i own three dogs 5 cats 7 squirrels 8birds 10 lizards and 4 beetles I told my friends that my ratio of dogs+cats to my other pets is 8:37 but my friend says it is 8:29 Who is correct (if any) and if someone made a mistake what was the mistake

The friend is correct

Step-by-step explanation:

The ratio of dogs+cats to the other pets is 29. However the ratio of dogs+cats to the total number of pets is 8:37. Which they didn’t ask for, and ask for the ratio of dogs+cats to other pets.

Your friend is correct.

Step-by-step explanation:

You have 3 dogs and 5 cats; that makes [8] pets. Now, add up the rest of your pets (excluding dogs and cats, of course).

7 (squirrels) + 8 (birds) + 10 (lizards) + 4 (beetles) = [29] pets

[8:29]

By the looks of it, the mistake made here was adding up everything when calculating the second part of the ratio, including the dogs and cats (this shouldn't have been done).

Hope this helps, and have a good one.

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
