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:

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.

Complete Question

The complete question is shown on the first uploaded image

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]

y-intercept=0

Step-by-step explanation:

I hope this helps... if it does, may I be brainliest???

Answer:

b=4

Step-by-step explanation:

For this question we need to know the formula of slope that is m which is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where [tex](x_1,y_1) , (x_2,y_2)[/tex] are the points [tex](5,-8),(-1,b)[/tex] respectively

and hence we have the value of m= -2 which is the slope we simply plug in all the values.

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\-2=\frac{b-(-8)}{-1-5} \\\\-2=\frac{b+8}{-6} \\\\12=b+8\\12-8=b\\4=b[/tex]

So the value of b=4

Answer:

b is 4

Step-by-step explanation:

Several steps are required to find this answer. You need to use the information you are given as well as the formula y=mx+b. You are given the slope and one of the coordinates. Plug the information into the formula to find b, which is the constant.

The point given is (5,-8)

The slope given is -2

Plug the x and y into y=mx+b

-8=-2(5)+b

-8=-10+b

-8+10=b

b=2

Now that you have the full equation, y=-2x+2 , you can plug in the x-coordinate of the other coordinate to find the missing y-value.

y=-2(-1)+2

y=2+2

y=4

Therefore, the b you are solving for is 4.

Answer:

(1) 0 and 1

(2) Correct option D

Step-by-step explanation:

It is provided that pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute.

Let X denote the pulse rates of women.

(1)

Let us consider a random variable, X that follows N (µ, σ²), then [tex]Z=\frac{X-\mu}{\sigma}[/tex], is a standard normal variate with mean, E (Z) = 0 and variance V (Z) = 1.

That is, Z follows N (0, 1).

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Thus, z-scores are a type of standardized scores.

The values of the mean and standard deviation after converting all pulse rates of women to z scores are 0 and 1 respectively.

(2)

The z scores are numbers without units of measurement.

What is the question?

Answer:

x > 3

Step-by-step explanation:

Answer:

x > 3

Step-by-step explanation:

Step 1:

8x - 6 > 12 + 2x         Equation

Step 2:

6x - 6 > 12        Subtract 2x on both sides

Step 3:

6x > 18          Add 6 on both sides

Step 4:

x > 18 ÷ 6      Divide 6 on both sides

Answer:

x > 3

Hope This Helps :)

The standard normal distribution has a cumulative distribution function (probability that the random variable, in this case the temperature, is less than a given number) well-known as erf, and the probability of [tex]T\in[-2.21,-1.52][/tex] is [tex]erf(-1.52)-erf(-2.21)\approx 0.0298109[/tex] (found using WolframAlpha)

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:

23 to the power of 7

Step-by-step explanation:

it is correct

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.

Hope this helps you!
