Answer:

x=136 degrees

Step-by-step explanation:

A quadrilateral inscribed in a circle has opposite angles that add up to 180 degrees. So x + 44 deg = 180 deg. We can solve this to get x = 136 deg.

I hope this solution was helpful. Happy mathing!

For the simple random sample, drawn from a normally distributed population, value of 27, because it’s greater than 26. 7 and less than 29. 3.

<h3>What is normally distributed data?</h3>

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

Total number of sample is 60. The mean found to be 28, with a standard deviation of 5. The z-score is 1. 96.

The margin of error can be found out using the following formula as,'

MOE=z\times\dfrac{\sigma}{\sqrt n}

Put the values as,

MOE=1.96\times\dfrac{5}{\sqrt 60}\\MOE=1.2652

As, the mean of the sample is 28. Thus, the upper and lower limits are,

UL=28+1.2652=292625\\UL=28-1.2652=26.7348

Hence, For the simple random sample, drawn from a normally distributed population, value of 27, because it’s greater than 26. 7 and less than 29. 3.
