The answer is D. <span>$780.25 
</span>
In this particular case, you just need to find the difference between what Casey earn hourly with his total earning..

The hourly wage that Casey earned in 26 hours:
$ 4.55 x 26 = 118.3

The total amount that casey earned in 26 hours:
$898.55

So, the amount that Casey earned through tips:
$898.55 - $118.3 = $780.25

In fall 2014, 36% of applicants with a Math SAT of 700 or more were admitted by a certain university, while 18% with a Math SAT
Snezhnost [94]

Answer:

The percentage of admitted applicants who had a Math SAT of 700 or more is 48.48%.

Step-by-step explanation:

The Bayes' theorem is used to determine the conditional probability of an event <em>E</em>_{i}, belonging to the sample space S = (E₁, E₂, E₃,...Eₙ) given that another event <em>A</em> has already occurred by the formula:

P(E_{i}|A)=\frac{P(A|E_{i})P(E_{i})}{\sum\limits^{n}_{i=1}{P(A|E_{i})P(E_{i})}}

Denote the events as follows:

<em>X</em> = an student with a Math SAT of 700 or more applied for the college

<em>Y</em> = an applicant with a Math SAT of 700 or more was admitted

<em>Z</em> = an applicant with a Math SAT of less than 700 was admitted

The information provided is:

P(Y)=0.36\\P(Z)=0.18\\P(X|Y)=0.32

Compute the value of P(X|Z) as follows:

P(X|Z)=1-P(X|Y)\\=1-0.32\\=0.68

Compute the value of P (Y|X) as follows:

P(Y|X)=\frac{P(X|Y)P(Y)}{P(X|Y)P(Y)+P(X|Z)P(Z)}

             =\frac{(0.32\times 0.36)}{(0.32\times 0.36)+(0.68\times 0.18)}

             =0.4848

Thus, the percentage of admitted applicants who had a Math SAT of 700 or more is 48.48%.

The width of a rectangle measures (2p - 9q) centimeters, and its length measures
Alexxx [7]

Given Data : Length = (7p - 10q) and Breadth = (2p - 9q)

Calculation :

⟹ Perimeter = 2(Length + Breadth)

⟹ Perimeter = 2(7p - 10q + 2p - 9q)

⟹ Perimeter = 2(9p - 19q)

⟹ Perimeter = <em>18p - 38q centimetres</em>

  • <u>Answer : 18p - 38q centimetres</u>
