m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

(0,300) and (5,0)

m = y2 - y1/x2 - x1

m = 0 - 300/5 - 0

m = -300/5

m = -60/1

m = -60

y-intercept = b = 300

slope intercept form: y = mx + b

y = mx + b

y = -60x + 300

Answer:

m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

The Difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

To find the difference in the amounts that Tsion and Ibrahim paid for their watches, we need to convert the prices to the same currency. We can use the exchange rates given to convert both prices to pounds.

1 Singapore dollar = £0.58

72 Singapore dollars = 72 x £0.58 = £41.76

1 Hong Kong dollar = £0.09

399 Hong Kong dollars = 399 x £0.095 = £37.91

Therefore, Tsion paid £41.76 for the watch and Ibrahim paid £37.91 for the same model of watch.

To find the difference in the amounts paid, we can subtract the smaller amount from the larger amount:

£41.76 - £37.91 = £3.85

Therefore, the difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

Volume is the space occupied by an object. The volume of the globe is 268.0825 in³.

The volume of the sphere is given by the formula,

\(\text{Volume of Sphere}= \dfrac{4}{3} \pi r^3\)

We know that the diameter of the globe is reduced to half, therefore, the diameter of the globe,

\(\rm \text{New Diameter of the globe} = \dfrac{Diameter}{2} = \dfrac{16}{2} = 8\ inches\)

Also, the radius of the globe is half of its diameter,

\(\rm Radius = \dfrac{Diameter}{2} = \dfrac{8}{2} = 4\ inches\)

We know that the shape of a globe is spherical, also, we know the formula of the volume of the sphere, therefore, the volume of the globe can be written as,

\(\begin{aligned}\text{Volume of Globe}&= \dfrac{4}{3} \pi r^3\\\\& =\dfrac{4}{3} \pi (4)^3\\\\&=268.0825\rm\ in^3 \end{aligned}\)

Hence, the volume of the globe is 268.0825 in³.

The data represented by table number one is showing the linear relation.

A linear relationship (or linear association) is a statistical term that describes a two-variable relationship that follows a straight line.

The momentum of a variable is represented by the rate of change, which is used to mathematically describe the percentage change in value over a defined period of time. If the rate of change is constant then the relationship will be linear.

For table number one the data is,

x    F(x)

1     12

2    19

3    26

4    33

The rate of change will be,

R₁ = ( 19 - 12 ) / ( 2 - 1 )  = 7

R₂ = ( 26 - 19 ) / ( 3 - 1 ) = 7

R₃ = ( 33 - 26 ) / ( 4 - 3 )= 7

The average daily float for the BBC Corporation, based on receiving 30 checks totaling $250,000 with an average delay of five days, is $41,667.

To calculate the average daily float, we need to determine the total amount of funds in transit and divide it by the average number of days the funds are delayed.

In this case, the BBC Corporation receives 30 checks totaling $250,000 in a typical month. The average delay for these checks is five days.

To calculate the total amount of funds in transit, we multiply the average daily amount by the average delay:

Total funds in transit = Average daily amount × Average delay

= ($250,000 / 30 days) × 5 days

= $8,333.33 × 5

= $41,666.67

Rounding to the nearest whole number, the average daily float is $41,667.

t(g)= -4g + 20

Step-by-step explanation:

James is playing his favorite game at the arcade. After playing the game 3 times, he has 8 tokens remaining. He initially had 20 tokens, and the game costs the same number of tokens each time. The number tt of tokens James has is a function of gg, the number of games he plays

Solution

Let

g=No. of games James plays

t= No. of tokens James has.

Find the slope using

y=mx + b

Where,

m = Slope of line,

b = y-intercept.

Before James started playing the games, he has a total of 20 tokens.

That is, when g=0, t=20

After James played the games 3 times, he has 8 tokens left

That is, when g=3, t=8

(x,y)

(0,20) (3,8)

m=y2-y1 / x2-x1

=(8-20) / (3-0)

The tendency to perceive meaningful patterns in random sequences of outcomes often leads us to underestimate the extent to which outcomes result from CHANCE .

