Answer:
Step-by-step explanation:
in order to make a box plot you need to know 5 things.
the minimum, the first quartile, the median, the third quartile, and the maximum value. aka <em>the five number summary </em>
using your calculator you can find that in this set of values:
min = 1
Q1 = 2.5
med (Q2) = 3
Q3 = 5.5
max = 7
the box plot will look something like this:
Work backwards.
Start with z = 4.
Now deal with the middle equation
y + 3z = 11 Substitute z = 4 and solve for y
y + 3(4) = 11 Subtract 12 from both sides
y + 12 = 11
y + 12 - 12 = 11 -12 Combine terms on the left and right
y = - 1 Now use the top equation for x
z = 4 z still = 4
2x + 4(-1) +3(4) = 14
2x - 4 + 12 = 14 Solve 3z
2x + 8 = 14 Subtract 8
2x + 8 - 8 = 14 - 8 Combine
2x = 6 Divide by 2
x = 6/2
x = 3
Answer
x = 3
y = - 1
z = 4
Answer:
The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is 
Step-by-step explanation:
We are given:
Distance = 100 m
Time = 20 s
We need to find:
Speed
The formula used is: 
Putting values and finding the expression

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is

If you would like to find the sales necessary for the salesperson to earn at least 800 in one week, you can calculate this using the following steps:
s ... weekly sales
350 + 10% of sales >= 800
<span>350 + 10% of s >= 800
</span>350 + 10% * s >= 800
10/100 * s >= 800 - 350
1/10 * s >= 450 /*10
s >= 450 * 10
s >= 4500
The correct result would be: <span>weekly sales >= 4500.</span>
