Answer:

X = 9

Step-by-step explanation:

4 + 3 + 4 + 6 + 1 + x / 6 = 4.5

18 + x / 6 = 4.5

cross multiply

18 + x = 4.5 × 6

18 + x = 27

collect like terms

x = 27 - 18

x = 9

If logb 5=0.41, find logb 12
Hitman42 [59]
<span>Determine which one of the following is the correct application of the change of base formula?

a)log3 14= log10 14/3
b)lo4 17= log10 4/ log10 17
c)log8 3= log10 3/log10 8
d)log9 32 = log10 32-log10 9

The change of base formula is as follows:
                                         log to the base 10 of x
log to the base b of x  = ----------------------------------
                                          log to the base 10 of b

Compare this to answer choice C:

</span><span>c)log8 3= log10 3/log10 8      Here x = 3 and b = 8.  This is the only correct choice.</span><span>

Consider the following events for a driver selected at random from a general population.
adoni [48]

Answer:

a. P(AnB)

b. P(B|A)

c. P(A^I|B)

d. P(A or B)

e. P(B^I or A)

Step-by-step explanation:

Since  A= driver is under 25 years old (1)

B = driver has received a speeding ticket (2)

a.The probability the driver is under 25 years old and has recieved a speeding ticket.

this simple means the intersection of both set, which can be written as

P(AnB)

b. The probability a driver who is under 25 years old has received a speeding ticket.

This is a conditional probability, probability that B will occur given that A as occur.

P(B|A)

c. the probability a driver who has received a speeding ticket is 25 years or older.

P(A^I|B)

d. The probability the driver is under 25 years old or has received a speeding ticket.

P(A or B)

e. The probability the driver is under 25 years old or has not received a speeding ticket.

P(B^I or A)
