If you apply the changes below to the linear parent function, f(x) = x, what is the equation fo the new function?
ad-work [718]

Answer:

D

Step-by-step explanation:

For a function in the form f(x) = x, we can say:

  • the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
  • the function -f(x) is the original, flipped over x-axis

<em>keeping the 2 rules in mind, we can say that</em>

<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>

<em>Then</em>

<em>flip over x-axis would make it f(x) = -3x</em>

<em />

answer choice D is right

Based on the sample of n = 25 healthy-weight students, can you conclude that healthy-weight students eat significantly fewer fat
Elis [28]

Answer:

z = -1.645

Step-by-step explanation:

b) n =25, M = 4.01 , \mu = 4.22 , \sigma = 0.60 , \alpha= 0.05

The hypothesis are given by,

H0 : \mu\geq 4.22 v/s H1 : \mu < 4.22

The test statistic is given by,

Check attachment for the formula that should br here.

z = \frac{4.01- 4.22 }{0.60 /\sqrt{25}}

= -1.75

The critical value of z = -1.645

The calculated value z > The critical value of z

Hence we reject null hypothesis.

The healthy-weight students eat significantly fewer fatty, sugary snacks than the overall population.
