Answer:
810
Step-by-step explanation:
In this case the sample space would be the number of combinations that can be made with the numbers from 1 to 30 with the letters of the alphabet, from "a" to "z", for example:
A1, A22, C4, F9, etc
Now we know how many numbers are 30, now the alphabet has 27 letters, therefore, the number of combinations are:
27 * 30 = 810
Which means that the total number of results is 810.
Factor the Polynomial by solving x^2 + bx + c = 0.
m^2 - mv - 56v^2
Factor by grouping.
(m−8v)(m+7v).
x^2 + bx + c = 0
Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
-15 -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8
Same thing vertical so you would have
16x+7=87
-7 -7 from both sides
16x=80
divide by 16 from both sides
x=5
Answer:
Yes, and if you need extra help try yay math
Step-by-step explanation:
From 2 to 101 , the perfect square numbers are ,
- 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .
Total number of possible outcomes = 100.
Total number of favourable outcomes = 9 .
Hence ,
→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>
