If you need explaining think of it as....a number line. Zero is in the middle with negative numbers going down the left and positive numbers going down the right. Put a mark on -10 and move to the right 2 times. That would give you an answer of -8.

Hope this helps!
Let me know if i'm wrong.

Suppose rain is falling at an average rate of 30 drops per square inch per minute. What is the chance that a particular square i

borishaifa [10]

Answer:

Therefore the chance that a particular square inch is not by any drops during a given 10 second period is $e^{-5a}$ .

Step-by-step explanation:

Poisson distribution:

$P(X=x)= \frac{e^{-\lambda t} (\lambda t)^x}{x!}$

Given that rain is falling at an average rate 30 drops per square inches per minutes.

A reasonable choose of this distribution is Poisson distribution $(\lambda t)$ .

Let the area be a square inch.

Here $\lambda$ = average rate of rain drop × area

=(30×a)= 30 a

t = 10 second $= \frac{10}{60} \ minutes$ $=\frac16\ minutes$ .

Therefore,

$P(\textrm {no rain drop in }\frac16 \ minutes) =P(X=0)$

$=\frac{e^{-\frac{30a}{6}}.(\frac{30a}{6})^0}{0!}$

$=e^{-5a}$

Therefore the chance that a particular square inch is not by any drops during a given 10 second period is $e^{-5a}$ .

You and three friends go to a restaurant for dinner. You share three appetizers that cost $8 each. You also share two desserts t

Nikitich [7]

Answer:

Step-by-step explanation:

You and your friends = 4

Appetizers = 8*3 $ (3 appetizers)

Deserts = 4*2 $ (2 deserts)

Bill = 8*3 + 4*2

= 24 + 8

= 32 $

Each pays equally

= 32 / 4. ( 4 people are there)

= 8

So, you and your friends need to pay 8$ each to pay bill

HELP PLS I'LL MARK U BRAINLIST !!

Dahasolnce [82]

Answer:

angles in a triangle add up to 180°

5:12:13 = 30

180 ÷ 30 = 6

6 × 5 = 30°

6 × 12 = 72°

6 × 13 = 78°

angles = 30°, 72°, 78°
