Answer:

$10.

Step-by-step explanation:

Let x represent the original cost of bag of cat food.

We have been given that a pet store owner set the price of a bag of cat food at 50% above the cost. So the cost of cat food would be x plus 50% of x.

x+\frac{50}{100}*x\rightarrow x+0.5x=1.5x

We are further told that the price was reduced by 20%, when it did not sell. So price of cat food after reduction would be 1.5x minus 20 percent of 1.5x.

1.5x-(\frac{20}{100}\times 1.5x)

1.5x-(0.20\times 1.5x)

1.5x-(0.3x)

1.2x

Since price after reduction was $12, so we will equate 1.2x with 12 as:

1.2x=12

\frac{1.2x}{1.2}=\frac{12}{1.2}

x=10

Therefore, the original cost of cat food was $10.

Suppose a normally distributed set of stock prices with 3500 observations has a mean of 101 and a standard deviation of 10. Use
KengaRu [80]

Answer:

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 101, Standard deviation = 10

Percentage of of observations in the data set expected to be between the values 91 and 121.

91 = 101 - 10

So 91 is one standard deviation below the mean.

121 = 101 + 2*10

So 121 is two standard deviations above the mean

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.

Of those 50% below the mean, 68% are between one standard deviation below the mean(91) and the mean(101).

Of those 50% above the mean, 95% are between the mean(101) and two standard deviations above the mean(121).

So the percentage of observations in this interval is of:

P = 0.5*0.68 + 0.5*0.95 = 0.815

Number of observations in the interval

81.5% of 3500. So

0.815*3500 = 2853

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

Please help me. I need to turn this 2y=3x+32 into standard form. PLEASE HELP
Artist 52 [7]

Answer:

3x - 2y = -32

Step-by-step explanation:

Ax + By = C

2y = 3x + 32

-3x  -3x

-3x + 2y = 32 (the leading coefficient needs to be positive)

-1(-3x + 2y = 32)

3x - 2y = -32

Hope this helps!
