Answer:
Step-by-step explanation:
Ok, lets list the important things
- only green and white slices
- all slices same size
- spinner A has 4/5 white slices and 1/5 green slices
- spinner B has 3/12 white slices and 9/12 green slices
The 4 options are:
- spinner B lands on a green slice
- spinner A lands on a white or green slice
- spinner A lands on a white slice
- spinner B lands on a yellow slice
We already know that choice 2 is 100% probable and option 4 is 0% probability, because in option 2, the spinner A ONLY has white or green slices so the spinner must land on the slice. In option 4, no matter which spinner is spun no yellow slices are available to land on.
the chance of option 1 happening is 9/12 which is 3/4 which is 75%
the chance of option 3 of happening 4/5 which is 80%
option 1 has a 75% chance
option 2 has a 100% chance
option 3 has an 80% chance
option 4 has a 0% chance
this means that the order is:
1. option 4
2. option 3
3. option 1
4. option 2
because it is least likely to most likely.
hope this helped you out and if you need any questions feel free to ask
good luck in maths!

Step-by-step explanation:
Answer:
17.5hrs
Step-by-step explanation:
Set they worked for x hours,
10x+35=210
10x=175
x=17.5
Supposing a normal distribution, we find that:
The diameter of the smallest tree that is an outlier is of 16.36 inches.
--------------------------------
We suppose that tree diameters are normally distributed with <u>mean 8.8 inches and standard deviation 2.8 inches.</u>
<u />
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- The Z-score measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.<u>
</u>
<u />
In this problem:
- Mean of 8.8 inches, thus
. - Standard deviation of 2.8 inches, thus
.
<u />
The interquartile range(IQR) is the difference between the 75th and the 25th percentile.
<u />
25th percentile:
- X when Z has a p-value of 0.25, so X when Z = -0.675.




75th percentile:
- X when Z has a p-value of 0.75, so X when Z = 0.675.




The IQR is:

What is the diameter, in inches, of the smallest tree that is an outlier?
- The diameter is <u>1.5IQR above the 75th percentile</u>, thus:

The diameter of the smallest tree that is an outlier is of 16.36 inches.
