Answer:
95% confidence for µ, the average number of times a horse races
(12.493 , 18.107)
Step-by-step explanation:
<u>Explanation</u>:-
The veterinarian finds that the average number of races a horse enters is 15.3
The mean of the sample x⁻ = 15.3
Given standard deviation of the sample 'S' = 6.8
Given sample size 'n' = 25
Degrees of freedom = n-1 =25-1 =24
The tabulated value 't' = 2.064 at two tailed test 0.95 level of significance
<u> 95% confidence for µ, the average number of times a horse races</u>
<u></u>

(15.3 - 2.80704 ,15.3 +2.80704)
(12.493 , 18.107)
<u>Conclusion</u>:-
95% confidence for µ, the average number of times a horse races
(12.493 , 18.107)
Answer:
7
Step-by-step explanation:

24^2+x^2=25^2
x^2=49
x=7
So, the missing side is 7.
Answer:
-128
Step-by-step explanation:
(-2)^2 * (-2)^5 <---
First, add the exponents
(-2)^7<----
If you evaluate this you will get
-128
Hence, the percentage increment is 33.25%
It goes zero positive negative. that is from left to right
