Chips Defective Chips

Al chips 4 %

Total production per day 50.999 4 %

Randon sample sold 100 4 %

% defectives should be = % total production

Defectives expected in sample is 4% of 100 = 4 x 100 / 100 = 4

Chance of 2 defective chips 1

If g(x)=3x-11, what is x is g(x)=289
Liula [17]

Answer:x=100

Step-by-step explanation:

Since you know that g(x)=3x-11 all you have to do is substitute that into g(x)=289. So you get 3x-11=289. To get x you have to add 11 on both sides.

3x-11=289

+11 +11

----------------

3x = 300

Divide 3 on both sides to get x by itself

3x =300

---- -------

3 3

x=100

The length of a rectangle is 7 ft longer than twice the width. If the perimeter is 92 ft find the length and width of the rectan
user100 [1]

Width of the rectangle is 13 ft and length of the rectangle is 33 ft

<u>Step-by-step explanation:</u>

Step 1:

Given perimeter of the rectangle = 92 ft. Let the width be x, then the length of the rectangle = 2x + 7. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.

92 = 2(2x + 7 + x) = 2(3x + 7) = 6x + 14

⇒ 92 = 6x + 14

⇒ 78 = 6x

⇒ x = 78/6

∴ x = 13 ft

⇒ Width of the rectangle = 13 ft

∴ Length of the rectangle = 2x + 7 = 26 + 7 = 33 ft

Complete equation describing how X and Y are related.
den301095 [7]

Answer:

2

Step-by-step explanation:

Every time the x-value increases by 1, the y-value increases by 2. Therefore, the slope of the line must be equal to 2/1=\boxed{2} (rise/y-values over run/x-values). In slope-intercept form y=mx+b, m represents the slope of the line, b represents the y-intercept, and (x,y) represents any point the line passes through.

Since m represents the slope of the line, the value of

While the question only asks for this value, it's good to note that the equation of the function is y=2x+7 (find 7 by substituting any ordered pair in the table with m=2).
