A. Y= -7
X=2
4x+2y=-6
+(3x-2y=-8
Hello,
I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!
1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.
2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.
3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.
4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!

Hope I Helped!
Have a fantastic Day!
Hello,
It is true that the sequence is arithmetic. Its common difference, of subtracting 7 each time, is always going to subtract 7 from each number.
Hope this helps!

Answer:
Probability = 0.1587
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ test for adults that is normally distributed with mean 
= 100 and standard deviation 
= 15.
Also, US military has minimum IQ score of 85.
Thus, the probability that randomly selected adult does not meet US military enlistment standards is: 
The probability can also be written as:
Thus,
Using the Normal probability table probability of Z = -1 is 0.1587
Thus, the required probability is 0.1587
