Answer= Supplementary Angles
Supplementary angles are two angels whose sum is 180°
Answer:
3 (x - 1)
Step-by-step explanation:
Simplify the following:
3 - 2 (x + 1) + 5 x - 4
Grouping like terms, 3 - 2 (x + 1) + 5 x - 4 = -2 (x + 1) + 5 x + (3 - 4):
-2 (x + 1) + 5 x + (3 - 4)
3 - 4 = -1:
-2 (x + 1) + 5 x + -1
-2 (x + 1) = -2 x - 2:
5 x + -2 x - 2 - 1
Grouping like terms, 5 x - 2 x - 2 - 1 = (5 x - 2 x) + (-2 - 1):
(5 x - 2 x) + (-2 - 1)
5 x - 2 x = 3 x:
3 x + (-2 - 1)
-2 - 1 = -3:
3 x + -3
Factor 3 out of 3 x - 3:
Answer: 3 (x - 1)
Answer: Population parameter.
Step-by-step explanation:
Population parameter : It is a number that summarize a term for the whole population . For example :population proportion , population mean , etc.
Sample statistics: It is a number that summarize a term for the sample . For example : sample proportion , sample mean, etc.
By considering the given statement :
Population of interest : " all instructors at school "
Since 75% of all instructors at your school teach 2 or more classes.
It means , 75% is describing population proportion of all instructors at your school teach 2 or more classes..
i.e. The numerical value describes a population parameter.
That would be option B.
wriiten as below
x^2 + y^2 = 42
- the 42 = the square of the radius of the circle.
Answer : The number is 4.
Step-by-step explanation:
<u>Given : </u>
six times a number, increased by 3 is is 27.
<u>To Find: </u>
The number.
<u>Solution : </u>
Let the number is x
six times a number is 6x
Increased by 3 = 6x+3
According to the given question :
<u>Solving the value x : </u>
6x+3 =27
6x = 27-3
6x = 24
x = 24/6
x = 4
Hence, the number is 4.
