Answer:
The class width is 20
Step-by-step explanation:
In a frequency or a relative frequency distribution the class width is calculated as the difference between the lower or upper class limits of consecutive classes. A point to note is that all the categories or classes usually have the same class width.
We use the first two classes to calculate the class width by using their respective upper limits;
Class width = 89 - 69
Class width = 20
Series is 15, 12, 9…,
Difference between terms is 3
By Arithmetic progression
a_{n}=a_{1}+(n-1)d
a_n = the nᵗʰ term in the sequence
a_1 = the first term in the sequence
d = the common difference between terms
So nth term is a(n) = 15 + (n-1)*3
= 15+ 3n -3
= 12 + 3n
Answer:
81 inches squared
Step-by-step explanation:
You just multiply the area by the hight and get your answer
"How much more than" hints that you need to subtract the original weight (10 oz.) from the current weight (15 pounds, 3 oz.).
Important: 16 oz. = 1 lb.
I'd suggest that you convert 15 lb, 3 oz. to oz, so that you can easily compare the cat's mature weight to its weight at 2 weeks.
15 lb 3 oz
- 10 oz (subtract 10 oz)
--------------------
? This is "how much more he weighs now."
Example: convert 2 lb 11 oz to oz.
Solution: (2 lb) (16 oz) / (1 lb) + 11 oz. Note how "lb" will disappear.
