Women have pulse rates that are normally distributed with µ = 77.5 beats per minutes and σ = 11.6 beats per minutes. What is the probability that 10 randomly selected women will have a mean pulse rate greater than 75 beats per minute?

6 equilateral triangles

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
