The answer is 96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is 96%.

Answer:
Thus, the ratio is:
a:b = 1:4
Step-by-step explanation:
Given the expression
Divide both sides by 2
Divide both sides by b
Thus, the ratio is:
a:b = 1:4
Answer:
<em>The amount of rabbit after 1 year will be </em><em>320</em><em>.</em>
Step-by-step explanation:
A gardener brought 5 rabbits, after 2 months rabbits became 10.
The growth continues on the same ratio.
This represents a geometric sequence with 1st term as 5 and common ratio as 2.
As we have to find the amount of rabbit after 1 year, so the we have to find th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.
nth term in a G.P is,
Putting the values,
