Answer: It's D.) factor
Step-by-step explanation: You factor both numerator and denominator
Answer:
the slope is 2
step-by-step explanation:
slope = rise/run
you can calculate it with the numbers without the graph like so
m = y2 - y1 / x2 - x1
(-3, -2) (1, 6)
(x1, y1) (x2, y2)
m = 6 + 2 / 1 + 3
m = 8 / 4
m = 2
<span>Because the question asks for the sample standard deviation, use this formula:
s = square root of (sum of x - xBar)² / (n - 1)
There are 9 numbers, there, so n - 1 = 8
Next, find the mean (xBar): 15 + 42 + 53 + . . . + 47 = 227. 227 / 9 = ~25.2
Next, for each number, subtract xBar and square the result, like this:
(15 - 25.2)² = 104.0
(42 - 25.2)² = 282.2
(53 - 25.2)² = 772.8
...
Next, add up all those values (i.e., 104 + 282.2 + 772.8...) and divide by (n - 1).
In this example, the answer to this is 2,535.2 / 8, or 316.9.
Finally, take the square root of that number to get s.
sqrt (316.9) = 17.8.
Therefore, the answer is 17.8.</span>
Answer:
1. 0.2222222
2. .6667
Step-by-step explanation:
for question 1
there can only be 36 outcomes so you find out how many time you could get 7and2 which is 8 from so u write 8.36=.2222
for question 2
divide the outcome by the total out comes example(there are 6 red balls and 4 white out of 15 so you do 10/15=.6667)
Well, 2/3 multiplied by 5 would be, 3.33
