The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped with a mean of 40 ounces and a standard deviation of 10 ounces. Using the Empirical Rule, answer the following questions. Suggestion: Sketch the distribution. a. 95% of the widget weights lie between
b. What percentage of the widget weights lie between 30 and 63 ounces?
c. What percentage of the widget weights lie above 8%?

good luck on your studies! : )

yes

step-by-step explanation:

yes

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
