Answer:

n = 4 and n = -10

Explanation:

l n + 3 l + 8 = 15

l n + 3 l = 7

Two solutions

n + 3 = 7

n = 4

and

n + 3 = -7 (since we are dealing with absolute numbers, one side has to be multiplied by -1)

n = -10

Experiments on learning in animals sometimes measure how long it takes a mouse to find its way through a maze. The mean time is
Sladkaya [172]

Answer:

Option A.

Step-by-step explanation:

In an experiment a mouse took the mean time to find its way through a maze = 18 seconds.

So the mean time μ = 18

So null hypothesis says,

H₀ : μ = 18

Then a researcher thought that the mice can complete the maze faster than the time taken earlier.

So he thinks mean time taken by 10 mice will be less than 18 seconds.

Or μ < 18

Alternate hypothesis says will be

Hₐ : μ < 18

Therefore, null hypothesis and alternate hypothesis will be

H₀ : μ = 18

Hₐ : μ < 18

Option A. will be the answer.

1 For each line
Elena-2011 [213]

Step-by-step explanation:

I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself

a)

The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line.  I'm going to use (4,0) and (7,3) as the 2 points.

m = (3-0)/(7-4) = 3/3 = 1

b)

The y-intercept is where the line intersects with the x-axis. In this case (0,-4)

c)

The equation of a linear line is y=mx+b (or c depending on which country you are from)

y = 1x-4

y=x-4

Now try the other 2 lines yourself!
