Gnesinka [82]3 years ago
7 0

Answer:

AUB={1,2,4,5,7,9}

ANB={ }

Explanation:

AUB means that you have to combine all the element in each set whereas ANB is the set of similar elements in set A and set B. As there is no same elements in set A and set B therefore ANB will be called as null set.

MaRussiya [10]

What the sample suggests is that; the mean body temperature couldvery possibly bevery possibly be 98.6 °F.

<h3>What is the Confidence Interval?</h3>

For a 99% Confidence Interval and DF = 103 - 1 = 102, the value of z = 2.33.

The formula for confidence interval is;

CI = x⁻ ± z(σ/√n))

We are given;

Sample mean; x⁻ = 98.9

standard deviation; σ = 0.67

sample size; n = 103

Thus the confidence Interval is;

CI = [98.9 - 2.33(0.67/√103)], [98.9 + 2.33(0.67/√103)]

CI = (98.9 - 0.154, 98.5 + 0.154)

CI = (98.36, 98.64)

Thus, 98.6 is contained within the 99% CI,and so we can conclude that the the mean body temperature could very possibly bevery possibly be 98.6 °F.

What do implicit bias or racism have to do with peanut butter and jelly?
Mariulka [41]
The only way I would think is that when making a PB&J the jelly and peanut butter are on separate breads showing that division between races. But, when you put the two sides together they are supposed to taste better together than alone which might symbolize that when races come together they are better together than seperate.
