What is x divided by 3?

Answer:

the first  is 2 inches the 2nd one 4 inches and the 3rd is 8 inches

Step-by-step explanation:

The length of the piece is 2, 4 and 8.

Two or more expressions with an Equal sign is called as Equation.

Given that a 14 inch board is to be cut into three pieces

Let first piece be x.

The second piece is twice as long as the first piece

Second piece is 2x

The third piece is 4 times as long as the first piece.

Third piece is 4x

x+2x+4x=14

7x=14

Divide both sides by 7

x=2

Hence, the length of the piece is 2, 4 and 8.

Answer:

x=34

Step-by-step explanation:

Use pythaogrean therom to find the answer. a^2+b^2=c^2 With that in mind, the answer 16^2+30^2=1156. To get the exact answer, you'll have to square root the 1156 to get 34. If you want to check you answer, take the 34 and square it then subtract it by one of the numbers it gives you.

Answer:

y = -3x + 17/10

Step-by-step explanation:

First you want to move the 2x to the other side of the equal sign for the proper way of slope-intercept form. Which makes it 6y=2x-8.

You still want to make sure that y is by itself so you divide the whole equation by 6 which makes it y=1/3x-8/6.

We have to find the slope of the a perpendicular line now and to do so, you must take the slope of the given line and make it into the opposite reciprocal.

To do that you take 1/3 and reciprocate it, which makes it 3.

Then flip the sign to make it opposite. Like making a positive into a negative and a negative into a positive. Therefore the slope of the perpendicular line is -3.

Now we must make it past through point (-2,1). To do that you have to adjust the y-intercept. Because of that, the y-intercept is 1.7 or 17/10.

The equation of the slope is y=-3x+17/10

Answer:

The probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.

Step-by-step explanation:

The random variable X can be defined as the number of incoming phone calls during the noon hour on Thursdays.

The random variable X describes a finite number of occurrences of an event in a fixed time interval.

The random variable X follows a Poisson distribution with parameter λ = 8.2.

The probability mass function of X is:

[tex]P(X=x)=\frac{e^{-8.2}(8.2)^{x}}{x!};x=0,1,2,3...[/tex]

Compute the probability of more than 4 calls as follows:    

[tex]P(X>4)=1-P(X\leq 4)[/tex]

                [tex]=1-\sum\limits^{4}_{x=0}{\frac{e^{-8.2}(8.2)^{x}}{x!}}\\\\=1-[0.00027+0.00225+0.00923+0.02524+0.05174]\\\\=1-0.08873\\\\=0.91127\\\\\approx 0.9113[/tex]

Thus, the probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.

Answer:

78.125 ft²

Step-by-step explanation:

The dimension of the tablet is given as:

Length = 1 in

Width = ½ in

First,we need to determine the measurements in feet.

Using the scale measurement:

Scale: 2 in =25 ft

Divide both sides by 2

2 in/2 = 25 ft/2

1 in = 12.5 ft

So, Length = 12.5 ft

Divide the scale measurement by 4

2 in/4 = 25 ft/4

½ in = 6.25 ft

So,

Width = 6.25 ft

Area is calculated as:

Area = Length * Width

Area = 12.5 ft * 6.25 ft

Area = 75.125 ft²

Answer:

The  probability distribution of x is  

     Profits in millions (x)                            Probability of getting contract (P(x))

          $10                                                                   0.15

          $ 5                                                                    0.30

          $ 2                                                                    0.45

          $ 0                                                                    0.10

The  mean is  [tex]E(X) = 3.9 millions  [/tex]

The  standard deviation is  [tex]s = 3.01 \  millons   [/tex]

Step-by-step explanation:

Generally the probability distribution of  x is

 Profits in millions (x)                            Probability of getting contract (P(x))

          $10                                                                   0.15

          $ 5                                                                    0.30

          $ 2                                                                    0.45

          $ 0                                                                    0.10

Generally the mean is mathematically represented as

     [tex]E(X) =  x  *  p(x)[/tex]

=>    [tex]E(X) =  [10 *  0.15 ]  +  [5 *0.30 ] + [2 *  0.45 ] + [0 * 0.10] [/tex]

=>    [tex]E(X) = 3.9 millions  [/tex]

Now

      [tex] E(X^2) =  x^2 * p(x)[/tex]

=>   [tex] E(X^2) =  (10 ^2 *   0.15) +  (5  ^2 *   0.30) +(2  ^2 *   0.45) + (0 * 0.10)[/tex]

=>   [tex] E(X^2) = 24.3 [/tex]

Gnerally the variance is mathematically represented as

        [tex]V(X) =  E(X^2) - [E(X)]^2[/tex]

=>      [tex]V(X) =  24.3 -  3.9^2[/tex]

=>     [tex]V(X) =  9.09 [/tex]

Gnerally the standard deviation is mathematically represented as

    [tex]s =  \sqrt{V(X)}[/tex]

=>  [tex]s =  \sqrt{9.09[/tex]

=>  [tex]s = 3.01 [/tex]

Kindly check explanation

Step-by-step explanation:

Given the data below :

x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6

Mean(m) = ΣX / n

ΣX = 1066 ; n = number of observations = 18

Mean(m) = 1066 / 18

Mean = 59.22

Standard deviation (σ) :

Using the online standard deviation calculator :

σ = √(Σ(x - m)²/n-1)

σ = √264.198395

σ = 16.72

The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.

typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.

(59.22 - 19.7) mL = 39.52mL

Mean amount poured into a tall slender glass = 51.283

Mean (short wide glass) = 59.22mL

Mean (tall slender glass) = 51.283mL

Short wide glass > tall slender glass

Answer:

[tex]=256x^8y^{20}[/tex]

Step-by-step explanation:

We have the expression:

[tex](4x^2y^5)^4[/tex]

We can use the power of a product property:

[tex](ab)^x=a^xb^x[/tex]

This yields:

[tex]=(4)^4\cdot(x^2)^4\cdot(y^5)^4[/tex]

We can evaluate 4 to the fourth:

[tex]=256(x^2)^4\cdot(y^5)^4[/tex]

Now, we can use the power of a power property:

[tex](x^a)^b=x^{ab}[/tex]

So:

[tex]=256(x^{2(4)})(y^{5(4)})[/tex]

Multiply:

[tex]=256x^8y^{20}[/tex]

And we're done!

Answer:

256x^8 y^20

that's the answer I got when I simplified it
