Answer:
a) 54 mph to 144 mph
Step-by-step explanation:
We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
At least eight-ninths of the player's serves.
8/9 is approximately 89%
So
Mean: 99, standard deviation: 15
99 - 3*15 = 54
99 + 3*15 = 144
So the correct answer is:
a) 54 mph to 144 mph
I got 6 units^2. So the answer is the second choice. ab/2 = 3*4/2 = 6.
Hello!
Throughout this problem, we will add or subtract values from our original balance.
In your checkbook, there was 298.72 dollars, and then you deposited 425.69 dollars. The function you would do is addition.
$298.72 + 425.69 = $724.41
If you wrote a check, then the amount you wrote is removed from your checkbook.
$724.41 - $29.72 - $135.47- $208.28 = $350.94
Then, the bank deducted 5 dollars from your account.
$350.94 - $5.00 = $345.94
This leaves you with $345.94 at the end of the week.
Therefore, your answer is choice C, $345.94.
Z-m=z+bx
z-m-z=z+bx-z
-m=bx
bx=-m
bx/b=-m/b; b=0
x=-m/b; b=0
A fraction that is less than 5/6 and has a denominator of 8 would be 4/8 because if you compare 4/8 and 5/6 4/8 is less than 5/6. (to compare this two fractions you need to make them have the same denominator so they would end up been 4/8=12/24
5/6=20/24
And 12/24 is smaller than 20/24
(Besides 4/8 is half and 5/6 is more than half
