What is the rational number?

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

A) The decimal number 3.456733244… is not repeating and non recurring

So, it is irrational number

B) The decimal number 3.4 terminating decimal

So, it is rational number

C) Infinity is not a rational number because it is undefined as far as being an integer.

D) ∛4 =1.58740105197 is not repeating and non recurring

So, it is irrational number

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

What is the answer to.. –2m = 8 − m

Answers

Answer:

-8

Step-by-step explanation:

Solve the equation:

-2m = 8 - m

-2m + m = 8

-m = 8

m = -8

If you would like to check the answer, plug the value of m back into the equation:

-2 (-8) = 8 - -8

16 = 16

Answer:

m = -8

Step-by-step explanation:

add m to both sides

-2m + m =8 - m + m

simplify

-m = 8

divide sides by -1

-m/-1 = 8/-1

simplify

m = -8

Hey there!

Your answer would be -32.5.

First, you would multiply both sides by 10, and simplify. That would bring you to 4x + 25 = 2x - 40. Now you can start isolating the varible. Subtract 25 from both sides, and simplify. That gives you 4x = 2x - 65. Next, subtract 2x from both sides, and simplify once again. That brings you to 2x = -65. Finally, divide both sides by 2 and once more, simplify. It gives you your answer x=-65/2 or -32.5

Write a sentence describing each of the following probabilities. (Note: A' = the complement of event A) P(A or A') = 1 P(A and A') = 0

Answers

Answer:

The following properties hold for all events A, B.

• P(∅) = 0.

• 0 ≤ P(A) ≤ 1.

• Complement: P(A) = 1 − P(A).

• Probability of a union: P(A ∪ B) = P(A) + P(B) − P(A ∩ B).

For three events A, B, C:

P(A∪B∪C) = P(A)+P(B)+P(C)−P(A∩B)−P(A∩C)−P(B∩C)+P(A∩B∩C).

If A and B are mutually exclusive, then P(A ∪ B) = P(A) + P(B).

• Conditional probability: P(A | B) = P(A ∩ B)

P(B)

.

• Multiplication rule: P(A ∩ B) = P(A | B)P(B) = P(B | A)P(A).

• The Partition Theorem: if B1, B2, . . . , Bm form a partition of Ω, then

P(A) = X

m

i=1

P(A ∩ Bi) = X

m

i=1

P(A | Bi)P(Bi) for any event A.

As a special case, B and B partition Ω, so:

P(A) = P(A ∩ B) + P(A ∩ B)

= P(A | B)P(B) + P(A | B)P(B) for any A, B.

• Bayes’ Theorem: P(B | A) = P(A | B)P(B)

P(A)

.

More generally, if B1, B2, . . . , Bm form a partition of Ω, then

P(Bj | A) = P(A | Bj )P(Bj)

Pm

i=1 P(A | Bi)P(Bi)

for any j.

• Chains of events: for any events A1, A2, . . . , An,

A passenger plane left the airport and flew
south at an average speed of 425 mph. A
cargo plane left sometime later flying in
the opposite direction with an average
speed of 302 mph. After the passenger
plane had flown for eight hours the planes
were 4608 mi. apart. How long did the
cargo plane fly?

Answers

Answer:

The cargo plane flew 1208 miles, and it took 4 hours.

Step-by-step explanation:

4608 miles is the distance between the passenger plane and the cargo plane.

This distance can be expressed as the sum of the distance that the passenger plane had flown and the distance that the cargo plane had flown.

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

So, to find the distance flown by the cargo plane, we need both the distance between the 2 planes and the distance flown by the passenger plane.

We know that the distance apart is 4608 mi.

How far did the passenger plane fly?

We can find the distance flown by the passenger plane by multiplying its speed by the time it was flying.

[tex]distance = speed * time[/tex]

Speed = 425 mph

Time = 8 hours

[tex]distance\ (passenger) = 425 * 8\\distance\ (passenger) = 3400[/tex]

The passenger plane flew 3400 mi.

How far did the cargo plane fly?

Now we can find the distance flown by the cargo plane:

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

[tex]4608 = 3400 + distance[/tex]

Subtract 3400 from both sides:

[tex]1208 = distance[/tex]

The cargo plane flew 1208 miles.

For how long did the cargo plane flow?

If we want to find for how long it flew, we can divide the distance by its speed.

[tex]distance = speed * time[/tex]

[tex]time = \frac{distance}{speed}[/tex]

Distance = 1208 mi

Speed = 302 mph

[tex]time = \frac{1208}{302} = 4[/tex]

Answer: The cargo plane flew 1208 miles, and it took 4 hours.

where is the vertex of y=3(x-26)^2+14?

Answers

The vertex is (26,14)

Because it’s written in vertex form which y=a(x-h)^2 + k. H is the x for the vertex And h is changed to it’s opposite. So since 26 is negative it would actually be positive 26. While k ls the y of the vertex which is 14 in our case

For each function, what is the output of the given input?
For f (x) =4x+7, find f(4)

Answers

Answer:

23

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23
