10 > X - 3. Help please

amm1812

Answer:

x<13

Step-by-step explanation:

1. Move variable [x] to left-hand side and change its sign

Move constant [10] to the right-hand side and change its sign

10>x-3

-x+10>-3-10

2. Calculate the difference [-3-10]

-x>-3-10

-x>-13

3. Change the signs [-x>-13] on both sides of the inequality and flip the inequality sign

x<13

4. Solution

x<13

Make r the subject of the formula v = \pi \: h {}^{2}(r - \frac{h}{3})v=πh2(r−3h)

mel-nik [20]

Answer:

$\boxed{r = \frac{h}{3} + \frac{v}{\pi {h}^{2} } }$

Step-by-step explanation:

$Solve \: for \: r: \\ = > v= \pi {h}^{2}(r - \frac{h}{3} ) \\ \\ v=\pi {h}^{2}(r - \frac{h}{3} )is \: equivalent \: to \: {h}^{2}\pi(r - \frac{h}{3} ) = v: \\ = > {h}^{2}\pi(r - \frac{h}{3} ) = v \\ \\ Divide \: both \: sides \: by \: \pi {h}^{2} : \\ = > r - \frac{h}{3} = \frac{v}{\pi {h}^{2} } \\ \\ Add \: \frac{h}{3} \: to \: both \: sides: \\ = > r = \frac{h}{3} + \frac{v}{\pi {h}^{2} }$

Suppose that the p-value was 0.0259. what is the appropriate conclusion to make if α = 0.05?

fiasKO [112]

It is clear to see that 0.0259 is less than 0.05. A p-value that is less than the confidence level of alpha indicates that there is sufficient evidence from the data that the null hypothesis should be rejected in favor of an alternative hypothesis.

What is the slope of (-1,2) and (0,-4)

Serga [27]

Answer:

- 6

Step-by-step explanation:

$slope = \frac{ - 4 - 2}{0 - ( - 1)} = \frac{ - 6}{0 + 1} = \frac{ - 6}{ 1} = - 6 \\$
