A square field has 3,844 sq. meters of land. What is the width of the field?

Answer:

Is 03.841

Step-by-step explanation:

To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.

In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.

To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.

The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.

Therefore, the correct answer is 03.841.

Answer:

g = 12

Step-by-step explanation:

First, simplify by subtracting 4 from 7:

g + 7 - 4 = 15

g + 3 = 15

Solve for g by subtracting 3 from both sides:

g = 12

So, the answer is g = 12

Simplify by subtracting 4 from 7:

g + 7 - 4 = 15

g + 3 = 15

Solve for g by subtracting 3 from both sides:

g = 12

 answer is g = 12

Step-by-step explanation:

Answer:

I would say stratified sample or cluser sampling.

Step-by-step explanation:

The correct answer is:

a = 43%

b = 88%

To determine the values of a and b in the relative frequency table, we need to analyze the information provided in the Venn diagram and the given table.

From the Venn diagram, we can gather the following information:

The circle labeled "satellite" has a value of 55.

The circle labeled "cable" has a value of 75.

The overlap between the two circles is labeled as 12.

Using this information, we can complete the table:

First column - "Satellite":

Entries: Satellite, Not satellite, Total

Total: 55 (as given in the Venn diagram)

Second column - "Cable":

Entries: Blank, 51%, Blank

To find the value for the "Cable" entry, we need to subtract the overlap (12) from the total number of cable users (75).

Cable: 75 - 12 = 63

Therefore, the entry becomes: Blank, 51%, Blank

Third column - "Not Cable":

Entries: a, b, Blank

To find the value for "a," we subtract the overlap (12) from the total number of satellite users (55).

a: 55 - 12 = 43

To find the value for "b," we subtract the overlap (12) from the total number of households (100).

b: 100 - 12 = 88

Therefore, the entries become: 43, 88, Blank

Fourth column - "Total":

Entries: Blank, Blank, 100%

The total number of households is given as 100% (as stated in the question).

Therefore, the values of a and b in the relative frequency table are:

a = 43% (rounded to the nearest percent)

b = 88% (rounded to the nearest percent)

Hence, the correct answer is:

a = 43%

b = 88%

There are countless possibilities for shapes that are similar but not congruent to shape 1, as long as they maintain the same proportions and shape.

There are many shapes that are similar but not congruent to shape 1. Similar shapes have the same shape, but their sizes may be different. In contrast, congruent shapes have the same shape and size.

One example of a similar shape to shape 1 is a rectangle that is twice as long and half as wide. Another example could be a square that is three times larger in area than shape 1.

A parallelogram that has the same base as shape 1 but is three times as tall is also similar but not congruent.

Step-by-step explanation:

B^2+8b+7 is a quadratic expression. It can be factored as (b+7)(b+1).

To factor a quadratic expression, you can use the following steps:

1. Find two numbers that add up to the coefficient of the middle term (8) and multiply to the constant term (7).

2. Write the quadratic expression as a product of two binomials, with the two numbers you found in step 1 as the coefficients of the terms in each binomial.

In this case, the two numbers that add up to 8 and multiply to 7 are 7 and 1. So, we can factor B^2+8b+7 as follows:

(b+7)(b+1)

This means that B^2+8b+7 is equal to the product of (b+7) and (b+1).

Here is a step-by-step explanation of how to factor B^2+8b+7:

1. The coefficient of the middle term is 8.

2. The constant term is 7.

3. The two numbers that add up to 8 and multiply to 7 are 7 and 1.

4. Therefore, B^2+8b+7 can be factored as (b+7)(b+1).

Answer:

Step-by-step explanation:

From the information given:

Mean \(\overline x = \dfrac{\sum x_i}{n}\)

Mean \(\overline x = \dfrac{69+103+126+122+60+64}{6}\)

Mean \(\overline x = \dfrac{544}{6}\)

Mean \(\overline x = 90.67\) pounds

Standard deviation \(s = \sqrt{\dfrac {\sum (x_i - \overline x) ^2}{n-1}\)

Standard deviation \(s = \sqrt{\dfrac {(69 - 90.67)^2+(103 - 90.67)^2+ (126- 90.67) ^2+ ..+ (64 - 90.67)^2}{6-1}}\)

Standard deviation s = 30.011 pounds

B) Find a 75% confidence interval for the population average weight of all adult mountain lions in the specified region.

