I cant truly graph it but the coordinates would be (0,-2) (3,-4) (6,-6) (9,-8)

To solve the system of equations:

4x^2 + 9y^2 = 72

x^2 - y^2 = 5

We can use the method of substitution. Let's solve the second equation for x^2:

x^2 = y^2 + 5

Now substitute x^2 in the first equation:

4(y^2 + 5) + 9y^2 = 72

4y^2 + 20 + 9y^2 = 72

13y^2 + 20 = 72

13y^2 = 52

y^2 = 4

y = ±2

Substituting y = 2 into x^2 = y^2 + 5, we get:

x^2 = 2^2 + 5

x^2 = 9

x = ±3

Therefore, the solutions to the system of equations are:

(x, y) = (-3, 2), (-3, -2), (3, 2), (3, -2)

Listing the solutions with the smallest x-values and then the smallest y-value first, we have:

(-3, -2), (-3, 2), (3, -2), (3, 2)

Answer: the bus is going 27mph

Step-by-step explanation: 40km is 27 miles

The average speed of the bus will be 80 km per hour.

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

If a bus travels 40 km in 30 minutes. Then the average speed of the bus is given as,

Average speed = 40 / 30

Average speed = 1.33 km per minute

Average speed = 1.33 x 60

Average speed = 80 km per hour

The average speed of the bus will be 80 km per hour.

The thickness of the clay layer, which drains only from the upper surface, can be determined based on the consolidation settlement observations. With 50% of consolidation settlement occurring in 1 hour for a 25 mm thick specimen, and a total primary consolidation settlement of 35 mm occurring over many years, the thickness of the clay layer is approximately 87.5 mm.

The consolidation settlement of a clay specimen can be used to estimate the thickness of a clay layer that drains only from the upper surface. In this case, the observed settlement data provides valuable information.

Firstly, we know that 50% of the consolidation settlement occurs in 1 hour for a 25 mm thick clay specimen. This is an important parameter for calculating the coefficient of consolidation (Cv) using Terzaghi's theory. From the Cv value, we can estimate the time required for full consolidation settlement.

Secondly, we are given that the same clay settles 10 mm over 10 years and eventually settles a total of 35 mm over a longer period. This long-term settlement is known as the total primary consolidation settlement. By comparing this settlement value with the settlement data from the oedometer test, we can determine the thickness of the clay layer.

To calculate the thickness, we can use the concept of the consolidation settlement ratio. The ratio of the total primary consolidation settlement to the consolidation settlement at 50% completion is equal to the ratio of the total thickness to the thickness at 50% completion. Applying this ratio, we can determine that the thickness of the clay layer, which drains only from the upper surface, is approximately 87.5 mm.

Given:

The pie chart shows the flavours of ice cream sold by a shop in one  day.

There were a total of 270 ice creams sold.

To find:

The number of vanilla flavoured ice creams sold.

Solution:

We know that the complete central angle is 360 degrees.

From the given pie chart, it is clear that the central angle of the vanilla flavoured ice creams sold is 60 degrees.

Total ice creams sold = 270

Now, the number of vanilla flavoured ice creams sold is

\(n=\dfrac{\text{Central angle of vanilla}}{\text{Complete central angle}}\times \text{Total ice creams sold}\)

\(n=\dfrac{60^\circ}}{360^\circ}}\times 270\)

\(n=\dfrac{1}{6}\times 270\)

\(n=45\)

Therefore, the number of vanilla flavoured ice creams sold is 45.

Answer:

45

Step-by-step explanation:

a pie chart is 360 deg so if you divide 360 by 60 you get 6. That means that vanilla is 1/6 of the total icecream amount which is 270. If you multiply 270 by 1/6 (270 x (1/6)) that give you 45.

The probability at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.

To determine the probability that at least 7 of the puppies will be male, we will have to use the binomial probability formula.

P(X ≥ k) = 1 - P(X < k)

where X is the number of male puppies, P is the probability of a puppy being male and k is the minimum number of male puppies required.

We can solve this problem by finding the probability that 0, 1, 2, 3, 4, 5, or 6 of the puppies are male, and then subtracting that probability from 1. We use the binomial distribution formula to find each of these individual probabilities.

P(X=k) = nCk * pk * (1-p)n-k

where n is the total number of puppies, p is the probability of a puppy being male (0.5), k is the number of male puppies, and nCk is the number of ways to choose k puppies out of n puppies. We'll use a calculator to compute each probability:

P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)

