Dmitrij [34]

Answer:

a. Mean = 155.1 grams

b. Standard deviation = 0.37

c. Fractional uncertainty = 0.074

Step-by-step explanation:

a. Average weight

This is same as the mean weight;

Mathematically, that would be; sum of the weights/ the number of weights

= (155.1 + 154.8 + 155.5 + 155.3 + 154.6)/5 = 775.3/5 = 155.06 which is approximately 155.1

b. Standard deviation

Mathematically; we calculate that using the formula;

√{(x-mean)^2/(N-1)}

Please check attachment for for the complete breakdown of this

c. Fractional uncertainty

= Standard deviation/number of measurements = 0.37/5 = 0.074

Can somebody help with this problem?
Anastasy [175]

Answer:

x=-5 or -5

Step-by-step explanation:

x - 4 = 2x + 1

Subtract x from both sides canceling out the x on the left, getting...

-4 = x + 1

Then subtract the 1 from both sides canceling out the 1 on the right, getting...

-5 = x

Subtracting x from 2x gets you 1x which you just write as x because there is only one x. Doing the equation from the other side will still get you the same answer and I will show you.

x - 4 = 2x + 1

-x - 4 = 1

-x = 5

x = -5

Hope this helps!

8064 cartons in 21 days......8064/21 = 384 cartons per day

the cartons were delivered in cases of 6.....384 / 6 = 64 cases

each of 16 coffee shops received an equal number of cases..
64/16 = 4.....so each coffee shop received 4 cases per day <==
