Step-by-step explanation:
Natural numbers are positive integers
1,2,3,4,5.......
We need those that are less than 6
{1,2,3,4,5}
Answer:
It's D: 1,2,3,4,5.
Step-by-step explanation: A natural number is a positive number that is not 0, and choices A and B have 0 in them, so we can eliminate those choices. For choice C, the question says that x is a natural number less than 6, so it can't include 6. So, we can eliminate Choice C and we are left with Choice D. Your answer is D. Hope this helped
Tell whether the tables show a proportional relationship between x and y
Answer:
Yes
Step-by-step explanation:
Everything in the "x" row is being multiplied by 3.
Explanation:
Divide each y value over its corresponding paired x value
First column: y/x = 3/1 = 3
Second column: y/x = 6/2 = 3
Third column: y/x = 9/3 = 3
Fourth column: y/x = 12/4 = 3
Each time we get the same result, so k = y/x = 3 is the constant of variation
The equation is y = 3x which is in the form y = kx with k = 3.
For instance, if x = 4, then y = 3x = 3*4 = 12.
All direct proportional relationship equations are linear and go through the origin.
job interview: six people, named anna, bob, chandra, darnell, emma, and francisco, will be interviewed for a job. the interviewer will choose two at random to interview on the first day. what is the probability that emma is interviewed first and bob is interviewed second? express your answer as a fraction or a decimal, rounded to four decimal places.
The probability that Emma is interviewed first and Bob is interviewed second is 1/90 or 0.0111 (rounded to four decimal places).Hence, the correct option is A. 1/90.
Given:Six people, named Anna, Bob, Chandra, Darnell, Emma, and Francisco, will be interviewed for a job. The interviewer will choose two at random to interview on the first day.
To find:Probability that Emma is interviewed first and Bob is interviewed second.Solution:Total number of ways to choose 2 out of 6 people = 6C2 (using combination formula)
Number of ways Emma is interviewed first and Bob is interviewed second = 1 (since we are given that)Number of ways interviewer can choose 2 people out of remaining 4 = 4C2 (using combination formula)
Total number of ways = 6C2 × 4C2 = (6 × 5 / 2 × 1) × (4 × 3 / 2 × 1) = 15 × 6 = 90 ways
The probability of selecting two candidates, if there are six candidates available, is therefore, (2/6) * (1/5) = 1/15. (Probability of Emma being chosen on the first day multiplied by the probability of Bob being chosen on the second day)

A Bernoulli random variable (RV) is a binary event that occurs with a certain probability. If the event happens, the Bernoulli RV is 1, and if it doesn't happen, the RV is 0. Bernoulli RVs are used in probability theory to model random variables that have two possible outcomes. A Bernoulli RV is an important building block for other probability distributions, such as the binomial distribution , which is used to model events that occur a certain number of times in a row, such as coin flipping.
In addition to the examples given in the text, there are a few other examples of Bernoulli RVs. The first example is X = 1 if a randomly selected book is fiction and X = 0 otherwise. This Bernoulli RV models the probability that a randomly selected book from a library is a work of fiction. The second example is xthe number of lightbulbs that needs to be replaced in a randomly selected building and X-O if there are none. This Bernoulli RV models the probability that a light bulb needs to be replaced in a building. Finally, the third example is x = 1 if a randomly selected driver has automobile insurance and X = 0 otherwise. This Bernoulli RV models the probability that a randomly selected driver has car insurance.
Bernoulli RVs are used to model binary events with a certain probability of occurrence.

.Which expression is the result of solving the equation ax-b=cy for x? (For a ≠ 0)
a) cy + b/a
b) cy + b/a
c) cy/a + b
d) cy-b/a
option (A) cy + b/a is the main answer.
The given expression ax - b = cy is an equation with one variable 'x.'
We need to find the value of x. The steps to solve the equation are given below:
Solve for x:Adding 'b' to both sides,ax = cy + b.
Divide both sides by 'a,'x = (cy + b) / a.\
Therefore, option (A) cy + b/a is the main answer.
Therefore, we can conclude that the result of solving the equation ax - b = cy for x is x = (cy + b) / a, and the main answer is option (A) cy + b/a.

