Answer:
And we can find this probability with this difference and using the normal standard distribution
Step-by-step explanation:
Let X the random variable that represent the amount of Jen monthly phone of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And we can use the z score formula given by:
Replacing the info we got:
And we can find this probability with this difference and using the normal standard distribution
the question does not present the options, but this
does not interfere with the resolution
Let
x--------> the number of color copies
y-------> the number of black-and-white copies
we know that
x+y=6--------> equation 1
3x+y <=12------> equation 2
using a graph tool
see the attached figure
the solution is the triangular shaded region
I decided to simply both equations:
75/4 *3 225/12
19/6 *2 38/12
First is to find a common factor which is 12, multiply both sides.
divide 38/225 and you should get 5.92.

Answer: 60 square units
Step-by-step explanation:
If you're supposed to find area it would be 5x7 + 5x5 = 35 + 25 = 60
