Tomás found the following prices when he was shopping for sports jerseys: $28, $36, $40, $30, and $28. What is the median price?
Answer:
$30
Step-by-step explanation:
To find the median, arrange numbers from smallest to largest
The # of data points in this scenario are 5, which is odd. If the # of data points is odd, the median is the data point in the center.
$28, $28, $30, $36, $40
if you wanted to find the median with an even # of data points, it's the average of the two middle data points.
The median price of the sport jerseys is : $30
Given the prices :
$28, $36, $40, $30, $28
To find the median price, we need to arrange the values in order :
Ordered prices = $28, $28, $30, $36, $40
The median formula = 1/2(n+1)th term
n = number of terms = 5
Hence,
Median price = 1/2(5 +1)th term
Median price = 1/2(6) = 3rd term
The 3rd term = $30.
Hence, the median price is $30

If the temperature was −3 degrees in the morning and 8 degrees in the afternoon, the change in temperature during that time is ____ degrees.
If the temperature has been changing at a rate of −1.5 degrees each hour, and it is currently 5 degrees, the temperature 4 hours ago was ___ degrees.
If the temperature continues to change at this rate of −1.5 per hour, and it is currently 5 degrees, the temperature in 4 hours will be ____ degrees.
Answer:
30, +11, 11, -1
Step-by-step explanation:
-10 + 30 = 10, 40 - 30= 10
-3 + 11 = 8
5 + (1.5 x 4) = 11
5 - (1.5 x 4) = -1
Suppose y varies directly as x, and y = 9 when x = 36. Find y when x= 100.
Answer:
25
Step-by-step explanation:
let x = 36
y = 9
x2 = 100
y2 = y2
y : x :: y2 : x2
We know,
Product of means = Product of extremes
That is,
y(x2) = x(y2)
Substituting the values,
9(100) = 36(y2)
=> 36(y2) = 900
=> y2 = 900/36
=> y2 = 25
so when x = 100, y =25

6a -5 = 4a
Subtract 6a from both sides
-5 = -2a
a = 2.5
6a - 5 = -4a
Subtract 6a from both sides

Answer:
a=1/2 and a=5/2
Step-by-step explanation:
6a-5=4a:
Subtract 4a from both sides, ending up with 2a-5=0
Add 5 to both sides, ending up with 2a=5
Divide both sides by 2, ending up with a=5/2
6a-5=-4a
Add 4a to both sides ending up with 10a-5=0
Add 5 to both sides ending up with 10a=5
Divide both sides by 10 ending up with a=1/2

Members of a lacrosse team raised $1814.75 to go to a tournament. They
rented a bus for $1168.50 and budgeted $58.75 per player for meals. Which
equation could be used to determine 2, the number of players the team can
bring to the tournament?
x = (1814.75 - 1168.50)/(58.75)
==============================================
Explanation:
x = number of players
58.75x = cost of all the meals for those x players
58.75x + 1168.50 = adding on the cost of the bus
58.75x + 1168.50 = 1814.75
----------
Let's solve for x.
58.75x + 1168.50 = 1814.75
58.75x = 1814.75 - 1168.50
x = (1814.75 - 1168.50)/(58.75)
x = 11
This means 11 players can go on the trip.
1 player = $58.75 in meals
11 players = 11*58.75 = $646.25 total in meal costs
646.25 + 1168.50 = 1814.75
So this confirms the answer.
The correct equation to determine the number of players (x) the team can bring to the tournament is x = (1814.75 - 1168.5) / 58.75.So, the correct answer is B. x = (1814.75-1168.5)/58.75
The amount raised by the lacrosse team is $1814.75. They spent $1168.50 on the bus rental and budgeted $58.75 per player for meals. Let's break down the expenses:
Total expenses = Bus rental cost + (Number of players * Meal cost per player)
Total expenses = $1168.50 + (x * $58.75)
The equation that represents the total expenses in terms of the number of players (x) is: Total expenses = $1168.50 + $58.75x
Since the team raised $1814.75, we can set up the equation:
Total expenses = Amount raised
$1168.50 + $58.75x = $1814.75
Now, let's solve for x:
$58.75x = $1814.75 - $1168.50
$58.75x = $646.25
Dividing both sides by $58.75:
x = $646.25 / $58.75
x = 11
So, the correct equation to determine the number of players (x) the team can bring to the tournament is: B. x = (1814.75 - 1168.5) / 58.75

a) y = [tex]\frac{1}{2} x[/tex]
b) y = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
I. If y = 9 and x = 18
so x is double value of y or y * 2
y will be half of x value
that makes y = [tex]\frac{1}{2}[/tex] x
II. If x = 5, replace x with 5
y = [tex]\frac{1}{2}[/tex] (5)
y = [tex]\frac{5}{2}[/tex]

(a).
[tex]{ \boxed{ \sf{y = \frac{1}{2}x }}}[/tex]
b).

[tex]{ \sf{y \: \alpha \: x}} \\ { \sf{y = kx}} [/tex]
when y is 9, x is 18
[tex]{ \sf{9 = (k \times 18)}} \\ { \sf{k = \frac{1}{2} }}[/tex]

Eduardo has in his pocket $1 in pennies, $1 in nickels, and $1 in dimes. If he randomly pulls out just one coin, what is the probability that he will pull out a dime?
The probability of picking a dime from the coins in his pocket is 1/13
1 penny = 1 cent
Hence, 100 pennies = $1
1 nickel = 5 cent
20 nickels = $1
1 dime = 10 cent
10 dime = $1
This means that :
Eduardo has :
100 pennies 100 pennies 20 nickels 100 pennies 20 nickels 10 dimesTotal coins = (100 + 20 + 10) = 130 coins
Recall :
Probability = required outcome / Total possible outcomes
P(dime) = number of dimes / total coins
P(dime) = 10 / 130 = 1/13
Hence, the probability of picking a dime = 1/13
