1.A school assembly has 179 students in it. Nine teachers escort "k" number of
students out of the assembly, until there are 26 students remaining.
2. a i guess
y<2x+2
2 is your y intercept and your slope is 2 (positive)
no or equal to so we have a positive slanted dotted line
your answer is the last one

Answer:
389 feets apart
Step-by-step explanation:
Given that:
Building A
Height = 400feets
Angle of elevation = 70°
Building B:
Height = 300 feets
Angle of elevation = 52°
Distance from the foot of building A to where Jonny is standing = x (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 70 = 400/ x
2.7474774x = 400
x = 145.58809 feets
Distance from the foot of building B to where Jonny is standing = y (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 52 = 300/ y
1.2799416y = 300
y = 145.59
y = 234.38568 feets
x + y = distance between the two buildings
(145.58809 + 234.38568) feets
= 379.97377
= 380 feets apart
I'm not 100% sure of this I think its as follows:-
Prob(Lauren then Isabel picked) = 1/12 * 1/11 = 1/132
