Answer:

1,187

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as;

an = a + (n-1)d

a is the first term

n is the number of terms

d is the common difference

Given the sequence 3, 11, 19, 27...

a = 3

d = 11-3 = 19-11 = 8

n = 149 (since we need the 149th term)

a149 = 3 + (149-1)(8)

a149 = 3+(148)(8)

a149 = 3+1,184

a149 = 1,187

Hence the 149th term is 1,187

Answer:

C

Step-by-step explanation:

7x + 3y = 30 (equation 1)

-2x + 3y = 3 (equation 2)

9x = 27 (subtract the two equations to eliminate y)

x = 3 (divide by 9)

7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)

21 + 3y = 30 (7 * 3 = 21)

3y = 9 (Subtract 21)

y = 3 (divide by 3)

Answer is (3, 3)

Answer:

(3,3)

Step-by-step explanation:

7x + 3y = 30

-2x + 3y= 3

Multiply the second equation by -1 and add together to eliminate y

7x + 3y = 30

2x - 3y= -3

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

9x + 0y = 27

Divide by 9

9x/9 = 27/9

x = 3

Now find y

-2x+3y = 3

-2(3) +3y =3

-6 +3y = 3

Add 6 to each side

3y = 3+6

3y=9

Divide by 3

y = 3

A measure of the probability that the sample's average IQ is below 987 is 44.70 %.

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean.

The Z-standard score's deviation measure, which the p-value is, can be regarded of as a percentile expression. So they do have p-values.

Given: IQ scores are frequently described as having a normal distribution with a mean of 100.0 and a standard deviation of 15.0. A sample of 57 persons is chosen at random.

Z-score = (X- μ)/σ

             = (98-100)/15

             = -0.1333

P value for this z score equals 0.4470 which is 44.70 %

Therefore, the probability that the average IQ of the sample's population is lower than 987 is 44.70 %.

The "b" value is the value immediately to the left of the exponent. (It's not rocket science; it's pattern matching.) Note that the minus sign in g(x) is part of 'a', not part of 'b'.

From the top-down, the functions listed on the left have the b-values shown above.

The angle of depression from the center of the bridge to the platform is approximately 16.94 degrees.

To find the angle of depression, we can use the tangent function. The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

In this case, the opposite side is the height of the platform (297 meters) and the adjacent side is the distance from the platform to the center of the bridge (995 meters).

Using the tangent function, we can calculate the angle of depression as follows:

\[ \tan(\text{{angle}}) = \frac{{\text{{opposite side}}}}{{\text{{adjacent side}}}} \]

Substituting the given values:

\[ \tan(\text{{angle}}) = \frac{{297}}{{995}} \]

To find the angle itself, we can take the inverse tangent (arctan) of both sides:

\[ \text{{angle}} = \arctan\left(\frac{{297}}{{995}}\right) \]

Using a calculator, we can determine that the angle of depression is approximately 16.94 degrees.

The points (x,y) lies in a straight line.

An unending, one-dimensional figure with no breadth is a straight line. It consists of an infinite number of points connected on either side of a point. There is no curvature in a straight line. It might be angled, vertical, or horizontal.

Any angle we draw between any two locations along a straight line will always be a 180-degree angle. A straight line is an infinite-length line that does not have any curves on it. A straight line can be formed between two points also but both ends extend to infinity.

Step-by-step explanation:edge

The footnote in the research paper states that the traditional levels of significance to reject the null hypotheses were relaxed to the 0.10 level because the research was exploratory in nature. This statement suggests that the researchers intentionally chose a higher level of significance in their statistical analysis.

