Answer:5.4 km
Step-by-step explanation:
Answer:
Not a factor because there is a remainder.
Step-by-step explanation:
Let's use synthetic division to solve this..
-1 ║ 2 | 4 | -2 | -8
║ | -2| -2 | 4
║ 2 | 2| -4 | -4
PS: if anyone knows a better way to do a synthetic division chart please let me know.
To compare whether or not two fractions are equivalent, they must have the same denominator.
What is a common denominator you can make between
and
? Some possible options are 5n or 10n.
I'll make both denominators 5n:1)
already has 5n in the denominator.
2) To get 5n in the denominator for
, you want to divide both the numerator and denominator by 2 (same as multiplying top and bottom by
). Since you're doing the same thing to the numerator and denominator, you are not changing the value of the fraction:
Now
compare the two fractions. Since
, your fractions are equivalent!

Answer: They are equivalent
Answer:
65.04<x<68.96
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = x ± z*s/√n
x is the mean = 67
z is the 95% z score = 1.96
s is the standard deviation = 8
n is the sample size = 64
Substitute;
CI = 67 ± 1.96*8/√64
CI = 67 ± 1.96*8/8
CI = 67 ± 1.96
CI = (67-1.96, 67+1.96)
CI = (65.04, 68.96)
Hence the confidence interval for the mean of the population is between 65.04<x<68.96
