Answer:
Step-by-step explanation:
y = - 3x
-7ab-9a-4 because u have to combine like terms and then subtract if that makes any sense
Y = 3/2 t - 5/2 ; where t = 3
Substitute t by its value. the nearness of 3/2 to t denotes multiplication.
y = (3/2 *3) - 5/2
3 is a whole number. it is 3/1 in fraction form.
In multiplying fractions, simply multiply the numerator and the denominator.
y = (3*3 / 2*1) - 5/2
y = 9/2 - 5/2
Subtracting fractions: We can only subtract or add fractions if they all have the same common denominator. Since both fractions have 2 as denominator, we can proceed to subtracting its numerators.
y = (9-5)/2 *subtract numerators and place over the common denominator
y = 4/2 * simplify the fraction.
y = 2/1 or 2
Answer:
There is a 98% confidence that the true proportion of voters who have voted in the last presidential election lies in this interval.
Step-by-step explanation:
The confidence interval for estimating the population proportion is:

The 98% confidence interval estimate for the proportion of voters who claimed to have voted in the last presidential election was (0.616, 0.681).
The sample taken was of size, <em>n</em> = 1050.
<u>Interpretation</u>:
The 98% confidence interval (0.616, 0.681) for the proportions of voters who claimed to have voted in the last presidential election implies that the true proportion of voters who have voted lies in this interval with 0.98 probability.
Or, there is a 98% confidence that the true proportion of voters who have voted in the last presidential election lies in this interval.
Or, if 100 such samples are taken and 100 such 98% confidence interval are made then 98 of these confidence intervals would consist of the true proportion of voters who have voted in the last presidential election.
