Answer:

The student's z-score will not change

Explanation:

Z-scores are used to compare results of an individual or entity to the average population's scores.

Since the adjustment of additional points is added to each class member's score, the adjustment will shift the entire distribution of scores. However, there will not be a change in the relative position of the student's score in the class. As a result, the student's z-score will not change.

Can you guys please help me!!!
Dimas [21]

Answer:

x=6

Step-by-step explanation:

When we multiply exponents with the same base we add the exponents

When we divide exponents with the same base we subtract the exponents

4^3 * 4^3 ÷4^3 *4^3

We will work from left to right

Multiply means add

4^(3+3) ÷4^3 *4^3

4^6÷4^3 *4^3

Now divide means subtract

4^6÷4^3*4^3

4^(6-3)*4^3

4^3 *4^3

4^3*4^3

Multiply means add

4^(3+3)

4^6

4^6 = 4^x

The bases are the same so the exponents must be the same

x=6

A rectangular lawn is 65 m long and 34 m wide. Over time, people have walked along a diagonal as a shortcut and have created a s
irina [24]
To calculate the length of the diagonal, use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the diagonal.
c^2 = 65^2 + 34^2
c^2 = 4225 + 1156
c^2 = 5381
c ~ 73.36
To the nearest tenth of a meter, the diagonal has a length of 73.4 m
