Answer:
0.66666667
Step-by-step explanation:
A histogram is an image of data that resembles a bar graph and groups several categories into columns along the horizontal x-axis. The numerical count or percentage of occurrences for each column in the data are shown on the vertical y-axis. To see how data distribution patterns look, utilize columns.
(a) Use classes with a 2 minute width and a 14 minute starting point to create a histogram of the journey times. Thus, the first lesson lasts between 14 and 16 minutes.
Describe the distribution's shape. What is the average journey time interval?
If a histogram has a bell shape, its center and spread can be used to parsimoniously characterize it. The axis of symmetry is located at the middle. The spread is the separation between the center and a particular point of inflection. The inflection points of the bell-shaped histogram are indicated here.

Answer: x=-1
Step-by-step explanation:
the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for
you are in luck
x value of the vertex = -4/4 = -1
the line of symmetry is a vertical line, and since it must pass through the vertex
line of symmetry: x=-1
Answer:
Step-by-step explanation:
- Use of low <em>of sines</em>
- <em>Consider triangle CEN</em>
- <em>Bearing of angle counted from zero to the vector of flight</em>
<u>We have </u>
- ∠CNE = complementary with 44° ⇒ m∠CNE = 90° - 44° = 46°
- NE = b = 545 km
- EC = a = 680 km
- ∠ECN = x
<u>Find the measure of angle x:</u>
- sin 46° / a = sin x / b
- sin 46° / 680 = sin x / 545
- sin x = 545 sin 46 deg / 680
- x = arcsin (545 sin 46 deg / 680)
- x = 35° (rounded)
<u>Bearing of the flight from Elgin to Canton is:</u>
- 270° - 35° = 235° as the vector is in the third quadrant
