Step-by-step explanation:
The probability that Aaron goes to the gym on exactly one of the two days= pro. that he goes on Saturday or pro. that he goes on Sunday
Prob. he goes on Saturday =0.8 while prob. that he goes on Sunday but not on Saturday = 0.9.
The prob. that Aaron goes to the gym either of the two days= 0.8 + 0.9 = 1.7
Answer:
(2a-5)² is the final solution
Step-by-step explanation:
4a²-20a+25
= (2a)² - 2 × 2a × 5 + 5²
= (2a-5)²
Answer:
4 runners
Step-by-step explanation:
I divided 1/4 by 1/16 and got 4 as an answer.
Hope this helps :)
(Correct me if i am wrong)
a²+b² = c² where a and b are legs and c is the hypotenuse
So...
a²+4²=13²
a²+16=169
a²=153
a=√153
answer: approx. 12.37 units
Answer:
S={(heart), (diamond), (club), (spade)}
Step-by-step explanation:
In probability, a set is a well-defined collection of objects, product of an independent successful operation.
A sample space is the combination of all possible outcomes in an operation, so in this case, when we select one card and record the denomination, then we need to check what characteristic from the card are we looking for, from the problem we can see that is the denomination by itself, not the color, the number of the card, or anything else, and we only have 4 options of denomination so the sample space would be:
S={(heart), (diamond), (club), (spade)}
