The domain is all of the x values which are the first number in each set of parentheses and the range is all of the y values therefore domain = {2, 1, 5, 3} and range= {2, -7, 3, 0}
Answer: C) 0.8664.
Step-by-step explanation:
Given, The tread life of tires mounted on light-duty trucks follows the normal probability distribution with 
.
Let 
be the sample mean tire life of any 4 tires.
Now , the probability that the mean tire life of these four tires is between 57,000 and 63,000 miles will be :-
For Very likely , the probability should lie between 0.95 and 1.
Hence, the correct answer is C) 0.8664.
The answer is 7√3 and I'll tell you why
So the first step is to break down these big numbers to find a commen number like this:
√75= 5√3
√12= 2√3
Next you will just simply add the similar elements together:
5√3 + 2√3
5+2= 7
and so 7√3 is the correct answer
Answer:
Each of her friends ate 7/32 of the cake.
Step-by-step explanation:
Given that Fon baked a cake and ate 1/8 of it, and then she shared the remaining cake equally to her 4 friends, to determine what fraction of the whole cake did each of her friends received, the following calculation must be performed:
(8 - 1/8) / 4 = X
(7/8) / 4 = X
(28/32) / 4 = X
7/32 = X
Thus, each of her friends ate 7/32 of the cake.
