2/7, 0/7, 1/3 or 1/4 since we are not sure who catches the bus
Answer:
2/3
Step-by-step explanation:
In a year, we have 52 weeks.
Since he is supposed to have a new order for every two weeks, he needs 52/2 = 26 orders to break the company record.
After 28 weeks, he has got only 28/2 = 14 orders.
He is 4 orders behind. So he has done 14 - 4 = 10 orders.
The sales man needs 26 - 10 = 16 more orders .
Although 28 weeks is gone, we have 52 - 28 = 24 weeks left.
If he needs to make 16 sales in 24 weeks, the proportion is 16/24 = 2/3
He needs to make 2 sales every week to break the record

Answer:
And rounded up we have that n=31
Step-by-step explanation:
First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is and the critical value for this case would be:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is . And replacing into equation (b) the values from part a we got:
And rounded up we have that n=31
Answer:
y = -5
Step-by-step explanation:
<em>-</em><em>7</em> = <em>y </em><em>-</em><em>2</em><em> </em>
<em>y </em><em>=</em><em> </em><em>-</em><em>7</em><em> </em><em>+</em><em>2</em>
<em>y </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>
