Explain in your own words when it is best to solve a system using analytical methods versus using graphical or algebraic methods.
Answers
Answer:
Analytical methods are the preferred way to determine the outcome of a hypothesis when associated equations are simple and a precise answer is desired.
The algebraic method is more precise. When you "solve" a system you are really identifying the points that all of the lines have in common. In other words, the point at which the lines intersect. Finding the solution with graphs is not precise, but should usually be close enough if that is what is asked.

You want to buy some noodles. A 7-ounce package costs $2.17. A 16-ounce package costs $4.64. An 18-ounce package costs $5.76. Which package is the best buy? The -ounce package of noodles is the best buy.
Answers
$2.17/7 = $0.31 for 1-ounce
for 16-ounce package :
$4.64/16 = $0.29 for 1-ounce
for 18-ounce package :
$5.76/18 = $0.32 for 1-ounce
hence, the 16-ounce package of noodles is the best buy.

Easy Points!!!! What net force is required to accelerate a car at a rate of 2 m/s if the car has a mass of 3,000 kg?
Answers
Answer:
[tex]\boxed {\boxed {\sf 6,000 \ Newtons}}[/tex]
Step-by-step explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F= m*a[/tex]
The mass of the car is 3,000 kilograms and the acceleration is 2 meters per second squared.
[tex]m=3,000 \ kg \\a= 2 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 3,000 \ kg * 2 \ m/s^2[/tex]
Multiply.
[tex]F=6,000 \ kg*m/s^2[/tex]
1 kg*m/s² is equal to 1 Newton (N). Therefore, our answer of 6,000 kg*m/s² is equal to 6,000 Newtons.
[tex]F= 6,000 \ N[/tex]
The force required is 6,000 Newtons
Mass = 3,000 kg
Acceleration = 2 m/s^2
To Find:The net force.
Formula:Force = Mass × Acceleration
Explanation:Force = 3,000 kg × 2 m/s^2
Force = 6,000 kg × m/s^2
We know that kg × m/s^2 = Newton.
Hence, the net force required is 6,000 N.
6,000 N is the correct answer.

Answers
Answer:
Domain of inverse: [tex]x \le -1[/tex]
Range of inverse: [tex]y \ge 0[/tex]
Explanation:
The domain and range swap. This is because the inputs (x) and outputs (y) swap roles when going from the original function to the inverse, and vice versa.
Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income.
Answers
Answer:
The smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.
Step-by-step explanation:
The complete question is:
The mean salary of people living in a certain city is $37,500 with a standard deviation of $2,103. A sample of n people will be selected at random from those living in the city. Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income. Round your answer up to the next largest whole number.
Solution:
The (1 - α)% confidence interval for population mean is:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
The margin of error for this interval is:
[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
The critical value of z for 90% confidence level is:
z = 1.645
Compute the required sample size as follows:
[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
[tex]n=[\frac{z_{\alpha/2}\cdot\sigma}{MOE}]^{2}\\\\=[\frac{1.645\times 2103}{500}]^{2}\\\\=47.8707620769\\\\\approx 48[/tex]
Thus, the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.

If you draw a single card once from a deck of ordinary laying cards, what is the probability that it will be a 3 or a black card
Answers
Answer:
The required probability = 0.5385
Step-by-step explanation:
The no. of cards in a deck = 52
The event of having 3 in a draw of a single card = 4/52
The event of having a black card in a draw of a single card = 26/52
The event of having a black card and 3s = 2/52
Let T represent the event of having 3.
U to represent the event of having a black card; &
V to represent the event of having a black card that is 3s
Then the probability that it will be a 3 or a black card is;
P( T or U) = p(T) + p(U) - p(T and U)
P( T or U) = 4/52 + 26/52 - 2/52
P( T or U) = (4+26-2)/52
P( T or U) = 28/52
P( T or U)= 7/13
P( T or U) = 0.5385
