Determine the units digit (ones digit) of the counting number represented by the exponential expression.

Oduvanchick [21]

The units digit of the given exponential expression will be 6

<h3>Determining the units digit of an exponential expression</h3>

From the question, we are to determine the units digit of the given exponential expression

The given exponential expression is

4⁸⁰⁰

We know that

4¹ = 4

4² = 16

4³ = 64

4⁴ = 256

4⁵ = 1024

4⁶ = 4096

From above, we can observe that the units digit of the odd exponents is 4 while the units digit of the even exponents is 6.

The exponent of the given expression is 800. 800 is an even number.

Hence, the units digit of the given exponential expression will be 6

A litter of puppies consists of black puppies and white puppies. A

BartSMP [9]

We want to see if the first selection is dependent on the second selection, we will see that no, the first selection can not depend on a selection that <u>did not happen yet.</u>

So the situation is:

We have a group of puppies, some are black, some are white.

Let's say that there are N puppies in total, n₁ are black, n₂ are white, such that:

n₁ + n₂ = N

Now we have that the first selection, event A, is a black puppy. The probability is just the quotient between the number of black puppies and the total number of puppies:

q = n₁/N

Then now we have:

N - 1 puppies in total.
n₁ - 1 black puppies
n₂ white puppies.

Now for the second selection, event B, the probability of selecting a white puppy is:

P = n₂/(N - 1)

Notice that because there are fewer black puppies than before (because we took one) the denominator decreases, thus, the probability of getting a white puppy increases.

So clearly event B depends on event A.

Now the question is:

Is A dependent on B?

No, A can not depend on event B, because event A happens first. The probability of the first event is always q = n₁/N.

Using the graph of f(x) = log2x below, approximate the value of y in the equation 22y = 5.

Naddika [18.5K]

The correct question is
Using the graph of f(x) = log2x below, approximate the value of y in the equation 2^(2y) = 5

we have
2^(2y) = 5--------------> applying base 2 logarithm both members
2y*log2(2)=log2(5)
log2(2)=1
then
2y=log2(5)
y=[log2(5)]/2

using the graph
for x=5 the approximate value of log2(5) is 2.3
see the attached figure
so
y=[log2(5)]/2--------> y=[2.3]/2----------> y=1.15

the answer is
the approximate value of y is 1.15
