A deep sea exploring ship is pulling up a diver at the rate of 20 feet per minute. The diver is a hundred feet below sea level. How deep was the diver 3 minutes ago?

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:

Clarence is 5 inches taller.

42-37=5

Answer:

Clarence is 5 inches taller.

Step-by-step explanation:

You are using subtraction by doing 42-37

42-37 cross out the 4 to be a 3, make the 2 a 12 and subtract 12-7=5

3-3 is 0 so it would be 5.

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:

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 4th one that looks like a squiggle

Step-by-step explanation:

The answer to this is -4

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!

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.

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]

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:

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:

It would be 13.

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:

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.
