answer:

1. yes

2. no

3. yes

4. no

step-by-step explanation:

  • for 1, yes because no matter what they are the signs are still the same
  • for 2, no because the signs have changed — 2/5 is positive now
  • yes because even though there is addition now, the signs are the same. when you use kcc (keep change change), the sign changes to +
  • no, because the coefficient for p is changed, which won't be true or give us the same result

A 6-sided die with sides numbered 1 through 6 is tossed. A penny is then tossed. If the penny comes up heads, the value of the d
Montano1993 [528]

Answer:

The probability that the outcome is less than 6 is 58.333%.

Step-by-step explanation:

Since a 6-sided die with sides numbered 1 through 6 is tossed, ya penny is then tossed, and if the penny comes up heads, the value of the die is multiplied by 2, but otherwise, the value of the die is left unchanged, to determine what is the probability that the outcome is less than 6 the following calculation must be performed:

(5/6 + 2/6) / 2 = X

(0.8333 + 0.0333) / 2 = X

1.1666666 / 2 = X

0.583333 = X

Therefore, the probability that the outcome is less than 6 is 58.333%.

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?
victus00 [196]

Answer: Choice C.  p = 250(0.79)^t

Work Shown:

p = a*b^t

p = a*(1+r)^t

p = 250*(1+(-0.21))^t

p = 250(0.79)^t

Note that r = -0.21 is negative to indicate we have exponential decay.

6. In a standard deck of cards:
Dafna11 [192]

Events A and B are dependent (option B).

<h3>What are dependent events?</h3>

Dependent events are events that can occur together. If event A occurs then event B would occur. In a standard deck of cards, cards that are hearts are red in colour. If a heart card is picked, then it would be red in colour.

Independents events are events whose occurrence do not depend on each other. They are random events.
