There are a total of 5 different routes that Tanya can take. Of the 5 routes, 2 of them take 30 minutes. So we divide 2 by 5 to get 0.40. To get a decimals, we need to move the decimal over to the right 2 places. So the answer is C. 40%. I hope this was helpful and if so, please leave a good rating and thanks and maybe even brainliest answer. Thank you and I really appreciate it. Have a nice day!

respond to the following in a minimum of 175 of your own words: how would you explain the differences between the trapezoidal ru
harkovskaia [24]

The differences between the trapezoidal rule and simpson's rule is -

The trapezoidal rule and Simpson's method, the latter a set of formulas of varying complexity, are both Newton-Cotes formulas, that are used to examine and model complex curves.

<h3>What is trapezoidal rule?</h3>

The trapezoidal rule is just an integration rule that divides a curve into small trapezoids to calculate the area under it. A area under the curve is calculated by adding the areas of all the small trapezoids.

Follow the steps below to use the trapezoidal rule to determine the area under given curve, y = f. (x).

  • Step 1: Write down the total number of sub-intervals, "n," as well as the intervals "a" and "b."
  • Step 2: Use the formula to determine the width of the sub-interval, h (or) x = (b - a)/n.
  • Step 3: Use the obtained values to calculate this same approximate area of a given curve, ba f(x)dx Tn = (x/2) [f(x0) + 2 f(x1) + 2 f(x2) +....+ 2 f(n-1) + f(n)], where xi = a + ix
<h3>What is Simpson's method?</h3>

Simpson's rule is used to approximate the area beneath the graph of the function f to determine the value of the a definite integral (such that, of the form  b∫ₐ f(x) dx.

Simpson's 1/3 rule provides a more precise approximation. Here are the steps for using Simpson's rule to approximate the integral ba f(x) dx.

  • Step 1: Figure out the values of 'a' & 'b' from interval [a, b], as well as the value of 'n,' which represents the number of subintervals.
  • Step 2: Determine the width of every subinterval using the formula h = (b - a)/n.
  • Step 3: Using the interval width 'h,' divide this same interval [a, b] [x₀, x₁], [x₁, x₂], [x₂, x₃], ..., [xn-2, xn-1], [xn-1, xn] into 'n' subintervals.
  • Step 4: In Simpson's rule formula, substitute all of these values and simplify. b∫ₐ f(x) dx ≈ (h/3) [f(x0)+4 f(x1)+2 f(x2)+ ... +2 f(xn-2)+4 f(xn-1)+f(xn)].

Thus, sometimes we cannot solve an integral using any integration technique, and other times we don't have a particular function to integrate. Simpson's rule aids in approximating the significance of the definite integral in such cases.

A box of oat cereal cost $3.90 for 15 oz.A box of rice cereal cost $3.30 for 11 oz which box of cereal costs less per ounce use
mariarad [96]

Answer:

A box of oat cereal cost lees than a box of rice cereal cost per ounce.

Step-by-step explanation:

Given:

15 oz of oat cereal cost = $3.90

11 oz of rice cereal cost = $3.30

We need to find the which box of cereal cost less per ounce.

Solution.

First we will find cost of 1 oz of oat cereal.

Now we know that;

15 oz of oat cereal cost = $3.90

1 oz of oat cereal cost = cost of 1 oz of oat cereal.

By Using Unitary method we get;

cost of 1 oz of oat cereal = \frac{3.90}{15} = \$0.26

Now we will find cost of 1 oz of rice cereal.

Now we know that;

11 oz of rice cereal cost = $3.30

1 oz of rice cereal cost = cost of 1 oz of rice cereal.

By Using Unitary method we get;

cost of 1 oz of rice cereal = \frac{3.30}{11} = \$0.3

Now from above we can see that cost of 1 oz of oat cereal is $0.26 and cost of 1 oz of rice cereal is $0.3.

Hence we say that, A box of oat cereal cost lees than a box of rice cereal cost per ounce.
