Answer:
2.25km
Step-by-step explanation:
Calculate the total distance:
<u>9km/</u> 0.80 x 100% = 11.25km
The walker has travelled 9km, so
11.25km - 9km = 2.25km left
Answer:
c. 0.6
Step-by-step explanation:
A student cannot receive an A or a B simultaneously, so
.
Grade of A equals .30 and the probability of receiving a grade of B equals .30.
This means that ![P(A) = P(B) = 0.3](https://tex.z-dn.net/?f=P%28A%29%20%3D%20P%28B%29%20%3D%200.3)
The probability that a randomly selected student from this class will receive either an A or a B equals:
This is:
![P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.3 + 0.3 - 0 = 0.6](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%20%3D%20P%28A%29%20%2B%20P%28B%29%20-%20P%28A%20%5Ccap%20B%29%20%3D%200.3%20%2B%200.3%20-%200%20%3D%200.6)
So the probability is 0.6, and the correct answer is given by option c.
Answer:
(1,1);(11,1);(6,6);(6-4)

The easiest way to do is add or subtract 5 to the x or y value.
Answer:f(x)=2x-6
Step-by-step explanation:
10:12
15:18
i got this from doubling the first to make 5 = 10 and then that made 6 = 12. the second one was the same but tripled to make 6 = 18 and then that made 5 = 15
