How do you find the slope of ordered pairs
DerKrebs [107]

Answer:

the slope is defined as the change in price divided by the change in quantity supplied between two points (i.e. the two ordered pairs). we can use the following formula to calculate it: m = (y2 – y1)/(x2 – x1). in the case of my example, the two ordered pairs are (2, 500) and (1, 250)

Find the product using model or drawing
antiseptic1488 [7]

Fraction multiplication involves multiplying the numerators and the denominators to get the numerator and the denominator of the product respectively

Please find the attached diagrams

1. \dfrac{2}{15}, 2. \dfrac{3}{8}, 3. \dfrac{1}{12}, 4. \dfrac{7}{21}, 5. \dfrac{3}{10}

6. 51, 7. 1, 8. 22, 9. \dfrac{36}{55}, 10. 5\dfrac{1}{3}

Reasons:

The process of multiplication of factors using a model includes;

  • Creating a table that have the number of rows and columns equal to the values in the denominator of the two fractions respectively
  • Shading the number of columns given by the numerator of the fraction that has a denominator equal to the number of columns in the table
  • Shading the number of rows given by the numerator of the  fraction that has a denominator equal to the number of rows in the table
  • Ensuring that the common area are shaded to a different color
  • Simplifying the result

1. \dfrac{2}{3}   \times \dfrac{1}{5} = \dfrac{2}{15}  

2. \dfrac{1}{2}   \times \dfrac{3}{4} = \dfrac{3}{8}

3. \dfrac{1}{4}   \times \dfrac{2}{6} = \dfrac{2}{24} = \dfrac{1}{12}

4. \dfrac{1}{7}   \times \dfrac{2}{3} = \dfrac{7}{21}

5. \dfrac{4}{8}   \times \dfrac{3}{5} = \dfrac{12}{40} = \dfrac{3}{10}

Second part

6. When calculating fractions, 'of' means to 'multiply by', therefore, we have;

\dfrac{17}{25}   \times 75= \dfrac{17}{25}   \times 25 \times 3 = 17 \times 3 =  51

7. \dfrac{7}{6}   \times \dfrac{24}{28} = \dfrac{7}{6}   \times \dfrac{6 \times 4}{7 \times 4} = \dfrac{7}{6}   \times \dfrac{6}{7 }  = 1

8. 12   \times 1\dfrac{5}{6} =6 \times 2   \times \dfrac{11}{6} =2   \times {11} = 22

9. \dfrac{4}{5}   \times \dfrac{9}{11} = \dfrac{4 \times 9}{5 \times 11} = \dfrac{36}{55}

10. 6\dfrac{2}{3}     \times \dfrac{12}{15} =\dfrac{20}{3}  \times \dfrac{12}{15} = \dfrac{4 \times 5}{3}  \times \dfrac{4 \times 3}{5 \times 3} = \dfrac{4}{3}  \times {4} = \dfrac{16}{3} = 5\dfrac{1}{3}

Let x denote the lifetime of a mcchine component with an exponential distribution. The mean time for the component failure is 25
aliina [53]

Answer:

0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

The probability that x is lower or equal to a is given by:

P(X \leq x) = \int\limits^a_0 {f(x)} \, dx

Which has the following solution:

P(X \leq x) = 1 - e^{-\mu x}

The probability of finding a value higher than x is:

P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}

The mean time for the component failure is 2500 hours.

This means that m = \frac{2500}, \mu = \frac{1}{2500} = 0.0004

What is the probability that the lifetime exceeds the mean time by more than 1 standard deviations?

The standard deviation of the exponential distribution is the same as the mean, so this is P(X > 5000).

P(X > x) = e^{-0.0004*5000} = 0.1353

0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations
