Answer:
first week = m miles
second week = 6 miles less than triple the number of miles they ran the
first week.
Triple of the number of miles they ran the first week = 3 * m = 3m
Therefore = 3m - 6

Answer:
x = 10
Step-by-step explanation:
<u>Complementary angles mean 90 degree angle.</u>
Angle P + Angle Q = 90°
Angle P ---> 29°
Angle Q --> 6x + 1
<u>Find x</u>
Angle P + Angle Q = 90°
29 + 6x + 1 = 90°
30 + 6x = 90
6x = 90-30
6x = 60
x = 60/6
x = 10
Therefore, the value of x = 10.
Angle Q = 6x + 10 --> 6(10) + 1 --> 61°
Answer:
(11.242 ; 12.958)
Step-by-step explanation:
The confidence interval is obtained using the relation :
C. I = xbar ± Zcritical * s/√n
Given that ::
xbar = 12.1 ;
Standard deviation, s = 16.6
n = 1012
C. I = 12.1 ± 1.645 * (16.6/√1012)
C.I = 12.1 ± 0.8583881
C. I = 11.242 ; 12.958
