The answer to your question is B .
Answer:
4) 8^14
7) h^7
10) 29^8 over 10^8
Step-by-step explanation:
If the numbers have the same base, just add their exponents together. So 10 plus 4 is 14.
Same thing for the second problem, since you have the same base, just add the exponents together. 6 plus 1 is 7
The bases are the same so just add the exponents, 7 plus one is 8.
(-2.9)^8
Convert it into a fraction: -(29/10)^8
Raise the fraction to the power (8) and the numerator and denominator to that power: 29^8/10^8
Hope this helps :)
Answer:
b). Examine relationships between two categorical variables
Step-by-step explanation:
- The chi-square test of independence is used to determine if there is a significant relationship between 2 Categorical variables.
- In the data set-up for the Chi-Square Test of Independence, at minimum, your data should include two categorical variables and each categorical variable must include at least two groups.
Assuming by "20111" you mean 2011.
The difference in years is 2011 and 1990 is 21 years.
In 21 years the rate of change was "-$1850" (44,450 - 6,300).
Furthermore, this can be divided by 21 to get the AVERAGE rate of change in 1 year
21 years / -1850 = -$88.096 (3 DP)
This looks crazy hard!!!!!
