Answer:
The answer is x = -5
Step-by-step explanation:
2/3x - 1/2 = 1/3 + 5/6. First, multiply the entire equation by the common denominator of 6. This will get rid of the fractions. :)
6(2/3x - 1/2) = 6(1/3 + 5/6x)
4x - 3 = 2 + 5x subtract 5x from both sides
4x - 5x - 3 = 2 add 3 to both sides
4x - 5x = 2 + 3 combine terms
-x = 5 multiply by -1 to make x positive
Answer:
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
Step-by-step explanation:
The interpretation of a x% confidence interval of proportions being between a and b is that:
We are x% sure that the true proportion of the population is between a and b.
If the 95% confidence interval estimating the proportion of students supporting the fee increase is (0.75; 0.85), what conclusion can be drawn
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
Answer: five
Step-by-step explanation:
Answer:
7:50
Step-by-step explanation:
We need both measures in the same units. Let's convert meters to cm.
1 m = 100 cm, so 3 m = 300 cm
Now we write the ratio and reduce it.
42 cm to 3 m =
= 42 cm to 300 cm
= 42:300
= 14:100
= 7:50
