Answer:
Step-by-step explanation:
Graph both equations
The solutions are the coordinates of the intetsection point between the lines.
The coordinates of the intersection point are approximatively (-0.23,-5.12)
So:
● x = -0.23
● y = -5.12
We need to find the probability of atleast one failure in 5 trails
Probability of success = 30% = 3/10
The opposite meaning of atleast one failure is all success (no failures)
Probability of (atleast one failure ) = 1- Probability ( success)
First we find probability of success
Formula for binomial distribution
All success so n=5, r=5, p= 3/10, q= 1-p = 7/10
Probability (success) =
=
Probability (atleat one failure) = 1 -
= 0.92224
= 92.2%
Answer:
CONGRATS!!!!!
Step-by-step explanation:
Answer:
Step-by-step explanation:
a. 16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:
(4bc^6 - .5)(4bc^6 + .5)
b. 81x^6y^2-0.36a^2
is the difference of two squares, just like (a) (above); its factors are:
(9x^3y - 0.6a)(9x^3y + 0.6a)
Answer:
1&2 are true
Step-by-step explanation:
if the two lines are equidistant from each other then they must be parallel
since the lines are perpendicular
they form only right angles