The word "chance" describes unpredictability or the unexpected in relation to things like events that happen without a clear reason why and without human intention.

The conclusion is that chance is the tendency of people to recognize different kinds of significant patterns in a random order or sequence in addition to evaluating any kind of outcome. Because chance can also result in an underestimating of a system's conclusion or result, it is crucial to consider it when conducting an investigation.

Answer:

If AR = 26, find AD = 13

If BD = 9, find BQ = 18

If MQ = 35, find LQ = 17.5

If LP = 13.25, find NP = 26.50

Step-by-step explanation:

For the first question which is finding AD, is basically half the line of AR. So it's half of AR.

26 ÷ 2 = 13

For the second question which is finding BQ, the line is just 2x the line of BD. So it's 2 times of BD.

9 x 2 = 18

For the third question which is finding LQ, it's half the line of MQ. So it's half of MQ.

35 ÷ 2 = 17.5

For the fourth question which is finding NP, it's 2 times of LP. So it's 2 times of LP.

13.25 x 2 = 26.50

Given Kite ABCD, in which AN=3.6m, the length of AC is 7.2 m.

Length is a measurement of how long or short something is. It can be measured in inches, feet, meters, or other standard units. Length is used to measure the size of objects, the distance between two points, and many other things. Length is an important concept in mathematics and science, and is used to compare and contrast objects, measure angles and distances, and solve problems.

The length of AC can be found using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the sum of the squares of two sides of the triangle is equal to the square of the third side.

In this case, the triangle ABCD is a right triangle, since one of the angles is 90 degrees. The side AB is equal to AN, or 3.6 m. The side AC is the hypotenuse, so we need to find the length of that side.

In the given figure

ABCD is a kite

AC is the shortest diagonal

BD is the longest diagonal

By using the fact above

BD ⊥ AC

BD bisects AC

AC ∩ BD at the point N

→ That means N is the midpoint of AC

N is the midpoint of AC

AN = NC

AN = 3.6 m

NC = 3.6 m

AC = AN + NC

AC = 3.6 + 3.6

AC = 7.2 m

Therefore, the length of AC is 7.2 m.

Answer:

x = 4

Step-by-step explanation:

You know that B = 100

E = 43 (Vertical angles are congruent)

Since vertical angles are congruent E = 43

Now that you have solved for 2 angles in the triangle you can set up an equation.

The interior angles of a triangle must add up to 180.

100+43+(10x-3)=180

(Simplify)

143+(10x-3)=180

(Subtract 143 from both sides)

10x-3=37

(Add 3 to both sides)

10x=40

The conclusion, the availability of resources such as water, food, and shelter affects the populations of organisms in an ecosystem.

In an ecosystem, the availability of resources such as water, food, and shelter have an impact on the populations of organisms living in that ecosystem. Populations are affected by the availability of resources, including abiotic and biotic factors that help support their survival.

The interaction between different populations of organisms in the ecosystem is essential, which includes plants and animals living together. In the ecosystem, the food chain is the primary interaction where organisms eat other organisms to survive.

Organisms such as herbivores feed on plants and serve as food for carnivores. The availability of food is a significant factor that determines the population of herbivores and carnivores in an ecosystem. The ecosystem also depends on the availability of water, which is vital for the survival of all organisms. Lack of water can lead to a decrease in population, especially for organisms that are unable to survive in dry environments.
Additionally, the availability of shelter is also significant in determining the population of an organism in an ecosystem. The shelter can include caves, trees, and other structures that serve as protection for organisms. The availability of shelter can influence the number of organisms that can survive in the ecosystem.

Understanding how resources availability impacts populations of the organisms in an ecosystem is crucial in preserving the ecosystem. Ecosystems with a balanced population of organisms are considered healthy, while those with unbalanced populations of organisms are considered unhealthy.
