<h3>
Answer: Approximately 2.33</h3>
The variance is given to be 5.43
Apply the square root to the variance to get the standard deviation
s = standard deviation
v = variance
s = sqrt(v)
s = sqrt(5.43)
s = 2.330326 which is approximate
s = 2.33
I rounded to 2 decimal places as this is the number of decimal places used for the variance.

Answer:

Step-by-step explanation:
Distribute 2 through the parentheses.
5x+3=-8x-10+2x
Collect like terms
5x+3=-6x-10
Move variable to the left-hand side and change its sign. Move constant to the right-hand side and change its sign.
5x+6x=-10-3
Collect like terms. Calculate the difference
11x=-13
Divide both sides by 11 and you get
x= -13/11

Answer:
a
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (4, - 1 ) and (x₂, y₂ ) = (- 2, 3 )
m =
=
=
= -
, then
y = -
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 2, 3 ) , then
3 =
+ c ⇒ c = 3 -
= 
y = -
x +
← in slope- intercept form
multiply through by 3 to clear the fractions
3y = - 2x + 5 ( subtract - 2x + 5 from both sides )
2x + 3y - 5 = 0 ← in general form
