Answer:
The weight of green beans in each jar is 1/16 pounds
Step-by-step explanation:
Total weight of beads = 3/4 pounds
Weight of pink beads = 1/6 × 3/4 pounds = 1/8 pounds
Weight of green beads = 3/4 - 1/8 = 5/8 pounds
Total weight of green beads in 10 jars = 5/8 pounds
Weight of green beads in each jar = 5/8 ÷ 10 = 5/8 × 1/10 = 1/16 pounds
30% = .3
120 x .3 = 40
120 + 40 = 160

Answer:

But we need to calculate the mean with the following formula:

And replacing we got:

And for the sample variance we have:

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance 

Step-by-step explanation:
For this case we have the following data:
1.04,1.00,1.13,1.08,1.11
And in order to estimate the population variance we can use the sample variance formula:

But we need to calculate the mean with the following formula:

And replacing we got:

And for the sample variance we have:

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance 

Answer: X=1.5
Step-by-step explanation:
The equation when y is -16
-16=-8x-4
-12=-8x
12/8 is 1.5
(-6)(1)∧⁽2/-7⁾= -6 is the answer
Hope it's right
