Answer:
35
Step-by-step explanation:
The 16 onion bagels are twice as many as plain bagels, so there were 8 plain bagels.
There were 4 more sesame bagels than plain bagels, so there were 12 sesame bagels.
Adam has 8 plain, 12 sesame, and 15 onion bagels left, for a total of 35 bagels left.
you can have 14 rows with 5 chairs in each row. 14x5=70. hope i helped
Answer
standard deviation
Explanation
Standard deviation is the measure of spread of data around the mean.
Mode is the most common value - which would be the mean in a normal-like distribution.
Median is the middle value when the data is ranked in ascending order (or descending even)
Skewness, is when the mode of the data falls behind the mean by a large margin.
An example is GDP, a few billionaires increase the number number and distort it, even though most people are of low or middle based income.
Answer:
There is no enough evidence to reject the claim using a level of significance of 5%
Step-by-step explanation:
Let p be the true proportion of homeowners in Omaha who own a lawnmower. We want to test
vs 
(two-tailed alternative).
We have a large sample of size n = 500 and a point estimate for p is 
. The test statistic is given by
where 
is the standard error of 
when 
is true. The observed value is 
= 1.4064 which comes from a standard normal distribution. Because we want to use a level of significance of 5%, our rejection region is RR={z | z < -1.96 or z > 1.96} where -1.96 and 1.96 are the 2.5th and 97.5th quantiles respectively. Because 1.4064 does not belong to RR, we fail to reject the null hypothesis.