At 75% confidence interval ; the level of significance ∝ = 1 - 0.75 = 0.25

\(t_{(\alpha/2)}\) = 0.25/2

\(t_{(\alpha/2)}\) = 0.125

t(0.125,5)=1.30

Degree of freedom = n - 1

Degree of freedom = 6 - 1

Degree of freedom = 5

Confidence interval  = \((\overline x - t_{(\alpha/2)(n-1)}(\dfrac{s}{\sqrt{n}})< \mu < (\overline x + t_{(\alpha/2)(n-1)}(\dfrac{s}{\sqrt{n}})\)

Confidence interval  = \((90.67 - 1.30(\dfrac{30.011}{\sqrt{6}})< \mu < (90.67+ 1.30(\dfrac{30.011}{\sqrt{6}})\)

Confidence interval  = \((90.67 - 1.30(12.252})< \mu < (90.67+ 1.30(12.252})\)

Confidence interval  = \((90.67 - 15.9276 < \mu < (90.67+ 15.9276)\)

Confidence interval  =  \((74.7424 < \mu <106.5976)\)

i.e the lower limit = 74.74 pounds

    the upper limit = 106.60 pounds

An equation for the total cars and trucks for dealership A is: x + y = 164.

An equation for the total cars and trucks for dealership B is: 2x + 0.5y = 229.

The number of cars that dealership A sold is: 98 cars.

The number of trucks that dealership B sold is: 66 trucks.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of cars sold and number of trucks sold, and then translate the word problem into an algebraic equation as follows:

Since the first dealership sold a total of 164 cars and trucks, a linear equation to model this situation is given by;

x + y = 164.

Additionally, the second dealership sold twice as many cars and half as many trucks as the first dealership, with a total of 229 cars and trucks;

2x + 0.5y = 229.

By solving the systems of linear equations simultaneously, we have:

2x + 0.5(164 - x) = 229

1.5x + 82 = 229

x = 98 cars.

For the y-value, we have;

2(98) + 0.5y = 229

0.5y = 229 - 196

y = 33/0.5

y = 66 trucks.

Step-by-step explanation:

If your recursive definition is ...

  \(\begin{cases}a_1=4\\a_{n}=34a_{n-1}\end{cases}\)

this defines a geometric sequence with a first term a1 = 4 and a common ratio of r = 34. The general form of the explicit function is ...

Answer:

Change in net operating income = $4,950

Step-by-step explanation:

Missing Detail;

Contribution margin = $105 per unit

Current selling unit = 5,300

Increase in monthly sale = 190 unit

Advertisement cost = $15,000

Find:

Change in net operating income

Computation:

Change in net operating income = [Contribution margin x Increase in monthly sale] - Advertisement cost

Change in net operating income = [105 x 190] - 15,000

Change in net operating income = [19,950] - 15,000

Change in net operating income = $4,950

Answer:

44 because 22 multiplied by 2 is 44

Answer:

22

Step-by-step explanation:

Let's assume Raj's current age is R.

According to the given information, Nora is twice as old as Raj, so her current age is 2R.

Nora is also half as old as Ethan, which means Ethan's current age is 2 * 2R = 4R.

In 22 years, Ethan will be twice as old as Raj, so we can set up the equation:

4R + 22 = 2(R + 22)

Let's solve this equation to find the value of R:

4R + 22 = 2R + 44

4R - 2R = 44 - 22

2R = 22

R = 11

Now that we know Raj's current age is 11, we can find Nora's age:

Nora's current age = 2R = 2 * 11 = 22

Therefore, Nora's present age is 22 years.
