Let number of one rupee coins be x
Let number of two rupee coins be 2x
=> 2x+x=30
=>3x=30
=> x = 10
Hence , number of one rupee coints are x = 10
Number of 2 rupee coins are 2x = 2(10) = 20
Hope this helps you dear:)
Have a good day!
Answer:
c. 0.810
Step-by-step explanation:
Given, total % of satisfactory packages = 90% = 0.90
Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)
Hence, Probability of selecting two packages that re satisfactory
P(Selecting 2 satisfactory packages) = (0.90)^2
P(Selecting 2 satisfactory packages) = 0.90*0.90
P(Selecting 2 satisfactory packages) = 0.810
Note: We are selecting product since the chance of selecting in each trials are independent.

Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
Parallel lines have the same slope.
We have the equation in the slope-intercept form (y = mx + b)
Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):
