Multiply untegers and divide integers?
Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m =
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m = = =
Repeat with another 2 points and equate to
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m = , then
= ( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11
Answer:
13 < y + x < 32
Step-by-step explanation:
x in (8,10) and y in (5,22) implies x + y in (8+5,10+22) = (13,32) so 13 < y + x < 32.
Answer:
Step-by-step explanation:
to find the limit:
we need to first rationalize our expression.
Now this is our simplified expression, we can use our limit now.
Limit exists and it is 14 at (0,0)
Answer: 0.128
Step-by-step explanation:
The geometric probability of getting success on nth trial is given by :-
Given : The probability that he is successful on a given trial.
Then , the probability that the third hole drilled is the first to yield a productive well is given by :-
Hence, the probability that the third hole drilled is the first to yield a productive well = 0.128
