Madelyn hikes 190.5 meters up a mountain. If she is 62% of the way up, how tall is the mountain?

There are 52 sides in total for a polygon with an interior angle sum of 9000.

We know the sum of the interior angles =  9000°

And let the number of sides  =  n

9000°   =   180°  *  (n - 2)

Divide both sides of the equation by  180°

9000° / 180°   =   n - 2

50   =   n - 2

Add  2  to both sides of the equation.

52   =   n

n   =   52

the number of sides  =  52

If the polygon has an interior  angle sum of 9000 then the total sides it has is 52.

Step-by-step explanation:

A shipping company has 3 different sized cubed boxes.

The volume of the boxes are 216in³,512in³,and 1000in³

We find the height of each volume of box.

a) 216in³,

Volume = h³

Height = cube root (216)

= 6 in

b) 512in³

= Volume = h³

Height = cube root (512)

= 8 in

c) 1000in³

Volume = h³

Height = cube root (1000)

= 10 in

Since: Mia needs to ship a gift with a height of 7 in .

Therefore: the height in inches of the smallest box that Mia can use is 8 inches (8 in)

The claim that there is not much difference between qualitative and quantitative data is incorrect.

Qualitative and quantitative data are two distinct types of data that serve different purposes and have different characteristics.

Qualitative data refers to non-numerical information that is typically obtained through observations, interviews, or surveys. It provides insights into opinions, attitudes, behaviors, and subjective experiences. Qualitative data is often descriptive in nature, expressed in words, narratives, or themes. It allows researchers to explore complex phenomena, understand contextual factors, and capture the richness of human experiences. Examples of qualitative data include interview transcripts, field notes, and open-ended survey responses.

On the other hand, quantitative data is numerical in nature and involves the collection and analysis of measurable variables. It focuses on quantities, statistical analysis, and mathematical modeling. Quantitative data allows researchers to quantify relationships, make predictions, and conduct statistical tests. It is often collected through surveys, experiments, or structured observations. Examples of quantitative data include numerical measurements, survey responses on a Likert scale, and statistical values such as means and standard deviations.

In conclusion, qualitative and quantitative data are distinct in their characteristics, purpose, and analytical approaches. The claim that there is not much difference between them is incorrect.

Inflection points at are x = 0, x = 2, and x = -3.

A more detailed explanation of the answer.

An inflection point occurs when the second derivative changes sign, which means the second derivative is equal to zero. To find the inflection points for the given function, we need to find the x values when f"(x) = 0.

Given f"(x) = x(2 - x)(x + 3)², we set it to 0:

0 = x(2 - x)(x + 3)²

Now, we find the values of x that satisfy the equation:

1) x = 0
2) 2 - x = 0 => x = 2
3) (x + 3)² = 0 => x = -3

So, there are inflection points at x = 0, x = 2, and x = -3. Therefore, the correct answer is E) x = -3 and x = 2.

Answer:

∠3 = 102°

Step-by-step explanation:

║A straight line always equals 180°. So all we need to do is subtract 78° ║from 180° for the missing angle.

180 − 78 = 102

∠3 = 102°

Further explanation:

║The image shows two slanted lines across one vertical line. If we visualize ║a circle around the point where the slanted line intercepts with the vertical ║line, we can solve this.

[we only need one line to work with, because both lines are parallel]

║That circle you visualized divides the intercept into four sectors. One of ║those sectors, or angles, is labled 78°. We need to find the angle measure ║underneath the labled sector. The sector in the bottom right corner has ║the same angle measure as the labled sector, which is 78°. The sector ║labled ∠3 has the same angle measure as the sector in the upper right.

[a full rotation around an angle is always 360°]

║This can be easily solved by subtracting 78° from 180° to get the angle ║measure for the upper right sector, which is equivalent to ∠3. Using basic ║subtraction, 180° − 78° = 102°. We can prove this by multiplying 78° by 2, ║multiplying 102° by two, and adding the products.

78 ⋅ 2 = 156

102 ⋅ 2 = 204

204 + 156 = 360

║Because the sums equal 360°, we can determine the answer is true.

The lower bound of this interval is 51.08, and the upper bound is 58.92.

