Serhud [2]3 years ago
7 0

get a common denominator which is 24

3 7/8 = 3 21/24

6 /4 = 6 6 /24

3 21/24 - 6 6 /24

big number minus small number take sign of larger

6 6/24

- 3 21/24

-------------


5  30/24

3  21/24

--------------

2  9/24


2 3/8

the sign of the larger is negative

-2 3/8

The table represents the linear function f(x), and the equation represents the linear function g(x).
Eva8 [605]

9514 1404 393

Answer:

  The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

Step-by-step explanation:

The y-intercept is the function value when x=0. The table shows f(0) = 1. The equation shows g(0) = 1, so the y-intercepts are equal.

__

The value of f(x) changes by (11 -1) = 10 when the value of x changes by (2 -0) = 2. That means the slope of f(x) is 10/2 = 5.

The slope of g(x) is the x-coefficient, 4. We note that 5 > 4, so the slope of f(x) is greater than for g(x).

The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

the results of a poll indicate that between 33% and 37% of the population of a town visit the library at least once a year. what
Vera_Pavlovna [14]

The margin of error is ±2%

<h3>What is Margin error?</h3>

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.

Let x be margin of error and y be the percentages of the population.  

So,

y-x =33%

y +x = 37%

Solving above equations

2y= 70

y= 35%

and x= 2%

Hence, the margin of error is ±2%.
