If a classroom has 8 light bulbs and the probability that each individual light bulb works is 0.8 and each light bulb works independently of the other light bulbs then the probability that all 8 of the light bulbs work is equal to 0.1678.

Probability is a branch of mathematics and can be defined as the one which deals with the explanation of the possibility of an event to occur or take place. Probability has a range between 0 to 1. In probability, 0 indicates the impossibility of an event to occur and 1 indicates the certainty of that event to occur or take place.

As the light bulbs are not dependent on each other and work independently, the probability that all eight of the light bulbs will work can be calculated by multiplying the probability of each of the eight light bulbs.

As the probability of each of the eight light bulbs to work = 0.8

probability all the eight light bulbs work = 0.8^8

probability all the eight light bulbs work = 0.1678

Hence, 0.1678 is the probability that all the light bulbs work.

Step-by-step explanation:

If the two cities are 381 miles apart and speed of Jermaine is 67 miles per hour and the speed of David is 60 miles,then they will meet at 10:46 A.M.

Given that the two cities are at a distance of 381 miles and they start at 8:00 am in the morning.

We are required to find the time at which Jermaine and Brandon.

let the distance that Jermaine covers be x. In this way the distance that is covered is 381-x.

Time=Distance/speed

x/67=(381-x)/60

60x=67(381-x)

60x=25527-67x

137x=25527

x=25527/137

x=186.33

Distance that is covered by Brandon=381-186.33

=144.67 miles

Time taken by David=x/67

=186.33/67

=2.78 hours

We have to break an hour in 78% which is 46.8 minutes.

Actual time=(8+2)hours+46.8 minutes=10:46 A.M.

So, For this purpose, we know that the

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

From the given information:

Company A charges $45 per hour and a $300 equipment fee. Company B charges

$70 per hour and a $200 equipment fee.

Then

Let A(t) = 45t + 300

Let B(t) = 70t + 200

We can determine time t when both companies charge the same rate by equating the two equations.

45t + 300 = 70t + 200

Subtract 25t from both sides and subtract 150 from both sides

25t = 100

Divide both sides by 25

Answer: The difference of temperature (T) = 91° celsius.

Step-by-step explanation:

Phalodi, in Rajasthan, recorded one of India's highest temperatures is = 51 celsius.

Drass, in Kashmir, recorded one of India's lowest temperatures is = -40° celsius.

Find out the difference of two temperatures.

Let us assume,

                Rajasthan temperature = T1

                 Kashmir temperature = T2

Then,

we can write,

India's highest temperatures Rajasthan = (T1) = 51° celsius.

India's lowest temperatures Kashmir = (T2) = -40° celsius.

Then, the difference of temperature is equal to the difference between India's highest temperatures Rajasthan to India's lowest temperatures Kashmir.

So,

we can write,

difference of temperature (T) = Rajasthan temperature - Kashmir temperature

                                       T = T1 - T2  

                                       T = 51 - (-40)

                                       T = 51+40

                                      T =  91° celsius.

Therefore, the difference of temperature (T) = 91° celsius.

For a 75% success percentage, she needs to hit 23 of her final 30 throws.

The rational function for a player's free throw percentage will be:

y = (21/30) * 100

A function that is the sum of polynomials is referred to as rational. If a function of one variable, x, can be written as :

[tex]f(x) = p(x)/q(x),[/tex]

where p(x) and q(x) are polynomials with q(x) = 0,

then the function is said to be rational. The phrase f(x) = (x2 + x - 2) / (2x2 - 2x - 3) denotes a rational function; in this case, 2x2 - 2x - 3 = 0.

Every constant is a polynomial, thus we know that the numerators of rational functions may also be constants. A rational function would be f(x) = 1/(3x+1), for instance.

If the basketball player is making 70% successful throw rate by making 21 of last 30 free throws

so, for raising her throw rate to 75% she should throw:

x/30 * 100 = 75%

x = 75 * 3 / 10

x = 15 * 3 /2

x = 22.5 ≈ 23

therefore , she should make 23 of her last 30 free throws to raise her success rate to 75%

For this case what you should do is write the following function:

y = (a / b) * 100

Where,

A: amount of successful free throws

B: total amount of free throws

Substituting values we have:

y  = (21/30) * 100

The result is:

Y = 70% (as we expected)

a rational function that can model the player's free throw percentage is:

y = (21/30) * 100

The length of BD is 5√2

AB = 5cm

It is given that AB = BF = FD = 5cm

∠A = 60° and ∠BFA = 60°( as the side are equal then the angle opposite to it will be equal )

Hence we get ΔAFB as an equilateral angle

∠BFA + ∠BFD = 180°

60° + ∠BFD = 180°

∠BFD = 120°

It is given that BF = FD, so in ΔBFD we have

∠B + ∠D +∠F = 180

∠B = ∠D

2∠B + 120° = 180

2∠B = 60°

∠B = 30°

cos Ф = base / hypotenuse

Now from ΔBFC, we get

cos 30° = BC / BF

√3/2 = BC / 5

BC = 5√3/2

Now from ΔFDB, we get

cos 30° = CD/ FD

√3/2 = CD/ 5

CD = 5√3/2

BD = BC + CD

     = 5√3/2 + 5√3/2

     = 5√3

Therefore the length of BD is 5√3.

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward way.

The amount of times a number has been multiplied by itself is shown by its exponent.

Given the lowest altitude of an alto cumulus cloud is about 3⁸ feet. The highest altitude of an altocumulus cloud is about 3 times the lowest altitude.

To find the highest altitude of an altocumulus cloud, we must solve as follows:

Let the lowest altitude be x. Then,

3⁸ = x

The highest altitude will be 3x which is 3(3⁸).

⇒3(3⁸) = 3x

⇒3(6561) = 3x

Step-by-step explanation:

And substituting that would make this point become the equation, [tex]\frac{-\pi }{2}[/tex] which is our assumed midpoint and that would also equal [tex]-1 + -1 + 1 + 0(?)[/tex] and that would substitute in for 0 due to the fact of our midpoint + 200 would equal 1. x - 1 is -1. And this becomes true because of -π causing an even function within the points to occur in fact of negatives which are going to be resulted in by pi being -1 - 1 - 2 - 3. This other sign that -π - π(0) is zero at multiple different [soft] points of pi alone, and 0 - 2 would represent only negative 2. Getting to the point(I know this may have sounded very confusing, apologies.) there is one option that gives you the zero at point X assuming point X is also part of the origin, and that would make this point become option A.

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
