Answer:

actually no.

Step-by-step explanation:

I assume you know the 4 inequalites:

The 4 Inequalities

Symbol Words Example

> greater than x+3 > 2

< less than 7x < 28

≥ greater than or equal to 5 ≥ x−1

≤ less than or equal to 2y+1 ≤ 7

The "open circle" represents less than or greater than, and the "closed circle" represents greater than or equal to or less than or equal to.

How would you find an interquartile range with just numbers?

Stolb23 [73]

Answer:

IQR is 3.5

Step-by-step explanation:

Step 1: Organize the numbers in numerical order

0,0,2,2,3,4,6,8

Step 2: Break the set up into quartiles (4 parts)

0 0 | 2 2 | 3 4 | 6 8

Step 3: Find the average of each quartile

0 | 2 | 3.5 | 7

Step 4: Find the IQR (Q3-Q1)

3.5-0=3.5

Therefore, the IQR is 3.5

Use the given data to find the minimum sample size required to estimate the population proportion. margin of error: 0.0080.008

nadezda [96]

Formula for the Minimum Sample size $n=(\frac{z}{E})^2\hat{p}\hat{q}$

The least biased estimate for p and q is 1/2.

$z_{\frac{\alpha }{2}}=z_{{0.01}{2}}=2.58$

Thus

$n=(\frac{2.58}{0.08})^2*0.5*0.5$

$n=260.015$

$n\approx260$

Please help me with this question

san4es73 [151]

Step-by-step explanation:

Given: $f'(x) = x^2e^{2x^3}$ and $f(0) = 0$

We can solve for f(x) by writing

$\displaystyle f(x) = \int f'(x)dx=\int x^2e^{2x^3}dx$

Let $u = 2x^3$

$\:\:\:\:du=6x^2dx$

Then

$\displaystyle f(x) = \int x^2e^{2x^3}dx = \dfrac{1}{6}\int e^u du$

$\displaystyle \:\:\:\:\:\:\:=\frac{1}{6}e^{2x^3} + k$

We know that f(0) = 0 so we can find the value for k:

$f(0) = \frac{1}{6}(1) + k \Rightarrow k = -\frac{1}{6}$

Therefore,

$\displaystyle f(x) = \frac{1}{6} \left(e^{2x^3} - 1 \right)$
