What's -8 + (-1 1/8)

gogolik [260]

I think the answer is 9.375 if it needs to be in decimal form. If it needs to be in fraction form it would be improper, 9 3/8 would be the fraction. Hope it helps!

Answer:

discriminant =0

1 real root

Step-by-step explanation:

The discriminant is b^2 -4ac

when the equation is written in the form ax^2 +bx+c

f(x) = 3x^2 +24x+48

a = 3 b = 24 and c =48

discriminant = 24^2 - 4(3)*(48)

=576-576

=0

If the discriminant >0 we have 2 real roots

if discriminant = 0 we have 1 real root

if discriminant <0 we have 2 complex roots

A package delivery company experiences high variability in daily customer demand, which in turn results in high variability in t

Ilya [14]

Solution :

Let :

X = number of overtime hours

S = total weekly salary

S = $12 \times 40 + 18 \times X$

S = 480 + 18X

E(S) = $480 + 18 \times E(X)$

$E(S) = 480 + 18 \times 15$

= 750

Mean of S = 750

Var (S) = $18^2 \times Var(X)$

Var(S) = $18^2 \times 4^2$

= 5184

Variance of S = 5184

The standard deviation equals square root of 5184 = 72
