7.
( \frac{6}{5} ) \: ( -  \frac{10}{9} )
find a common denominator

it will turn into 54 over 45 times -50 over 45

multiply across, leaving the denominator the same

divide the numerator by the denominator

leaving you with 60

ANSWER: 60

8.
- 3 \div  \frac{7}{8}
Turn the whole number into a fraction by multiplying 3 by 8, also write an 8 under your answer, put the negative in front of the fraction

now we have -24 over 8 divided by 7 over 8
divide -24 by 7

now we have -3 over 8

ANSWER=

A population of values has a normal distribution with μ = 155.4 and σ = 49.5 . You intend to draw a random sample of size n = 24
xz_007 [3.2K]

Answer:

(a) The probability that a single randomly selected value lies between 158.6 and 159.2 is 0.004.

(b) The probability that a sample mean is between 158.6 and 159.2 is 0.0411.

Step-by-step explanation:

Let the random variable <em>X</em> follow a Normal distribution with parameters <em>μ</em> = 155.4 and <em>σ</em> = 49.5.

(a)

Compute the probability that a single randomly selected value lies between 158.6 and 159.2 as follows:

P(158.6 < X

*Use a standard normal table.

Thus, the probability that a single randomly selected value lies between 158.6 and 159.2 is 0.004.

(b)

A sample of <em>n</em> = 246 is selected.

Compute the probability that a sample mean is between 158.6 and 159.2 as follows:

P(158.6 < \bar X

*Use a standard normal table.

Thus, the probability that a sample mean is between 158.6 and 159.2 is 0.0411.

Solve 2/3 - 6y = - 1 5/6
alukav5142 [94]

Answer:

<u> y = 19/36</u>

Step-by-step explanation:

Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:

2/3 + 15/6 = 6y

Then you can sum the fractions on the left by using the same denominators:

4/6 + 15/6 = 6y       ==>      19/6 = 6 * y

then  you can pass the 6 that is multiplying on the right to the left - now dividing:

<u> y = 19/36</u>
