(5/8) × 48 = (8/15) × n
Multiply by the inverse of the coefficient of n. That inverse is 15/8.
n = (15/8)×(5/8)×48 = (75/64)×48 = 225/4 = 56 1/4
5/8 of 48 is equal to 8/15 of 56 1/4
14.99n+4.99 represents the cost of n cds
(14.99x3) + 4.99 =
34. 97 + 4.99= $39.97- 0.1= $39.96
3 CD s cost $39.96
Answer:
the approximate value of the square root of 8 is 2.828
Answer:
(25.732,30.868)
Step-by-step explanation:
Given that in a random sample of 42 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.09.
Since only sample std deviation is known we can use only t distribution
Std error = 
t critical for 99% two tailed 
Margin of error
Confidence interval lower bound = 
Upper bound = 
Answer: Your choice is the first one above.
In our inequality, x is our unknown, so that is "a number" in the wording above. 1/2x means half the number. So we have half a number plus 3/4. Of course "plus" means sum, so we have "the sum of half a number and 3/4" so far. The inequality sign is greater than or equal to. That means that the left side CAN equal the right side and it can also be greater than the right side, but it's not ok to be less than the right side.
