Answer:

DG = 12 , GC = 24

Step-by-step explanation:

DC is a median of Δ ABC

on each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is

GC = 2 DG , then

DG + GC = DC , that is

DG + 2 DG = 36

3 DG = 36 ( divide both sides by 3 )

DG = 12

thus

DG = 12 and GC = 2 × 12 = 24

Therefore, the likelihood of a thunderstorm is roughly 0.2174, or a 21.74% chance that one will occur.

The study of random events or phenomena falls under the category of probability, which is a branch of mathematics. It is a way to quantify the possibility or likelihood of an event happening. A number between 0 and 1, where 0 denotes an improbable occurrence and 1 denotes a certain event, is used to express probability. By dividing the number of favorable outcomes by the total number of possible outcomes, one can determine the probability of an occurrence. In many disciplines, including statistics, economics, engineering, and science, probability is used to make predictions and well-informed choices in uncertain situations.

given

We must divide the amount of beneficial outcomes (chances of a thunderstorm) by the total number of possible outcomes in order to express the suggested degree of likelihood as a probability value between 0 and 1 inclusive.

When the likelihood of a thunderstorm is stated as "5 in 23," it indicates that out of a possible 23, 5 outcomes are likely to be favorable.

Therefore, the likelihood of a rainstorm is:

P (thunderstorm) is the ratio of the number of successful outcomes to all other possible outcomes.

Thunderstorm P(thunder) = 5 / 23

As a result, the probability value for the indicated degree of likelihood can be expressed as:

P(thunderstorm)= 5/230.2174

Therefore, the likelihood of a thunderstorm is roughly 0.2174, or a 21.74% chance that one will occur.

Answer:

Lamar claims that the weight of her cat is "almost 11 pounds".

Since Lamar is using the word "almost", we can assume that she means the weight of her cat is very close to 11 pounds, but not exactly 11 pounds.

Therefore, we can represent Lamar's claim with the inequality:

B) w < 11

This is because if the weight of Lamar's cat is almost 11 pounds, but not exactly 11 pounds, then the weight must be less than 11 pounds.

To solve this division problem, we can use the rule "division is the same as multiplication by the reciprocal".

What is interest ?

Interest is the cost of borrowing money, usually expressed as a percentage of the amount borrowed. It is also the amount earned on an investment, usually expressed as a percentage of the amount invested. The rate of interest is determined by factors such as the level of risk involved, the term of the loan or investment, and prevailing market conditions.

To calculate the monthly deposit required, we can use the formula for the future value of an annuity:

FV = P * (((1 + r/n)[tex]^{(n*t)}[/tex]- 1) / (r/n))

where FV is the future value, P is the monthly deposit, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, we want to solve for P, so we can rearrange the formula:

P = FV * (r/n) / (((1 + r/n)[tex]^{(n*t)}[/tex]- 1))

Substituting the given values, we get:

P = 600000 * 0.04/12 / (((1 + 0.04/12)[tex]^{(12*25)}[/tex]- 1))

Simplifying and solving for P, we get:

P ≈ $1,518.14 per month

To calculate the interest earned, we can use the formula:

I = FV - P * t

where I is the interest earned, FV is the future value, P is the monthly deposit, and t is the number of years.

Substituting the given values, we get:

I = 600000 - 1518.14 * 12 * 25

Simplifying, we get:

The answer of the question based on monthly installment is Anver's monthly installment is R6 253.27.

What is Formula?

In mathematics,  formula is  set of symbols or expressions representing mathematical relationship or the rule. Formulas are often used to describe and solve the problems in mathematics, science, engineering, and other fields.

To determine the amount of the loan, we can calculate 85% of the price of the van, which is the amount that Anver would have to borrow after paying the 15% deposit:

Amount of loan = 85% of R392 900

= 0.85 x R392 900

= R333 965

To determine the monthly installment, we need to use the formula for the present value of an annuity:

PV = PMT x (1 - (1 + r/n)^(-nt)) / (r/n)

We can calculate the annual interest rate by adding 1% to the prime rate. According to the South African Reserve Bank, the prime rate in September 2013 was 9%.

Annual interest rate = prime rate + 1%

= 9% + 1%

= 10%

Therefore, we can substitute the given values into the formula:

PV = R333 965

r = 10% / 12 = 0.8333%

n = 12

t = 72 / 12 = 6

Rearranging the formula to solve for PMT, we get:

PMT = PV x (r/n) / (1 - (1 + r/n)^(-nt))

Substituting the values, we get:

PMT = R6 253.27 (rounded to two decimal places)

Therefore, Anver's monthly installment is R6 253.27.

Answer:

Raju spent a total of Rs 919.50. He bought 4 books at Rs 222.75 each, which cost Rs 891, and 2 books at Rs 14 each, costing Rs 28.50

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's first calculate the total cost of the 4 books that Raju bought:

Cost of 1 book = Rs 222.75

Cost of 4 books = 4 x Rs 222.75 = Rs 891

Now, let's calculate the amount of money Raju received by selling 2 books at Rs 14 each:

Amount received by selling 1 book = Rs 14

Amount received by selling 2 books = 2 x Rs 14 = Rs 28

Therefore, the total cost of 4 books is Rs 891 and the total amount received by selling 2 books is Rs 28. To find Raju's overall expenditure, we need to subtract the amount received from the total cost of 4 books:

Raju's overall expenditure = Total cost of 4 books - Amount received by selling 2 books

= Rs 891 - Rs 28

= Rs 863

Therefore, Raju's overall expenditure is Rs 863.

The area of the image of the triangle under T is 5/9.

What is Triangle?

In geometry, a triangle is a closed two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and is characterized by its three vertices (points where two sides intersect) and three sides (line segments that connect the vertices). The sum of the interior angles of a triangle is always 180 degrees, and the length of each side is less than the sum of the lengths of the other two sides.

To show that T maps the given triangle to the domain D, we need to find the image of the three vertices of the triangle under T and then show that the image lies inside D.

Let's first consider the vertex (0,0) of the triangle. Applying T, we get T(0,0) = (0,0). So the image of the vertex (0,0) is the origin, which clearly lies inside D.

Now let's consider the vertex (1,1) of the triangle. Applying T, we get T(1,1) = (0,2), which lies on the y-axis and satisfies y²=4-4x, so it lies inside D.

Finally, let's consider the vertex (u,0) of the triangle, where 0≤u≤1. Applying T, we get T(u,0) = (u²,0). This lies on the x-axis and satisfies y²=4-4x only when x=1, which is outside D. Therefore, the image of this vertex is not inside D.

Hence, we can conclude that T maps the triangle to the domain D, except for the line segment {(u,0):0≤u≤1}.

To evaluate the area of the image, we can use the fact that the area of the image of a region under a transformation is equal to the absolute value of the determinant of the Jacobian matrix of the transformation, multiplied by the area of the original region.

The Jacobian matrix of T is given by

J(T) = [2u -2v]

[2v 2u]

The absolute value of the determinant of this matrix is 4u² + 4v², so the area of the image of the triangle is

∫∫R 4u²+4v² dA,

where R is the region in the uv-plane corresponding to the triangle.

Integrating over R, we get

∫0 ∫v 4u²+4v² dudv

= ∫0 (4/3) (1-v³+3v²) dv

= (4/3) (1/4 - 1/16 + 1/3 - 1/12)

= 5/9.

Therefore, the area of the image of the triangle under T is 5/9.
