Answer:
x = 8
Step-by-step explanation:
3(x-5)+6x = 3x-15+7x
3x-15+7x = 65
10x = 80
x = 8
Answer:
za/2: Divide the confidence level by two, and look that area up in the z-table: .95 / 2 = 0.475. ...
E (margin of error): Divide the given width by 2. 6% / 2. ...
: use the given percentage. 41% = 0.41. ...
: subtract. from 1.
Answer:
R=0.25
Step-by-step explanation:
Y=RX
2=R×8
2/8=8R/8
R=0.25
To solve this problem, all you need to do is make a standard graphing equation. The first step is finding mode using two points from the table. We'll use (1, 70) and (2, 90).

From the work, we've found that the
slope of this equation is
20.
Next, we need to finish writing the equation and plug in the coordinates to solve for the y-intercept.

Now we have all the information we need to write our equation, which is:
y = 20x+50Hope this helps!
Answer:
D. 2 7/12
Step-by-step explanation:
8 1/4 - 5 2/3
Turn to improper fractions.
33/4 - 17/3
Make the denominators equal.
99/12 - 68/12
Subtract the fractions since denominators are equal.
31/12
= 2 7/12
