Answer:$9.16

Step-by-step explanation:

What I did was 20% of $45.80! If you have a tip or a percent problem you can think of it as that percent of the certain number. In math "of" means mupltiply.

Punch in your calculator .2 which is 20% times 45.8 and you get your answer $9.16.

Tom and Martin both worked 9 hours this week and sold $360 worth of meals. Their hourly wages are $2.15 and $2.50, respectively.

serious [3.7K]

Tom and Martin worked 9 hours this week.

These are their hourly wages:

Tom: $2.15

Martin: $2.50

This means that:

Tom earned 9 x $2.15 in wages, which is equal to $19.35.

Martin earned 9 x $2.50 in wages, which is equal to $22.50.

--------------------

Now, we've been told that Tom and Martin sold $360 worth
of meals but we were not told how much they received in tips.

For all intents and purposes, let's say that they received $n
in tips. 15% of $n in tips would be less than 20% of $n
in tips. Now, Martin is already going to be receiving a higher
wage, and the fact that he is going to be receiving 20% of
$n in tips compounds the logical conclusion that at the end
of the week, he'd be leaving work with more money than Tom.

Answer:

Martin made more money than Tom.

Using translation concepts, the coordinates that will best represent point E′ are given by:

D. (11, 1).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the rule to find the image of a point (x,y) is given by:

(x, y) → (x + 8, y + 5).

Then, the rule to find the image E' of point E(3,-4) is given by:

(3,4 -> (3 + 8, -4 + 5) = (11,1).

Hence option D is correct.

Find the explicit formula for arithmetic sequences. 38, 238, 438, 638, ..

Eddi Din [679]

Answer:

200n - 162.

Step-by-step explanation:

first trem a1 = 38

common difference d = 200

nth term = a1 + (n-1(d

= 38 + 200(n-1)

= 200n - 162

Best of three In a best out of three series played between teams A and B, the team that gets two wins first wins the entire seri

konstantin123 [22]

Answer:

a) P (x = 2 games ) = 0.49 + 0.09 = 0.58

P ( x = 3 games ) = 0.063 + 0.147 + 0.147 + 0.063 = 0.42

b) = 2.42 ≈ 2 games

c) P (x = 2 games ) = 0.49 + 0.09 = 0.58

Step-by-step explanation:

Team A chance of winning a game in the series. P( team A ) = 70% = 0.7

P ( team B ) = 0.3

probability of series ending after two games = 58% = 0.58

A) Determine the probability distribution of X number of games played in the series

First we have to consider the possible combinations that will decide the series and they are

( A,A ) , ( B,B) , ( A,B,B) , ( A,B,A ) , ( B,A,A ), ( B,A,B) = 6 Combinations

( A,A ) = 0.7 * 0.7 = 0.49

( B,B ) = 0.3 * 0.3 = 0.09

( A,B,B ) = 0.7 * 0.3 *0.3 = 0.063

( A,B,A ) = 0.147

( B,A,A ) = 0.147

( B,A,B ) = 0.063

The distribution of the games in the series can be either game or three games before the end of the series

P (x = 2 games ) = 0.49 + 0.09 = 0.58

P ( x = 3 games ) = 0.063 + 0.147 + 0.147 + 0.063 = 0.42

B) the expected number of games to be played

∑ x(Px) = ( 2 * 0.58 ) + 3 ( 0.42 ) = 2.42 ≈ 2 games

C) Verify that the probability that series ends after two games = 58%

sample space of all possible sequences of wins and losses

( A,A ) , ( B,B) , ( A,B,B) , ( A,B,A ) , ( B,A,A ), ( B,A,B) = 6 Combinations

( A,A ) = 0.7 * 0.7 = 0.49

( B,B ) = 0.3 * 0.3 = 0.09

( A,B,B ) = 0.7 * 0.3 *0.3 = 0.063

( A,B,A ) = 0.147

( B,A,A ) = 0.147

( B,A,B ) = 0.063

hence :

P (x = 2 games ) = 0.49 + 0.09 = 0.58
