Solve the simultaneous equations using an algebraic method.<br> x + 2y = 13<br> 3x + y = 24

Firlakuza [10]

X=7, y=3
because it is an algebraic method you have to solve for an x or y in either equation, and then plug that into the other equation. it’s helpful for these problems to check your work and plug the numbers back into the equations and the end for future reference !

Need to turn this in asap

OleMash [197]

Between two consecutive numbers 5 and 6 √34 is.

Here we have to find the two whole numbers, between which √34 is.

√25 = 5 and √36 = 6

25 < 34 < 36

Now taking root, we have

√25 < √34 < √36

5 < √34 < 6

Since √25 =5 and √36 = 6, it is known that √34 is between 5 and 6.

To know more about the roots refer to the link given below:

Real estate ads suggest that 56 % of homes for sale have garages, 27 % have swimming pools, and 16 % have both features. a) W

Marizza181 [45]

Answer:

a) 0.4

b) 0.28

c) The events are not independent

d) The events are not mutually exclusive

Step-by-step explanation:

Hi!

Lets call:

Gar = {homes with garage}

Pool = {homes with pool},

A = {homes with pool and garage} = Gar ∩ Pool

The data we are given is:

P(Gar) = 0.56

P(Pool) = 0.27

P(A) = 0.16

a) B = {homes with garage but not pool}. This set B is the set Gar without set A: B = Gar / A

P(B) = P(Gar) - P(A) = 0.4

b) This is a conditional probability:

P(Pool | Gar) = P(Gar ∩ Pool) / P(Gar) = 0.16/0.56 = 0.28

c) To be independent events, it must be, by definition:

P(Gar ∩ Pool) = P(Gar) * P(Pool)

0.16 ≠ 0.56*0.27 = 0.15

Then, the events Gar and Pool are not independent

d) Gar and Pool are not mutually exclusive, because there are houses with both pool and garage. We know that because P(A) is not zero.

Which expression is a polynomial

patriot [66]

Answer:

$4x^3-2x^2+5x-6+\frac{1}{x}$ is a polynomial

Step-by-step explanation:

a polynomial is a set of numbers with multiple terms that are not simplify able

$9x^7y^{-3} z$ is not a polynomial because its actually one term, there is no addition/subtraction of different terms.

-13 is a single number, so not a polynomial

13x^-2 is also a single number, not a polynomial
