Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8 7 cards

1st card :5

P(5) = number of 5's / total

= 1/7

Then we keep the card

Cards: 2,3,4,6,7,8 only 6 cards left

card less than 4: 2,3

P (card less than 4) = number of cards less than 4/ total cards

= 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

= 1/7 * 1/3

=1/21

Solve the inequality for –5.3 ≥ 6.7 + 4.3 + q

Tom [10]

Answer:

-16.3 ≥ q

Step-by-step explanation:

–5.3 ≥ 6.7 + 4.3 + q

Combine like terms

–5.3 ≥ 11 + q

Subtract 11 from each side

–5.3-11 ≥ 11-11 + q

-16.3 ≥ q

Evaluate 2(8 + t)3 – 6 when s = 3 and t = 2.<br><br> +) The value of the expression is 250

siniylev [52]

Step-by-step explanation:

s = 3 and t = 2

= 2(8 + t)³ - 6

= 2(8 + 2)³ - 6

= 2(10)³ - 6

= 2(1.000) - 6

= 2.000 - 6

= 1.994

Consider estimating a population proportion p. What is the most conservative sample size (erring on the large size) required in

just olya [345]

Answer:

The most conservative sample size is 2401.

Step-by-step explanation:

We are given the following in the question:

We are not given any approximation of s]ample proportion, thus,

$\hat{p} = 0.5$

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.5(1-0.5)}}{0.02}\\\\\sqrt{n}=49\\n = 2401$

Thus, the most conservative sample size is 2401.
