Answer:

Lowest Price - Store B

Middle Price - Store C

Highest Price - Store A

Step-by-step explanation:

Store A Price - $22.50

25 x 0.1 = 2.5

25 - 2.5 = 22.5

Store B Price - $21.60

27 x 0.2 = 5.4

27 - 5.4 = 21.6

Store C Price - $22.1

26 x 0.15 = 3.9

26 - 3.9 = 22.1

Answer:

Rob saved $30 to buy new Mp3 player.

Step-by-step explanation:

Given:

Rob is saving money to buy a new Mp3 player.

For every $14 earned he saved $5.

For 14 dollars earned = Money Saved $5

Total money earned in babysitting = $84

We need to find Total money he saved.

Now 14 dollars earned = Money Saved $5

So 84 Dollars earned = Total Money saved

We will use Cross Multiplication method to find the Total Money saved.

Total Money Saved = $\frac{5\times84}{14} = \$30$

Hence Rob saved $30 to buy new Mp3 player.

Answer: This is a Binomial problem where, n=49, p=0.15 and x=5

Therefore,

P(x=5) = $nCx P^{x} (1-p)^{n-x}$

= $49C5 (0.15)^{5} (1-0.15^{49-5}$

= 0.1135

Can you help me with this question?

We can start by saying that 4/3w+ 3/3w = 133.
we can simplify to 7/3w = 133.
multiply both sides by 3 to get 7w = 399.
divide both sides by 7 to get 57.
