Find the value of x in the triangle above

Answers

Answer 1

Answer:

Answer: x = 8

Step-by-step explanation: So you have 3 sides and 3 numbers. Identify the side that has a number without a variable. (This goes for both triangles) Then you divide the 1st number by the 2nd. In this case it would be 20 or side "B" divided by 5 or side "E", which equals 4. You then take 4 and multiply it by 4 or side "D" (Because it's the only other side that does not have a variable) and you take your answer (16) and 2x or side "A", and make an equation. The equation would be : 2 * x = 16. Now solve the equation. Your answer is : x = 8.

Complete the chart to find the mean,variance,and standard deviation. 45 340 400 825

Answers

Answer:

A. Mean = 402.5

B. Variance = 77,556.25

C. Standard Deviation = 278.49

Step-by-step explanation:

Let's calculate the mean, variance and standard deviation of the set of numbers given:

A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 = 402.5

B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =77,556.25

C. Standard Deviation = √Variance = √77,556.25 = 278.49

Answer:

1. 45⠀= -357.5⠀= 127,806.3⠀mean = 402.5

2. 340⠀= -62.5⠀ = 3,906.3⠀variance = 77,556.3

3. 400⠀= -2.5⠀= 6.3⠀deviation = 278.5

4. 825⠀= 422.5⠀= 178, 506⠀n = 4

Σ X = 1,610⠀X = 402.5⠀Σ (X - X)2 = 310,225.2

terrance must decide which job offer to accept. one job pays $25 per hour for 37 1/2 hours each week and the other pays $825 per week regardless of how many hours he works. which job should terrance take? why?

If the first job pays $25 per hour for 37 1/2 hours each week .. You have to multiply $25 & 37 then divide by 2. Then you will see that you get $462.5 each week . So Terrance would choose the second job because he would get paid more .
