Answer:

h(2) = 0

Step-by-step explanation:

Simply plug in 2 in for x in h(x)!

h(2) = -(2) + 2

h(2) = -2 + 2

h(2) = 0

And we have our final answer!

Answer:

H(2) = 0

Step-by-step explanation:

All you need to do is replace x with 2 in the function and solve:

H(2)= -2 + 2

H(2)= 0

The critical value for a left-tailed test of a population standard deviation for a sample of size n=15 is 6.571, 23.685. Therefore, the correct answer is option B.

Critical value is an essential cut-off value that defines the region where the test statistic is unlikely to lie.

Given,

Sample size = n = 15

Level of significance = α=0.05

Here we use Chi-square test. Because the sample size is given for population standard deviation,

For the chi-square test the degrees of freedom = n-1= 15-1=14

The critical values are (6.571, 23.685)...... From the chi-square critical table.

Therefore, the correct answer is option B.

The length of a truck is an example of a continuous data set, and 20 feet is just one possible value within that range.

The given value, "a truck with a length of 20 feet," is an example of a continuous data set.

Continuous data refers to values that can take on any numerical value within a range, with no gaps or interruptions. In this case, the length of a truck can take on any value between 0 and some maximum length, with no gaps or interruptions in between.

In contrast, discrete data refers to values that can only take on certain specific values, usually integers. For example, the number of tires on a truck is a discrete data set because it can only take on integer values (e.g. 4, 6, 8).

Answer:

x = 7 and x = -2

Step-by-step explanation:

To solve the equation 18^(x^2+4x+4) = 18^(9x+18), we can equate the exponents and solve for x.

x^2 + 4x + 4 = 9x + 18

Rearranging the terms:

x^2 + 4x - 9x + 4 - 18 = 0

Simplifying:

x^2 - 5x - 14 = 0

Now we can factor the quadratic equation:

(x - 7)(x + 2) = 0

Setting each factor equal to zero:

x - 7 = 0 or x + 2 = 0

Solving for x:

x = 7 or x = -2

Therefore, the solutions to the equation are x = 7 and x = -2.

Answer:

a. standard deviation

Step-by-step explanation:

Standard deviation measures the variation (how spread out the data is from the mean) of a data set.  

To find the value of x, we calculate the average of the sample observations. Summing up the observations and dividing by the total number of observations, we get:

x = (125 + 122 + 126 + 100 + 155 + 132 + 121 + 118 + 114 + 125 + 142 + 2 + 130 + 110 + 140 + 129 + 3) / 17 = 114.118 seconds (rounded to three decimal places).b) To find the value of R, we calculate the range of each sample by subtracting the minimum observation from the maximum observation. Then we find the average range across all samples:R = (155 - 100 + 142 - 2 + 140 - 110 + 132 - 114 + 142 - 3) / 5 = 109.2 seconds (rounded to three decimal places).

c) The Upper Control Limit (UCL) and Lower Control Limit (LCL) using 3-sigma can be calculated by adding and subtracting three times the standard deviation from the average:UCL = x + (3 * R / d2) = 114.118 + (3 * 109.2 / 1.693) = 348.351 seconds (rounded to three decimal places).LCL = x - (3 * R / d2) = 114.118 - (3 * 109.2 / 1.693) = -120.115 seconds (rounded to three decimal places).

d) The Upper Control Limit Range (UCLR) and Lower Control Limit Range (LCLR) using 3-sigma can be calculated by multiplying the average range by the appropriate factor:UCLR = R * D4 = 109.2 * 2.115 = 231.108 seconds (rounded to three decimal places).LCLR = R * D3 = 109.2 * 0 = 0 seconds.

Follow these procedures to calculate the mean absolute deviation.

1. Determine the data's mean by adding all of the values and dividing by the number of values in the data set.

2. Subtract the mean from each of the data points.

3. Make each difference a good one.

4. Add up all of the positive differences.

5. Subtract this total from the amount of data values in the collection.

This is the  mean absolute deviation.

A data set's average absolute deviation is the sum of its absolute departures from a central point. It is a statistical dispersion or variability summary statistic.

