Answer:

Without having any of the side lengths, we would only be able to identify a right angle if there is a small square in the corner of any of the angles. That would indicate a right angle and there for a right triangle.

With the side lengths, you can go by the pythagorean theorem or if side A and side B equal side C or the hypotenuse (the longest side, which is alway directly across from the right angle.)

A + B = C it would be a right angle.

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)

diana has z gerbils. jackie has 4 times as many gerbils as diana. if w stands for the number of gerbils jackie has, express w in

disa [49]

D=z, j=4d,

If w=j, then w=4d,

If w=4d and d=z then:

w=4z
