Multiply those two numbers 46 and 67 you get 3082.
SAS, those lines are the S-(sides) and the angle is in the middle of that makes sense, I hope this helped!
Answer:
27/14
Step-by-step explanation:
1/2 * 3 6/7 =
1/2 * 27/7
= 27/14
Answer:
answers are below
Step-by-step explanation:
<u>a. -6 ≤ 3x < 15</u>
steps in order to solve:
-6 ≤ 3x
= -6/3 ≤ 3x/3
= -2 ≤ x
3x < 15
= 3x/3 < 15/3
= x < 5
=> -2 ≤ x < 5
<u>b. -3 < 2x - 1 < 7 </u>
steps in order to solve:
-3 < 2x - 1
= 1 - 3 < 2x - 1 + 1
= -2 < 2x
= -2/2 < 2x / 2
= -1 < x
2x - 1 < 7
= 2x - 1 + 1 < 7 + 1
= 2x < 8
= 2x/2 < 8/2
= x < 4
=> -1 < x < 4
<u>c. 7 < -3n + 1 ≤ 13</u>
steps in order to solve:
7 < -3n + 1
= -1 +7 < -3n + 1 - 1
= 6 < -3n
= 6/-3 < -3n/-3
= -2 > n
-3n + 1 ≤ 13
= -3n + 1 - 1 ≤ 13 -1
= -3n <u><</u> 12
= -3n/-3 <u><</u> 12/-3
= n <u>></u> -4
=> -4 <u><</u> n < -2
graphs are below.
hope this helps and is right :)
Answer:
c. 0.7404
Step-by-step explanation:
We can use Bayes Formula,
We know every single value of that expression except P(C). We can calculate C by dividing into 2 cases: if the customer is new or not.
By the total probability theorem, we know that P(C) = P(C|N)*P(N) + P(C|N')*P(N') = 0.5*0.8 + 0.7*0.2 = 0.4+0.14 = 0.54
We replace P(C) on the equation above and we obtain
Thus, P(N|C) = 0.7407. Answer c is correct
I hope this helped you!
