The coordinates of C' are 3 times those of C.
3×(2, -1) = (6, -3)
The appropriate selection is ...
(6, -3) . . . . . . . . . the 4th one
Answer: 17.89
Step-by-step explanation:
In binomial distribution, the standard deviation is given by :-
As per given , we have
The number of vouchers in the sample with errors is denoted by x.
p= 0.20 , n = 2000
Then , 
Hence, the standard deviation of x is 17.89.
Answer: 50%
Step-by-step explanation: there are 4 options and it’s the probability of getting two
Area = length of base × altitude
34 = 8.5 × a
34 = 8.5a
a = 34/8.5
a = 4
The altitude of the corresponding side is 4 cm
·
=
. This can be simplified to 5x
, because √50 simplifies to 5√2 (since 5x5x2 equals 50) and the square root sign takes x² from x³ and turns it into just x.
