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 =
i.e. 1/100 chance of getting bitten in one second
In 100 seconds number of bites
Expected time between successive bites = 100
Y=-1/2x-3
You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b
Why y equals 2 is Function
Answer: In general, a relationship f(x) =y is a function only if, for each value of x that you plug into it, you get only one value for y.

The surface area of the triangular prism is of 162 cm².
<h3>What is the surface area of a prism?</h3>
The surface area of a prism is given by the sum of all the areas of the prism.
This prism is composed by:
- One rectangle of dimensions 10 cm and 7 + 6 + 4 = 15 cm.
- Two right triangles, of sides 6 cm and 4 cm.
For a rectangle, the area is the multiplication of the dimensions, hence:
A1 = 10 x 15 = 150 cm².
For a right triangle, the area is half the multiplication of the sides, hence:
A2 = 0.5 x 6 x 4 = 12 cm².
Hence the surface area is:
A = A1 + A2 = 150 cm² + 12 cm² = 162 cm².
