Answer:
The number of white horse to white horse is 9 : 31
Step-by-step explanation:
Given as :
The Total number of horses = 40
The number of white horses = 9
Let the number of black horses = x
So, x + 9 = 40
Or x = 40 - 9 = 31
∴ The number of black horses = 31
Now, The ratio of while to black horses = number of white horse : number of black horse
Or, number of white horse : number of black horse = 9 : 31
Hence The number of white horse to white horse is 9 : 31 Answer
Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20

Answer:
CI 98 % = ( 3.332 ; 5.668 )
t(c) = 2.9979
Step-by-step explanation:
Confidence Interval CI 98 % then α = 2 % α = 0,02 α/2 = 0.01
Sample information:
Sample size n = 8
sample mean x = 4.5
standard deviation of sample s = 1.1 kg
degree of freedom df = n - 1 df = 8 - 1 df = 7
With α/2 0.01 and df = 7 from t-studente table we find t(c)
t(c) = 2.9979
CI 98 % = ( x ± t(c) * s/√n )
CI 98 % = ( 4.5 ± 2.9979 * 1.1/ √8 )
CI 98 % = ( 4.5 ± 3.2976/2.8228 )
CI 98 % = ( 4.5 ± 1.168 )
CI 98 % = ( 3.332 ; 5.668 )
