Answer:

377 meals

Step-by-step explanation:

If you choose to have all three courses, then there are 6 choices for the first course, 8 for the second, and 5 for the last, making a total of 6*8*5=240 different possible meals.

If you choose two courses, then there are 3 options. You can pick appetizer and main meal, which would give you 6*8=48 possibilities. You can pick main meal and dessert, which would give you 8*5=40 possibilities. Finally you can pick appetizer and desert, which would give you 6*5=30 possibilities. In total these are 118 different possible meals with two courses.

Finally, you could choose 1 course, which would give you 6+8+5=19 different meals.

In total, this is 240+118+19=377 meals

If c=g-4f, find trinomial that represents C when F=2x^2-5 and G=5x^2+x-3
Margaret [11]

Answer:

c = -3x² + x + 17

Step-by-step explanation:

c = g - 4f

f = 2x² - 5

g = 5x² + x - 3

c = (5x² + x - 3) - 4(2x² - 5)

c = 5x² + x - 3 - 8x² + 20

c = -3x² + x + 17

The height that a ball bounces varies directly with the height from which it is dropped. A certain ball bounces 30 cm when dropp
Akimi4 [234]

The ball will bounce 72 cm high if dropped from a height of 120 cm

<u>Solution:</u>

Given, The height that a ball bounces varies directly with the height from which it is dropped.  

A certain ball bounces 30 cm when dropped from a height of 50 cm.  

We have to find how high will the ball bounce if dropped from a height of 120 cm?

Now, according to given information,

When dropped from 50 cm ⇒ bounces 30 cm

Then, when dropped from 120 cm ⇒ bounces "n"  cm

Now by Chris cross method, we get,

\begin{array}{l}{n \times 50=30 \times 120} \\\\ {\rightarrow n=\frac{30 \times 120}{50}} \\\\ {\rightarrow n=\frac{3600}{50}} \\\\ {\rightarrow n=72}\end{array}

Hence, the ball bounces 72 cm high.

Usimov [2.4K]

Answer: 51

Explanation: The range of a data set is the difference between the largest number in the data and the smallest number in the data set which in this case is 54 - 3 of 51. So the range of this data set is 51.

It has been observed that the average number of traffic accidents requiring medical assistance on the Hollywood Freeway between
Vesna [10]

Answer:

0.184

Step-by-step explanation:

As the statistician consultant, I would have to calculate the chance of having 2 ambulances on the freeway at this hours and relay the message to the dispatcher.

Probability of having the need for 2 ambulances.

We will have a poisson distribution:

Lambda = 1

P(x=2) = e^-2*1/2!

= 2.71828^-1/2

= 0.368/2

= 0.184

I would tell the dispatch rider that the possibility that 2 ambulances would be required is 0.184.

Thank you
