Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..
d^2=x^2+y^2
d^2=2^2+2^2
d^2=4+4
d^2=2*4
d=√(2*4)
d=2√2 mi (exact)
d≈2.83 mi (to nearest hundredth of a mile)
The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
Answer:
Step-by-step explanation:
Set ratios and solve for x
<u>Corresponding sides are AC with A'C' and CB with C'B'</u>
- AC/A'C' = CB/C'B'
- (x - 1)/2 = (x + 4)/3
- 3(x - 1) = 2(x + 4)
- 3x - 3 = 2x + 8
- 3x - 2x = 8 + 3
- x = 11
<u>Find the values of AC and CB:</u>
- AC = x - 1 = 11 - 1 = 10 cm
- CB = x + 4 = 11 + 4 = 15 cm
Answer:
Polynomial is the degree of the highest degree of polynomial form.
Number
0
is also called a polynomial and it has no degree
The ending balance after the transactions is; $59.25
<h3>How
to determine ending balance</h3>
To determine the ending balance after a number of transactions;
- Let money inflow and balance be represented as positive.
- Let money outflow be represented as negative.
Therefore; Since starting balance is; $822.67; we have;
- <em>$822.67 + $227.45 - $600.00 + $50 - $100 - $200 - $3.50 - $2.50 - $134.87.</em>
The ending balance on the account is therefore; $59.25