The average distance between the values in a data collection and the set's mean is described by mean absolute deviation. A data collection with a mean average deviation of 3.2, for example, has values that are 3.2 units away from the mean on average.

Step-by-step explanation:

The total number of visitors to the website in the first 8 weeks is 12,750.

To determine the total number of visitors to the website in the first 8 weeks, we can analyze the pattern of doubling the number of visitors each week.

Week 1: 50 visitors

Week 2: 2 * Week 1 = 2 * 50 = 100 visitors

Week 3: 2 * Week 2 = 2 * 100 = 200 visitors

Week 4: 2 * Week 3 = 2 * 200 = 400 visitors

Week 5: 2 * Week 4 = 2 * 400 = 800 visitors

Week 6: 2 * Week 5 = 2 * 800 = 1600 visitors

Week 7: 2 * Week 6 = 2 * 1600 = 3200 visitors

Week 8: 2 * Week 7 = 2 * 3200 = 6400 visitors

By following the pattern, we can see that each week the number of visitors doubles from the previous week.

To find the total number of visitors in the first 8 weeks, we sum up the number of visitors from each week:

Total number of visitors = Week 1 + Week 2 + Week 3 + Week 4 + Week 5 + Week 6 + Week 7 + Week 8

Total number of visitors = 50 + 100 + 200 + 400 + 800 + 1600 + 3200 + 6400

Total number of visitors = 12750

Therefore, the total number of visitors to the website in the first 8 weeks is 12,750.

Answer:

B.   3,158

Step-by-step explanation:

h(x) = -49x − 125

Let x = -67

h(-67) = -49(-67) − 125

          =3283-125

          = 3158

Answer:

Answer B

Step-by-step explanation:

To find the value of h(-67) for the function h(x) = -49x - 125,

we substitute -67 for x in the function and evaluate it.

h ( - 67 ) = - 49 ( - 67 ) - 125

Now we can simplify the expression:

h ( -67 ) = 3283 - 125

h ( -67 ) = 3158

To find the solution of the compound inequality x − 2 > 4 or 5x ≥ 35, we need to solve each inequality separately and then combine their solutions using the OR operator.

Solving x − 2 > 4, we add 2 to both sides to get x > 6.
Solving 5x ≥ 35, we divide both sides by 5 to get x ≥ 7.

The solution of the compound inequality x − 2 > 4 or 5x ≥ 35 is the set of all values of x that satisfy at least one of the inequalities, which is x > 6 or x ≥ 7.

To graph this solution, we draw a number line and mark the points 6 and 7 with open circles (because they are not included in the solution). Then we shade the region to the right of 6 and/or to the right of 7, as shown below:

<---o---o=========>

The open circles indicate that 6 and 7 are not included in the solution, because x can be any value greater than 6 or any value greater than or equal to 7, but not both at the same time.

the problem is x > 6 or x ≥ 7. To explain this solution, we need to solve each inequality separately and then combine the results.

First, we solve x − 2 > 4 by adding 2 to both sides to get x > 6.

Next, we solve 5x ≥ 35 by dividing both sides by 5 to get x ≥ 7.

To combine the results, we take the union of the two solutions, which gives us x > 6 or x ≥ 7. This means that any value of x that is greater than 6 or equal to 7 will satisfy the original compound inequality.

The graph that represents this solution is a number line with an open circle at 6 and a closed circle at 7, shading everything to the right of 6 and including 7.

Removing the electric car from the data set will reduce the standard deviation as the extreme value of 112 mpg is taken out, resulting in a decrease in the spread of the data. The interquartile range (IQR) will also be affected as the extreme outlier is taken out, will decrease the spread of the data in the boxplot.

The electric car with a rating equivalent to 112 miles per gallon is an extreme outlier, which means it is very far from the rest of the data. Therefore, removing this outlier from the data set will decrease the variability and, consequently, decrease the standard deviation. The extreme outlier with the rating equivalent to 112 miles per gallon is outside of the whiskers of the boxplot, which means it is beyond the range of the middle 50% of the data. Therefore, removing this outlier from the data set will decrease the spread of the data in the boxplot and, consequently, decrease the IQR.
