Go to lesson page Problem If you flip three fair coins, what is the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip?

Answers

Answer 1

The probability of any particular sequence of N flips of a fair coin is 2^(-N).

Your probability of the given sequence of 3 coin flips is
2^-3 = 1/8

Answer 2

First if all, we know that the coin has two sides- head and tail

P(getting a head of the first flip):

1/2

P(getting a tail on the second flip):

1/2

P(getting a head on the third flip):

1/2

To find the final answer, take:

1/2×1/2×1/2=1/8

As a result, the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip is 1/8. Hope it help!

Let f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k where a, b,c, and m are constants.
a.suppose that the flux of f through any closed surface is 0. which of the constants can be determined?

Answers

Let [tex]\mathcal R[/tex] be an arbitrary closed region with boundary the surface [tex]\mathcal S[/tex]. By the divergence theorem,

[tex]\displaysytle\iint_{\mathcal S}\mathbf f(x,y,z)\cdot\mathrm d\mathbf S=\iiint_{\mathcal R}\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV[/tex]

We have

[tex]\nabla\cdot\mathbf f(x,y,z)=\dfrac{\partial(ax+by+4z)}{\partial x}+\dfrac{\partial(x+cz)}{\partial y}+\dfrac{\partial(9y+mx)}{\partial z}=a[/tex]

so that the flux satisfies

[tex]\displaystyle a\iiint_{\mathcal R}\mathrm dV=0[/tex]

We're assuming [tex]\mathcal R[/tex] is a closed region, and the integral above is its volume, which must be positive. This means we must have [tex]a=0[/tex].

Final answer:

If the flux of a vector field through a closed surface is zero, this implies that the divergence of the field is zero everywhere. This condition can be used to determine some constants of the vector. In the provided equation, we can determine one of the constants a, c or m if we know the other two.

Explanation:

The subject matter of this question is within vector calculus, a field of mathematics used in physics and engineering. The question talks about the flux of a vector field f through a closed surface which is given to be zero.

When the flux through any closed surface is zero, it implies that the divergence of the vector field f is zero everywhere. This condition allows us to determine some of the coefficients of the components of f. In this case, we have: f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k

The operation that gives the divergence of a vector field in three-dimensional Cartesian coordinates is given by the dot product of the del operator with the vector field. This means:

div f = ∂/∂x(ax+by+4z) + ∂/∂y(x+cz) + ∂/∂z(9y+mx) = a + c + m

For the flux of f through the surface to be zero, the divergence of f needs to equal zero, that is a + c + m =0. Therefore, for a given set of a, c, and m, we can determine one of them knowing the others.

In a class of 40, 28 passed their maths test. What fraction of the class passed?

Answers

Final answer:

Out of a class of 40 students, 28 passed their maths test. The fraction of the class that passed the test is 28/40, which simplifies to 7/10.

Explanation:

The class consists of 40 students. The problem mentions that 28 of these students passed their maths test. To find the fraction of the class that passed, we have to compare the number of students who passed with the total number of students in the class. This is done by dividing the number of students who passed the test by the total class size. So, the fraction of the students who passed is 28/40. However, this fraction can be simplified by dividing both the numerator (28) and the denominator (40) by their greatest common divisor, which is 4. The result is 7/10. Therefore, the fraction of the class that passed the maths test is 7/10.

r(n) = (450 +50n)*(20 +n^2/45) = (10/9)n^3 +10 n^2 +1000n +9000
The cost for the production of all radios sold is given. Profit is then ...
(profit in year n) = (revenue in year n) - (cost in year n)
(profit in year n) = (10/9)n^3 +10n^2 +1000n +9000 -(1000 +10n^2)

2.56 + 1 = 3.56

The appropriate choice is ...
c. 3.56

Answer:

missing value in the table is 3.56

Step-by-step explanation:

Percent 13% 256% 28% 97%

Growth Factor 1.13 ? 1.28 1.97

To find growth factor first we remove the percentage and then we add 1

we are given with 246 %

to remove percentage we divide by 100

[tex]\frac{256}{100} = 2.56[/tex]

