Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the
bagirrra123 [75]

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down

A fair coin is continually flipped until heads appears for the 10th time. Let X denote the number of tails that occur. Compute t
Ierofanga [76]

Answer:

The probability mass function is expressed as:

P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]

Step-by-step explanation:

This is not a binomial distribution. It is actually a negative binomial distribution. The probability mass function is expressed below:

P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]

where:

x = number of failures

r-1 = number of successes (10 in this scenario)

p = probability of a success

nCr = n!/[r!(n-r)!]

The main formula difference in the positive binomial versus negative binomial is this: With respect to the negative binomial, it is obviously  known that the last event will be: when we reach our 10th "head", we stop .

Thus, the last flip will ALWAYS be a "head".
