Answer:
So, we will be using point-slope form to construct this equation.
Point-slope form's general formula is as follows:
Y - Y1 = m( X - X1)
M is the slope,
Y₁ is the Y-coordinate of the point
X₁ is the X- coordinate of the point.
So, our slope is 3 (since the equation is given in slope-intercept form)
Our Y₁ is 7 and out X₁ is 4
So, now we just plug our numbers into the equation.
There's your equation.
Y - 7 = 3( X - 4).
Hope this helps!
Answer:
1.44
Step-by-step explanation:
No. of warp coils manufactured in one group = 36
defect rate = 4%
That is 4 out of every 100 warp coil is defective
No. of defective warp coil in one group = 4% of warp coil in one group
= 4% of 36 =4/100 *36
= 1.44
Thus, there are 1.44 defective coil in each group.
Since, mean number is average number of defect.
So if each group has 1.44 defective coils then mean for all the group will remain same i.e 1.44

Answer:
25 = total number of paintbrushes
Step-by-step explanation:
number with yellow handles = total number of paintbrushes * percent with yellow handles
We know that 15 have yellow handles and the percent with yellow handles is 60
15 = total number of paintbrushes * 60%
We need to change the percent to a decimal
15 = total number of paintbrushes * .60
Divide each side by .60
15/.60 = total number of paintbrushes * .60/.60
25 = total number of paintbrushes
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.
