I am thinking of a number. It has two digits. When I reverse the digits and then add the new number to the original number I get 33. What is the number?
Answers
Let x and y be the digits.
The original number has two digits that means that one is the tens and the other the ones, in this case let x be the tens and y the ones, then we have the number:
[tex]10x+y[/tex]if we reverse it this means that the y become the tens and x becomes the ones then we have the number:
[tex]10y+x[/tex]And if we add them the result is 33, then we have the equation:
[tex]\begin{gathered} (10x+y)+(10y+x)=33 \\ 11x+11y=33 \\ x+y=3 \\ y=3-x \end{gathered}[/tex]This means that y has to be 3-x. Now, since we both numbers to have two digits x can't be zero nor 3. Then has to be 1 or 2.
If x=1 then y=2 and the original number is 12.
If x=2 then y=1 and the original number is 21.
Notice how in both cases we get the other one when reversed, therefore the numbers we are looking for are 12 and 21.
5. Match the equation with its graph.4x + 8y = 32
Answers
In order to find the corresponding graph, let's find two points that are on the line.
To do so, let's choose values of x and then calculate the corresponding values of y:
[tex]\begin{gathered} x=0\colon \\ 0+8y=32 \\ y=\frac{32}{8}=4 \\ \\ x=8\colon \\ 32+8y=32 \\ 8y=0\to y=0 \end{gathered}[/tex]So we have the points (0, 4) and (8, 0).
Looking at the options, the graph that has these points is the fourth graph.

The perimeter of a rectangle is less than 10 inches. The length is x and the width is x - 5. If the solution is x<5, ThEn the length is less than 5. Is this viable solution.
Solution
For this case the perimete rof a rectangle is given by:
P= 2x+2y
x= lenght y = width
And we also know that y= x-5
And replacing the condition given: P<10 we got:
2x +2y <10
2x +2(x-5)<10
4x -10 >10
And we can rewrite as:
4x >20
x>5

You pick a card at random put it back and then pick another card at random what is the probability of picking a number greater than 5 and then picking a 5 right and then picking a 5 write your answer as a percentage
Answers
You have four cards numbered 4, 5, 6, and 7.
Step 1
To calculate the probability of picking a card at random, and that this card has a number greater than 5, you have to divide the number of successes by the number of possible outcomes.
Successes: You want to pick a card with a number greater than 5, there are only two cards that meet this condition, the card numbered 6 and the card numbered 7, so for this scenario, there are 2 successes.
Total outcomes: The number of outcomes is equal to the total number of cards you can pick from, in this case, the total number of outcomes is 4.
Next, calculate the probability of picking a card with a number greater than 5:
[tex]\begin{gathered} P(X>5)=\frac{nºsuccesses}{Total\text{ }outcomes} \\ P(X>5)=\frac{2}{4} \\ P(X>5)=\frac{1}{2}=0.5 \end{gathered}[/tex]The probability of picking a card with a number greater than 5 is 0.5.
Step 2
Next, you put the card back and pick another one at random.
You have to calculate the probability that this time you will pick the card numbered 5.
To calculate this probability you have to divide the number of successes by the total number of outcomes.
Successes: there is only one card with the number 5, so the number of successes is 1.
Total outcomes: since the first card that was drawn was returned to the deck, the total number of outcomes is still 4.
Calculate the probability of drawing a 5:
[tex]\begin{gathered} P(X=5)=\frac{nºsuccesses}{Total\text{ }outcomes} \\ P(X=5)=\frac{1}{5}=0.2 \end{gathered}[/tex]The probability of drawing a 5 is 0.2.
Finally, the probability that you have to determine is to "draw a card with a number greater than 5 and then pick a 5"
The event described is the intersection of both events "drawing a card greater than 5" and "picking a 5". Since the first card was returned to the deck before drawing the second card, both events are independent, which means that the probability of their intersection is equal to the product of the individual probabilities of the events, so that:
[tex]P(X>5\cap X=5)=P(X>5)*P(X=5)=0.5*0.2=0.1[/tex]The probability is 0.1.
Multiply the result by 100 to express it as a percentage:
[tex]0.1*100=10\%[/tex]The probability of picking a number greater than 5 and then picking a 5 is 10%.
A ball is thrown in the air from a platform. The path of the ball can be modeled by the function h(t)=-16 t^{2}+32t+4 where h(t) is the height in feet and t is the time in seconds.How long does the ball take to reach its maximum height?
Answers
Answer:
1 second
Explanation:
The equation that models the path of the ball is given below:
[tex]h\mleft(t\mright)=-16t^2+32t+4[/tex]To determine how long it takes the ball takes to reach its maximum height, we find the equation of the line of symmetry.
[tex]\begin{gathered} t=-\frac{b}{2a},a=-16,b=32 \\ t=-\frac{32}{2(-16)} \\ =-\frac{32}{-32} \\ t=1 \end{gathered}[/tex]Thus, we see that it takes the ball 1 second to reach its maximum height.

