EXPLANATION

Dividing 10 by 4 (4%=0.04) and multiplying by 100 give us the corresponding 100% number as shown as follows:

10\cdot\frac{100}{4}=250

A manager at a local company asked his employees how many times they had given blood in the last year. The results of the survey
Lubov Fominskaja [6]

Answer:

Var(X) = E(X^2) -[E(X)]^2 = 4.97 -(1.61)^2 =2.3779

And the deviation would be:

Sd(X) =\sqrt{2.3779}= 1.542 \approx 1.54

Step-by-step explanation:

For this case we have the following distribution given:

X        0         1       2       3       4         5        6

P(X)  0.3   0.25   0.2   0.12   0.07   0.04   0.02

For this case we need to find first the expected value given by:

E(X) = \sum_{i=1}^n X_i P(X_I)

And replacing we got:

E(X)= 0*0.3 +1*0.25 +2*0.2 +3*0.12 +4*0.07+ 5*0.04 +6*0.02=1.61

Now we can find the second moment given by:

E(X^2) =\sum_{i=1}^n X^2_i P(X_i)

And replacing we got:

E(X^2)= 0^2*0.3 +1^2*0.25 +2^2*0.2 +3^2*0.12 +4^2*0.07+ 5^2*0.04 +6^2*0.02=4.97

And the variance would be given by:

Var(X) = E(X^2) -[E(X)]^2 = 4.97 -(1.61)^2 =2.3779

And the deviation would be:

Sd(X) =\sqrt{2.3779}= 1.542 \approx 1.54

What is the completely factored form of x3 â€"" 64x? x(x â€"" 8)(x â€"" 8) (x minus 4) (x squared 4 x 16) x(x â€"" 8)(x 8) (x â€
Vadim26 [7]

The factored form of an equation is done by rewriting the equation in simpler forms.

The completely factored form of x^3 - 64x is x(x-8)(x + 8)

The expression is given as:

x^3 - 64x

Factor out x from the expression, x^3 - 64x

x^3 - 64x = x(x^2-64)

Express 64 as 8^2

x^3 - 64x = x(x^2-8^2)

Express the expression as a difference of two squares

x^3 - 64x = x(x-8)(x + 8)

Hence, the completely factored form of x^3 - 64x is x(x-8)(x + 8)
