It would be 41 because its m math
The group paid $ 5250 at first city and $ 6250 at second city
<u>Solution:</u>
Let x = the charge in 1st city before taxes
Let y = the charge in 2nd city before taxes
The hotel charge before tax in the second city was $1000 higher than in the first
Then the charge at the second hotel before tax will be x + 1000
y = x + 1000 ----- eqn 1
The tax in the first city was 8.5% and the tax in the second city was 5.5%
The total hotel tax paid for the two cities was $790
<em><u>Therefore, a equation is framed as:</u></em>
8.5 % of x + 5.5 % of y = 790

0.085x + 0.055y = 790 ------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 1 in eqn 2</u></em>
0.085x + 0.055(x + 1000) = 790
0.085x + 0.055x + 55 = 790
0.14x = 790 - 55
0.14x = 735
<h3>x = 5250</h3>
<em><u>Substitute x = 5250 in eqn 1</u></em>
y = 5250 + 1000
<h3>y = 6250</h3>
Thus the group paid $ 5250 at first city and $ 6250 at second city
D) 3x + 30 = 150, hope this helps!
Solution :
a). The probability that the student will
the 1st question after the 4th attempt.
P (correct in the 4th attempt)
= 
= 0.01171875
b). The probability that the student will
3 questions after 10 total attempts.
P( X = 3) for X = B in (n = 10, p = 0.75)
= 
= 0.0031
c). The mean and the standard deviation for the number of attempts up to when the students gets all the questions correct is :
There are = 6 success, p = 0.75.
Therefore, this is a case of a negative binomial distribution.


= 8
So, 

= 1.6330
Answer:
inverse variation
Step-by-step explanation:
direct variation
y =xk
inverse variation
xy =k
Lets see if the data fits either
(4,25) and (5,20) and (10,10) are three points
direct variation
y/x = k which is a constant
10/10=1 does not equal 20/5=4 so it cannot be direct variation
inverse variation
xy =k
4*25 =100 5*20 =100 10*10 =100
This is a constant so it is inverse varaiton
