12 hours to cook 5 killigrams how long is needed to cook 3 killograms of meat

Note that the correct answers are :

1. Over the interval [2,3], the   average rate of change of g is lower than that of both f andh.

  - This statement is false.   The average rate of change of g may or may not be lower than that of f and h over the interval [2,3]. It depends on the specific values of f, g,and h at those points.

2. When x >4, the value of h(x) exceeds the values of both g(x) and f(x).

  - This statement   is true.   As x becomes   greater than4, the quadratic function h(x) will  eventually exceed both the linear function g(x) and the exponential function f(x). This is   because the quadratic function grows faster than the linear and exponential functions inthe long run.

3. As x increases on the interval [0, infinity],   the rate of change of g eventually exceeds  the rate of change of both f and h.

  - This statement is   true. The functiong(x) is a linear function   with a constant rate of change,while f(x) and h(x) are exponential and quadratic functions, respectively.

As x increases indefinitely,the rate of change of g will eventually surpass the rate of change of f and h,   which may become relatively slower.

The orientation of the element with respect to the original element is given by the angle (θ) from the x-axis to the principal axis.

To determine the principal strains and the maximum in-plane shear strain, we first need to calculate the principal strains and their orientations. The principal strains represent the maximum and minimum strains experienced by the element.

Given:

εx = -310 × 10⁻⁶

εy = 0

γxy = 150 × 10⁻⁶

To find the principal strains, we need to solve the equation for the characteristic equation:

λ² - (εx + εy)λ + εxεy - γxy² = 0

Plugging in the given values:

λ² - (-310 × 10⁻⁶ + 0)λ + (-310 × 10⁻⁶ × 0) - (150 × 10⁻⁶)² = 0

Simplifying the equation:

λ² + 310 × 10⁻⁶λ + (150 × 10⁻⁶)² = 0

We can solve this quadratic equation to find the values of λ, which represent the principal strains.

Using the quadratic formula:

λ = (-b ± √(b² - 4ac)) / (2a)

a = 1

b = 310 × 10⁻⁶

c = (150 × 10⁻⁶)²

Calculating λ:

λ = (-310 × 10⁻⁶ ± √((310 × 10⁻⁶)² - 4(1)(150 × 10⁻⁶)²)) / (2(1))

λ = (-310 × 10⁻⁶ ± √((96100 × 10⁻¹²) - (4)(22500 × 10⁻¹²))) / 2

λ = (-310 × 10⁻⁶ ± √((96100 - 90000) × 10⁻¹²)) / 2

λ = (-310 × 10⁻⁶ ± √(6100 × 10⁻¹²)) / 2

λ = (-310 × 10⁻⁶ ± 78.189 × 10⁻⁶) / 2

Now we can calculate the values of λ:

λ₁ = (-310 × 10⁻⁶ + 78.189 × 10⁻⁶) / 2

= -231.805 × 10⁻⁶

λ₂ = (-310 × 10⁻⁶ - 78.189 × 10⁻⁶) / 2

= -193.595 × 10⁻⁶

Therefore, the principal strains are:

ε₁ = -231.805 × 10⁻⁶

ε₂ = -193.595 × 10⁻⁶

The maximum in-plane shear strain (γmax) can be calculated using the formula:

γmax = (ε1 - ε2) / 2

γmax = (-231.805 × 10⁻⁶ - (-193.595 × 10⁻⁶)) / 2

= -19.105 × 10⁻⁶

The average normal strain (εavg) is the average of the principal strains:

εavg = (ε₁ + ε₂) / 2

εavg = (-231.805 × 10⁻⁶ + (-193.595 × 10⁻⁶)) / 2

= -212.7 × 10⁻⁶

Now let's determine the orientations of the corresponding elements.

Therefore, The orientation of the element with respect to the original element is given by the angle (θ) from the x-axis to the principal axis.

To do this, we will combine the terms that are alike and simplify them.

That is multiply the integers with the integers and the algebraic term with the algebraic term.

Apply the addition law of indices:

That is the answer.

The estimate of the mean length of the insects Ciara found is 17 millimeters (mm).

To calculate an estimate of the mean length of the insects Ciara found, we need to find the weighted average of the lengths using the given frequencies.

Let's denote the lower limits of the length intervals as L1 = 0, L2 = 10, and L3 = 20.

