Mrrafil [7]

Answer:

10.14 years

Step-by-step explanation:

The following equation describes the percentage of all eligible voters that are registered to vote as a function of time:

V=100-30e^{-0.04t}

The time 't' for which V(t) = 80 is the amount of years required for the percentage of registered voters to reach 80%:

80=100-30e^{-0.04t}\\\frac{20}{30}= e^{-0.04t}\\ln(\frac{2}{3})=-0.04t*ln(e)\\ t=10.14\ years

It will take 10.14 years until 80% of all eligible voters in your county are registered to vote

y2 - y1 / x2- x1

-3-2/10-5

-5/5

-1

the mid point of the given points are

x= x1 + x2/2 , y= y1 +y2 /2

.

.

.

.

( , )

the equation of the line that passes through the given points are as

y+ y1 = m (x+ x1)

A blood bank needs 8 people to help with a blood drive. 11 people have volunteered.
11111nata11111 [884]

Answer:

165

Step-by-step explanation:

formula is

nCr = n!/(r!(n−r)!)

r= 8 = number of choosing objects from the set

n = 11 = total number of objects in the set

C(n,r)=C(11,8)

=11!/(8!(11−8)!)

! means factorial

factorial means to multiply by decreasing positive numbers.

For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320

=11!/8!×3!

= 165
