What is the solution of log2 (3x-7) =3

Mathematics

Valentin [98]3 years ago

Answer:

x = 5

Step-by-step explanation:

because the log is base 2 you can remove the log by raing 2 to the power of each side:

2^{log2 (3x-7)} = 2^{3}

the 2 and log2 cancel leaving:

3x-7 = 2^{3}

this means we can now solve through simple algebra:

3x-7 = 8\\3x = 8 + 7\\3x = 15\\3x/3 =15/3\\x = 5

Julli [10]

Answer:

Step-by-step explanation:

2 out of 12 means also 1 out of 6.

so, a ratio of 1:6 or a factor of 1/6.

150 × 1/6 = 150 / 6 = 25

so, we expect that out of the 150 sold cars 25 have been red.

How many times could you expect to roll a number that is not 5 if you rolled a standard die 360 times?
Alinara [238K]

The number of times I would expect to roll a number that is not a 5 is 300 times.

<h3>What is the number of times a 5 won't be rolled?</h3>

A standard die has 6 faces. There are 5 numbers that are not 5 on a standard die. They are 1, 2, 3, 4, 6.

The number of times a 5 won't be rolled = (5/6) x 360

5 x 60 = 300 times

Round your answer to the nearest hundredth.
DanielleElmas [232]

Answer:

36.87°

Step-by-step explanation:

sin(A)/a = sin(C)/c

sin(x)/3 = sin(90)/5

sin(x)/3 = 0.2

sin(x) = 0.6

x= sin^-1(0.6)

x = 36.86989765
