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?

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.

Express the -0.345 in the form of p\q and reduce it to the lowest term

Mamont248 [21]

Answer:

-69/200

Step-by-step explanation:

-0.345 is in decimal form.

In Fractional form (p/q)

=-345/1000

To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.

In this case,G.C.D of 345 and 1000 is 5.

Simplified form=-69/200 [ANS]

What is the inverse function of y = √ x − 1 2 , x ≥ 1 2a. y=x2−14,x≥0 b. y=x2−12,x≥0 c. y=x2+12,x≥0 d. y=x2+14,x≥0

hammer [34]

The function is :

y = √(x-12), x≥12

To find the inverse function, we interchange x and y, and then make y the subject again.

So interchanging x and y we have:

x = √(y-12)

Squaring both sides gives;

x² = y-12

Now making y the subject we have,

y = x² +12

x≥0.

Therefore the inverse function is;

y = x² +12, x≥0.

Hence the correct answer is C.

The graph represents a distribution of data.

makvit [3.9K]

Answer:

Mean=50

Step-by-step explanation:

The mean of a probability distribution is a <u>measure of central tendency</u>,and gives information about how the possible values of x are distributed.

The vertical axis measures the probability of finding a specific value of x in the sample. The probability of finding a value near the mean is high (that is why the value of the function that is depicted in the vertical axis, increases as we get closer to the mean=50): this is because the mean is that value of x around which higher probability of occurrence is associated.

What’s 0.85 in simplest form

jek_recluse [69]

Answer:

17/20

Step-by-step explanation:

To find the simplest form of 0.85 you need to turn it into a fraction.

To turn it into a fraction you put 85 over 100 since 0.85 is in the hundredths place.

85/100 can be simplified to 17/20 because 85/5 is 17 and 100/5 is 20
