The amount payed each month by Andy is £ 504
<u>Solution:</u>
Given that, Andy is buying a car.
He negotiated a 7 percent decrease on a 6500 car.
Then, amount to be paid = 6500 – 7% of 6500
He will pay the full balance in 12 equal monthly payments.
We have to calculate the amount paid each month
Hence, Andy has to pay £ 504 approximately each month.
Answer:
Pr(≥ 70%) = 2/5 = 0.4
Step-by-step explanation:
This question is incomplete as we can't get an exact answer without the dot plot diagram.
We can tell from the question, we are to determine the probability of having ≥ 70% students that play sports
The dot plot diagram used in solving the question has been attached.
Total number of samples = 20
From the dot plot, 50% of students play sport. That is, 50% have more people playing sport than others.
The chance of getting a sample proportion of 70% or greater= probability of students that like sports ≥ 70%
= (sum of people that like sports ≥ 70%)/(total number of sample)
Pr(≥ 70%) = (4+3+1)/20
Where Pr = probability
Pr(≥ 70%) = 8/20
Pr(≥ 70%) = 2/5 = 0.4
