Answer:
7x-14=2x+11
Step-by-step explanation:
Collect like terms
7x-2x=11+14
5x=25
Divide both sides by the coefficient of x(5).
x=25/5
x=5
Answer:
She must work at least 7 hours. All possible values are 7, 8, 9, 10
Step-by-step explanation:
14 - 4 = 10
4($7)=$28
$130-$28=$102
$102÷$15=6.8
$15x7=$105
$105+$28=$133
$15x8=$120
$120+$28=$148
$15x9=$135
$135+$28=$163
$15x10=$150
$150+$28=$178

Step-by-step explanation:
(a)
The median is represented by the solid vertical line inside the box, that is
median = 58
(b)
The interquartile range is the difference between the upper and lower quartiles.
The upper quartile is the value on the right side of the box, that is 72
The lower quartile is the value on the left side of the box, that is 34
Interquartile range = 72 - 34 = 38
(c)
The range is the difference between the maximum and minimum values
The maximum is indicated by the vertical bar on the right outside the box
The minimum is indicated by the vertical bar on the left outside the box
Range = 86 - 10 = 76
Answer:
5 units
Step-by-step explanation:
Given:-
- The two points C and D are given:
C ( -6 , 5 ) & D ( -3 , 1 )
Find:-
The distance between the two points
Solution:-
- The distance (d) between two arbitrary points ( x1 , y1 ) & ( x2, y2 ) in a cartesian coordinate system is given by the following formula:
Where,
C = ( -6 , 5 ) = ( x1 , y1 )
D = ( -3 , 1 ) = ( x2 , y2 )
- Then we can calculate the distance d between the two given points:
- The distance between the given points C and D is d = 5 units
