Annual snowfall in Anchorage, Alaska, is normally distributed with a mean height of 76 inches and a standard deviation of 4.7 inches. What is the probability this year that it will snow between 71.4 and 80.7 inches in Anchorage? 67.75% 54.71% 38.14% 23.22%
Answers
Answer:
67.75%
Step-by-step explanation:
Given:
Given that:
µ = 76 ; σ = 4.7
P(x < 80.7) - P(x < 71.4)
Obtain the standardized score, Z ; x = 71. 4
Zscore = (x - μ) / σ
P(x < 71.4) = (71.4 - 76) / 4.7
P(x < 71.4) = - 4.6 / 4.7
P(x < 71.4) = - 0.9787
P(z < 0.9787) = 0.16386
x = 80.7
P(x < 80.7) = (80.7 - 76) / 4.7
P(x < 80.7) = 4.7 / 4.7
P(x < 80.7) = 1
P(z < 1) = 0.84134
0.84134 - 0.16386 = 0.67748 = 67.748% = 67.75%

The interqurtile range is q3 - q1
Q3 is 16.5 and the q1 is 12
16.5 - 12 = 4.5
Step-by-step explanation:
Answer is 4.5
Interquartile range (IQR) :
The interquartile range shows the range in values of the central 50% of the data. To find the interquartile range, subtract the value of the lower quartile ( or 25%) from the value of the upper quartile ( or 75%).
=> IQR = Q3 – Q1
Here,
First Arrange the data in ascending order.
11, 12, 12, 13, 14, 15, 16, 17, 18
Median = 14.
Q1 = 12 and Q3 = 16.5
IQR = Q3 - Q1 => 16.5 - 12 = 4.5
Answer is 4.5

A cash withdrawal of R5000 was made at signet blue on the 20/05/2019.Calculate what percentage the withdrawal fee is of the transaction amount
Answers
Answer: 1%
Step-by-step explanation:
Question is incomplete as it lacks the details of the withdrawal fee.
We shall assume one so that we can use it for calculation so that you can understand the methods.
Assume withdrawal fee of R50.
The withdrawal amount was R5,000 and the cost to withdraw was R50.
The percentage of the withdrawal fee in relation to the total amount is:
= Withdrawal amount / Total amount * 100%

Answers
Answer:
Third choice
Step-by-step explanation:
Let's see, let's write the numbers in order.
-6,-2,1,1,4,4,14
So we can see that yes, indeed, it could be either -6 or 14.
We can also rule out the first choice and the last choice, because they lack in common sense. -6, being lesser, would not raise the mean, it would lower it. 14, being the greatest, would not lower the mean, it would raise it.
Now let's put our numbers through trial. Find the mean of the whole set.
-6+-2+1+1+4+4+14 = 16
16/7
16/7 is approximately 2.3. We round to the nearest tenth because the numbers in the answers (1.9) are rounded to the nearest tenth.
Now we will exclude 14 to see how much it changes.
-6+-2+1+1+4+4 = 2
2/6 = 1/3
1/3 is approximately 0.3. We can see that the mean has decreased by around 2 just from removing the 14.
Now let's exclude -6 and see how much it changes.
-2+1+1+4+4+14 = 22
22/6 is approximately 3.7. We can see that the mean has increased by around 1.4.
Both the second and the third choice are plausible, but we are looking for the outlier, meaning the one that is further away from the rest of the numbers. The mean decreased by around 2 (which is near 1.9) when 14 is removed, which is greater than 1.4 (or 1), so we can assume that the third choice is the answer.
We can also back this up by finding how much each number is close to the mean. -6 is closer to 2.3 than 14, because if you add 6 to 2.3 (to get the distance between them), it is 8.3, while if you subtract 14 by 2.3, you get 11.7, which is greater than 8.3
Another way to double check this is to see how far away the numbers are from the rest of the numbers. This is not a very accurate way, but it can be useful in double checking. -6 and -2 are only 4 units apart, while 4 and 14 are 10 units apart. 10>4, naturally.
A cube has an edge length of 10 centimeters. What is it’s volume, in cubic centimeters?
Answers
Answer:
volume=360000 cubic cm.
Step-by-step explanation:
V=a^2
A=6 x s^2
Side = 10
6 times 10^2
10^2=100
6 times 100
Area=600
v=Area(600)^2
Answer:
Step-by-step explanation:
The volume of any rectangular prism is
V=xyz, where x,y,z are its dimensions.
A cube is a special case where x=y=z, meaning all sides are the same, so for a cube
V=s^3, and in this case the cube has sides equal to 10cm so
V=10^3 cm^3
V=1000 cm^3

trash bags sells for $8. Determine
how many rolls of trash bags each
person must sell to make $300.
