Answer:1/(8a^12)
Step-by-step explanation:
(2a^4)^-3
2^(-3) x (a^4)^(-3)
1/(2^3) x a^(-12)
1/(2x2x2) x 1/(a^12)
1/8 x 1/a^12
1/(8a^12)
Do you mean 7?
You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)
1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.
2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.
3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.
4. The o term would stay as o^2 as there are not other o terms.
To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.
Answer:
There is not enough evidence to conclude that the data supports the idea that more than 50% of people plan on voting for the levy
Step-by-step explanation:
Sample size, n = 150
Number of people that plan on voting for the levy, X = 78
Proportion of people that plan on voting for the levy:
The study is to determine whether or not the data supports the idea that more than 50%(0.5) of people plan on voting for the levy
The null and alternative hypotheses are:
Calculate the test statistics:
For a test statistic , the p-value = 0.3121
The significance value,
Since the p-value(0.3121) is greater than α(0.10), the null hypothesis will be accepted.
This means that there is not enough evidence to conclude that the data supports the idea that more than 50% of people plan on voting for the levy
Since the formula for density is mass/volume and 60 inches =983.244 cubic centimeters the density is 7.1194
I can't figure out the answer to this one i'm really sorry but anytime!
thanks
