Find the measure of APBˆ. A. 130 B. 63 C. 50 D. 230

Mathematics
1 answer:
Daniel [21]3 years ago
3 0

Answer:

65

Step-by-step explanation:

TAB is an isosceles triangle by the point to tangent theorem theorem.

BAT and BAT are congruent because of the isosceles triangle definition.

CAT and ABT are right angles by the tangent theorem.  

Thus, CAB and CBA are both 90 - 65 = 25.

ACB is 130 because triangles' angles add up to 180.

APB is one half of ACB by the inscribed angles theorem.

Volume of a cone formula: V = πr²*h/3

V = volume

r = radius

h = height

Solve with the given values.

V = π(7)²*19/3

V = π(49)*19/3

V = 153.86*19/3

V = 974.94...

Round to the nearest one.

974.94... → 975.0

Therefore, the answer is 975.0yd³

Best of Luck!

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal
frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)=\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)=1 - 0.99^{50}=0.395
