What is 3+2? You have to have a good explanation to your answer.​

Answers

Answer:

3+2=5. Lets say you went to Mcdonalds and you wanted to order a 6 piece of nuggets. You place your order and pick it up and drive home. When you get hoome you sit down at a table and unpack your order you find that it does not have 6 pieces but instead has 5. You cant believe it so you go recout. 1, 2, 3, and set them aside only to find 2 left in the box, so the triple check you pull out a calculater and type in 3+2 and you get 5.

Step-by-step explanation:

Find the​ range, variance, and standard deviation for the given sample data. Include appropriate units in the results.Listed below are the measured radiation absorption rates​ (in W/kg) corresponding to various cell phone models. If one of each model is measured for radiation and the results are used to find the measures of​ variation, are the results typical of the population of cell phones that are in​ use?

If one of each model is measured for radiation and the results are used to find the measures of​ variation, are the results typical of the population of cell phones that are in​ use?
A. ​No, because it is necessary to have at least 5 of each cell phone in order to get a meaningful result. Only including one of each cell phone model is not representative of each cell phone model.
B. ​Yes, because the results from any sample of cell phones will be typical of the population.
C. ​Yes, because each model is being represented in the sample. Any sample that considers all possible cell phone models will produce results typical of the population of cell phones.
D. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Answers

Answer:

Range = 1.48-0.63=0.850 W/kg

s= 0.320 W/Kg

s^2 = 0.320^2= 0.103 W^2 /kg^2

D. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Step-by-step explanation:

For this case we have the following data values:

0.95,0.73,0.63,0.91,1.32,1.48,0.63,1.23,0.91,1.41,0.67

The first step on this case is order the datase on increasing way and we got:

0.63 0.63 0.67 0.73 0.91 0.91 0.95 1.23 1.32 1.41 1.48

The range is defined as Range = Max-Min

And if we replace we got:

Range = 1.48-0.63=0.850 W/kg

The sample standard deviation is given by this formula:

s= \sqrt{(\sum_(i=1)^n (X_i -\bar X)^2)/(n-1)}

And if we replace we got s= 0.320 W/Kg

And the sample variance is just the standard deviation squared so we got:

s^2 = 0.320^2= 0.103 W^2 /kg^2

And for the last question about : If one of each model is measured for radiation and the results are used to find the measures of​ variation, are the results typical of the population of cell phones that are in​ use?

We can conclude this:

D. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Determine the number of degrees for the angle in section B of the pie chart . Round to the nearest whole degree Please assist me

Answers

Answer:

115°

Step-by-step explanation:

Measure of the degree of the angle represented by section B on the chart = percentage in the pie chart ÷ 100 × 360. A full circle makes 360°.

Section B represents 32% of the pie chart, therefore, number of degrees for section B = (32)/(100)*360 = (32*360)/(100)

= 115.2

Section B = 115° (to the nearest whole number)

A rectangular garden measures 26ft by 37ft. Surrounding (and bordering) the garden is a path 2ft wide. Find the area of this path. Be sure to include the correct unit in your answer.

Answers

26*37=962sqft
Add 4 ft to both numbers (2ft per side)
30*41=1230sqft
Subtract out the garden area
1230-962=268sqft
The path is 268 sq ft

Does anyone know how to find the measure of this missing angle ?

Answer:

x=57

Step-by-step explanation:

x+28+x+38=180

Step 1: Simplify both sides of the equation.

x+28+x+38=180

(x+x)+(28+38)=180(Combine Like Terms)

2x+66=180

2x+66=180

Step 2: Subtract 66 from both sides.

2x+66−66=180−66

2x=114

Step 3: Divide both sides by 2.

2x/2=114/2

Answer:

x=57

Answer:

57

Step-by-step explanation:

x+28+x+38=180

2x+66=180
