answer:

mean: 15.8

median: 12

mode: no mode

range: 27

step-by-step explanation:

  • first know how to find each of the above and what they are
  • mean = (avg) add all the numbers, then divide by the number of numbers
  • median = the middle number from increasing order
  • mode = the one that repeats the most
  • range = the difference between the largest and smallest number

8, 35, 10, 12, 14

<u>mean</u>

8 + 35 + 10 + 12 + 14 = 79

  • there are five numbers

79 / 5 = 15.8

<u>median</u>

  • put them from smallest to largest

8, 10, 12, 14, 35

  • 12 is the median OR the middle number

<u>mode</u>

  • no number repeat, so no mode

<u>range</u>

35 - 8 = 27

A culture of the bacterium Salmonella enteritidis initially contains 50 cells. When introduced into a nutrient broth, the cultur
photoshop1234 [79]

Answer:

The expression for the number of bacteria after t hours is P(t) = 50e^{0.2922t}

Step-by-step explanation:

When introduced into a nutrient broth, the culture grows at a rate proportional to its size.

This means that the size of the population, after t hours, is modeled by the following differential equation:

\frac{dP}{dt} = rP

In which R is the growth rate.

The solution of this differential equation is:

P(t) = P(0)e^{rt}

In which P(0) is the initial population.

A culture of the bacterium Salmonella enteritidis initially contains 50 cells.

This means that P(0) = 50, and so:

P(t) = P(0)e^{rt}

P(t) = 50e^{rt}

After 1.5 hours, the population has increased to 775.

This means that P(1.5) = 775. We use this to find r. So

P(t) = P(0)e^{rt}

500e^{1.5r} = 775

e^{1.5r} = \frac{775}{500}

\ln{e^{1.5r}} = \ln{\frac{775}{500}}

1.5r = \ln{\frac{775}{500}}

r = \frac{\ln{\frac{775}{500}}}{1.5}

r = 0.2922

The expression is:

P(t) = 50e^{rt}

P(t) = 50e^{0.2922t}

The expression for the number of bacteria after t hours is P(t) = 50e^{0.2922t}

(a) Write down the gradient of the line with equation y = 7 - 4x The line L passes through the points with coordinates (- 3, 1)
lesya [120]

Note: Let us consider, we need to find the gradient of line L.

Given:

The given equation of a line is:

y=7-4x

The line L passes through the points with coordinates (- 3, 1) and (2, - 2).

To find:

The gradient of the given line and the gradient of line L.

Solution:

Slope intercept form of a line is:

y=mx+b                ...(i)

We have,

y=7-4x                   ...(ii)

On comparing (i) and (ii), we get

m=-4

Therefore, the gradient of the given line is -4.

The line L passes through the points with coordinates (- 3, 1) and (2, - 2). So, the gradient of line L is:

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{-2-1}{2-(-3)}

m=\dfrac{-3}{2+3}

m=\dfrac{-3}{5}

Therefore, the gradient of the line L is \dfrac{-3}{5}.
