A technology manufacturer must test a sample of smartphones to ensure that quality and safety standards are met. Which of these methods will produce the most representative sample of the population of smartphones made by this company?
Answers
The condition where the manufacturer tests every 500th smartphone off the production line, is the method that will produce the most representative sample of the population of smartphones made by this company. Therefore, the correct answer is option D.
This method involves selecting smartphones at regular intervals, regardless of when they are produced or what day of the week it is. By selecting every 500th smartphone, the sample will be more likely to represent the entire smartphone population produced by the company. This method is also efficient and cost-effective since the manufacturer does not need to test every single smartphone.
The other options have potential drawbacks that may make them less representative.
Testing only the first smartphone off the production line each day (option A) may not be representative of variations in the production process causing the first smartphone to be different from the rest. Testing only the last 1000 smartphones produced each month (option B) may also not be representative if there are variations in production processes that occur over longer periods. Testing every smartphone made on Wednesday (option C) may not be representative of variations in the production process occurring over different days of the week.Know more about sample and population,

Answers
If Jane and Sarah share an amount of £63 and Jane receives "5/9" of money, then the amount of money Sarah receives is £28..
The total amount that needs to be shared between Jane and Sarah is = £63,
We know that , Jane receives "5/9" of the total amount,
Which means , Jane receives = (5/9)×63 = £35,
The total-sum of money is = £63,
So, We can write,⇒ Total money = Jane + Sarah,
Substituting the values ,
We get,
⇒ 63 = 35 + Sarah,

Solve this word problem: Hamburgers come in packs of 10. Hamburger buns come in packs of 8. What is the smallest amount of each I could purchase if I wanted to have the same amount of both hamburgers and buns?
Answers
Using LCM we would need to purchase 4 packs of hamburgers and 5 packs of buns to have the same amount of both.
To solve this word problem and find the smallest amount of hamburgers and buns you could purchase to have the same amount of both, we need to determine the least common multiple (LCM) of the pack sizes (10 for hamburgers and 8 for buns).
Step 1: List the multiples of each pack size.
- Multiples of 10: 10, 20, 30, 40, 50, ...
- Multiples of 8: 8, 16, 24, 32, 40, ...
Step 2: Identify the least common multiple.
- The LCM of 10 and 8 is 40.
So, the smallest amount of each you could purchase to have the same amount of hamburgers and buns is to buy 4 packs of hamburgers (4 x 10 = 40) and 5 packs of buns (5 x 8 = 40).

how many 6-person lineups can be formed from a volleyball roster of 12 players, assuming every player can play any position?
Answers
Answer:2
Step-by-step explanation:
12/6=2
There are 924 possible outcomes 6-person lineups that can be formed from a volleyball roster of 12 players, assuming every player can play any position.
To answer your question, we can use the combination formula which is nCr = n!/(r!(n-r)!), where n is the total number of players in the roster and r is the number of players we want to choose for the lineup. In this case, we want to choose 6 players for the lineup out of 12 players in the roster. So, the formula becomes 12C6 = 12!/(6!(12-6)!) = 924. Therefore, there are 924 possible 6-person lineups that can be formed from the volleyball roster of 12 players, assuming every player can play any position.
To form a 6-person lineup from a 12-player volleyball roster, you can use the concept of combinations. Combinations are used to find the number of ways to choose items from a larger set without considering the order of the items. In this case, you need to choose 6 players from a set of 12. The formula for combinations is:
C(n, k) = n! / (k!(n-k)!)
where C(n, k) is the number of combinations, n is the total number of items, k is the number of items to choose, and ! denotes the factorial of a number. Plugging in the values for your question:
C(12, 6) = 12! / (6!(12-6)!)
C(12, 6) = 12! / (6!6!)
C(12, 6) = 924
So, there are 924 possible outcomes 6-person lineups that can be formed from a volleyball roster of 12 players, assuming every player can play any position.

