Jo paints some tennis balls and puts them in a bag. She picks a ball at random from the bag and replaces it. She repeats this 60 times, and gets a ball not painted 50 times. Find the experimental probability of getting a painted ball from Jo's bag.

Answers

Answer 1
Answer:

Answer:

1/6

Step-by-step explanation:

An experimental probability is the number of times an event occurred when actually attempted.

So, if Jo does the experiment 60 times and receives 50 unpainted balls, then calculate how many painted balls she got:

60-50 = 10.

So, the probability of picking a painted ball = 10/60 = 1/6

Hope this helps

Answers

The correct answer is:

0.14.

Explanation:

We are asked "Given that Lorenzo paid more than $30 for a ticket, what is the probability that he purchased the ticket at the box office?"

Using the conditional relative frequency table, we start at the column "More than $30".  We then go to the row "Purchased at the Box Office."  The value in this cell is 0.14; this is the probability.
Given:
Lorenzo paid more than $30 for a ticket.
What is the probability that he purchased the ticket at the box office?
 
                                           More than $30
Purchased online                 0.86
Purchased at the 
Box Office                               0.14
Total                                         1.00

The probability is 0.14/1.00 or 0.14

Answers

We have to calculate the size of a buttonhole if we know that it needs to be the size of the button`s diameter. We know also a circumference of the button: C = 9.42 cm. Formula for calculating the circumference is: C = 2 * r * Pi = d * Pi. Pi is approximately 3.14. So 9.42 = d * 3.14; d = 9.42 : 3.14; d = 3 cm. Answer: The size of the buttonhole has to be 3 cm.

The sum of a number and 3 times the same number is 100. What is the number?

Equation:

Solution:

Answers

X + (3 × X) = 100

25 + (3 × 25) = 100
Let the number be x.

According to your question,

x + 3x = 100                                ( Equation)

thus, 4x = 100

Thus, x = 100/4 = 25

Thus, the number is 25                     (Solution)

What side do DEC and EDB have in common?

Answers

Answer:

DE is the common side in the two triangles


Explanation:

The side of the triangle is named based on its start and end points

A triangle is named based on its three vertices where each two vertices would join forming a side


For ΔDEC, the sides are:

DE, EC and DC


For ΔEDB, the sides are:

ED, DB and EB


By comparing the two triangles, we would find that DE is the common side in both triangles


Note: The visual illustration is in the attached image


Hope this helps :)
If this were an angle it would surely be side DE & ED because both sides of that certain angle contains both point D and point E. It would serve as the common sides of that angle. This one is not adjacent to each other but both share common sides and also not common vertex.

Find the measure of b.

Answers

Answer:

b = 80°

Step-by-step explanation:

The inscribed angle measuring 100°, is supplementary to the angle opposite it in the inscribed quadrilateral.

Thus, the angle is = 80°

Therefore, b + 80° = 180° (angle on a straight line = 180°).

Thus, b = 180° - 80° = 100°.

The measure of b is 80°.
