If a point at random, what is the probability that it will be in the shaded section. Give your answer as a fraction or a percentage to the hundredths

Answers

The diagram isn't attached. However, a rated diagram has been found and attached below.

Answer:

0.8611

Step-by-step explanation:

The probability of an event involves taking the ratio of the required measurement and the entire measurement.

Based on information on the attached circle, the shaded region of the circle takes 310° of the entire 360°

Choosing a point at random from which nside the circle ;

P(shaded portion) = shaded section / total measure of circle

P(shaded point) = 310 / 360 = 0.8611

Choose the mixed number that is equivalent to $ 1.32.​

1 32 /100

3 12/100

1 32/10

32/100

Answers

Answer:

1.32/100

Step-by-step explanation:

Address input parameters and values. Input parameters and values: The decimal number = 1.32Write it as a fraction ; 1.32/1Multiply 100 to both numerator and denominator

(1.32×100)/(1×100) = 132/100

It can be written as 132%= 132/100 or 132/100

4. To simplify 132/100 to its lowest terms, find LCM for the 132 and 100

4 is LCM for 132 and 100.

5. Divide numerator and denominator by 4

132/100=(132/4)/(100/4)=33/25.

33/25 is a simplest fraction for the decimal point number 1.32.

Answer:

132/100

Step-by-step explanation:

When you multiply by 10,100,1000.... you add zero. For example:132×10=1320 132×100=13200When you devide by 10,100,1000 you decrease the number starting from the right to left. For example: 132/10=13,2 132/100=1,32. NOTE it depends on the number of zeros.

(no multiple choice)

Answers

Answer:

Step-by-step explanation:

Initial number = 6500Growth rate = 3.5% = 0.035 timesFinal number = 11500Time t = ?

Formula:

P(t) = 6500(1 + 0.035)^t

Solve for t:

11500 = 6500*1.035^t11500/6500 = 1.035^tlog 1.7692 = log 1.035^tt = log 1.7692 / log 1.035t = 16.6 (rounded)
