Answer:

c > 7

Step-by-step explanation:

Now we have to,

→ Find the required value of c.

The equation is,

→ 2(3c + 15) + 4c > 100

Then the value of c will be,

→ 2(3c + 15) + 4c > 100

Applying Distributive property:

→ 2(3c) + 2(15) + 4c > 100

→ 6c + 30 + 4c > 100

Combining the like terms:

→ 10c + 30 > 100

→ 10c > 100 - 30

→ 10c > 70

Dividing the value 70 with 10:

→ c > 70 ÷ 10

→ [ c > 7 ]

Hence, the answer is c > 7.

Hello !

Answer:

[tex]\boxed{\sf c > 7 \ \ \ ||\ \ \ \sf (7,+\infty)}[/tex]

Step-by-step explanation:

We are looking for the values of c that satisfy the following inequality :

[tex]\sf 2(3c + 15) + 4c > 100[/tex]

Let's expand the left side of the inequality.

[tex]\sf 2\times 3c +2\times 15+4c > 100\\6c+30+4c > 100[/tex]

Now we will combine like terms :

[tex]\sf 10c+30 > 100[/tex]

Let's substract 30 from both sides of the inequality.

[tex]\sf 10c+30-30 > 100-30\\10c > 70[/tex]

Finally, let's divide both sides by 10.

10>0 so the inequality remains the same.

[tex]\sf\frac{10c}{10} > \frac{70}{10} \\\boxed{\sf c > 7}[/tex]

This sample is likely to be biased because it only includes individuals who use the city's parks, which means it may not represent the entire population of voters who would be affected by a tax increase to improve the parks.

A sample is a subset or a smaller group of individuals or 17 that are selected from a larger population to represent the population.

The park commission's study of 500 park users is likely biassed because it only covers people who use the city's parks. This indicates that the sample does not accurately reflect the full electorate who would be impacted by a tax hike to fund park improvements.

Various people may hold various views regarding whether or not a tax increase is required to develop the parks. For instance, if they don't frequent the parks or have other priorities for their tax money, they might be less likely to approve a tax hike.

If the park commission only conducted surveys of people at specific times of day or in specific locations of the city, the sample may also be skewed. This could omit those who visit the parks at various hours or in various locations around the city.

In order to get accurate and valid results, it's crucial to utilise a representative sample that includes people from different demographic groups. A biased sample can produce results that are erroneous or misleading.

The time series component that reflects the random changes in a time series that are not caused by any other components, and tends to hide the existence of the more predictable components, is called the "random" or "irregular" component.

It represents the noise or fluctuations in the time series that cannot be explained by any of the other components, such as trend, seasonality, or cyclical variations. The irregular component is also known as the "white noise" or "error" component, and it is typically modeled as a random process with zero mean and constant variance. It is important to separate out the irregular component from the other components in order to identify the underlying patterns and trends in the time series, and to make accurate forecasts and predictions.

The best type of study is RCT randomized controlled trial.

The practise of gathering and analysing data with the purpose of identifying patterns and trends is known as statistical analysis. It is a technique for eliminating bias from data evaluation by using numerical analysis. This method is beneficial for gathering research interpretations, creating statistical models, and organising surveys and studies.

In the false idea that there must be an underlying causal relationship because the data reveals a correlation, people frequently misunderstand and misuse the concept of causality in statistics. The best method for proving that two variables are causally related is to utillize a controlled study.

Randomised controlled trials (RCTs) are the most effective study design for proving causality. The treatment group in an RCT receives the intervention under study, whilst the control group either receives no intervention or a placebo. Participants are then randomly assigned to one of the two groups. The RCT helps to adjust for confounding variables and demonstrate a cause-and-effect relationship between the intervention and the result by randomly allocating participants.

The measure of angle Y is m - 8 = 72.25 - 8 = 64.25 degrees.

What is the supplementary angle?

Two angles are said to be supplementary if their sum is equal to 180 degrees. In other words, if angle A and angle B are supplementary, then:

A + B = 180.

Since angles X and Y are supplementary, their measures add up to 180 degrees. So we have:

X + Y = 180

Substituting the given values, we get:

115.75 + (m - 8) = 180

Simplifying, we get:

m - 8 = 180 - 115.75

m - 8 = 64.25

The 95% confidence interval for the population proportion of student loan borrowers with loans totaling more than $20,000 is approximately (0.3235, 0.3765).

To construct a 95% confidence interval for the population proportion of student loan borrowers with loans totaling more than $20,000, we need to calculate the sample proportion, standard error, and critical value.

