Finding the Likelihood of an Event
Each time you roll a number cube, a number from 1 to 6 lands face up. This is called an event.

Directions: List the possible outcomes for each event. Then, write where that event may fit on the scale (from impossible to certain).






Rolling a number less than 7


Example:

1, 2, 3, 4, 5, 6; 6 out of 6 possible rolls Likeliness: Certain [100%]

Rolling an 8





Rolling a number greater than 4





Rolling a 5





Rolling a number other than 6





Rolling an even number





Rolling a number less than 5





Rolling an odd number





Rolling a number divisible by 3

No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

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.)

Step-by-step explanation:

The interest earned is $60 and the balance of the account is $460. The interest and the balance of the account will be both calculated with their given formulas.

An expense or payment for using borrowed money is interest; it is occasionally stated as a percentage of the principal borrowed. It could also be applied to the returns on investments or savings. Interest is the cost that a borrower typically reimburses a lender for the use of their funds.

A. We must use the formula-

Interest = Principal x Rate x Time, to calculate the interest earned.

Here, Interest = $400 divided by 0.03 and multiplied by 5.

Earned interest is $60.

B. We must utilize the formula-

Balance = Principal + Interest, to determine the account's balance.

Balance = $400 + computed interest in this instance.

Balance: $400 + $60.

The account's balance is $460.

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.

Answer:

40 in.²

Step-by-step explanation:

First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):

A=1/2(bh)

A=1/2(3x4)

A=1/2(12)

A=6

6x4=24 in.²

Next, you have to find the area of the square:

A=bh

A=4x4

A=16

Now, add 24 and 16 together to get your answer of 40 in.².
