<h3>How to know a polynomial?</h3>

Polynomials are algebraic expressions that consist of variables and coefficients.

In a simpler term a polynomial can have constants, variables and exponents, but never division by a variable.

Therefore, the polynomial among the options is as follows:

-6x³ + x² - √5

Answer:

The expected value of profit is -0.5125. This is expected loss as value is negative.

Step-by-step explanation:

We are given the following in the question:

P(winning) = 0.075

Thus,

P(Loosing) =

$1 - 0.075 = 0.925$

If we win we gain a profit of $5.50 and if we loose the lottery, we loose $1.

Thus, we can form the probability distribution in the following manner:

Event: Winning Loosing

Profit(x): +5.50 -1

P(x): 0.075 0.925

We have to calculate the expected value of the profit.

$E(X) = \displaystyle\sum x_i(P(x_i))\\E(x) = +5.50(0.075) + (-1)(0.925)\\E(x) = -0.5125$

Thus, the expected value of profit is -0.5125. This is expected loss as value is negative.

vredina [299]

Seven pizzas: 7 pizzas

Shared between 3 friends: 7 pizzas / 3 friends

Simplify the fraction:

7 / 3

(3 goes into 7 twice, 7 - 6 = 1)

2 1/3

The fraction of pizza that each friend gets is 2 1/3.

Hope this helps!! :)

Answer:

3.2%

Step-by-step explanation:

-Let r be the simple interest rate per annum.

-Given the total amount after 1 year is 1857.60, the initial amount is 1800

#We use the simple interest formula to find the rate of interest:

$Interest=Final\ Amount-Initial\ Amount\\\\=1857.60-1800\\\\=57.60\\\\I=Prt\\\\57.60=1800\times r\times 1\\\\r=\frac{57.60}{1800}\\\\=0.032\\\\=3.2\%$

Hence, the annual interest rate on the deposit is 3.2%
