Explanation:
The price drops by 35%, so it keeps the remaining 65% (since 100-35 = 65)
65% of $60 = 0.65*60 = 39 dollars
-------
A slightly longer method:
35% of 60 = 0.35*60 = 21
You save $21 and the final price is 60-21 = 39 dollars

The population of Sasquatch in a certain county can be modeled by the function P(t) = 140t t + 14 , where t = 0 represents the year 1803. What is the applied domain of P? Find P(0) and indicate the proper units. (Round your answer to the nearest whole number. ) Find P(250) and indicate the proper units. (Round your answer to the nearest whole number. )
The interpret of P(0) is 0 and P(250) = 132.58. The domain of P is [0, ∞]
The population of Sasquatch in Portage County can be modeled by the function P(t) = 140t/(t + 14) where t represents the number of years since 1803.
We have to interpret P(0).
To interpret P(0) we put t = 0 in the function then solve the function.
The function is:
P(t) = 140t/(t + 14)
Putting t = 0
P(0) = (140 × 0)/(0 + 14)
P(0) = 0/14
P(0) = 0
Now we interpret P(250) by putting t = 250.
P(250) = (140 × 250)/(250 + 14)
P(250) = 35,000/264
P(250) = 132.58
The domain of the time cannot be negative. So the domain of P is [0, ∞].

The probability that Sam's first upgrade will occur after the third flight = 0.729
Let m represents the number of flights Sam must take in order to receive his first upgrade.
To find the probability that Sam's first upgrade will occur after the third flight.
i.e., to find P(m ≥ 4)
Here, 0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight.

Mrs. Bready has a large bag filled with red and green cards. She tells the class that 15% of the cards are red and
85% are green. At the end of each class, she mixes the cards, reaches inside the bag, and draws out one card at
random. If a red card is drawn, the students will not be assigned homework. She shows the class the card, and
then places the card back in the bag. Carla would like to carry out a simulation to estimate the number of days it will take in order to get a "no homework" day. She assigns the digits to the outcomes.
00-14 = red
15-99 = green
Beginning at line 1 carry out one trial of this simulation. Use additional lines as needed. How many days does it take to find the first "no homework" day?
A)1
B)3
C)9
D)18
According to the concept of average it will take 3 days in order to get a "no homework" day.
The term called average in math is defined as the number you get when you add two or more figures together and then divide the total by the number of figures you added.
Here we know that Mrs. Bready has a large bag filled with red and green cards. She tells the class that 15% of the cards are red and 85% are green.
And here we need to determine the average number of days that it will take in order to get a "no homework" day based on these 5 trials,
Then the following calculation must be performed as,
=> 0.85 x 0.85 x 0.85 x 0.85 x 0.85 = X
=> x = 0.4437
Hence it will take 4.2 days in order to get a "no homework" day.
Here we have already know that the first trial is carried out then we have to subtract it from the total number then we get,
=> 4.2 - 1 = 3.2
When we round off the value then we get 3.

Find perimeter and area of the rectangle simplify completely.
The perimeter of the rectangle = (6 x + 8) meters. and the Area is
2x² +10x.
How to find perimeter of rectangle?step 1: The first side's length is (x+ 5) metres, while the second side's breadth is (2x+ 1) metres.
Now, the RECTANGLE'S PERIMETER = 2 (LENGTH + WIDTH).
Here, perimeter is equal to 2 ((x+ 5) m + (2x + 1) m) or 2 (x + 5 + 2x +1) = 2(3x + 4) = 6x + 8
Therefore, the rectangle's perimeter is equal to (6 x + 8) metres.
step 2:
Area of a rectangle equals length times breadth
Given:
Size = x+5
Thickness = 2x+1
Area of rectangle = length breadth = (x+5) (2x+1) = 2x (x+5) (2x+1) =2x2+5+4x+1 =2x2+10x, according to the query.

Mrs. Hitchcock gave a test to each of her two classes and calculated the averages. Her Theater class has a standard deviation of 18. 7, and her British Literature class has a standard deviation of 1. 2.
Which class most likely larger? Why?
A the British Literature class, because the standard deviation is lower
B the Theater class, because the standard deviation is higher
C the British Literature class, because the standard deviation is higher
D the Theater class, because the standard deviation is lower
(A) The British literature class is most likely larger, because the standard deviation is lower.
A high standard deviation suggests that the observed data is very variable around the mean. This suggests that the observed data is widely dispersed. Instead, a modest or low standard deviation would suggest that the majority of the observed data is closely packed around the mean.
The standard deviation measures the degree of dispersion of a set of data. Each data point is compared to the average of all the data points, and standard deviation gives a determined value that indicates whether the data points are clustered together or dispersed.
Hence, when standard deviation is lower the class is most likely to be larger in number.
