I think its D?
replace the x in the equation with -2
Answer:
using the formula
x/a + y/b =1(a= intercept on x axis; b= intercept on y axis)
x/-2 + y/6 =1
-1/2x + y/6 =1
multiply both sides by the l.c.m(6)
6(-1/2x +1/6y) =1x6
-3x +y =6
y = 3x +6(equation of the line)
Answer:
0.1587
Step-by-step explanation:
let X be the length of time (in seconds) an individual takes to use an ATM
X is N(100,10)
T = the duration (again, in seconds) of the period that starts when the first individual in queue accesses the ATM and ends when the last individual in queue leaves the ATM.
Required probability = P(T<360)
Here T = 4x
Hence T is N with mean = 400 and std dev = 40
Or
= Z is N(0,1)
=0.5-0.3413
=0.1587
