It's not clear what polynomial you posted, but let's say you had the polynomial

5x^3+7x^2-9x+10

This is a cubic polynomial as the largest exponent is 3. The degree is also 3. The degree of the polynomial is equal to the largest exponent.

N a region, there is a 0.70.7 probability chance that a randomly selected person of the population has brown eyes. assume 1414

taurus [48]

'll use the binomial approach. We need to calculate the probabilities that 9, 10 or 11
people have brown eyes. The probability that any one person has brown eyes is 0.8, 
so the probability that they don't is 1 - 0.8 = 0.2. So the appropriate binomial terms are 

(11 C 9)(0.8)^9*(0.2)^2 + (11 C 10)(0.8)^10*(0.2)^1 + (11 C 11)(0.8)^11*(0.2)^0 = 

0.2953 + 0.2362 + 0.0859 = 0.6174, or about 61.7 %. Since this is over 50%, it 

is more likely than not that 9 of 11 randomly chosen people have brown eyes, at 
least in this region. 

Note that (n C r) = n!/((n-r)!*r!). So (11 C 9) = 55, (11 C 10) = 11 and (11 C 0) = 1.

You will write a 5-paragraph essay explaining how you would solve the following equation:

sattari [20]

Answer:

$x=0$

Step-by-step explanation:

$\frac{7}{3}(2x+3)+\frac{3}{4}(\frac{x}{5}-\frac{15}{2})=\frac{11}{8}$ <-- Given

$\frac{14}{3}x+7+\frac{3}{20}x-\frac{45}{8}=\frac{11}{8}$ <-- Distributive Property

$\frac{280}{60}x+7+\frac{9}{60}x-\frac{45}{8}=\frac{11}{8}$ <-- Find LCD of x-terms

$\frac{289}{60}x+7-\frac{45}{8}=\frac{11}{8}$ <-- Combine Like Terms

$\frac{289}{60}x+7=\frac{56}{8}$ <-- Add 45/8 to both sides

$\frac{289}{60}x+7}=7$ <-- Simplify Right Side

$\frac{289}{60}x=0$ <-- Subtract 7 on both sides

$x=0$ <-- Divide both sides by 289/60

Mario and Luigi have friends. They want to purchase some extra controllers. Each controller costs $29.99.

jonny [76]

An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:

Let x = number of consoles to be bought
y = number of games to be bought
z = number of controllers to bebought
C = total cost of all

The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,

C = 299x + 59.99y + 29.99z
