The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 54 ounces and a standard deviation of 11 ounces. Use the Standard Deviation Rule, also known as the Empirical Rule. Suggestion: sketch the distribution in order to answer these questions. i&ii) 99.7% of the widget weights lie between and
iii) What percentage of the widget weights lie between 43 and 87 ounces? % (answer as a whole number)
iv) What percentage of the widget weights lie below 76 ? % (answer as a whole number)

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

dude thats to long figure it

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the first one

step-by-step explanation:

just id the test.
