As we can see from graph for given linear inequality -0.25≥-0.5x, the graph will be a number line with a closed circle on 0.5 with an arrow shaded right.

What exactly are linear inequalities?

Inequality is a mathematical statement in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers. The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.

The symbols "< and '>' represent severe inequalities, whereas  ‘≤’ and ‘≥’  represent slack inequalities. A linear inequality appears to be the same as a linear equation, however there is a difference.

Now,

Given linear inequality is -0.25≥-0.5x

0.25≤0.5x

1/4≤1/2x

x≥1/2

hence,

        graph will be a number line with a closed circle on 0.5 with an arrow shaded right.

The proof for the congruence of triangles GHI and GFJ are given below.

Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.

From the figure,

1) Line segment FJ ⊥ line segment FH (given)

2) ∠HGI = ∠FGJ (It is also given)

3) HI = FJ (Given). So HI ≅ FJ

4) HI ⊥ FH (given)

5) Since both the angles F and H are right angles,

∠F ≅ ∠H (since all right angles are congruent)

6) So we get that two angles and a non included side of ΔGHI are equal to the corresponding two angles and a non included side of ΔGFJ.

So by AAS congruence theorem, ΔGHI ≅ ΔGFJ.

Hence the given two triangles are congruent.

If the amount of medication in the body decrease by a factor of 1/3 each hour , then the exponential function is y = 1.8(2/3)ˣ .

Let M = the initial amount of medication administered = 1.8 milliliters , and

Let y = the amount of medication remaining in the patient's body after x hours.

We know that the medication amount will decrease by a factor of 1/3 each hour, which means that after 1 hour, only (1-1/3) = 2/3  of the medication will remain, after 2 hours, only (2/3)² will remain, and so on.

So we can write the equation in exponential form as :

⇒ y = M × (1-1/3)ˣ

⇒ y = M × (2/3)ˣ ;

substituting the initial value as 1.8  ,

we get ;

⇒ y = 1.8 × (2/3)ˣ ;

where x = number of hours that have passed since the medication was administered.

The 5th term of the arithmetic sequence is a₅ = 9/20

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the first term of the AP a₁ = 1/4

The second term of the AP is a₂ = 3/10

So , the common difference is d = 3/10 - 1/4 = 1/5

Now , the arithmetic progression will be

The 5th term of the AP a₅ = a + ( n - 1 ) d

Substitute the values in the equation , we get

The 5th term of the AP a₅ = 1/4 + ( 5 - 1 ) ( 1/5 )

On simplifying the equation , we get

The 5th term of the AP a₅ = 1/4 + 4/5

The 5th term of the AP a₅ = 9/20

Hence , the 5th term of the AP 9/20

It would take Tracy and Dave approximately 4.8 hours to complete the task together. So, the correct option is C.

To solve this problem, we can use the formula:

time = work / rate

where work is the amount of work to be done (in this case, collecting signal strength data from each house), and rate is the rate at which the work is being done.

Let's start by finding Tracy's and Dave's individual rates:

Tracy's rate: 1 job / 8 hours = 0.125 jobs per hour

Dave's rate: 1 job / 12 hours = 0.0833 jobs per hour

Now, let's find their combined rate when they work together:

Combined rate = Tracy's rate + Dave's rate

Combined rate = 0.125 + 0.0833

Combined rate = 0.2083 jobs per hour

Finally, we can use the formula time = work / rate to find how long it would take them to complete the task together:

Answer: To find the range of the marks obtained, we need to find the difference between the highest and lowest marks:

Range = highest mark - lowest mark

To find the highest and lowest marks, we can simply sort the marks in ascending or descending order:

39, 48, 56, 75, 76, 81, 85, 85, 90, 95

So, the highest mark is 95 and the lowest mark is 39. Then, the range is:

Range = 95 - 39 = 56

To find the mean marks obtained by the group, we need to add up all the marks and divide by the number of marks:

Mean = (85 + 76 + 90 + 85 + 39 + 48 + 56 + 95 + 81 + 75) / 10

   = 745 / 10

   = 74.5

So, the mean marks obtained by the group is 74.5.

If a red ball is drawn from two urns containing colored balls , then the probability that it came from the first urn is  0.625 or 62.5%   .

Let A = the event that the first urn is chosen, and

B is = the event that a red ball is drawn.

We have to find P(A|B), which means , the probability that the first urn was chosen given that a red ball was drawn.

So , By Bayes' theorem:

we have , P(A|B) = P(B|A) × P(A) / P(B)  ;

Since each urn has an equal probability of being chosen, we have P(A) = P(B) = 1/2 ; and

the probability of drawing a red ball is the same regardless of which urn was chosen.

We need to find P(B|A), the probability of drawing a red ball from the first urn is 50/100 = 0.5   ;

To find P(B), the overall probability of drawing a red ball, we can use the law of total probability:

that is ; P(B) = P(B|A) × P(A) + P(B|A') × P(A')  ;

where A' = event that the second urn was chosen.

Now , we find P(B|A'), which is the probability of drawing a red ball from the second urn is = 30/100 = 0.3    ;

We know that P(A') = 1/2 = 0.5 , because there are only 2 urns.

So , we have : P(A|B) = P(B|A)×P(A) / P(B)  ;

= (0.5×0.5) / (0.5×0.5 + 0.3×0.5)

= 5/8

= 0.625

Therefore, the probability that the red ball came from the first urn is 0.625 or 62.5%   .

Given the equation in the question

6(72(x - 2)) = 4(15 - 3x)

To solve the equation, remove the parenthesis by applying distributive property.

6( 72 × x - 72 × 2 ) = 4 × 15 - 4 × 3x

6( 72x - 144 ) = 60 - 12x

6( 72x - 144 ) = 60 - 12x

6 × 72x - 6 × 144 = 60 - 12x

432x - 864 = 60 - 12x

Collect like terms

Add -12x to both sides

432x + 12x - 864 = 60 - 12x + 12x

432x + 12x - 864 = 60

Add 864 to both sides

432x + 12x - 864 + 864 = 60 + 864

The probability that at least one is a boy, given that at least one is a girl is 0.823

To solve this problem, we can use conditional probability.

Let A be the event that at least one student is a boy, and let B be the event that at least one student is a girl.

We want to find the probability of A given B, denoted as P(A|B).

Let total student is,

Total girls (10) + Total boys (12) = 22

First calculating the probability of event B, which is probability that all three students are boys. This can be calculated as:

P(B) = 1 - (10/22)^3 = 1 - 0.214 = 0.906

The probability of event A intersecting B is then calculated, which is the probability that at least one student is a boy and at least one student is a girl. We can use the complement of this event, which is the likelihood that all three students are male or female:

P(A intersect B) = 1 - P(all girls) - P(all boys)

= 1 - (10/22)^3 - (12/22)^3

= 1 - 0.077 - 0.245

= 0.743

Finally, we use the formula for conditional probability to calculate P(A|B):

P(A|B) = P(A intersect B) / P(B)

= 0.743 / 0.906

= 0.822

Therefore, the probability that at least one student is a boy, given that at least one is a girl, is 0.862.

The probability that a randomly chosen person has diabetes is 34.2 million / (0.105 * total population).

The probability that a randomly chosen person has diabetes is equal to the number of people who have diabetes divided by the total population:

probability = number of people with diabetes / total population

Substituting the given values:

probability = 34.2 million / (10.5% of the total population)

To calculate this, we need to convert the percentage to a decimal by dividing by 100:

probability = 34.2 million / (0.105 * total population)
