Answer:

77.78%

Step-by-step explanation:

Let us start this problem by finding the fraction of games the Cubs won in that season. In the numerator, we should have the number of games they won. In the denominator, we will have the total number of games they played.

Let us find the number of games the Cubs won. We know they played a total of 18 games and lost 4 games. Therefore, the remainder must be the games they won -- we subtract the two values:

18-4=14 games won

As mentioned before, we also know the total number of games they played, given to us -- 18 games. We can now form our fraction and simplify it.

\frac{14}{18} =\\\frac{7}{9}games won

To find the percent, let us find the decimal value first. After calculation, \frac{7}{9} = 0.7778

To convert this value into a percentage, we simply <em>shift the decimal point to digits to the right</em>. We now have

77.78%

<u>Therefore, the Cubs won 77.78% of their games.</u>

svetlana [45]

Answer:

C. The mean is 111.9F and the median is 114.5F.

Step-by-step explanation:

The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.

Organizing the values we have:

[93, 105, 107, 113, 116, 118, 121, 122]

We find that the median is going to be between 113 and 116. Therefore:

(113 + 116) / 2 = 114,5

Therefore, the correct answer is option C.

Solve for y.<br> r/3-2/y=s/5
nordsb [41]

Answer:

y = 2 / (r/3 - s/5)

Step-by-step explanation:

r/3 - 2/y = s/5

add 2/y to both sides

r/3 = s/5 + 2/y

Subtract s/5 from both sides

r/3 - s/5 = 2/y

multiply both sides by y

y(r/3 - s/5) = 2

Divide both sides by r/3 - s/5

y = 2 / (r/3 - s/5)

Sean's house is currently worth $188,900. According to a realtor, house prices in Sean's neighborhood will increase by 4.8% ever
mrs_skeptik [129]

Answer  

Given

Sean's house is currently worth $188,900.

According to a realtor, house prices in Sean's neighborhood will increase by 4.8% every year.

To prove

Formula

Compound\quaterly\ interest = Principle (1 + \frac{r}{4})^{4t}

Where r is the rate in the decimal form.

As given

Take\ Principle\ = P_{0}

Rate = \frac{4.8}{100}

              = 0.048

Put in the formula

Compound\quaterly\ interest = P_{0}(1 + \frac{0.048}{4})^{4t}

Compound\quaterly\ interest = P_{0} (1 + \frac{0.048}{4})^{4t}

Compound\quaterly\ interest = P_{0} (1 + 0.012)^{4t}       Compound\quaterly\ interest = P_{0} (1.012)^{4t}  

Now also calculated monthly.

Formula

Compound\ monthly = Principle (1 + \frac{r}{12})^{12t}

As given

Take\ Principle\ = P_{0}

Rate = \frac{4.8}{100}

              = 0.048

Put in the formula

Compound\ monthly = P_{0} (1 + \frac{0.048}{12})^{12t}

Compound\ monthly = P_{0} (1 + 0.004)^{12t}

Compound\ monthly = P_{0} (1.004)^{12t}

As the approximation quarterly growth rate of the value of sean's house is near the Compounded quarterly interest .

Thus Option (A) is correct.

i.e

The expression (1.0118)^{4t} reveals the approximate quarterly growth rate of the value of Sean's house.

19) At a local river, there were 48 alligators lying on the riverbank. If of the alligators wereasleep, how many were not asleep
sergey [27]
19) 48 alligators; 7/8 of the alligators were asleep. How many were not asleep?

8/8 - 7/8 = 1/8
48 * 1/8 = 48/8 = 6 alligators were not asleep.

20) 2/3 of the student population participated. 1,500 is the student population of the school. HOw many attended the bike rally?

1500 * 2/3 = 1500*2 / 3= 3000 / 3 = 1000 students attended.

21) 18 times at bat:
Kayla 5/6 of the time = 18 * 5/6 = 18*5 / 6 = 90/6 = 15 hits
Tia 8/9 of the time = 18 * 8/9 = 18*8 / 9 = 144/9 = 16 hits

Tia got more hits.
