Answer:

He bought 5 tickets.

Step-by-step explanation:

The cost of buying t tickets is given by the following function:

$c(t) = 24.50t + 9.5$

If the student spent a total of $132 on tickets, how many tickets did he buy?

This is t when $c(t) = 132$ . So

$c(t) = 24.50t + 9.5$

$132 = 24.50t + 9.5$

$24.50t = 122.5$

$t = \frac{122.5}{24.5}$

$t = 5$

He bought 5 tickets.

The correct answer would be that Carl is 4 years old. If John is 20 years older than Carl, that would make him 24. 24 + 4 = 28 years. Therefore, Carl must be 4 years old.

Suppose the correlation coeffecient

Usimov [2.4K]

A relatively large correlation coefficient, such as the 0.87 given here, indicates a direct proportion relationship between two variables. Here, as baby gains weight, smart phone pricing increases. Note that this is NOT a causal relationship.
