The missing side and angle of the similar polygons are as follows:

Similar polygons are two polygons with the same shape, but not the same size.

Similar polygons have corresponding angles that are congruent, and corresponding sides that are proportional.

Therefore, polygon ABCD is similar to polygon FGHI. This means the corresponding angles are congruent and the corresponding sides are proportional.

Therefore,

∠C is corresponding angle to ∠H. This means they are both congruent.

Hence,

∠H = 90 degrees

Let's find FI,

Sample space = 21

Pr(White or Yellow) = Pr(White) + Pr(Yellow)

Pr(White) = 3/21 = 1/7

Pr(White or Yellow)= 1/7 + 3/7 = 4/7

Answer:

200 in³

Explanation:

The lengths of the sides of the constructed tetrahedron are twice the length of the side of the small tetrahedron of 50 in³. It means that the scale factor for the solid is 2. So, the complete volume of the constructed tetrahedron is equal to

Vn = 2³(50 in³)

Vn = 8(50 in³)

Vn = 400 in³

However, we only use 4 small tetrahedrons, so the volume of these four solids is

4(50 in³) = 200 in³

Then, the volume of the gap is the difference between the volume of the constructed tetrahedron and the volume of the 4 small tetrahedrons

400 in³ - 200 in³ = 200 in³

So, the answer is 200 in³

Answer:  Denise spent more than Jane.

Step-by-step explanation:    Denise spent $9.97. We know now that Denise spent more than Jane. For the second part of the question how much more? We basically just subtract the two values. $9.97-$8.37 which is $1.60. There you go.

The required answer would be the inequality 4x + 2y ≥ 45, the graph has been attached which represents the given situation.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We have been given that the price for each bucket of popcorn was $4. The price of each drink was half the price of a bucket of popcorn.

The total amount of spend is $45

As per the given condition, the required inequality would be as

4x + 2y ≥ 45

The situation's representation is in the attached graph with labels for the intercepts.

Here y-axis represents the number of drinks, and the x-axis represents the number of buckets of popcorn.

Thus, the required answer would be the inequality 4x + 2y ≥ 45, the graph has been attached which represents the given situation.

The statements about the function that are true are

The equation of the graph is given as

f(x) = (x - 1)(x + 7)

The graph of the function is added as an attachment

On the graph, we have

Vertex = (-3, -16)

This is so because the graph has a minimum point of (-3, -16)

Also, the graph crosses the x-axis at x = 1 and x = -7

This means that the graph is positive at x >1 and x >-7

Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3

The question gives us the following function:

The X-intercept is where the function crosses the x-axis and the Y-intercept is where the function crosses the y-axis.

X-intercept:

Since the graph must cross the x-axis to have an x-intercept, we should equate f(x) to zero.

Y-intercept:

Since the graph must cross the y-axis to have a y-intercept, we should equate x = 0.

Answer

Thus, the x and y-intercepts are: x = 0 and y = 0 respectively

Step-by-step explanation:

The actual distance between the two cities in kilometers is 73.8 kilometers.

Given:

The distance between two cities on a map = 4.1 centimeters

The Scale used by the map is, 1 centimeter is equivalent to 18 kilometers.

To find the actual distance between the two cities in kilometers,

We know, 1 centimeter = 18 kilometers.

For converting the distance in centimeters to kilometers we multiply the value in centimeters by the value of 1 centimeter i.e.18 kilometers.

So, 4.1 centimeter = (4.1 × 18) kilometers

                              = 73.8 kilometers

Therefore, the actual distance between the two cities calculated in kilometers is 73.8 kilometers.

The difference quotient for the given function is:

[tex]-\frac{4}{x*(x + h)}[/tex]

For the function f(x), we define the difference quotient as:

[tex]\frac{f(x + h) - f(x)}{h}[/tex]

In this case, the function is f(x) = 4/x, replacing that in the general difference quotient:

[tex]\frac{4/(x + h) - 4/x}{h}[/tex]

Now we can simplify this to get:

[tex]\frac{4/(x + h) - 4/x}{h} = 4*\frac{1/(x + h) - 1/x}{h} \\\\4*\frac{1/(x + h) - 1/x}{h} = 4*(\frac{1/(x + h)}{h} - \frac{1/x}{h})[/tex]

[tex]4*(\frac{1/(x + h)}{h} - \frac{1/x}{h}) = 4*(\frac{1}{(x + h)*h} - \frac{1}{x*h}) = 4*\frac{x - x - h}{x*h*(x + h)} = -\frac{4}{x*(x + h)}[/tex]

(b) The probability that exactly 8 out of 12, 18 to 20-year-olds have not consumed an alcoholic beverage is 0.231991.

(c) The probability that at most two out of four randomly sampled 18 to 20 year old have consumed alcoholic beverages is 0.35.

(d) The probability that at least one out of four randomly sample 18 to 20 years has consumed alcoholic beverages is 0.99168.

The possibility of an event happening is defined by probability. We may need to forecast an event's result in a variety of real-world circumstances. The outcomes of an event may be certain or uncertain to us.

Given that 69.8% of people of 18-20 yr old consume alcohol.

Then p=0.698

Now let X is the random variable denoting the number of people who drinks alcohol.

(a) Let the sample size, n = 12, p = 0.698

It can be seen that X follows a binomial distribution

Then,

P(X=4) = ¹²C₄p⁴(1-p)⁸

= 495 × (0.698)⁴(1-0.698)⁸

=495 × 0.2373 × 0.00006919

= 0.008127

(b) P(X=8) = ¹²C₈p⁸(1-p)⁴

= 12!/ (8!)(4!)(0.698)⁸(1-0.698)⁴

=495 × 0.05634344 × 0.0083181

= 0.231991

(c) Let sample size n=4

p= 0.698

Then,

P(X≤2) = P(X=0)+P(X=1)+P(X=2)

= ⁴C₀p⁰(1-p)⁴ + ⁴C₁p¹(1-p)³ + ⁴C₂p²(1-p)²

=1 × 1× 0.0083181 + 4× 0.698 × 0.0275 + 6× 0.4872 × 0.091204

=0.3516881

=0.35

(d)

For P(X≥1)= 1-P(X<1)

=1-P(X=0)

=1-⁴C₀ p⁰(1-p)⁴

=1-1 × 1 × 0.0083181
