A sample of 100 cans of peas showed an average weight of 14 ounces with a standard deviation of 0.7 ounces. If the distribution
Roman55 [17]
This is an example of a normal distribution. An average weight is 14 ounces and a standard deviation is 0.7 ounces.
14.7 = 14 + 0.7 = Average + 1 Standard Deviation.
It means that the percent of cans that will weigh over 14.7 ounces is:
100% - ( 50 % + 34 % ) = 100% - 84% = 16%
16% of 100 cans:  16/100 * 100 = 16.
Answer: 16 cans.

Pls help I will give you a crown pls 13 points

Option C: y = \frac{1}{2}x+\frac{5}{2} is the right answer

Step-by-step explanation:

Given points are:

(x1,y1) = (-1,2)

(x2,y2) = (3,4)

First of all, the slope has to be found

m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{4-2}{3+1}\\= \frac{2}{4}\\=\frac{1}{2}

The slope-intercept form of line is:

y = mx+b

Putting the value of m

y = \frac{1}{2}x+b

Putting (3,4) in equation

4 = \frac{1}{2}(3) +b\\4 = \frac{3}{2} +b\\b = 4 - \frac{3}{2}\\= \frac{8-3}{2}\\=\frac{5}{2}

Putting the value of b

y = \frac{1}{2}x+\frac{5}{2}

Hence,

Option C: y = \frac{1}{2}x+\frac{5}{2} is the right answer

elixir [45]

(x/2 - 3) - (4x^2 + x - 4)

(x/2 - 3) - (16x + x - 4)

(1/2x - 3) - (17x - 4)

-16.5x - 1


I believe that is the correct answer.
