61 because you always multiply first 60 x 0= 0 so now we have 60+1 which is 61
Answer:By 8(4)P.5, the slope of the line equally inclined to axes is tan(±45
o
)=±1. Hence by P+λQ=0,
5λ+3
2λ+4
=±1
⇒λ=
3
1
,−1. Putting for λ, the two lines are
x−y=0,x+y−2=0.

Answer:
a) Mean = 27.65
Median = 27.645
b) Relative Frequency = 33.33%
Step-by-step explanation:
We are given the following data set:
25.78, 21.06, 36.54, 29.51, 18.96, 34.05
a) Mean and Median
Sorted data: 18.96, 21.06, 25.78, 29.51, 34.05, 36.54
b) BMI above 30 is considered obese
Frequency of obese in the given sample = 2
Relative Frequency =
Answer: The length of AC is 18 ft.
Step-by-step explanation:
By the given diagram,
AM = MB and CN = NB
M and N are the mid points of the sides AB and CB respectively,
Thus, by the mid point theorem,
MN ║ AC,
By the alternative interior angle theorem,
∠BMN ≅ ∠BAC
∠BNM ≅ ∠BCA
Thus, by AA similarity postulate,
ΔBMN ≅ ΔBAC
By the property of similar triangles,
Thus, The length of AC is 18 ft.