Answers
The given points are
(352, 150)
(352, 175)
(456, 150)
(456, 175)
Each point represents one vertex of the rectangle.
The points that have the same x-coordinate are in the same vertical line, this means that the diference between the y-coordinates of the point determine the length of the width of the rectangle.
Since is a rectangle both vertical sides are equal.
Using the points
(352, 150)
(352, 175)
You can calculate the width as:
[tex]\begin{gathered} w=y_2-y_1 \\ w=175-150 \\ w=25\text{units} \end{gathered}[/tex]The points that have the same y-coordinate are in the same horizontal line, if you calculate the difference between the x-coordinates of said points, you can determine the length of the rectangle.
Using the points
(456, 150)

You can calculate the length as
[tex]\begin{gathered} l=x_2-x_1 \\ l=456-352 \\ l=104\text{units} \end{gathered}[/tex]So the rectangle has a length of 104 and a width of 25. Using these values you can calculate the area:

If the vector is pointing in the opposite direction of [-4,3], we can say it is pointing in the same direction of the vector [4,-3]. We just flipped the direction of the vector by changing the sign of the components.
We have now a vector that is pointing in the same direction of the vector we are looking for. Let's find the length of that vector to see how much it has to be scaled, or if it does not need to be scaled.
The length of the vector is calculated as the square root of the sum of the square of its components:
[tex]\text{Length}=\sqrt[]{x^2+y^2}[/tex]Then, the length of the vector is:
[tex]\begin{gathered} \text{Length}=\sqrt[]{4^2+(-3)^2}=\sqrt[]{16+9}=\sqrt[]{25} \\ \\ \text{Length}=5 \end{gathered}[/tex]Then the length of the vector [4,-3], which is pointing opposite to the vector [-4,3], happens to have a length of 5, then, that is the vector we were looking for.

