21x + 84 + 12x - 16
33x + 68
The correct answer is 1.) 33x + 68.
Hope this helps!
If you try the given points in the offered equations, you find the only equation that makes sense is ...
y = 1/5x +2
_____
If you want to determine the equation yourself, you can use the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)*(x -x1) +y1
y = (6 -3)/(20 -5)*(x -5) +3
y = 3/15*(x -5) +3
y = 1/5x -1 +3
y = 1/5x +2
Answer:
10 pi
Step-by-step explanation:
The circumference for a circle is calculated by 2*pi*r or d*pi.
Here we are given the diameter (d) so we plug it in.
10*pi.
Therefore, this is the answer.
Answer: 239
Step-by-step explanation:
Given : Confidence level : 99%
Significance level :
Margin of error : E = 3 minutes
Population standard deviation :
To find : Numbers of observations are required. (Minimum Sample size)
Formula :
Using z-value table,
Two-tailed z-value for :
Using given values , we get
Hence, the minimum number of observation is required = 239
Answer:
The restriction of the domain of f(g(x)) is that x cannot be 3.
Step-by-step explanation:
The first step to solve this question is finding the function, replacing the values. So
The function is a fraction, which means that the restriction is that the denominator cannot be zero. So
The restriction of the domain of f(g(x)) is that x cannot be 3.
