An Experiment is repeated 10 times compared to just 3 times, the results from the 10 repetitions would generally be considered more reliable.
True.
In general, conducting an experiment multiple times increases the reliability of the results. The more times an experiment is repeated, the greater the opportunity to collect data and observe patterns or trends. This allows for a more robust analysis and reduces the impact of random variations or errors that may occur in a single trial.
When an experiment is repeated multiple times, it helps to reduce the effects of outliers or anomalies that may occur in a single trial. By averaging the results over multiple repetitions, the overall outcome tends to be more representative and reliable.
In the context of statistical analysis, increasing the sample size (number of repetitions) can lead to more precise estimates of parameters and reduce the margin of error. It provides a better understanding of the underlying phenomenon being studied and allows for more confident conclusions.
Therefore, if an experiment is repeated 10 times compared to just 3 times, the results from the 10 repetitions would generally be considered more reliable. The larger sample size provides a stronger basis for drawing conclusions and making inferences about the population or phenomenon under study.

Tito purchased sandwiches and a gallon of milk for himself and his friends. Each sandwich cost $9. The gallon of milk cost $6. The total cost of the meal was $33. the equation for x, the number of sandwiches that Tito purchased? *
Answer:
answer SHOULD be 3 sandwiches
Step-by-step explanation:
33-6=27÷9=3
Answer:
9x + 6 = 33; 3
Step-by-step explanation:
9x + 6 represents the number of sandwiches and gallon of milk Tito purchased. 33 represents the total cost of the sandwiches and milk. Using this equation, we can solve to find x (the number of sandwiches purchased). Therefore, x = 3.
solve for x,y, and z.
The given triangle is isosceles, so the two remaining angles in the triangle both have measure xº. The interior angles of any triangle sum to 180º, so that
58º + xº + xº = 180º
58 + 2x = 180
2x = 122
x = 61
Angles y and z are supplementary to angle x, so that
xº + yº = 180º
and
xº + zº = 180º
and consequently, y = z. In particular, we get
y = 180 - 61
y = 119
and so
z = 119

You are managing a division of a large company. The marketing department submits a report to you about the demand for the product you manage.
The report includes the following estimated demand function:

(100. 4)
3. 2)
(0. 012)
(1. 0)
Using this demand function, you can analyze the impact of price, income, and other factors on the demand for your product and make informed decisions regarding pricing and marketing strategies.
The estimated demand function provided in the report for the product you manage is as follows:
Qd = 2,910 - 11.3P + 0.050INCOME - 3.0Pother(100.4)^3.2(0.012)(1.0)
This demand function represents the relationship between the quantity demanded (Qd) of your product and several variables: the price of your product (P), the income of consumers (INCOME), and other factors (Pother).
The coefficients associated with each variable represent the impact of that variable on the quantity demanded.
For instance:
A decrease in the price of your product (P) by 1 unit would result in an increase in the quantity demanded (Qd) by 11.3 units.An increase in consumer income (INCOME) by 1 unit would result in an increase in the quantity demanded (Qd) by 0.050 units.
Other factors (Pother) affect the quantity demanded, but the specific details of these factors are not provided in the given equation.The numbers in parentheses and exponent notation indicate the mathematical operations involved.

Find the equilibrium quantity.
hundred units
Find the equilibrium price.
the equilibrium quantity is 20 hundred units and the equilibrium price is $89.
The weekly demand and supply functions for Sportsman 5 X 7 tents can be represented as:
p = 0.1x² - x + 69 (Demand Function) and
p = 0.1x² + 2x + 49 (Supply Function)
We can find the equilibrium quantity by equating both functions:
Demand Function = Supply Function
0.1x² - x + 69 = 0.1x² + 2x + 49- x - 2x
= 49 - 69-x = -20x = 20
On substituting the value of x in any of the above functions, we can get the equilibrium price:
p = 0.1x² - x + 69
= 0.1(20)² - (20) + 69 = $89
Therefore, the equilibrium quantity is 20 hundred units and the equilibrium price is $89.

