Two equations can be generated from the equation above, one for Package A and the other for Package B.
(Package A) 3x + 2y = 18
(Package B) 8x + 6y = 50
Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.
Answer:
18%
Step-by-step explanation:
% increase = <u>new population - old </u><u>population</u> x <u>100</u>
old population. 1
% increase = <u>237180 - 201000</u> x <u>100</u>
201000. 1
% increase = <u>36180 x </u><u>100</u>
201000
% increase = <u>3618000</u>
201000
% increase = 18%
Answer:
Mean= 10.83
Median= 9.5
Step-by-step explanation:
Given number,
10, 15, 8, 11, 9, 12
N= 6
As we know,
Mean= Ex/N
=10+15+8+11+9+12/6
=65/6
=10.83
Therefore, Mean= 10.83
Now,
Median(MD)= (N+1/2)th item
= 6+1/2
=7/2
=3.5th item
So, Median(MD)= 3th+4th/2 item
= 8+11/2
= 19/2
= 9.5
Therefore, Median= 9.5
Answer:
y = 1/2x +4
Step-by-step explanation:
You are given the slope (m) of the line and a point, and asked for slope-intercept form:
y = mx +b . . . . . . . line with slope m and y-intercept b
The value of the intercept, b, can be found from the point by rearranging this equation to ...
b = y -mx
b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1
Then the equation of the line with m=1/2 and b=4 is ...
y = 1/2x +4
