Find the measure of arc DC, in degrees, where the ? is shown. D ? 49° 70° с B​
bazaltina [42]

Answer:

m(arc CD) = 122°

Step-by-step explanation:

Since, measure of an arc = 2 × (Angle subtended by the arc at the circumference of the circle)

m(arc CD) = 2[m(∠CBD)]

By triangle sum theorem in ΔBCD,

m∠CBD + m∠BDC + m∠DCB = 180°

m∠CBD + 49° + 70° = 180°

m∠CBD = 180° - 119°

m∠CBD = 61°

Therefore, m(arc CD) = 2 × 61°

m(arc CD) = 122°

Choosing 8 marbles from a box of 40 marbles (20 purple, 12 red, and 8 green) one at a time with 18) replacement, keeping track o
elixir [45]
<h3>Answer: D) Not binomial: there are more than two outcomes for each trial. </h3>

Explanation:

Replacement is being done, so each trial is independent. However, the outcomes are values from this set {0,1,2,3,4,5,6,7,8} which represent the number of red marbles chosen. Since we do not have two outcomes, we do not have a binomial distribution. If instead you made the outcomes {red, not red}, then you would have two outcomes and it would be a binomial distribution.
