Answer:
16/3
Step-by-step explanation:
The relationship between x and y is y=-4/3 x
So, when x = -4, y= -4/3(-4), or 16/3

Answer:
heyy sorry i dont really know what is the 'standard deviation' but as for the mean you go to add all the numebers together and divide them by the amount of numbers there are (7 in this scenario)
Step-by-step explanation:
21 + 29.5 + 38 + 46.5 + 55 + 63.5 + 72 = 325.5
then you divide 325.5 by the number of numbers present in the question
325.5 / 7 = 46.5
hope it helped :)
The correct answer is P = 0.1357.
In solving for the probability (P) that the 34-year olds
will spend more than $60 on fastfood, the mean and the standard deviation is to
be taken into account. The mean (μ) being the $44 average weekly expenditure; while
the standard deviation (σ) is $14.50. The formula goes this way P(X > 60) =
P( X−μ > 60−44 ) = P ( X−μ/σ > 60−44/14.50).
