Answer:
B. y = 
+ 6
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
First, you subtract 500 from 4,700:
4700
- 500
4200
Then you divide 4,200 by the cost per person:
4200/35
Last, 4,200/35 equals:
<h2>120</h2>
Sample = 75 printers, Printers used by small businesses = 15
p(15) = 15/75 = 0.2
At 90% limit, Z =1.64
Limit of proportion of printers used by small business = p +/- Z Sqrt [p(1-p)/n]
=0.2 +/- 1.64 * Sqrt [0.2(1-0.2)/75] = 0.2 +/- 0.0757
Limit of proportion => (0.2-0.0757) to (0.2+0.0757) => 0.1243 to 0.2757 or 12.43% to 27.57%
Let’s find X first! Let’s use the vertical angle theorem to move 67 over. Now 3x+7=67 let’s solve. We get X=20
Let’s find y!
We know that 67 and y will add up to 180 because straight lines are 180 degrees. Let’s do y+67=180 let’s solve! We get y=113
