Answer with explanation:

Point, (7,-7,-4) lies in three Dimensional Coordinate system.

There are Eight Oct ants in three Dimensional System which are , X Y Z, X Y Z', X Y' Z, X'Y Z, X'Y'Z, X Y'Z',X'Y Z',X'Y'Z'.

X,Y ,Z=Positive Values on Axes including Zero.

X',Y',Z'= Negative value on Axes.

→→Point , (7,-7,-4) can be Described as:

7 Units Forward on X axis on Positive X axis, -7 units back on Y axis that is on Negative Y axis, -4 Units Downward on Z axis that is along negative Z axis.

Option A: 7 units forward,7 units back and 4 units down

LenaWriter [7]

Answer:

$P(A_{1}|B ) =\frac{mp}{1+p(m-1)}$

Step-by-step explanation:

For mutually exclusive events as A1, A2, A3, etc, Bayes' theorem states:

$P(A|B)= \frac{P(B|A)P(A)}{P(B)}$

P(A|B) is a conditional probability: the likelihood of event A occurring given that B is true.

P(B|A) is a conditional probability: the likelihood of event B occurring given that A is true.

P(A) is the probability that A occurs

P(B) is the probability that B occurs

For this problem:

A1 is the probability that the student knows the answer

A2 is the probability that the student guesses the answer

B is the probability that the student answer correctly

$P(A_{1})=p \\P(A_{2})=1-p \\P(B|A_{1})=1 \\P(B|A_{2})=\frac{1}{m} \\P(B)= P(A_{1})P(B|A_{1}) + P(A_{2})P(B|A_{2})= p+\frac{1-p}{m} \\$

P(B|A₁) means the probability that the answer is correct when he knew the answer

P(B|A₂) means the probability that the answer is correct when he guessed the answer

P(A₁|B) means the probability that he knew the answer when the answer was correct

Replacing everything in the Bayes' theorem you get:

$P(A_{1}|B)= \frac{P(B|A_{1})P(A_{1})}{P(B)}=\frac{(1)(p)}{p+\frac{1-p}{m}} =\frac{mp}{mp+1-p} =\frac{mp}{1+p(m-1)}$

Simplify 7h^2+6h^2+5h^2+6h^2-h^2

iogann1982 [59]

Answer:

23h^2

Step-by-step explanation:

These are all like terms so we add/subtract them from left to right.

7h^2+6h^2+5h^2+6h^2-h^2

= 24h^2 - h^2

= 23h^2 (answer)
