Answer:
Step-by-step explanation:
If 70% passed both, then that means 30% passed either one test, or neither test.
Since 80% passed the first test, we know that 20% of the students failed the first test.
This means that the other 10% of the students came from the 80% that already passed the first test.
These make up 10/80 = 12.5% of the people that passed the first test, meaning your answer is 100-12.5=87.5%
Use trigonometry to find L.
Tangent = opposite over adjacent on any right triangle.
tan(L) = 18/23
Take the inverse on both sides.
arctan(tan(L)) = arctan(18/23)
L = 38.0470425318
L = 38.05°
Done.
<span>Given the table below where Low represents the fewest
points scored and High represents the highest points scored by a single
team member.
PART A:
The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.
A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.
From the table, it can be seen that Team C has the least standard deviation.
Therefore, </span><span>If
the club wants to award the team that has the most consistent scoring
among its team members,
team C should be chosen.
PART B
The mean and the median is a measure of center of a data set.
The mean describes the average of a data set.
From the table, it can be seen that Team B has the highest average score.
Therefore, </span><span>If the club wants to award the team with the highest average score,
team B should be chosen.</span>

Answer:
221
Step-by-step explanation:
Given sequence is ,
> 5 , 6 , 7 , 8 , 9.
The common difference is 6-5 = 1 .
Therefore , the 221st number will be
> 221 st term = 221 × 1 = 221 .
<u>Hence</u><u> the</u><u> </u><u>2</u><u>2</u><u>1</u><u> </u><u>st </u><u>term </u><u>is </u><u>2</u><u>2</u><u>1</u><u> </u><u>.</u>
