Answer:

This distribution should be expected to be right skewed.

Step-by-step explanation:

Pearson skewness:

The skewness of a data set is given by the subtraction of the mean by the mode, divided by the standard deviation.

If the coefficient is positive, the distribution is right skewed.

If the coefficient is negative, the distribution is left skewed.

If the coefficient is sufficiently close to 0(+/- 0.05), the distribution is bell shaped.

In this question:

Mean 7.4, mode 4, standard deviation 11

(7.4-4)/11 = 3.4/11 = 0.31

Positive coefficient, so right skewed.

Answer:

25 in by 45 in.

Step-by-step explanation:

The length of the box will be x + 20 - 10 - 10 = x

The width of the box will be x - 10 - 10 = x - 20

The height of the box will be 10

So the volume = length x width x height

                        = x(x - 20)10 = 1250

                        =   [tex]10x^{2} - 200x = 1250[/tex]

                         [tex]10x^{2} -200x - 1250 = 0[/tex]

                           [tex]10(x^{2} -20x - 125)\\[/tex] = 0

                          10(x + 5)(x - 25) =0

                                 x = -5      x = 25

- 5 must be discarded since a length cannot be negative.  

Therefore x = 25 in = width of piece of cardboard

            x + 20 = 25 + 20 = 45 in = length of piece of cardboard

Answer:

1 hr 45 min

Step-by-step explanation:

so to get one from 2/7 me multiply by 7/2

so if we also multiply the time by 7/2

we get 1/2*7/2=7/4 hour

1 and 3/4 hour or

1 hr 45 min

Answer:

1hour 45 minutes

Step-by-step explanation:

2\7= 30min

7\7=7\7×30÷2\7=7\7×30×7\2=105mins

1h=60min

   =105min

Answer:

A cold water tap takes 3 minutes to fill the bath. A hot water tap takes 2 minutes to fill the bath. How long does it take to fill the bath when both taps are open at the same time?

It is easiest just to let the bath be a given size.

My little bath will be 12 litres

cold water  4L/min          hot water = 6L/min      

together 10L/1 min

10*(12/10) L per  1*(12/10) minutes

12L per 1.2min

12L per 1min and 12sec

It will take 1 minute and 12 seconds to fill the bath.

Step-by-step explanation:

Answer:

It will take 5 minutes for both faucets together to fill the water cooler

Step-by-step explanation:

I'm kinda just guessing but I do have a reasonable explanation

So the average time it takes for the faucets INDIVIDUALLY to fill the water cooler is 10 minutes

But since both faucets are filling them TOGETHER, it should take half the time

And half of 10 is 5

So it should take 5 minutes for both faucets together to fill the water cooler

If that makes sense

Please read down below, thanks

Step-by-step explanation:

Vertical angles are always equal.

Because the two expression we have are equal, we can make the equation:

4x + 2 = 5x - 13

Let's move x to one side and the constants to the other side.

Subtract both sides by 4x and add both sides by 13

15 = x

Now we know x = 15, we can solve for the angles.

∠ABC is 4x + 2 so: 4(15) + 2 = 47 degrees

∠CBE added up with ∠ABC is 180 degrees so: 180 - 47 = 133 degrees

∠DBE is the same as ∠ABC so: 47 degrees

∠ABD is also the same as ∠CBE so: 133 degrees

Using an exponential function, it is found that the population will be of 350 students in the year of 2039, 34.3 years after 2005.

An increasing exponential function is modeled according to the rule presented as follows:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which the parameters of the equation is defined as follows:

In the context of this problem, the values of the parameters are given as follows:

Hence the equation for the number of students in t years after 2005 is given as follows:

[tex]A(t) = 127(1.03)^t[/tex]

The number will be of 350 students when A(t) = 350, hence:

[tex]A(t) = 127(1.03)^t[/tex]

[tex]350 = 127(1.03)^t[/tex]

[tex](1.03)^t = \frac{350}{127}[/tex]

[tex]\log{(1.03)^t} = \log{\left(\frac{350}{127}\right)}[/tex]

[tex]t\log{1.03} = \log{\left(\frac{350}{127}\right)}[/tex]

[tex]t = \frac{\log{\left(\frac{350}{127}\right)}}{\log{1.03}}[/tex]

t = 34.3 years.

34.3 years = during the year of 2005 + 34.3 = 2039. This result is shown by the graph at the end of the answer.

The problem asks for when the population will be of 350 students.

Answer:

Volume of the figure = 64 cm³

Step-by-step explanation:

Volume of the given figure = Volume of complete cuboid - volume of the cuboid having one face as ABCD

Volume of complete cuboid = Length × Width × Height

                                               = 10 × 2 × 6

                                               = 120 cm³

Volume of the part having one face as ABCD = AB × BF × BC

                                                                            = 7 × 2 × (6 - 2)

                                                                            = 56 cm³

Volume of the given figure in the picture = 120 - 56

                                                                    = 64 cm³

Therefore, volume of the figure = 64 cm³

Step-by-step explanation:

(15x + 5) and (-2 + 16x) represents the measures of corresponding angles.

Measures of corresponding angles are equal.

Therefore,

Answer:

The slope is 2

Step-by-step explanation:

its 6/3 and if you simplify that its 2

First, you replace c and d. You would end up with[tex]\frac{1}{4}[/tex] (6) + 3(7).

Then, you evaulate it. You end up with [tex]1\frac{1}{2}[/tex] + 21.

Lastly, you add them together. The final answer is [tex]22\frac{1}{2}[/tex].

Hi there!

Simplifly c and d:

c=6, d=7

Multiply terms by terms:

[tex]\frac{1}{4}[/tex]·[tex]6=1\frac{2}{4}[/tex]

[tex]3[/tex]·[tex]7=21[/tex]

Add all terms together:

[tex]1\frac{2}{4}+21=22\frac{2}{4}[/tex]

Simplifly terms:

[tex]22\frac{2}{4}=22\frac{1}{2}[/tex]

Answer:

121

Step-by-step explanation:

Find out the amount of units Ismail have more than Johan.

11 - 7 = 4 units

Since Ismail has 44 more sweets than Johan and 4 more units..

4 units = 44

1 units = 44 ÷ 4 = 11

Altogether, there's 11 units.

11 units = 11 x 11 = 121
