You and two friends visit a pizza shop. there are 15 toppings. 5 toppings are meat and the rest are vegetable. each of you order a different topping (no repeats) at random. what is the probability that your group orders only meat toppings?

Step-by-step explanation:

There are 15 toppings: 5 toppings are meat and 10 toppings are vegetable.

You and two friends form a group of 3 people.

Find the number of choices 3 different meat toppings:

Find the number of choices 3 different toppings:

Hence, he probability that your group orders only meat toppings is

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
