Consider the function , f(x)=4x-5 what is the domain value that correspond to an output of f(x) = 11
kati45 [8]

Answer:

x = 4

Step-by-step explanation:

given f(x) = 11 then equate f(x) = 11 and solve for x

4x - 5 = 11 ( add 5 to both sides )

4x = 16 ( divide both sides by 4 )

x = 4 ← value of x in the domain

IgorC [24]

Answer:

3361 people should poll so it's inevitable that at least three people in the sample have identical demographic information.

Step-by-step explanation:

Consider the provided information.

There are 8 age and 7 income groups, 5 gender choices, and 6 choices for ethnicity.

For age we have 8 choices.

For Income groups we have 7 choices.

For gender groups we have 5 choices.

For ethnicity we have 5 choices.

Therefore, the total number of groups is: 8×7×5×6=1680

That means 1680 distinct group.

According to Pigeons holes principal: If m pigeons are in n holes and m > n, then at least 2 pigeons are in the  same hole.

So to select at least 2 people in the sample have identical demographic information 1681 people needs to poll.

In order to at least 3 people (2 × 1680+1) people should need to poll.

2 × 1680 + 1 = 3361

Hence, 3361 people should poll so it's inevitable that at least three people in the sample have identical demographic information.

RoseWind [281]

Answer:

  6/(49π) ≈ 0.03898 m/min

Step-by-step explanation:

  V = πr²h . . . . formula for the volume of a cylinder

  dV/dt = πr²·dh/dt . . . . differentiate to find rate of change

Solving for dh/dt and filling in the numbers, we have ...

  dh/dt = (dV/dt)/(πr²) = (6 m³/min)/(π(7 m)²) = 6/(49π) m/min

  dh/dt ≈ 0.03898 m/min
