A study reported that about half of young adults continue to text and drive, despite the dangers. To find out if this applies to teens, you asked an SRS of 30 classmates if they texted while driving, and 13 responded "Yes.” To see if this result is surprising, you need to conduct a simulation to estimate the probability of obtaining a sample result as low as yours given that the young adult study is correct. Which is a correct method to model expected results based on the study’s claim? Using a coin, let heads = yes and tails = no; flip the coin 30 times, recording the proportion of heads; and perform many trials.
Using a die, let evens = yes and odds = no; roll the die 30 times, recording the proportion of times evens occur; and perform many trials.
Using a die, let 1–2 = yes and 3–6 = no; roll the die 30 times, recording the proportion of times 1–2 occur; and perform many trials.
Using a die, let 1–3 = yes and 4–6 = no; roll die 30 times, recording the proportion of times 1–3 occur; and perform many trials.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
