You can only buy 1 CD using $12 because $12 minus $8 is $4 and $4 is not enough for another CD.

Solve for x: 1/8-2/×=5<br><br>someone pls help me ASAP
cricket20 [7]
Begin by subtracting 1/8 from both sides to get - \frac{2}{x} =5- \frac{1}{8} and get a common denominator of 8 on the right:- \frac{2}{x} = \frac{40}{8} - \frac{1}{8}.  Now simplify and cross-multiply: 39x = -16 andx = -16/39

The mean number of hours that American women who worked outside of the home per week was 34.6 hours with a standard deviation of
sergij07 [2.7K]

Answer:

0.61196

Step-by-step explanation:

When we are given a random number of samples , we solve using the z score formula

z = (x-μ)/σ/√n

where x is the raw score

μ is the population mean = 34.6

σ is the population standard deviation = 13.6

n is the random number of samples = 37

For x = 32

z = 32 - 34.6/13.6/√37

z = -1.16288

Probability value from Z-Table:

P(x = 32) = 0.12244

For x = 36

z = 36 - 34.6/13.6/√37

z = 0.62617

Probability value from Z-Table:

P(x = 36) = 0.7344

The probability their mean hours worked per week is between 32 and 36 hours per week is calculated as:

P(x = 36) - P(x = 32)

= 0.7344 - 0.12244

= 0.61196

Answer:

-$0.16

Step-by-step explanation:

The expected value is the sum of the outcomes multiplied by their probabilities.

E(X) = 1/38 (+68) + 37/38 (-2)

E(X) = -0.16
