Answer:Replacing x with -x will reflect a graph across the y-axis. Multiplying x by 3 before the function is applied will compress the graph horizontally. This means the correct choice is D.

Answer:

(a) The total area of compound figure is [tex]284.52ft^2[/tex].

(b) The total perimeter of compound figure is 68.84 ft.

Step-by-step explanation:

Perimeter: The total distance covered by the figure.

Area: It is defined as the space occupied by the figure.

Given:

Length of rectangular figure = 19 ft

Breadth of rectangular figure = 12 ft

Radius of circle, r = [tex]\frac{12ft}{2} = 6 ft[/tex]

Part (a):

Now calculating the total area of the compound figure.

[tex]\text{Total area}=\text{Area of rectangular figure}+\frac{1}{2}\times \text{Area of circle}\\\\\text{Total area}=\text{Length}\times \text{Breadth}+\frac{1}{2}\times \pi r^2[/tex]

Now putting all the given values in this formula, we get:

[tex]\text{Total area}=(19ft\times 12ft)+\frac{1}{2}\times 3.14\times (6ft)^2\\\\\text{Total area}=284.52ft^2[/tex]

Part (b):

Now calculating the total perimeter of the compound figure.

[tex]\text{Total perimeter}=2\times \text{Length}+Breadth+(\frac{1}{2}\times \text{Circumference})\\\\\text{Total perimeter}=2\times \text{Length}+Breadth+(\frac{1}{2}\times 2\times \pi \times r)[/tex]

Now putting all the given values in this formula, we get:

[tex]\text{Total perimeter}=2\times \text{Length}+Breadth+(\frac{1}{2}\times 2\times \pi \times r)\\\\\text{Total perimeter}=2\times 19ft+12ft+(\frac{1}{2}\times 2\times 3.14 \times 6ft)\\\\\text{Total perimeter}=68.84ft[/tex]

Answer: C

Step-by-step explanation: As the number of trials gets larger the average of the trials approaches the expected value

Answer:

C. As the number of trials gets larger, the average of the trials approaches the expected value.

Step-by-step explanation:

The statement that is true would be that, as the number of trials gets larger, the average of the trials approaches the expected value. A certain random experiment can have a various number of trials, while the expected value is going to be the average of those trials. The more trials that an experiment has, the more data that can be gathered and the average can be better calculated. This average keeps getting closer and closer to the expected value as more trials are completed and the data keeps repeating certain values.

Answer:

68%

Step-by-step explanation:

By the empirical rule, for an approximately normal distribution, about 68% of all values are within one standard deviation from the mean. Refer to the normal distribution bell curve.

The percentage of all values are within 1 standard deviation from the mean is given by A = 68 %

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the centre of the range.

Normal distributions are symmetric, uni-modal, and asymptotic, and the mean, median, and mode are all equal

A data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean

Given data ,

In an approximately normal distribution, about 68% of all values are within 1 standard deviation from the mean

This is known as the empirical rule or the 68-95-99.7 rule, which states that

About 68% of the data falls within one standard deviation of the mean

About 95% of the data falls within two standard deviations of the mean

About 99.7% of the data falls within three standard deviations of the mean

Hence , the data falls within one standard deviation of the mean is 68 %

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I believe that you want to know the number of rides that Katie can take.

Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,

12 + (1.25 × x) = 50

12 + 1.25x = 50

1.25x = 50 - 12

1.25x = 38

x = 38/1.25

x = 30.4

Therefore, Katie can take at most 30 rides.

Given:

The table of data values.

To find:

What is the percentage of 10th grade students are in 2 clubs.

Solution:

From the given table it is clear that the number of 10th grade students are in 2 clubs is 12.

Total number of students in 10th grade is:

[tex]125+12+15=152[/tex]

Now, the percentage of 10th grade students are in 2 clubs is:

[tex]\text{Required percentage}=\dfrac{\text{Number of 10th grade students are in 2 clubs}}{\text{Total number of students in 10th grade}}\times 100[/tex]

[tex]\text{Required percentage}=\dfrac{12}{152}\times 100[/tex]

[tex]\text{Required percentage}=\dfrac{1200}{152}[/tex]

[tex]\text{Required percentage}\approx 7.89\%[/tex]

Therefore, the percentage of 10th grade students are in 2 clubs is 7.89%.
