You select a marble without looking and then put it back. If you do this 60 times, what is the best prediction possible for the number of times you will pick a blue or a purple marble?
LOOK AT IMAGEEE
Based on the given information, where there are 7 blue marbles and 3 purple marbles, and assuming the selection process is random and each marble has an equal chance of being selected, the best prediction for the number of times you will pick a blue or a purple marble can be calculated as follows:
Out of the 60 selections, we can expect to pick a blue marble approximately 7/10 times (since there are 7 blue marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a blue marble is around 60 * (7/10) = 42 times.
Similarly, we can expect to pick a purple marble approximately 3/10 times (since there are 3 purple marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a purple marble is around 60 * (3/10) = 18 times.
Hence, the best prediction is that you will pick a blue marble around 42 times and a purple marble around 18 times out of the 60 selections.
~~~Harsha~~~
Answer:
18 times
Step-by-step explanation:
If there are 7 blue marbles and 3 purple marbles, the probability of selecting a blue marble is 7/10, and the probability of selecting a purple marble is 3/10.
Since you're selecting marbles without replacement, the probability will change with each pick. To calculate the best prediction for the number of times you will pick a blue or purple marble, we can multiply the probabilities by the number of picks.
Expected number of blue marbles picked: (7/10) * 60 = 42
Expected number of purple marbles picked: (3/10) * 60 = 18
Therefore, the best prediction is that you will pick a blue marble approximately 42 times and a purple marble approximately 18 times when selecting marbles without looking 60 times.
How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

A peregrine falcon can dive at the speed of 320km/h. Create a problem that you can solve by finding an equivalent rate for this speed. Then solve the problem.
Question: A peregrine falcon can dive at the speed of 320km/h. How many kilometres can the bird traveling in a minute?
Answer: 5 1/3 kilometres per minute
320 ÷ 60 would convert the hours to minutes and so you get 5 1/3 kilometres per minute (kpm).

Can you show more information please?
Answer:
Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :
y = 1.87x + 3.66
predicted amount of tip for 100 customers = $191
The predicted amount of tips received of 100 customers are served :
y = 1.87x + 3.66
x = 100 ; substitute x = 100 into the equation
y = 1.87(100) + 3.66
y = 187 + 3.66
y = 190.66
Hence, about $191 would be received on tips if 100 customers are recorded.
Using a regression calculator to make prediction from a data table :
Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer:
76°
Step-by-step explanation:
Use the Exterior Angle Property. The Exterior Angle Property states that an exterior angle of a triangle is equal to the sum of it's two opposite non adjacent interior angles.
In this case, set the exterior angle equal to the sum of the two given interior angle measurements:
(c) + (c - 26) = c + 50
First, simplify, combine like terms. Like terms are terms that share the same amount of the same variable:
c + c - 26 = c + 50
(2c) - 26 = c + 50
Next, isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Subtract c and add 26 to both sides of the equation:
2c (-c) - 26 (+26) = c (-c) + 50 (+26)
2c - c = 50 + 26
c = 76
76° is your answer.
