Answer:
For a triangle to be equiangular all its three interior angles must be equal, that is, each angle should measure 60˚.
Step-by-step explanation:
A should be the right answer. Hope this helped!
Answer: F (cos(230)).
Explanation:
Cosine corresponds to the x coordinate of points on a circle when the radius is drawn in like this, so the answer would be the cos of that angle, but you have to account for the fact that the 50 degree angle marked is just the reference angle not the entire angle so you have to add 180 degrees to that to get 230.
Así, concluimos que la posición final del buzo será 7 metros bajo la superficie del agua.
<h3 /><h3>¿a qué profundidad se encuentra al final de su recorrido?</h3>
Primero, vamos a definir la superficie del agua como el 0 metros.
Sí sabemos que primero el buzo se sumerge 4 metros, entonces en este punto la posición del buzo es:
P = 0m - 4m = -4m
Luego el buzo sube 2 metros, entonces la nueva posición será:
P = -4m + 2m = -2m
Finalmente, el buzo desciende otros 5 metros, entonces la posición final del buzo será:
P = -2m - 5m = -7m
Así, concluimos que la posición final del buzo será 7 metros bajo la superficie del agua.

To solve for proportion we make use of the z statistic.
The procedure is to solve for the value of the z score and then locate for the
proportion using the standard distribution tables. The formula for z score is:
z = (X – μ) / σ
where X is the sample value, μ is the mean value and σ is
the standard deviation
when X = 70
z1 = (70 – 100) / 15 = -2
Using the standard distribution tables, proportion is P1
= 0.0228
when X = 130
z2 = (130 – 100) /15 = 2
Using the standard distribution tables, proportion is P2
= 0.9772
Therefore the proportion between X of 70 and 130 is:
P (70<X<130) = P2 – P1
P (70<X<130) = 0.9772 - 0.0228
P (70<X<130) = 0.9544
Therefore 0.9544 or 95.44% of the test takers scored
between 70 and 130.
