Answer:

y = 25

Step-by-step explanation:

The formula to be evaluated is y = |-a^{2}|. The result is found by replacing the variables and making some algebraic handling:

y = |-5^{2}|

y = |-25|

y = 25

What is the equation of a line passing through the point (a, b) and having a slope of b?
andreev551 [17]
The equation of a line that passes thruogh the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)

so
passing through (a,b) and having slope of b is
y-b=b(x-a)

The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with mean o
prohojiy [21]

Answer:

The percentage of samples of 4 fish will have sample means between 3.0 and 4.0 pounds is 66.87%

Step-by-step explanation:

For a normal random variable with mean Mu = 3.2 and standard deviation sd = 0.8 there is a distribution of the sample mean (MX) for samples of size 4, given by:

Z = (MX - Mu) / sqrt (sd ^ 2 / n) = (MX - 3.2) / sqrt (0.64 / 4) = (MX - 3.2) / 0.4

For a sample mean of 3.0, Z = (3 - 3.2) / 0.4 = -0.5

For a sample mean of 3.0, Z = (4 - 3.2) / 0.4 = 2.0

P (3.2 <MX <4) = P (-0.5 < Z <2.0) = 0.6687.

The percentage of samples of 4 fish will have sample means between 3.0 and 4.0 pounds is 66.87%
