Answer:
x^2 +7x+12
Step-by-step explanation:
(x+3)(x+4)
FOIL
first x*x= x^2
outer: 4x
inner:3x
Last 3*4=12
Add together
x^2+3x+4x+12
Combine like terms
x^2 +7x+12
First, convert all fractions to the lowest common denominator: 20
It takes 5/20 of an hour to string bracelets and 2/20 of an hour to string them. Thus, it takes 7/20 of an hour to make one bracelet.
Megan has 5 and 4/20 hours, or 104/20 hours, to make bracelets. Here, we must divide 104/20 hours by 7/20 hours.
Really, it is dividing 104 by 7 since they have the same denominator. 104/7 is 14.86, so she can make 14 whole bracelets in 5 and 1/4 hours.
We don’t know the value for the population, so we must estimate the standard error using the data from the sample. Standard error = sqrt(p(1 - p)/n), where p is the proportion of yes and n is sample size. Margin of error = z* * standard error, z* = 1.64, so margin of error is 0.053. A sample size less than 10% of the population is needed to make an inference, thus, d is the correct answer. If this was confusing, please don’t hesitate to comment, hope this helps!
