Add 2 + 1 = 3 then 1/2 +1/2 =1
so 3 +1 = 4 and you have 1/4 left so your answer is 4 1/4

Find an equation of the line passing through the given points. Use function notation to write the equation. (3,8) and (4,13

Olegator [25]

Answer:

$f(x)=5x-7$

Step-by-step explanation:

The given line passes through the points;

$(x_1,y_1)=(3,8)$

and

$(x_2,y_2)=(4,13)$

Let us find the slope using;

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{13-8}{4-3}$

$m=\frac{5}{1}=5$

The equation is given by;

$y-y_1=m(x-x_1)$

We substitute the values into the formula to obtain;

$y-8=5(x-3)$

$y=5x-15+8$

$y=5x-7$

There the equation of the line is

$f(x)=5x-7$

Let f (x ) = 3x² - 4 and let g (x) = 2x + 1. <br> Find the value of f[g(2)].

stepan [7]

Answer:

The value of f[g(2)] is 71.

Step-by-step explanation:

We need to find f[g(2)].

The first step is finding f[g(x)]

We have that:

$f(x) = 3x^{2} - 4$

$g(x) = 2x + 1$

To find f[g(x)], the first step is replacing each x is f by g(x). So

$f(g(x)) = 3(2x+1)^{2} - 4$

Now we replace x by 2

$f(g(2)) = 3(2*2+1)^{2} - 4 = 75 - 4 = 71$

The value of f[g(2)] is 71.

Y = 4x - 3<br> (Solving for slope)

olasank [31]

Answer:

Slope = 4

Step-by-step explanation:

This is an equation of a line in the format y = mx + b

Lets match the two equations vertically to see which term is which

y = mx + b

y = 4x - 3

m is the slope, and it matches with the term "4"

That means that 4 is the slope

Parts of y = mx + b

y : output
m : slope
x : input
b : y - intercept

A randomly selected sample of 100 students had an average grade point average (GPA) of 3.2 with a standard deviation of 0.2.

alexdok [17]

Answer:

A. 0.020

Step-by-step explanation:

we calculate the standard error of the sample mean with the formula,

$E=\frac{s}{\sqrt{n} }$ ,

with E= standard error of the sample mean

s= standard deviation

n= sample

So,

s= 0.2

n= 100

$E=\frac{0.2}{\sqrt{100} } =\frac{0.2}{10}=0.02$
