Answer:
The number of heads observed is 121.14 heads
Step-by-step explanation:
The formula for the z-score of a proportion is given as follows;
Where:
= Sample proportion
p = Population success proportion = 0.5
q = 1 - p = 1 - 0.5 = 0.5
n = Number in of observation = 200
z = 2.99
Hence, we have;
Therefore;
= 0.6057
∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.
Answer:
New cars sold = 20,
Used cars sold = 25
Cars serviced = 290
Step-by-step explanation:
In a month they sold fifteen less used cars than twice the number of new cars.
Lets say 'x' number of new cars were sold, then:
The number of used car sold is:
In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:
Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:
Solving for 'x' we get:
Therefore, the number of new cars sold in that month is 20.
Number of used car sold
Number of cars serviced
We can also cross check by summing them up:
