(3x^3 + 4x²) + (3x^3 – 4x^2 – 9x) =​

We have to combine like terms, terms that have x raised to the same power:

First, eliminate the parenthesis:

3x^3 + 4x² + 3x^3 – 4x^2 – 9x =​

We have 2 terms raised to the second power (4x^2 and -4 x^2) simply add and subtract.

3x^3+3x^3+4x^2-4x^2-9x

6x^3-9x

Six of the nine students are from middle gerogia state college. What is the probability that all three interviewed students are
ozzi

Answer:

0.2381 = 23.81%

Step-by-step explanation:

To calculate this probability, we can calculate the probability of each student of the 3 students interviewed being from middle georgia state college.

If inicially there are six students from middle georgia state college among the nine students, the probability of the first student chosen being from middle georgia state college is 6/9.

Then, as one student was already picked, we have now 5 students from middle georgia state college in a total of 8 students, so the probability of the second student will be 5/8.

In the same way, the third student will be picked in a group of 7 students, where 4 are from middle georgia state college, so the probability is 4/7.

Multiplying all the probabilities, we have the probability of all three students interviewed being from middle georgia state college:

P = (6/9) * (5/8) * (4/7) = 120/504 = 0.2381 = 23.81%

The sun is about 93x the sixth power of then miles from earth what is this distance written as a whole number?
AnnyKZ [126]

The number is written as

93 \times 10^6

To evaluate the power of ten, just remember that 10 to the power of n is a one followed by n zeroes, so ten to the sixth power is a one followed by six zeroes:

10^6=1000000

So, the number is

93 \times 1000000

When you multiply a number by a power of ten, you simply add the same number of zeroes after the number. So, in this case, you only need to add six zeroes after 93:

93 \times 1000000 = 93000000

which is 93 millions.
