Heads is a bird, and tails is a fish. After flipping the coins 100 times, the coins where it is double heads or double tails, whichever one had the most is the one that they would buy.

What a weird way to buy a pet. Anyways, hope I helped. :)

a) 3 goals

The median is the middle number of a data set. The best way to find the median is to list out all of the goals (and their frequencies!) and cross off numbers from the outside in until we find the median, or middle number.

0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4

1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4

1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4

1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3

1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3

2, 2, 2, 2, 3, 3, 3, 3, 3, 3

2, 2, 3, 3, 3, 3

3, 3

The median is 3 goals.

b) 2.33 goals

To find the mean, we add up all of our listed numbers below and divide by the total number of terms we added together.

0(2) + 1(8) + 2(4) + 3(10) + 4(6) = 70

total number of terms = 2 + 8 + 4 + 10 + 6 = 30

70 / 30 = 2.33

The mean number of goals conceded was approximately 2.33.

Hope this helps! :)

The original cost of a necklace is $32. The jewelry store is having a sale and every item is 30% off. A 6.75% tax rate is charge

madam [21]

Answer:

Step-by-step explanation:

Original cost = $32

Discount = 30% of 32

$=\frac{30}{100}*32\\\\=\frac{3*32}{10}\\\\=\frac{96}{10}\\\\=9.6\\$

Selling price = 32 - 9.60 = $22.40

Tax = 6.75% of 22.40

$=\frac{6.75}{100}*22.40\\\\= 1.512$

= $ 1.51

Total cost with discount and tax = 22.40 - 1.51 = $ 20.89

Given a≠±b and a^2−b^2/a+b =12, find a−b.

11Alexandr11 [23.1K]

$\dfrac{a^2 - b^2}{a+b} = 12$

--------------------------------------------------
Factorise a² - b² :
--------------------------------------------------
$\dfrac{(a+b)(a-b)}{a+b} = 12$

--------------------------------------------------
Crossed out common factors, (x + a) :
--------------------------------------------------
$a- b = 12$
