I think this is it, i would like for u to get a second opinion.
27 because you have to divide 54 pencils by two people
Answer:
The expected number of appearance defects in a new car = 0.64
standard deviation = 0.93(approximately)
Step-by-step explanation:
Given -
7% had exactly three, 11% exactly two, and 21% only one defect in cars.
Let X be no of defects in a car
P(X=3) = .07 , P(X=2) = .11 , P(X=3) = .21
P(X=0 ) = 1 - .07 - .11 - .21 = 0.61
The expected number of appearance defects in a new car =
E(X) =
=
= 0.64
= variation of E(X) =
= 
=
= 0.8704
standard deviation =
=
= 0.93(approximately)
Answer:
No!
Step-by-step explanation:
Prime is anything that cannot be divided into but by one and itself, therefore all even numbers are Composite.
First lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
1 kg --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09
