4/7 = 12/21
12/21 = x + 3/21
9/21 = x
Hope this helped!!
The given variable is a continuous variable.
<h3>What is
continuous variable?</h3>
A quantitative variable can be either continuous or discrete depending on whether it is normally obtained through measurement or counting. A variable is continuous over a range of real values if it can take on any two specific real values and all other real values in between.
<h3>What is mercury thermometer?</h3>
In Amsterdam, physicist Daniel Gabriel Fahrenheit created the mercury thermometer, also known as a mercury-in-glass thermometer. It consists of a glass tube with a small diameter and a mercury bulb attached to it; the bulb contains far more mercury than the tube does.
<h3>According to the information:</h3>
A mercury thermometer was used to take the subject's temperature.
Because of the temperature:
- Not counting but measuring it.
- You can use a decimal number to represent its value.
- As a result, it is open to any value inside an interval.
- Temperature is therefore a continuous variable.
- The only format in which discrete values can be stated is as whole numbers.
so
Temperature is a continuous variable,

B.115,245
C.135,225
D.46, 314
Please Help ASAP!
Given the expression √(2cosx+1) = 0
Square both sides of the equation;
√(2cosx+1) = 0
2cosx + 1 = 0
2cosx = -1
cos x = -1/2
x = cos^-1(-1/2)
x = -60 degrees
Since cos is negative in the 2nd and 3rd quadrant then;
x = 180-60 = 120 degrees (2nd quadrant)
x = 270+60 = 330 degrees (3rd quadrant)
