To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:

$\overline{x}\pm 2\sigma$ (1)

$\overline{x}$ : mean of brain volume = 1162.8 cm^3

σ: standard deviation = 127.1 cm^3

You replace the values of the parameters in the equation (1):

$1162.8cm^3+2(127.1cm^3)=1417cm^3\\\\1162.8cm^3-2(127.1cm^3)=908.6cm^3$

Limits = (1417 , 908.6)

The limits are 908.6 cm^3 and 1417cm^3

1337.0cm^3 is in between the limits calculated above.

What is the y-intercept of the function f(x)=4 - 5x? -5 -4 4 5

Len [333]

Answer:

Step-by-step explanation: Its 4 becuase you plug in the zero like this'

f(x)=4-5(0)

f(0)=4-0

f(0)=4

So it will (0,4)