P(X = 0) = 11C0 * 0.5⁰ * (1-0.5)¹¹ = 0.00048828125

P(X = 1) = 11C1 * 0.5¹ * (1-0.5)¹⁰ = 0.00537109375

P(X = 2) = 11C2 * 0.5² * (1-0.5)⁹ = 0.03295898438

P(X = 3) = 11C3 * 0.5³ * (1-0.5)⁸ = 0.1171875

P(X = 4) = 11C4 * 0.5⁴ * (1-0.5)⁷ = 0.24609375

P(X = 5) = 11C5 * 0.5⁵ * (1-0.5)⁶ = 0.35595703125

P(X = 6) = 11C6 * 0.5⁶ * (1-0.5)⁵ = 0.32421875

P(X < 7) = 0.00048828125 + 0.00537109375 + 0.03295898438 + 0.1171875 + 0.24609375 + 0.35595703125 + 0.32421875 = 1 - P(X < 7) = 1 - 1.08184814453 = -0.08184814453 ≈ 0.0805

Answer:

First we Check if its an AP or GP

Its an AP because the Second term Minus the First term is = to 3rd term Minus Second term

Since it said "Sum"

The formula we should think Of is

Sn = n/2[2a + (n-1)d]

n=100

a(First term) =100

Common difference 'd' = Second term - First term or Third term - Second term

So

d= 98-100 or 96-98

d=-2.

Applying the Formula...

Sn = 100/2 [2(100) + (100-1)(2)]

Sn = 50[200 + (99)(2)]

Sn= 50[200 + 198]

Sn = 50[398]

Sn = 19,900.

The right response is that the two linear equation never intersect , because the graph of these two linear equation will be two parallel lines.

How many types of solution are there for two linear equations ?

There are 2 types of solution :
Consistent :

A consistent system is said to be an independent system if it has a single solution.

A consistent system is said to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide, so the equations represent the same line. Each point on the line represents a pair of coordinates that fits the system. So there are an infinite number of solutions.

Non-consistent :

Another type of system of linear equations is the inconsistent system, in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no common points for both lines; therefore, there is no solution to the system and if we draw the graph of these equations then the graphs of both equation becomes parallel to each other.

The two linear equations never intersect.

When a system of two linear equations in two variables has no solution, it means that there is no set of values for the variables that satisfies both equations simultaneously. Geometrically, this corresponds to the two lines represented by the equations being parallel. Since parallel lines never intersect, the statement "The two linear equations never intersect" accurately describes the situation.

If the two linear equations were graphed on a coordinate plane, they would appear as two distinct lines that run parallel to each other without ever crossing or intersecting. This indicates that there is no common point of intersection between the lines, and therefore no solution exists for the system of equations.

It is important to note that this scenario is different from the case where the two linear equations represent the same line. In that case, the equations would be equivalent, and every point on the line would satisfy both equations. However, when there is no solution, it means that the lines do not share any common points and never intersect.

The coordinates of the point P is (-1,2) .

What is translation?

In mathematics, a translation is a geometric transformation that moves every point of a figure or a space by the same amount in a given direction. The amount and direction of the movement can be described using a vector, which is a mathematical object that has both magnitude and direction.

Finding the coordinates of the point P :

The coordinates of point P can be found by subtracting the vector from point Q.

To find the coordinates of point P, we need to subtract the vector \(\begin{pmatrix}4\\-3\end{pmatrix}\) from the coordinates of point Q, which are (3, -1).

Subtracting the x-coordinate of the vector from the x-coordinate of point Q gives us:

3 - 4 = -1

Similarly, subtracting the y-coordinate of the vector from the y-coordinate of point Q gives us:

-1 - (-3) = 2

Therefore, the coordinates of point P are (-1, 2).

So, the correct answer is (C) (-1, 2).

Step-by-step explanation:

The height of the cone is approximately 4 cm (rounded to the nearest whole number) and the slant height is approximately 5 cm (rounded to the nearest whole number).

To find the height (h) and slant height (l) of the right cone with a given surface area (75.4 square centimeters) and radius (3 centimeters), we can use the formula for the surface area of a cone:

Surface area = πr(l + r)

Given:
Surface area = 75.4 sq cm
Radius (r) = 3 cm

Substitute the values into the formula:
75.4 = 3π(l + 3)

First, we need to solve for l. Divide both sides by 3π:
25.4/π = l + 3

Now, subtract 3 from both sides:
25.4/π - 3 = l
l ≈ 5.08 cm (rounded to the nearest hundredth)

Next, use the Pythagorean theorem to find the height (h):
h² + r² = l²
h² + 3² = 5.08²
h² = 5.08² - 3²
h² ≈ 13.89

Thus, the probability of Jenny's favorite soccer team winning the match is 30%.

The odds against Jenny's favorite soccer team winning are 7/10. This means that for every 10 times the team plays, they are expected to win 3 times and lose 7 times.

To find the probability of her team winning, we need to use the formula:

Probability of Winning = Number of Ways to Win / Total Number of Outcomes

In this case, the number of ways to win is 3 and the total number of outcomes is 10. So, the probability of her team winning is:
Probability of Winning = 3 / 10
This can also be expressed as a percentage by multiplying the fraction by 100:
Probability of Winning = 3 / 10 x 100% = 30%

Therefore, the probability of Jenny's favorite soccer team winning the match is 30%. While this may seem like a low probability, it is important to remember that odds and probabilities are not the same thing.
