Express the line in slope intercept form
this is done by making y the subject.
y = 3x/2 + 4
slope is 3/2
product of perpendicular lines is negative one
let me slope of the other line
m * 3/2 = - 1
m = - 2/3
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:
Two sets are called disjoint if they have no elements in common. For example:
The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.
Another way to define disjoint sets is to say that their intersection is the empty set,
Two sets A and B are disjoint if A ∩ B = 0.
In the example above,
S ∩ T = ∅ because no number lies in both sets.
Step-by-step explanation:
Rounded up to 0.4
ffffffffff
Yes
Step-by-step explanation:
4×7=28
and 7×4 also equal to 28
