Answer:
Given an expression with a rational exponent, write the expression as a radical. Determine the power by looking at the numerator of the exponent. Determine the root by looking at the denominator of the exponent. Using the base as the radicand, raise the radicand to the power and use the root as the index
Step-by-step explanation:
example
Answer:
E) An observational study using a stratified sample.
Step-by-step explanation:
This study is not an experiment because the customers were not subjected to any treatment but just observation from those selected. Also, the sampling method used was stratified sampling because we see that random samples were selected independently from two unique populations which are population of those that purchased computers and those that offer tech support.
Therefore the correct option is E.
Answer: 7 cups
Step-by-step explanation:
2 1/3 cups - convert this into a fraction
2 1/3 = 7/3
Tripled is 3 times
So multiply 2 1/3 cups by 3
7/3 * 3 = 7 cups
The correct answer is A. Sandra ran a faster time.
7.06 is less than 7.60
Hope this helps!
The value of c is 
Explanation:
Given that the trinomial is 
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,
From the trinomial, the value of b is given by
Substituting the value of b in the above formula, we have,
Squaring both the numerator and denominator, we have,
Thus, the value of c is which makes the trinomial a perfect square.
