Answer:
The answer to your question is the second option
Step-by-step explanation:
Expression
Process
1.- Divide the fraction in numerator and denominator
a) Numerator
[(x²y³)⁻²]³ = (x⁻⁴y⁻⁶)³ = x⁻¹²y⁻¹⁸
b) Denominator
[(x⁶y³z)²]²= (x¹²y⁶z²)³ = x³⁶y¹⁸z⁶
2.- Simplify like terms
a) x⁻¹²x⁻³⁶ = x⁻⁴⁸
b) y⁻¹⁸y⁻¹⁸= y⁻³⁶
c) z⁻⁶
3.- Write the fraction
85.5 as a fraction is 85 2/10 which is simplified to 85 1/5
Answer:
You should select at least 216 statistics professors.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
You should select at least 216 statistics teachers.
This question does not make sense. There cannot be that many equal signs.
x + 3x + 3x = 3
x = 3/7
Answer:
5. reduction 6.enlargement
Step-by-step explanation:
if the scale factor is greater than one (for example) 2 then it will enlarge, but if the scale factor is less than one, it is reduced.
An in #5, from A to B the rectangle goes from bigger (A) to smaller (B) so it must have a smaller scale factor in order to reduce ,and in #6 A is smaller and B is bigger which goes back to the concept of it must have a bigger scale factor in order for it to enlarge. But all in all you can see in #5 A. is the bigger rectangle so in order to become the rectangle in B. it must reduce.
