The current would be 1.5 feet per second fast at a depth of two feet

Drawing the line of best fit, we have the following points

(0, 1.8) and (10, 0.5)

The equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 1.8

Using the points, we have

10m + 1.8 = 0.5

So, we have

m = -0.13

So, the equation is

y = -0.13x + 1.8

At two feet deep, we have

y = -0.13 * 2 + 1.8

Evaluate

y = 1.54

Approximate

y = 1.5

Hence, the velocity is 1.5 feet per second

The function f(z) is analytic.

Given u(x,y) = x⁴ - 6x²y² + y⁴ + x.

Firstly, let's check whether the given function is harmonic or not. A function u(x, y) is said to be harmonic if it satisfies the Laplace equation. i.e.,

∂²u/∂x² + ∂²u/∂y² = 0.

So, let's find the second-order partial derivatives of u to x and y.

∂u/∂x = 4x³ - 12xy² + 1

∂²u/∂x² = 12x² - 12y²

∂u/∂y = -12x²y + 4y³

∂²u/∂y² = -12x² + 12y²

Therefore,

∂²u/∂x² + ∂²u/∂y² = 12x² - 12y² - 12x² + 12y² = 0

Since f(z) is analytic, it must satisfy the Cauchy-Riemann equations:

u/∂x = ∂v/∂ and

∂u/∂y = -∂v/∂x

We have

∂u/∂x = 4x³ - 12xy² + 1.

So,

∂v/∂y = 4x³ - 12xy² + 1

∫∂v = ∫(4x³ - 12xy² + 1) dy

∂v/∂y = 4x³y - 4y³ + y

∴ v(x, y) = x⁴ - 4x²y² + y² + xy + C, where C is an arbitrary constant. So, the corresponding v(x, y) is given by v(x, y) = x⁴ - 4x²y² + y² + xy + C.

Therefore, the function f(z) is analytic.

The given statement is False. A test statistic based on point estimation is not used to construct the decision rule which defines the rejection region.

In hypothesis testing, a test statistic is calculated using sample data and a specific hypothesis to assess the strength of evidence against the null hypothesis. The decision rule, which determines whether to reject or fail to reject the null hypothesis, is based on the test statistic's distribution under the null hypothesis, rather than the point estimate itself.

The construction of the decision rule involves selecting a significance level (alpha), which represents the probability of rejecting the null hypothesis when it is actually true. The rejection region is determined based on the chosen significance level and the distribution of the test statistic. If the calculated test statistic falls within the rejection region, the null hypothesis is rejected; otherwise, it is not rejected.

Point estimation, on the other hand, is used to estimate an unknown parameter of interest, such as the population mean or proportion, based on sample data. It involves calculating a single value (point estimate) that represents the best guess for the parameter value. The point estimate is not directly involved in constructing the decision rule or defining the rejection region in hypothesis testing.

False. A test statistic based on point estimation is not used to construct the decision rule that defines the rejection region.

The process of hypothesis testing involves constructing a decision rule to determine whether to accept or reject a null hypothesis based on sample data. The decision rule is typically defined using a critical region or rejection region, which is a range of values for the test statistic.

Point estimation, on the other hand, is a method used to estimate an unknown population parameter based on sample data. It involves calculating a single value (point estimate) that serves as an estimate of the population parameter.

While point estimation and hypothesis testing are both important concepts in statistics, they serve different purposes. Point estimation is used to estimate population parameters, whereas hypothesis testing involves making decisions based on sample data.

The decision rule for hypothesis testing is typically constructed based on the significance level (alpha) and the distribution of the test statistic, such as the t-distribution or the standard normal distribution. The test statistic is calculated using sample data and compared to critical values or calculated p-values to determine whether to reject the null hypothesis.

Therefore, the statement that a test statistic based on point estimation is used to construct the decision rule defining the rejection region is false.

The number of pounds would 12 bearings weigh are 26.39615 pounds.

