Answer:
(7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance.
Step-by-step explanation:
We have a large sample size n = 56 research cotton samples. Besides, and . A 95% large-sample CI for the true average percentage elongation is given by , i.e., or equivalently (7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance because we have a large sample.
8 x - 4 (5 - x) = -44
mutiply the bracket by -4
(-4)(5) = -20
(-4)(-x)= 4x
8x-20+4x= -44
8x+4x-20= -44 ( combine like terms )
12x-20= -44
move -20 to the other side
sign changes from -20 to +20
12x-20+20= -44+20
12x= -44+20
12x= -24
divide both sides by 12
12x/12= -24/12
Answer: x= -2
Answer:
Side = 12 cm, side = 5 cm, side = 8 cm
Step-by-step explanation:
In order to form a triangle with non-zero area, the sum of the shortest two sides must exceed the longest side.
This will be the case for {5, 8, 12}, but not for any of the others.
___
The side lengths {5, 8, 13} will form <em>a triangle with zero area</em>. This is acceptable according to one version of the triangle inequality (a+b≥c) but not according to the other version (a+b>c). Since you are apparently expected to find one "right answer", we assume the answer you want is the one shown above.
Answer:
1) add 5 to each side
2) multiply 8 by 2
Step-by-step explanation:
×/2-5=3
+5 +5
since -5+5 =0 then thats going to go away leaving us with ×/2=3
+5
3+5=8
×/2=8 multiply 2 by 8 since you want to find x
and the answer is ×=16
