Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

c) Punishments in the Code of Hammurabi were adjusted depending on the status of the perpetrator and the victim.

Step-by-step explanation:

The Code of Hammurabi reflected the social hierarchy of ancient Babylonia in that it differentiated punishments based on the social status of the perpetrator and the victim. For example, the code stipulated different punishments for crimes committed by a nobleman versus those committed by a commoner. This demonstrates that ancient Babylonian society was structured into a hierarchy, with different levels of privilege and responsibility assigned based on social status. The Code of Hammurabi, then, serves as a tangible expression of this social hierarchy, showing the ways in which the laws of the land reflected and reinforced existing power dynamics.

Reason:

6 black out of 4+6+5 = 15 total

6/15 = 0.40 is the experimental probability of selecting black.

Side note: The term "empirical probability" is the same as "experimental probability".

The experimental probability of selecting a black marble will be 0.40. The correct option is C.

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.

Probability = Number of favourable outcomes / Number of samples

Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.

Number of favourable outcomes = 6

Number of samples = 4+6+5 = 15

Probability = Number of favourable outcomes / Number of samples

Probability = 6 / 15

Probability = 0.40

Therefore, the probability will be 0.40.

Answer:

The answer is 25 :)

Step-by-step explanation:

Ok, this explanation will probably be super confusing so sorry about that but you get two statements about each aquarium. Aquarium 1 starts with 4.6 gallons and will INCREASE by 1.2 gallons every minute. So now you have statement one, so let's plug it into the y=mx+b formula. y is the result/ the answer you get, m is the slope/how much your points INCREASE or DECREASE. x is the variable you use to plug and b is your starting point. So you are trying to find the y which means we cannot plug it in yet so right now we have y=mx+b. your next letter to switch out is m. Like I said, M is how much each point increases or decreases and if you go back, the statement says "will increase by 1.2 gallons every minute." so your m is 1.2 and will be positive because of the keyword INCREASE. now we have y=1.2x+b. B is your starting point so let's go back to the statement to find the starting point/ number, it states "Aquarium 1 contains 4.6 gallons" meaning aquarium 1 starts with 4.6 gallons, so let's plug it into the equation. you should have y=1.2x+4.6, which is your first equation. Your next equation will be a bit more tricky. we start with y=mx+b and we start with finding m, how much each point will increase or decrease. "Isaac will begin DRAINING aquarium 2 at a rate of 0.8 gallon per every minute." so M will be .8 but notice the keywords DRAINING, meaning decreasing. So because Isaac isn't filling and increasing, but he is decreasing, you will make .8 negative. so you should currently have y=-.8x+b. Now let's find the starting point, or B.   "Aquarium 2 contains 54.6 gallons of water." making your m 54.6 gallons of water. Let's plug it in. y=-.8x+54.6. Now that you have to equations, this is how you will find when both equations have a point intercepting, or in other words, the answer you are looking for. you will remove the "y=" on both equations, and place an "=" between them. You should have something looking like this on your paper. "1.2x+4.6 = -.8x+54.6". Now you are going to combine like terms, so look on both sides of the equation and look for the 2 numbers with no "x" next to them. You should find "4.6" on your left and "54.6" on your right side of the equal sign. you are going to equal out "4.6" with itself by writing "-4.6" underneath it but because you did this on one side of the equal sign, you have to do it on the other side but before you do so you should have "1.2x = -.8x+54.6". now let's subtract "4.6" to "54.6" you will write "-4.6" underneath "54.6" to get your new number, "50". your problem should look like "1.2x = -.8x + 50". now we are going to do the same for your number's with an "x" by it. on the right side of the equation, you will cancel out "-.8x". notice it's NEGATIVE so, in order to cancel out a negative number, you just make the number positive. so you will ADD ".8x" to "-.8" to get 0 but because you added ".8x" to one side, you have to do it to the other side. Let's check what we have first, you should have "1.2x = 50". so now let's ADD ".8x" to "1.2x". you will get "2x" so now you should have both equations simplified like this, "2x = 50" and now we are going to make x one so we will divide "2x" by "2" to get "x", but because you did this to one side, you have to do it to the other. so now you divide "50" by "2" to get 25. now you should have written down "x = 25". Thank you so much for reading this and please let me know if this was helpful or confusing. :)))

The time at which both aquariums contain the same amount of water is 25 minutes and this can be determined by forming the linear equation.

Given :

The following steps can be used in order to determine the time at which both aquariums contain the same amount of water:

Step 1 - Let the time be 't' at which both aquariums contain the same amount of water.

Step 2 - The amount of water in the Aquarium I at time 't' is given by:

V = 4.6 + 1.2t

where V is the total amount of water at time 't'.

Step 3 - The amount of water in the Aquarium II at time 't' is given by:

V' = 54.6 - 0.8t

where V' is the total amount of water at time 't'.

Step 4 - So, time at which both aquariums contain the same amount of water is given by:

V = V'

4.6 + 1.2t = 54.6 - 0.8t

Step 5 - Simplify the above equation.

50 = 2t

t = 25 minutes

Therefore, the correct option is C).

Answer:

What is it steepest slope?

Step-by-step explanation:

Answer:

5.906 x 10^9

Step-by-step explanation:

(6.25 x 10^9) − (3.44 x 10^8).

step 1: make the exponents have common value

Move decimal point of 3.44 to the left once and add 1 to it's exponents.

that is 3.44 x10^8 becomes 0.344 x 10^9

= 6.25 x 10^9 - 3.44 x 10^8

= 6.25 x 10^9 - 0.344 x 10^9

step 2: bring out the common factor 10^9 since the exponents are the same.

Also, subtract the decimal numbers.

= (6.25 -0.344) 10^9

6.25 - 0.344 = 5.906

Therefore, the result is 5.906 x 10^9.

Answer: C

Step-by-step explanation:

Well Well, so from Lesson 4 to 6 The $ added is 55 then from lesson 6 to 9 the $ added is 82.50. So you subtract 82.50-55=$27.50 which is the cost per lesson. Then to find out the initial fee you do 4*27.50=110 which means that you subtract 145-110=$35 and you get the initial fee. What you do to get the the initial fee is you go back to 0 lessons that's why I multiplied 4*27.50 and subtract that from the cost 145 and u get the initial fee!

Answer:

\(a=3\text{ and } b=-17\)

Step-by-step explanation:

We are given that:

\(5x^2+bx-12=(5x+a)(x-4)\)

First, we can distribute the right-hand side:

\(5x(x-4)+a(x-4)\)

Distribute:

\(=5x^2-20x+ax-4a\)

Rewrite:

\(=5x^2+(-20+a)x-(4a)\)

Since it is equivalent to the above expression, the coefficients of the variables must match. This means that:

\(-20+a=b\text{ and } 12=4a\)

Solving for a in the second equation gives:

\(a=3\)

Therefore:

\(b=-20+3=-17\)
