The amount dispensed by a soft-drink dispensing machine has a normal distribution with mean μ and standard deviation 0.191 ounce
nirvana33 [79]

Answer:

The value of mean is  \mu = 15.64

Step-by-step explanation:

The normal distribution of the soft-drink dispensing machine can be stated statistically like

                   X ~ N (\mu ,0.191^2)

The standard form representation is

           P(X

     Now we need to obtain \mu in such a way that

                   P(X>16) = 0.01

   In standard form

       Since

                 P(Z>16 -\frac{\mu}{0.191} ) = 0.03

   This means

              P(Z

Now looking at the z-table for probability of 0.99 we obtain 1.88

    i.e

            16 - \frac{\mu}{0.191} = 1.88

Making \mu\ the \ subject

        16 - \mu = 1.88 *0.191

       \mu = 16 -(1.88*0.191)

          =15.64

We want to find the zeros of this polynomial:
SCORPION-xisa [38]

Answer:

x=0     x=2    x=7/2

Step-by-step explanation:

P(x) = 3x (x - 2) (2x - 7)

Set equal to zero

0  = 3x (x - 2) (2x - 7)

Using the zero product property

3x =0  x-2 =0   2x-7 =0

x=0      x=2    2x=7

x=0     x=2    x=7/2

F(x) = 3(3x + 4)<br> The inverse
Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

find the inverse of the function y=9x+12

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9x+12 becomes x=9y+12.

Now, solve the equation x=9y+12 for y.

f^{-1}(x) = (x-12)/9

y=(x−12)/9

A ladder is leaning against a building.The distance from the bottom of the ladder to the building is 6ft shorter than the length
Akimi4 [234]

Answer:

15 ft

Step-by-step explanation:

Hi, the illustration for the problem is a right triangle with:

hypotenuse (C)= the length of the ladder = L

horizontal side(A) = distance from bottom of the ladder to the building = L - 6

vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3

So, we can use Pythagoras formula:

A2 +B2= C2

(L – 6 )² + (L-3)² = L²

L²-12L+36+L²-6L+9 =L²

L2 -18L+45 =0

APPLYING QUADRATIC FORMULA WE OBTAIN:

L =15 OR L=3

If L=3

Vertical side = L-3 = 0 (Length can´t be 0)

So L=15
