From the given graph we can see that the graphical representation of the function has an open dot on -1. Hence, the function has no solution for f(-1).

An open dot on a number line graph denotes that the given number cannot be a solution, whereas a solid dot on the graph suggests that the supplied number should be considered as a potential solution. For instance, if you graph x > 7, you would put an open dot there because that is not a correct response (7 is not greater than itself).

If the builder does not build houses with three-car or more garages, then the probability that the buyer will select no garage home is 0.1.

Probability is a measure of likelihood that a certain event occurs. The probability of an event A is defined as:

P(A) = n(A)/n(S)

Where:

n(A) = number of ways the event A can occur

n(S) = number of all possible outcomes.

Suppose there are 3 possible outcomes, A, B, C, then:

P(S) = P(A) + P(B) + P(C) = 1

In the problem, let's define the events:

A = buyer will select a one-car garage

B = buyer will select a two-car garage

C = buyer will select no car garage

We have:

P(A) = 0.2

P(B) = 0.7

Hence,

P(A) + P(B) + P(C) = 1

0.2 + 0.7 + P(C) = 1

P(C)  = 1 - 0.9 = 0.1

A three-dimensional form's surface area is made up of the combined area of all of its faces.

The entire area of all the faces makes up the surface area of a three-dimensional form. We measure the area of each face and add them to determine the shape's surface area.

A 3D shape's volume is the interior area. An object's three-dimensional surface area is the sum of all of its faces. The formula Volume = length, width, and height is used to determine a cuboid's volume.

The volume of an object is the amount of three-dimensional space that the object or shape takes up.

A 3D object's surface area is the entire area that all of its faces cover. For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it. It is consistently expressed in square units.

A three-dimensional form's surface area is made up of the combined area of all of its faces. To calculate the surface area of the shape, we measure the areas of each face and add them.

Volume is the internal space of a 3D form. The total number of faces on an object determines its three-dimensional surface area. The volume of a cuboid can be calculated using the formula Volume = length, width, and height.

The quantity of three-dimensional space that an object or form occupies is known as its volume.

The total area that all of a 3D object's faces enclose is referred to as surface area. If we need to figure out how much, for example, the surface area of a cube is its surface area.

1. Total surface area of cuboid = 2(lb + bh + hl)

= 2(8×5 + 4×5 + 8×4)

= 2(92)

= 184 ft³

Total surface area of hollow cuboid = 2(1×5 + 4×5 + 1×4) = 58 ft³

Total surface area of given cuboid = 184 - 58 = 126 ft²

Volume of cuboid = l × b × h = 8 × 5 × 4 = 160 ft³

Volume of hollow cuboid = 1 × 4 × 5 = 20 ft³

Total volume of given cuboid = 160 - 20 = 140 ft³

2. Total surface area of cube = 6a² = 6 × 5 × 5 = 150 ft²

Total surface area of hollow cylinder = 2πr(r + h)

= 2 × 3.14 × 2 (2 + 5) = 87.92 ft²

Total surface area of cube given  =  150  - 87.92 = 62.08 ft²

Volume of cube = a³ = 5³ = 125 ft³

Volume of hollow cylinder = 2πrh = 2 × 3.14 × 2 × 5 = 62.80 ft³

Answer:

So today's % price at $21

Yesterday, the original 100% price was $16

Using a ratio

$16. 100%

------. =. --------

$21. x

Now we can cross multiply and divide

Cross multiplication gets you...

x = 2100/16

x = 131.25

Now to find the percent we subtract this from 100

131.25 - 100 = 31.25 which equals 31.3%

Quadrilateral CDEF is inscribed in circle A, so mARC CDE + mARC CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are _________________. So, _________________. Using the substitution property of equality, 2 ⋅ m∠CFE + 2 ⋅ m∠CDE = 360°. Using the division property of equality, divide both sides of the equation by 2, resulting in m∠CFE + m∠CDE = 180°. Therefore, ∠CFE and ∠CDE are supplementary.

The posterior predictive probability that if the die is thrown again, it will not show a six is 0.4

Probability is a mathematical concept that is used to describe the likelihood of an event happening.

In this case, the event is the result of throwing a six-sided die with an unknown number of faces marked with a six. This unknown number is referred to as k, and our prior distribution for k is given by

=> P(k = j) = -0.4 for j = 1 and 0.1 for j = 0, 2, 3, 4, 5, 6.

The normalized posterior distribution for k can be found by multiplying the prior distribution and the likelihood and then normalizing to ensure the sum of all probabilities equals 1.

The posterior mean for k is calculated as the weighted average of k, with the weights being the posterior probabilities.

Finally, the posterior predictive probability that if the die is thrown again, it will not show a six can be found by summing the probabilities of not getting a six for each possible value of k weighted by the posterior probabilities of k.

This gives us the overall probability that if the die is thrown again, it will not show a six.

Approximately 41 truck loads are needed to hold it.

Given that,

A builder is 243 cy backfilling. assuming each truck has a 162 cubic feet capacity

To find : What number of truckloads are required?

The quantity of trucks required serves as an example of rates.

There are 42 trucks required.

How to calculate the quantity of trucks

The backfill's size is specified as follows: 243 CY

A vehicle may carry as much as 162 CF.

The required number of trucks is then determined as follows:

n = 243 / 162

Convert n = 243 * 27 /162 from CY to CF.

Fix n = 40.5.

n is approximately 41.

The expected population in an additional 4 years is 15,125.

The expected population can be found by using the formula for uninhibited exponential growth.

Uninhibited exponential growth is modeled by the formula

P(t) = P₀ * e^(rt)

where P₀ is the initial population, e is the base of natural logarithms (approximately equal to 2.718), r is the growth rate, and t is the time elapsed.

We can first find the growth rate by using the formula

r = (ln(P/P₀)) / t

where P is the final population and t is the time elapsed. In this case, P₀ = 8000, P = 12000, t = 7 years, so we have:

r = (ln(12000/8000)) / 7

= 0.4055 / 7

= 0.0579

Next, we can use this growth rate to predict the population in an additional 4 years. Let t' = t + 4, so we have:

P(t') = P₀ * e^(r * t')

= 8000 * e^(0.0579 * (7 + 4))

Using a calculator, we can find that P(t') ≈ 15,125.

So, the expected population in an additional 4 years is approximately 15,125.
