The probability to choose letter n is
. After drawing letter n there left 25 letters and the probability to choose the letter w is
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is
.
Using the product rule for probabilities, you can obtain that
.
150=i^2
150^.5=12.2474
11^2=121
12^2=144
13^2=169
between 12 and 13, D
If D is the midpoint of CE, then CD must be equal to DE
Answer: C
Check the picture below.
that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.
anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.
there are some online regression calculators as well.
Answer:
hence the value of y is 19°
Step-by-step explanation:
y+125+36=180(sum of inside the triangle is 180°)
y+161=180
y=180-161
y=19°
