Answer:
The coordinates of B are (-8,25).
Step-by-step explanation:
Consider the completer question is " M(−2, 10) is the midpoint of AB. If A has coordinates (4, −5), what are the coordinates of B".
Let coordinates of B are (a,b).
Formula for midpoint:
Midpoint of A and B is
It is given that M(−2, 10) is the midpoint of AB.
On comparing both sides we get
Multiply both sides by 2.
Subtract 4 from both sides.
The value of a is 8.
Similarly,
Multiply both sides by 2.
Add 5 on both sides.
Therefore, the coordinates of B are (-8,25).
The square root of (5^2) is 5. {(5^2)=25} {square root 25 is 5}.
The square root of -5^2 is also 5. {(-5^2)=25} {square root 25 is 5}.
Hope this helps!

Answer:
B) 0.02
Step-by-step explanation:
<u>Use the Binomial Theorem</u>
We have the probability of success, , and the probability of failure, . The binomial coefficient, , represents the amount of possible combinations that items can be chosen out of items, with its respective formula .
Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02
