Answer:

133

Step-by-step explanation:

Given is a cyclic quadrilateral ABCD.

We know that in a cyclic quadrilateral, opposite angles are supplementary.

A+C =180

Given that A = 4x+5 and C = x+15

Add these and equate to 180

4x+5+x+15 =1805x=180-20 =160x=32A= 4(32)+5 =133

Verify:

When x= 32, Angle C = 47

A+C = 133+47 = 180

Hence right answer

Agent Bourne transferred classified files from the CIA mainframe into his flash drive. The drive had 3 6 . 5 36.536, point, 5 me
BaLLatris [955]
I'm not sure what the question is.

Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes

After 125 seconds, there were 549 megabytes on the drive.

549 - 36.5 = 512.5 megabytes is the weight of the transferred files.

512.50 megabytes / 125 seconds =  4.1 megabytes per second

The rate of transfer is 4.10 megabytes per second.

1000 - 549 = 451 megabytes free space.

451 megabytes / 4.1 megabytes per second = 110 seconds

It would take an additional 110 seconds to completely fill up the flash drive.

The weight of people in a small town in missouri is known to be normally distributed with a mean of 154 pounds and a standard de
ad-work [718]
If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:
z=\frac{173-154}{29}=0.655
Referring to a standard normal distribution table, and using z = 0.66, we find:
P(\bar x\ \textless \ 173)=0.7454
Therefore
P(\bar x\ \textgreater \ 173)=1-0.7454=0.2546
The answer is: 0.2546
