability that person uses the trails for exercise given that the person uses trails daily which can be denoted as P(E/T).
P(E/T)= P(E∩T)/P(T)
We are given that P(T)=0.24 and P(E∩T)=0.12. So,
P(E/T)= 0.12/0.24
P(E/T)= 0.5
Thus, the probability that person uses the trails for exercise given that the person uses trails daily is 50%
Answer:
No y
Step-by-step explanation:
Since
x=-1
is a vertical line, there is no y-intercept and the slope is undefined.
Answer:
D
Step-by-step explanation:
Given
x² + 6x - 9 = 0 (add 9 to both sides )
x² + 6x = 9
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 9 + 9
(x + 3)² = 18 ( take the square root of both sides )
x + 3 = ±
= ±
= ± 3
Subtract 3 from both sides
x = - 3 ± 3
→ D
