To find the mean transaction amount. We need to understand mean first.
Mean (or average) is a number that expresses the central value in a set of data, which is calculated by dividing the sum of the values in the set by their number of values.
Here, the transactions shown are
$250, -$60, -$94, $300, and -$186. So there are 5 transactions.
Now mean transaction amount is given by:
So, the mean transaction amount over 5 transactions is $42.00.
Answer:
1. D
2. C
3. C
4. D
5. B
Step-by-step explanation:
1. 20 times 3/5 equals 12
2. 1/5 times 8 equals 8/5 or 1 3/5
3. 2/3 of 93 equals 62
4. 3/5 of 30 equals 18
5. 2/3 times 5 equals 10/3 or 3 1/3
1.5 gallons of paint will cover 675 square feet
2(10.7r - 9.5) = 33.8
10.7r
this means the number is times a variable.
10.7r - 9.5 = 1.2r
2 x 1.2r = 33.8, so we need to find the value of the variable for 1.2r
the variable that makes sense to me would be approx.14.085, so 1.2r x 2 = approximately 33.8 if you round 14.085 to the nearest tenth.
so I would say it is 14.1. hope I helped you :)
Answer:
3.25 pounds
Step-by-step explanation:
x + 4 (1/2) + 3 (1/2) = 11
x + 4.25 + 3.5 = 11
x + 7.75 = 11
x = 11 - 7.75
x = 3.25 pounds
