Maury = 120/10 (12 calls/hour)
Tyra = 120/8 (15 calls/hour)
Together they are 27 calls per hour.
120 / 27 = 4.4444444444
So it'd take them 4.44444444 (recurring) hours to make 120 calls.
Ok so R=alfonso's rate
w=wind rate=4
d=rt
with wind rate is R+4
agaoins wind rate is R-4
with wind distance is 34
against is 18 miles
time is same
34=(r+4)t
18=(r-4)t
34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t
18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t
18/(r-4)=t
34/(r+4)=t
set equal to each other
18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph
answer is 13mph with no wind
Answer:
NO
Step-by-step explanation:
Hello!
For this it's been made an ANOVA for four different variables, this means, in the null hypothesis there were four population means tested. When you reject the null hypothesis, you can assume that at least one of the GPA for the four majors is different. To know which one is different, or, if the GPA of finance students is different from the accounting students, you'll have to do an individual test between these two populations.
Hope you have a SUPER day!
10,740
Step-by-step explanation:
multiply by 3, because 4 x 3 equals 12, so that infers 3580 x 3, which equals 10,740
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of usage days
y ---> the total charge monthly in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
substitute
we have the ordered pair (13,41)
For x=13 usage days
therefore
That means----> Total charge in one month for 13 days of use is $41
