I think it’s the second one because The formula would be
x=

Well we're just looking at oil paintings so let's say each shows 2 paintings...
30/2 = 15
so at most- 15 artists
Answer:
Maximum walking speed of camel is 31.749V feet per second
Step-by-step explanation:
Walking speed of an animal is given by :
Speed = 5.7VI (in feet per second) where l is the animal's leg length.
For a camel, leg length is 5.7feet.
So maximum walking speed of camel will be:
Speed of camel = 5.7V * 5.7 = 5.7² V feet per second
Speed of camel = 31.749V feet per second
hence, maximum walking speed of camel is 31.749V feet per second
Answer:
i think it´s b
Step-by-step explanation:
Answer:
a) -1.25
b) 0.2112
c) -1.96
Step-by-step explanation:
Data provided in the question:
Sample size, n = 400
H0 : p = 20
= 175
Now,
a) The test statistic is given as:
Z = 
on substituting the respective values, we get
Z = 
= -1.25
b) The p-value = 2 × P(Z <-1.25)
Now from the standard normal table
P(Z <-1.25) = 10.56% = 0.1056
Thus,
p-value = 2 × 1056 = 0.2112
c) for a = 0.05,
the critical value is
i.e 
Now from standard normal table
= -1.96
