I think the answer is 325
The correct proportion can be written in two ways:
one way . . . . . $10.30/10 = x/2
other way . . . . 10/$10.30 = 2/x
(Of course, the left side and right side can be swapped too.)
Neither of these equations appears on the list, so
the correct choice appears to be "none of the above". (e)
Answer: 9
Step-by-step explanation:
Evaluate=
(256 x 3^-5 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 1)^-2 x (3^2/2^3)^4 x 2^28
Multiply=
(256/243)^-2 x (3^2/2^3)^4 x 2^28
Evaluate=
59049/65536 (3^2/2^3)^4 x 2^28
59049/65536 (1/9/2^3)^4 x 2^28
59049/65536 (1/9/8)^4 x 2^28
Divide=
59049/65536 (1/72)^4 x 2^28
Evaluate=
59049/65536 x 1/26873856 x 2^28
59049/65536 x 1/26873856 x 268435456
Multiply=
9
A) The empirical rule tells you the probability of being within 1 standard deviation of the mean is 68%.
b) The probability that the sample mean falls within 3 standard deviations* of the mean is 99.7%.
___
* The standard deviation of the sample mean is 1/√9 = 1/3 of the standard deviation of an individual sample. Hence the same limits (90-110) now cover 3 standard deviations of the sample mean.
Answer:
15
Step-by-step explanation:
The sides add to 63, so:
