Your friend has a bag of marbles. Your friend says that there is a 100% chance that you pick out a red marble and a 0% chance that you pick a green one.
What can you conclude about the colors of the marbles inside of your friend's bag?
Can you determine exactly how many marbles are in the bag? Why or why not?
Answer:
1. They are all red. 2. There is no possible way to come to a conclusion
Step-by-step explanation:
If there is a 100% chance you will draw a red marble, they all have to be red or it would not be a 100% chance.
We can't conclude how many marbles are in the bag because the question states nothing about how many marbles there are.
A driver averages 42 miles per hour and took 15 hours to travel between two cities what is the distance between the two cities
Answer:
The distence bettween the two cities is 630miles
Step-by-step explanation:
So you take 42 and multiply it by 15 and you get 630.
The following data are the distances between a sample of 20 retail stores and a large distribution center. The distances are in miles.
29; 32; 38; 40; 58; 67; 68; 69; 76; 81; 85; 95; 96; 96; 99; 106; 112; 127; 145; 150
Find the value that is one standard deviation below the mean. (Round your answer to one decimal place.)
Please help!!!!
Mean = sum of all numbers / 20 = 1669 / 20 = 83.45
Standard deviation = 7.86
Z-score = -1
So...
Z = (x - mean) / standard deviation
x = Z * standard deviation + mean = -1 * 7.86 + 83.45 = 75.59
Rounded: 75.6
Round 7.788 to the nearest hundredth.
Answer:
7.79
Step-by-step explanation:
A hundredth is the second number after the decimal. For example, in the number 100.234, the "3" would be the hundredth, the "2" would be the tenth, and the "4" would be the thousandth.
To round to the nearest hundredth, you have to look at the thousandth because when rounding, you look at the next number to decide whether to round up or down.
Since 8 is in the thousandth place in this question, and 8 is bigger than 5, you round up. So, you round the "8" in the hundredths place up to 9.
Therefore, you get 7.79.
Finding the slope intercept form of the line passing through the point ( 7,-2 ) and parallel to the line
Answer:
y = -8x + 54
Step-by-step explanation:
Since the lines are parallel, their slopes are the same, leaving you with y = -8x.
That equation at x = 7 would make y -56, but we want it to be -2. Therefore we add a 54 in the end, leaving you with y = -8x + 54.

Subtract 3 2/5 from 5 3/4
Answer:
[tex]-2\frac{7}{20}[/tex]
Step-by-step explanation:
Given the following question:
[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]
To find the answer we first need to convert the mixed numbers into improper fractions, find the common denominator, subtract the denominators, and of course convert the improper fraction back into a mixed number.
[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]
[tex]3\frac{2}{5}=5\times3=15+2=17=\frac{17}{5}[/tex]
[tex]5\frac{3}{4} =4\times5=20+3=23=\frac{23}{4}[/tex]
[tex]\frac{17}{5} -\frac{23}{4}[/tex]
Find the common denominator:
[tex]CD=20[/tex]
[tex]\frac{17}{5} \times4=\frac{68}{20}[/tex]
[tex]\frac{23}{4} \times5=\frac{115}{20}[/tex]
[tex]\frac{68}{20} -\frac{115}{20}[/tex]
[tex]68-115=-47=-\frac{47}{20}[/tex]
[tex]=-\frac{47}{20}[/tex]
Convert the improper fraction into a mixed number:
[tex]-\frac{48}{20}[/tex]
[tex]-\frac{47}{20} =47\div20=-2\frac{7}{20}[/tex]
[tex]=-2\frac{7}{20}[/tex]
Your answer is "-2 7/20."
Hope this helps.
[tex]2\frac{7}{20}[/tex] is the mixed number we get by subtracting [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex].
To subtract [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex], we first need to convert both mixed numbers to improper fractions.
[tex]5\frac{3}{4}[/tex] = (4 × 5 + 3) / 4 = 23/4
[tex]3\frac{2}{5}[/tex] = (5 × 3 + 2) / 5 = 17/5
Now we can subtract the two fractions:
23/4 - 17/5
To subtract fractions, we need to have a common denominator.
The common denominator for 4 and 5 is 20.
We'll convert both fractions to have a denominator of 20:
23/4 = (23 × 5) / (4 × 5) = 115/20
17/5 = (17 × 4) / (5 × 4) = 68/20
Now we can subtract the fractions:
115/20 - 68/20
= (115 - 68) / 20
= 47/20

What is the correct interpretation of the probability of getting an 11 when a pair of dice is rolled? Interpret an event as significant if its probability is less than or equal to 0.05.
Answer:
1/18
Step-by-step explanation:
We are considering that we have 2 dices with 6 faces each (so, the probability to getting any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:
Dice 1= 6 and Dice 2 =5 or Dice 1= 5 and Dice 2 =6
So, the probability of the event is given as:
P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.
As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).

7. Given b= 4, c = 10, and A = 34 degrees, use the Law of Cosines to solve for a. Round your answer to the nearest whole number.
8. Given a = 11, C = 131 degrees, and b = 8, use the Law of Cosines to solve for c. Round your answer to the nearest tenth.
9. Given c = 9.6, b = 5.9, and a = 10.5, use the Law of Cosines to solve for C. Round your answer to the nearest degree.
Answer: (7) 7.0 (8) 17.3 (9) 64.7°
Step-by-step explanation:
Law of Cosines is: a² = b² + c² - 2bc · cos A
or: b² = a² + c² - 2ac · cos B
or: c² = a² + b² - 2ab · cos C
7) b = 4, c = 10, ∠A = 34
a² = b² + c² - 2bc · cos A
= 4² + 10² - 2(4)(10) · cos 34°
= 16 + 100 - 80 (0.829)
= 116 - 66.323
= 49.677
a = [tex]\sqrt{49.677}[/tex]
a = 7.0
8) a = 11, b = 8, ∠C = 131
c² = a² + b² - 2ab · cos C
= 11² + 8² - 2(11)(8) · cos 131°
= 121 + 64 - 176 (-0.656)
= 185 + 115
= 300
c = [tex]\sqrt{300}[/tex]
c = 17.3
9) a = 10.5, b = 5.9, c = 9.6
9.6² = 10.5² + 5.9² - 2(10.5)(5.9) · cos C
92.16 = 110.25 + 34.81 - 2(10.5)(5.9) · cos C
92.16 = 145.06 - 123.9 cos C
-52.9 = -123.9 cos C
0.427 = cos C
cos⁻¹ (0.427) = C
64.7° = C
