If the function 5x+y=1 has the domain (-2,1,6) then what is the corresponding range?
zysi [14]

The corresponding range of the domain is (11, -4, -29)

<h3>How to determine the range?</h3>

The function is given as:

5x + y = 1

Make y the subject

y = 1 - 5x

The domain is given as:

(-2,1,6)

Substitute these values in y = 1 - 5x

y = 1 - 5(-2) = 11

y = 1 - 5(1) = -4

y = 1 - 5(6) = -29

Hence, the corresponding range of the domain is (11, -4, -29)

lozanna [386]

Answer:

a) The test is left-tailed.

Step-by-step explanation:

a) Hypothesis testing is tagged two-tailled if the test checks for a claim in both directions (greater than and less than).

It is one tailed if it checks for a claim in only one direction (either greater than or less than). It is left-tailed of it is testing the claim in a less than direction and right-tailed if it is testing the claim in a greater than direction.

This question is to check results from a test of the claim that less than 8% of treated subjects experienced headaches. It is evidently left tailed.

Hope this Helps!!!
