Two parallel lines are cut by a transversal as shown below.<br> Suppose m 6=63º. Find m 1 and m 3
tester [92]

Answer:

Both are 117 degrees.

Step-by-step explanation:

Since 6 and 8 are vertical angles, they are congruent. So, 8 is also 63 degrees. Angle 4 corresponds to angle 8, so it is also 63. Angle 2 and angle 4 are vertical, so they are also congruent. So, angle 2 is 63. Since angle 1 and 2 form a straight line (180 degrees), you can find angle 1 by subtracting 63 from 180. You get 117. And since 1 and 3 are vertical, 3 is also 117.

Suppose that K is a random variable. Given that Upper P (negative 3.95 less than or equals Upper K less than or equals 3.95 )equ
Irina-Kira [14]

Answer:

P [ K > 3.95] = 0.5633

Step-by-step explanation:

The interpretation of the given question goes thus;

Suppose that K is a random variable

P[-3.95 ≤ K ≤ 3.95] = 0.725  

where; P [ + 3.95 < K ] = P [K < - 3.95]

P[K< 3.95] - P [K > - 3.95] =0.725

P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725

P[k < 3.95] - 1 + P [ K < 3.95] = 0.725

3.95 P [ K < 3.95] -1 = 0.725

3.95 P [ K < 3.95] = 1.725

P [ K < 3.95] = 1.725/3.95

P [ K < 3.95] = 0.4367

P [ K > 3.95] = 1 - P[K< 3.95]

P [ K > 3.95] = 1 - 0.4367

P [ K > 3.95] = 0.5633
