For this case we have the following equation:
Where,
n: number of invitations:
c: cost in dollars
We note that the slope of the line for this case is:
The slope represents the cost of printing each of the invitations.
Therefore, it is false that the cost of printing each invitation is $ 5.50
Answer:
the following is not true:
A) each invitation costs $ 5.50 to print.
I hope this helped you! Good luck!
To find the x-intercept, set y=0 and solve for x.
To find the y-intercept, set x=0 and solve for y.
7x+6y=21
x-int: y=0
7x+6(0)=21
7x=21
x=3
y-int: x=0
7(0)+6y=21
6y=21
y=21/6 or 7/2

Answer: 103</h3>
Explanation:
The term "bisect" means "divide in half", or "divide in two equal pieces".
Angles A = 58 and B = 96 divide in half to get 29 and 48 respectively
Find their sum and subtract it from 180 to get angle AMB
29+48 = 77
180-77 = 103

b) 6.68%
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean score on the scale is 50. The distribution has a standard deviation of 10.
This means that 
Matthew scores a 65. What percentage of people could be expected to score the same as Matthew or higher on this scale?
The proportion is 1 subtracted by the p-value of Z when X = 65. So



has a p-value of 0.9332.
1 - 0.9332 = 0.0668
0.0668*100% = 6.68%
So the correct answer is given by option b.
