1/2 (4r+6) what dose (4r+6) mean

Alisiya [41]

Answer: 5

This is because (4r + 6) means you take r and multiply that number by 4.

Because there is no number, r would equal one in this case.

4 • 1 is 4

4 + 6 is 10

This would give us 1/2(10)

Half of 10 is 5.

Therefore, the answer is 5.

Answer:

Step-by-step explanation:

Given that a survey was conducted that asked 1004 people how many books they had read in the past year.

Results are:

x bar =12.5

s = 16.6

n = 1004

Std error of sample = $\frac{s}{\sqrt{n-1} } =\frac{16.6}{\sqrt{1003} }\\=0.524152\\=0.524$

Since population std dev is not known t critical value can be used for confidence interval.

df = 1004-1 =1003

t critical = 1.96

Margin of error $= 1.96(std error) =1.027$

Confidence interval lower bound $= 12.5-1.027 = 11.473$

Upper bound $= 12.5+1.027 = 13.527$
