Answer:
1
Step-by-step explanation:
To get the box plot we begin by arranging the data in ascending order:
<span>135, 149, 156, 112, 134, 141, 154, 116, 134, 156
rearranging we get:
112,116, 134, 134, 135, 141, 149, 154, 156, 156
then:
Lower value=112
Q1=134
Median=(135+141)/2=138
Q3=154
Largest value=156
The second figure is the correct figure.

Answer:
<h2>
h(x) = 0.0065x+1.25</h2>
Step-by-step explanation:
Given the time length in hours of a certain airplane flight represented by the function f(x) = 0.0025x + 0.75.
The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5.
x is the number of miles for the flight
The function that represents the sum of the flight time lengths is given as h(x) as shown;
h(x) = f(x) + g(x)
To get h(x), we will substitute the functions f(x) and g(x) into formula for function h(x) as shown below;
h(x) = (0.0025x + 0.75)+(0.004x + 0.5)
Collecting the like terms;
h(x)= 0.0025x + 0.004x + 0.75 + 0.5
h(x) = 0.0065x+1.25
This gives the sum of the flight time lengths
3x² + 2x - 4 = 0
Δ = b² - 4.a.c
Δ = 2² - 4 . 3 . -4
Δ = 4 - 4. 3 . -4
Δ = 52
x = (-b +- √Δ)/2a
x' = (-2 + √52)/2.3
x'' = (-2 - √52)/2.3
x' = 0,8685170918213297
x'' = -1,5351837584879966
2 Decimal places
x' = 0,87
x'' = -1,54
