A manufacturing process produces bags of cookies. The distribution of content weights of these bags is Normal with mean 15.0 oz
NeTakaya

Answer:

100 bags

Step-by-step explanation:

S.E = σ/ √n

0.1 = 1 / √n

Square both sides

0.1² = 1² / n

0.01 = 1 / n

0.01n = 1

n = 1 / 0.01

n = 100

I watched a video and didn't get my free answer, can I have some help,
vazorg [7]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b,

where m = slope, and b = y-intercept.

From the slope-intercept equation y = 5x - 3, we see that the slope of the line is 3.

The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

where m = slope, and (x1, y1) is a point on the line.

We have point (-2, -13), so x1 = -2, and y1 = -13.

We also have slope 5, so m = 5.

Now we use the coordinates of the given point and the slope in the point-slope equation.

y - (-13) = 5(x - (-2))

We simplify to get

y + 13 = 5(x + 2)

Which of the following numbers is the smallest 0.008 or 1/3 or 0.048 or 0.36 or 1/9
RideAnS [48]

Answer:

The smallest number is 0.008

Step-by-step explanation:

To find out which number is the smallest we convert the decimals to percentages

That's

0.008 × 100= 0.8%

1/3 × 100 = 33.3%

0.048 × 100 = 4.8%

0.36 × 100 = 36%

1/9 × 100 = 11.1%

Comparing from the above percentages the smallest one is 0.8% which is

0.008.

Hope this helps you.
