Answer:
P(-2,8) Q(-8,8) R(-8,2) S(-2,2)
Step-by-step explanation: 180 degree rotation rule = (x,y) ---- (-x,-y)
ex : point B (-2, 7) will be B' (2, -7)
You must begin by isolating the x.
1. add -35 to the other side of the equation
2. divide by 8 to get x by itself
Hope this helps!
Answer:
d < 27
Step-by-step explanation:
Solve for d by subtracting 8 from both sides. This isolates d:
d + 8 < 35
-8 -8
------- -------
d < 27
Answer:
The answer is 4
Step-by-step explanation:
2x + 5 = 13
Now, Subtract 5 from both side we get,
2x + 5 - 5 = 13 - 5
2x = 8
Then, Divide both side by 2 we get,
2x/2 = 8/2
x = 4
Thus, The answer is 4

Answer:
There is a probability of P=0.94 that at least 81 rolls are needed to get the sum of 307.
Step-by-step explanation:
The roll of a six-sided die sum has this parameters:
Mean: 3.5
Standard deviation: 1.7
If the die is rolled 81 times, the distribution of the sum of the 81 rolls will have the following parameters:

Note: the variance of the sum of random variables is equal to the sum of the variance of the individual variables.
Then, we can calculate the probabilties that the sum of 81 rolls is lower than 307.

There is 94% of chances that the sum of 81 rolls is lower than 307, so there is a probability of P=0.94 that at least 81 rolls are needed to get the sum of 307.
