Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.
grin007 [14]

Answer:

<u>D. </u>

<u>Mean: 24.8</u>

<u>Median: 26</u>

<u>Mode: 26</u>

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

<u>Mean: 24.8</u>

<u>Median: 26</u>

<u>Mode: 26</u>

<u></u>

A nonsense mutation in a gene _____. A nonsense mutation in a gene _____. has no effect on the amino acid sequence of the encode
Delicious77 [7]

Answer:

introduces a premature stop codon into the mRNA

Explanation:

A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.

There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.

11. What is speed?
Harrizon [31]

11. In everyday use and in kinematics, the speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

12. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector. In its simplest form, average velocity is calculated by dividing change in position (Δr) by change in time (Δt).

13. Here we will learn the mathematical relation between the speed, distance and time. The speed of a moving body is the distance travelled by it in unit time. If the distance is in km and time is in hours, then the speed is km/hr. If the distance is in m and the time is in seconds, then the speed is m/sec.

14. Average speed is the distance traveled divided by elapsed time. We have noted that distance traveled can be greater than displacement. So average speed can be greater than average velocity, which is displacement divided by time

15. Both have the same average speed, so neither is the fastest. (Please see the solution in the picture)

16. Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
