Mathematics
1 answer:
lisabon 2012 [21]3 years ago
3 0

Answer: -6

Step-by-step explanation:

Rewrite the expression:

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

Factor out the negative:

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

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

Rewrite the sum:

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

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

Calculate the sum:

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

-(5+1)

Solve:

-(5+1)

-6

2u + 9 = 5u - 48

3u = 57

u = 19

EI = 5* 19 - 48 = 47

Determine+the+percentile+indicating+the+bottom+ranking+20%.+in+other+words,+what+is+the+dollar+number+that+defines+where+the+low
Aloiza [94]

The dollar number that defines where the lowest values falls is

20% percentile value =$20

This is further explained below.

<h3 /><h3>What is the dollar number that defines where the lowest value falls?</h3>

Generally,  Now we need to determine the 20th percentile ($20). It indicates that we need to locate a dollar amount that marks the point at which the 20 % data has a value lower than that number.

i=(p/100)*n

Where i is the position of p^th

percentile when the data is presented in ascending order.

i=20/100*50

i=1000/100

i=10

Therefore

n=50

p=20

In conclusion, the 10th position for given data is 20,

Therefore, 20% percentile value =$20
