The difference of two numbers is 74. Twice the first and thrice the Second sum up to 138. Find the two possible numbers . anyone??
Answer:
72 and -2
Step-by-step explanation:
x - y = 74
2x + 3y = 138
x - y = 74
y = x - 74
2x + 3(x - 74) = 138
2x + 3x - 222 = 138
5x = 360
x = 72
x - y = 74
72 - y = 74
-y = 2
y = -2

A toy machine has equal numbers of red, white, and blue foam balls which it releases at random. Ross wonders which color ball will be released next. Select the description of how you can use a standard number cube to model and predict this situation.
A.Let multiples of 2 represent red, let multiples of 3 represent white, and let the remaining numbers represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.
B.Since "red" has three letters and "one," "two," and "six" all have 3 letters, let these represent red. Since "blue" has 4 letters and "four" and "five" have four letters, let these represent blue. Since "white" has five letters and "three" has five letters, let this represent white. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.
C.Let 1 and 2 represent red, let 3 and 4 represent white, and let 5 and 6 represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.
D.Let even numbers represent red, let odd numbers represent white, and let prime numbers represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.
Answer:
Since there are three colors and a standard number cube has 6 sides, you can let the numbers 1 and 2 represent red, 3 and 4 represent white, and 5 and 6 represent blue. Then roll the number cube repeatedly, recording the results for each roll. After you have recorded a sufficient number of rolls, determine which color was rolled the most often.
RESULT
Let the numbers 1 and 2 represent red, 3 and 4 represent white, and 5 and 6 represent blue.
Option (C) predicts the probability of the above situation correctly is the correct answer.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
A toy machine has equal numbers of red, white, and blue foam balls which it releases at random.
Ross wonders which color ball will be released next.
A standard number cube is used to model and predict this situation.
A standard number cube has six faces namely 1,2,3,4,5,6.
There are three foam balls. If we assign two numbers for each foam, then we can able to predict the probability of next foam by rolling it for number of times.
Thus from the given options, Let 1 and 2 represent red, let 3 and 4 represent white, and let 5 and 6 represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability. This option determines the above situation.
Hence we can conclude that option (C) predicts the probability of the above situation correctly is the correct answer.

Step-by-step explanation:
we have two relations
[tex]a + c = 5[/tex]
[tex]9a + 4c = 30[/tex]
first rearrange the top equality for one of the variables
[tex]a = 5 - c[/tex]
now substitute into the second equation
[tex]9(5 - c) + 4c = 30[/tex]
perform the distribution and combine like terms
[tex]45 - 9c + 4c = 30[/tex]
[tex]45 - 5c = 30[/tex]
[tex] - 5c = - 15[/tex]

A game has a deck of cards with 5 red cards and 3 blue cards. You randomly choose one card and without replacing it choose another card. What is the probability of choosing a red card and then a blue card?
A: 2/7
B:10/49
C:15/56
D:15/64
Answer: C (15/56)
Step-by-step explanation:
probability of red card: 5/8
probability of blue card (after): 3/7
5/8 times 3/7 = 15/56 so C
Solve the equation below. you must show all your work, and have the correct answer.
9x + 10 = 12x – 11
Answer:
x=7
Step-by-step explanation:
You need to bring 9x to the right side and bring '-ll' to the left side so it will be 11+10 = 12x-9x. Then you calculate 11+10, which is 21, then you subtract 12x to 9x. Then it will be 21 = 3x. Lastly, you divide 3 on both sides of the equation and get x to be 7!
Answer:
x=7
Step-by-step explanation:
9x+10=12x-11
-9x. -9x. subtract 9x from both sides
10 = 3x-11
+11 +11. add 11 to both sides
21 =3x
divide by 3x (21 ÷3=7) therefore x=7

How do I graph -1, -4?
Answer:
Start at the origin and go to the left by one and go down by 4
Step-by-step explanation:
The x coordinate relates to the horizontal axis and the y axis refers to the vertical axis.
Before we start graphing we must always begin at the origin (0,0)
Since the x value is -1 we have to move left by 1 on the x axis
We would move to the left one value because negative is on the left side
For the y value, we would have to move 4 down on the y axis because this number is also negative.
So your graph should look like this

Answer:
The probability of picking a purple marble and spinning green is [tex]\frac{3}{28}[/tex].
Step-by-step explanation:
Since there are 7 marbles and 8 possible tiles to spin, the total amount of possible outcomes are 56. Out of the 56 different outcomes, 6 of them meet the requirement of picking a purple marble and spinning green, so the fraction to represent the situation is [tex]\frac{6}{56}[/tex] or [tex]\frac{3}{28}[/tex].

A
Step-by-step explanation:
It is A. The problem asks for the interval when the marlin's height is always increasing. Therefore, you want to look at the left half of the parabola, as the line is going into the peak. The right half is declining. The peak is at around 2 (on the x-axis), so you know that the ending interval number has to be 2. The marlin's height begins to go up starting at 0, so the interval is 0 <= x <= 2. Any number past two is a declining height, and the increase starts at 0.

"The sum of negative two and nine times a number is less than ninety four."
Answer:
I believe you would write the answer is 7 * x is less than 94 (use actual less than symbol for answer).
Step-by-step explanation:
"The sum of negative two and nine" is saying -2 + 9.
"times a number" is saying the answer of -2 + 9 is multiplied by a number, or x.
"is less than ninety four." is saying that -2 + 9 * x is less than (use symbol) 94.
So the equation looks like this:
-2 + 9 * x is less than 94.
Now you can simplify the equation:
-2 + 9 = 7
7 * x is less than(use actual less than symbol) 94.

At the beginning of 2007, the population of a certain state was 55.4% rural and 44.6% urban. Based on past trends, it is expected that 15% of the population currently residing in the rural areas will move into the urban areas, while 21% of the population currently residing in the urban areas will move into the rural areas in the next decade. What was the population distribution in that state at the beginning of 2017
Answer:
New Rural Urban distribution = 56.4 , 43.4
Step-by-step explanation:
Let the total population be = 100
The rural urban distribution = 55.4% & 44.6% of 100 = 55.4 & 44.6 respectively
Given , 15% of rural population shifts to urban. So, 15% of 55.4 ie = 8.31 shift from rural to urban.
Also, 21% of urban population shifts to rural. So, 21% of 44.6 , ie = 9.36 shift from urban to rural.
So, New rural population = old rural - rural to urban shift + urban to rural shift = 55.4 - 8.31 + 9.36 = 56.39 ≈ 56.4
New urban population = old urban - urban to rural shift + rural to urban shift = 44.6 - 9.36 + 8.31 = 43.55 ≈ 43.4
So, the new distribution is = 56.4 , 43.4
