Answer: He would have 100 ties
Answer:
step by step Explanation:
Since this is a right triangle,
We can find the length b by using the Pythagoras theorem
a2+b2=c2
Plugin the values
→22+b2=62
→4+b2=36
→b2=32
Take the square root of both sides
→√b2=√32
→b=√16⋅2
⇒b=4√2
Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The number of student is 
The highest amount is
$200
The lowest amount is
$75
The sample mean is
&140
The Standard deviation of this set is mathematically evaluated as

Substituting values


The margin of error (ME) is mathematically evaluated as

Where
is the critical value for
i.e the significance level
From the critical value table this is
So


Answer: P = 2716.3448786 or about 2700
Step-by-step explanation:
Answer:
21square feet
Step-by-step explanation:
Count the whole squares first.
if each square is one square foot then 18 whole squares will be 18×1= 18 square feet
add halves (aproximate halves) together. (3 in total)
Therefore A= 18 +3
= 21 square feet
