Answer:

see below

Step-by-step explanation:

What is the theoretical probability that the family has two dogs or two cats? (1/2)

The choices are dd, dc, cd, cc

There are 4 choices = dd or cc/ total = 2/4 = 1/2

Let the heads of the coin be dogs and the tails of a coin be cats

Flip two coins and coin A is the first pet and coin B is the second pet

heads , heads = 10

heads, tails 14

tails heads =13

tails tails = 13

total 50

Experimental probability 2 dogs or 2 cats = ( hh, tt) /total = ( 10+13) /50 = 23/50

If we had 3 pets

what is the theoretical probability that they have three dogs or three cats?

ddd, ddc, dcd, dcc, ccc, ccd ,cdc, cdd

There are 8 options

ddd or ccc/ total = 2/8 = 1/4

Let the heads of the coin be dogs and the tails of a coin be cats

Flip three coins and coin A is the first pet and coin B is the second pet Coin C be the third pet

At a local store you find the following prices listed:

Softa [21]

Hello!

Find the cost of each individual item.

1.28 / 2 = 0.64

Each roll of tape costs $0.64.

0.87 / 3 = 0.29

Each notebook costs $0.29.

Each highlighter costs $1.59.

1.98 / 2 = 0.99

Each pen costs $0.99.

One roll of tape is $0.64, two notepads are $0.58 two highlighters cost $3.18, two pens are 1.98.

Add them up: .

0.64 + 0.58 + 3.18 + 1.98 = 6.38

ANSWER:

You would pay B. $6.38.

Answer:

The length between the two points is RT = 1.3 units

Step-by-step explanation:

The coordinates of the point R and T are R(2,1.2) and T(2,2.5).

Now, by DISTANCE FORMULA:

The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:

$PQ = \sqrt{(a-c)^2 + (b-d)^2}$
