It would be the first one because it’s the only one with the same numbers. if all the numbers and xy match then that mean there’s an infinite numbering solutions

Step-by-step explanation:
<u>Given equation:</u>
<u>Solve:</u>
Using the proportion concept, it is found that:
- According to Tyler's sample, the estimate is of 0.2 = 20%.
- According to Kyran's sample, the estimate is of 0.17 = 17%.
- Due to the higher sample size, Kyran's estimate is more accurate.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and larger sample sizes lead to more accurate predictions.
In Tyler's sample, 2 out of 10 students would dye their hair blue, hence:
p = 2/10 = 0.2.
In Kiran's sample, 17 out of 100 would, hence:
p = 17/100 = 0.17.
Due to the higher sample size, as 100 > 20, Kyran's estimate is more accurate.

Answer:
19.4 feet
Step-by-step explanation:
Since the triangle has a right angle( as one of the angles in it is equal to 90°), we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
Given that the measure of ∠G=90° and ∠E=40°
EF is the hypotenuse side
FG is the opposite side and
GE is the adjacent side. As such if EF = 75 feet
Cos 75 = GE/75
GE = 75 Cos 75°
= 19.41 feet
≈ 19.4 feet in the nearest tenth of a foot
