Find the mean and the median of this data set: 8, 6, 6, 3, 72, 7, 4, 2

icang [17]

Answer:

median: 6 ; mean: 13.5

Step-by-step explanation:

The median is where you line up the numbers from least to greatest and add the 2 that are left since it was an even number and you get 6. The mean is where you add all 8 numbers and divide by 8, since that is how many numbers there are.

Find x such that 3^x = 27 mod 32 (b)

gregori [183]

Answer:

The value of x is 11.

Step-by-step explanation:

Consider the provided information.

It is given that $3^x = 27 mod\ 32$

We know that:

$3^4=81$

Now if we divide the number 81 with 32 it will gives us remainder 17.

This can be written as:

$3^4\equiv 17(mod\ 32)$

Now use the property: $a^n\equiv b^n(mod\ m)$

$(3^4)^2\equiv 17^2(mod\ 32)$

17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.

$3^8\equiv 1(mod\ 32)$

Multiply both the sides by 3³.

$3^8\times 3^3\equiv 3^3(mod\ 32)$

$3^{11}\equiv 27(mod\ 32)$

Hence, the value of x is 11.