Subtract 108 from 180 to get angle VTU (since its on a straight line, its 180). As for the last angle, add the two up. We would add 72 and and 76 which would give us 148. Now we just subtract this from 180 (this is cuz the angles of a triangle add up to 180). hope this helped :)
Punctele O, A, B, C sunt coliniare în această ordine, iar segmentele OA, AB și BC au lungimile exprimate în cm, prin numere naturale pare consecutive. Se știe că M este mijlocul segmentului AC și OM = 11 cm. Calculați: a) lungimea segmentului OC; b) distanța dintre N, mijlocul segmentului OB, și punctul M.
Răspuns:
a) OC = 18cm
b) MN = 6cm
Explicație pas cu pas:
Găsiți diagrama la întrebarea atașată.
a) Din diagramă se poate observa că OC = OA + AB + AC
OC = 2n + 2n + 2 + 2n + 4
OC = 6n + 6
Următorul este să obțineți valoarea lui n:
OM = OA + AM
Să obținem segmentul AM;
Deoarece M este segmentul mijlociu al AC, atunci;
AM = AC / 2
AM = AB + BC / 2
AM = 2n + 2 + 2n + 4/2
AM = 4n + 6/2
AM = 2n + 3
Din moment ce OM = OA + AM
OM = 2n + 2n + 3
OM = 4n + 3
Dat fiind OM = 11
11 = 4n + 3
4n = 11-3
4n = 8
n = 2
Următorul pas este să calculați OC;
OC = 6n + 6
OC = 6 (2) + 6
OC = 18
Prin urmare, lungimea segmentului OC este de 18 cm
b) Această întrebare ne cere să găsim segmentul de linie MN.
Din diagramă, MN = AM - AN
Deoarece AM = 2n + 3 din întrebarea 1;
AM = 2 (2) +3
AM = 4 + 3
AM = 7
Acum, să obținem AN:
Din diagramă, AN = ON-OA și ON = OB / 2
AN = OB / 2 - OA
AN = (2n + 2n + 2) / 2 - 2n
AN = 4n + 2/2 - 2n
AN = 2n + 1 - 2n
AN = 2n-2n + 1
AN = 1
De la MN = AM - AN
MN = 7 - 1
MN = 6cm
Prin urmare, distanța dintre N, mijlocul segmentului OB și punctul M este de 6cm

the distance from the epicenter of the march 1964 earthquake to crescent city is 2600 kilometers. how long did it take the first p-wave to reach crescent city
The distance from the epicenter of the march 1964 earthquake to crescent city is 2600 kilometers and It took 400 seconds for the first p-wave to reach crescent city
In a seismic event like an earthquake, seismic waves propagate through the Earth at different speeds. The first type of seismic wave to reach a particular location is the primary wave, or P-wave. P-waves are compressional waves that travel faster than other seismic waves, such as S-waves or surface waves.
To calculate the time it took for the P-wave to reach Crescent City, we need to know the speed at which P-waves travel. On average, P-waves travel at a speed of about 6-7 kilometers per second in the Earth's crust. However, this speed can vary depending on the specific properties of the Earth's layers.
Using an average speed of 6.5 kilometers per second, we can calculate the time it took for the P-wave to travel a distance of 2600 kilometers:
Time = Distance / Speed = 2600 km / 6.5 km/s ≈ 400 seconds.
Therefore, it took approximately 400 seconds, or 6 minutes and 40 seconds, for the P-wave to reach Crescent City from the epicenter of the March 1964 earthquake.
It is important to note that the calculated time is an estimation based on average values, and the actual time may vary depending on the specific geological conditions along the propagation path of the P-wave.

Find the value of C that completes the square for x^2-2x + C
Answer:
C = 1.
Step-by-step explanation:
x^2 - 2x = (x - 1)^2 - 1 so:
x^2 - 2x + C = (x - 1)^2 - 1 + C
So to get a perfect square C must be 1 ( as -1 + 1 = 0):-
(x - 1)^2 - 1 + 1 = (x - 1)^2
Checking this:
x^2 - 2x + 1

Explain your reasoning
The expressions are another way to write the following:
(-5-√²+3√3)(-+√3-2-√3) = 12 (NO)
12(6√4 + 3) = 180 (NO)
√√25 = √5 (YES)
[1]^(1/2) = 1 (YES)
[1]^(1/2) + 11 - 14 = -2 (NO)
The expression (-5-√²+3√3)(-+√3-2-√3) is expanded and simplified as follows:
(-5-√²+3√3)(-+√3-2-√3) = (-5)(-) + (-5)(√3) + (-√2)(-) + (-√2)(√3) + (3√3)(-) + (3√3)(√3) + (√3)(-) + (√3)(√3)
= 5 - 5√3 + √6 - √6 - 3√3 + 9 - √3 - 3
= 11 - 8√3.
12(6√4 + 3): By simplifying this expression, we get 12(6√4 + 3) = 12(12 + 3) = 12(15) = 180.
The expression √√25 is simplified as the square root of the square root of 25, which is equal to √5.
The statement "in radical form and all the real cube root of 125" suggests expressing the number 125 in terms of its real cube root, which is 5. Therefore, the expression is equal to 5.
[1]^(1/2): Any nonzero number raised to the power of 1/2 gives its positive square root. Therefore, [1]^(1/2) = √1 = 1.
[1]^(1/2) + 11 - 14: From the previous explanation, we know that [1]^(1/2) = 1. So, the expression simplifies to 1 + 11 - 14 = -2.
