When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of 61.1 oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). 66.1, 64.7, 65.3, 68.5, 65.7, 64.7, 61.3, 66.1, 67.2, 65.6Use the α=0.01 significance level to test the claim that the mean weight is higher with the enriched feed. The sample mean is x⎯⎯⎯= The sample standard deviation is s= The test statistic is t= The critical value is t=

where is the shape my dude?

step-by-step explanation:

rounding to the nearest thousandth would be 452,000

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
