For the first question: All you have to do is count the rectangles! So, not including the shaded rectangle, there are 14 that are equal in size. (If your teacher wants you to include the shaded rectangle in your answer, it is 15.)

For the second question: You just have to put the number of shaded rectangles (1) as the top number, or numerator. Then, you put the total number of rectangles as the bottom number, or denominator (15), to get you an answer if 1/15 of the square.

For the third question: the area of the square is 1 meter, so the fractional answer would just be 1/1. You could do it with the rectangles, too, and get 15/15 which reduces to 1/1 as your final answer.

Hope this helps! Good luck!

Answer:

a) 3.6

b) 1.897

c)0.0273

d) 0.9727

Step-by-step explanation:

Rabies has a rare occurrence and we can assume that events are independent. So, X the count of rabies cases reported in a given week is a Poisson random variable with μ=3.6.

The mean of a Poisson random variable X is μ.

mean=E(X)=μ=3.6.

The standard deviation of a Poisson random variable X is √μ.

standard deviation=S.D(X)=√μ=√3.6=1.897.

The probability for Poisson random variable X can be calculated as

P(X=x)=(e^-μ)(μ^x)/x!

where x=0,1,2,3,...

So,

P(no case of rabies)=P(X=0)=e^-3.6(3.6^0)/0!

P(no case of rabies)=P(X=0)=0.0273.

P(at least one case of rabies)=P(X≥1)=1-P(X<1)=1-P(X=0)

P(at least one case of rabies)=1-0.0273=0.9727

Answer:

2 , 10 , and 15 in order of missing spaces, up to down

Step-by-step explanation:

You find the ration 8/20 and find out if the ration is simplifiable and turn it to 2/5 which you multiply the rest of the answers too. Hope this answers your question :)