Given:

Mean = 44

Standard deviation = 9

n = 36

The formula for the confidence interval of the sample mean:

Confidence Interval = \(X \pm z * (\sigma / \sqrt n)\)

For a 95% confidence level, the z-score is approximately 1.96.

Plugging in the values into the formula, we have:

Confidence Interval = 44 ± 1.96 * (9/ √36)

                                 = 44 ± 1.96 * (9/ 6)

                                 = 44 ± 1.96 * 1.5

                                 = 44 ± 2.94

Therefore, the symmetrical interval that includes 95% of the sample means is (46.94, 41.06).

Answer:

\(-4\frac{5}{12}\)

Step-by-step explanation:

Here we have three terms, none with matching denominators.

Now we have to find the least common multiple of 3, 2, and 4. We can ignore the 2 here because the 4 takes care of that. The least common multiple of 3 and 4 is 12. 12 is also divisible by 2, so we've fulfilled those terms.

Now, let's get to work. We have to convert all of those mixed numbers into fractions with a denominator of 12. I'll skip the explanation and just do the work step by step. Ask questions if you are unsure of something.

First, we'll just put them all in a row.

\(-7\frac{2}{3} -5\frac{1}{2} +8\frac{3}{4}\)

Next, I'm going to put them in the forms of improper fractions, just to make this a bit less cluttered.

\(-\frac{23}{3} -\frac{11}{2} +\frac{35}{4}\)

Then, I'll adjust the denominators of the fractions by multiplying the whole fraction by whatever it takes to make that denominator 12. Remember, multiply the numerator and the denominator by the same number.

\(-\frac{23}{3}(\frac{4}{4})-\frac{11}{2}(\frac{6}{6})+\frac{35}{4}(\frac{3}{3})\)

\(-\frac{92}{12} -\frac{66}{12} +\frac{105}{12}\)

Now, let's add them together.

\(-\frac{53}{12}\)

You can leave this as an improper fraction, but I'm going to put this into mixed number form for you.

The required, Mmusi borrowed R3000 from Aggie as per the given conditions.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan.

Amount = Principal [1 + rate×time]

Let's call the amount Mmusi borrowed from Aggie "P".

After two years, he has to pay back
= P + P * 18% * 2
= P + 0.18 * P * 2
= P + 0.36P
= 1.36P

So if he has to pay back R4080, we can set up an equation to solve for P:

1.36P = 4080

To find P, we can divide both sides by 1.36:

P = 4080 / 1.36 = 3000

So Mmusi borrowed R3000 from Aggie.

One advantage of best-guess experiments is that they are often faster and more cost-effective than factorial or design experiments.

Best-guess (trial and error) experiments involve making a hypothesis and testing it through a series of trials until a satisfactory result is achieved. On the other hand, factorial or design experiments involve manipulating multiple variables simultaneously to determine their individual and interactive effects on a response variable.

Both approaches have their advantages and disadvantages depending on the specific research question and goals. They may also be useful in situations where there is limited knowledge about the variables of interest or when the system is too complex to be modeled accurately.

However, best-guess experiments may suffer from issues such as biased or subjective interpretation of results, a lack of control over extraneous variables, and a potential for false positives or negatives.

In contrast, factorial or design experiments provide a more systematic approach to testing hypotheses and offer greater control over variables, leading to more reliable and generalizable results. They may, however, be more time-consuming and expensive to conduct.

Ultimately, the choice between best-guess and factorial or design experiments depends on the research question, available resources, and desired level of precision and control.

The value of x in the pentagon is 35.

We have,

The angles make a straight angle.

So,

x + a = 180

a = 180 - x

And,

2x + b = 180

b = 180 - 2x

And,

91 + c = 180

c = 180 - 91

c = 89

And,

79 + d = 180

d = 180 - 79

d = 101

And,

85 + e = 180

e = 180 - 85

e = 95

Now,

The sum of the interior angles inside a pentagon.

S = (n - 2) × 180 degrees,

n is the number of sides.

So,

S = 540 degrees

Now,

a + b + c + d + e = 540

180 - x + 180 - 2x + 89 + 101 + 95 = 540

-3x + 645 = 540

-3x = 540 - 645

-3x = -105

x = 35
