Y=5

Step By Step:
180-75-75
30
4y+10=30
4y=20
y=5

Since this is an isosceles, you know that angle B is congruent to angle C (they’re both 75°).

Answer:

y = 5

Step-by-step explanation:

ok so we dont really need to know what x is unless they ask for it but ill do it anyways

B angle and C angle are equal so...

B = 75

75 = (3x)

75 / 3 = 25

x = 25

a triangles angles equals 180 degrees

75 + 75 = 150

180 = 150 + ?

180 - 150 = 30

A = 30 degrees

4y + 10 = 30

get the y on it's own side

4y + 10 - 10 = 4y

30 - 10 = 20

4y = 20

4y / 4 = y

20 / 4 = 5

y = 5

An urn contains 5 are red balls and 6 blue balls. Suppose 5 are randomly selected without replacement. What is the probability t
Viefleur [7K]

Answer:

27.94%

Step-by-step explanation:

The statement tells us that we have 5 red balls and 6 blue balls, that is, there are 11 in total (5 + 6)

So the probability of red balls = 5/11 and blue balls probability = 6/11

Let X be the number of red balls of those 5 selected balls.

 Then X follows a binomial distribution with the following parameters:

n = 5

p = 5/11

q = 6/11

P (X) = nCx * p ^ (x) * q ^ (n -x)

required probability is P (X = 3), replacing:

P (X = 3) = 5C3 * (5/11) ^ (3) * (6/11) ^ (5 -3)

P (X = 3) = 5! / (3! (5-3)!) * 0.02794

P (X = 3) = 10 * 0.02794

P (X = 3) = 0.2794

Which means that the probability is 27.94%

Find the angular displacement of 1.9 revolutions. Use π=3.14 . Round the answer to the nearest tenth.
Elena-2011 [213]
To answer the question above, convert the given displacement in revolutions to radians. The conversion factor is 1 revolution is equal to 6.28 radians.  

             (1.9 rev) x (6.28 radians / 1 rev) = 11.932 radians

Thus, the closest to this value is 11.9 and the answer is the second choice.
