Answer:

3. It is likely.

Step-by-step explanation:

Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side

Then the areas covered will be as:

point 20 = πr² = S
point 15 = π(2r)² - πr² = 3πr² = 3S
point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
point 5 = π(4r)² - π(3r)² = 7πr² = 7S

Total area of the dartboard is S+3S+5S+7S = 16S

The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S

The probability of scoring at least 10 points is:

9S/16S = 0.5625

As it is between 1/2 and 1, the probability is in 'likely' region

So the correct answer choice is: 3. It is likely

PQ is tangent to OR at point P. Find mZQ. A. 17° B. 27° C. 63° D. 73°

mamaluj [8]

Answer:

Step-by-step explanation:

The angle between the tangent PQ and the radius RP at the point of contact P is 90°

The sum of the 3 angles in Δ PQR = 180° , thus

∠ Q = 180° - (90 + 73)° = 180° - 163° = 17° → A

A disadvantage of the contention approach for LANs, such as CSMA/CD, is the capacity wasted due to multiple stations attempting

sammy [17]

Answer:

The overview of the given problem is outlined in the following segment on the explanation.

Step-by-step explanation:

The proportion of slots or positions that have been missed due to numerous concurrent transmission incidents can be estimated as follows:

Checking a probability of transmitting becomes "p".

After considering two or even more attempts, we get

Slot fraction wasted,

= $[1-no \ attempt \ probability-first \ attempt \ probability-second \ attempt \ probability+...]$

On putting the values, we get

= $1-no \ attempt \ probability-[N\times P\times probability \ of \ attempts]$

= $1-(1-P)^{N}-N[P(1-P)^{N}]$

So that the above seems to be the right answer.

What is the measure of USQ pls help

zlopas [31]

Answer:

USQ = 227°

Step-by-step explanation:

∠ QPR = ∠ UPT = 47° ( vertical angles )

∠ QPR is equal to the measure of the arc that subtends it , so

arc QR = 47°, then

arc USQ = arc USR + arc QR = 180° + 47° = 227°

Given that ABCD is a parallelogram and AB is parallel to CD, which of the following statements is false? (1 point)

brilliants [131]

Answer:

The correct option is;

Angle A and B are congruent

Step-by-step explanation:

The given parameters are;

Quadrilateral ABCD = Parallelogram

Side AB is parallel to CD

Therefore, we have for properties of a parallelogram

Opposite sides are parallel

Therefore, AB and CD are opposite sides

Opposite sides are congruent

Opposite angles are congruent, therefore ∠A and ∠C are congruent and ∠B and ∠D are congruent (depending on the orientation of side CD)

Consecutive angles are supplementary, therefore, ∠A and ∠B are supplementary angles and ∠C and ∠D are supplementary angles

Therefore, the statement which is false is Angle ∠A and ∠B are congruent.
