Can someone help me with this ASAP

The weather in a certain locale consists of alternating wet and dry spells. Suppose that the number of days in each rainy spell

Amiraneli [1.4K]

Answer:

2/9

Step-by-step explanation:

The Poisson’s distribution is a discrete probability distribution. A discrete probability distribution means that the events occur with a constant mean rate and independently of each other. It is used to signify the chance (probability) of a given number of events occurring in a fixed interval of time or space.

In the long run, fraction of time that it rains = E(Number of days in rainy spell) / {E(Number of days in a rainy spell) + E(Number of days in a dry spell)}

E(Number of days in rainy spell) = 2

E(Number of days in a dry spell) = 7

In the long run, fraction of time that it rains = 2/(2 + 7) = 2/9

1. Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs the same amount, complete the tab

Lunna [17]

Answer:

1: $1.50

2: $3.00

4: $6.00

5: $7.50

6: $9.00

7: $10.50

8: $12.00

9: $13.50

Step-by-step explanation: To answer this problem you need to divide $4.50 by 3. When you do that you get $1.50 per pound of gummy bears. Then you can either add $1.50 to each amount or multiple them by the x value. Then graph the numbers you get.

What is the domain of the function? Domain: x

aleksley [76]

Answer:

Domain of a function as the possible values of x.

Step-by-step explanation:

When we define a function, we state to types of variable, the dependent variable and the independent variable.

If we have a function of the form $y = f(x)$ , here, x is the independent variable and y is the dependent variable, that is, y depends on x.

We define domain of a function as the possible values of x that is the independent variable. Thus, it is a set of all possible values of x such that the value of function f(x) or the value of y is defined.

To find the domain of a function, we should try to find all possible values x can take such that y is defined.

Example: In a function consisting of fraction we should choose the domain in such a manner that the denominator is not zero.

Its for science but its got math involved its got to do with speed distance and time

KIM [24]

distance:1, 1, 1.3, 1.5, 2, 2.3, 2.5, 3 ,3.2, 4

time. :1, 2, 3 , 4 , 5 , 6 , 7 , 8 ,. 9 ,10

distance:1.5, 2, 3.2, 4.2, 5, 6, 7, 8

time. : 1 , 2, 3 , 4. , 5, 6, 7, 8

<h3>at 5 seconds which travelled the greatest distance : snail 2</h3>

<h3>which travelled a greater distance:snail 2</h3>

<h3>what is the speed of snail 1 at 8 second :</h3>

distance = 3. Time = 8

speed = distance

time

speed = 8

3

speed =2.66

approximately = 2.7. or 3
