This values is obtained from the standard normal table
The confidence level interval can be mathematically represented as
substituting values
=>
Answer:
x = 9 ⇒ second answer
Step-by-step explanation:
∵ (a + 3)(-2a² + 15a + 6) =
-2a³ + 15a² + 6a - 6a² + 45a + 18 =
-2a³ + 9a² + 51a + 18
∵ (a + 3)(-2a² + 15a + 6) = -2a³ + xa² + 51a + 18
∴ -2a³ + 9a² + 51a + 18 = -2a³ + xa² + 51a + 18
∴ x = 9
Answer:
The area would be 32
Step-by-step explanation:
Let's call the side lengths a and b, so then therefore a + b = 12
after this, we know that the length of a is 4, from the distance formula, and so the length of b is 8, so the area is 4*8 which is 32
In order from least to greatest:
| 4 2/7 |
| -4 3/7 |
| -4 6/7 |
| 5 1/7 |
|-5 3/7|
Answer: "C"
roots would make the function "0"
so just plug in the numbers...
with a + 12 you need minuses to cancel out...
B & C can not be the answer...
A is -i -3 + 4i - 12 which also is not 0
C is : 8i -12 -8i +12 WHICH DOES = 0
