Answer:
1) m=-7/5
2) m=-7/5
3) parallel
Step-by-step explanation:
the first part:
graph the points and then find the slope
m=-7/5
the second part:
slope= m in y=mx+b
m=-7/5
the last part:
they are parallel because they have the same slope
Answer:
2
Step-by-step explanation:
I think below is your full question:
<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.
</em>
<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>
Here is my answer
Let x is number of shirts
Person COST
ERIN 12x+18
DAN 16x+10
Equally Billed 12x+18=16x+10 <=> x = 2
so each of them buy 2 shirts
Answer:
0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 49 minutes
Standard Deviation, σ = 16 minutes
We are given that the distribution of time an individual reads is a bell shaped distribution that is a normal distribution.
Formula:

P(no more than 30 minutes)

Calculation the value from standard normal z table, we have,

0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.
Answer:

Step-by-step explanation:
The given interval : x = 0 to x = 10
Length of interval = 10 - 0
= 10

⇒ Number of equal intervals = 5


Answer:
C = 15 + 20*p
Step-by-step explanation:
Cost for ordering = shipping and handling plus cost per part * number of parts
C = 15 + 20*p
