Answer:  a & b

<u>Step-by-step explanation:</u>

The sum of the probabilities should equal 1.0

a) <u>probability of 5/3 is greater than 1</u> shows that the probability distributions will result in a sum greater than 1.    

b) <u>The sum of the probabilities is 31/12</u> shows that the sum of the probability distributions is unequal to 1.0.

c) <u>The result is less than 0</u> is irrelevant.  The data could be temperature <em>(or something else which can be measured as a negative value).</em>

d) <u>The probabilities have different denominators</u> is irrelevant. Fractions can be reduced and unlike denominators can be turned into like denominators.  The most important thing is that their sum is 1.0.

Factor 4a^2-b^2-2a+b
Marianna [84]

Answer:Equation at the end of step 1

 

STEP

2

:

           4a2 - b2

Simplify   ————————

            2a - b  

Trying to factor as a Difference of Squares:

2.1      Factoring:  4a2 - b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  4  is the square of  2  

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (2a + b)  •  (2a - b)  

Canceling Out :

2.2    Cancel out  (2a - b)  which appears on both sides of the fraction line.

Final result :

 2a + b

In ΔUVW, the measure of ∠W=90°, the measure of ∠U=40°, and WU = 1.8 feet. Find the length of UV to the nearest tenth of a foot.
Dmitry_Shevchenko [17]

Answer: 2.3

Step-by-step explanation:

​

=

x

1.8

​

\cos 40=\frac{1.8}{x}

cos40=

x

1.8

​

x\cos 40=1.8

xcos40=1.8

Cross multiply.

\frac{x\cos 40}{\cos 40}=\frac{1.8}{\cos 40}

cos40

xcos40

​

=

cos40

1.8

​

Divide each side by cos 40.

x=\frac{1.8}{\cos 40}=2.3497\approx 2.3\text{ feet}

x=

cos40

1.8

​

=2.3497≈2.3 feet

Is the sum of two monomials always a monomial? Is their product always a monomial?
Ivan

Sum of two monomials is not necessarily always a monomial.

For example:

Suppose we have two monomials as 2x and 5x.

Adding 2x+5x , we get 7x.

So if two monomials are both like terms then their sum will be a monomial.

Suppose we have two monomials as 3y and 4x

Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.

So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.

Product of monomials:

suppose we have 2x and 5y,

Product : 2x*5y = 10xy ( which is a monomial)

So yes product of two monomials is always a monomial.
