The expression p/x^2 - 5x +6 simplifies to x+4/x-2. Which expression doees p represent?

Answers

we know that
(ad)/(bd)=d/d time a/b=a/b since d's cancel
also
if a/b=c/d in simplest form, then a=c and b=d

we have
p/(x^2-5x+6)=(x+4)/(x-2)
therefor

p/(x^2-5x+6)=d/d times (x+4)/(x-2)
p/(x^2-5x+6)=d(x+4)/d(x-2)

therefor
p=d(x+4) and
x^2-5x+6=d(x-2)

we can solve last one
factor
(x-6)(x+1)=d(x-2)
divide both sides by (x-2)
[(x-6)(x+1)]/(x-2)=d
sub

p=d(x+4)
p=([(x-6)(x+1)]/(x-2))(x+4)
$p= \frac {(x-6)(x+1)(x+4)}{(x-2)}$

I need to know the measurement of the fourth angle

Answers

Answer:

108° Make me Brainliest pls

Answer:

108 degrees

Step-by-step explanation:

All 4 angles of a quadrilateral added together is always equal to 360 degrees.

252 is the sum of 3 angles

therefore, in order to find the fourth measurment, we subtract 360-252

=108

At a dental office, the probability a patient needs a cleaning is 0.89. The probability a patientneeds a filling is 0.44. Assuming the events "needs a cleaning" and "needs a filling" are
independent, then what is the probability a patient needs a filling given that he/she needs a cleaning?
A. 0.83
B. Additional information is required to determine the probability.
C.0.39
D. 0.89
E. 0.44

Answers

Answer: 0.44

Reason:

The events "needs a cleaning" and "needs a filling" are independent. Therefore, we can immediately conclude that the prior condition "needs a cleaning" does not affect "needs a filling". That's why we go for the answer of 0.44 which is stated in the instructions.

In terms of symbols:

C = patient needs a cleaning
F = patient needs a filling
P(C) = 0.89 = probability the patient needs a cleaning
P(F) = 0.44
P(F given C) = P(F) .... since F and C are independent
P(F given C) = 0.44

The knowledge about event C happening does not change the value of P(F). Now if events F and C were dependent somehow, then P(F given C) would be different from P(F).

If a jelly bean machine contains 16 pink jelly beans, 34 blue jelly beans, 24 black jelly beans, and 26 purple jelly beans, what is the probability that a jelly bean chosen at random will be pink?

Answers

There are 16 pink jelly beans.
There are 16+34+24+26=100 jelly beans in total.

$P=(16)/(100)=16\% = (4 * 4)/(25 * 4)=(4)/(25)$

The probability is 4/25, or 16%.

Answer:

4/25

Step-by-step explanation:

The answer is 4/25
