Answer:
Probability expression = 1 - n/7 - n/8 + n^2 / 56
Probability single fraction based on example = 3/28
Step-by-step explanation:
Total sweets = 8. n jelly beans , 8 - n cola bottles
Prob (getting 1st cola bottle) = Cola bottles / Total sweets = (8-n) /8
Prob (getting 2nd cola bottle) = remaining cola bottles / remaining total sweets = (8 - n - 1) / (8-1) = (7-n) / (7)
Prob (getting both 1st & 2nd cola bottle) = [ (8-n) /8 ] x [ (7-n) / 7 ]
(1 - n/8) x (1-n/7) = 1 - n/7 - n/8 + n^2 / 56
Eg : 5 jelly beans , 3 cola bottles
Similarly, Prob (2 cola bottles) = 3/8 x 2/7 = 6 / 56 = 3/28

Answer:
[tex] \frac{1}{m - n} - \frac{m + n}{m {}^{2} - n {}^{2} } [/tex]
Factor if necessary:
x²-y²=(x+y)(x-y) use this formula
[tex]\frac{1}{m - n} - \frac{m + n}{ {(m + n)(m - n)}}[/tex]
[tex]\frac{1}{m - n} - \frac{1}{ {(m - n)}}[/tex]
Take lcm and subtract:
=0
Answer:
0
Step-by-step explanation:
We need to simplify the given expression . The given expression is ,
→ 1/ ( m - n) - (m + n)/ ( m² - n² )
→ 1/ ( m - n) - ( m + n)/(m+n)(m-n)
Using a² - b² = (a+b)(a-b) Now cancel m+n in numerator and denominator .→ 1/( m - n) - 1/ ( m - n)
→ 0
Hence the required answer is 0 .What is 2p + (3q + 2) = (2p + 3q) + 2
Answer:
associative property of addition
Step-by-step explanation:
2p + (3q + 2) = (2p + 3q) + 2
There are no terms that can be combined since there are no like terms
We are using the associative property to move the parentheses from one group of terms to the other.

If you roll the die 60 times, how many twos can you expect to roll?
Answer:
10
Step-by-step explanation:
Rolling a single six-sided die, you would get two 1/6th of the time because there is one two out of the six sides.
So 60 rolls would be 60*(1/6)=60/6=10

What is the missing angle measure?
Answer:
x = 33
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x
x = 180 - (90 + 57) = 180 - 147 = 33

Find the direction of the given vector. -6,5
9514 1404 393
Answer:
140.2°
Step-by-step explanation:
The direction of vector (x, y) is the angle arctan(y/x). The signs of the components tell you this is a 2nd quadrant angle. The arctan function only gives values in the range -π/2 to +π/2, so 180° must be added for 2nd and 3rd quadrant angles.*
arctan(5/-6) = 180° -39.8° = 140.2° . . . . CCW from the +x axis
_____
* Spreadsheets and some calculators have an ATAN2(x, y) function that uses the signs of the coordinates to give the result in the correct quadrant.
What is the greatest number of right angles a triangle can contain?
#
Choice
A.
1
B.
3
C.
0
D.
2
.
Answer:
A) 1
Step-by-step explanation:
a triangle has 180° and a right angle has 90°
triangles have 3 angles
2 right angles would make up 180° therefore, it can only contain 1 right angle
Answer:
There can be only 1 right angle(90°) so answer A
Step-by-step explanation:
If a triangle is equal to 180 °
And each right angle is equal to 90°
Then there can be 2 or 3 becouse if it was 2 it would be a full 180° but we still need 1 more corner and if it would be 3 right angles then it would be 270 with is way farther then the capability of a triangle.

Hope it is helpful....Please help me in maths
Answer:
below, and I hope that this helps you solve it.
Step-by-step explanation:
So what you would want to do is do this.
10×10= 100 + 5×10= 50 + 3×10=30 + 5×3=15
So now you want to add, so add
100 + 50 + 30 + 15 and that would equal to 195 and now you want to divide 195 ÷ 2 and that would equal to 97.5
5. The owner of a bookstore developed a model for determining the price of rare comic books.
The price, P, of each book should vary directly with the number of people, N, that have
requested the book and inversely to the number of such books in existence, M. If N = 10 people,
M = 10,000 copies, and P = $5, then find P for N = 200 people and M = 100 copies.

Step-by-step explanation:
plz do tell me if i need to explaine
The frequency table is made and the Relative frequency for the range 11 – 15 is 0.2 .
What is Frequency ?Frequency is the number of times any event is occurring .

In golf shooting par is scored as a 0. A score of 2 below par is called an eagle. Jacobs friend Michelle scored an eagle on each of her first five holes. Explain how you would use addition to find the product of-2 and 5 using the integer tiles and the number line
Answer:
Kindly check explanation
Step-by-step explanation:
Using the integer tiles :
Drawing 2 tiles each time an eagle is obtained, this gives:
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Using the number line,
Each unit on the number line = - 2
Any time an eagle scored ; take a unit step to the left.
This give ls a unit step 5 times
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Using direct multiplication :
-2 * 5 = - 10 as it means - 2 in 5 places ; similarly, scoring - 2 five times will give - 10
Also note :
Either - 2 * 5 or - 5 * 2 is the same due to commutativity property of multiplication
