Answer:
4 4√3
Step-by-step explanation:
Answer:
Here, we have:
P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084
P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238
P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385
P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272
Add up those above, then the probability that it will snow AT LEAST five of those days in February:
P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979
Hope this helps!

Answer: 10.2
Step-by-step explanation:
Area of a circle is
A= pixr^2
327= 3.14r^2
Divide by 3.14
= 104.14
Get the sq rat of 104.14
= 10.2
90÷17= 5.29 i think but not sure
To find the answer, use pythagorean theorum (a^2 + b^2 = c^2)
We'll square a and c, and then subtract a from c.
9 + b^2 = 361
361 - 9 = 352
The square root of 352 is 18.7
18.7 should be the correct answer.
