New value =

80 - Percentage decrease =

80 - (50% × 80) =

80 - 50% × 80 =

(1 - 50%) × 80 =

(100% - 50%) × 80 =

50% × 80 =

50 ÷ 100 × 80 =

50 × 80 ÷ 100 =

4,000 ÷ 100 =

40

That would be 40 because 50% would take away half

The slope of a line is -1/4 and the y-intercept is 8. Whats the x-intercept?
Fed [463]
Slope = -1/4
y-interept = 8
⇒equation:  y = -1/4x + 8

x-intercept ⇒ when y = 0
0 = -1/4x + 8
1/4x = 8
x = 8 x 4 
x = 32

What is the meaning of probability in math?

  • Probability is simply how likely something is to happen.
  • Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
  • The analysis of events governed by probability is called statistics.

Three Types of Probability

  • Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
  • Relative Frequency Definition
  • Subjective Probability.

Ares of a rectangular floor of your house is Ax+5x-2. if the length is x+2 units, find A​
Snezhnost [94]

Answer:

A=4.

Step-by-step explanation:

Note: In the expression of area the first term should be Ax^2.

It is given that area of a rectangular floor of your house is Ax^2+5x-2 and the length is (x+2) units.

We know that, area of a rectangle is

Area=length\times width

Since length of the rectangle is (x+2), therefore (x+2) is a factor of Ax^2+5x-2 and the value of Ax^2+5x-2 is 0 at x=-2.

A(-2)^2+5(-2)-2=0

4A-10-2=0

4A-12=0

4A=12

Divide both sides by 4.

A=4

Therefore, the value of A is 4.
