If it takes 930 kg of food to feed a pair
of elephants for 3 days, how much food
would you need to feed them for a week?

Answer:  see below

Step-by-step explanation:

I'm not sure exactly what you are asking for but here is what the box plot tells you:

Minimum is 17 items.

Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.

Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.

Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.

Maximum is 62 items.

The data is "heavier" on the right so it is skewed left.

Range is 62 - 17 = 45

IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13

Answer: x = 13/2

Step-by-step explanation:

Distribute: 4(x - 2) = 18

4x - 8 = 18

Add 8 to both sides

4x - 8 + 8 = 18 + 8

Simplify:

4x = 26

Divide both sides of the equation by the same term

4x = 26

4x/4 and 26/4

Cancel term that are both in the numerator and denominator

Divide the numbers

X = 13/2

Answer:

The 90% confidence interval is  [tex] 2.47<\mu < 2.59 [/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  6

   The sample mean is  [tex]\= x = 2.53 \ mm[/tex]

   The standard deviation is  [tex]\sigma  =  0.090\ mm[/tex]

Given that the confidence level is 90% then the level of significance is  

        [tex]\alpha =  (100 - 90)\%[/tex]

=>     [tex]\alpha =  0.10 [/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645 [/tex]

Generally the margin of error is mathematically represented as  

      [tex]E =1.645 *  \frac{0.090 }{\sqrt{6} }[/tex]

=>   [tex]E = 0.060 [/tex]

Generally 90% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

      [tex]2.53  -0.060 <\mu < 2.53  + 0.060[/tex]

=>   [tex] 2.47<\mu < 2.59 [/tex]

Answer:

[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x = \frac{1}{3} ( x - 1)\\\\ \\\frac{4}{3}x - \frac{4}{3} - \frac{2}{3} = \frac{4}{3} ( x - 1)\\\\( \frac{1}{3} x + \frac{2}{3} ) + ( -\frac{2}{3}x - \frac{4}{3}) = -\frac{1}{3} ( x + 2)\\\\(\frac{2}{3}x + \frac{1}{3} ) + (\frac{2}{3} x - \frac{2}{3} ) = \frac{1}{3} ( 4x - 1 )[/tex]

Step-by-step explanation:

Simplify each equation by combining like terms, and then factoring

[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x[/tex]

= [tex]\frac{1}{3} x + \frac{1}{3}[/tex]

Answer:

Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg

Step-by-step explanation:

22.5 is 1/3 of 67.5

so compliment is 67.5.

Supplement is just adding another angle so I chose 7.

I did 22.5 x 7 = 157.5

Another example would be:

Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Answer:

[tex]A = 34\frac{1}{3}[/tex]

[tex]B = 72\frac{2}{3}[/tex]

[tex]C = 73[/tex]

Step-by-step explanation:

Given

Shape: Triangle

[tex]B = 4 + 2A[/tex]

[tex]C = 3A - 30[/tex]

Required

Solve for A, B and C

Since the shape is a triangle,

[tex]A + B +C = 180[/tex]

Substitute [tex]B = 4 + 2A[/tex] and [tex]C = 3A - 30[/tex] in [tex]A + B +C = 180[/tex]

[tex]A + 4 + 2A + 3A - 30 = 180[/tex]

Collect Like Terms

[tex]A + 2A + 3A = 180 + 30 - 4[/tex]

[tex]6A = 206[/tex]

Solve for A

[tex]A = 206/6[/tex]

[tex]A = 34\frac{1}{3}[/tex]

Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]B = 4 + 2A[/tex]

[tex]B = 4 + 2 * 34\frac{1}{3}[/tex]

[tex]B = 4 + 2 * \frac{103}{3}[/tex]

[tex]B = 4 + \frac{206}{3}[/tex]

[tex]B = \frac{12 + 206}{3}[/tex]

[tex]B = \frac{218}{3}[/tex]

[tex]B = 72\frac{2}{3}[/tex]

Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]C = 3A - 30[/tex]

[tex]C = 3 * 34\frac{1}{3} - 30[/tex]

[tex]C = 3 * \frac{103}{3} - 30[/tex]

[tex]C = 103 - 30[/tex]

[tex]C = 73[/tex]

Answer:

There's a proportion relationship between number of shell and their cost

Step-by-step explanation:

The graph is not given.

However, I've added the appropriate graph as an attachment.

From this, point....

I'll show that the cost and number of shells as given in the question are proportional.

Represent cost with y and number of shells with x

x = 2 when y = 0.8

x = 3 when y = 1.2

x = 4 when y = 1.6

Divide each value of y by x to get the constant of proportion (r).

r = y/x

r = 0.8/2 = 0.4

r = 1.2/3 = 0.4

r = 1.6/4 = 0.4

Notice that the values of r remain constant.

Hence, there's a proportion relationship between both

And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.

Given :

The following steps can be used to determine there is a proportional relationship or not between the number of shells and their cost:

Step 1 - First determine the value of x and y from the given data.

Points - (2,0.8), (3,1.2), and (4,1.6)

Step 2 - Now, divide y by x in order to determine the proportionality constant.

[tex]r = \dfrac{0.8}{2} = 0.4[/tex]

[tex]r'=\dfrac{1.2}{3}=0.4[/tex]

[tex]r" =\dfrac{1.6}{4}=0.4[/tex]

Step 3 - Observe that the values of r, r', and r" are the same. Therefore, there is a proportional relation between them.

The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.

Answer:

The input value is -2

Step-by-step explanation:

Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).

What we are simply asked to do is to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.

Thus, when y = 2 on the x-axis, x = -2 on the x-axis.

The input value of -2, corresponds to the output value of 2.

Answer:

-2

Step-by-step explanation:

Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).

We are expected to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.

When y = 2 on the x-axis, x = -2 on the x-axis.

The input value of -2, corresponds to the output value of 2.

Answer:

a) The mean cost of the 25 trips is:

$12.35.

b) The standard deviation of the cost of the 25 trips is:

$52.50

Step-by-step explanation:

a) Data and Calculations:

Initial fee (fixed) = $2.55

Variable (additional) charge = $1.75 per mile

Equation = 2.55 + 1.75(miles)

Trips = 25

Mean distance for first 25 rides = 5.6 miles

Standard deviation = 1.2 miles

Mean cost of the 25 trips = 2.55 + 1.75 (5.6) = $12.35

Total cost = $308.75 (25 * 12.35) based on mean cost

Standard deviation of the cost of the 25 trips:

Total standard deviation for the 25 trips = 30 miles (1.2 * 25)

= $52.50 (1.2 * 25 * $1.75)
