Answer:
Step-by-step explanation:
let the number be x
(x+6)/3 =21
x+6=21*3
x+6=63
x=57
Answer:
(f o g)(4) = 45
Step-by-step explanation:
f(x)=4x+1
g(x)=x²-5
(f o g)(4)=?
(f o g)(4) = f(g(4))
Calculating g(4):
x=4→g(4)=4²-5
g(4)=16-5
g(4)=11
Replacing g(4)=11
(f o g)(4) = f(g(4))
(f o g)(4) = f(11)
Calculating f(11)
x=11→f(11)=4(11)+1
f(11)=44+1
f(11)=45
Replacing f(11)=45:
(f o g)(4) = f(11)
(f o g)(4) = 45
Answer:
Step-by-step explanation:
1) The sample and the population of this study is the friends who replied his email which includes in his contact list. then, the number of the replied to his email are 9 friends.
population: the whole friends include in his contact list.
3) Type I error occurs when one incorrectly rejects the null hypothesis
Here there is possibility of type I error
Answer:
y= 3/5x + 1
Step-by-step explanation:
Slope intercept form is modeled by the equation y=mx+b.
M = slope, while B = y-intercept.
The y-intercept in this scenario equals (0, 1) or just simply 1.
The slope equals 3/5. This can be found with rise/run or y/x.
Answer:
18
Step-by-step explanation:
4x+100+3x+79=32
7x+179=32
7x=-147
x=-21
Now, plug in the numbers.
3(-21)+79=-61+79
=18
