Answer:
Step-by-step explanation:
has the form 
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
Answer:
True
Step-by-step explanation:
Considering the above definition of Pooled Variance, the correct answer is TRUE.
This is because Pooled variance is used to determine the reasonable estimates of variance, where several repeated tests are expected at each value.
This helps to provide greater precision estimates of variance.
Answer:
(3)(c) + 43 ≥ 100
Step-by-step explanation:
Given:
Total number of friends = 3 friends
Number of card already have = 43
Total number of card at least want to collect = 100
Find:
Inequality
Computation:
Assume;
Same number of card each friend collect = c
Total number of card at least want to collect ≤ (Total number of friends)(Same number of card each friend collect) + Number of card already have
Total number of card at least want to collect ≤ (3)(c) + 43
100 ≤ (3)(c) + 43
(3)(c) + 43 ≥ 100
Format: y = mx + b
m = slope, b = y intercept
Solution: slope: -2, y intercept: 0
Answer:
5 to 2
Step-by-step explanation:
You can simplify both 20 and 8 by 4.
20/4 = 5
8/4 = 2
