Subsitute the required values,

\(\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{4^{2}}{2}}}}\)

\(\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{16}{2}}}}\)

\(\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{8}}}\)

\(\sf{ = }{\sf{\dfrac{176}{7}}}\)

\(\bold{ = 25.142\: in.^{2}}\)

Area of parallelogram

\(\bold{\red{ = Base }}{\bold{\red{\times{ Height }}}}\)

Subsitute the required values,

\(\sf{ = 10 }{\sf{\times{ 6 }}}\)

\(\bold{ = 60 \:in.^{2}}\)

Thus, The area of parallelogram is 60 in.

Area of the given figure

= Area of semicircle + Area of parallelogram

Subsitute the required values,

\(\sf{ = 25.142 + 60 }\)

\(\sf{ = 85.142\: in^{2}. }\)

When round off to nearest Hundred

\(\bold{ = 85.1 in.^{2}}\)

Hence, The area of the given figure is 85.1 inches² .

The area of the composite figure to the nearest hundredth is 85.12 inches squared.

The area can be defined as the space occupied by a flat shape or the surface of an object.

Therefore, the figure is a composite figure, it has a parallelogram and a semi circle.

area of the figure = area of parallelogram + area of semi circle

area of parallelogram = bh

where

b = 10 inches

h = 6 inches

area of parallelogram = 10 × 6 = 60 inches²

area of semi circle = πr²  / 2

where

Therefore,

r = 8 / 2 = 4 inches

area of semi circle = 3.14 × 4² / 2

area of semi circle = 3.14 × 16 / 2

area of semi circle = 50.24 / 2

area of semi circle = 25.12 inches²

area of the figure = 60 + 25.12 = 85.12 inches²

The diameter of a circle is defined as being twice the length of its radius.

If SU = 16.2 centimeters then the value of RT = 8.1 cm.

The diameter of a circle is defined as being twice the length of its radius. The radius of a circle is measured from the center to one of the circle's endpoints, whereas the diameter is measured from one end of the circle to another end of the circle, passing through the center.

In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.

The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.

Here, SU is the diameter and RT is the radius.

Radius of the circle = 1/2 d

Where d = 16.2 then

substitute the value of d in the above equation, and we get

Radius of the circle  = 1/2 (16.2)

Radius of the circle = 8.1

Therefore, the value of RT = 8.1 cm.

The complete question is:

If SU = 16.2 centimeters, what is RT?

Step-by-step explanation:

calculate the approimate value

Answer:

Black socks pairs = 7

Brown socks pairs = 3

White socks pairs = 8

P(not black) = ?

First, you need to add the brown & white socks pairs,

\(3 + 8 = 11\)

Then you need to add the total number of socks pairs,

\(7 + 3 + 8 \\ = 7 + 11 \\ = 18\)

P(not black)

\( = \frac{11}{18} \)

Step-by-step explanation:

solution given:

total pair of socks[S]=(7+3+8)=18

total pair of black socks[B]=7

total pair of brown socks [C]=3

total pair of white socks[W]=8

total no of orange marbles[O]=2

now

the P( not black) =?

we have

P( not black) =1-\( \frac{n[B]}{n[S]} \)

P( not black) =1-\( \frac{7}{18} \)

P( not black) =\( \frac{18-7}{18} \)

P( not black) =\( \frac{11}{18} \)

so 11/18 is a required probabilty.

Type II errors occur when a researcher retains the null hypothesis when it should be rejected.

Type II errors, also known as false negatives, happen when a researcher fails to reject the null hypothesis when it is actually false. In hypothesis testing, the null hypothesis represents the default assumption or the absence of an effect. The alternative hypothesis, on the other hand, suggests that there is a significant relationship or effect present in the data.

To determine whether to reject or retain the null hypothesis, researchers perform statistical tests based on sample data. When the sample data provides strong evidence against the null hypothesis, the researcher should reject it in favor of the alternative hypothesis. However, in some cases, the sample data may not be sufficiently representative or the statistical test may lack power, leading the researcher to erroneously retain the null hypothesis.

By retaining the null hypothesis when it should be rejected, the researcher commits a Type II error. This means that a true effect or relationship in the population goes unnoticed or is falsely dismissed. Type II errors can have serious consequences, particularly in scientific research or decision-making processes where failing to detect a significant effect can lead to missed opportunities or incorrect conclusions. To minimize the risk of Type II errors, researchers often strive to increase sample sizes, improve experimental designs, or use more powerful statistical tests.

