Answer:
Standard deviation =2.6
Step-by-step explanation:
Using the formula given
S = √((1/n-1)∑(x-x⁻)²)
n = 5
∑(x-x⁻)² = 34
Therefore;
s = √(1/5(34)
= √6.8
= 2.6
The standard deviation will be 2.6
Answer: 2.9 just did it on apex 6/8/2019
Step-by-step explanation:
40% = .4 because % means hundredths. So 40% = 40/100 = .4
Let x be the total number of marbles.
Then, .4x = 24
Divide both sides by .4
x = 60 and 24 is 40% of 60 marbles
2.007; 2.714; 2.09; 2.97
