Mr. Walker is looking at the fundraiser totals for the last five years.
MrRissso [65]

1. If you want to find the mean you should add all fundraiser totals and divide it by number of years:

\text{ the mean }=\dfrac{896+925+880+963+914}{5} =915.6.

2. In order to find the median, firstly you have to order the fundraiser totals from the smallest number to the greatest number:

880, 896, 914, 925, 963.

The median is the middle number, then

\text{ the median }=914.

3. 915.6-914=1.6 - the mean is $1.60 greater than the median.

Answer: correct choice is B.

Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. How many cups, x,
siniylev [52]

Answer:

18 cups.

Step-by-step explanation:

We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: 20\leq 1.50x-6.50.

To find number of cups x to make a profit of at least  $20 we will use our given inequality.

20\leq 1.50x-6.50

20+6.50\leq 1.50x

26.50\leq 1.50x

x\geq \frac{26.50}{1.50}

x\geq \frac{53}{3}

x\geq 17.6666666

Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.

You go to an arcade and purchase a card with game credits. After playing 5 games you have 33 credits left. You play 4 more games
Amanda [17]

Answer:

y=-3x+48

Step-by-step explanation:

We will use slope-intercept form of equation to write our equation. The equation of a line in slope-intercept form is: y=mx+b, where m= Slope of the line, b= y-intercept.

To write the equation that represents the number of credits y on the cards after x games, we will find slope of our line.

We have been given that after playing 5 games we have 33 credits left. We play 4 more games and we have 21 credits left. So our points will be (5,33) and (9,21).

Let us substitute coordinates of our both given points in slope formula: m=\frac{y_2-y_1}{x_2-x_1},

m=\frac{21-33}{9-5}

m=\frac{-12}{4}=-3

Now let us substitute m=-3 and coordinates of point (5,33) in slope intercept form of equation to find y-intercept.

33=-3\cdot 5+b    

33=-15+b    

33+15=b    

48=b    

Upon substituting m=-3 and b=48 in slope-intercept form of an equation we will get,

y=-3x+48

Therefore, our desired equation will be y=-3x+48.
