Answer:
C
Step-by-step explanation:
It's a rotation of counterclockwise 90°
You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.
The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.
We can deduce that, if x is the number of people between 16 and 19, we have
So, by the relation between the two graphs, we can deduce the total population for each age group.
Answer:
Step-by-step explanation:
- speed = distance / time
- time = distance / speed
a)
i)
<u>Time taken at the first part:</u>
ii)
<u>Time taken at the second part:</u>
- (190 - 105) / (x + 12) =
- 85/(x + 12)
b)
<u>If time is 3 hours and 15 minutes = 3 1/4 hours = 13/4 hours, the equation is:</u>
- 105/x + 85/(x + 12) = 13/4
- 4(x + 12)*105 + 4(85x) = 13x(x + 12)
- 13x² - 604x - 5040 = 0
c)
<u>Solve the equation:</u>
- 13x² - 604x - 5040 = 0
- x = [604 ± √((-604)² + 4*13*5040) ]/26 =
- [604 ± √626896]/26 =
- [604 ± 791.77]/26
- x = (604 + 791.77)/26 = 53.68 km/h (taking positive root only)
d)
- 105/x = 105/53.68 h = 1.956 h = 1 h 0.956*60 min = 1 h 57 min (rounded)
- 85/(53.68 + 12) = 85/65.68 = 1.294 h = 1 h 0.294*60 min = 1 h 18 min (rounded)
Answer:
30
Step-by-step explanation:
The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1. If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8. We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees. Since a is 3 than a gets 3 of those parts meaning a would be 30
I hope this helps and please don't hesitate to ask if there is anything still unclear!
The investigation that was carried out by the researcher illustrates a one-shot case study.
<h3>What is a one-shot case study?</h3>
It should be noted that a one-shot case study simply means a research design where a single group is observed after experiencing some treatment on a single occasion.
Since the researcher sits in the quad and records the number of minutes each student puts into studying, it's a one-shot case study.
Here, the single group of individuals are selected for observation.