4. Suppose that you receive a movie-rental bill for the month that is much higher thanit usually is. Currently you are paying $3.99 for each movie you rent. Switching to asubscription would allow you to watch unlimited movies for only $7.99 per month. However,during a normal month you don't have much time to sit and watch movies. You do not reallywant to waste your money on a monthly subscription. You decide to check your onlinebilling statements and make a probability distribution for the number of movies you mightwatch each month.The results are in the following table:Number of Movies, X 0 1 2 3 4 5Probability, P(X) 0.10 0.15 ? 0.35 0.14 0.13a) What is the probability you will watch 2 movies next month, i.e., P(X=2)?b) What is the probability that you will watch more than 2 movies next month, i.e., P(X<4) orP(X<=3)?c) How much would you expect to spend, on a per-month basis, should you continue to pay foreach movie separately? Explain your answer
Answers
For the given table representing the probability distribution, the probability of watching 2 movies is unknown.
The sum of all probabilities should be equal to 1. We can use that to calculate the unknown probability:
Adding all probabilities and equating to 1:
[tex]0.1+0.15+P(x=2)+0.35+0.14+0.13=1[/tex]Solving for P(x=2)
[tex]\begin{gathered} 0.87+P(x=2)=1 \\ P(x=2)=1-0.87 \\ P(x=2)=0.13 \end{gathered}[/tex]Then: A. The probability of watching 2 movies next month is 0.13.
The complete table of probability distribution will look like this:
xP(x)
00.1
10.15
20.13
30.35
40.14
50.13
To calculate the probability of watching more than two movies we need to add the probabilities of watching 3, 4 or 5 movies. Those should be added because those are the cases where more than 2 movies are watched.
[tex]\begin{gathered} P(x>2)=P(x=3)+P(x=4)+P(x=5) \\ P(x>2)=0.35+0.14+0.13 \\ P(x>2)=0.62 \end{gathered}[/tex]Then, B. The probability of watching more than 2 movies is 0.62.
The probability of watching 2 movies is equivalent to P(x>2) or P(x>=3).
On the other hand, to calculate P(X<4) or P(X<=3) we need to add the probabilities of watching 3 movies or less. That is, probabilities of watching 0, 1, 2 or 3:
[tex]\begin{gathered} P(x<4)\text{ or }P(x\le3)=P(x=0)+P(x=1)+P(x=2)+P(x=3) \\ P(x<4)\text{ or }P(x\le3)=0.1+0.15+0.13+0.35 \\ P(x<4)\text{ or }P(x\le3)=0.73 \end{gathered}[/tex]The probability of watching 3 movies or less next month is 0.73.
To estimate how much we would expect to spend per month if we pay for each movie sepparately we need to calculate the expected value of movies per month.
We can estimate that with the probability distribution given in the table.
The expected value is the sum of the products between each event and their probabilities:
[tex]\text{Expected Value}=\sum ^{}_{}x\cdot P(x)[/tex]Let's call EV the expected value:
[tex]\begin{gathered} EV=(0\cdot0.1)+(1\cdot0.15)+(2\cdot0.13)+(3\cdot0.35)+(4\cdot0.14)+(5\cdot0.13) \\ EV=2.67 \end{gathered}[/tex]Then, we should expect to watch about 2.67 movies per month, on average.
I each individual movie costs $3.99, then, the total expenses per month will be:
[tex]2.67\cdot3.99\approx10.65[/tex]Then, C. According to the given probability distribution, we should expect to watch about 2.67 movies per month, on average, and spend in total $10.65 per month. We would be spending more than we would if we selected the unlimited movies plan which costs only $7.99 per month, then, it would be wise to decide to change our subscription to that plan.

How many perfect squares less than 1000 have a ones digit of 2,3 or 4?
Answers
There are 200 perfect squares less than 1000 that have a ones digit of 2,3 or 4.
To check that perfect squares that have a ones digit of 2,3 or 4 :
First we will check the squares of 0-10 numbers.
[tex]0^{2} = 0[/tex] [tex]1^{2} = 1[/tex] [tex]2^{2} = 4[/tex]
[tex]3^{2} = 9[/tex] [tex]4^{2} = 16[/tex] [tex]5^{2} = 25[/tex]
[tex]6^{2}=36[/tex] [tex]7^{2}=49[/tex] [tex]8^{2}=64[/tex]
[tex]9^{2}=81[/tex] [tex]10^{2}=100[/tex]
As we can see, only 2,8 have the squares which have 2,3 or 4 at ones place.
So, only numbers like 12,18,24,28.........,998 have a ones digit of 2,3 or 4.
Hence, there are 200 perfect squares less than 1000 that have a ones digit of 2,3 or 4.

Answer: 6
Step-by-step explanation:
We can use brute force for this, because there are 31 numbers to try(32^2 is 1024, which is over 1000).
To begin with, there is no number that ends in 2 or 3 in the first 10 squares. If we move onto the ones digit of 4, we can see that:
2
8
12
18
22
28
Are the only numbers which end in a 4.
We add these up and we get the answer of 6.
