Answer 1

Answer:

The value of X=37

hope this helps :)

X= 12^2 + 35^2

= √1369

= 37

Answer 2

Answer:

Answer:

Step-by-step explanation:

Pythagorean Theorem: a²+b²=c², with a and b being the 2 shortest sides of the triangle, and c being the longest.

a² b² c²

12² + 35² = 1369

Once you have c², you need to find the square root of c² to get c.

The square root of 1369 is 37. c=37

Assume that the given procedure yields a binomial distribution with n trials and the probability of success for one trial is p. Use the given values of n and p to find the mean mu and standard deviation sigma. Also, use the range rule of thumb to find the minimum usual value mu minus 2 sigma and the maximum usual value mu plus 2 sigma. In an analysis of preliminary test results from a gender-selection method, 33 babies are born and it is assumed that 50% of babies are girls, so equals 33 and p equals 0.5.

In January of 2003(group 1), 1188 out of 1500 spots were bare ground (no vegetation). Find the sample proportion of bare ground spots.

Answers

Answer:

$n= 1500$ represent the random sample selected

$X= 1188$ represent the number of pots that were bare ground (no vegetation

$\hat p=(X)/(n)$

And replacing we got:

$\hat p=(1188)/(1500)= 0.792$

So then the sample proportion of bare ground spots is 0.792 for this sample

Step-by-step explanation:

We have the following info given from the problem:

$n= 1500$ represent the random sample selected

$X= 1188$ represent the number of pots that were bare ground (no vegetation)

And for this case if we want to find the sample proportion of bare ground spots we can use this formula:

$\hat p=(X)/(n)$

And replacing we got:

$\hat p=(1188)/(1500)= 0.792$

So then the sample proportion of bare ground spots is 0.792 for this sample

Final answer:

The sample proportion of bare ground spots is calculated by dividing the number of bare ground spots (successes) by the total number of spots (sample size). Using this method, the sample proportion for this scenario is 0.792 or 79.2%.

Explanation:

The student has asked about finding the sample proportion of bare ground spots. In Statistics, one defines a sample proportion as the number of successes in a sample divided by the number of observations in that sample. In this case, the 'success' is finding a spot of bare ground.

The sample size here is the total number of spots observed, which is 1500 (group 1) and the number of successes is the number of bare ground spots, which is 1188.

To calculate the sample proportion, one uses the formula: p = x/n, where 'x' is the number of successes and 'n' the sample size. So, for this scenario the sample proportion (p) would be: p = 1188/1500 = 0.792.

So, the sample proportion of bare ground spots is 0.792 or 79.2% when expressed as a percentage.

A water lily is floating in a murky pond rooted on the bottom of the pond by a stem of unknown length. The lily can be lifted 2 feet over the water and moved 6 feet to the side. What is the depth of the pond?

Answers

The depth of the pond is 8 feet and this can be determined by using the Pythagorean theorem.

Given :

A water lily is floating in a murky pond rooted on the bottom of the pond by a stem of unknown length.
The lily can be lifted 2 feet over the water and moved 6 feet to the side.

The Pythagorean theorem can be used to determine the depth of the pound. The Pythagorean theorem according to the attached diagram is given by:

$\rm (BD)^2 = (BC)^2+(CD)^2$
