Since q(x) is inside p(x), find the x-value that results in q(x) = 1/4
so we conclude that
therefore
plug
into p( q(x) ) to get answer
Answer:
about 25
Step-by-step explanation:
102.02 ÷ 4.011?
I will round 102.02 to 100
I will round 4.011 to 4
100/4 is 25
My estimates of 102.02 ÷ 4.011 is about 25
Answer:
We can say that the no.s are X and form the following equation:
X × (X + 2) = 440
2x = 440-2=438
x = 438/2
x= 219
x+2=219+2= 221
Answer:
30.91% probability that he makes exactly three of his next four free throws
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either he makes ir, or he does not. The probability of making a free throw is independent of other free throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Makes 56% of free throws.
So
Assuming free throws are independent, the probability that he makes exactly three of his next four free throws is:
This is P(X = 3) when n = 4. So
30.91% probability that he makes exactly three of his next four free throws
-5x + y = 5 . . . . . (1)
-4x + 2y = 2 . . . . (2)
(1) x 2 => -10x + 2y = 10 . . . (3)
(2) - (1) => 6x = -10 => x = -8/6 = -4/3
From (1), -5(-4/3) + y = 5 => y = 5 - 20/3 = -5/3
Therefore, x = -4/3; y = -5/3