Find the equilibrium quantity.
hundred units
Find the equilibrium price.
the equilibrium quantity is 20 hundred units and the equilibrium price is $89.
The weekly demand and supply functions for Sportsman 5 X 7 tents can be represented as:
p = 0.1x² - x + 69 (Demand Function) and
p = 0.1x² + 2x + 49 (Supply Function)
We can find the equilibrium quantity by equating both functions:
Demand Function = Supply Function
0.1x² - x + 69 = 0.1x² + 2x + 49- x - 2x
= 49 - 69-x = -20x = 20
On substituting the value of x in any of the above functions, we can get the equilibrium price:
p = 0.1x² - x + 69
= 0.1(20)² - (20) + 69 = $89
Therefore, the equilibrium quantity is 20 hundred units and the equilibrium price is $89.

Step-by-step explanation:
the distance from the epicenter of the march 1964 earthquake to crescent city is 2600 kilometers. how long did it take the first p-wave to reach crescent city
The distance from the epicenter of the march 1964 earthquake to crescent city is 2600 kilometers and It took 400 seconds for the first p-wave to reach crescent city
In a seismic event like an earthquake, seismic waves propagate through the Earth at different speeds. The first type of seismic wave to reach a particular location is the primary wave, or P-wave. P-waves are compressional waves that travel faster than other seismic waves, such as S-waves or surface waves.
To calculate the time it took for the P-wave to reach Crescent City, we need to know the speed at which P-waves travel. On average, P-waves travel at a speed of about 6-7 kilometers per second in the Earth's crust. However, this speed can vary depending on the specific properties of the Earth's layers.
Using an average speed of 6.5 kilometers per second, we can calculate the time it took for the P-wave to travel a distance of 2600 kilometers:
Time = Distance / Speed = 2600 km / 6.5 km/s ≈ 400 seconds.
Therefore, it took approximately 400 seconds, or 6 minutes and 40 seconds, for the P-wave to reach Crescent City from the epicenter of the March 1964 earthquake.
It is important to note that the calculated time is an estimation based on average values, and the actual time may vary depending on the specific geological conditions along the propagation path of the P-wave.

Find the value of C that completes the square for x^2-2x + C
Answer:
C = 1.
Step-by-step explanation:
x^2 - 2x = (x - 1)^2 - 1 so:
x^2 - 2x + C = (x - 1)^2 - 1 + C
So to get a perfect square C must be 1 ( as -1 + 1 = 0):-
(x - 1)^2 - 1 + 1 = (x - 1)^2
Checking this:
x^2 - 2x + 1
= (x - 1)(x - 1) which is a perfect square./

Punctele O, A, B, C sunt coliniare în această ordine, iar segmentele OA, AB și BC au lungimile exprimate în cm, prin numere naturale pare consecutive. Se știe că M este mijlocul segmentului AC și OM = 11 cm. Calculați: a) lungimea segmentului OC; b) distanța dintre N, mijlocul segmentului OB, și punctul M.
Răspuns:
a) OC = 18cm
b) MN = 6cm
Explicație pas cu pas:
Găsiți diagrama la întrebarea atașată.
a) Din diagramă se poate observa că OC = OA + AB + AC
OC = 2n + 2n + 2 + 2n + 4
OC = 6n + 6
Următorul este să obțineți valoarea lui n:
OM = OA + AM
Să obținem segmentul AM;
Deoarece M este segmentul mijlociu al AC, atunci;
AM = AC / 2
AM = AB + BC / 2
AM = 2n + 2 + 2n + 4/2
AM = 4n + 6/2
AM = 2n + 3
Din moment ce OM = OA + AM
OM = 2n + 2n + 3
OM = 4n + 3
Dat fiind OM = 11
11 = 4n + 3
4n = 11-3
4n = 8
n = 2
Următorul pas este să calculați OC;
OC = 6n + 6
OC = 6 (2) + 6
OC = 18
Prin urmare, lungimea segmentului OC este de 18 cm
b) Această întrebare ne cere să găsim segmentul de linie MN.
Din diagramă, MN = AM - AN
Deoarece AM = 2n + 3 din întrebarea 1;
AM = 2 (2) +3
AM = 4 + 3
AM = 7
Acum, să obținem AN:
Din diagramă, AN = ON-OA și ON = OB / 2
AN = OB / 2 - OA
AN = (2n + 2n + 2) / 2 - 2n
AN = 4n + 2/2 - 2n
AN = 2n + 1 - 2n
AN = 2n-2n + 1
AN = 1
De la MN = AM - AN
MN = 7 - 1
MN = 6cm
Prin urmare, distanța dintre N, mijlocul segmentului OB și punctul M este de 6cm
