A class is organizing a going away party for one of their students. They spend $26.38 on decorations, $78.92 on food, and $34.50

Serjik [45]

Answer:

$9.35

Step-by-step explanation:

Simply start by adding up the total cost of each item.

$26.38 + $78.92 + $34.50

= $140.25

The total is $140.25

If 15 students want to split the cost, you’ll need to divide it by 15.

$140.25 divided by 15 = $9.35

So the total for each student is $9.35

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 15 minute

madam [21]

Answer:

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformly distributed between 3 minutes and 15 minutes:

So $a = 3, b = 15$

What is the probability that it takes Isabella more than 11 minutes to wait for the bus?

Either she has to wait 11 or less minutes for the bus, or she has to wait more than 11 minutes. The sum of these probabilities is 1. So

$P(X \leq 11) + P(X > 11) = 1$

We want P(X > 11). So

$P(X > 11) = 1 - P(X \leq 11) = 1 - \frac{11 - 3}{15 - 3} = 0.3333$

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus

Which equation correctly shows how to determine the distance between the points (9, –2) and (6, 3) on a coordinate grid?

nalin [4]

Answer:

The formula for calculate the distance (d) between two points is: Given the points (9,-12) and (6,3), you can identify: Substitute these coordinates into the formula to find the equation that correctly shows how to determine the distance between the given points (9,-12) and (6,3)
