Answer:

x = 6

Step-by-step explanation:

The area of a triangle is equal to the base times the height divided by two. In this case, the base is 6 (or x, it doesn't really matter) and the height is x (or 6, it doesn't matter). That means that the area of this triangle is equal to 6 * x divided by 2, which is also equal to 18. we can say that 6x/2 = 18, meaning that 6x = 36, so x = 6.

5 units over
with a scale factor of .5

What this is asking is how do you turn the one shape into the other. The first answer is how many spaces apart they are. In this case the smaller rectangle EHGF was 5 units (or squares over... Also note that the fact that the larger rectangle is higher doesn't matter because the space is reduced when it is shrunk). The second answer was talking about how much smaller it was. This is identified by counting the sides. rectangle EHGF had sides 1 unit (square) and 2.5 units (squares) long this is half or .5 of the larger ABCD's 2 units (squares) and 5 units (squares).

Answer:

The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

In 2017, a random sample of 154 individuals who graduated from high school 12 months prior was selected. From this sample, 94 students were found to be enrolled in college or a trade school.

This means that $n = 154, \pi = \frac{94}{154} = 0.6104$
