Answer:
x ≤ -18. I hope this helps
Step-by-step explanation:
Answer:
A) Miguel: d=25t+10
gabby: d=30t
B) gabby will catch up with Miguel in 2 hours at a distance of 60 miles
Step-by-step explanation:
<u><em>Lets start of with the equation:</em></u>
There is 2 possible equations we can use for this:
- A) Miguel: d=25t+10 gabby: d=30t OR
- D) Miguel: d=10t+25 gabby: d= 30t
The resonable response for this would be A because Miguel starts off with 10 miles so you would add 10 to your equation so response D is incorrect because you are not multiplying 10t, but rather 25t.
<u><em>Now let's do the actual answer</em></u>
There is 2 possible answer for this:
- B) gabby will catch up with Miguel in 2 hours at a distance of 60 miles
- C) gabby will catch up with Miguel in 1.25 at a distance of 37.5 miles
The response that would make the most sense would be B. Let me explain
We are going to be using response C for now. You would have to multiply Miguel: 25(1.25) + 10
31.25 + 10
=41.25
Gabby: 30(1.25)
= 37.50
Miguel is still ahead of Gabby so Answer C is incorrect
We are going to be using response B now. You would have to multiply
Miguel: 25(2) + 10
50 + 10
=60
Gabby: 30(2)
=60
Now they are both the same mile so this would mean Answer B is correct

Answer:
hello your question is incomplete attached below is the complete question
answer :
a ≈ - 136
b = 2.46
Step-by-step explanation:
A) we apply the formula for slope in regression
b = r * 
--------- ( 1 )
where:
standard deviation (Sy) = 27.8913
standard deviation ( Sx ) = 11.2921
Linear correlation coefficient ( r ) = 0.9972
substitute given values into equation 1
b = 2.46
for intercept A
a = Y - b * X --------- ( 2 )
Mean number of ice bags sold ( Y )= 70.2873
b = 2.46
Mean temperature ( X )= 83.8959
substitute given values into equation 2
a = 70.2873 - ( 2.46 * 83.8959 )
= - 135.997
