Answer:
(x, y) = (20, 449)
Step-by-step explanation:
When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...
21.95x +10 = 22.45x
10 = 0.50x . . . . . subtract 21.95x
20 = x . . . . . . . . .multiply by 2
y = 22.45x = 22.45·20 = 449
Answer:
See below in bold.
Step-by-step explanation:
There are 2 even and 6 odd numbers in the list.
A.
Prob(Picking an odd number) = number of odd numbers / total of numbers
= 6/8 = 0.75.
Prob(Picking a 10) = 1/8 = 0.125.
Answer = 0.75 * 0.125 = 0.09375
= 0.094 to 3 dec. places.
B.
Prob( Picking and even) = 2/8 = 1/4.
Prob( Picking another even without replacement) = 1/7.
Answer = 1/4 * 1/7 = 1/28
= 0.036 to 3 dec. places.
C.
There are 5 numbers greater than 4.
Prob(Picking a number > 4) = 5/8.
Prob( Picking a 1 without replacement) = 1/7.
Answer = 5/8 * 1/7
= 5/56
= 0.089 to 3 dec. places.
Answer:

Answer:

Step-by-step explanation:
we have

Subtract 3x both sides


Adds 3 both sides


Divide by -4 both sides

therefore
The missing step is
