Answer:
15 = -3(2c + d), right?
So, 15 = -6c - 3d
If we're solving for c, then
-6c = 15 + 3d
c = -(15 + 3d) / 6

Construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. What percentage of players had a top speed between 14 and 17.9 km/h? What percentage of players had a top speed less than 13.9 km/h?
Answers

a)
0.3212
b)
The percentage of player that had a top speed less than 13.9 km/h = 0.007259 x 100 = 0.7259%

equal to $78, so my
Answers
The final stock price is $52.23.
The answer is reasonable because the price on day 3 is equal to $78.
Let's break down the given information step by step:
Luis bought the stock at $63.10.
The next day, the price increased by $17.25.
To find the new price after the increase, we can add the increase to the original price:
New Price = $63.10 + $17.25 = $80.35.
The new price then changed by -32%.
To calculate the decrease, we can multiply the new price by the percentage change in decimal form:
Decrease = 0.32 * $80.35 = $25.712.
To find the final stock price, we subtract the decrease from the new price:
Final Price = $80.35 - $25.712 = $54.638.
However, since we need to round the final price to the nearest cent, the final stock price becomes $54.64.
Therefore, the final stock price, rounded to the nearest cent, is $54.64.
Now, let's check if our answer is reasonable. It is stated that the price on day 3 is equal to $78. Since the initial price was $63.10 and it increased by $17.25 on day 2, the resulting price of $80.35 is higher than the expected price of $78 on day 3. Therefore, our answer of $54.64 is not reasonable.
In conclusion, the correct final stock price, considering the given information, cannot be determined based on the provided data.

Marcy has 12 bracelets and 15 necklaces. Shelly has 25 necklaces. If the ratio of Marcy’s bracelets to her necklaces is the same as the ratio of Shelly’s bracelets to her necklaces, how many bracelets does Shelly have?
Answers
Answer:
20 bracelets
Step-by-step explanation:
So Marcy has 12 bracelets and 15 necklaces. It is stated in the problem that this ratio (12:15) is the same as the ratio of Shelly's bracelets to necklaces (x:25). To solve this, we set up a proportion like so:
12/15=x/25 and we can use cross multiplication to solve for x. x=20, so the answer is 20 bracelets.

Two players play the following game. Player A chooses one of three spinners. Spinner 1 has 3 regions numbered 9,5 and 1, Spinner 2 has three regions numbered 3,8 and 4, and Spinner 3 has three regions numbered 7,6 and 2. Player B then chooses one of the two remaining spinners. Both players spin their spinner and the one that lands on the higher number is declared the winner. Assuming that each spinner is equally likely to land in any of its 3 regions, would you rather be player A or player B?
Answers
Answer:
Hence, player A will win with probability = 5/9. Explanation has given below.
Step-by-step explanation:
Two player such as A and B chose the three spinners and contain numbered 9 , 5 and 1.
Spinner one has 3 regions = (9, 5, 1)
Spinner 2 has three regions= (3, 8, 4)
Spinner 3 has three regions = (7, 6, 2)
Let
Player A chooses one of three spinners = (9, 5, 1)
Player B chose spinner = (3, 8, 4)
Possible outcomes are = [ (9,3), (9,8), (9,4), (5,3), (5,8), (5,4), (1,3), (1,8), (1,4)]
Total possible outcomes are = 9
One with the higher number wins the game.
Player A wins = (9,3), (9,8), (9,4), (5,3), (5, 4)
Player B wins = (5, 8), (1,3), (1,8), (1,4)
Hence, player A will win with probability = 5/9.

Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -2, m= -2.
Substitute m= -2 into the equation:
y= -2x +c
Given that the y-intercept is 2, c= 2.

calculate the average of 13,14,12,9,8 and 10
Answers
Answer:
4.992 or just 5
Step-by-step explanation:
The average of the given numbers 13, 14, 12, 9, 8, and 10 is equal to 11.
To calculate the average of a set of numbers,
Add up all the numbers and then divide the sum by the total count of numbers.
Let's calculate the average of the given set of numbers: 13, 14, 12, 9, 8, and 10.
Add up all the numbers.
Sum = 13 + 14 + 12 + 9 + 8 + 10
Sum = 66
Find the total count of numbers, which is 6 in this case since there are 6 numbers in the set.
Calculate the average by dividing the sum by the total count.
Average = Sum / Total count
Average = 66 / 6
Average = 11
Therefore, the average of the numbers 13, 14, 12, 9, 8, and 10 is 11.

The height of the cylinder is 4 feet.
We'll be analyzing the surface area of a round cylinder - in other words the amount of material needed to "make a can".
A cylinder (round can) has a circular base and a circular top with vertical sides in between. Let r be the radius of the top of the can and let h be the height. Since the top and bottom both are circles with radius r, the areas of the top and bottom both are πr2. You can think of the side as a rolled up rectangular piece that is h long by (the circumference of the circle) 2πr wide, so the side has a total area of h(2πr)
Thus the surface area of the cylinder, A, is A=2πr2+2πrh.
Part a: Assume that the height of your cylinder is 4 inches. Consider A as a function of r, so we can write that as A(r). What is the domain and range of A(r)?
Part b: Continue to assume that the height of your cylinder is 4 inches. Write the radius r as a function of A. This is the inverse function to A(r), i.e. r as a function of A or r(A). What is r(A) and what is the domain and range of r(A)? What is r(A)? (Do not include the units "inches" in your answer.)
Hints: Mobius accepts the following ways to type in mathematics:
To enter a square root such as x+3−−−−−√, you can type in sqrt(x+3)
To enter the number π, you can type in pi
To enter a division such as x+3y+1, you can type in (x+3)/(y+1)
Remember to use parentheses for order of operations!
Part c: If the surface area is 175 square inches, then what is the rardius r? Round your answer to 2 decimal places.
Hint: To compute a numeric square root such as 17.3−−−−√, you could
Use a spreadsheet such as Microsoft Excel or OpenOffice Calc and type in =sqrt(17.3)
Use a browser to connect to the Internet and type in sqrt(17.3) into a search field
use a calculator

Answers
Answer:

onto the first problem:
72% * (of) 32
0.72 * 32
