Answer:
The answer is 774.86
Step-by-step explanation:
Multiply (1.41*106) = 149.46
Multiply (5.9*106)=625.4
Add 149.46+625.4= 774.86

132. The sum of the angles of a six sided polygon is 720° so you can find the missing one from that.
Answer:
Solution given:
the product of (2x– 1) and ( 1/2x -2/3)
- :(2x-1)(½x-⅔)
- 2x(½x-⅔)-1×(½x-⅔)
- x²-4/3 x-½x+⅔
- x²-½x-4/3+⅔
- x²-½x-[4-2]/3
- x²-½x-⅔ is a required answer.
Answer:
The data are at the
<u>Nominal</u> level of measurement.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.
Step-by-step explanation:
The objective here is to Identify the level of measurement of the data, and explain what is wrong with the given calculation.
a)
The data are at the <u> Nominal </u> level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies from 100 basketball, 200 basketball, 300 football, 400 anything else
b) We are being informed that, the average (mean) is calculated for 597 respondents and the result is 256.1.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average (mean).
Let the length equal x
Then the width would be 4x + 8 (8 feet more than 4 times the length)
Area = length x width:
5,472 = x * 4x+ 8
Simplify:
5472 = 4x^2 + 8x
Subtract 5472 from both sides:
4 x^2 + 8x - 5472 = 0
Use the quadratic formula to solve for x.
X = 36
Now you know the length is 36 feet
The width = 4(36) + 8 = 152 feet
Now find the perimeter: 152 + 152 + 36 + 36 = 376 feet.
The answer is B. 376
