The answer is x=19.
Hope it helps! (:
Step-by-step explanation:
6A = B
100+A = C
A + B + C = 692
just replace B and C with A values
A + (6A) + (100 + A) = 692
8A = 592
A = 74
take A and put back into original relationships to find other numbers.
6A = B
6(74) = 444
100 + A = C
100 + (74) = 174
74 + 444 + 174 = 692

Answer:
Step-by-step explanation:
Easiest way would be to substitute points into the given equations and plot your answers.
E.g. if you substitute points into your first equation you get:
If x = 0, y = -4(0) +2 = 2
If x = 1, y = -4(1) +2 = -2
If x = -1, y = -4(-1) +2 = 6
Etc.
Second equation:
If x = 0, y= -(0) -1 = -1
If x = 1, y = -1 -1 = -2
If x = -1, y = -(-1) -1 = 0
Pretty much just plug in values for x into the equations to find y.
Once you have your points, draw a line :)
Where the two lines intercept would be the solution.
To find the critical value
that corresponds<span> to 97% confidence level</span>:
Step 1:
Subtract 0.97 from 1:
1 - 0.97 = 0.03
Step 2:
Divide 0.03 by 2:
0.03 / 2 = 0.015
Step 3:
Subtract 0.03 from 1:
1 - 0.015 = 0.985
Step 4:
From the normal distribution table, the z score that corresponds to a probability of 0.985 is 2.17.
Therefore, <span>the critical value that corresponds to 97% confidence level is 2.17.</span>
