48 divided by 3 = 16
16 ounces of trail mix altogether in one bag.

Maslowich

Answer: 2285

Step-by-step explanation:

Formula to find the sample size is given by :-

n=p(1-p)(\dfrac{z_c}{E})^2

, where p = prior estimate of population proportion.

E= Margin of error.

z_c = z-value for confidence interval of c.

Given : Confidence interval : 95%

From the z-value table , the z-value for 95% confidence interval = z_c=1.96

The General Social Survey reported a sample where about 61% of US residents thought marijuana should be made legal.

i.e. the prior estimate of population proportion of US residents thought marijuana should be made legal : p=0.61  

 [∵ sample proportion is the best estimate for population proportion.]

Margin of error : E= 2%=0.02

Now, the required minimum sample size would be :-

n=0.61(1-0.61)(\dfrac{1.96}{0.02})^2

Simplify ,

n=0.2379\times9604=2284.7916\approx2285

Thus , we need to survey <u>2285</u> Americans .

Y - 11 = 3(x + 4)....distribute thru the parenthesis
y - 11 = 3x + 12....add 11 to both sides
y = 3x + 12 + 11...simplify

Peter has $100. The price of a watch is $60. If peter gets 25% discounts, can he buy 2 watches
slamgirl [31]
Do 60 divided by 4 ( 25 percent) which is 15. 60-15 is 45. 45 plus 45 is 90 so yes he has enough money to buy two watches
