Answer:
1/169
Step-by-step explanation:
There are 4 aces in a deck of 52.
The probability that the first card is an ace is 4/52.
Since the card is replaced, the probability that the second card is an ace is also 4/52.
The total probability is (4/52) (4/52) = 1/169.
Answer:
k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
Answer:
Salamander trail is longer than great oaks trail.
Step-by-step explanation:
We have the data from two different maps of the same park.
In the first map the length of great oaks trail is 4.5 cm
The scale from the park to the map is 36 mi to 6 cm ⇒
We can find the real length of great oaks trail writing the following equivalence :
Where x is the real length of great oaks trail ⇒
We find that the real length of great oaks trail is 27 mi
In the second map the length of salamander trail is 3.5 cm
The scale from the park in the second map is 24 mi to 3 cm.
Again we can find the real length of salamander trail writing the equivalence :
Where y is the real length of salamander trail ⇒
We find that the real length of salamander trail is 28 mi.
Therefore salamander trail is longer than great oaks trail.
No Maria is wrong because if you look at placement value you would see 4 is in the one hundred thousands place.
