The body weight of a healthy 6 month old colt should be aboutµ = 85kg. a) If you want to set up a statisticaltest to challenge the claim that µ = 85 what would you usefor the null hypothesis H0 ?b) In Nevada there are many herds ofwild horses. Suppose that you want to test the claim that theaverage weight of a wild Nevada colt (3 mos old) is less than60kg. What would you use as the alternate hypothesisH1?c) Suppose that you want to test theclaim that the average weight of such a wild colt is greater than60 kg. What would you use for the alternate hypothesis?d) Suppose that you test the claimthat the average weight of such a wild colt is"different" from 60 kg. What would you use for thealternate hypothesis?e) For each of the test in parts b),c) and d), would the area corresponding to the P-value be on the left, on the right, or on both sides of themean?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
