Answer:

a. k = n - 1 b. 15 c. 112

Step-by-step explanation:

I can answer a. b. and c. for you!

For a. let's say that the variable k means keys. And n means bits.

Since Millie can collect one less keys than there are bits, the equation is....

*See top*

For b. if Antonio has a 16-bit system, by looking at our equation we know that k = n - 1.

So, if n = 16, k = 15

For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.

8 x 14 = 112

Answer:

$\displaystyle P=\frac{7}{15}=0.467$

Step-by-step explanation:

<u>Probabilities</u>

When we choose from two different sets to form a new set of n elements, we use the so-called hypergeometric distribution. We'll use an easier and more simple approach by the use of logic.

We have 6 republicans and 4 democrats applying for two positions. Let's call R to a republican member and D to a democrat member. There are three possibilities to choose two people from the two sets: DD, DR, RR. Both republicans, both democrats and one of each. We are asked to compute the probability of both being from the same party, i.e. the probability is

$P=P(DD)+P(RR)$

Let's compute P(DD). Both democrats come from the 4 members available and it can be done in $\binom{4}{2}$ different ways.

For P(RR) we proceed in a similar way to get $\binom{6}{2}$ different ways.

The total ways to select both from the same party is

$\displaystyle \binom{4}{2}+\binom{6}{2}=4+15=21$

The selection can be done from the whole set of candidates in $\binom{10}{2}$ different ways, so

$\displaystyle P=\frac{21}{\binom{10}{2}}$

$\displaystyle P=\frac{21}{45}=\frac{7}{15}=0.467$

Can someone help me on finding the measure of each angle please? I'm struggling alot on this! :(

olga_2 [115]

Answer:

Step-by-step explanation:

The protractor has inner and outer readings. The inner reading has graduations with intervals of 10 degrees and the outer reading also has graduations with intervals of 10 degree. We will use the outer graduations to take readings. On the outer reading, the shortest graduations is in intervals of 1 degree while the shorter graduation is in intervals of 5 degrees. Therefore,

a) angle AFB is 55 degrees

b) angle BFE is 180 - 55 = 125 degrees.

c) angle DFA is 126 degrees

d) angle BFD is 60 + 5 + 6 = 71 degrees.

e) angle CFD is 36 degrees

Determine whether each ordered pair is a solution to the inequality x+5y<2.

inna [77]

Two points ( -8,-1) and ( -1,0) are the solutions and the other points are not the solution to the inequality.

<h3>What is inequality?</h3>

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than.

Given inequality is:-

x + 5y < 2.

We will check all the points for the inequality:-

(−8,−1) → x + 5y < 2. → -8 +(5 x -1) < 2 → -13 < 2 It is inequality

(−1,0) → x + 5y < 2 → -1 < 2 It is inequality

(4,2) → x + 5y < 2 → 14 < 2 wrong

(9,6) → x + 5y < 2 → 39 < 2 wrong

(0,10) → x + 5y < 2 → 50 < 2 wrong

Therefore the two points ( -8,-1) and ( -1,0) are the solutions and the other points are not the solution to the inequality.
