You build a model of Laurel Park using the scale 1.5 inches:10 feet. If the model 94.5
inches wide, what is the width of the school campus?
Answers
Answer:
The width of the school campus is:
[tex] \boxed{ \underline{ \rm{630 \: feet}}}[/tex]
Step-by-step explanation:
Scale = 1.5 inches : 10 feet
That means, 1.5 inches is equals to 10 feet in real.
Then for 1 inch:
⇛ 10 / 1.5 feet
⇛ 10/3 feet
We need to find for 94.5 inches,
⇛ 94.5 inches = 94.5 × 2/3 feet
⇛ 94.5 inches = 63 feet
Thus, the width of the school campus is 63 feet.

Tomas is a commercial real estate agent who earns a yearly salary of $82,500 and a 2.5% commission on his total sales. If Tomas sold properties that totaled $3.75 million in sales during one year, what are Tomas’s earnings for that year?
Answers
Answer:
$176,250
Step-by-step explanation:
Multiply $3.75 million by Tomas commission on his total sales. Since you can't multiply a percentage you have to turn the commission into a decimal by moving it two spaces to the left. (Note: If it doesn't have a decimal add one at the end of the number then move it two spaces to the left)
$3,750,000 x .025 or 0.025 = $93,750
Add $93,750 to Tomas yearly salary
$93,750 + $82,500 = $176,250
So
If Tomas sold properties that totaled $3.75 million in sales during one year, his earnings for that year would be $176,250
A store pays $1.50 for a bag of candy. If the store wants to mark-up the price 60%,
for how much will the store sell the bag of candy?
Answers
Answer:
Selling price = $2.4
Step-by-step explanation:
Given:
Purchase price = $1.50
Increase in price = 60%
Find:
Selling price
Computation:
Selling price = Purchase price + (Purchase price)(Increase in price)
Selling price = $1.5 + (1.5)(60%)
Selling price = $1.5 + 0.9
Selling price = $2.4

Answers
Answer:
multiply by 25 also.
Step-by-step explanation:
If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.
If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.

You are given 3 to 1 odds against tossing three tails with three coins, meaning you win $3 if you succeed and you lose $1 if you fail. Find the expected value (to you) of the game. Would you expect to win or lose money in 1 game? In 100 games? Explain. Find the expected value (to you) for the game.
Answers
Step-by-step explanation:
To find the E(X) expected value, you come up with the different probabilities for each outcomeyour set of outcomes after 3 tosses would be = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} where H is heads and T is tailsEach element has a probability of 1/8 so let x represent number of tails[tex]Probability(x)=P(x)\\P(0)=\frac{1}{8} \\P(1)=\frac{3}{8} \\P(2)=\frac{3}{8} \\P(3)=\frac{1}{8}[/tex] The E(x)=Summation (x times P(x))[tex]E(X)=(0)(0.125)+(1)(0.375)+(2)(0.375)+(3)(0.125)=1.5[/tex] Now which probability is 1.5 tails? None, so it is either 2 tails or 1 tailsSo you can expect to lose money in 1 gameBut as you play more games the probability of getting 3 tails becomes more and more likely, so you can expect to win in a 100 gamesThe expected value is the value of winning made on a game when played overtime. Hence, the expected value of the game is -$0.5 ; with the player losing -$0.5 in the long run.
A coin toss :
{H, T}Sample space for 3 tosses :
{HHH, HHT, HHT, HTT, HHT, HTT, HTT, TTT}Toss required to win = 3 tails :
Amount won on success = $3 Amount lost otherwise = $1 = - $1Creating a discrete probability table :
X _____ 3 _______ - 1P(X) ___ 1/8 _____ 7/8The expected probability can be defined as :
E(X) = ΣX×P(X)E(X) = 3 × (1/8) + (-1) × 7/8
E(X) = 3/8 - 7/8 = - 4/8 = -1/2
Therefore, the expected value of the game = - 0.5 ; meaning that, I'll lose 0.5 in the long run.

A) seven sixteenths
B) ten sixteenths
C) seven eighths
D) ten eighths
Answers
Answer:
c
Step-by-step explanation:
The improper fraction is ten eighths(10/8).
What is improper fraction?Improper fractions are ones that have been divided improperly for any number, object, or element, as indicated by the term. A fraction is a portion of a whole in mathematics. Denominator and numerator are the two components of fractions.
A fraction whose numerator exceeds the denominator is referred to as an improper fraction. Consider the case where x/y is an improper fraction and x exceeds y. The incorrect fraction is consequently always bigger than one.
Given two times five eighths.
we need to multiply 2 by 5/8
First, remember that 2 is equal to 2/1 since 2 divided by 1 equals 2. Therefore, frame the issue as follows to begin:
2/1 x 5/8
Combine the denominators (1 x 8) and the numerators (2 x 5 = 10) to create a single fraction, as seen below:
10/8
Hence two times five eighths is 10/8 in improper fraction.

Answer: The area of the triangle is 25 units^2.
Step-by-step explanation: The formula to find the area of the triangle is (base * height)/2. In this case, the base is 10 units long (on the x axis, it's the overall horizontal length of the triangle) and the height is 5 units long (the height can be calculated by finding the y axis length from the highest point of the triangle to the lowest). So (10*5)/2 = 50/2 which equals 25. And keep in mind, because this is the area, the unit will be units squared.
