Answer:

a

 [tex]P(0.51 <  \^ p <  0.61 ) =  0.2587 [/tex]

b

 [tex]P(\^ p > 0.71 ) = 0.15165[/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion  is  [tex]p = 0.64[/tex]  

   The sample size is n =  50

Generally the mean of this sampling distribution is  

       [tex]\mu_{x} = p = 0.64[/tex]

Generally the standard deviation is mathematically represented as

      [tex]\sigma  =  \sqrt{ \frac{p(1- p )}{n } } [/tex]

=>    [tex]\sigma  =  \sqrt{ \frac{0.64(1- 0.64 )}{ 50} } [/tex]

=>    [tex]\sigma  =  0.068  [/tex]

Generally the probability that the value of [tex]\^ p[/tex] will be between 0.54 and 0.61 is mathematically represented as

     [tex]P(0.51 < \^ p < 0.61 ) = P( \frac{0.5 4 - \mu_{x}}{\sigma } < \frac{\^ p- \mu_{x}}{\sigma } < \frac{0.6 1 - \mu_{x}}{\sigma } )[/tex]

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

 [tex]P(0.51 <  \^ p <  0.61 ) =  P( \frac{0.5 4  - 0.64}{0.068 } < Z < \frac{0.6 1  - 0.64}{0.068} )[/tex]

     [tex]P(0.51 <  \^ p <  0.61 ) =  P(-1.470 < Z < -0.4412 )[/tex]

=>   [tex]P(0.51 <  \^ p <  0.61 ) =  P( Z < -0.4412 ) - P(Z <  -1.470 ) [/tex]

From the z table  the probabilities of  ( Z < -0.4412 ) and (Z <  -1.912 ) is

     [tex]P ( Z < -0.4412 )  = 0.32953 [/tex]

and  

    [tex]P(Z < -1.470 ) = 0.070781[/tex]

Generally

   [tex]P(0.51 <  \^ p <  0.61 ) =  0.32953 -0.070781 [/tex]

  [tex]P(0.51 <  \^ p <  0.61 ) =  0.2587 [/tex]

Generally the probability that the value of [tex]\^ p[/tex] will be greater than 0.71  is mathematically represented as

        [tex]P(\^ p > 0.71 ) = P( \frac{\^ p - \mu_{x}}{\sigma} > \frac{0.71 - 0.64 }{ 0.068 } )[/tex]

=>    [tex]P(\^ p > 0.71 ) = P( Z > 1.0294 )[/tex]

From the z table  the probabilities of ( Z >   1.0294  )

      [tex]P( Z > 1.0294 ) = 0.15165[/tex]

So

  [tex]P(\^ p > 0.71 ) = 0.15165[/tex]

Answer:

The probability that the shopping time will be between 25 and 30 minutes is 0.25.

Step-by-step explanation:

The question is:

What is the probability that the shopping time will be between 25 and 30 minutes?

Solution:

Let X represent the time spent shopping at a supermarket for a basket with 20 specific items.

It is provided that X follows Uniform (20, 40).

Compute the probability that the shopping time will be between 25 and 30 minutes as follows:

[tex]P(25<X<30)=\int\limits^{30}_{25} {\frac{1}{40-20}} \, dx[/tex]

                         [tex]=\int\limits^{30}_{25} {\frac{1}{20}} \, dx \\\\=\frac{1}{20}\times [x]^{30}_{25}\\\\=\frac{30-25}{20}\\\\=0.25[/tex]

Thus, the probability that the shopping time will be between 25 and 30 minutes is 0.25.

Answer:

B.30

Step-by-step explanation:

Make a table and do ten divided by 10 to get 1 and divide 6 by 10 to get 0.6 then do 18 divided by 0.6 to know what to multiply by to get to eighteen which ends up being 30

Answer:

Length = [tex]13\ \text{ft}[/tex]

Width = [tex]7\ \text{ft}[/tex]

Step-by-step explanation:

Let

Breadth of the garden = x

According to the question length of the garden = 6+x

Fencing given for the rectangular garden = 27 ft

Perimeter of the garden is given by

[tex]6+x+x+x=27\\\Rightarrow 6+3x=27\\\Rightarrow x=\dfrac{27-6}{3}\\\Rightarrow x=7\ \text{ft}[/tex]

Here the garden's length will be along the garage so fencing will not done there. So length will be added only once in the perimiter.

