The most appropriate choice for probability will be given by:

Probability that the number of households in these 4 who own homes is exactly 4 = [tex]\frac{42}{455}[/tex]

What is Probability?

Probability of an event is the chance of occurance of that event.

Probability can be obtained by Number of favourable outcomes divided by the total number of outcomes

Probability varies from 0 to 1.

Here,

Total number of households = 15

No of households to be selected = 4

4 households can be selected from 15 households in [tex]15 \choose 4[/tex] ways

                                                                                      = [tex]\frac{15!}{(15-4)! \times 4!}\\[/tex]

                                                                                      = [tex]\frac{15!}{11! \times 4!}[/tex]

                                                                                       [tex]=\frac{15 \times 14 \times 13 \times 12}{1 \times 2 \times 3 \times 4}[/tex]

                                                                                       = [tex]1365[/tex] ways

Now,

Number of households who own homes = 9

4 households can be chosen from 9 households in [tex]9 \choose 4[/tex] ways

                                                                                  [tex]\frac{9!}{(9-4)! \times 4!}\\[/tex]

                                                                                = [tex]\frac{9!}{5! \times 4!}[/tex]

                                                                                [tex]=\frac{9 \times 8 \times 7 \times 6}{1 \times 2 \times 3 \times 4}[/tex]

                                                                                = [tex]126[/tex]

Probability that the number of households in these 4 who own homes is exactly 4 = [tex]\frac{126}{1365}[/tex]

We are given two box plots of a variable, for two different towns. Recall that the structure of a box plot is

where Q1 is the 25th percentile (or quartile 1), Q2 is the median and Q3 is the 75th percentile (or Quartile 3). This type of graphs tells us how the data is distributed, and more specially it can tell us how the data is spread across the different values the variable could take. So the way to analyze the spread from the graph is by considering the inter quartile range (IQR). This amount can be calculated by simply finding the difference between Q3 and Q1. If this range is really small, this would mean that the data is less spread and if this range is big, then this would mean that the data is more spread.

Using the given box plots, we can determine the following:

Town A: Q3 = 40, Q1 = 20, IQR = 40-20=20

Town B: Q3 = 45, Q1=35, IQR = 45-35 = 10

So, this would lead to option D.

The measure of each angle are 36° and 144°

What is Supplementary angle?

Two angles are said to be supplementary if their sums total 180 degrees. A linear pair's two angles, like angles 1 and 2 in the illustration below, are always supplementary. But two angles don't have to be close to one another to be supplementary. In the following image, 3 and 4 are supplementary since their sums equal 180 degrees.

Let the provided angle be x, the supplementary angle be y.

y = x + 108 since x has 108° greater than y.

The total of the additional angles is 180°.

x + y = 180,

x + x + 108 = 180,

and x = 180 - 108.

2x = 72

x = 72/2

x = 36

Then,

y = x + 108

y = 36 + 108

y = 144

Consequently, the angles are 36° and 144°.

Answer: 6.809 < 6.812. 6.812 is greater.

Step-by-step explanation:

If you mean if...  

|-6.809| > |-6.812|

then, -6.812 will be bigger because when you absolute value an answer the number inside the | | will become positive. So the simplified equation will look like this:

The cost of a t-shirt is $25, the cap costs $20 and the stuffed animal costs $15

Let t-shirts be represented by x, the cap is represented by y and stuffed animals are represented by z

Items purchased by family:

4 t-shirts + 1 cap + 1 stuffed animal

The total cost of the items was = $135

Equation: 4x+y+z=135--------(1)

Items purchased by couple 1:

2 t-shirts + 1 cap + 3 stuffed animals

The total cost of the items was = $115

Equation: 2x+y+3z=115------(2)

Items purchased by couple 2:

2 t-shirts + 1 cap + 1 stuffed animals = $85

Equation: 2x+y+z=85------(3)

Subtracting equation (3) from (2) we get:

2z = 30

z = 15

Substituting the value of z=15 in equations (1) and (3) we get the following equations:

4x+y+15=135

4x+y=120------(4)

And, 2x+y+15=85

2x+y=70-------(5)

Multiplying equation (5) with 2 and subtracting equation (4) we get:

4x+y=120

y = 20

What is the Quadratic formula?

