Given:
The given function is:
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
We know that the square root is defined for non negative values. So,
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, 
is in the domain of the given function.
Therefore, the correct option is A.
3/5 = 0.6
0.15 = 3/20
7/8 = 0.875
0.725 = 29/40
Answer:
38, 1
Step-by-step explanation:
Since this is a transversal, we know that 3x + 2x -10 is equal to 180. Therefore:
3x + 2x - 10 = 180
5x - 10 = 180
5x = 190
x = 38
We know that 12x + 8 is equal to 4x + 16 because they are corresponding angles. So:
12x + 8 = 4x + 16 (subtract 4x, and subtract 8)
8x = 8
x = 1
You have to do 4x4 and you will get 16in2 but out the 2 in the corner of inches that your area
Answer:
0.875
Step-by-step explanation:
Let the probability that Billy passes test 1 be P(A)
Let the probability that Billy passes test 2 be P(B)
P(A n B) = 0.7
P(A) = P(B)
Let them both be numerically x.
P(A) = P(B) = x
P(A') = P(B') = (1 - x)
Probability that he passes at least one test = 0.9
But (probability that he passes at least 1 test) = 1 - (Probabilty that he fails both tests)
Probability that he fails both tests = 1 - 0.9 = 0.1
P(A' n B')= 0.1
P(U) = P(A) - P(A n B) + P(B) - P(A n B) + P(A n B) + P(A' n B') = 1
x - 0.7 + x - 0.7 + 0.7 + 0.1 = 1
2x = 1 + 0.7 - 0.1 = 1.6
x = 0.8
P(A) = P(B) = 0.8
The conditional probability of Billy passing test 2 given the event that he passes test 1 = P(B|A) = P(A n B)/P(A) = (0.7/0.8)
P(B|A) = 0.875
Hope this helps!!!
