QUICK ANSWER
A quadrilateral with exactly one pair of opposite parallel sides is called a trapezoid. As with all quadrilaterals, the sum of the interior angles of a trapezoid is always equal to 360 degrees
Answer:
I believe it is .0801
Step-by-step explanation:
- A negative exponent will always turn into a fraction
- First change it to a fraction
1/10^2
- Simplify the exponent
10 times 10 = 100
- Change the fraction
1/100 or in decimal form which is 0.01
- Now the addition
8 + 0.01 = <u>8.01</u>
- Move decimal to two decimal places
.0801
Answer:
Total number of way to pick 3 letters is 6C3 = 20.
Step-by-step explanation:
P(E) = 3/6 = 1/2
P(O) = 3/6 = 1/2
The intersection is P(E n O) = P(E)P(O | E)
= 1/2(2/5)
= 1/5
P( E or O but not both) = P(E and not O) + P(O and not E)
(THis step is easier to understand if you shade in a venn diagram for this):
= [ P(E) - P(E n O) ] + [ P(O) - P(O n E) ]
= 1/2 - 1/5 + 1/2 - 1/5
= 1 - 2/5
= 3/5
The P (E or O or both ) is just the union of the two:
P( E U O) = P(E) + P(O) - P(E n O)
= 1/2 + 1/2 - 1/5
= 4/5
I'll just make a manual computation on how 1 member recruits his members until week 5. Then multiply the sum by 2.
old new
1: 1
2: 1 x 3 = 3 ⇒ 1 3 *only new members recruit 3 more
3: 3 x 3 = 9 ⇒ 4 9
4: 9 x 3 = 27⇒ 13 27
5: 27 x 3 = 81 ⇒ 40 81
40 + 81 = 121. Total number of members under 1 founding member.
121 x 2 founding members = 242 total number of members within 5 weeks.
22.9 is the closest but not exact. It was probably rounded off.
I used the formula: leg^2+leg^2=hypotenuse^2
(You can use that formula for any right triangle.)
