Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
105.6 L/h = 1.76 L/min :))))

Answer:
Step-by-step explanation:
Okay This is what is happening...
$955 total - $435 painting= $520 doll profit
First, subtract the painting Danika sold from the total. This will give you the amount she earned from the doll collection. Then, divide by the dollar amount to give the amount of dolls sold.
$520 doll profit divided by $20 = $26 fir each doll
or
Equation: 955=435-20d
Variable: d= number of dolls sold
Solve Equation: 955=435-20d
-435=-435
955-435=435-435-20d
520=20d
/20=/20 (I used "/" as my divide sign you can use the other one)
520/20=20/20
26=d
Final Answer: 26=dolls sold
Okay the answer is 3 3/4, 3÷4=.75 then put in the whole number and it is 3.75. 3.75 is bigger than 3.62.. so the answer is 3 3/4
Tenths: 2.1 hundredths:2.13 Tens:2
