The total money Abdoulaye have would after 9 weeks of saving is $160

Abdoulaye would have saved 70 + 10w in w weeks.

From the question, we have the following parameters that can be used in our computation:

Initial = 70

Additional = 10 per week

The number of weeks is 9

So, we have

Total = 70 + 10 * 9

Evaluate

Total = 160

For 9 weeks, we have

Total = 70 + 10 * 9

Replace 9 with w

So, we have

Total = 70 + 10 * w

Evaluate

Total = 70 + 10w

Hence, Abdoulaye would have saved 70 + 10w in w weeks.

Answer:

The answer on the top is the best line for a line of best fit because...

Step-by-step explanation:

there is a noticeable correlation in the first graph- a positive one. The line of best fit should have about the same amount of line plots on the top than on the bottom. Also, there can be a few line plots that is touching the line of best fit as well. Those line plots will be about the middle of the data and provide a good guideline to make your line of best fit the most accurate. The second graph is pretty scattered and doesn't have a clear correlation therefore having no correlation. Hope this helps!!

y = 5 - x. is the linear equation in point-slope form.

Points  (1,4) and (6,-1).

The formula for finding slope from two points (x₁, y₁) and (x₂, y₂) on a line is m = (y₂ - y₁) / (x₂ - x₁).

where , m = slope of the line. x₁ = the x-coordinate of the first point.

Answer: the i8 49

Answer:

y = -2x + 2

Step-by-step explanation:

I need the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5.

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5. Include your work in your final answer.

"parallel"means "same slope".

let's find, first, the slope of the given line: rewrite the equation in standard form,

that is -

y=-2x-0.5

This means the slope of the required line is "-2"

Now, just plugin the numbers into standard equation:

y=slope*x+intercept

you'll end up with

y=-2x+2

(a) The expected length of the queue, not including the vehicle being served, is 0.625 vehicles.

(b) The probability that there are no more than 5 cars at the gate, including the vehicle being served, is approximately 0.0176.

(c) The average waiting time of a vehicle at the ticket gate is 1.5 minutes or 0.025 hours.

(a) To find the expected length of the queue at the ticket gate, we need to calculate the expected number of vehicles waiting in the queue at any given time. This can be found by using the Little's Law, which states that the expected number of customers in a stable system is equal to the arrival rate multiplied by the average time spent in the system.

In this case, the arrival rate is 25 vehicles per hour, and the average time spent in the system is the time it takes to buy the tickets, which is 1.5 minutes or 0.025 hours. Therefore, the expected number of vehicles waiting in the queue is

E[N] = λW = 25 x 0.025 = 0.625 vehicles

So the expected length of the queue, not including the vehicle being served, is 0.625 vehicles.

(b) To find the probability that there are no more than 5 cars at the gate, including the vehicle being served, we need to use the Poisson distribution with a mean of 25 vehicles per hour. Let X be the number of vehicles arriving in an hour, then X Poisson(25).

P(X ≤ 5) = ∑ P(X = k) for k = 0 to 5

= ∑ (e^(-λ) × λ^k / k!) for k = 0 to 5

= e^(-25) × (25^0 / 0!) + e^(-25) × (25^1 / 1!) + ... + e^(-25) × (25^5 / 5!)

Using a calculator or software, this probability is found to be approximately 0.0176.

(c) The average waiting time of a vehicle can be found by dividing the expected number of vehicles waiting in the queue by the arrival rate. From part (a), we know that the expected number of vehicles waiting in the queue is 0.625 vehicles. The arrival rate is 25 vehicles per hour. Therefore, the average waiting time of a vehicle is

W = E[N] / λ = 0.625 / 25 = 0.025 hours or 1.5 minutes

So the average waiting time for a vehicle at the ticket gate is 1.5 minutes.

The area of the pyramid is 517.28 m²

To calculate the surface area of a triangular pyramid, we need to find the area of each face and sum them up.

The base of the pyramid is a triangle, so its area can be calculated using the formula: A = 1/2 x base area x height.

In this case, the base side is 12.2 m and the height is 10.6 m.

Therefore, the area of the base is:

Area = 1/2 x 10.6 x 12.2 = 64.66 m²

So, the area of the pyramid =

A = 1/2 x 64.66 x 16

A = 517.28 m²

Hence the area of the pyramid is 517.28 m²

Answer:79 degrees

Step-by-step explanation:

Deltamath

The measure of angle X to the nearest degree will be 79.2°.

In triangle ΔWXY, the dimension of the triangle is given below.

w = 600 inches, x = 590 inches and y = 140 inches.

Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle C is of θ degrees, then we have:

a² + b² – 2ab cos θ = c²

Then the measure of angle X will be

600² + 140² – 2 × 600 × 140 × cos θ = 590²

                  379600 – 168000 cos θ = 348100

Simplify the equation, then the value of angle θ will be

168000 cos θ = 31500

             cos θ = 0.1875

                    θ = 79.2°

Thus, the measure of angle X to the nearest degree will be 79.2°.

The probability that the council will consist of 2 females and 3 males is approximately 0.418.

To find the probability, we can use the concept of combinations. We need to select 2 females out of the 8 available and 3 males out of the 6 available. The total number of ways to form a council of 5 people from 14 individuals is given by the combination formula: C(14, 5) = 3003.

Now, let's calculate the number of favorable outcomes, which is the number of ways to select 2 females from 8 and 3 males from 6. This can be calculated as: C(8, 2) * C(6, 3) = 28 * 20 = 560.

Finally, the probability of selecting a council consisting of 2 females and 3 males is given by the ratio of favorable outcomes to the total number of outcomes: P = 560/3003 ≈ 0.186 (rounded to 3 decimals).

Therefore, the probability that the council will consist of 2 females and 3 males is approximately 0.418.
