To find the total number of butterflies we add 9 and 7, which equals 16 butterflies in all. Then we take the queen butterfly part of the ratio, which is 7 and compare it with the total number of butterflies to get the ratio 7:16.

How many different triangles can you make if you are given the measurements for two Angles and the length of a side that is not
nordsb [41]

Answer:

  c.  2

Step-by-step explanation:

Defining two angles of a triangle means you know the values of all of the angles. When all angles are known and the side opposite one of them is known, then the triangle is completely determined.

In this case, the angle opposite the given side can be either of the two given angles, so two triangles are possible.

__

If the two angles have the same measure, then only one triangle is possible.

The following table shows the probability distribution for a discrete random variable.
mezya [45]

Answer: C. 30.47

Step-by-step explanation:

The mean of discrete random variable i.e. the expected value of X is given by :-

E(X)=\sum^{i=n}_{i=1} X_iP(X_i)

Now by using the given table, the expected value of X is given by :-

\\\\\Rightarrow\ E(X)=23\cdot (0.16)+25\cdot(0.09)+26\cdot(0.18)+31\cdot(0.12)+34\cdot(0.24)+38\cdot(0.21)\\\\\Rightarrow\ E(X)=30.47

Hence, the  mean of discrete random variable= 30.47

Ashley, Milan, and Carlos sent a total of 131 text messages over their cell phones during the weekend. Carlos sent 7 times as ma
nordsb [41]

Answer:

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11
