X = number of times they rent a boat.
Members
Cost = 105 + 9.50x
Non-members because members don't have to pay the 105 so we gotta leave it out.
Cost = 14.75x
Now to determine whether the cost would be equal, we need to set the two equations equal to each other.
105 + 9.50x = 14.75x
Now solve for x
105 = 5.25x
20 = x

Answer: C
Step-by-step explanation: There are 9 cards. 3 are vowels. 3/9 reduces to 1/3
Step-by-step explanation:
H0: u = 150
H1: u ≠ 150
Total sum = 15933.24
N = 100
Mean = 15933.24/100
= 159.3324
σ² = 25954.03 - (159.3324)²/100
σ² = 556.213
σ = √556.213
σ = 23.8162
Testing hypothesis
t = (bar x - u)/ σ/√n
= 159.3324-150/23.8162/√100
= 3.91
We will have a p value of 0.02
0.0002 < 0.01
We reject null hypothesis at 1% level of significance
C. Mean = 159.3324
Se= 2.3936
Df = 100-1 = 99
Critical value at 0.01 = +-2.626
T = x-u/s.e
= -2.626 =( x -150)/2.3936
When we cross multiply and solve this
X = 143.714 for the lower tail
2.626 = (x-159)/2.3936
= 156.286 for upper tail.
We therefore reject H0 at
Bar X <= 143.71
Bar X >= 156.286
At 10%
Critical t = 1.660
-1.660 = (x - 150)/2.3936
Solving this ,
X =146.02 at the lower tail
1.660 = (x-150)/2.3936
X = 153.97
We reject H0 at
X<= 146.03
X>=153.97
Answer:
60%
Step-by-step explanation:
3/5 left x 100 = 60%
158 hot dogs will be prepared if 105 people show up
Step-by-step explanation:
14 people show up to make 21 hot dogs
We need to find how many hot dogs will be prepared if 105 people show up?
We will solve this problem using Unitary method
Solving:
14 people make hot dogs=21
1 person makes hot dogs = 21/14
105 people make hot dogs = 21/14*105
= 157.5 ≈ 158 hot dogs
So, 158 hot dogs will be prepared if 105 people show up
