Answer:
The third one.
Step-by-step explanation:
The square root of 81 is 9. The closest answer to that is the third one.
The answer is B, if you try searching general to standard form there's lots of useful tutorials. Wikihow is good.
It’s an isosceles triangle, so both the legs will be congruent, and then we can use the Pythagorean thrm
8^2+8^2=x^2
64+64=x^2
128=x^2 *square root both sides*
x=11.3
So the answer would be C
It is important to note that all the information's required are already given in the question
Probability that a day will be hot = 0.15 + 0.10
= 0.25
Probability that a day will be sunny = 0.15 + 0.30 + 0.10
= 0.55
Adding the above two probabilities, we get = 0.25 + 0.55
= 0.80
Now
Probability that a day will be both hot and sunny = 0.15
So
Probability that a day was hot or sunny = 0.80 - 0.15
= 0.65
I hope the procedure is clear enough for you to understand.
