Mashutka [201]

Answer:

0.1601 to the nearest ten thousandth.

Step-by-step explanation:

This = Number of vehicles with a Bristol tag / Total number of cars.

= 1863 /  11637

If a is directly proportional to b, and a = 25 when b = 35, find b when a = 40
koban [17]

If a is directly proportional to b, we have the relationship to be:

\begin{gathered} a\propto b \\ \therefore \\ a=kb \\ where \\ b=constant \end{gathered}

When a = 25, b = 35. Therefore, we can calculate the value of k as follows:

\begin{gathered} 25=35k \\ k=\frac{25}{35} \\ k=\frac{5}{7} \end{gathered}

Therefore, the relationship is given to be:

a=\frac{5}{7}b

When a = 40, we can calculate the value of b to be:

\begin{gathered} 40=\frac{5}{7}b \\ 40\times7=5b \\ 5b=280 \\ b=\frac{280}{5} \\ b=56 \end{gathered}

The value of b is 56.

Megan picks a card from a deck of cards numbered 1-10 and rolls a number cube. What is the probability she chooses a card with a
ehidna [41]

Answer:

1/20 if there is only those 10 cards in a deck and 1/26 if there is 52 cards in the deck.

Step-by-step explanation:

There is 3/6 chances to roll a die with an even number, aka 1/2. If there are only 10 cards in the deck and only one of them has the number 5, it's 1/10. To find the probability of both these things happening, multiply the probabilities. 1/10 x 1/2 is equal to 1/20. However, since the question doesn't specify if there is 52 cards like a normal deck and 4 5's etc, there can be a different answer because if there's 52 cards in a deck, 4 of them 5's, the chance of getting a 5 is 4/52 or 1/13 and then you multiply that by 1/2 to get 1/26
