-9x = -72

x = 8

  • 3y - 5x = -61

Find the following probabilities based on the standard normal variable Z. (You may find it useful to reference the z table
hammer [34]

Answer:

Step-by-step explanation:

a. P(Z > 1.12) = 1-N(1.12) = 1-0.8686431=0.1313569

b. <em>P(Z S-2.35)</em>  => P(Z <= 2.35) = 0.009386706

(please check interpretation of question b)

c. <em>POSZ s 1.34)</em> => P(0 <= Z <= 1.34) =  0.9098773 - 0.5 = 0.4098773

(please check interpretation of question c)

d. P(-0.8 sz s 2.44) => P(-0.8 <= 2.44) = 0.9926564 - 0.2118554 = 0.780801

(please check interpretation of question d)

There are two triangles in the figure(triangular prism) option third is correct.

<h3>What is a triangular prism?</h3>

When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is a name given to this novel 3D object.

The complete question is:

How many triangles are needed to draw the net of this object?

  • 4
  • 3
  • 2
  • 1

For the figure please refer to the attached picture.

As we can see in the figure we have given a triangular prism:

The triangular prism has two triangles.

A triangle for the base of the prism and a triangle for the top of the prism.

The lateral faces of the prism are rectangular.

Thus, there are two triangles in the figure(triangular prism) option third is correct.

Ln(x + 1) − ln(2) = 1
KonstantinChe [14]

Answer:

The answer to your question is: x = 4.44

Step-by-step explanation:

Data

                                          ln(x + 1) − ln(2) = 1

                                          In (x + 1)/2 = 1

                                          (x + 1) / 2 = e¹      

                                          x + 1 = 2 (2.7183)

                                          x = 5.44 - 1

                                          x = 4.44
