Which of the following is the result of expanding 4 £ n=1 (2n-3)
geniusboy [140]

Answer: 8

Step-by-step explanation: the given expression is 2n-3

so when n=1, we will get, 2(1)-3=2-3=-1

when n=2, we will get, 2(2)-3= 4-3=-1

when n=3, we will get 2(3)-3= 6-3=3

when n=4, we will get 2(4)-3 = 8-3=5

so the required result of expansion is -1+1+3+5=8

answer is 8.

hope that helped!

Likurg_2 [28]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

The missing data is defined in the attached file please find it.

Given:

                                            Admission Status

\left\begin{array}{ccccc}Ethnography &Acceptable \ Approval &Waitlisted & Turned \ Away & Total\\\\ Hispanic/ Black & 51  &206&143 & 400 \\Asia &57&289&100&446\\White&                62&222&145&429\\ Total & 170& 717& 388& 1275\end{array}\right \\\\\\

In point A:

The overall percent of applicants, which is Asia:

= \frac{446}{1275} \\\\ = 0.3498039 \approx 34.98 \%

In point B:

The overall percent of the students, who admitted to Asia:

P(accepted\  Asian) = P( \frac{Placcepted \ Asian}{Asian})

                              =  \frac{\frac{57}{1275}}{\frac{446}{1275}} \\\\=  \frac{57}{1275} \times \frac{1275}{446} \\\\=  \frac{57}{446} \\\\= 0.1278027\approx 12.78 \%

In point C:

The Asian percentage approved:  

P(Asian/accepted) =\frac{P(accepted, Asian)}{P(accepted)}\\

                                =\frac{\frac{57}{1275}}{\frac{170}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{170} \\\\= \frac{57}{170} \\\\= 0.3352941\approx 33.52%

In point D:

The number of all students admitted:

=\frac{170}{1275}\\\\= 0.13333 \\\\= 13.33%

aev [14]
The bicycle costs $30 and Hugo finishes paying after 15 weeks. When he has paid for the bike, y=0 because he owes nothing. So -10=-2x+20, 2x=30, x=15. And the cost of the bike is 2×15=$30.
