Two twin sisters, Gwen and Jackie, are both 20 years old in the year 2050. Jackie takes off on a round-trip to Vega, 25 light-ye
Contact [7]

Answer:

C. about 25 years.

Step-by-step explanation:

We have been given that two Jackie takes off on a round-trip to Vega, 25 light-years away. She travels at an average speed close to the speed of light, say, 0.9999c.

To find time it will take Jakie to reach Vega, we will divide the distance of Vega by Gwen's speed.

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

\text{Time}=\frac{25}{0.9999}

\text{Time}=25.00250  

\text{Time}\approx 25  

Therefore, it will take approximately 25 years for Jakie to reach Vega and option C is the correct choice.

<h3>Answer:</h3>
  • C. Dependent
<h3>Explanation:</h3>

When events are independent the probability of one does not depend on the other.

Here the probability of liking peas overall is 39%, but the probability of liking peas if you're male is 42%. That is, the probabilities are not the same, so the events are dependent.

_____

<em>Comment on answer choices</em>

Selections B and C are both "Dependent," so are correct in that aspect. However, the "reason" given for B has a bogus number (54%) for males liking peas. We have no idea where that number came from. C has the correct reason, so is the appropriate selection.

A taxi charges $7.50 plus $0.45 per mile.
poizon [28]
$7.50(2)=$15.00 (She takes the taxi twice, and its $7.50 each time she takes it)
$0.45(16)+$0.45(8)=$10.80 (Each mile is $0.45, she goes 16 miles on the way to work, and only 8 miles on the way home. Since she walks half way and  takes the taxi the other half. Half of 16 is 8)
$15.00+$10.80=$25.80
Alexis pays $25.00 per day for her taxi rides.
