Answer:
The answer is stratified.
Step-by-step explanation:
Answer:
a₄ = - 15
Step-by-step explanation:
Using the recursive formula and a₁ = 17 , then
a₂ = a₁ - 8 = 17 - 8 = 9
a₃ = a₂ - 8 = 9 - 8 = 1
a₃ = a₂ - 8 = 1 - 8 = - 7
a₄ = a₃ - 8 = - 7 - 8 = - 15
Answer:
(A) Scatterplot
Step-by-step explanation:
The most helpful visualization to spot outliers would be a scatterplot.
When collecting data on a scatterplot, you can see how the results are similar and which areas have the most answers and such.
There can be multiply outliers on a scatterplot, and they stand out because while most answers will be clumped together, the outliers will not.
Answer:
Step-by-step explanation:
A hole is an input value that makes both numerator and denominator equal to zero.
<u>Let's factorize the numerator and denominator:</u>
- 3x² - 108 = 3(x² - 36) = 3(x + 6)(x - 6)
- x² + 2x - 24 = x² + 6x - 4x - 24 = x(x + 6) - 4(x + 6) = (x - 4)(x + 6)
<u>We have same factor of x + 6:</u>
- x + 6 = 0
- x = - 6 is a hole
