The tree diagram represents an experiment consisting of two trials.<br><br>P(A and C) = [?]
schepotkina [342]

Yo sup??

To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C

P(A)=0.6

P(C|A)=0.3

P(A and C)=0.6*0.3

=0.18

Hope this helps.

andriy [413]

Answer:

Initial value is \frac{1}{2}.

Step-by-step explanation:

Let us assume that the exponential function is f(x) = a(b)^{x} ...... (1)

Now, the point (0,\frac{1}{2}) will satisfy the above equation.

Now, this point on the graph of the exponential function will be sufficient to find the initial value of the function (1) i.e. a.

Now, putting the value x = 0 and y = \frac{1}{2} in the equation (1) we get, f(x) = a(b)^{x}

⇒ \frac{1}{2} = a(b)^{0} = a

⇒ a = \frac{1}{2} (Answer)

can someone please do this for me and tell me how so I can do the other one pleaseeee I don't know what to do
KonstantinChe [14]

Answer:

P(green) =1/4

P(orange)=1/2

Step-by-step explanation:

I'm assuming this is probability but it\s been a while, so i'm not sure

number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)

so the probablity of landing in green is 1/4, because it is one fourth of the square.

the probability of the orange is 1/2 because it is 1/2 of the square

The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.

Hope that helps.

Calculate the 95% confidence interval for the slope. o (-0.327, 0.00) o (-0.305,-0.022) o (-0.308,-0.019) o (-0.322,0.021)
d1i1m1o1n [39]

The 95% confidence interval for the slope will be B. (-0.308,-0.019).

<h3>How to calculate the interval?</h3>

The confidence interval based on the information and diagram will be:

= -0.1636 + 2.228 × 0.06488

= 0.019

Also, -0.1636 - 2.228 × 0.06488

= -0.308

In conclusion, the correct option is (-0.308,-0.019).
