Answer:
m<A = 133
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
That means that m<A + m<C = 180.
m<A + m<C = 180
4x + 5 + x + 15 = 180
5x + 20 = 180
5x = 160
x = 32
m<A = 4x + 5
m<A = 4(32) + 5
m<A = 128 + 5
m<A = 133
Answer:
12 meters
Step-by-step explanation:
Answer:
w + w
Step-by-step explanation:
w + w * 1 is the coefficent of w *
1w + 1w
(1+1) w
2w
So we are given the mean and the s.d.. The mean is 100 and the sd is 15 and we are trying the select a random person who has an I.Q. of over 126. So our first step is to use our z-score equation:
z = x - mean/s.d.
where x is our I.Q. we are looking for
So we plug in our numbers and we get:
126-100/15 = 1.73333
Next we look at our z-score table for our P-value and I got 0.9582
Since we are looking for a person who has an I.Q. higher than 126, we do 1 - P. So we get
1 - 0.9582 = 0.0418
Since they are asking for the probability, we multiply our P-value by 100, and we get
0.0418 * 100 = 4.18%
And our answer is
4.18% that a randomly selected person has an I.Q. above 126
Hopes this helps!
