True because it had a strict pattern and measurable proportions. <span />
Answer:
B. (x - 2)(x + 2)
Step-by-step explanation:
The answer is b. If you have (x + a)(x - a), the variables will cancel each other out. For example, if we take the answer (x - 2)(x + 2) and factor it out, we get:
x² - 2x + 2x - 4
Then it becomes just:
x² - 4 because the x to the power of one has been canceled. This proves his theory wrong.
Answer:
The next terms of the sequence 33, 25, 17 is:
Step-by-step explanation:
An arithmetic sequence has a constant difference 'd' and is defined by
computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same and equal to
The first element of the sequence is:
now substituting and in the nth term
<u>Determining the 4th term:</u>
We already got the nth term of the Arithmetic sequence
substitute n = 4
<u>Determining the 5th term:</u>
substitute n = 5 in the nth term
Thus, the next terms of the sequence 33, 25, 17 is:
Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean :
Standard deviation :
a) The formula for z -score :
Sample size = 1
For x= 63 in. ,
The p-value =
Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,
The p-value =
Thus , the probability is approximately=0.8810.