Is the ratio 15:12 equivalent to these? No, it's not equivalent.

Why not? Because if we tripled everything in 5:3 then we'd get 15:9. We don't have the second value as 12.

-------------------------------------

Is the ratio 30:18 equivalent to these? Yes it is equivalent

To go from 5:3 to 30:18, we multiply everything by 6

5*6 = 30

3*6 = 18

This shows that 5:3 scales up to 30:18

-------------------------------------

Give two more examples of ratios that are equivalent to 5:3.

Pick any number you want. Let's say we pick 7. Multiply both parts of 5:3 by the value 7

5*7 = 35

3*7 = 21

The ratio 5:3 is equivalent to 35:21

The ratio 5:3 is also equivalent to 50:30 after multiplying both parts by 10.

1. nβ₀ + β₁Σxi = Σyi

β₀Σxi + β₁Σxi² = Σxiyi

These are simultaneous linear equations in β₀ and β₁. Solving these equations will give us the critical values of β₀ and β₁ that minimize the RSS. The exact solution depends on the specific values of Σxi, Σyi, Σxi², and Σxiyi.

2.  The solution depends on the specific values of Σxi, Σyi, Σ(xi - X), and Σ(xi - X)(yi - α₀ - α₁(xi - X)).

1. To derive the critical values of β₀ and β₁ that minimize the residual sum of squares (RSS) for the sample regression model Yi = β₀ + β₁X₁ + ei, we need to find the partial derivatives of the RSS with respect to β₀ and β₁ and set them equal to zero.

The RSS is defined as the sum of the squared residuals:

RSS = Σ(yi - β₀ - β₁xi)²

To find the critical values, we differentiate the RSS with respect to β₀ and β₁ separately and set the derivatives equal to zero:

∂RSS/∂β₀ = -2Σ(yi - β₀ - β₁xi) = 0

∂RSS/∂β₁ = -2Σ(xi)(yi - β₀ - β₁xi) = 0

Simplifying the above equations, we get:

Σyi - nβ₀ - β₁Σxi = 0

Σxi(yi - β₀ - β₁xi) = 0

Rearranging the equations, we have:

nβ₀ + β₁Σxi = Σyi

β₀Σxi + β₁Σxi² = Σxiyi

These are simultaneous linear equations in β₀ and β₁. Solving these equations will give us the critical values of β₀ and β₁ that minimize the RSS. The exact solution depends on the specific values of Σxi, Σyi, Σxi², and Σxiyi.

2. To derive the critical values of α₀ and α₁ that minimize the RSS for the sample regression model Yi = α₀ + α₁(Xi - X) + ei, we follow a similar approach as in the previous question.

The RSS is still defined as the sum of the squared residuals:

RSS = Σ(yi - α₀ - α₁(xi - X))²

We differentiate the RSS with respect to α₀ and α₁ separately and set the derivatives equal to zero:

∂RSS/∂α₀ = -2Σ(yi - α₀ - α₁(xi - X)) = 0

∂RSS/∂α₁ = -2Σ(xi - X)(yi - α₀ - α₁(xi - X)) = 0

Simplifying the equations, we get:

Σyi - nα₀ + α₁(Σxi - nX) = 0

Σ(xi - X)(yi - α₀ - α₁(xi - X)) = 0

Again, these are simultaneous linear equations in α₀ and α₁. Solving these equations will give us the critical values of α₀ and α₁ that minimize the RSS. The solution depends on the specific values of Σxi, Σyi, Σ(xi - X), and Σ(xi - X)(yi - α₀ - α₁(xi - X)).

In both cases, finding the exact critical values of the parameters involves solving the equations using linear algebra techniques such as matrix algebra or least squares estimation.

Answer:

100 m

Step-by-step explanation:

Given :

#1) Finding the side length

#2) Calculating perimeter

Answer:

100 m.

Step-by-step explanation:

So the area of a square (or any rectangle) is length (l) x width (w). Additionally, all sides of a square are the same length. So if your area is 625 m sq, then one side length would be the square root of 625, which is 25.

So, as we know that one side length is 25 m, and that the perimeter is all side lengths added together, and that a square has four equal sides,

we can add the four lengths of 25 together: (4)(25) [25+25+25+25].

(4)(25) = 100.

The perimeter of the square is 100 m.
