What is the least common denominator of the rational expressions below?<br> 1/x^2 - 4/3x^2+15x
vladimir1956 [14]

Answer:

The LCD is 3x²

The other two denominators can be factors of 3x²

Step-by-step explanation:

To get the equivalent fractions, divide the original denominator into the LCD, then multiply the original numerator by the quotient.

For the first term: 1/x²

3x² ÷ x² = 3 3×1=3 The equivalent is 3/3x²

Second term: Leave it as it is.

For the third term: 15x

The implied denominator is 1

3x² ÷ 1 = 3x² 3x² × 15 = 135x²

The equivalent is 135x²/3x²

<em>To </em><em>check</em><em> </em><em>the </em><em>validity</em><em>,</em><em> </em><em>substitute</em><em> </em><em>a </em><em>value</em><em> </em><em>for</em><em> </em><em>x </em><em>and </em><em>calculate</em><em> </em><em>the</em><em> </em><em>numbers</em><em>.</em>

<em>For</em><em> </em><em>example</em><em> </em><em>let </em><em>x </em><em>=</em><em> </em><em>3</em>

<em>The </em><em>original</em><em> </em><em>expression</em><em> </em><em>becomes</em><em> </em>

<em>1/3² + 4/3(3²) - 15(3)</em>

<em>1</em><em>/</em><em>9</em><em> </em><em>+</em><em> </em><em>4</em><em>/</em><em>2</em><em>7</em><em> </em><em>-</em><em> </em><em>4</em><em>5</em>

<em>With</em><em> </em><em>the</em><em> </em><em>LCD </em><em>it </em><em>is</em>

<em>3</em><em>/</em><em>2</em><em>7</em><em> </em><em>+</em><em> </em><em>4</em><em>/</em><em>2</em><em>7</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em>1</em><em>5</em><em>/</em><em>2</em><em>7</em>

Every day a kindergarten class chooses randomly one of the 50 state flags to hang on the wall, without regard to previous choice
Romashka [77]

Answer:

a)   S=50

    P(X)=0.02

b)  P(W,M,C)=8*10^-^6

c)  P(W_2_3)=1.18*10^-^3

Step-by-step explanation:

From the question we are told that

Sample space S=50

Sample size n=30

a)Generally the sample space S is

S=50

The probability measure is given as

P(X)=\frac{1}{50}

P(X)=0.02

b)

Generally the probability that  the class hangs Wisconsin’s flag on Monday, Michigan’s flag on Tuesday, and California’s flag on Wednesday is mathematically given as

Probability of each one being hanged is

P(X)=\frac{1}{50}

Therefore

P(W,M,C)=\frac{1}{50} *\frac{1}{50}* \frac{1}{50}

P(W,M,C)=\frac{1}{125000}

P(W,M,C)=8*10^-^6

c)Generally the probability that Wisconsin’s flag will be hung at least two of the three days is mathematically given as

Probability of two days hung +Probability of three days hung

Therefore

P(W_2_3)=^3C_2 (1/50) * (1/50) * (49/50) +^3C_3 (1/50) * (1/50) *(1/50)

P(W_2_3)=148 / 125000

P(W_2_3)=1.18*10^-^3
