Answer:
4/3 or 1 1/3
Step-by-step explanation:
So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.
(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).
Hope this helped :)
95% confidence interval = 62.6 + or - 1.96 x 10.4/sqrt(60) = 62.6 + or - 1.96 x 1.343 = 62.6 + or - 2.63.
Therefore, there is a 95% chance that the population mean would lie between 59.91 liters and 65.29 liters.
Answer:
Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.
The newspaper has 240000 readers
<em><u>Solution:</u></em>
Given that, Local newspaper has letters to the editor from 60,000 people
This number represents 25% of all of the newspaper's readers
To find: Number of newspaper readers
Let "x" be the number of all newspaper readers
From given statement,
60,000 people = 25% of all of the newspaper's readers
60, 000 = 25 % of x
Solve the above expression for "x"
25 % of x = 60000
Thus the newspaper has 240000 readers
