Answer: x*(x-5)

Step-by-step explanation:

Plexiglass is a cuboid

which means that the area would be l*w

in the question it states that the width is 5 cm shorter than the length

since we dont know the values

we represent them as x

so using l*w

we write x*(x-5)

Answer:

There no sufficient evidence to support the manufactures claim at the 0.05 level

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 22100 \ miles[/tex]

    The  sample mean is [tex]\= x = 23400 \ miles[/tex]

   The  sample size is  [tex]n  = 18[/tex]

   The standard deviation is [tex]\sigma  =  1 500 miles[/tex]

    The test statistics is  [tex]t = 3.677[/tex]

    The level of significance is [tex]\alpha  =  0.05[/tex]

The null hypothesis  is  [tex]H_o :  \mu =  22100[/tex]

The  alternative hypothesis  is  [tex]H_a :  \mu  \ne 22100[/tex]

Generally the p-value  is mathematically represented as

     [tex]p-value  =  2 *  P(t >3.677 )[/tex]

From the z-table  [tex]P(t >3.677 )  =  0.000118[/tex]

So

    [tex]p-value  =  2 *  0.000118[/tex]

=> [tex]p-value  =  0.000236 [/tex]

From he value given and obtained we see that  [tex]p-value  <  \alpha[/tex]

Hence we reject the null hypothesis

Hence there no sufficient evidence to support the manufactures claim

Answer:

18

Step-by-step explanation:

1. Create the ratio 12:9

The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.

2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)

3. Add 9 to 9. (18)

We now have 21:18.

Answer:

profits will increase so with that being said the supply of them dropped if demand increased getting bikes will be harder for competing business in the area and so therefore if you have 200 bikes and others have 50 bikes your gonna make way more profit and for the people with 50 bikes they will gain and lose profits because when they run out of bikes they have to buy more and they are more expensive because of the demand on them

Step-by-step explanation:

The explanation regarding the change of price that impact the profits should be explained below.

The profit should rise when the supply should fall. In the case when I have 200 bikes while the other should have 50 bikes so here I make more profit however the other people will gain but the profit should be lost since the bikes should be out of the stock and at the same time they need to buy more that should be more expensive due to the demand.

total time taken = 40 min

let x be the total length/ distance of the journey.

speed(v) = distance/ time

100= (1/2 x)/ time ---1

60= (1/2 x)/ time ---2

add 1 and 2

160= x/40

where 40 is the total time taken

44.44m/s= x/ 2400s (i converted the speed and time)

x = 106,656 metres = 106.656km

the total length is 106.656 km.

Let's assume the total length of the journey is "x" km. Since the journey took 40 minutes to complete, we first need to convert this time to hours, which is [tex]40/60 = 2/3 h[/tex] hours.

According to the information given, the first half of the journey was traveled at an average speed of 100 km/h, which means the distance covered during this time is (1/2)x km. The time taken for this is given by [tex](1/2)x / 100 = x/200[/tex] hours.

Similarly, the second half of the journey was traveled at an average speed of 60 km/h, which means the distance covered during this time is (1/2)x km.

The time taken for this is given by [tex](1/2)x / 60 = x/120[/tex]hours. Now, we can add the times taken for both halves, which gives us [tex]x/200 + x/120[/tex]hours [tex]= 2/3[/tex]hours. By solving this equation, we arrive at [tex]x = 240 km.[/tex]

Therefore, the total length of the journey is 240 km.

Step-by-step explanation:

You can use the formula for slope (m) to find it:

Answer:

0.17

Step-by-step explanation:

From the question, we know that

A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.

Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.

To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have

Standard Deviation, S = 1.9101 / √125

Standard Deviation, S = 1.9101 / 11.18

Standard Deviation, S = 0.17

Therefore, the Standard Deviation is 0.17

Answer:

The values are

      [tex]\mu_{\= x } = \mu = 4.10[/tex]

And

      [tex]\sigma _{\= x} = 0.38202[/tex]

Step-by-step explanation:

The  population mean is  [tex]\mu = 4.10[/tex]

 The  standard deviation is  [tex]\sigma = 1.9101[/tex]

  The sample size is  n  =  125 students

Generally the mean of the sampling distribution of the sample mean is equivalent to the population mean

  i.e  [tex]\mu_{\= x } = \mu = 4.10[/tex]

Generally the standard deviation of the sampling distribution of the sample mean alcohol consumption is mathematically represented as

      [tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]\sigma _{\= x} = \frac{1.9101 }{\sqrt{125} }[/tex]

=>    [tex]\sigma _{\= x} = 0.38202[/tex]

Answer:

1620

Step-by-step explanation:

180/2=90

90*18=1620

You buy milk with 180 calories in two glasses. Now compute the caloric value of 18 cups. 18 cups contain 1620 calories.

Therefore,

You buy milk with 180 calories in two glasses.

Now compute the caloric value of 18 cups.

Let 18 cups have a calorie count of As, and 2 cups have 180 calories.

A serving of two cups contains 180 calories.

As a result, the ratio would be 2: 180.

As a result, 18 cups contain X calories.

18 cups are equal to X calories.

Consequently, the ratio would be  X : 18

We now set a ratio to determine how many calories are in 18 cups:

2 : 180  ::  18  : X

Simplifying,

2/ 180 = 18/X

Cross multiplying results in:

2X = 18 × 1 80

= 3240

By multiplying both sides by 2, we obtain:

X = 3240/2

= 1620

Hence, 18 cups have 1620 calories in them.

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.25 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 36

.a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 36

The value of the mean is

μ=___ peas.

The value of the standard deviation is

σ=___peas.

b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.

Values of ___ peas or fewer are significantly low.

Values of ___ peas or greater are significantly high.

c. Is a result of 2 peas with green pods a result that is significantly low? Why or why not?

The result (is, is not) significantly low, because 2 peas with green pods is (greater than, equal to, less than) peas.

Answer : A) mean : 9,  std = 2.6

               B) significantly low value : = 3.8, significantly high value = 14.2

C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods

Step-by-step explanation:

given data :

probability ( p )= 0.25

number of groups ( n )= 36

A ) i) Mean of the of the peas ( u )

u = np = 36 * 0.25 = 9

ii) standard deviation of the peas ( б ) = [tex]\sqrt{np(1-p)} = \sqrt{9(1-0.25)}[/tex]  = 2.60

B) Using the range rule of thumb to find the values separating results that are significantly low or significantly high.

note : assuming z = 2 and error = 5%

i) The values that are significantly lower

u - zб = 9 - (2*2.6 )

         = 3.8

ii) The values that are significantly higher

u + zб = 9 + (2*2.6)

          = 14.2

C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods
