Answer:
48.5 m/s
Step-by-step explanation:
291/6 = 48.5
-2 + 8 = 6
because if you have 2 negative circles ●● and 8 positive circles ○○○○○○○○ then once you take away the first two circles you get you answer. You do the opposite. :) ( hope that make sense... )
Answer:
p = 22.50 + 15t
Step-by-step explanation:
For Malik :
Membership fee = m
Rate per tournament = t
After 4 tournaments :
m + 4t = 85 - - - (1)
After 7 tournaments :
m + 7t = 130 - - - (2)
Subtract 2 from 1
4t - 7t = 85 - 130
-3t = - 45
t = 45 / 3
t = 15
Put, t = 15 in (1)
m + 4(15) = 85
m + 60 = 85
m = 85 - 60
m = 25
Massai pays 10% less membership fee than Malik
Hence, Massai's membership fee:
(100 - 10)% * 25
0.9 * 25 = $22.50
Total price, p, Massai will pay to compete in t tournaments ;
Total price = membership fee + (rate per tournament * number of tournaments)
p = 22.50 + 15t
Answer:
![\sqrt[5]{4}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B4%7D)
+ ![\sqrt[10]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%7D)
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as 
// use the ![a^{\frac{m}{n} } =\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
to transform the expression
Convert 
to ![\sqrt[5]{2^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B2%5E%7B2%7D%20%7D)
= (here a = 2, n = 5, m = 2)
Then convert 
to ![\sqrt[10]{3^{1} }](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%5E%7B1%7D%20%7D)
= (here a = 3, n = 10, m = 1)
Now we get = + . This is the simplified form, which is the answer.
Answer:
c. we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Step-by-step explanation:
Given that veterinary researchers at a major university veterinary hospital calculated a 99% confidence interval for the average age of horses admitted for laminitis, a foot disease that leaves the horse severely lame, as 6.3 to 7.4 years.
i.e. if X is the age of horses admitted for laminitis then the sample mean i.e. x bar follows a distribution with 99% confidence interval as
(6.3,7.4)
The interpretation of 99% confidence interval is the for sample of large size drawn at random from population we can be 99% confident that the sample mean will fall within this interval.
So the correct option is
c. we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
