Answer:
are often inaccurate.
Step-by-step explanation:
Subjective probability can be defined as the probability of an event happening based on the opinion, personal judgment, perception or experience of a person.
This ultimately implies that, subjective probabilities are not based evidence, quantitative results, facts, historical or empirical data (informations) and as a result, they are considered to be inaccurate.
Hence, subjective probabilities are often inaccurate.
An example of subjective probability is a financial advisor stating that, there is a 20% chance that the price of a security will increase by next week.
how much water must be added to a 9-liter solution that contains 3% extract on baneberry to get a solution that contains 2% extract of baneberry
Answer:
Amount water added = 4.5 L
Step-by-step explanation:
Given:
Amount of solution = 9 L
Amount of bane-berry = 3% of 9 L = 0.27 L
Computation:
Assume;
Amount water added = x L
Total solution = 9+x L
New percentage of bane-berry = 0.27x100/(9+x)
2 = 0.27*100/(9+x)
x = 4.5 L
Amount water added = 4.5 L

Roberto has a certain number of songs on his MP3 player. Each week, he plans to add 4 more songs. After 5 weeks, he had 40 songs on his MP3 player. Which statement is true?
A. Roberto adds 5 songs on his MP3 player per week.
B. Roberto adds 10 songs on his MP3 player per week.
C. The initial number of songs on Roberto’s MP3 player is 10.
D. The initial number of songs on Roberto’s MP3 player is 20.
Please and the work for it too
Answer:
the answer is D. because 5×4=20, he had a total of 40 at the end so you subtract 20 from 40 and his initial amount of songs was 20.

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
cost of gas with tax is $3.81 per gallon
But gas should be less than 14 gallons and not more than 8 gallons.
So,
=3.81×8
=30.48
3.81×14
=53.34
Hence, the range is 30.48 to 53.34,

Answer:
In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.
Assume a cube has side lengths of 2 inches. What is the area of the base of that cube? Does it matter which face we call the base? What is the volume of that cube? Instead, assume the cube has side lengths of 3 inches. What is the area of the base now? The volume? Based on that, what do you think the relationship is between side length, area, and volume? Would that still be true even if it is not a cube? (Put another way, if the side length is x, what is the area and volume?)
Answer:
Step-by-step explanation:
Volume of a cube:
V = a3
Surface area of a cube:
the area of each face (a x a) times 6 faces
S = 6a2
Face diagonal of a cube:
By the pythagorean theorem we know that
f2 = a2 + a2
Then f2 = 2a2
solving for f we get
f = a√2
Diagonal of the solid cube:
Again, by the pythagorean theorem we know that
d2 = a2 + f2
substituting f into this equation we get
d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2
solving for d we get
d = a√3

A student bake sale is selling baked goods. In total they sell 100 pieces of baking, Chocolate chip cookies sell for $0.50 and Muffins for $1.25. The total money earned from the bake sale came to 68.75. How many muffins did they sell?
Answer:
The number of muffins sold by the students is:
25 muffins.Step-by-step explanation:
First, we name the variables:
C= Number of chocolate chip cookies sold.M= Number of muffins sold.Now we establish the equations with the information given in the exercise:
C + M = 1000.5C + 1.25M = 68.75We can use in this case the reduction method, to this, we multiply the first equation by (-0.5) obtaining the equation 3:
[C + M = 100] * (-0.5) = -0.5C - 0.5M = -503. -0.5C - 0.5M = -50
We operate the equations 2 and 3 to eliminate the variable C:
(0.5C + 1.25M = 68.75) + (-0.5C - 0.5M = -50) = (0.75M = 18.75)And we solve for the variable M:
0.75M = 18.75M = 18.75/0.75M = 25We could stop here because we know the number of muffins now, but with the value for M, we can solve the value of C with the first equation to check the answer is correct:
C + M = 100C + 25 = 100C = 100 - 25C = 75In the end, we replace the values in the second equation and verify if the answer is correct:
0.5C + 1.25M = 68.750.5 * (75) + 1.25 * (25) = 68.7537.5 + 31.25 = 68.7568.75 = 68.75Consider the original trapezoid and the reduction.

5x - 18 ≤ -8
As with any 2-step equation, add the opposite of the constant that is on the same sides as the variable term.
5x -18 +18 ≤ -8 +18

Explanation:
y = x - 4
y = 6x - 10
-----------------------
x - 4 = 6x - 10
-4 = 6x - x - 10
10 - 4 = 5x
x = 1.2
-----------------------
y = x - 4
y = 1.2 - 4
y = -2.8

Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regularly. However, her grandmother gave her the generous gift of $2500 for her birthday and suggested she invest it in a GIC because it’s low risk. She shopped around and found a 4 year GIC investment that earns 2.8% interest annually. How much will Anna have at the end of her four year investment?
Answer:
She will have $2792 at the end of her four year investment
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Gift of $2500:
This means that [tex]P = 2500[/tex]
She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.
This means that [tex]t = 4, r = 0.028, n = 1[/tex].
How much will Anna have at the end of her four year investment?
This is A(4). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(4) = 2500(1 + 0.028)^{4} = 2792[/tex]
She will have $2792 at the end of her four year investment
