It’s D
the reason why is because the multiplier must be between 1 and 10
(
1
≤
x
≤
10
)
so first more your decimal there which you get:
2.34
then just count how many numbers the decimal jumped, if the decimal moved left the exponent is positive and if it moved right, as in your number, the exponent is negative
yours moved 3
Answer:
See example below.
Step-by-step explanation:
To scale down by a factor of 1/10, multiply the side length or distance by 1/10.
Example:
If the distance was 5 then 5*1/10 = 5/10 = 1/2 is the scaled down version.
Answer: a) (1008.34,1019.658) b) (1009.24,1018.76)
Step-by-step explanation:
Since we have given that
n = 75
mean = 1014 hours
Standard deviation = 25 hours
At 95% two sided , z = 1.96
So, confidence interval would be
(b) Construct a 95% lower confidence bound on the mean life.
z = 1.65
So, confidence interval would be
Hence, a) (1008.34,1019.658) b) (1009.24,1018.76)
a. if the return trip is the same then the bird traveled 40miles
b. the time of the trip is x hours + 6/x-4
Hope this helps!
