Several trials are performed with the results shown in the table. What is the experimental probability of randomly drawing a green marble?

Red Blue Green
10 12 28
What is the experimental probability of randomly drawing a green marble?
What is the theoretical probability of randomly drawing a green marble?
What would you expect to happen if more trials of the experiment are performed? Explain your reasoning using complete sentences.

Answers

Answer 1

Answer:

experimental

[tex]p(green \: mable) = ( \frac{5}{24} \times \frac{8}{24} \times \frac{11}{24} ) \\ = 0.03[/tex]

theoretical

[tex] p(green \: mable) = \frac{12}{25} \\ = 0.48[/tex]

Answers

Answer:

the answer is B (x and y have a weak, positive correlation)

Give the person above me brainlyest for helping!

Step-by-step explanation:

The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

What is Coefficient of Correlation?

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.

Here, given values of x and y

x   1    2    3   4   5    6

y   3   4    9   7    2    18

xy  3   8   27  28 10  108

x²   1   4    9    16   25   36

y²   9  16  81  49  4  324

∑x = 21,  ∑y = 43,  ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6

Now, Correlation between x and y

r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]

r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]

r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)

r = 261 / √ 105 X 1049

r = 261 / √110145

r = 261 / 331.88

r = 0.78

Thus, The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.

Answers

Answer:

5

Step-by-step explanation:

To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

Please help, and answer only if you have an answer.

Answers

Answer:

$268.38

Step-by-step explanation:

First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.

Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38

$268.38 is the correct answer

According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.

[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)

Whenever dividing fractions, remember this:

SAME, CHANGE, RECIPROCAL (FLIP)

KEEP THE FIRST FRACTION THE SAME

CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN

FLIP THE SECOND FRACTION

[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]

[tex]\frac{42}{6} =7[/tex]

I, therefore, believe Muna will have 7 pieces of string.
