1. If you're looking for a one-dimensional answer, then the answer would be a triangle (if you're looking at the surface of the cut). The three sides would be the diameter and the slant heights.
2. Again, if you're looking for a one-dimensional answer, the answer would be a rectangle. The four sides would be the diagonals and the heights.
Hope this helps and sorry I couldn't reply sooner!
Answer:
B
Step-by-step explanation:
In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:
Now we just need to solve for b:
and
so
Will all i see is this = <span>4x16=643x24=7264+72
=136136-15=121

3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
The confidence interval would be (0.122, 0.278).
We first find our z-score. We want a 95% confidence interval:
0.95/2 = 0.475
Looking this up in the z-table, (http://www.statisticshowto.com/tables/z-table/) we see the z-score is 1.96.
The formula we will use is:
In this problem, p = 20/100 = 0.2, and n=100:
