Answer:

The probability model is

= P(A or B)

Step-by-step explanation:

a) Data and Calculations:

Estimated revenue if the day is sunny = $3,000

Estimated loss if the day is rainy = $600

The probability of rain = 30%

Therefore, the probability of sunshine = 70% (100 - 30)

The probability model is based on the probability of rain or sunshine

= P(A or B)

= A*70% - B*30%

The outcome from either rain or sunshine

= ($3,000 * 70%)  -($600 * 30%)

= $2,100 - $180

= $1,920

Answer:

Circumference of Circle B=19.625cm

Step-by-step explanation:

The circumference formula is: 2pie(r) = pie(d)

We have diameter of the first circle which is 6. Now, because the diameter of second circle is 25% greater than this,

Hence, we add 25% in 6:

6+25/100 =6+0.25=6.25 cm

Therefore, we have diameter of 6.25 for circle B.

Now, we need to find the circumference of the Circle A.

circumference= pie(d) = pie(6)= 3.14times6= 18.84

Now use the proportional reasoning to find Circumference of Circle B:

circumference of Circle A/diameter Circle A = circumference of Circle B/diameter Circle B

18.84/6=circumference of Circle B/6.25

Cross multiply and divide:

(18.84times6.25)/6 = Circumference of Circle B

Solve:

Circumference of Circle B=19.625cm

Hope this helps!
