Answer:
pounds of blueberries he need to buy more.
Step-by-step explanation:
Given:
Horace buys 2 ¾ pounds of blueberries for a pie.
He needs 48 ounces of blueberries for the pie.
Now, to find pounds of blueberries he need to buy more.
<u><em>Number of pounds Horace buys blueberries for the pie = 2 ¾ pounds.</em></u>
He needs blueberries for the pie = 48 ounces.
Now, by using conversion factor convert ounces into pounds:
1 ounce = 0.0625 pounds.
48 ounces = 0.0625 × 48 pounds.
48 ounces = 3 pounds.
<u><em>Horace needs blueberries for the pie = 3 pounds.</em></u>
Now, to get the pounds of blueberries he need to buy more we subtract number of pounds Horace buys blueberries for the pie from Horace needs blueberries for the pie:
Therefore, pounds of blueberries he need to buy more.

In binomial distribution, the standard deviation is given by :-
As per given , we have
The number of vouchers in the sample with errors is denoted by x.
p= 0.20 , n = 2000
Then ,
Hence, the standard deviation of x is 17.89.
