<u><em>Answer:</em></u>

She had more correct answers on the first quiz

<u><em>Explanation:</em></u>

<u>1- For the first quiz:</u>

We know that the quiz had a total of 15 questions and that Kelly had \frac{4}{5} of those correct

<u>This means that:</u>

Number of correct answers = \frac{4}{5}*15 = 12 answers

<u>2- For the second quiz:</u>

We know that the quiz had a total of 12 questions and that Kelly had \frac{5}{6} of those correct

<u>This means that:</u>

Number of correct answers = \frac{5}{6}*12=10 answers

<u>3- Comparing the number of correct answers:</u>

From the above calculations, we know that she had 12 correct answers on the first quiz and 10 on the second

<u>This means that</u> she had more correct answers on the first quiz

Hope this helps :)

1. Kane earns an annual salary of $42,500.
Katarina [22]

Answer:

$1753.13

Step-by-step explanation:

Kane's Annual Salary  = $42,500

Gross Pay = $42,500

Net Pay = Gross Pay - 1% of Gross Pay

=42500 - (0.01 X 42500)

=$42,075

Since he is paid twice a month with paychecks being  of equal amounts.

Number of Payments in a Year =12 X 2= 24

Therefore, Kane's Take Home pay after Medicare taxes

= \$42075 \div 24\\=\$1753.13$ (to the nearest cent)

In a lottery game, a player picks six numbers from 1 to 27. If the player matches all six numbers, they win 40,000 dollars. Othe
Alexus [3.1K]

Answer:

We conclude that  expected value of this game is -0.865$.

Step-by-step explanation:

We know that in a lottery game, a player picks six numbers from 1 to 27.

We know that

C_6^{27}=296010

As there is only one advantageous combination, we conclude that the number of non-winning combinations is 296009.

He can win 40,000 dollars.

We calculate:

E(X)=\frac{1}{296010}\cdot 40000\$- \frac{296009}{296010}\cdot 1\$\\\\E(X)=\frac{40000-296009}{296010}\, \$\\\\E(X)=-0.865\, \$

We conclude that  expected value of this game is -0.865$.
