F(x) = 4x - 1

All you have to do is substitute the values in the domain for x in the function.

f(-1) = 4(-1) - 1
f(-1) = -4 - 1
f(-1) = -5

f(0) = 4(0) - 1
f(0) = -1

f(1) = 4(1) - 1
f(1) = 4 - 1
f(1) = 3

And so on.

A particular fruit's weights are normally distributed, with a mean of 405 grams and a standard deviation of 19 grams. If a fruit
cluponka [151]

Answer:

413.126

Step-by-step explanation:

Given a normal distribution :

Mean (m) = 405

Standard deviation (s) = 19

Weight of fruit will be greater than how many grams (x) if picked 17% of the time:

P(Z > x) = 0.17 ;

The Zscore for P(Z > x) = 0.17 equals 0.954 (Z probability calculator)

Zscore = (x - m) / s

0.954 = (x - 405) / 19

0.954 * 19 = x - 405

18.126 = x - 405

x = 18.126 + 405

x = 423.126

Weight will be greater than 423.126

X=95°(right opposite angle)

As X is right opposite to 95°,meaning that it would be 95° as well.
Please do remember that any angles that are right opposite to each other would be equal.

Which expression gives the area of the triangle shown below?
kvasek [131]
The answer is d. The reason this is the answer is because to find the area of a triangle you will find half of the base times the height. The formula looks like this: A=1/2bh.

On this picture the base is the length of the bottom part of the triangle (c). It is the distance of the solid line only.

The height is represented as the straight line that is perpendicular to the base (forms a right/90 degree angle). X is the height of the triangle.

Therefore, 1/2cx is the answer.
