Answer:
The sum of the probabilities of all outcomes must equal 1 . If two events have no outcomes in common, the probability that one or the other occurs is the sum of their individual probabilities. The probability that an event does not occur is 1 minus the probability that the event does occur.
Step-by-step explanation:
Answer:
x = sqrt (22)
Step-by-step explanation:
This is a RIGHT triangle with the two legs of equal length sqrt 11
us pythagorean theorem
a^2 + b^2 = c ^2 where a and b are the legs and c = hypotenuse
(sqrt11)^2 + (sqrt11)^2 = x^2
11 + 11 = x^2
x = sqrt (22)
On a basic parallelogram, opposite sides are parallel, diagonals bisect each other and, consecutive angles are supplementary. However on a parallelogram diagonals aren't congruent.
So the answer is D
Answer:
20 hours
Step-by-step explanation:
To find the answer, you first should find out how long is 25% of the original battery life, 16 hours. To find this, you can divide 16 by 4, or multiply 16 by 0.25. Either works.
16/4=4.
So the new battery lasts 4 hours more than the old battery. Then, add this to the original length to find how long the new battery will last in total.
16+4=20
Answer:
The answer to your question is letter C.
Step-by-step explanation:
A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
B. The same as letter A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
C. This option is correct, is the equation of a vertical parabola and the negative indicates that it opens downward, as in the graph.
D. This option is incorrect because the equation is of a vertical parabola that opens upward.
