The answer is b = 3. you subtract 24 from bothe sides and then divide by 2.
When there are two chords intersecting inside of a circle, there are four angles that are formed from this intersection. At the intersection, there are two sets of congruent vertical angles formed.
Angle Formed by Two Chords = 1/2(Sum of the Intercepted Arcs)
m<JPM = 1/2 (114 + 96) = 1/2 (210) = 105
Answer:
A ) 105
Answer:
AOC = 124°
Step-by-step explanation:
Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;
This can be written like so:
(3x + 94) + (x + 30) + (2x - 4) = 180
This equation can be solved to find x:
6x + 120 = 180
6x = 180 - 120
6x = 60
x = 10
AOC = 3(10) + 94
= 30 + 94
= 124
Answer:
a level of significance of 0.01 = 1%
Step-by-step explanation:
given
Z = 0.0001
mean μ=0.21 g/mi
variate x= 0.21 + 0.03
standard deviation σ= 0.05 g/mi.
N = sample population 20 cars
z = (x −μ
)/[σ
/√N ]
Z =
Z = 0.03/ (0.05/√20) = 0.03/0.0111
Z = 2.63 +- 0.0001
Z= 2.6301 or 2.6299
checking the level of significance table from a statistical book gives
a level of significance of 0.01 = 1%
therefore the null hypothesis is accepted.
30
As it an equilateral so it would be 60
Its split into two 60/2 = 30
