Answer:
40 units
Step-by-step explanation:
So first if it was a scale factor of 2.5 you would multiply it by 2.5 for each side. So for the side of 3 you would multiply it by 2.5 which is 7.5 so that side and the other side across from it would be 7.5 units. Then for the next one there is 5 units so you do the same 5x2.5 is equal to 12.5 so will the one below it.
Then it would be (7.5 * 2) + (12.5 * 2)= 15+25+40
So then the perimeter would be 40 units.
Answer:
(12.1409, 14.0591
Step-by-step explanation:
Given that Tensile strength tests were performed on two different grades of aluminum spars used in manufacturing the wing of a commercial transport aircraft. From past experience with the spar manufacturing process and the testing procedure, the standard deviations of tensile strengths are assumed to be known.
Group Group One Group Two
Mean 87.600 74.500
SD 1.000 1.500
SEM 0.316 0.433
N 10 12
The mean of Group One minus Group Two equals 13.100
standard error of difference = 0.556
90% confidence interval of this difference:
t = 23.5520
df = 20

The is it mean, range, mode, or median of the following set of data is 6. 13, 7, 9, 5, 2, 3, 5, 4, 10, 12
grandymaker [24]
the way you have laid this question out is strange but im assuming you want me to find the mean, range, medium and mode of the numbers provided?
<h2>
Answer:</h2>
median=order them and find the middle= <u><em>6</em></u>
mean=add them all up and divide by the amount of numbers=(6+13+7+9+5+3+2+5+4+10+12)/11=<em><u>6.9</u></em>
range= the difference between the smallest and largest number=13-2=<u><em>11</em></u>
mode= the one that appears the most= <em><u>5</u></em>
