Answer:

Vertical

Step-by-step explanation:

We can see that the line is parallel to the y-axis. This is an indicator that the line is vertical.

On the other hand, if the line was parallel to the x=axis, it would indicate that it is horizontal.

I hope this helps!

The volume of a right square pyramid is 300 cubic units. If the area of the base is 50 square units, what is the height of the p

tresset_1 [31]

Answer: 18

Step-by-step explanation:

formula for volume of right square pyramid- area of the base * h/3 = volume

so, volume/ area of the base = 1/3 of height

300/50= 6. multiply your answer by 3 to get the full hight. 6*3= 18

your answer is 18 :)

How much would d dollars earn in one year at the rate of p percent compounded annually

Elenna [48]

Answer:

Step-by-step explanation:

Adapt the compound amount formula to this situation:

A = P(1 + r)^t becomes A = d(1 + p/100)^1, or just A = d(1 + p/100)

What should a size of a sample be in order to have a margin of error of 4% for a 90% confidence level from a population with a s

vagabundo [1.1K]

Answer:

We need a sample size of 2,071,800 or higher.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.9}{2} = 0.05$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.05 = 0.95$ , so $z = 1.645$

Now, we find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

In this problem:

We need a sample size of n or higher, when $M = 0.04, \sigma = 35$ . So

$M = z*\frac{\sigma}{\sqrt{n}}$

$0.04 = 1.645*\frac{35}{\sqrt{n}}$

$0.04\sqrt{n} = 1.645*35$

$0.04\sqrt{n} = 57.575$

$\sqrt{n} = 1439.375$

$\sqrt{n}^{2} = (1439.375)^{2}$

$n = 2,071,800$

We need a sample size of 2,071,800 or higher.
