So we are given the probabilities of q and r:

p (q) = 0.12

p (r) = 0.25

p (q and r) = 0.03

 

Actually to find for p (q or r), this simply means to add all the values of p (q). p (r) and p (q and r). If we are to draw a bubble diagram, the p (q and r) is the bubble intersection p (q) and p (r). We know that the word “OR” takes up all in the bubble diagram. Therefore:

p (q or r) = p (q) + p (r) + p (q and r)

 

Substituting the given values into the equation:

p (q or r) = 0.12 + 0.25 + 0.03

Answer:

0.34

Step-by-step explanation:

The probability of A or B occurring if they are not mutually exclusive is given by

P(A)+P(B)-P(A and B)

In this case, we have

P(q)+P(r)-P(q and r)

= 0.12+0.25-0.03 = 0.34

Answer:

fff

Step-by-step explanation:

By pythagorean theorum we calculate the height:

\sqrt{5^2-1^2}

=\sqrt{24} = height of triangle

area of triangle = base * height

area = 2*\sqrt{24}

There are two triangles so:

2*2*\sqrt{24}=4\sqrt{24}

Multiply this by 13.25 to get total cost:

=$259.65

Rachel traveled to five different areas (A, B, C, D, and E) to study the number of buckeye butterflies and the number of monarch
Ivenika [448]

Answer:

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion

Step-by-step explanation:

Given that

Rachel traveled to 5 areas to find  number of Buckeye and Monarch butterflies.

Areas Rachel Traveled to = A, B, C, D, E

The table given below shows her findings.

Area            Buckeye          Monarch

A                     15              16  

B                      27              36  

C                     12              25  

D                      24              32  

E                      44              33

Now lets find the ratio of Buckeye and Monarch Butterflies in these areas

Area A

Buckeye : Monarch = 15:16 = 0.9375

Area B

Buckeye : Monarch = 27:36 = 0.75

Area C

Buckeye : Monarch = 12:25= 0.48

Area D

Buckeye : Monarch = 24:32 = 0.75

Area E

Buckeye : Monarch = 44:33 = 1.334

As we know that if two ratios give same answer after solving the fraction then these ratios are in proportion.

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion.
