Answer:

Step-by-step explanation:

They are adjacent angles.

Adjacent angles are right next to each, or side-by-side. Considered (by my math teacher) the next door neighbors.

Answer:

They are supplementary!

Explanation:

Not sure if this is the type of relationship you're after, but angles that add up to a flat line (or, 180 degrees) are known as supplementary.

If we wanted to create a new 90% confidence interval from a different sample for the proportion of those with a two on one date

slava [35]

Answer: 271

Step-by-step explanation:

The formula we use to find the sample size is given by :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

, where $z_{\alpha/2}$ is the two-tailed z-value for significance level of $(\alpha)$

p = prior estimation of the proportion

E = Margin of error.

If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes

$n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2$

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2$

Given : Margin of error : E= 0.05

Confidence level = 90%

Significance level $\alpha=1-0.90=0.10$

Using z-value table , Two-tailed z-value for significance level of $0.10$

$z_{\alpha/2}=1.645$

Then, the required sample size would be :

$n=0.25(\dfrac{1.645}{0.05})^2$

Simplify,

$n=270.6025\approx271$

Hence, the required minimum sample size =271

A trash can in the shape of a cylinder has a radius of 26 cm and a height of 39 cm. Which of the following is closest to the vol

My name is Ann [436]

Answer:

The volume of cylindrical trash is 82,782.96 cm³ .

Step-by-step explanation:

Given as :

The shape of the trash is cylinder

The radius of cylinder = r = 26 cm

The height of cylinder = h = 39 cm

Let The volume of cylindrical trash = v cm³

<u>Now, According to question</u>

volume = $\Pi \times radius^{2}\times height$

where $\pi$ = 3.14

So, v = 3.14 × r² × h

Or, v = 3.14 × (26)² × (39)

Or, v = 3.14 × 26,364

∴ v = 82,782.96 cm³

So, volume of cylindrical trash = v = 82,782.96 cm³

Hence, The volume of cylindrical trash is 82,782.96 cm³ . Answer

Multiple the number of pounds by ___ to find total cost

lesya692 [45]

Answer:

Step-by-step explanation:

The function is 4x.

For every pound you have, you will have 4 times that amount in total cost. This is because of the pattern being shown. Example: 3 × 4 = 12 6 × 4 = 24 9 × 4 = 36.. and it just goes on and on.
