The rutter nursery company packages their pine bark mulch in 50-pound bags. from a long history, the production department reports that the distribution of the bag weights follows the normal distribution and the standard deviation of this processis 3 pounds per bag. at the end of each day, jeff rutter, the production manager, weighs 10 bags and computes the mean weight of the sample. below are the weights of 10 bags from today's production.
45.6 47.7 47.6 46.3 46.2 47.4 49.2 55.8 47.5 48.5
a. can mr. rutter conclude that the mean weight of the bags is less than 50 pounds? use the .01 significance level.
b. in a brief report, tell why mr. rutter can use the z distribution as the test statistic.
c. compute the p-value.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
