Answer:
They travelled the same distance and they spent the same amount of time from the 225 marker to 230 marker.
Step-by-step explanation:
Given
See attachment for graph
Required
The relationship between distance and time travelled by Kevin and Carrie
The straight line represents Kevin's journey while the curve represents Carrie's
From the graph, we can see that the straight line and the curve both start at the origin (0,0) and they both end at the same point (17,5)
Point (17, 5) represents the 230 marker (i.e. 225 + 5 - 230)
<em>Since the line and the curve meet at this point, then they travelled the same distance and they spent the same amount of time.</em>
Answer: 55
Step-by-step explanation:
Let the number of cars washed last year be denoted as x.
This year, he washed 14 fewer cars than during last year's car wash. This will be denoted as x-14.
We can then represent them in an equation as:
x + (x - 14) = 96
2x - 14 = 96
2x = 96 + 14
2x = 110
x = 110/2
x = 55
Therefore, he washed 55 cars this year
Answer: the last second one: 3/4 0.8 94%
Step-by-step explanation:
because 3/4 is smaller than one so it has to go first.
hope it helps :) pls give brainliest
Answer:
40.18
Step-by-step explanation:
According to this question, the mean of 100 observation is found to be 40. This means that the number of values in the set of data is 100. However, at the time of computation two items were wrongly taken as 30 and 27 instead of 3 and 72.
The mean is derived by dividing the sum of values in the data (Σx) by the number of observations (n) i.e.
Mean = Σx/n
For the computation error:
Mean = 40
Let x represent the sun of other 98 values except 30 and 27
n = 100
40 = x + 30 + 27/100
40 = 57 + x/100
Cross multiply
4000 = 57 + x
x = 4000 - 57
x = 3943.
Sum of other 98 values = 3943.
Now, let's find the correct mean with correct values of 3 and 72;
Mean = Σx/n
Mean = 3943 + 3 + 72/100
Mean = 4018/100
Mean = 40.18
