Answer:
the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371
Step-by-step explanation:
From the information given:
we are to determine the probability that more than 70% of customers in the sample will need additional maintenance
In order to achieve that, let X be the random variable that follows a binomial distribution.
Then X Bin(48, 0.6)
However 70% of 48 samples is
= 0.7 × 48 = 33.6 34
Therefore, the required probability is:
= P(X> 34)
= 0.03709524328
0.0371

A
Step-by-step explanation:
<u />
From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.
So, the employee earns an additional $1000 for every 10 units sold.
To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:
1000 ÷ 10 = 100
Therefore, the employee earns an additional $100 for every one unit sold.
<u />
<u>Proof</u>
This can be proved by calculating the slope (gradient) of the graph:
where and
are two points on the line
When picking the two points, remember that the <u>y-values are in </u><u><em>thousands</em></u><u> </u><u>of dollars.</u>
<u />
Two points on the line:
(0, 30000) and (20, 32000)
Substituting these into the formula:
Therefore, the employee earns an additional $100 for every one unit sold.
Three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
<h3>How to illustrate the information?</h3>It should be noted that a common tangent simply means a line the bus tangent to more than one circle.
In this case, three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
A diagram is attached to illustrate the tangent.
