Answer: Today is a true-false test.

Step-by-step explanation:

We know that the conclusion is the final statement on the basis the given statements or premises.

The given statements are :

A teacher gave all her classes a true-false test on seven consecutive Mondays.
Today is Monday.

If we assume that today is one of the seven consecutive Monday then the conclusion on the basis of the above statements will be :-

"Today is a true false test".

Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals

Alekssandra [29.7K]

Answer:

(0.767,0.833)

Step-by-step explanation:

The 95% confidence interval for population proportion p can be computed as

$p-z_{\frac{\alpha }{2} } \sqrt{\frac{pq}{n} }$

The z-value associated with 95% confidence level is 1.96.

whereas p=x/n

We are given that x=440 and n=550.

p=440/550=0.8

$0.8-1.96\sqrt{\frac{0.8(0.2)}{550} }$

$0.8-1.96\sqrt{\frac{0.16}{550} }$

$0.8-1.96\sqrt{0.00029 }$

$0.8-1.96(0.01706)$

$0.8-0.03343$

$0.76657$

Thus, the required confidence interval is

0.767<P<0.833 (rounded to 3 decimal places)

Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)

What is the simplified form of 5 square root x^4 • 5 square root x^4

laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

$\sqrt[5]{x^4}$ becomes $x^4^/^5$

When you multiply 2 terms with the same base, you add the exponents.

$x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5$

$x^8^/^5$ is also the same as $x\sqrt[5]{x^3}$

You get this because $\sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}$ . When you pull out 5 os x, you are left with x³ on the inside.
