Farmer Gray has 30 flower pots. He plants 10 seeds in each pot. How many seeds does he plant?

Alex17521 [72]

Farmer Gray planted 300 seeds.

To find this, you simply multiply the number of flower pots (30) by the number of seeds in each pot (10). Thus making the answer 300.

I hope this helps!

Sonji has $5.25 in nickels and dimes . The coin value can modeled by the equation 0.10+0.05n=5.25, where d represents the number

Lyrx [107]

.10d + .05n = 5.25

.10(21) + .05n = 5.25

2.1 + .05n = 5.25

.05n = 3.15

n = 3.15/.05

n = 63

Answer:

The 90% confidence interval for the population proportion is

(0.10872, 0.19128)

Step-by-step explanation:

Explanation:-

Step(i):-

Given data A random sample of 200 e-mail messages was selected. Thirty of the messages were not business related

Given random sample size 'n' = 200

Given Thirty of the messages were not business related

let 'x' = 30

Probability of the messages were not business related or proportion

$p = \frac{x}{n} = \frac{30}{200} = 0.15$

Step(ii):-

The 90% confidence interval for the population proportion is

$(p - Z_{0.10} \sqrt{\frac{p(1-p)}{n} } , p + Z_{0.10} \sqrt{\frac{p(1-p)}{n} } )$

Level of significance ∝ = 0.90 or 0.10

The critical value Z₀.₁₀ = 1.645

The 90% confidence interval for the population proportion is

$( 0.15-1.645 \sqrt{\frac{0.15(1-0.15)}{200} } , 0.15 +1.645 \sqrt{\frac{0.15(1-0.15)}{200} } )$

on calculation, we get

(0.15 - 0.04128 , (0.15 + 0.04128)

(0.10872, 0.19128)

Conclusion:-

The 90% confidence interval for the population proportion is

(0.10872, 0.19128)
