Answer:

c. d. different slopes; same y-intercept

for all the equations, when x = 0, y = -2

apart from the last equation which has no x-intercept.

They have different slopes i.e

y=x-2 has a slope of 1

y=2x-2 has a slope of 2

y=x-2 has a slope of 1

y=-2 has no slope

Two functions are given.

ArbitrLikvidat [17]

f(x) = g(x) if -x²+3x-2 - ( -x+1) = 0

-x² +3x-2 +x-1 = 0

-x² +4x -3 = 0

To solve, tou have to use the general method of resolution of a quadratic fonction.

To determine if it's has a solution in R, let's calculate Δ

Δ = (4)² - 4 * (1) *(-3)

Δ = 16 +12

Δ= 28

as Δ≥ 0 so the function allow two solution within R

so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2

S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2

S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2

S1 = -2 +√7 S2 = -2 -√7

So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7

The body weight of a healthy 3 month-old colt should be about μ = 60 kg. (Source: The Merck Veterinary Manual, a standard refere

tatuchka [14]

Answer:

The null hypothesis will be $H_o : \mu = 60 \ kg$

The alternative hypothesis will be $H_a : \mu < 60$

The alternative hypothesis will be $H_a : \mu > 60$

The alternative hypothesis will be $H_a : \mu \ne 60$

left; right; both

Step-by-step explanation:

Considering question a

The body weight of the colt is $\mu = 60 \ kg$

The null hypothesis will be $H_o : \mu = 60 \ kg$

Considering question b

Given that we want to test the claim that the average weight of a wild Nevada colt is less than 60 kg , then

The alternative hypothesis will be $H_a : \mu < 60$

Considering question c

Given that we want to test the claim that the average weight of such a wild colt is greater than 60 kg , then

The alternative hypothesis will be $H_a : \mu > 60$

Considering question d

Given that we want to test the claim that the average weight of such a wild colt is different from 60 kg , then

The alternative hypothesis will be $H_a : \mu \ne 60$

Considering question e

For question b , the corresponding p-value will be on the left because the average weight is less than 60 kg

For question c , the corresponding p-value will be on the right because the average weight is more than 60 kg

For question d , the corresponding p-value will be on both because the average weight is different from 60 kg
