The domain of the function shown in the graph is x>0.

What is a function?

A function is the relation between two sets. It relates from the domain set to the range set.

Here, the given graph represents an exponential function starting from (0, 0).

The given graph approaches towards the right along with the x-axis.

Therefore, the initial value of the independent variable in the given function is 0.

Hence, the domain of the given function is x>0.

The compressive strength of samples of cement can be modeled by a normal distribution with a mean of 6000 kilograms per square centimeter and a standard deviation of 100 kilograms per square centimeter. (a) What is the probability that a samples strength is less than 6250 kilograms per square centimeter? (b) What is the probability that a samples strength is between 5800 and 5900 kilograms per square centimeter? (c) What strength is exceeded by 95% of the samples?

Answers

Answer

a

[tex]\Phi (2.5) = 0.9938[/tex]

b

[tex]P(5800 <  X < 5900 ) =  0.13591 [/tex]  

c

[tex]x = 5835.5 [/tex]

Question

From the question we are told that

   The mean is  [tex]\mu  =  6000 \  kg/cm^2   [/tex]

    The standard deviation is  [tex]\sigma  =  100 \  kg/ cm^2 [/tex]

Generally the probability that a samples strength is less than 6250 kilograms per square centimeter is mathematically represented as

        [tex]P(X < 6250  ) =  P(\frac{ X - \mu}{\sigma } <  \frac{6250 - 6000 }{100}  )[/tex]

Generally [tex]\frac{X - \mu }{\sigma }  =  Z(The  \ standardized \  value  \ of  \  X )[/tex]

         [tex]P(X < 6250  ) =  P(Z< 2.5 )[/tex]

From the z-table  

      [tex]\Phi (2.5) = 0.9938[/tex]

Generally the probability that a samples strength is between 5800 and 5900 kilograms per square centimeter is mathematically represented as

    [tex]P(5800 <  X < 5900 ) =  P(\frac{5800 - 6000}{100} < \frac{X -\mu}{\sigma} <  \frac{5900 - 6000}{100}   )[/tex]

=> [tex]P(5800 <  X < 5900 ) =  P(-2< Z< -1   )[/tex]

=> [tex]P(5800 <  X < 5900 ) =  P(Z <  -1)  - P( Z< -2 )[/tex]  

From the z-table  

    [tex]P(Z <  -2)  = 0.02275[/tex]

and

    [tex]P(Z <  -1)  = 0.15866[/tex]

So

    [tex]P(5800 <  X < 5900 ) =  0.15866 - 0.02275[/tex]    

=>    [tex]P(5800 <  X < 5900 ) =  0.13591 [/tex]  

Generally the strength that is exceeded by 95% is mathematically evaluated  as

        [tex]P(X >  x) = 1-  P(\frac{X - \mu }{\sigma} \le  \frac{x- 6000}{100}) = 0.95 [/tex]

=> [tex]P(X >  x) =  P(Z \e \frac{x- 6000}{100}) = 0.05 [/tex]

From the normal distribution table  the critical value  of  0.05 is  

    [tex]z = - 1.645[/tex]

So

      [tex]\frac{x- 6000}{100} = - 1.645[/tex]

=>   [tex]x = (-1.645 * 100) + 6000[/tex]

=>   [tex]x = 5835.5 [/tex]

mckezie's rabbit ears 1/3 of a pound of food each day if mckenzie buys a 20 pound bag of food how many days will she be able to feed her rabbit

Answers

Answer:

She can feed her rabbit for 60 days!

Step-by-step explanation:

Turn 20 into a fraction:

[tex]\frac{20}{1}[/tex]

Make sure it has the same denominator:

(Remember: what you do to one side, you must do to the other)

[tex]\frac{20}{1} *\frac{3}{3}= \frac{60}{3}[/tex]

This means that if the rabbit eats 1/3 of a pound a day, she will be able to feed her rabbit for 60 days.

find the value of x in the triangle shown below

Answers

Using the Pythagorean Theorem, which is a^2 + b^2 = c^2, so it would be x^2 + 4^2 = 9^2
And then that would be:
x^2 + 16 = 81
So then by combining like terms:
x^2 = 65
So x = square root of 65.

the grade 8 has hired a disk jockey the disk jockey takes 85$ plus 2 for each student that attends. The disk jockey was paid 197 how many students attended

Answers

Answer:

56 students

Step-by-step explanation:

The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

The leg of a right triangle is 5 units and the hypotenuse is 8 units. What is the length, in units, of the other leg of the triangle?
89 Units

Answers

Answer:

The other leg is equal to 6.24 units.

Step-by-step explanation:

Using the Pythagorean Theorem:

[tex]a^2 + b^2 = c^2[/tex]

However we need to find b:

[tex]c^2-a^2=b^2[/tex]

Substitute:

[tex]8^2-5^2=b^2[/tex]

[tex]64-25=b^2[/tex]

[tex]b^2=39[/tex]

Find the square root:

[tex]\sqrt{39}=6.24[/tex]

The other leg is equal to 6.24 units.