A ratio in mathematics represents the number of times one number contains another. For instance, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the lemon-to-orange ratio is 6:8 (or 3:4), while the orange-to-fruit ratio is 8:14. (or 4:7).

Ratios are mathematical expressions that compare two numbers by dividing them. If you want to compare one data point (A) to another (B), your formula is A/B.

Machine                       Weigh

 1          --------------->    1 kg=2.20462 pounds

 7         ---------------->   15.4 pounds

The solution to the system is (x,y) = (48,19).

To find the solutions to the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the two expressions for y equal to each other and solve for x:

2/3x−5 = 1/2x+3

Multiplying both sides by 6 (the least common multiple of 3 and 2) to clear the fractions, we get:

4x - 30 = 3x + 18

Simplifying, we get:

x = 48

Now that we know x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:

y = 2/3(48) - 5 = 19

So the solution to the system is (x,y) = (48,19).

Since there is exactly one solution, the answer is (D) 1 solution.

Therefore, the value of a is 2, and the value of b is -1. Hence, the coordinates of point Q are (2, -1).

To find the value of a and b, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) are given by:

((x₁ + x₂) / 2, (y₁ + y₂) / 2)

In this case, we are given that the midpoint is (-2, -3), and one of the endpoints is P(-6, -5). Let's denote the coordinates of the other endpoint Q as (a, b).

Using the midpoint formula, we can set up the following equations:

(-6 + a) / 2 = -2 (for the x-coordinate)

(-5 + b) / 2 = -3 (for the y-coordinate)

Let's solve these equations to find the values of a and b:

Equation 1: (-6 + a) / 2 = -2

Multiply both sides by 2:

-6 + a = -4

Add 6 to both sides:

a = 2

Equation 2: (-5 + b) / 2 = -3

Multiply both sides by 2:

-5 + b = -6

Add 5 to both sides:

b = -1

Answer:

1/12 of the lasagna was left

Step-by-step explanation:

To find out how much of the lasagna has been eaten, you have to find the least common denominator (LCD) for the three fractions. The LCD of 1/3, 1/4, and 1/6 is 12 (3x4x6). Now convert all the fractions so that all of their denominators is equal to 72 (1/3=4/12, 1/4=3/12, 1/6=2/12), then add all of the fractions together (4/12 + 3/12 +2/12 = 3/4). 3/4 of the lasagna has been eaten and the remaining lasagna is 1/12 (1-3/4=4/4-3/4).

Answer:

\(\frac{1}{4}\) of the lasagna

Step-by-step explanation:

\(\frac{1}{4} +\frac{1}{6}+ \frac{1}{3}\)

4 = 2 × 2

3 = 3

6 = 2 × 3

LCM = 2 × 2 × 3

LCM = 12

4 × 3 × 6 = 72

\(\frac{18}{72} +\frac{12}{72}+ \frac{24}{72}\)

\(\frac{18+12+24}{72}\)

\(\frac{54}{72}\)

54 = 2 × 3 × 3 × 3

72 = 2 × 2 × 2 × 3 × 3

GCF = 2 × 3 × 3

GCF = 18

\(\frac{\frac{54}{18} }{\frac{72}{18} }=\frac{3}{4}\)

The equivalent equation to the (x² - 5)² - 3x² + 15 = -2 in form of 'm' is given by option c.  m² -3m + 2 = 0.

The equation is equal to,

(x² - 5)² - 3x² + 15 = -2

let the value of m be equals to x² - 5.

Simplify the equation we have,

⇒ ( x² - 5 )² - 3x² + 15 = -2

Take '3' common factor from the 3x² + 15 so that it get convert into x² - 5 we get,

⇒ ( x² - 5 )² - 3 (x² - 5 )  = -2

Now replace x² - 5 by m to get the equivalent equation,

⇒ ( m )² - 3 (m ) = -2

⇒ m² -3m + 2 = 0

Therefore, the equivalent equation to the given equation is written as option c.  m² -3m + 2 = 0.
