Remark

The value of x is found by taking the sum of the two arcs (both given) and dividing that sum by two

Sub and solve

$\text{x} =\dfrac{\overset{\LARGE{\frown}}{NO} + \overset{\LARGE{\frown}}{PQ}}{2} = \dfrac{45+ 65}{2} = \dfrac{110}{2} = \text{55}$

Shawna has 3 adults 2 children coming over for dessert. she going to serve 2 small apple pies. if she plans to give each person,

Ostrovityanka [42]

First we have to find number of person.
3adults+2childre+Shawna=6 person
Now we have to divide 2 pie by 6 person to see how much pie each person get.
2:6= $\frac{2}{6} = \frac{1}{3}$ - its the result

Given f(x)=x^2+5 and g(x)=2x^3-1 find (f/g)(-3)

AlekseyPX

For this case we have the following functions:

$f (x) = x ^ 2 + 5\\g (x) = 2x ^ 3-1$

By definition of composition of functions we have:

$(f / g) (x) = \frac {f (x)} {g (x)}$

Then substituting:

$f (-3) = (- 3) ^ 2 + 5 = 9 + 5 = 14\\g (-3) = 2 (-3) ^ 3-1 = 2 (-27) -1 = -54-1 = -55$

So:

$(f / g) (- 3) = \frac {14} {- 55} = - 0.25$

Answer:

$(f / g) (- 3) = \frac {14} {- 55} = - 0.25$

You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $2; if

Kipish [7]

Answer:

E(Y) = $0.5

Var(Y) = 14.25

you should pay the same amount $0.5

Step-by-step explanation:

E(Y) = = Σ(YP)

P = probability of each outcomes.

Var(Y) = Σ $Y^{2}$ p − (μ x μ)

E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5

Var(Y) = ( $2^{2}\\$ x 0.25) + ( $6^{2}$ x 0.25) +( $-3^{2}$ x 0.5) - ( $0.5^{2}$ )

= 14.5 - 0.25

Var(Y) = 14.25

for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5
