Answer:
29
Step-by-step explanation:
Use definition of conditional probability:
where
A = the student is a freshman,
B = the student is a male
From the table,
So,
The answer is A. (1, 4), because when the values are substituted in to the equations, you get 1 = 4 - 3 and 1 + 12 = 13, which are both correct. I hope this helps!
Answer:
The value of given expression = - 5mx
Step-by-step explanation:
Given expression;
10xm - 8mx + 6xm - 13xm
Find:
The value of given expression
Computation:
⇒ 10xm - 8mx + 6xm - 13xm
Step 1 ;
Rearrange expression;
⇒ 10mx - 8mx + 6mx - 13mx
Step 2 ;
Adding all terms
⇒ 10mx + 6mx - 8mx - 13mx
Step 3 :
Subtract term
⇒ 16mx - 21mx
⇒ -5mx
The value of given expression = - 5mx
We know that
angle (3x) and angle (9x) are supplementary angles
so
3x+9x=180°------> 12x=180°------> x=180°/12-----> x=15°
angle (9x) and angle (1) are supplementary angles
so
9x+∡1=180---------> 9*15+∡1=180
∡1=180-9*15---------> ∡1=180-135------> ∡1=45°
the answer is
∡1 is 45°
alternative method
angle 1 = angle 3x----------> vertical angles
∡1=3x-----> 3*15-----> 45°