In response to this footnote, you could provide the authors with the following feedback:
1. Acknowledge the exploratory nature of the research: Begin by recognizing that the authors mentioned the exploratory nature of their study in the footnote. This indicates that they were conducting preliminary investigations or searching for patterns and relationships without any preconceived hypotheses.
2. Explain the concept of statistical significance: Provide a brief explanation of statistical significance, which refers to the probability that the observed relationship between variables is not due to chance. Emphasize that traditionally, a significance level of 0.05 is commonly used to determine whether the relationship is statistically significant.
3. Discuss the rationale for relaxing the significance level: Address the authors' decision to relax the significance level to 0.10. Explain that by doing so, they are allowing for a higher chance of finding statistically significant relationships between the predictor and response variables. This decision may be justified in exploratory research, as it allows for a more liberal approach to hypothesis testing.
4. Highlight the implications of relaxed significance levels: Explain that relaxing the significance level increases the likelihood of finding statistically significant results, even if the true relationships are weak or non-existent. This could lead to an increased risk of Type I errors, where a relationship is detected when there isn't one. It is important to note that relaxed significance levels may generate preliminary findings that require further validation.
5. Suggest additional analysis or caution: Finally, recommend that the authors interpret their findings with caution and consider conducting further research to validate their results. Additionally, they may want to include sensitivity analyses to understand the impact of different significance levels on their conclusions. Encourage them to discuss the potential limitations and implications of their decision to relax the significance level in the paper.

Remember to maintain a respectful and informative tone throughout your response. By providing this feedback, you are helping the authors understand the implications of their choice to relax the significance level and encouraging them to critically evaluate their findings.

The shaded area is 34.66 sq. units.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

The shaded area is shown in the graph.

A line y = mx + c

For dashed line, the slope (m) is given by

\(\rm m = \dfrac{y_{2} -y_{1} }{x_{2} -x_{1} } \\\\m = \dfrac{3-0}{1-0} \\\\m = 3\)

And c = 0  because the line is passing through the origin.

so the equation is 3y = x

For x = -1 then y = -1/3

Then

The base and height of the triangle will be 16/3 and 4.

And the height of the trapezium and the sum of the parallel side are 4 and 12.

Then the shaded area will be

\(\rm Shaded\ area\ =\ area\ of\ trapezium\ +\ area\ of\ triangle\\\\Shaded\ area\ = \dfrac{1}{2} (sum\ of\ parallel\ sidess)* height +\dfrac{1}{2} base *height\\\\Shaded\ area\ = \dfrac{1}{2} *12*4 +\dfrac{1}{2} * \dfrac{16}{3} *4\\\\Shaded\ area\ = 34.66\)

\( \frac{ {x}^{2} + 2x - 8 }{ {x}^{2} - 3x - 10 } \)

let the denominator x² - 3x - 10 is f(x),

• Setting this factor equal to 0,

→ x² - 3x - 10 = 0

• By using Middle term splitting method,

→ x² - 5x + 2x - 10 = 0

→ (x² - 5x) + (2x - 10) = 0

• Taking common,

→ x( x - 5 ) + 2( x - 5 ) = 0

→ ( x - 5 ) ( x + 2 ) = 0

• Again, setting these factors equal to 0,

( x - 5 ) = 0 and ( x + 2 ) = 0

→ x = 5 → x = -2

Hence, the values that would make the fraction undefined is x = 5,-2...

The values x = 5 and x = -2 would make the fraction undefined since they would result in a zero denominator.

To find the values that would make the fraction undefined, we need to identify any values of x that would make the denominator equal to zero.

The denominator of the fraction is (\(x^2 - 3x - 10\)). We need to solve the equation:

\(x^2 - 3x - 10 = 0\)

To factorize the quadratic equation, we look for two numbers that multiply to -10 and add up to -3. These numbers are -5 and 2:

(x - 5)(x + 2) = 0

Now, we can set each factor equal to zero and solve for x:

x - 5 = 0 => x = 5

x + 2 = 0 => x = -2

Therefore, the values x = 5 and x = -2 would make the fraction undefined since they would result in a zero denominator.

4,560 pounds of soil

Step-by-step explanation:

Ok, based on the information given we are assuming that Persephone's garden is in the shape of a square or rectangle and the measurements 8 by 19 are in feet. That being the case we first need to calculate the square footage of the garden and we do this by multiplying the length by the width like so...

8 ft * 19 ft = 152 sq. ft.

Now that we know the square footage, we calculate how much soil is needed. Since the question states that she needs 30 pounds of soil per square foot then we multiply the square footage of the garden by 30.

152 sq. ft. * 30lb =  4,560lb

Finally, we can see that Persephone will need 4,560 pounds of soil for her garden.
