The average weight of eleven people at a party is 138 pounds. When two people arrive late to the party, the average increase to 148. What is the average weight of the two people who arrived late?
11 people x 138 = 1,518 total pounds.
13 people x 148 = 1,924 total pounds.
Difference = 1924 - 1518 = 406 pounds.
Average weight = 406/2 = 203 pounds
The average of the weight of the two people who arrived late for this considered case is found being 203 pounds.
How to find the mean of a data set?Mean(also called average) is the ratio of the sum of the values of the data set to the total number of values available in the data set.
Thus, we get;
[tex]\rm Mean = \dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}}[/tex]
Given that:
Average of weight of 11 people at party = 128New average of total 13 people at party (2 people came late) = 148Assume that:
Sum of weight of 11 people who came early = xSum of weight of 2 people who came late = yThen, we get:
Average of weight of 11 people at party =
[tex]\dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}} = \dfrac{x}{11} =138[/tex]
Thus, we get:
[tex]x = 11 \times 138 = 1,518 \: \rm pounds[/tex]
The weight of all 13 people is sum of weight of 11 people + sum of weight of those 2 people who came late = x + y, therefore, we get:
Average of weight of 13 people at party =
[tex]\dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}} = \dfrac{x+y}{13} = 148[/tex]
Thus, we get:
[tex]\dfrac{1518 + y}{13} = 148\\1518 + y = 13 \times 148\\\\y = 1924 - 1518 = 406 \: \rm pounds[/tex]
That means, sum of weights of 2 people who came late = 406 pounds.
Thus, average weight of the two people who arrived late = [tex]\dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}} = \dfrac{y}{2} = \dfrac{406}{2} = 203 \: \rm pounds[/tex]
Thus, the average of the weight of the two people who arrived late for this considered case is found being 203 pounds.

PLS HELP Two wizards make boxes with secret compartments to sell at the magic convention. Fred plans to make 160 boxes by the start of the convention Georgiana plans to make 25% fewer in the same amount of time. Fred makes 10 more boxes each day than Georgiana, and finishes his job 2 days before the convention. How many boxes does Georgiana make each day if she needs two extra days after the convention starts to complete her job?
The number of boxes that Georgiana makes each day if she needs two extra days is 6.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Two wizards make boxes with secret compartments to sell at the magic convention. Fred plans to make 160 boxes by the start of the convention Georgiana plans to make 25% fewer in the same amount of time.
The number of days Fred worked will be

He worked two days less Georgiana.

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?
Answer: 10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people

Amanda uses the recipe shown to make trail mix for a camping trip. How many cups of M&M's will she need to make 180 cups of trail mix?
Answer:
40 cups
Step-by-step explanation:
7 part nuts and 2 parts M&M makes up 1 trail mix
7 and 2 part = 9 parts in total
There are 180 cups in total, so each part would be:
180/9 = 20 cups = 1 part
Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:
M&Ms required = 2 * 20 = 40 cups
Help me, please, please!
x° = 118°
y° = 180° - (22° + 180° - x°)
y° = 180° - (22° + 180° - 118°)
y° = 180° - 22° - 180° + 118°
y° = 118° - 22°
y° = 98°
