Complete question:
Jason has two bags with 6 tiles each. The tiles in each bag are shown below:
1 2 3 4 5 6
Without looking, Jason draws a tile from the first bag and then a tile from the second bag. What is the probability of Jason drawing the tile numbered 2 from the first bag and the tile numbered three from the second bag?
Answer: 1/36
Step-by-step explanation:
Number of tiles in each bag = 6
Probability of drawing tile numbered 2 from the first bag and the tile numbered 3 from the second
Probability of drawing number 2 from first bag :
P(numbered 2) = (required outcome / possible outcome)
P(numbered 2) = 1/6
Probability of drawing number 2 from first bag :
P(numbered 3) = 1/6
Since they are independent events :
P(drawing 2 from bag one and 3 from bag 2) :
1/6 × 1/6 = 1/36

Katherine is requesting a large print job from the printing office. She has a 51-page document she wants printed double-sided and stapled. She needs 3,550 copies.How many pieces of paper are required to complete this request?
Answer:
181,050 pieces of paper.
Step-by-step explanation:
If she needs 3,550 copies of a 51 page document, you can easily solve this problem by multiplying the amount of copies needed by pages per copy. 3,550 x 51 is 181,050.

Select a setting so that each given point will lie within the viewing window.
(-13,3), (0,0).(-2,-7)
Answer:
The given points are
[tex](-13,3)\\(0,0)\\(-2,-7)[/tex]
The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is
[tex]x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5[/tex]
With a scale of 2 units.

Define dot product, inner product, cross product.
Answer:
Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.
Step-by-step explanation:
Answer:
- A dot product is the product of the magnitude of the vectors and the cos of the angle between them.
- A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other.
- An inner product is a generalization of the dot product.
Step-by-step explanation:
Dot product - the sum of the products of the corresponding entries of the two sequences of numbers. Geometrically, it is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them. These definitions are equivalent when using Cartesian coordinates.
Cross Product - The cross product is a mathematical operation which can be done between two three-dimensional vectors. It is often represented by the symbol. After performing the cross product, a new vector is formed. The cross product of two vectors is always perpendicular to both of the vectors which were "crossed".
Inner product - In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.

There are 17 trees along the road from Basil's home to a swimming pool. On his way way to and from a swim Basil marks some trees with a red stripe. On his way to the pool he marks the first, the third, the fifth tree and so on. On his way back again, he marks the first tree he comes to, the fourth tree, the seventh tree and so on, missing out two trees each time. By the time he gets home how many trees have no mark?

Aron has a bag of marbles that contains three red (R) marbles, four green (G) marbles, and three blue (B) marbles. 3 red marbles, 4 green marbles, and 3 blue marbles. Which expression represents the probability of randomly selecting a green (G) marble, replacing it, and then randomly selecting a red (R) marble? StartFraction 1 over 10 EndFraction (StartFraction 1 over 10 EndFraction) StartFraction 4 over 10 EndFraction (StartFraction 3 over 10 EndFraction) StartFraction 4 over 10 EndFraction (StartFraction 3 over 9 EndFraction) One-fourth (one-third)
Answer:
3/25
Step-by-step explanation:
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(green) = number of green / total = 4/10 = 2/5
We replace it
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(red) = number of red / total = 3/10
P(green, replace,red) =2/5*3/10 = 3/25

If f(x) = 5x + 2x and g(x) = 3x - 6, find (f+g)(x).
O A. 5X + x-6
O B. 5x – X+6
O C. 10x- 6
O D. 5* + 5x – 6
Answer:
10x -6
Step-by-step explanation:
f(x) = 5x + 2x = 7x
g(x) = 3x - 6
f(x) + g(x) = 7x+ 3x-6
= 10x -6

The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11
the smallest angle is 35 degrees
work out angles A,B and C
This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.
Out of 1,000 students, 80 were asked by random sampling what color they would prefer for their first car. Their responses are shown in the table below.
Answer:
175
Step-by-step explanation:
To find a proportion, you need to put both parts over the total. You would put the part of silver (14) over the total (80) and the part you are trying to find (X) over the total number of students (1,000). Then you cross multiply 14 x 1,000 and divide by 80 giving you 175 silver cars.

A company is worth $79,600,000. Write this number in scientific notation.
79,600,000=
Answer:
The answer is 7.96×10⁷ .
Step-by-step explanation:
As the decimal moves to the left , you have to add one more power to the base 10 :
e.g
7 960 000.0 = 7 960 000×10¹
796 000.00 = 796 000×10²
79 600.000 = 79 600×10³
7 960.0000 = 7 960×10⁴
796.00000 = 796×10⁵
79.600000 = 79.6×10⁶
7.9600000 = 7.96×10⁷

Morgan has 5 blue t-shirts , 3 green t-shirts and 2 red t-shirts . She randomly picks a shirt. What is the probability of choosing each color?
Answer:
Confusing question but I think it's 10:10
Step-by-step explanation:
Total outcome = 5:3:2
= 5+3+2
=10.
Probability = number of success
Total outcome
= 10/10
Therefore the probability of Morgan choosing each colour is 10:10.
6x^2 - 19x + 10
Factor
Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.

Step-by-step explanation:
A drawer contain pens , 14 blue pens and 8 black pens , 14 silver paper clips , and 16 white paper clips . If you randomly select a pen and paper clip from the drawer , what is the probability that you select a red pen and white paper clip
Step-by-step explanation:
Total pens = 22
Total clips = 30
Probability of red pen = 0
Because there are no red pens
Probability of white clip = 16/30 = 8/15