1. Sample proportion (p) = Number of students with loans over $20,000 / Total sample size
p = 448 / 1280 ≈ 0.35

2. Standard error (SE) = √(p * (1 - p) / n)
SE ≈ √(0.35 * (1 - 0.35) / 1280) ≈ 0.0135

3. For a 95% confidence interval, we use a critical value (z) of 1.96.
Margin of error (ME) = z * SE
ME ≈ 1.96 * 0.0135 ≈ 0.0265

4. Calculate the confidence interval:
Lower limit = p - ME ≈ 0.35 - 0.0265 ≈ 0.3235
Upper limit = p + ME ≈ 0.35 + 0.0265 ≈ 0.3765

The relative frequency of students that are of the 1 to 5 class and are left-handed is 40%.

Relative frequency is the ratio of the number of times an event occurs to the number of trials. This can be expressed as a fraction, a percentage, or a proportion.

This can be calculated using the following equation:

Relative Frequency = (Number of Left-Handed Students in 1 to 5 Class / Total Number of Students in 1 to 5 Class) x 100

Relative Frequency = (17 / (17 + 25)) x 100

Relative Frequency = 40%

This calculation shows that 40% of students in the 1 to 5 class are left-handed. This percentage can be rounded to the nearest whole percentage, giving the answer of 40%.

By comparing the relative frequency of left-handed students in the 1 to 5 class to the relative frequency in the other classes, it can be seen that the 1 to 5 class has the highest relative frequency of left-handed students.

This could be due to the developmental stage of students in this age group, as studies have shown that being left-handed is more common in children aged 5 to 10 than in adults.

Alternatively, it could be due to cultural factors, such as left-handed students feeling more comfortable in the 1 to 5 class due to the younger age group.

The solution in natural numbers for the equation is x = 100 and y = 1.

The positive integers 1, 2, 3, 4, 5,... are known as "natural numbers." N stands for the set of natural numbers. Natural numbers are the building blocks of mathematical operations including addition, subtraction, multiplication, and division. They are also used to count objects. They make up a portion of the set of whole numbers, which also contains the natural numbers and 0 as well. There is no biggest natural number since the collection of natural numbers is endless and unbounded.

To determine the solution of the equation we use the difference of square identity given as:

(x + y)(x - y).

Now, for the given function we have:

(x - y)(x + y = 303

The two factors of 303 are 101 and 99.

Thus,

x + y = 101

x - y = 99

Adding the two equations we have:

2x = 200

x = 100

Now, for x = 100 the value of y is:

100 - y = 99

y = 1

Hence, the solution in natural numbers is x = 100 and y = 1.

Answer:

[tex]-13 > -21[/tex]

-13 is the warmer temperature.

Step-by-step explanation:

When comparing negative numbers, the number closer to zero on the number line is greater.

(OR, the negative number that, if it was positive, would be less).

In this case, that number is -13.

We now know that -13 is greater than -21, so we can write this inequality:

[tex]-13 > -21[/tex]

In regards to temperature, greater numbers usually mean hotter temperature, so -13 is the warmer temperature.

SA = 2lw + 2lh + 2wh = 42 m^2 ... (1)

And the volume of the original prism is given by:

V = lwh = 18 m^3 ... (2)

If you enlarge the dimensions of the prism by a factor of 4, then the new dimensions will be 4l, 4w, and 4h. The new surface area of the prism will be:

New SA = 2(4l)(4w) + 2(4l)(4h) + 2(4w)(4h)

= 32lw + 32lh + 32wh

= 32(2lw + 2lh + 2wh)

= 32(42)

= 1344 m^2

So, the surface area of the enlarged prism is 1344 m^2.

Similarly, the new volume of the prism will be:

New V = (4l)(4w)(4h)

= 64lwh

= 64(18)

= 1152 m^3

So, the volume of the enlarged prism is 1152 m^3.

Therefore, the surface area of the prism is 1344 m^2 and the volume of the prism is 1152 m^3 after the dimensions are enlarged by a factor of 4.

The coordinates of P that partitions AB in the ratio 1 to 3 include the following: [4, -4].

In this scenario, line ratio would be used to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 1 to 3.

In Mathematics and Geometry, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical equation:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

By substituting the given parameters into the formula for line ratio, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(1(6) + 3(2))/(1 + 3)],  [(1(6) + 3(-6))/(1 + 3)]

The measure of the angle in degrees is approximately 713 degrees. Note that this result is greater than 360 degrees because the angle is not a standard angle in a plane but a measure in three-dimensional space.

Since 1/360th of the circumference of the circle is 0.5 cm long, the circumference of the circle is 360 times longer, or 180 cm long.

The arc subtended by the angle is 79 cm long, which is a fraction of the entire circumference. To find the angle in degrees, we need to convert the arc length to an angle measure using the formula:

angle measure = (arc length / circumference) x 360 degrees

Substituting the values we know, we get:

angle measure = (79 cm / 180 cm) x 360 degrees

Simplifying the fraction, we get:

angle measure = 1.9833 x 360 degrees

Rounding to the nearest degree, we get:

angle measure ≈ 713 degrees
