Answer:
2.14 x 10^-7
Step-by-step explanation:
There are 10 numbers behind the decimal so its 10 then you count the zeros (6) and add the 2 (like not add 2 but add it as one number) to make it 7. And since its going backwards it would be a negative -7.
Answer:
Area = 5/6 of a foot^2
Step-by-step explanation:
Formula
Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2
Givens
- b1 = 2 feet
- b2 = 3 feet
- h = 1/3 foot
Solution
Area = 1/2(2 + 3)*1/3
Area = 1/2(5)* 1/3
Area = (1/2 * 1/3) * 5
Area = (1/6) * 5
Area = 5/6
Answer:
20*(4/5)
Step-by-step explanation:
The expression you will use is :
20*(4/5) = 80/5 = 16
16 is 80 percent of 20 wich equals 4 fifths that's true
The mean is also known as the average. For this problem, we want to find out the average distance that the guesses were from the true temperature. To do this, we need to add up all of the values and divide them by the number of values we have.
Person A:
-3 + -1 + 0 + 2 = -2
4 values
Person B:
4 + -4 + 2 + -3 = -1
4 values
Person C:
8 + -2 + 5 + 1 = 12
4 values
Totals:
-2 + -1 + 12 = 9
4 + 4 + 4 = 12 values
Find average:
9/12 = 0.75
The mean value in Fatima's results is 0.75.
Hope this helps!! :)
