Answer:
Percentage of the students scored higher than 89% = 65.87%
Step-by-step explanation:
We need to find the percentage of students who scored higher than 89% given mean = 84 and standard deviation = 5.
We can find the percentage of students who scored higher than 89% by using z-score.
The formula for z-score is:
μ= mean = 84
σ=standard deviation = 5
x= random number = 89
Putting these values, we get
Now, we know that we need to find students who score greater than 89%
so P(X>89) or P(X>1),
finding value of z= 1 which can be easily found using z score tables.
By looking at table we get the value of z = 0.3413
Subtracting the value of z from 1 we get
Percentage of the students scored higher than 89% = 1-0.3413 = 0.6587 or 65.87%
<u>We have to look for the pattern in the numbers</u>, so we can figure out what the next term in the sequence is !
It looks like,<u> each number is multiplied by 2!</u>
7 × 2 = <em>14 </em>
14 × 2 = <em>28 </em>
So, what's next?
28 × 2 = ?
The next term in the geometric sequence is ... 56!
I hope I helped :)
Comment if you have any confusion !
D? I think it my solution is the close to this answer
I think it's 2.7, yes that's the answer
