Answer:
Average: 4
Standard Deviation: 0
Step-by-step explanation:
Because we don't know how each student did we are going to assume that they all got 20% of the questions right
20% of 20 is 4
Which means that we can assume each student got 4 questions correct
Because all entries are the same the standard deviation is 0
It is the 60 percent of 200 hundred dollars
When rates<span> are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called </span>unit rates<span>. To determine the rate, we just divide the distance traveled by the time it takes. Therefore, the rate of the plane would be
rate = 256 / 30(1/60) = 512 miles per hour</span>
<span>To get the bigger number, divide by 2 the sum of the given sum of the numbers and their difference. In this case-
(226 + 200)/2 = 426/2 = 213.
To get the smaller number, divide by 2 the difference of the given sum of the numbers and their difference. In this case -
(226 - 200)/2 = 26/2 =13.
The two numbers are 213 and 13.
The bigger number is 213</span>
