Answer:
Upper answer is right......
Answer: a=1.16 and b=0.12
Step-by-step explanation:
We know that the residual value= given - predicted
For x=3
The given value =1.1
The residual value=-0.06
Thus
The predicted value (a)= given- residual

For x=4
The given value =3.1
The predicted value = 2.98
Thus
The residual value (b) = given - predicted

.21×54= 11.34
.07×360= 25.2
.4×75= 30
.66×82= 54.12
Hello :
<span>sin 2x = sin x and 0 ≤ x ≤ 2π. .....51°
note : sina = sinb equivaut : (a = b +2k</span>π) or ( a = π - b +2kπ) .... k∈ Z
(1) equiv : ( 2x = x +2kπ) or (2x = π - x +2kπ)
( x = 2kπ) or ( x = π/3 + 2kπ/3)....(general solution )
but : 0 ≤ x ≤ 2π
k = 0 : x = 0 , x = π/3
k= 1 : x = 2π , x = π
k = 2 ; x = 5π/3
Answer:
1260
Step-by-step explanation:
12/72 is 1/6 of the students going to the play
210 students go to play
210 times 6 is 1260
