This is word for word the problem I am working on in Trig. Its not a Trig question though!

There will be 7 turkeys Xx

This is because:

52 divided by 2 = 26.

26 - 19 = 7.

-Hope this helps! Xx

Answer:

1st, 3rd and 5th statements are true.

Step-by-step explanation:

We have been given a table that hows the number of cars sold each month for 5 months at two dealerships. We are asked to choose the correct statement from the given choices.

1. The mean number of cars sold in a month is the same at both dealerships.

Let us find mean sales for both dealerships.

$\text{Mean}=\frac{\text{Sum of all number of data set}}{\text{Total number in data set}}$

$\text{Mean sales for Admiral autos}=\frac{4+19+15+10+17}{5}$

$\text{Mean sales for Admiral autos}=\frac{65}{5}$

$\text{Mean sales for Admiral autos}=13$

$\text{Mean sales for Countywide Cars}=\frac{9+17+14+10+15}{5}$

$\text{Mean sales for Countywide Cars}=\frac{65}{5}$

$\text{Mean sales for Countywide Cars}=13$

We can see that mean number of cars sold at both dealerships, therefore, statement 1st is true.

2. The median number of cars sold in a month is the same at both dealerships.

Let us arrange our given data set from least to greatest.

Median sales for Admiral autos: 4, 10, 15, 17, 19.

As our data set have 5 data points, therefore, the median will be the value of 3rd data point that is 15.

Median sales for Countywide Cars: 9, 10, 14, 15, 17.

As our data set have 5 data points, therefore, the median will be the value of 3rd data point that is 14.

Since the median number of cars sold at both dealerships is different, therefore, 2nd statement is false.

3. The total number of cars sold is the same at both dealerships.

We have already seen that both dealerships sold 65 cars, therefore, 3rd statement is true.

4. The range of the number of cars sold is the same for both dealerships.

$\text{Range}=\text{The highest value- The Lowest value}$

$\text{Range of Admiral Autos}=19-4$

$\text{Range of Admiral Autos}=15$

$\text{Range of Countywide Cars}=17-9$

$\text{Range of Countywide Cars}=8$

Since the ranges of both dealerships are different, therefore, 4th statement is false.

5. The data for Admiral Autos shows greater variability.

Let us find standard deviation of both data sets.

$\sigma=\sqrt{\frac{\sum(x-\overline x)^2 }{n-1}}$

$\text{SD of Admiral Autos}=\sqrt{\frac{(4-13)^2+(19-13)^2+(15-13)^2+(10-13)^2+(17-13)^2}{5-1}}$

$\text{SD of Admiral Autos}=\sqrt{\frac{(-9)^2+(6)^2+(2)^2+(-3)^2+(4)^2}{4}}$

$\text{SD of Admiral Autos}=\sqrt{\frac{81+36+4+9+16}{4}}$

$\text{SD of Admiral Autos}=\sqrt{\frac{146}{4}}$

$\text{SD of Admiral Autos}=\sqrt{36.5}\approx 6.04$

$\text{SD of Countywide Cars}=\sqrt{\frac{(9-13)^2+(17-13)^2+(14-13)^2+(10-13)^2+(15-13)^2}{5-1}}$

$\text{SD of Countywide Cars}=\sqrt{\frac{(-4)^2+(4)^2+(1)^2+(-3)^2+(2)^2}{4}}$

$\text{SD of Countywide Cars}=\sqrt{\frac{16+16+1+9+4}{4}}$

$\text{SD of Countywide Cars}=\sqrt{\frac{46}{4}}$

$\text{SD of Countywide Cars}=\sqrt{11.5}\approx 3.39$

Since SD for Admiral Autos is 6.04 and SD for Countywide Cars is 3.39, therefore, 5th statement is true indeed.

Forces with magnitudes of 2000 newtons and 900 newtons act on a machine part at angles of +30degrees and -45degrees respectively

mote1985 [20]

To get the resultant magnitude and direction of the forces we need to separate the force into its x and y components. For the x components it is the sum of 2000cos(30) and 900cos(45), which is 2368.4469 N. For the y components it will be the sum of 2000sin(30) and -900sin(45), the value for the second force is negative because it is pointing downwards, their sum would be 363.6038 N. The magnitude for the resultant force can be determined using the pythagorean theorem R=sqrt(2368.4469^2 + 363.6038^2) while its direction is found using tan^-1(363.6038/2368.4469). The final answer would be 2396.1946 N with an angle of 8.7279 degrees from the right side of x axis.