A second-degree equation is a quadratic equation. It implies that at least one term in which the variable is squared will be present. This equation's conventional form is:

ax²+ bx + c = 0

where a, b, and c are variables or coefficients.

X is also an unknowable variable.

The fact that the coefficient "a" cannot be 0 is one unbreakable law.

Two potential choices for its variable X will fulfill the equation because of the degree of 2. Quadratic equations may reflect a wide range of real-world scenarios, as is clear to observe. We'll now look at several solutions.

Quadratic is derived from the term "quad," which means square. Here, we'll create the formula for quadratic equations so that they may be solved.

The factorization approach fails to reduce a large number of equations. Such equations are solved using a more potent approach. Every quadratic problem may be solved using this technique. This is the formula for a quadratic equation in general.

This is how it is explained:

If ax2 + bx + c = 0, then

is a quadratic equation, then the following formula provides the value of x.

Simply enter the numbers for a, b, and c, and the computations will be performed.

The values of a, b, and c are extracted from the equation and entered into the quadratic equation formula.

A, B, and C in this case only numbers. These are the quadratic equation's numerical coefficients, which you must solve.

The number of mosquitoes will be increased by 5 inches of rain.

Maximum mosquito population = 25000

We are given the following in the question:

M(x) = 10x - x²

where M(x) denotes the number of mosquitos in millions and x denotes the amount of rainfall in inches.

To begin, we differentiate M(x) with respect to x, yielding

d(M(x)) /dx = d(10x - x²) /dx = 10 -2x

When we set the first derivative to zero, we get

d(M(x)) /dx = 0

10 - 2x = 0

x = 5

We get the same result when we differentiate M(x) with respect to x:

d²(M(x)) / dx² = -2

d²(M(x)) / dx² < 0

As a result of the double differentiation test, the maxima for M(x) occur at x = 5.

when the rainfall is 5 inches, the most mosquitoes are present.

Maximum mosquito population:

M(5) = 10(5) - (5)² = 25

As a result, the maximum number of mosquitos is 25000.

This probability of shipment being accepted is 84%.

And most similar deliveries will be allowed since the likelihood of receiving a sample with much more than three damaged batteries is extremely low.

If at least three batteries fail to satisfy standards, the delivery would be approved.

This may be described as a binomial distribution, with n = 54 samples as well as a p = 0.03 probability of not satisfying the parameters of any battery.

If n ≤ 3 the package will be accepted.

The probability of this event is:

P(D ≤ 3) = P(D = 0) + P(D = 1) + P(D = 2) + P(D = 3)

P(D = k) = (n! ÷ (k!(n-k)!)) × [tex]p^{k}[/tex] × [tex](1 - p)^{n - k}[/tex]

P(D = 0) = (54! ÷ (0!(54)!)) × [tex]0.03^{0}[/tex] × [tex](0.97)^{54}[/tex]

P(D = 0) = 1 × 1 × 0.110

P(D = 1) = (54! ÷ (1!(53)!)) × [tex]0.03^{1}[/tex] × [tex](0.97)^{53}[/tex]

P(D = 1) = 54 × 0.03 × 0.205

The number of breakfast Greg can eat from a box of cereal if he eats 1 1/2 servings for breakfast everyday is 8 breakfast.

Number of breakfast Greg can eat in a regular-sized box = A regular-sized box of cereal / servings of breakfast eaten everyday

= 12 ÷ 1 1/2

= 12 ÷ 3/2

= 12 × 2/3

= 24/3

= 8 breakfast

Cost of regular-sized box of cereal = $4.29.

Cost of one breakfast from a regular-sized box of cereal = Cost of regular-sized box of cereal ÷ Number of breakfast Greg can eat in a box

= $4.29 / 8

= 0.53625

Approximately,

$0.54 per breakfast

Number of breakfast Greg can eat in a family-sized box = A family-sized box of cereal / servings of breakfast eaten everyday

Therefore, the number of more servings of breakfasts Greg could eat from 1 family-sized box
