20% of $50 is:
$50* (20/100)= $10.
$50- $10= $40
The new price is $40.
Hope this helps~
4 x 27 = 108 and 4 + 27 = 31... I don't think there is any pair of numbers that would equal -31. So the answer would be 4 and 27. Good luck! Hope this helped!!
Answer:
Third option.
Step-by-step explanation:
In the picture attached, the question is shown. There we can see that as x gets bigger (x → ∞), f(x) gets smaller (f(x) → -∞ ). On the other hand, as x gets smaller (x → -∞), f(x) gets bigger (f(x) → ∞ ).
Answer:
0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean = 
a)
: N(78, 4)
b) 
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
Answer:
MK = 14
Step-by-step explanation:
MK = ML + LK , substitute values
4x - 2 = 8 + x + 2
4x - 2 = x + 10 ( subtract x from both sides )
3x - 2 = 10 ( add 2 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Thus
MK = 4x - 2 = 4(4) - 2 = 16 - 2 = 14
