Nat2105 [25]

Answer:

The percentage change from 300 to 375 is 25 %

Step-by-step explanation:

((y2 - y1) / y1)*100 = your percentage change

((375 - 300) / 300) * 100 = 25 %

Suppose the test scores of students in a class are normally distributed with a mean of 86 and a standard deviation of 4. What is
WARRIOR [948]

Answer:

-2.5

Step-by-step explanation:

Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test

To calculate the z-score, we need to use a mathematical formula

Mathematically;

z-score = (x - mean)/SD

From the question;

x = 76

mean = 86

standard deviation SD = 4

Plugging these values in the equation, we have;

z-score = (76-86)/4 = -10/4 = -2.5

How many triangles can be constructed with angles measuring 120°, 40°, and 10°? one more than one none

pogonyaev

Answer:

f'(n) = n + 3

Step-by-step explanation:

Given

f(n) = n - 3

Required

The inverse

f(n) = n - 3

Replace f(n) with y

y = n - 3

Swap positions of y and n

n = y - 3

Make y the subject

y = n + 3

Replace y with f'(n)

f'(n) = n + 3