The length of the garden is [tex]6+7 = 13\ \text{ft}[/tex] and the width is [tex]7\ \text{ft}[/tex].

Answer:

x=5/3 or 1 and 2/3

Step-by-step explanation:

8x+(-6)=5x-1

8x+(-6)+6=5x-1+6

8x=5x+5

8x-5x=5x-5x+5

3x=5

3x/3=5/3

x=5/3 or 1 2/3

Answer:

the absolute value of 5 is 5 and absolute value of -5 is also 5.

Step-by-step explanation:

the absolute value of a number refers to how many spaces away a number is from 0, so it doesn't matter if the number is positive or negative, the absolute value is always positive. the absolute value of -7 is 7, the absolute value of 24 is 24, the absolute value of -435,706 is 435,706, the absolute value of 1,234,567,890 is 1,234,567,890.

Answer:

Step-by-step explanation:

it is correct

Answer:

0.4919

Step-by-step explanation:

From the given data:

187 of the 368 people killed by lightning were men.

i.e

Number of men = 187

Total number of people killed = 368

The objective is to determine the probability that the person killed by lightning is a woman.

The number of women = 368 - 187

The number of women  = 181

The probability that the person killed by lightning is a woman = 181/368

= 0.4919

Answer:

Interest earned = $146,196.75

Step-by-step explanation:

A = $175,000

r = 3.2% = 0.032

n = 19

m = 12

FV = A*(1+i/m)^nm

FV = 175,000*(1+0.032/12)^19*12

FV = 175,000*(1+0.002667)^228

FV = 175,000*(1.002667)^228

FV = 175,000*1.83541

FV = $321196.75

Interest earned = $321,196.75 - $175,000

Interest earned = $146,196.75

Answer:

$20

Step-by-step explanation:

First, we need to find 20% of $25. You can do this by multiplying $25 by 0.2

After multiplying , you get $5. So 20% of 25 is 5.

Now, we subtract because the shoes are 20% off

25 - 5 = $20

====================================================

Explanation:

We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.

Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.

The probability we're after is A/B = 6/7 = 0.8571

Answer:

3.65 meters

Step-by-step explanation:

If the rope is 3.65 meters long, then the goat can only go as far as the rope is long. That's unless the goat eats the rope.

The maximum area that a goat can graze on will be the area of a circle where the center of the circle will be one end of the rope as shown in the attached diagram.

The area of a circle with radius r is πr².

Radius of the circle= length of the rope = 3.65m

So, area of the circle = [tex]\pi r^{2}[/tex]

Area of the circle = [tex]\pi 3.65^{2}[/tex]

Area of the circle = 41.85m².

Therefore, the maximum area of grass that the goat can graze on is 41.85 m²

Answer:

associative, distributive, commutative

Step-by-step explanation:

Commutative is something just flipped around so the 3rd equation would be commutative. Associative is something with the same numbers but asked in a different way so 1st would be associative. Distributive is breaking the equation down and apart to make it easier to complete so the 2nd would be distributive.

Answer:

y = 1/2x + 8

Step-by-step explanation:

The 8 is where the line passes through the y-coordinate, and the 1/2x is the slope of the line. The 8 is positive because the line passes through +8 and not -8.

Whats the question???

What is the question?

Answer:

1. 4:5

2. 1/5

Divide the numbers 24 & 30.

24 ÷ 6 = 4

30 ÷ 6 = 5

Put together in a ration.

4:5

Add the numbers 24 and 30.

You get 54, right?

See how many times 54 goes into 330.

It goes into 330 5 times.

So, the fraction would be 1/5.
