Answer:
x is EQUIVALENT to 2.89
Step-by-step explanation:
You can do 200*.3(300 percent) and get 60.Subtract 60 from 200 and u get 140.
200 200
* .3 - 60
--------- ---------
60 140
this is one of the ways
Answer: By lurking variable she means a variable that is not among the variables studied but which affects the response variable.
Step-by-step explanation:
The existence of a negative correlation between variables in a research work suggests that a lurking variable is present in the data, which happens to be the case with the work of this researcher.
We have that
(r, ∅)----------> (-7, <span>5 pi/3)
we know that
</span>5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
The equation 7x + 3x - 18 = 6(x+3) is 9
<h3>What is equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
given:
7x + 3x - 18 = 6(x+3)
7x + 3x - 18 = 6x+18 [Distributive Property]
10x-18= 6x+18 [Addition Property of Equality]
10x-6x= 18+18 [Combine Like Terms ]
4x=36 [Subtraction Property of Equality]
4*x=36 [Multiplication Property of Equality]
x=36/4 [Division Property of Equality]
x=9
