Between which two consecutive whole numbers does the value of √389 lie?​

The perimeter of ΔMNP is calculated as; 130

From the given image, it is clear that some sides are congruent to others as indicated.

Thus, we see the following;

QM is parallel and congruent to RS.

Similarly, we see that QR is parallel and congruent to MS.

PR is parallel and congruent to QS.

NR = PR because of line segment division.

Thus, we can plug in the relevant values to get;

PR = QS = 22 = NR

Similarly, MS = SP = QR = 25

RS = x + 4 and so;

x + 4 + x + 4 = 5x - 34

42 = 3x

x = 14

MN = 5(14) - 34

MN = 36

Thus, the perimeter of ΔMNP = 36 + 25 + 25 + 22 + 22

= 130

Answer:

P (n,r)

Step-by-step explanation:

The correct representation for a permutation is P (n,r).

The percentage of miles the car has left in battery charge is 10.77%

Total distance traveled when fully charged = 260 miles

The total charged used by the car = 232 miles of charges

The remaining charges left in the car battery = Total distance traveled when fully charged - The total charged used by the car

Here we have to use the subtraction

Substitute the values in the equation

= 260 - 232

= 28 miles of charges

The percentage of miles the car has left in battery charge = (28/260) × 100

= 10.77%

Therefore, 10.77% miles of charge left in the battery

The answer is (10) 8' and (3) 12 A

Step-by-step explanation:

To build a wall that is 12' long and 8' high, you will need (10) 8' 2x4's and (3) 12' 2x4's. This will give you the necessary length for the bottom and top plates and 10 studs. Each stud should be spaced about 16" on center, so 10 studs will be enough to support the wall.

As calculated from the data (1/6)² is the probability of getting 5 of same number on all the dice.

b.)If we will limit the number of winners then we will be able to provide them with large prizes and that also by taking moderate rate from everyone.

Actually, the likelihood of winning is closer to one-third (25/72).

Carnival game organizers want you to believe, like I did, that a game is fair so that you will participate.

The likelihood that you would win a game was just about 1/3, so you probably wouldn't squander your money.

Therefore,

The likelihood of getting five of the same number on all six dice is (1/6)².

Probabilities are mathematical representations of the likelihood that an event will occur or that a statement is true.

Probability can also be expressed using a tree diagram.

The tree diagram makes it easier to organize and see all of the potential outcomes. The tree's branches and ends are its two primary locations. On each branch is written the probability, and the ends hold the results in the end.

For automobile traffic, dB=81.987657 dB.

For quiet conversation is 40.33423 dB.

For fender guitar, 115.56302 dB.

For jet engine, 151.98657 dB.

(A)

The intensity of automobile traffic is, I=1.58x10^8 I.

Given: dB=10 log (I/I0)

Substituting the value of I,

dB= 10 log (1.58x10^8 I/I)

=10 log (1.58x10^8)

Using the logarithm property,

=10 (log (1.58)+log (10^8))

=10 (log (1.58)+8 log (10)

=10( log (1.58)+8(1)

=80+1.98657

=81.98657

Thus, for automobile traffic, dB=81.987657 dB.

B)

Quiet conversation, I=10800 I0

dB= 10 log (10800 I0/I0)

=10 log (10800)

=10 log (1.08x10^4)

=10 log (1.08)+log (10^4)

=10 (log (108)+4log (10))

=10 (log (1.08+4*(1))

=40+10 log (1.08)

=40+0.33423

=40.33423 dB.

Thus, for quiet conversation is 40.33423 dB.

C)

Fender guitar, I=3.16x10^11 I0

dB= 10 log (3.16x10^11 I0/I0)

=10 (log (3.16)+11)

=110+10 log (3.16)

=110+5.56302

=115.56302

Thus, for fender guitar, 115.56302 dB.

