The scheduled arrival time for a daily flight from Boston to New York is 9:35 am. Historical data show that the arrival time fol

Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

$M = \frac{a+b}{2}$

The standard deviation is:

$S = \sqrt{\frac{(b-a)^{2}}{12}}$

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

$M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5$

Standard deviation:

$S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64$

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Rosa recorded the height (in centimeters) of a pea plant over a 10-day period for a science experiment. Please help me with this

katrin [286]

Answer:

option a)

y = m(0.5) + 1.8

Step-by-step explanation:

Equation

represent the equation of straight line

here m = gradient of straight line

c = y-intercept

First find the gradient of the graph

= 4 - 3 / 4 - 2

= 1 / 2

Put the values in the equation of straight line

y =mx + c

4 = 1/2(4) + c

c = 2

y = 1/2x + 2

which is approximately equal to y = 0.5x + 1.8

A series of transformations maps EFGH onto its image. Determine the series of transformations involving a reflection, translatio

Annette [7]

Answer:

See below

Step-by-step explanation:

Firstly, we'll dilate EFGH by any scale factor.

<u><em>Let's find the scale factor first.</em></u>

=> Scale Factor = $\frac{Side \ of \ dilated \ figure}{Side \ of \ original \ figure}$

=> Scale Factor = $\frac{6}{4}$

=> Scale Factor = 1.5

1) Dilate the figure by a scale factor of 1.5

2) Reflect it across the origin

3) Translate (Move) 5 units down and then 10 units left.

These transformations will map EFGH onto its image.
