the answer is 16
8^(4/3) can be written in different ways. You can first simplify it by breaking the exponents down into 1/3 and 4. You can write it as (8^1/3)^4 (it still means the same thing). When you raise something to the one over something fraction, the denominator tells you what the root is. Because it says 1/3, it means that you're finding the cube root of something. So you can rewrite it as (3√8)^4 (the three should be sitting on top of the sign to signify that it's cube root). You then just solve from there. The cube root of 8 is 2 (2*2*2=8) so it'll simplify to (2)^4. You then solve it from there and get 16 as your answer (2*2*2*2=16).

Answer: There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Step-by-step explanation:
Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.
Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).
i.e. A person can be 90% confident that the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).
Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
6- ounce packet rate = $0.72 .
In order to find the one ounce rate, we need to divide $0.72 by 6.
On dividing 0.72 by 6, we get $0.12.
<em>Therefore, first unit rate is $0.12 per ounce.</em>
3- ounces packet rate = $0.27.
In order to find the one ounce rate, we need to divide $0.27 by 3.
On dividing 0.27 by 3, we get $0.09.
<em>Therefore, second unit rate is $0.09 per ounce.</em>
<h3>So, we can say that each pair of rates is not equivalent. </h3>
Answer:
28-7x
Step-by-step explanation:
To write the expression without grouping symbols, multiply the 7 into both terms using the distributive property.
7*4 - 7^x
28-7x
