In the stock market an amazon stock share rose 4 and 1/2 points on Wednesday rose 3 and 3/8 points on Thursday and fell 2 and 1/
Vika [28.1K]

Answer:

In the three days the Amazon stock share rose by  5\frac{5}{8}

Step-by-step explanation:

Given:

Amazon stock share

rose 4 and 1/2 points on Wednesday

rose 3 and 3/8 points on Thursday

fell 2 and 1/4 points on Friday

To find the overall change.

Solution:

<em>The change in share on Wednesday is given as = +4\frac{1}{2}</em>

<em>The change in share on Thursday is given as = +3\frac{3}{8}</em>

<em>The change in share on Friday is given as = -2\frac{1}{4}</em>

Thus, the over all change is given by:

4\frac{1}{2}+3\frac{3}{8}-2\frac{1}{4}

<em>In order to combine mixed numbers, we will work the whole numbers and the fractions separately.</em>

⇒ (4+3-2)+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})

⇒ 5+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})

To combine fractions, we will take least common denominator.

<em>The L.C.D. 2,4 and 8 = 8  as it is the least common multiple for all the denominators</em>

So, we multiply the numerators with the corresponding numbers to make the denominators common.

⇒ 5+(\frac{1\times 4}{2\times 4}+\frac{3}{8}-\frac{1\times 2}{4\times 2})

⇒ 5+(\frac{4}{8}+\frac{3}{8}-\frac{2}{8})

Combining the numerators.

⇒ 5+\frac{4+3-2}{8}

⇒  5+\frac{5}{8}

⇒  5\frac{5}{8}

The overall change for the three days can be given as :  +5\frac{5}{8}

This means the share rose by  5\frac{5}{8}

Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20
Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e _{5}P_{2}.

But,

_{n}P_{r} = \frac{n!}{(n - r)!}

So that for _{5}P_{2}, n = 5 and r = 2.

_{5}P_{2} = \frac{5!}{(5 - 2)!}

     = \frac{5!}{3!}

    = \frac{5*4*3*2!}{3*2!}

Cancel out 3 and 2 with respect to the numerator and denominator.

_{5}P_{2} = 5 * 4

     = 20

Therefore,

_{5}P_{2} = 20

So that the correct option is D.

Find the fraction of stundents enrolled in each language
blondinia [14]

Fraction of students enrolled in Chinese = \frac{51}{126}

Fraction of students enrolled in French = \frac{33}{126}

Fraction of students enrolled in Spanish = \frac{42}{126}

Solution:

Total number of students = 51 + 33 + 42

                                          = 126

Number of students enrolled in Chinese = 51

Fraction of students enrolled in Chinese

             $=\frac{\text{Number of students enrolled in Chinese}}{\text{Total number of students}}

             $=\frac{51}{126}

Fraction of students enrolled in Chinese = \frac{51}{126}

Number of students enrolled in French = 33

Fraction of students enrolled in French

             $=\frac{\text{Number of students enrolled in French}}{\text{Total number of students}}

             $=\frac{33}{126}

Fraction of students enrolled in French = \frac{33}{126}

Number of students enrolled in Spanish = 42

Fraction of students enrolled in Spanish

             $=\frac{\text{Number of students enrolled in Spanish}}{\text{Total number of students}}

             $=\frac{42}{126}

Fraction of students enrolled in Spanish = \frac{42}{126}
