Answer:

x = 8/3

Step-by-step explanation:

8^x = 256

Replace 8 with 2^3 and 256 with 2^8

2^3 ^x = 2^8

We know that a^b^c = a^(b*c)

2 ^ (3x) = 2^8

The bases are the same so the exponents are the same

3x= 8

Divide each side by 3

3x/3 = 8/3

x = 8/3

Answer: 8^(2+(2/3))

Step-by-step explanation:

2 to the 8th power of 256, and 8 to the 2nd power is 64. However, 8 to the third power is 512, which means that our answer has to be between 2 and 3. 8/3=2. Using an equation that works with all exponents of two (The exponenet that is right below the number we're looking for, or 2, in this case, plus ((number/exponent) will give us our answer. since 8/3 = 2, our answer will be 2+(2/3)

Answer:

Step-by-step explanation:

Use definition of conditional probability:

$P(A|B)=\dfrac{P(A\cap B)}{P(B)},$

where

A = the student is a freshman,

B = the student is a male

From the table,

$P(B)=\dfrac{4+6+2+2}{4+6+2+2+3+4+6+3}=\dfrac{14}{30}=\dfrac{7}{15}\\ \\P(A\cap B)=\dfrac{4}{4+6+2+2+3+4+6+3}=\dfrac{4}{30}=\dfrac{2}{15}$

So,

$P(A|B)=\dfrac{\frac{2}{15}}{\frac{7}{15}}=\dfrac{2}{7}\approx 0.29=29\%$

Answer:

Sasha can look at the graph and check to see that when she plots the points on the graph, they end up as a straight line. She can also draw a table to test the values and see if when you divide y/x you get the same answer for all of them.

Hey!

This could be rewritten as:

2x + 1 + 5x

We can add like terms together:

7x + 1
