A company makes muesli which contains nuts and sultanas.

They counted the number of nuts in 50 individual serving packets.

They drew a table.

Number     Midpoint   Number of            

of nuts         (x)           packets (f)              f.x  

4 - 6               5                3                      15

7-9                 8                9                          

10 - 12           11                 12                      

13 - 15            14                17                          

16 - 18            17                 9                    

                                     50                    

To Find :

complete the table

calculate and estimate for the mean

The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:

Number of Nuts Number of Packets Midpoint (x) fx

4-6 5 5 5 * 3 = 15

7-9 8 8 8 * 9 = 72

10 - 12 11 11 11 * 12 = 132

13 - 15 14 14 14 * 17 = 238

16 - 18 17 17 17 * 9 = 153

Total 50  610

b) To calculate an estimate for the mean, we use the formula:

Mean = Sum of (fx) / Total Number of Packets

Mean = 610 / 50

Mean ≈ 12.2

Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

Answer:

14508 if I'm wrong I'm sorry

Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Answer:

  (c)  (6x^4 – 4)(36x^8 + 24x^4 + 16)

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

  (a^3 -b^3)

is ...

  (a -b)(a^2 +ab +b^2)

__

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

  a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

Answer:

$160

Step-by-step explanation:

Let the original cost of suit be x

If the suits were sold for $72 each and this price was 45% of a suit's original price, then;

72 = 45% of x

72 = 0.45x

x = 72/0.45

x = 160

Hence the original price of the suit is $160

Answer:

C

Step-by-step explanation:

C will have the least value with -99.

A would be 1/100, which is 0.01, which is small, but larger than -99.

B would be 10/100, which is 0.1, which is larger than A.

C is 1-100, which equals -99.

D is 10-100, which equals -90. -99 is smaller than -90.

Answer:

c) 1 - x

Step-by-step explanation:

x = 100

a) [tex]\frac{1}{x}[/tex] ⇒ [tex]\frac{1}{100}[/tex]

answer ⇒ 0.01

b) [tex]\frac{10}{x}[/tex] ⇒ [tex]\frac{10}{100}[/tex]

answer ⇒ 0.10

c) 1 - x ⇒ 1 - 100

answer ⇒ -99

d) 10 - x ⇒ 10 - 100

answer ⇒ -90
