The answer is D, about 8.5 miles. You can use the Pythagorean theorem
and plug in 3 and 8 as the length of the legs.
Answer:
The probability is 0.17
Step-by-step explanation:
In this question, we are asked to calculate the probability that Sheryl makes a free throw and Tess not making a free throw
To answer this question, we must remember that the probability of an event happening and that same event not happening is 1. This will guide us to answer this question.
The probability of Sheryl making a free throw is 0.25
The probability of Tess making a free throw is 0.32, his probability of not making a free throw will be 1-0.32 = 0.68
Now we calculate the probability asked in the question as;
Probability of Sheryl making a free throw * probability of Tess not making a free throw
= 0.25 * 0.68 = 0.17
To find whether 1/2 is greater than 1/3, it is important to convert them to decimals. By converting them to decimals, we can visually understand the number that is greater.
1/2 = 0.5
1/3 = 0.33
So from the above deduction we can conclude that 1/2 is greater than 1/3. I hope the procedure is not that complicated for you to understand. You can always use this procedure for finding the answer to similar kind of questions in future without requiring any help from anyone else.
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
1.25 is the slope 5/4 rise over run
