Answer:
P = 0.23375
Step-by-step explanation:
given,
you remain in store for 15 minutes.
you friend remains in store for 10 minutes.
probability that they are store at the same time
from the graph attached below
shaded region shows the required probability,.
probability of the square = 1
probability of the shaded region = 1 - (area of lower triangle - area of upper triangle)
area of lower triangle = \dfrac{1}{2}(0.85)(0.85)
= 0.36125
area of the upper triangle = \dfrac{1}{2}(0.9)(0.9)
= 0.405
probability of the shaded region = 1 - (0.36125+0.405)
= 0.23375
Answer:
-20x -27 is the required expression.
Step-by-step explanation:
whenever we are to solve the system of equations by substitution method we have to write one variable in the form of other so as to get the value of unknowns
here, we are given two expressions:
And
We have to substitute x in terms of y because the equation should be equivalent to y we will put in
we will get:
is the expression we will get after expression equivalent to y.
Answer: 92/3 OR 30 2/3 ??
Step-by-step explanation:
Answer:
36666.66 units
Step-by-step explanation:
Let the cost of computer 1 is 3x and that of 2 is 2x.
Cost of first computer = 3x
55000 = 3x
x = 18333.33
Cost of second computer = 2x
= 2(18333.33)
= 36666.66
Henc, the cost of the second computer is 36666.66 units.
