So if you have 9 cats and they each have 9 kittens, then a reasonaable estimate is 10 times 9 since 10 is close to 9 so that is 90 and the answer is 81
you would knwo if you got 988387479 kittens if you got a problem because that is nowhere close to 90

and who do you call? ghostbusters!

nata0808 [166]

Answer:

233.35488 km (Rounded to 233 km)

Step-by-step explanation:

If you convert miles to kilometers then you would use this conversion factor:

1 mile = 1.609344 km (or 1.61 km)

so in this case,

145 mile = 1.609344 km x 145

145 mile = 233.35488 km

I could also round it to 233 km.

Since your on a trip... i hope u enjoy ur journey to Las Vegas!

mestny [16]

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.

The sum of two numbers is 45 . the smaller number is 9 less than the larger number. what are the numbers?
Cerrena [4.2K]
Larger Number: L
Smaller Number: L-9
Larger Number + Smaller Number = 45

L + L - 9 = 45
2L = 54
L = 54/2
L = 27

Smaller Number = L - 9
27 - 9 = 18

Check. .. 27 + 18 = 45. CORRECT!

Larger Number is 27
Smaller Number is 18