Similarly, denote the upper limits as U1 = 10, U2 = 20, and U3 = 30.

Next, we calculate the midpoints of each interval by taking the average of the lower and upper limits.

The midpoints are M1 = (L1 + U1) / 2 = 5, M2 = (L2 + U2) / 2 = 15, and M3 = (L3 + U3) / 2 = 25.

Now, we can calculate the sum of the products of the frequencies and the corresponding midpoints.

This gives us (5 \(\times\) 5) + (6 \(\times\) 15) + (9 \(\times\) 25) = 25 + 90 + 225 = 340.

Next, we calculate the sum of the frequencies, which is 5 + 6 + 9 = 20.

Finally, we divide the sum of the products by the sum of the frequencies to find the weighted average, which is 340 / 20 = 17.

Therefore, the estimate of the mean length of the insects Ciara found is 17 millimeters (mm).

Thus, the mean length of the insects Ciara found is approximately 17 millimeters (mm).

Answer:12

Step-by-step explanation:

The given statement in the following question about factors are constant, correlation is False.

A correlation coefficient (r) measures the strength and direction of the linear relationship between two variables. The value of r ranges between -1 and 1. A positive value of r indicates a positive linear relationship, while a negative value of r indicates a negative linear relationship.

The magnitude (absolute value) of r measures the strength of the relationship, with values closer to 1 indicating a stronger relationship. Therefore, an r value of -0.85 indicates a stronger relationship than an r value of 0.68.

However, it is important to note that the strength of the relationship does not necessarily mean that the predictions will be more accurate.

The accuracy of predictions depends on several other factors, such as the sample size, the variability of the data, the presence of outliers, and the appropriateness of the model used for prediction.

The probability of getting exactly 417 girls in 811 births is approximately 0.0668.

The probability of getting 417 or more girls in 811 births is approximately 0.1349.

a. The probability of getting exactly 417 girls in 811 births is not 1. The correct probability can be calculated using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n is the total number of births, k is the number of girls, p is the probability of a girl birth (assumed to be 0.5 for simplicity), and "n choose k" denotes the binomial coefficient, which is calculated as:

(n choose k) = n! / (k! * (n-k)!)

Plugging in the values, we have:

P(X = 417) = (811 choose 417) * 0.5^417 * 0.5^(811-417)

Using a calculator or software, we can simplify and evaluate this expression to find:

P(X = 417) ≈ 0.0668

So the probability of getting exactly 417 girls in 811 births is approximately 0.0668.

b. To find the probability of getting 417 or more girls in 811 births, we need to calculate the cumulative probability from 417 to 811:

P(X ≥ 417) = P(X = 417) + P(X = 418) + ... + P(X = 811)

We can use software or a calculator to calculate this sum, or we can use the complement rule:

P(X ≥ 417) = 1 - P(X < 417)

To calculate P(X < 417), we can use the cumulative distribution function (CDF) of the binomial distribution:

P(X < 417) = sum(i=0 to 416) (811 choose i) * 0.5^i * 0.5^(811-i)

Again, using software or a calculator, we can evaluate this expression to find:

P(X < 417) ≈ 0.8651

So the probability of getting 417 or more girls in 811 births is:

P(X ≥ 417) = 1 - P(X < 417) ≈ 1 - 0.8651 ≈ 0.1349

Rounding to four decimal places, the probability of getting 417 or more girls in 811 births is approximately 0.1349.

a) Timothy's bike costs $20.It's important to note that the given percentage value represents a proportion or fraction of the original cost, allowing us to calculate the specific cost

To find the cost of Timothy's bike, we need to calculate 20% of Katie's bike cost.

20% of $100 can be calculated by multiplying $100 by 0.20:

20% * $100 = $20.

Therefore, Timothy's bike costs $20.

To calculate 20% of $100, we multiply $100 by the decimal equivalent of 20%, which is 0.20:

20% * $100 = 0.20 * $100 = $20.

In this scenario, Timothy's bike is priced at 20% of Katie's bike cost. This means that Timothy's bike is relatively less expensive compared to Katie's bike. It's important to note that the given percentage value represents a proportion or fraction of the original cost, allowing us to calculate the specific cost of Timothy's bike based on the given percentage relationship.
