Answer:
<h2>you can fill 40 (150ml) glasses with 5 bottles of soft drinks</h2>
Basic fact:
<em>there are 1000 ml in a litre</em>
Step-by-step explanation:
let us do
5 x 1.2
= 6
now let's turn 6 litres in ml
6 x 1000
=6000
now we need to do
6000/150
instead of doing such big numbers, lets do
600/15
=40
Well all you would have to do is subtract 25 to 5 which is 5 so $20 is how much
Variance is the difference of the number from the mean of the group of numbers then square it and find the average. In this case, we need to find the mean first. 90 + 75 + 72 + 88 + 85 = 410/5 = 82 . Now we must get the difference of each from the mean.
90 - 82 = 8
75 - 82 = -7
72 - 82 = -10
88 - 82 = 6
85 - 82 = 3
Next is to find the average of the square of the numbers.
(8^2) + (-7^2) + (-10^2) + (6^2) + (3^2) is
64 + 49 + 100 + 36 + 6 = 255. Next step is to simply divide it by 5. The numerator in calculating the variance is the sum of the square of the numbers which is 255.
Answer:
6x² - 19x + 10
Step-by-step explanation:
Given
(3x - 2)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis
= 6x² - 15x - 4x + 10 ← collect like terms
= 6x² - 19x + 10
The unit rate of the equation is 3x+7
