Answer:
The supplier becomes less accurate than they otherwise would have tried to claim. A further explanation is below.
Step-by-step explanation:
According to the provider, this same width of that same confidence interval would be as follows:
= 
= 
Depending on the input observed, the width including its confidence interval would be as follows:
= 
= 
As even the width of that interval again for survey asserted > the width including its confidence interval according to the provider's statement, we could conclude that such is the appropriate reaction.
90/300
To make it simpler, make it,out of 100 by dividing it all by 3. This will make it:
30/100
Therefore it is 30%
What is that ? are you joking ?
Answer:
1 hour and 45 minutes
and 1 hour
Step-by-step explanation:
x= run
y= walk
5x+2.5y = distance
5x+2.5(1.5)=12.5
solve for x
5x=8.75
x=1.75
1.75 in hours is 1 hour and (60*.75)=45
1 hour and 45 minutes
" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"
We use the same equation
5x+2.5y=distance
we'll assume that they till walked 12.5 miles
which means that
5(2)+2.5y=12.5
solve for y
2.5=2.5y
y=1
1 hour
For a line to be parallel, the slope has to be the same(1/3) only its coordonate on the y axis (b) changes.
Therefore the new equation will be y=1/3x+b
To find be, tou have to isolate it after inputting the new coordinates (-9,4)
(4)=1/3(-9)+b
4=-3+b
7=b
Therefore, the new equation is
y=1/3x+7
