Payton created a presentation for his parents showing how his grades have improved over the past six months. what is an alternative data display that would better convey the information?
Answers
I believe that aside from the bar graph, the line graph would actually best suits to convey this information. Because just like the bar graph, we can actually see the peaks of the grades. And through the peaks, we can easily compare the grades one by one.

Yuto left his house at 10 a. m. to go for a bike ride. By the time Yuto’s sister Riko left their house, Yuto was already 5.25 miles along the path they both took. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, over what time period in minutes, t, starting from when Riko left the house, will Riko be behind her brother? Riko will be behind Yuto when 0 ≤ t < minutes.

A $100 bill, Two $20 bills,three $10 bills, and four $5 bills are placed in the bag. If a bill is chosen at random and you have to pay $15 to play the game. what is the expected value for the game?
Answers
Final answer:
The expected value for the game is $4, which means on average a player would expect to gain $4 before the entry fee. However, after subtracting the cost to play ($15), the net expected value is -$11, indicating a loss on average for each play.
Explanation:
To determine the expected value of the game mentioned, we first identify the possible outcomes and their corresponding probabilities. Next, we multiply each outcome value by its probability, and sum up these products. Finally, we deduct the cost of the game ($15) from the sum to find the expected net gain or loss.
Probability of picking a $5 bill = 4/10
The expected value (EV) calculation would be:
EV = (1/10 * $100) + (2/10 * $20) + (3/10 * $10) + (4/10 * $5) - $15
EV = ($10) + ($4) + ($3) + ($2) - $15
EV = $19 - $15
EV = $4
Therefore, the expected value for the game is $4. This means on average you would expect to gain $4 per game before considering the entry fee. Since you pay $15 to play, you need to subtract this from the $4 gain to obtain the net expected value, which would be -$11, indicating a loss in the long run.

The two sides, AB and BC are equal
By Pythagoras, we find the length of AC = [tex] \sqrt{1^+1^} [/tex] = [tex] \sqrt{2} [/tex]
Using the sin ratio ⇒ sin θ = opposite/hypotenuse, we have
[tex]sin(45)= \frac{1}{ \sqrt{2} }= \frac{ \sqrt{2} }{2} [/tex]
Using the cos ratio ⇒ cos θ = adjective/hypotenuse, we have
[tex]cos(45)= \frac{1}{ \sqrt{2} }= \frac{ \sqrt{2} }{2} [/tex]
Using the tan ratio ⇒ tan θ = opposite/adjective, we have
[tex]tan(45)= \frac{1}{1}=1 [/tex]
The values of sine, cosine, and tangent for angle θ, where (1, -1) is on its terminal side, are sin(θ) = -1, cos(θ) = 1, and tan(θ) = -1, knowing that the point lies in the fourth quadrant.
To find the values of the sine, cosine, and tangent of an angle θ where the point (1, -1) is on its terminal side, we first recognize that this point lies in the fourth quadrant of the coordinate system. In this quadrant, cosine is positive, and sine and tangent are negative.
The point (1, -1) gives us the x and y coordinates on the Cartesian plane, which correspond to the lengths of the adjacent side and the opposite side of the right-angle triangle formed by the radius (hypotenuse) from the origin to the point, and the axes. Assuming we're dealing with a unit circle (which has a radius of 1), we can directly use the coordinates (1, -1) to find the cosine and sine:
cos(θ) = x = 1sin(θ) = y = -1tangent (θ) = y/x = -1/1 = -1Hence, for angle θ, cos(θ) is 1, sin(θ) is -1, and tan(θ) is -1.

11x^3 - 2x^2 + 3x + 11 <==
** its just a matter of combining like terms
Answer:
11x^3 - 2x^2 + 3x + 11
Step-by-step explanation:
we need to find the sum of 4x^3 + 2x^2 - 4x + 3 and 7x^3 -4x^2 + 7x + 8
To find the sum we add both the polynomials
4x^3 + 2x^2 - 4x + 3 + 7x^3 -4x^2 + 7x + 8
To add the polynomials we combine like terms
4x^3 + 7x^3 = 11x^3
2x^2 - 4x^2 = -2x^2
-4x+7x= 3x
3+8 = 11
So final expression is 11x^3 -2x^2 +3x+11
What is the solution of the system of equations?
Answers
We consider 2 pairs or equations, for example (1, 2) and (2, 3), and eliminate one of the variables in each pair, creating a system of 2 linear equations with 2 unknowns.
Note that the third equation contains -2y which can be used to eliminate easily -6y in the second equation, and -4y in the fourth.
i) consider equations 1 and 3:
-3x-4y-3z=-7
5x-2y+5z=9
multiply the second equation by -2:
-3x-4y-3z=-7
-10x+4y-10z=-18
adding the 2 equations we have -13x-13z=-25
ii) consider equations 2 and 3. Multiply the third equation by -3:
2x-6y+2z=3
-15x+6y-15z=-27
adding the 2 equations we have -13x-13z=-24
So we got -13x-13z is -25, but also -24. this means the system is inconsistent, so it has no solution.
Answer: the system has no solutions

perpendicular lines, slope is opposite and reciprocals
slope of line PQ = 1 and slope of line RS = -1

It takes Lee's cat about 20 days to finish a five pound bag of cat food. Which is the best estimate of the number of pounds of cat food Lee's cat eats In one year
Answers
Based on the daily consumption calculated from the given data, Lee's cat eats approximately 91.25 pounds of cat food in a year.
Explanation:The question is asking for the estimated number of pounds of food that Lee's cat eats in one year. Lee's cat consumes a five-pound bag of food in 20 days. So, let's first determine how much he eats in 1 day. If 5 pounds is consumed in 20 days, then in 1 day, the cat eats 5/20, or 0.25 pounds.
Since there are approximately 365 days in a year, we multiply this daily consumption by 365. So, 0.25 pounds/day * 365 days/year = 91.25 pounds/year.
So, the best estimate for the amount of cat food that Lee's cat eats in one year would be approximately 91.25 pounds.
