Answer:
0.13591.
Step-by-step explanation:
We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.
We know that z-score tells us that a data point is how many standard deviation above or below mean.
To solve our given problem, we need to find area between z-score of -2 and -1 that is 
.
We will use formula 
to solve our given problem.
Using normal distribution table, we will get:
Therefore, the probability of randomly selecting a score between 1 and 2 standard deviations below the mean would be 0.13591.
Step-by-step explanation:
a) Mount Logan, in southwestern Yukon, is 5959 m tall.
b) The diameter of an apple is 6.4 cm.
c) The largest brown bear, the Kodiak, is 2.44m in length.
The reason is that we need to use appropriate estimation method and approximation to present a meaningful figures in our life. Take the size of the apple as an example, we won't care it is one mm bigger or smaller.

Answer:
7 : 8
Step-by-step explanation:
70 : 80 divided by 2 =
35 : 40 divided by 5 =
7 : 8
OR
70 : 80 divided by 10 =
7 : 8
Total crude oil production in the Louisiana Field during the month of April 2018 was 3842000 barrels.
As April has 30 days , so in 30 days the number of barrels produced were = 3842000
Hence in one day the number of barrels produced were =
= 128066.66 barrels
So converting it to near whole number, we get 128067 barrels.
Hence the average daily production was 128067 barrels.
