Answer:

B

Step-by-step explanation:

There are many ways to solve this, but the easiest is by noting the first and last points on the plot. These represent the minimum and maximum of the data set, respectively. This means the lowest point is 2, and the highest is 13. So, to find the correct set, just find the corresponding points. In this case, the only set that fits is the second one.

Equations and inequalities!<br> solve for w <br> 11=253-w

Annette [7]

Answer:

w = 242

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$11=-w + 253$
$-w + 253 = 11$

Step 2: Subtract 253 from both sides.

$-w + 253 - 253 = 11 - 253$
$-w = -242$

Step 3: Divide both sides by -1.

$\frac{-w}{-1}=\frac{-242}{-1}$
$w = 242$

Step 4: Check if solution is correct.

$11 = 253 - (242)$
$11 = 253 - 242$
$11 = 11$

Therefore, w = 242.

Have a lovely rest of your day/night.

Evaluate the indefinite integral. <br> integar x4/1 + x^10 dx

ivann1987 [24]

Answer:

$\int\ {\frac{x^4}{1 + x^{10}}} \, dx = \frac{1}{5}( \arctan(x^5)) + c$

Step-by-step explanation:

Given

$\int\ {\frac{x^4}{1 + x^{10}}} \, dx$

Required

Integrate

We have:

$\int\ {\frac{x^4}{1 + x^{10}}} \, dx$

Let

$u = x^5$

Differentiate

$\frac{du}{dx} = 5x^4$

Make dx the subject

$dx = \frac{du}{5x^4}$

So, we have:

$\int\ {\frac{x^4}{1 + x^{10}}} \, dx$

$\int\ {\frac{x^4}{1 + x^{10}}} \, \frac{du}{5x^4}$

$\frac{1}{5} \int\ {\frac{1}{1 + x^{10}}} \, du$

Express x^(10) as x^(5*2)

$\frac{1}{5} \int\ {\frac{1}{1 + x^{5*2}}} \, du$

Rewrite as:

$\frac{1}{5} \int\ {\frac{1}{1 + x^{5)^2}}} \, du$

Recall that: $u = x^5$

$\frac{1}{5} \int\ {\frac{1}{1 + u^2}}} \, du$

Integrate

$\frac{1}{5} * \arctan(u) + c$

Substitute: $u = x^5$

$\frac{1}{5} * \arctan(x^5) + c$

Hence:

$\int\ {\frac{x^4}{1 + x^{10}}} \, dx = \frac{1}{5}( \arctan(x^5)) + c$
