A cheap way to go about it is, use the LCD and multiply both sides by it.
now, notice the denominators, x, 4, 4x, clearly the LCD is 4x, so let's multiply both sides by that, to do away with the denominators,
Answer:
B
Step-by-step explanation:
+ 4 = 1 ( subtract 4 from both sides )
= - 3 ( multiply both sides by 5 to clear the fraction )
x = 5 × - 3 = - 15 → B
the number of adult ticket's sold = 35
And the number of child ticket's sold = 2 x 35 + 12 = 70 + 12 = 82
Step-by-step explanation:
Answer: 2.4
Step-by-step explanation:
Given : The weights, in pounds, of the cats in an animal adoption center are normally distributed.
The confidence interval is (7.9,12.7) (1)
Let be the sample mean of the weights, in pounds, of the cats in an animal adoption center.
We know that the confidence interval for population mean is given by :-
(2)
From (1) and (2)
Subtracting (3) from (4), we get
Hence, the margin of error is E = 2.4
