Answer:

32.54%

Step-by-step explanation:

To determine the probability that an individual song has a danceability of at least 0.7

Applying the excel formula below

=COUNTIF ( I2:I4771,">0.7") / ROWS( I2:I4771)

Hence ; The probability of an individual song having a danceability of at least 0.7 = 32,54%

Find the average value of the function over the given solid. The average value of a continuous function f(x, y, z) over a solid

ratelena [41]

Compute the volume of $Q$ :

$\displaystyle\iiint_Q\mathrm dV=\int_0^2\int_0^{2-x}\int_0^{2-x-y}\mathrm dz\,\mathrm dy\,\mathrm dx=\frac43$

Integrate $f(x,y,z)=x+y+z$ over $Q$ :

$\displaystyle\iiint_Qf(x,y,z)\,\mathrm dV=\int_0^2\int_0^{2-x}\int_0^{2-x-y}(x+y+z)\,\mathrm dz\,\mathrm dy\,\mathrm dx=2$

So the average value of $f$ over $Q$ is 2/(4/3) = 3/2.

Given the function, g(x) = 2x2 − 16x + 15 ,how do i find the axis of symmetry?

hichkok12 [17]

You can factorise the function to get 2 (x^2 - 8x + 7.5) and then complete the square to get 2(x - 4)^2 - 17. Because this shows that the graph has been moved 4 units to the right, the axis of symmetry is x=4.

How many ways can 10 students be seated in a room with 13 chairs?

rewona [7]

Use combination to solve it
13C10 = $\dfrac{13!}{10! \times (13-10)!}$
13C10 = $\dfrac{13 \times 12 \times 11 \times 10!}{10! \times 3!}$
13C10 = $\dfrac{13 \times 12 \times 11}{3!}$
13C10 = $\dfrac{13 \times 12 \times 11}{3 \times 2 \times 1}$
13C10 = $\dfrac{1716}{6}$
13C10 = 286
There are 286 ways
