number of reams= 6×8 =48
number of 2 weeks 48 reams can last= 48/5= 9.6
time 48 reams of paper can last= 9.6×2= 19.2 weeks
Answer:
y = - x² - 4x - 9
Step-by-step explanation:
Given
y = - (x + 2)² - 5 ← expand (x + 2)² using FOIL
= - (x² + 4x + 4) - 5 ← distribute parenthesis by - 1
= - x² - 4x - 4 - 5 ← collect like terms
= - x² - 4x - 9 ← in standard form
Answer:
The slope
Step-by-step explanation:
<u>If the </u><u>data presentation</u><u> in Exercise 2 is varied by organizing the data into classes, the data presentation is called a </u><u>grouped frequency distribution </u><u>. If one class in such a distribution is 80-89, the lower class limit is 80 and the upper class limit is 89.</u>
What is the formula for grouped frequency distribution?
- A grouped frequency distribution shows the scores by grouping the observations into intervals and then lists these intervals in the frequency distribution table.
- The intervals in grouped frequency distribution are called class limits.
What is the formula for grouped frequency distribution?
- In other words, the mean for a population can be found by dividing ∑ m f by , where is the midpoint of the class and is the frequency.
- As a result, the formula μ = ∑ m f N can be written to summarize the steps used to determine the value of the mean for a set of grouped data.