To get growth factor we add 1

1+2.56= 3.56

so growth factor is 3.56

Answers

the correct question is
The raised vegetable garden in Susan's yard is in the shape of a rectangular prism with a volume of 48 cubic feet and a height of 3/4 foot. The base of the rectangular prism is not a square and the width is greater than 2 feet. What is the length and width of the rectangular prism?

let
x-------> the length of the base of the rectangular prism
y-------> the width of the base of the rectangular prism

we know that
volume of the prism=area of the base*height
volume=48 ft³
height of the prism=3/4 ft

area of the base=volume/height--------> 48/(3/4)---> 48*4/3----> 64 ft²

area of the base=64 ft²
area of the base=x*y
64=x*y--------> equation 1

y=x+2--------> equation 2

substitute equation 2 in equation 1
64=x*[x+2]-----> 64=x²+2x------> x²+2x-64=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
x=7.062 ft
y=x+2-----> y=7.062+2-----> y=9.062 ft

the answer is

Two events are occurring:

1) Rolling a die
Sample Space = {1,2,3,4,5,6}
Total number of outcomes in sample space = 6
Favorable outcomes = Odd number
Number of Favorable outcomes = 3

Probability of getting an odd number = 3/6

2) Tossing a coin
Sample Space = {H, T}
Probability of getting a head= 1/2

The probability of getting odd number and head will be the product of two probabilities, which will be = 3/6 x 1/2 = 3/12

Thus there is 3/12 = 1/4 (0.25 or 25%) probability of getting an odd number and a head in given scenario.

So correct answer is option C

Three of the six numbers on the die are odd, so the probability of rolling an odd number is 3/6.

One of the two sides of the coin is a head, so the probability of tossing a head is 1/2.

These are considered to be independent events, so the joint probability is the product of these probabilities.

The probability of getting an odd number and a head is
(3/6)*(1/2) = 3/12

The appropriate choice is ...
C. 3/12

Cody is twice as old as Evan and seven years ago the sum of their age was 7. find the age of each boy now

Answers

Cody: 2x
Evan: x

x-7 (Evan’s age 7 years ago (-7))
2x-7( Cody’s age 7 years ago (-7))

So you add both
x-7+2x-7
And that should equal 7 (seven years ago the sum of their age was 7)
x-7+2x-7=7
3x-14=7
3x=21
x=7

Evan (x)= 7
Cody (2x)= 7 times 2
Cody= 14

Cody is currently 14 years old and Evan is 7 years old, as determined by setting up an equation based on the information provided and solving for their ages.

Let's set up an equation to solve this problem by letting the current age of Evan be x. Since Cody is twice as old as Evan, Cody's current age would be
2x. We are told that seven years ago, their ages added up to 7. Therefore, we can express this as (x - 7) + (2x - 7) = 7. Simplifying this equation gives us 3x - 14 = 7. Adding 14 to both sides gives us 3x = 21. Dividing both sides by 3 gives us x = 7, which is Evan's current age. Therefore, Cody's age is 2x which is 2*7 = 14. Cody is 14 years old and Evan is 7 years old now.

Answer:
expanded horizontally by a factor of 3, horizontal shift rith 6, vertical shift up 3

Answer:

C. Compressed horizontally by a factor of 1/3, horizontal shift right 2, vertical shift up 3

Step-by-step explanation:

If a function f(x) is transformed and make f(kx),

f(x) is compressed horizontally by the factor 1/k if k > 1

f(x) is stretched horizontally by the factor 1/k if 0 < k < 1

Also, if f(x) is transformed and make f(x+a),

f(x) is shifted right if a < 0

f(x) is shifted left if a > 0,

Now, if f(x) gives f(x) + k after transformation,

f(x) is shifted vertically k unit up if k > 0,

f(x) is shifted vertically k unit down if k < 0,

Here, the parent function,

[tex]f(x) = x^2[/tex]

transformed function,

[tex]g(x)=(3x-6)^2+3=(3(x-2))^2+3[/tex]

Thus, by the above explanation,

f(x) is compressed horizontally by a factor of 1/3, horizontal shift right 2, vertical shift up 3.
