Step-by-step explanation:

In any triangle an exterior angle is equal to the sum of the two opposite interior angles.

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

=[tex]\dfrac{5}{12}\text{ ft.}[/tex]               [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

[tex]V=l*w*h[/tex], where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

[tex]V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}[/tex]

Since 1 yard = 3 feet

[tex]1\text{ foot}=\dfrac{1}{3}\text{ yard}[/tex]

[tex]V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}[/tex]

Let the width = X, then the length would be 5x ( 5 times as long as the width).

The perimeter is adding the 4 sides.

x + x + 5x + 5x = 70

Combine the like terms:

12x = 70

Divide both sides by 12:

x = 70/12

x = 5.83

The width = 5.83 cm.

The length = 5 x 5.83 = 29.15

Now round each length to the nearest tenth:

5.8 and 29.2 cm.

The answer is d.

The change in the X values is in multiples of 2.

The change in the h(x) values need to be: -0.3 x 2 = -0.6

Now find the h(x) values that have a difference of -0.6

A negative value is a decrease.

2 to 4 is an increase.

4 to 6 is an increase.

6 to 8 is an increase.

8 to 10 is an increase.

10 to 12 = 20-19.8 = 0.2

12 to 14 = 19.8 - 19.2 = 0.6

The two columns are 12 and 14

Answer:

c

Step-by-step explanation:

C is your answer. Since this is a parallelogram, is means that there are two sets of sides with the same length. Because the measurement of angle K is 82 the angle directly opposite would have the same measurement. That's why angle M is also 82. When you add all the angles of a quadrilateral it adds up to 360 degrees. multiply 82 by 2 to get 164 and subtract that from 360 to get 196. you then have to divide that by 2 and you will get 98 which is the measurement for both angles L and N

Answer:

The correct answer is option C.

m<L = 98°, m<M = 82° and m<N = 98°

Step-by-step explanation:

From the figure we can see a parallelogram KLMN

Properties of parallelogram

1)Opposite sides are equal and parallel.

2) Opposite angles are equal.

3) Adjacent angles are supplementary.

To find the correct option

It is given that, m<K = 82°

By using properties of parallelogram we get

m<L = 98°, m<M = 82° and m<N = 98°

Therefore the correct answer is option C

Answer:

Step-by-step explanation:

The vertex order ABC is clockwise in the original figure and also in the first image: A'B'C'. The altitude from AC to B is up in the original and left in the first image, indicating a rotation 90° CCW.

  The first transformation is a rotation 90° CCW.

The vertex order of A''B''C'' is CCW, indicating a reflection. The direction of the altitude from A''C'' to B'' is still to the left, so the reflection must be over a horizontal line. We find the x-axis bisects the segments A'A'', B'B'', and C'C'', confirming that it is the line of reflection.

  The second transformation is reflection across the x-axis.

Answer:

95%

Step-by-step explanation:

For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level,  wider will be the confidence interval.

This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.

The confidence interval for a population proportion is given by the formula:

[tex]p \pm z\sqrt{\frac{pq}{n} }[/tex]

So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.

Hence 95% confidence interval will be wider than 80% confidence interval.

The 95% confidence interval is wider than the 80% confidence interval because it includes a larger area under the curve of a normal distribution, offering a higher level of confidence the true population parameter falls within this range.

In statistical analysis, especially for polls like the one mentioned about favorite pies, the confidence interval plays a significant role in interpreting the reliability of the results. The 95% confidence interval is wider than the 80% confidence interval. This is because a higher confidence level, in this case 95%, means we are more sure that the actual population parameter lies within the interval, but in order to gain this certainty, the interval necessarily needs to be wider.

This can also be understood in the context of a normal distribution. For a 95% confidence interval, we are including a larger area under the curve of the distribution, thus the interval has to be wider than the one for the 80% confidence interval, which covers a smaller area.

It's important to note, however, that a wider confidence interval doesn't necessarily imply better predictability. It simply means there's a higher level of confidence that the true population parameter falls within the specified range.

Answer:

0.68

Step-by-step explanation:

Given

Mean = μ = 6 cm

SD = σ = 1.5 cm

We have to find the z-scores for 4.5 and 7.5

z-score for 4.5 = z_1 = (x-μ)/σ = (4.5-6)/1.5 = -1.5/1.5 = -1

z-score for 4.5 = z_2 = (x-μ)/σ = (7.5-6)/1.5 = 1.5/1.5 = 1

We have to find area to the left of z-scores

Using the rule of thumb for SD from mean, 68% of data lies between one standard deviation from mean. So the probability of choosing a band with length between 4.5 and 7.5 cm is 0.68 ..

Answer:  ordinal

Step-by-step explanation:

There are 4 levels of measurements scales :-

1. Nominal scale : It is used when we categorize the data on the basis of the characteristic such as Religion, Gender , etc.

