Answer:
the next two terms are 17, 20
Step-by-step explanation:
add 3 to each term
Example
5+3 = 8
8+3= 11
11+3= 14 etc.
3 because 3•3 is 9 and 9•3 is 27
Answer:
see below
Step-by-step explanation:
1. 0 = (r + 1)(r + 8)
Using Zero Product Property, r = -1, r = -8
2. h(r) = (r + 1)(r + 8)
= r² + 9r + 8
= (r + 9/2)² - 81/4 + 8
= (r + 4.5)² - 12.25 (Complete the square)
Vertex: (-4.5, -12.25)
Answer:
test statistic.
Step-by-step explanation:
The chi-square (
) test is a non-parametric statistical test(also known as Goodness of fit test) which is used to determine if a distribution of observed frequencies differs from the expected frequencies.
Chi-square statistic uses either nominal (categorical) or ordinal level data.
Hence, When determining how well an observed set of frequencies fits an expected set of frequencies, the test statistic is
test statistic.
