The average rate of a function f(x) over an interval x = a and x = b is given by:
Given the function
The average rate of change from x = 1 to x = 2 is given by:
$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.
Area = 270 square feet, length = 18 feet
Area = Length x Width
270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet
The room is 15 feet wide.
Answer: (a) 19448 ways
(b) 5292 ways
(c) 0.2721
Step-by-step explanation:
(a) 10 county council members be randomly elected out of the 17 candidates in the following ways:
= 
= 
= 
= 19448 ways
(b) 10 county council members be randomly elected from 17 candidates if 5 must be women and 5 must be men in the following ways:
we know that there are 7 women and 10 men in total, so
= 
× 
= 
× 
= 21 × 252
= 5292 ways
(c) Now, the probability that 5 are women and 5 are men are selected:
= 
= 
= 0.2721
Answer: 1,230
Usage of 10^x form is called scientific form and it helps much in science where the calculation unit can vary from very big into very small.
In this case, you are given the number 1.230 x 10^3 and asked to express it in decimal form. Then you just simply need to multiply the number with the 10^3. The calculation would be: 1.230 x 10^3= 1.230 x 1000= 1230
