8/30 or 4/15 or 26%
8 of the 30 seats are in the front row
Answer:
5 times
Step-by-step explanation:
First, we need to read the change in price in 2000 and 2007, from the graph.
So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.
Now, we do the same thing we always do when comparing two values - we divide them. So:
0.71 / 0.14 = 5.07
Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:
71 / 14 = 5.07
We could also divide this in the form of fractions:
71/100 / 14/100 = 5.07
There are several ways we could divide rational numbers, but the result will always be the same.
Change in price in 2007 was around 5 times greater than the change in 2000.
Answer: a. 7
Step-by-step explanation: <u>Degrees</u> <u>of</u> <u>Freedom</u> is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7
Answer:
600 m
Step-by-step explanation:
Given that :
Mina's constant pace = 1.6m/s
Time taken = 20 minutes
Abeni's pace = 1.4 m/s
Time taken = 30 minutes
Difference in the distances covered :
Recall :
Distance covered = Speed * time
Mina's distance = 1.6 * (20 * 60 seconds) = 1920m
Abeni's distance = 1.4 * (30 * 60 seconds) = 2520 m
Difference :
2520 m - 1920 m
= 600 m
The 20 character minimum is stupid but the answer is 68 Km/h
