According to the empirical rule, approximately 68% of data fall within 1 standard deviation of the mean.
Answer:
give me 5 mins and I will tell you the answer
It produces 500 per hour and those are divided into 50 piece bundles. so if we divide by 50 we will see how many bundles.
500/50 = 10.
it says that he does 10 bundles an hour and we found it makes 10 bundles per hour so it will take him the exact amount of hours that they run to load.the bundles.
it runs 3 shifts that are 4 hours. so to get the hours we can multiply 3 shifts by 4 hours
3 * 4 = 12 hours
if it did not.match we.could have kept going like this
so 10 bundles per hour for 12 hours is
10 * 12 = 120 bundles
he runs 10 bundles in an hour so we can divide the total by the amount per hour and gwr.how long it takes
120 / 10 = 12 hours
Answer:
so 2a+3b=±13
Step-by-step explanation:
4a²+9b²=97
ab=6
2a+3b=?
by using formula
(a+b)²=a²+b²+2ab
(2a+3b)²=(2a)²+(3b)²+2(2a)(3b)
(2a+3b)²=4a²+9b²+12ab
putting values
(2a+3b)²=97+12(6)
(2a+3b)²=97+72
(2a+3b)²=169
taking square root on both sides
√(2a+3b)²=√169
2a+3b=±13
i hope it will help you