D)

Jet engine, I=1.58x10^5 I0

dB= 10 log (1.58x10^15 I0/I0)

=10 (log (1.58)+15)

=150+10 log (1.58)

Answer:

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

Step-by-step explanation:

To determine who wins the race, we need to first convert the given information into comparable units. The speed of Adil is given in kilometers per hour, while the time taken by Tom to complete the race is given in seconds. We can convert Adil's speed to meters per second by dividing by 3.6:

28.8 km/hr = 28.8 km/hr * (1 hour / 3600 seconds) * (1000 meters / 1 km)

         = 8 meters/second

We can then use this value to find the time it takes Adil to complete the race:

time = distance / speed

   = 200 meters / 8 meters/second

   = 25 seconds

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

The area would be

100x 60 = 6,000 [tex]m^{2}[/tex]

If we change the length and width to 80 meters we would have the same perimeter

Answer:

y = 3x + 37

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 13 ) and (x₂, y₂ ) = (- 6, 19 )

m = [tex]\frac{19-13}{-6-(-8)}[/tex] = [tex]\frac{6}{-6+8}[/tex] = [tex]\frac{6}{2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (- 8, 13 ) , then

13 = 3(- 8) + c = -24 + c ( add 24 to both sides )

37 = c

y = 3x + 37 ← equation of line

The true statements are

Consider the two points in the line

(-1, 1) and (3, 2)

The slope of the line = (2-1) / (3 -(-1))

= 1/4

The slope intercept form is

y = mx + b

2 = (1/4)3 + b

2 = 3/4 + b

b = 2 - (3/4)

b = 5/4

The equation of the line y = (1/4)x + 5/4

(3, 2) and (-1, 1) are points on the line

Consider the point (1, 3/2)

3/2 = (1/4)1 + 5/4

3/2 = 1/4 + 5/4

3/2 = 3/2

Moment generating function of a random variable is the expectation of a random variable. The moment generating function of the geometric(p) distribution is given by pe^{t}/ (1 - (1 - p)e^{t}.

A moment generating function can be described as

MGFₓ(t) = E( e^{tx})

For continuous x

E( e^{tx}) = ∫ₓ e^{tx}×f(x)×d(x) where f(x) is the probability density function.

For discrete x

E( e^{tx}) = ∑ₓ e^{tx}×P(x) where P(x) is the probability mass function.

A geometric distribution is a discrete probability distribution that provide us the probability that the 1st occurrence o success would need k independent trials of success probability p each. Thus probability mass function of geometric distribution is

P(X = k) = (1 - p)^{k} × p

So moment generating function can be obtained by

MGFₓ(t) = E( e^{tx}) = ∑ₓ e^{tx}×P(x)

MGFₓ(t) = ∑ₓ (e^{kt} × (1 - p)^{k} × p)

MGFₓ(t) = p×∑ₓ (e^{t} × (1 - p))^{k}

|e^{t} × (1 - p)| < 1 so applying property of sum of infinite geometric progression we have

MGFₓ(t) = p× e^{t}/ (1 - (1 - p)e^{t}

Answer: Luisa is correct.

Step-by-step explanation: Luisa is correct. To find the solution to the equation, we need to isolate the radical expression on one side of the equation. If we subtract x from both sides, we get √5 + 4x - x = x - x, or √5 = 0. Since the square root of any number is always positive, this equation has no solution. Therefore, the solution is H = 5.

On the other hand, if we square both sides of the equation, we get 5 + 8x + 4x^2 = x^2. If we simplify this equation, we get x^2 + 8x - 5 = 0. This equation can be solved using the quadratic formula, which gives us x = (-8 +/- sqrt(64 + 20))/2. This simplifies to x = (-8 +/- sqrt(84))/2. The solutions to this equation are x = -1 and x = 5. However, since we squared both sides of the original equation, we have to check whether these solutions actually work in the original equation. Substituting x = -1 into the original equation gives us √5 + 4(-1) = -1, or √5 = -1. This is not a valid solution, since the square root of any number is always positive. However, substituting x = 5 into the original equation gives us √5 + 4(5) = 5, or √5 = 0. This is a valid solution, since the square root of any number is always positive. Therefore, the only solution to the original equation is x = 5, which is the solution that Luisa found.
