Hello!

First, "the difference" of 2 numbers means you subtract these numbers.

Then, 4 cubed is written as follows:

4³

Subtract:

4³-25

[If necessary] Evaluate:

64-25

Hope everything is clear.

A sample of 1700 computer chips revealed that 51% of the chips do not fail in the first 1000 hours of their use. The company's p

Answer:

The answer is -1.2

Step-by-step explanation:

Recalling the standard deviation formula,

we have : σ = sqrt[ P * ( 1 - P ) / n ]

Where sqrt = square root

n = Number of derivative

Therefore,:

if, H0: p is not 48% vs H1: p1 = 48%

standard deviation is:

σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+ z -score is (p-P)/σ

= (.51-.53)/.01666333

The answer therefore = -1.2

ICONCLUSION:

It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.

a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?

viktelen [127]

Answer:

The area of the right triangle is 100 centimeters squared.

Step-by-step explanation:

The formula for the area of a right triangle is:

$Area = \frac{a*b}{2}$

Area = (a*b) / 2

The height of a triangle is represented by a. The base is represented by b.

Knowing this, we can use what they give us for the values, by plugging them into the formula.

a is 20 cenimeters

b is 10 centimeters

Therefore :

$Area = \frac{200}{2}$

$Area = 100$

So, the area of the right triangle is 100 centimeters squared.
