We define variables:
 x: number of hats
 y: number of scarves
 We have the following equations:
 x / y = 4/3
 x-25 / y = 7/9
 Solving the system of equations we have
 x = 60
 y = 45

You are visiting a rainforest, but unfortunately,your insect repellent has run out. As a result, at each second, a mosquito land
zmey [24]

Answer:

Step-by-step explanation:

Prob at each second, a mosquito lands on your neck =0.5

Prob it bites/it lands = 0.2

Prob it does not bite/it lands = 0.8

Hence in one second prob for getting a bite = 0.5(0.2) = 0.01

i.e. 1/100 chance of getting bitten in one second

In 100 seconds number of bites =1

Expected time between successive bites = 100

Indicate, in standard form, the equation or inequality that is shown by the graph. (0,4)(4,0)
Len [333]
(0,4)(4,0)
slope = (0 - 4) / (4 - 0) = -4/4 = -1

y = mx + b
slope(m) = -1
use either of ur points....(0,4)...x = 0 and y = 4
sub and find b, the y int
4 = -1(0) + b
4 = b

equation is : y = -x + 4....in standard form, it is : x + y = 4
