Answer:

Begin at 53. Travel 34 units to the left.

Step-by-step explanation:

how to represent 53 – 34 on a number line.

53 - 34, it means we are subtracting 34 from 53

while subtracting the answer will be less than 53. we move left for subtracting

So we start number line at 53

From 53 we move 34 units left for subtracting. so we land at 19

53 - 34= 19

Begin at 53. Travel 34 units to the left.

The Wall Street Journal reported that the median salary for middle-level manager jobs was approximately $85,000 (The Wall Street
vredina [299]

Answer:

Median = $80,000 ; Mean = $84,000 ; Q1 = 67,000 ; Q3 = 106,000

Step-by-step explanation:

Given the data :

108 83 106 73 53 85 80 63 67 75 124 55 93 118 77

Reorderd data :

53, 55, 63, 67, 73, 75, 77, 80, 83, 85, 93, 106, 108, 118, 124

The median salary:

1/2(n+1)th term

Sample size, n = 15

1/2 (15 + 1)th term

1/2(16)th term

8th term = 80

Median is $80,000

Median reported by Wall Street Journal approximately $85000

The obtained and reported values are close

The mean annual salary :

ΣX / n = 1260 / 15 = 84

Mean annual salary = $84,000

Mean is the average of all earnings combined, median is the mid value of he data.

First and third quartile :

Q1 = 1/4(n+1)th term

Q1 = 1/4(16)th term

Q1 = 4th term = 67

Third quartile:.

Q3 = 3/4(n+1)th term

Q3 = 3/4(16)th term

Q3 = 12th term = 106

Drag each tile to the correct box. Not all tiles will be used.
const2013 [10]

Answer:

Step-by-step explanation:

f(x) = y = 3x/(8 + x)   (I am assuming that the 8 + x is the denominator. Please use parentheses in the future if you forgot this. If there are no parentheses, then my solution will not work for you.)

 

Exchange x and y; that is, replace x by y and y by x simultaneously:

 

x = 3y/(8 + y).

 

Then use algebra to solve for y in terms of x:

 

(8 + y)x = 3y    (multiply both sides by the denominator to clear the fraction)

8x + xy = 3y     (distribute)

xy − 3y = −8x     (rearrange terms with all y's on the left side of the equation)

y(x − 3) = −8x    (factor out y as a common factor)

y = −8x/(x − 3)    (divide by x − 3)

 

Finally, replace y by f-1(x):

 

f-1(x) = −8x/(x − 3).

 

This is the inverse of f(x). It can be checked by finding f(f-1(x)) and f-1(f(x)), and verifying that both equal x after simplifying.

Which method is the best method for solving the equation 8x² – 13x + 3 = 0?
mart [117]
Quadratic formula is the bestt
by applying it
8x^2-13x+3
 x^2-13x/8+3/8=0
 x^2-13x/8=3/8
 x^2-13x/8+169/256
=73/256
 (x-13/16)^2
=73/25
so correct option is D 
hope it helps
