Sergio039 [100]

Answer:

(b) tangible approximation of the product that often look and feel like the product

Step-by-step explanation:

"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.

Suppose the sample space for a continuous random variable is 0 to 400. If

Sever21 [200]

Answer:

P(72 ≤ x ≤ 400) = 0.82. Correct: C.

Explanation:

<u>Probability Distribution</u>

In any probability distribution, the total probability of the sample space must be 1.

Since the sample space is given as a random variable x that takes values from 0 to 400, then:

P(0 ≤ x ≤ 400) = 1

For any value of x:

If the sample space is divided into two parts like:

P(0 ≤ x ≤ 72) and P(72 ≤ x ≤ 400), then the combined probability must be 1:

P(0 ≤ x ≤ 72) + P(72 ≤ x ≤ 400) = 1

Or, equivalently:

P(72 ≤ x ≤ 400) = 1 - P(0 ≤ x ≤ 72)

P(72 ≤ x ≤ 400) = 1 - 0.18

P(72 ≤ x ≤ 400) = 0.82

A. The value 0.92 is not correct since does not match with the value 0.82.

B. The value 0.18 is not correct since does not match with the value 0.82.

C. This is the correct value. Correct Choice

D. The value 0.982 is not correct since does not match with the value 0.82.

What is the solution to this equation?

QveST [7]

Step-by-step explanation:

$10x - 15x + 5 = - 45 + 20 \\ or \: 10x - 15x = - 45 + 20 - 5 \\ or \: - 5x = - 45 + 15 \\ or \: - 5x = - 30 \\ or \: \frac{ - 5x}{ - 5} = \frac{ - 30}{ - 5} \\ or \: x = 6 \\ \\ therefore \: the \: value \: of \: x \: is \: 6.$

<h3> D. The value of X is 6. I hopes</h3><h3> it helps you ☺️.......</h3>

The figure below is made of two sizes of rectangular prisms one type of prism measures 3 inches by 6 inches by 14 inches. The ot

Anni [7]

The complete question in the attached figure

we know that
[volume of a prism]=L*W*H

<span>first type of prism measures 3 inches by 6 inches by 14 inches
</span>then
[volume first type of a prism ]=3*6*14----------> 252 in³

second type of prism measures 15 inches by 5 inches by 10 inches
then
[volume second type of a prism ]=15*5*10----------> 750 in³

[volume of the figure]=2*[volume first type of a prism ]+[volume second type of a prism ]

[volume of the figure]=2*252+750---------> 1254 in³

the answer is 1254 in³
