Answer:
The answer is y=7.5x and y=5.5x+10
Answer:
The measure of the third angle is 117 degrees and the measure of the two equal angles is 31.5 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A geodesic dome is compromised of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of the third angle is 85.5 degrees more than the measure of either of the two equal angles. Find the measure of the three angles
we know that
An isosceles triangle has two sides and two equal interior angles
Let
x -----> the measure of the third angle
y ----> the measure of either of the two equal angles
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
therefore
The measure of the third angle is 117 degrees and the measure of either of the two equal angles is 31.5 degrees
Answer:
<h2>It is Random sampling.</h2>
Step-by-step explanation:
There are total 5 types of sampling.
- Random Sampling: In this kind of sampling, elements are randomly chosen from a particular population. Every elements of the population carries the same probability in this case.
- Systematic Sampling: Every k-Th element is taken for this kind of sampling.
- Convenience Sampling: Here samples are chosen as per the accessibility.
- Cluster Sampling: First the whole population is divided in some groups or cluster, then some groups are randomly selected.
- Stratified Sampling: The whole population is being divided into groups as per some characteristic. Then from each group, one sample is to be chosen either randomly or using some other process.
Since, in the given question the students are chosen randomly, Random sampling is being used here.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
a = <em>b</em>
b = 14
c = 23
<u>Step 2: Find </u><em><u>b</u></em>
- Substitute [PT]: b² + 14² = 23²
- Isolate <em>b </em>term: b² = 23² - 14²
- Exponents: b² = 529 - 196
- Subtract: b² = 333
- Isolate <em>b</em>: b = 3√37
Answer:
The answers are 1, 4, and 6
Step-by-step explanation:
The answers are 1, 4, and 6 because
1. C(number of students that paid to attend) which was 124.
4. If you divide 558 from 124 it is generated the cost to be averaged at 4.50
6. The number is equaled to 558 so that is the event generated from student revenue.
