Lexi has planted seeds in 3/5 of the garden. She used 1/2 pound of the seeds. How many pounds will she use for the entire garden

postnew [5]

Answer:

She will use 5/6 pound for the entire garden

Step-by-step explanation:

Here, we want to know the total number of pounds that will be used for the full garden.

Firstly, she used 1/2 or 0.5 pound for 3/5 of the garden, let the total amount of pound she will use for the full garden be x.

0.5 pound = 3/5 garden

x pound = 1 garden

x * 3/5 = 0.5 * 1

x * 3/5 = 0.5

3x/5 = 0.5

3x = 5 * 0.5

3x = 2.5

x = 2.5/3 or 5/6 pound

Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th

Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = $\frac{270}{500}$ = 0.54

Confidence level = 95%

now,

standard error, SE = $\sqrt{\frac{p(1-p)}{n}$

SE = $\sqrt{\frac{0.54(1-0.54)}{500}$

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]
