Through: (3,5), slope=5\3

ANEK [815]

So slope intercpet form
y=mx+b

m=slope
b=y intercpet

slope=5/3
in (x,y) form

x=3
y=5 is one point

subsitute and solve for b
y=mx+b
5=5/3 times 3+b
5=3/3 times 5+b
5=1 times 5+b
5=5+b
subtract 5 from both sides
0=b

equation is
y=5/3x+0 or
y=5/3x

What is the variance for this activity? activity a m b t es ef ls lf 7 1 1.5 2 1.50 8 9.50 8 9.50

Lina20 [59]

The variance for this activity is mathematically given as

Var=0.026

<h3>What is the variance for this activity?</h3>

A data set's variance may be seen as a measurement of the spread that exists between the individual integers. When evaluating the asset allocation of a portfolio, investors employ an expression known as the variance equation.

After careful consideration of the table given in the question, we have that

Pessimistic time tp=2

optimistic time to=1

most likely time tm=1.5

Generally, the equation for variance is mathematically given as

$\sigma^2=\frac{tp-to}{6}^2$

Therefore

$\frac{2-1}{6}^2\\\\\sigma^2=1/6^2$

Var=0.026

In conclusion, the variance for this activity

Var=0.026
