The measure of center that best represents the data is mean and its values for José and Manuel are 20.1 and 21.8, respectively. Comparing the mean values, José generally scores less goals in a game than Manuel.
What is the measure of center for the number of goals scored?To find the measure of center that best represents the data, we will use the mean.
The measure is calculated by adding up all the values and dividing by the total number of values.
The mean number of goals for José is:
= (7+12+17+4+18+25+38+32+37+11)/10
= 20.1
The mean number of goals for Manuel is:
= (17+23+21+31+30+5+26+37+19+9)/10
= 21.8.

Jan accidentally ran 7 minutes longer than she was supposed to. Write an expression for the total amount of time Jan ran if she was supposed to run m minutes.
Answer:
m+7
Step-by-step explanation:
If she ran 7 minutes longer and m represents the amount of time she ran, then it would just be addition.
Let's say m=60 minutes. She would've ran for 67 minutes, which is also m+7.
4. a picture can be added to a text in nine different locations on a page. if four different pictures are to be placed in the text, how many different designs are there?
As per the combination method, there are 3,024 different designs that can be created with four different pictures placed in nine different locations on a page.
There are seven options for the third picture and six options for the fourth picture.
To determine the total number of designs, we can use the multiplication principle, which states that the number of ways two or more independent events can occur together is equal to the product of the number of ways each event can occur individually.
Therefore, the total number of designs that can be created by placing four different pictures in nine different locations on a page can be found by multiplying the number of options for each picture:
9 x 8 x 7 x 6 = 3,024

refer to table 13-12. firm 4's efficient scale occurs at what quantity?
The firm 4's efficient scale occurs at 4
In this question, we have been given a table of long-run total cost and the quantity.
We need to find the quantity at which the firm 4's efficient scale occurs.
We know that the efficient scale occurs at the quantity of output where average total cost is minimum.
For the firm 4 the average total cost would be,
(210 + 340 + 490 + 660 + 850 + 1060 + 1290) / 7
= 4900 / 7
= 700
This value is clsoe to 660.

Nicholas started a canned-food drive at school. The equation representing this is y = 235x + 15, where x is the number of days, and y is the number of cans collected. Explain how to determine how many days it would take to collect 2600 cans.
Answer:
11 days
Step-by-step explanation:
because Nicholas was given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

Suppose y varies inversely with x, and y = 49 when x = 17
. What is the value of x when y = 7 ?
Answer:
119 is the value of x when y = 7
Step-by-step explanation:
Since y varies inversely with x, we can use the following equation to model this:
y = k/x, where
k is the constant of proportionality.Step 1: Find k by plugging in values:
Before we can find the value of x when y = k, we'll first need to find k, the constant of proportionality. We can find k by plugging in 49 for y and 17 for x:
Plugging in the values in the inverse variation equation gives us:
49 = k/17
Solve for k by multiplying both sides by 17:
(49 = k / 17) * 17
833 = k
Thus, the constant of proportionality (k) is 833.
Step 2: Find x when y = k by plugging in 7 for y and 833 for k in the inverse variation equation:
Plugging in the values in the inverse variation gives us:
7 = 833/x
Multiplying both sides by x gives us:
(7 = 833/x) * x
7x = 833
Dividing both sides by 7 gives us:
(7x = 833) / 7
x = 119
Thus, 119 is the value of x when y = 7.
A 63 sqm. Office space is in need of new tiles for it to resume work. The unit cost of a certain tile is P300 and a labor cost 100% of the materials. How much is the Total cost of the materials and labor?
The total cost of materials and labor for the office space, considering a tile unit cost of P300 and labor cost equal to the materials cost, amounts to P63,000.
To calculate the total cost of materials and labor, we first need to determine the cost of the tiles. Given that the unit cost of a certain tile is P300, we can multiply this by the area of the office space to find the total cost of the tiles. The office space has an area of 63 sqm, so the total cost of the tiles is P300 * 63 = P18,900.
Next, we need to calculate the labor cost, which is 100% of the materials cost. Since the materials cost is P18,900, the labor cost will be equal to P18,900. Therefore, the total cost of labor is also P18,900.
To find the total cost of materials and labor, we add the cost of the tiles (P18,900) and the labor cost (P18,900): P18,900 + P18,900 = P37,800.
Therefore, the total cost of materials and labor for the office space is P37,800.

Julissa has 15 stamps and Ethan has 14 stamps. Pawel has three times the number of stamps as Julissa and Ethan combined. Julissa thinks that 100 is a reasonable estimate for the number of stamps that Pawel has.
What is an estimate of the number of stamps that Pawel has? Is 100 a reasonable total?
32; 100 is a reasonable total
90; 100 is a reasonale estimate
213; 100 is not a reasonale estimate
630; 100 is not a reasonale estimate
Answer:
B. 90; 100 is a reasonable estimate
