Which of the following is a zero-dimensional geometric object?. A.A plane. B.A point. C.A ray. D.A line.

lana66690 [7]

A point is actually a zero dimensional geometric object. The reason behind selecting this answer is that a point does not have a length, width or height. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer comes to your help. <span />

Please solve for M<QTR

Andru [333]

Answer:

m∠QTR = 98°

Step-by-step explanation:

From the picture attached,

Radii of the circle are TQ and TR measuring equal lengths.

Therefore, ΔTQR is a isosceles triangle.

Opposite angles of the equal sides will be equal in measure.

m∠RQT = m∠TRQ = 41°

By angle sum theorem,

m∠RQT + m∠TRQ + m∠QTR = 180°

41° + 41° + m∠QTR = 180°

m∠QTR = 180° - 82°

= 98°

Therefore, m∠QTR = 98°

Jada is standing 10 feet from the base of the tree and spots a nest sitting on a branch. the angle of elevation from the ground

kogti [31]

Answer:

h = (10 ft)(1.428) = 14.28 ft

Step-by-step explanation:

Represent the height of the nest by h. This is the vertical side of a triangle. The horizontal side is 10 ft.

The following relationship is true:

tan 55 degrees = (opposite side) / (adjacent side), and in this case,

tan 55 degrees = h / 10 ft, so that:

h = height of nest = (10 ft)(tan 55 degrees), or

h = (10 ft)(1.428) = 14.28 ft

Will give brainlyest

faust18 [17]

Answer: (1) 42%, (2) 60%, (3) 75%.

Step-by-step explanation: The calculations are as follows

(1) Given that

P(A) = 0.70, P(B) = 0.25 and P(A and B) = 0.30 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

$P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.30}{0.70}=0.42.$

Therefore, the answer is 42%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

(2) Given that

P(A) = 0.40, P(B) = 0.60 and P(A and B) = 0.24 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

$P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.24}{0.40}=0.60.$

Therefore, the answer is 60%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

(3) Given that

P(A) = 0.33, P(B) = 0.50 and P(A and B) = 0.25 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

$P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.25}{0.33}=0.75.$

Therefore, the answer is 75%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

Thus, the answers are 42%, 602% and 75%.
