J/-2+7 = -12
j/5 = -12
j/5 • 5 = -12 • 5
j = -60
#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply

Step-by-step explanation:
82% of the existing homes in 2011 are sold between $173,300 and $296,300.
<u>Step-by-step explanation</u>:
- mean sale price, M = $214,300
- standard deviation, SD = $41,000
- The sale prices are normally distributed.
The left side of the mean ⇒ 34% = M-SD, 14% = M-2SD, 2% = M-3SD
- 34% ⇒ M-SD = 214,300-41,000 = 173,300
The right side of the mean ⇒ 34% = M+SD, 14% = M+2SD, 2% = M+3SD
- 34%⇒ M+SD = 214,300+41,000 = 255,300
- 14%⇒ M+2SD = 214300+2(41,000) = 296,300
The percentage of existing homes in 2011 that sold for between $173,300 and $296,300 is 34%+34%+14% = 82%
Y-intercept is when a line intercepts/crosses over the Y axis, and initial value Is the unknown function at a given point in the domain of the solution. I hope this helped ^^
