Answer:

Step-by-step explanation:

a) P(80 < X < 110) for N(100,15)

Mean 100 sd=15  

z F (x)

80 -1.333333333 0.09121122

110 0.666666667 0.747507462

 

P(80<x<110) 0.656296243

b. P(1.50 < X < 2.00) for N(0,1)

z F (x)

1.5 0.933192799

2 0.977249868

P(1.50 < X < 2.00) =0.04406

c. P(4,500 < X < 7,000) for N(6000,1000)

6000 1000  

z F (x)

4500 -1.5 0.066807201

7000 1 0.841344746

 

P(4500<x<7000) 0.774537545

d. P(225 < X < 450) for N(600,100)

600 100  

z F (x)

225 -3.75 8.84173E-05

450 -1.5 0.066807201

 

P(225<x<450) 0.066718784

The inverse, f'(x), of f(x) =
astraxan [27]

Step-by-step explanation:

Given

f(x) =  \frac{x + 5}{x}

So

f(2) = \frac{2 + 5}{2}  \\  =  \frac{7}{2}

Now

{f}^{ - 1} (x) =  \frac{5}{x - 1}

So

{f}^{ - 1} (2) =  \frac{5}{2 - 1} \\  =  \frac{5}{ 1}   \\  = 5

Hope it will help :)❤

the elephants at the norfolk zoo are fed 1/2 a barrel of corn each day. the buffalo are fed 7/10 as much corn as the elephants.
maksim [4K]

7/20 barrels of corn are the buffalo fed each day.

How to solve word problems?

It's actually fairly easy to solve word problems using a tried-and-true step-by-step approach.

  • Aloud to yourself, read the issue.
  • Make a Drawing.
  • Ask yourself, "What am I looking for?"
  • List the items that have been provided.
  • Locate the key phrases.
  • Solve.
  • Verify your work.

Here are some actions to take:

  1. Recognize the issue, including all the terminology used to describe it. Recognize what you need to look for, Recognize the issue's context.
  2. Convert the issue into an equation. Give the unknown a variable (or variables) to symbolize, Indicate exactly what the variable stands for.
  3. Put the strategy into action and find a solution.

Given:

Elephants at the Norfolk zoo are fed = 1/2

Buffalo are fed 7/10 as much corn as the elephants = 7/10 * Elephants fed

= 7/10 * 1/2

= 7/20

Hence, 7/20 barrels of corn are the buffalo fed each day.
