Answer:
=−1/2
Step-by-step explanation:
- How can you write a system of equations to model this situation?
Let y = <span>your pay </span>
<span> x = deliveries
</span>
Your equations would be written as:
<span>y=9.50*4 </span>
<span>y=2*4+3x </span>
- Which method should you sue to solve the system?
Substitution method
- How can you interpret the solution in the context of the problem
Substituting y for 9.50*4:
<span>9.50*4 = 2*4 + 3x </span>
<span>Simplifying: </span>
<span>38=8+3x </span>
<span>Solving: </span>
<span>30=3x </span>
<span>x=10
</span>
<span>Therefore, you need 10 deliveries to get the same pay as the competitor.</span>
Fractions are useful for constant of proportionality, ratios, and just simplifying decimals. Ratios are good for recipes
Answer:
B.No. It describes the midrange, not the median.
Step-by-step explanation:
Further,
The range is the difference between the least and largest value of data. It measures skewness using all data points.
Mean is calculated as the ratio of the sum of all the observations to the total number of observations.
Median is the middle value of the data after arranging them in ascending order.
Answer:
5 guests: 6 slices 10 guests: 3 slices 15 guests : 2 slices
Step-by-step explanation:
So, we have 30 slices of pizza and 5, 10, and 15 slices
So , we need to divide 30 by each of the guests
30÷5=6
30÷10=3
30÷15=2
We can also heck by multiplying teh guests by our answer
5*6=30 ✔️
10*3=30✔️
15*2=30✔️
So, for 5 guests, each oione gets 6 slices
For 10 guests, each guest gets 3 slices
For 15 guests, each guest gets 2 slices
