Yesterday my family caught a largo fish. We ate 2/6 of the fish. Today we eat 2/4 of the fish. Told my motores that we ate more

Alchen [17]

Answer:

Step-by-step explanation:

Fraction of fish ate on first day = 2/6

fraction of fish ate on second day = 2/4

In case of comparison of rational numbers if the numerators of two rational numbers is same and the denominators are different, then the number having larger denominator is less than the number having smaller denominator.

So, the number 2/6 < 2/4

So, the fraction of fish ate on the first day is less than the amount of fish ate on te second day.

A forestry researcher wants to estimate the average height of trees in a forest near Atlanta, Georgia. She takes a random sample

marusya05 [52]

Answer:

The margin of error for her confdence interval is of 0.3757.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.99}{2} = 0.995$ . So we have T = 2.8982
