Your favorite breakfast cereal contains a toy dinosaur in each box. There are four different dinosaur toys in the complete colle

ction, and each one has an equal chance of being in each box.
You want to figure out what the probability is that you will get more than one tyrannosaurus rex if you buy five boxes of cereal. Which experiment could be used to simulate this situation?
A) You flip a coin 5 times and record the number of times you get tails. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more tails.
B) You draw 5 cards from a deck of cards and record how many spades you get. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more spades.

C) You spin a 5-color spinner 4 times and record how many times you get a blue. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more blue spins.
D) You put 5 different colored marbles in a bag. You draw 4 marbles out and record how many are red. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more red marbles.

Answer:

(D) 30 degrees

Step-by-step explanation:

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.

<u>Theorem(Inscribed Angles Conjecture I): </u>In a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.

By the theorem above and from the attached diagram,

Inscribed Angle p =Half of 60 degrees

\angle p=0.5 X 60^\circ\\p=30^\circ

<u>The correct option is D.</u>

Which of the following is an even function? A.f(x) =(x-1)^2 b. F(x)=8x c.f(x) =x^2-x d.f(x)=7
pentagon [3]

Answer:

Step-by-step explanation:

A.f(x) =(x-1)^2  is even because of that even exponent, 2.

b. F(x)=8x  is odd because x has the exponent 1.

c.f(x) =x^2-x   is neither even nor odd

d.f(x)=7    is even because the exponent is even:  7^0

NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW!!!!
Over [174]

9514 1404 393

Answer:

  b.  -150

Step-by-step explanation:

We usually take elevation to be positive above sea level, and negative below sea level. If the elevation is below sea level, it is negative. If it is within 200 ft of sea level, the magnitude of the negative number is 200 or less. That is, the elevation must satisfy ...

  -200 ≤ elevation < 0

The only answer choice in that range is -150.

Ethan's elevation in feet could be -150.
