Answer:
1/12
Step-by-step explanation:
Total number of marbles = 5+7+4 = 16 marbles
Probability of picking a red marble = 5/16
Because the red marble is not returned back after being picked up, the total number of marbles is now 15.
Now,
Probability of picking a yellow marble = 4/15
The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12
Which expression is equivalent to |x| > 9?
A. x > –9 and x < 9
B. x > –9 or x < 9
C. x < –9 and x > 9
D. x < –9 or x > 9
Answer:
C
Step-by-step explanation:
when you do the absolute value you take out the sign
x > 9
but with absolute value there is also a negative answer. and with the greater than sign it would switch to less than.
x < -9

The sum of the number in each of the four rows is the same The sum of the numbers in each of the three columns is the sameThe sum of any row does not equal the sum of any column[tex]\bold{\underline{ Let's \: Begin}}[/tex]
According to the Second rule :-
[tex]\sf{ 75+b+83=76+80+d=a+81+85+78+c+e }[/tex]
[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + c + e ...(1)}[/tex]
According to the first rule :-
[tex]\sf{ 75+76+a+78 = b+80+81+c = 83+86+d+e}[/tex]
[tex]\sf{ 229 + a = 161 + b + c = 168 + d + e ...(2)}[/tex]
From ( 1 ) we got :-
[tex]\sf{ 158 + b = 166 + a, 156 + d = 166 + a }[/tex]
[tex]\sf{ b = 166 - 158 + a, d = 166 - 156 + a }[/tex]
[tex]\sf{ b = 8 + a, d = 10 + a ...(3)}[/tex]
Subsitute (3) in ( 2 ) :-
[tex]\sf{229+a = 161+8+a+c = 168+10+a+e}[/tex]
[tex]\sf{ 229+a = 169+a+c = 178+a+e}[/tex]
We can write it as :-
[tex]\sf{ 229+a = 169+a+c \:or\:229+a = 178+a+e}[/tex]
[tex]\sf{ c = 299-169+a-a\:or\:e = 229-178+a-a}[/tex]
[tex]\sf{ c = 60 \: and \: e = 51 }[/tex]
Subsitute the value of c and e in ( 1 ):-
[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + 60 + 51 }[/tex]
[tex]\sf{ 158 + b = 156 + d = 166 + a = 189}[/tex]
Now,
[tex]\sf{ For \: b, 158 + b = 189 }[/tex]
[tex]\sf{ b = 189 - 158 }[/tex]
[tex]\sf{ b = 31}[/tex]
[tex]\sf{ For \: d , 156 + b = 189 }[/tex]
[tex]\sf{ d = 189 - 156 }[/tex]
[tex]\sf{ d = 33}[/tex]
[tex]\sf{ For \: a, 166 + a = 189 }[/tex]
[tex]\sf{ a = 189 - 166 }[/tex]
[tex]\sf{ a = 23 }[/tex]
Hence, The value of a, b, c, d and e is 23, 31 ,60 ,33 and 51 .

Pls help I’m begging anyone.
They graph it in a werid way so I’m hoping u could take a screenshot and then graph it.
Answer:
Look at solution
Step-by-step explanation:
Remember that the x-axis is the time so you start at 0. The y-axis is the amount of snow so it says it starts at 1 inch so you start at (0,1).
When using coordinates remember (x,y) the x is the horizontal axis and y is vertical.
The next few steps deal with slope. The slope is always rise/run. so when it says it snowed for an average of 1 inch per hour, you go one up and one to the right to create the line. When it stopped snowing, the snow (i assume) stays the same so you just have a horizontal line for 5 hours indicating the same amount of snow. Then the snow becomes 3 per hour so you have to go up 3 from where you left off and over 1. Do that for 7 hours.
I hope you read this explanation because this is the basics of graphing. Next time you can try it by yourself :)

find the value of x?
Answer:
70
Step-by-step explanation:
The sum of all the angles of a triangle is 180.
so 47 + 63 + x = 180
110 + x = 180
x = 180-110
x = 70
The sum of the angles in a triangle is 180°. Therefore the value of x in the triangle attached is 70°.
Understanding Angles in a TriangleA triangle is a polygon with three sides, three angles, and three vertices (corners). It is one of the fundamental shapes in geometry and has several important properties.
Properties of Triangles
1. Interior Angles: The interior angles of a triangle always add up to 180 degrees. Each angle is measured in degrees, and the sum of all three angles is always a straight angle.
2. Exterior Angles: The exterior angle of a triangle is formed by extending one of its sides. The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.
3. Side Lengths: In a triangle, the sum of the lengths of any two sides is always greater than the length of the third side. This property is known as the Triangle Inequality Theorem.

At a real estate agency, an agent sold a house for $333,000. The commission rate is 4.5% for the real estate agency and the commission rate for the agent is 20% of the amount the real estate agency gets. How much did the agency make on the house? How much did the agent earn in commission?
Answer:
For the agency: $318,015
For the agent: $266,400
Step-by-step explanation:
$333,000 - 4.5 = $318,015
$333,000 - 20% = $266,400

3. Janice has room for 6 books on a shelf.
How many different ways can she arrange the books on the shelf?
Enter your answer in the box.
By counting the numbers of options for each selection, we will see that:
A) There are 10,000 different codes.B) There are 90 different combinations.C) There are 720 different combinations.How to get the numbers of combinations?A) The code has five digits, and the first digit is fixed (we know that it must be 7) so we only care for the other 4.
The second digit has 10 possible options.The third digit has 10 possible options.The fourth digit has 10 possible options.The fifth digit has 10 possible options.The total number of combinations is given by the product between the numbers of combinations:
C = 1*10*10*10*10 = 10,000 codes
So the correct option is the first one.
B) Again, we need to count the number of options for each possible element.
There are 5 drinks, 6 main dishes, and 3 desserts.
So for a meal of 1 drink, 1 main dish, and 1 dessert, the total number of different combinations is:
C = 5*6*3 = 90
There are 90 different possible meals.
C) How Janice can arrange the 6 books?
We need to count how many options we have for each place on the shelf.
In the first place, there are 6 options (one for each book).In the second place, there are 5 options (because we already placed one).On the third place, there are 4 options.And so on for the other 3 places.Then the number of combinations is:
C = 6*5*4*3*2*1 = 720
There are 720 ways of ordering the books.
