Answer:

-12r + 8s

Explanation:

Since there is a subtraction sign in front of 16r, to combine it with 4r, it must be subtracted, resulting in -12 r (to subtract a greater number from a smaller number, subtract the smaller number from the greater number and make it negative). Since there is an addition sign in front of 3s, to combine it with 5s, the two must be added. 5s + 3s = 8s. When combined, the result is -12r + 8s.

9 ft. 15 ft The volume of the figure is cubic feet. 15 ft. 15 ft​

Answers

Answer:

4,050 cubic feet

Step-by-step explanation:

The figure is made up of a square pyramid and cube

Therefore:

Volume of the figure = volume of the square pyramid + volume of the cube

✔️Volume of the square pyramid = ⅓*a²h

a = 15 ft

h = 9 ft

Volume of square pyramid = ⅓*15²*9 = 675 ft³

✔️Volume of the cube = s³

s = 15 ft

Volume of the cube = 15³ = 3,375 ft³

✔️Volume of the figure = 675 + 3,375 = 4,050 cubic feet

A bakery in Hong Kong regularly orders carton of cranberries from Australia. The net weight (in ounces) of

cranberries of a random sample of 20 cartons were as follow:

160 170 170 190 210 240 240 240 270 280

290 290 300 420 500 520 530 610 630 650



(c) The bakery orders the cranberries from Australia with currency exchange rate of AUD 1 to HKD 5.8.

For each ounce of Australia cranberries costs AUD 2 and the fixed shipping fee of each carton is HKD

80. Find the mean, standard deviation, range, and third quartile of the payment (in HKD) of ordering a

carton of cranberries from Australia to Hong Kong.

Answers

Answer:

i) Mean = 1933.1817

ii) Range = 5684

iii) Third quartile = 6054

Step-by-step explanation:

Given data :

currency exchange rate : 1 AUD = 5.8 HKD

cost of each ounce = 2 AUD

Fixed shipping cost for each carton = 80 HKD

number of cartons = 20

next determine the total cost of the 20 cartons in HKD

= ∑(weight in ounce * cost of each ounce *exchange rate) +fixed shipping cost

= ∑ ( 160*2*5.8 + 80 )  + -------------- + (650 *2*5.8 + 80 ) ----------------- ( 1 )

= 81756 HKD

i) find the mean value ( X )

= Total cost / number of cartons

= 81756 / 20 = 4087.8

ii) Find the standard deviation

= [tex]\sqrt{\frac{(1936-4087.8)^2+-----+(7620-4087.8)^2}{20-1} }[/tex]      note: std =  √∑(xi-X )^2 / (n-1)

= 1933.1817

iii) Find the range

Range = highest cost - lowest cost   ( values gotten from equation 1 )

           = 7650 - 1936

           = 5684

iv) Determine the third quartile

third quartile = 6054

Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:

Answers

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

[tex]\hat{y}=mx+b[/tex]           ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

[tex]m\approx 2.55,b\approx -6.435[/tex]

Substitute these values in (i).

[tex]\hat{y}=(2.55)x+(-6.435)[/tex]

[tex]\hat{y}=2.55x-6.435[/tex]

Therefore, the correct option is A.

The graph of regression line is attached below.

The equation of regression line is [tex]y=2.55x-6.435[/tex]

Equation of regression line:

A graphing calculator is a calculator device that has the ability to display plotted graphs for complex equations.

First we have to enter the given table in graphing calculator,

After entering the data given into table,

We get,   m= 2.55  and b= -6.435

So that, the equation of regression line is [tex]y=2.55x-6.435[/tex]