2. Ordinal scale : It is used when we can order attributes according to their ranks. For example : First > Second > Third and so on.

3. Interval scale : It provides the characteristic of the difference between any two categories. For example : Fahrenheit scale to measure temperature.

4. Ratio scale : It has all the qualities of nominal, ordinal, and interval measures and in addition a "true zero" point. For example : Age.

From the above definitions , A level of measurement describing a variable whose attributes are rank-ordered and have equal distances between adjacent attributes are ordinal measures.

The correct option is 1.

Step-by-step explanation:

Given information: AD = 25, CD = 5, DB = 1 and CD⊥AB.

According to the Pythagoras theorem,

[tex]hypotenuse^2=base^2+perpendicular^2[/tex]

In triangle BCD,

[tex]CB^2=DB^2+CD^2[/tex]

[tex]CB^2=1^2+5^2[/tex]

  B.  x ≈ 13/8

Step-by-step explanation:

We assume that one iteration consists of determining the midpoint of the interval known to contain the root.

The graph shows the functions intersect between x=1 and x=2, hence our first guess is x = 3/2.

Evaluation of the difference between the left side expression and the right side expression for x = 3/2 shows that difference to be negative, so we can narrow the interval to (3/2, 2). Our 2nd guess is the midpoint of this interval, so is x = 7/4.

Evaluation of the difference between the left side expression and the right side expression for x = 3/4 shows that difference to be positive, so we can narrow the interval to (3/2, 7/4). Our 3rd guess is the midpoint of this interval, so is x = 13/8.

_____

The sign of the difference at this value of x is still negative, so the next guess would be 27/16. It is a little hard to tell what the question means by "3 iterations." Evaluating the function for x=13/8 will be the third evaluation, so the determination that x=27/16 will be the next guess might be considered to be the result of the 3rd iteration.

Answer:

  A.  $14,500

Step-by-step explanation:

The van depreciates ($16000 -1000 = $15000 in 5 years, so $3000 per year. It will be assumed to depreciate half that amount in half a year, so will be worth $1500 less than $16000 at the end of the first calendar year. The book value will be $14,500.

Final answer:

The book value of the minivan at the end of Year 1 is $14,500 after accounting for 6 months of straight-line depreciation of $1,500 from the original cost of $16,000.

Therefore, the correct answer is A. $14,500.

Explanation:

The student's question is related to calculating the book value of a minivan at the end of year 1 using the straight-line depreciation method. To find the book value, we need to first calculate the annual depreciation expense and then subtract it from the original cost of the minivan.

First, we calculate the annual depreciation expense:

Purchase price of minivan: $16,000

Residual value: $1,000

Useful life: 5 years

So, the annual depreciation expense is
(

$16,000

-

$1,000

) /

5 years

= $3,000 per year.

Since the minivan was bought on July 3, we need to account for a partial year of depreciation for year 1. Assuming the end of the year is December 31, that's 6 months (July through December) of depreciation in the first year. Therefore, it would be
$3,000 / 2 = $1,500 for 6 months.

To find the book value at the end of Year 1, we subtract the depreciation for the first 6 months from the purchase price:
$16,000 - $1,500 = $14,500.

Answer:

Nelson burned the most calories per hour

Explanation:

To solve this question, we will get the amount calories burned by each in one hour and then compare the two values

To do this, we will divide the total amount of calories burned by the total time

1- For Sabra:

We are given that she burnt 845 calories in [tex]3\frac{1}{25}[/tex] (which is equivalent to 3.25) hours

Therefore:

Calories burnt in an hour = [tex]\frac{845}{3.25}=260[/tex] calories/hour

2- For Nelson:

We are given that he burnt 1435 calories in [tex]4\frac{7}{8}[/tex] (which is equivalent to 4.875) hours

Therefore:

Calories burnt in an hour = [tex]\frac{1435}{4.875}=294.36[/tex] calories/hour

3- Comparing the two values:

From the above calculations, we can deduce that Nelson burned the most calories per hour

Hope this helps :)

Answer:

Nelson burned more cal/hr than Sabra at a rate of 294.36 cal/hr.

Step-by-step explanation:

To find out how many calories per hour each person burned, divide the amount of calories they burned by the amount of hours they spent exercising.

Sabra: 845 cal / 3.25 hr = 260 cal/hr

Nelson: 1435 cal / 4.875 hr = 294.36 cal/hr

260 < 294.36, so Nelson burned more calories/hour than Sabra.

Step-by-step explanation:

Given

x² + 20x + 100 = 36 ( subtract 36 from both sides )

x² + 20x + 64 = 0 ← in standard form

Consider the factors of the constant term ( + 64) which sum to give the coefficient of the x- term ( + 20)

The factors are + 16 and + 4, since

16 × 4 = + 64 and 16 + 4 = + 20, hence

(x + 16)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 16 = 0 ⇒ x = - 16

x + 4 = 0 ⇒ x = - 4