An airplane flies 1062 km with the wind. In the same amount of time it can fly 738 km against the wind. The speed of the plane in still air is 200km/h. Find The speed of the wind
Answers
The speed of the wind is approximately 18.8 km/h.
Now, let's use the information we have to set up some equations. We know that the distance the airplane can fly with the wind is 1062 km, and that it covers this distance in the same amount of time as it takes to fly 738 km against the wind. We can use the formula:
distance = speed x time
to write equations for these situations. For example, when flying with the wind:
1062 = (200 + w) x time
And when flying against the wind:
738 = (200 - w) x time
Now, we can solve for the unknown variable, which in this case is the speed of the wind. Let's rearrange the first equation to solve for time:
time = 1062 / (200 + w)
And the second equation:
time = 738 / (200 - w)
Since the time for each trip is the same, we can set these two expressions equal to each other and solve for w:
1062 / (200 + w) = 738 / (200 - w)
To solve for w, we can cross-multiply and simplify:
1062(200 - w) = 738(200 + w)
212400 - 1062w = 147600 + 738w
3442w = 64799

The following graph describes function 1, and the equation below it describes function 2. Determine which function has a greater maximum value, and provide the ordered pair.
Function 1 graph of function f of x equals negative x squared plus 8 multiplied by x minus 15
Function 2 f(x) = −x2 + 4x + 1
A Function 1 has the larger maximum at (4, 1).
B Function 1 has the larger maximum at (1, 4).
C Function 2 has the larger maximum at (2, 5).
D Function 2 has the larger maximum at (3, 2).
Answers
Function 2 has the larger maximum at (2, 5).
Hence the correct option is (C).
Given the first function is,
Function 1: f(x) = x² + 8x - 15
Differentiating the function with respect to 'x' we get,
f'(x) = 2x + 8
f''(x) = 2
Now, f'(x) = 0 gives
2x + 8 = 0
2x = -8
x = -8/2
x = -4
At x = -4 the value of f''(-4) = 2 > 0
So there is minimum at x = -4.
Second function is:
Function 2: f(x) = -x² + 4x + 1
Differentiating the function with respect to 'x' we get,
f'(x) = -2x + 4
f''(x) = -2
Now, f'(x) = 0 gives
-2x + 4 = 0
2x = 4
x = 4/2
x = 2
At x =2 the value of f''(2) = -2 < 0
So at x = 2 the function has maximum value.
max f(x) = f(2) = - 2² + 4*2 + 1 = - 4 + 8 + 1 = 5
So function 2 has the larger maximum at (2, 5).
Hence the correct option is (C).

Las dos ruedas traseras de un tractor tienen un perímetro 90 cm mayor que las delanteras. En un camino de 230 metros, las ruedas traseras giran 36 veces menos que las ruedas delanteras. ¿Cuál es el perímetro de las ruedas?
Answers
Sabemos que en un camino de 230 metros, las ruedas delanteras giran 36 veces más que las traseras. Esto significa que la distancia recorrida por las ruedas delanteras es 36 veces mayor que la distancia recorrida por las traseras en ese camino. Por lo tanto:
36(x + 90) = 23000
Resolviendo para x, obtenemos:
x + 90 = 23000/36
x + 90 = 638.89
x = 548.89
Por lo tanto, el perímetro de las ruedas delanteras es de 548.89 cm, y el perímetro de las ruedas traseras es x + 90 = 638.89 cm.
Find the weighted average of the numbers 1 and 6, with a weight of two-thirds on the first number and one-third on the second number. A. 3.5 B. 3.3 C. 2.7 D. 2.4
Answers
The weighted average is 1.
Weighted average is a statistical term used to describe a average calculated by giving different weights to different elements in a set of values.
The weighted average of the numbers -1 and 5 with two thirds of the weight on the first number and one third on the second number is 0.67.
The formula for a weighted average is:
(Weight1 * Value1) + (Weight2 * Value2) / (Weight1 + Weight2)
Where Weight1 is the weight for the first value (-1), Value1 is the first value (-1), Weight2 is the weight for the second value (5), and Value2 is the second value (5).
In this case, Weight1 = 2/3, Weight2 = 1/3, Value1 = -1, and Value2 = 5. Plugging these values into the formula, we get:
(2/3 * -1) + (1/3 * 5) / (2/3 + 1/3) = (-2/3 + 5/3) / 1 = 3/3 = 1
Hence, the weighted average is 1.

Answers
it would take 7.5 gallons of paint to cover 2000 square feet of surface.
What is an Equations?
Equations are mathematical statements with two algebraic expressions on either side of an equals (=) sign. It illustrates the equality between the expressions written on the left and right sides. To determine the value of a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.
The proportion that can be used to find the number of gallons of paint needed to cover 2000 square feet of surface is:
3 gallons : 800 square feet = x gallons : 2000 square feet
where x is the number of gallons of paint needed to cover 2000 square feet of surface.
Simplifying the proportion, we can cross-multiply to get:
3 * 2000 = 800 * x
Solving for x, we get:
x = (3 * 2000) / 800 = 7.5 gallons
Therefore, it would take 7.5 gallons of paint to cover 2000 square feet of surface.
