step one and two is wrong because when you're distributing this equation u should get -24+4y+4=-4 u caculate and then u move the constant to the right side and caculate again then divide

The volume of a box(V) varies directly with its length(l). Using k for the constant of proportionality, express the relationship

pochemuha

Answer: V = L (k)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

Volume of a box = V
Length = l
Constant of proportionality = k

We know that the volume of the box (V) varies directly with its length (l).

So, the expression for the volume is:

V = L (k)

Assume that the pond contains 90 fish: 64 purple, 25 green, and 1 red. A contestant pays $0.55 to randomly catch one fish and re

Answer:

The carnival is losing (on average) $0.15 on each play

Step-by-step explanation:

To find out how much the carnival wins or looses in each play one subtract the expected value (EV) from each play from the amount charged by the carnival for each play ($0.55). If the expected value is higher than what the carnival charges, the carnival is losing money.

Expected is the sum of the payouts of each bet multiplied by its likelihood:

$EV= \frac{64*0.40+25*1.15+1*9.00}{90}\\EV= 0.70$

Since the expected value is higher than $0.55, the carnival is losing money, on average, on each play:

$0.55-0.7 = -0.15$

The carnival is losing (on average) $0.15 on each play

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero

stira [4]

If - 1 is a zero then
$(x + 1)$
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

$4 {x}^{2} + 3x - 10$
(see attachment).

We can rewrite the polynomial as
$f(x) = (x + 1)(4 {x}^{2} + 3x - 10)$

We can further factor as

$f(x) = (x + 1)(4 {x}^{2} - 5x + 8x - 10)$
That is

$f(x) = (x + 1)(x + 2)(4x - 5)$
