On solving the provided question we can say that Therefore, the percent decrease in video games sales in consoles is approximately 10.43%.

Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent symbol (%). For example, if a student scores 80 out of 100 in a test, the percentage score is calculated as (80/100) x 100, which is equal to 80%. This means the student scored 80% of the total marks available in the test. Percentages are commonly used to express rates of change, proportions, and percentages of a whole, and they are used in many fields, such as finance, science, and statistics.

$1,150 million - $1,030 million = $120 million

$120 million ÷ $1,150 million = 0.1043

0.1043 x 100% = 10.43%

Therefore, the percent decrease in video games sales in consoles is approximately 10.43%.

the answer is that Sophia, Lexi, and Jason collected a total of 162 bananas.

In this problem, we are given that Sophia picked 18 bananas. We are also told that Lexi picked 6 more bananas than Sophia, so Lexi picked 18+6=24 bananas. Additionally, we are told that Jason picked 5 times as many bananas as Lexi, so we need to multiply Jason picked 5*24=120 bananas.

To find the total number of bananas picked by all three people, we need to add up the number of bananas picked by Sophia, Lexi, and Jason. So, we add 18 + 24 + 120 = 162 bananas.

Therefore, the answer is that Sophia, Lexi, and Jason collected a total of 162 bananas.

It's important to understand the relationships between the numbers given in the problem in order to solve it. Sophia is the starting point, with 18 bananas, and Lexi is picking 6 more bananas than her. Jason's number is more complex, being 5 times Lexi's amount. By breaking down each piece of information and understanding how they relate to each other, we can easily find the total number of bananas collected by all three.

The total cost of the water piping is $217.12 in the field.

Perimeter is the total length of the boundary or the outer edge of a two-dimensional geometric shape. It is the distance around the shape or the sum of the lengths of all its sides. The perimeter is usually measured in units such as centimeters, meters, feet, or inches, depending on the system of measurement used.

In the given question,

To calculate the total cost of the water piping, we need to first calculate the total length of the edges of the field.

For the rectangle, the length of its four edges can be calculated as:

2 x length + 2 x breadth = 2 x 68m + 2 x 64m = 136m + 128m = 264m

For the square extension, it has four edges each with length 26m, so the total length of its edges is:

4 x 26m = 104m

Therefore, the total length of the edges of the field is:

264m + 104m = 368m

To find the total cost of the water piping, we can multiply the total length of the edges by the cost per metre:

368m x $0.59/m = $217.12

So, the total cost of the water piping is $217.12.

Answer:

the GCF is 5y and the factored form is 5y(2y^4 + 6y^2 - 3).

Step-by-step explanation:

The greatest common factor (GCF) of the terms 10y^5, 30y^3, and -15y is 5y.

To factor out the GCF, we can divide each term by 5y:

10y^5 / (5y) = 2y^4

30y^3 / (5y) = 6y^2

-15y / (5y) = -3

So we have:

10y^5 + 30y^3 - 15y = 5y(2y^4 + 6y^2 - 3)

Therefore, the GCF is 5y and the factored form is 5y(2y^4 + 6y^2 - 3).

Answer: GCF=5

In order to obtain a 96.5% confidence interval of width of at most 0.16 for the probability of flipping a head in a coin flipping experiment, the coin needs to be flipped 533 times.

How to calculate the number of times we have to flip a coin?

We can use the formula:

n = ((Z_α/2) / E)²

Where, n is the number of times we need to flip a coin,

Z_α/2 is the Z-score at the α/2 level of significance for the normal distribution, and E is the desired margin of error or the maximum allowable deviation from the population proportion.

In this problem, the margin of error is 0.16, and the confidence level is 96.5%.

The α value is 1 - 0.965 = 0.035.

We need to find the Z-score corresponding to α/2 = 0.0175 using a standard normal distribution table.

Z_0.0175 = -1.96n = ((-1.96) / 0.16)²n ≈ 533

Therefore, the coin needs to be flipped 533 times to obtain a 96.5% confidence interval of width of at most 0.16 for the probability of flipping a head.

The evaluation of the function gives:

f(-4) = 1, f(1) = 2, f(2) = 6, f(5) = 29/3

A function is an expression that shows the relationship between the independent variable and the dependent variable.  A function is usually denoted by letters such as f, g, etc.

The evaluation is as follow:

For f(-4):

since x = -4. This means x ≤ -4. Thus, we use the function |2x + 7|. That is:

f(-4) = |2*(-4) + 7|

f(-4) = |-8 + 7|

f(-4) = | -1 |

f(-4) = 1

For f(1):

x = 1. Thus, -4< x ≤ 1. Use 1 + x²

f(1) = 1 + x²

f(1) = 1 + 1²

f(1) = 2

For f(2):

x = 2. Thus, 1< x < 3. Use the value 6

f(2) = 6

For f(5):

x = 5. Thus, x ≥ 3. Use (1/3)x + 8.

Evaluating the function at various values of x over different intervals,

f(-4) = 1, f(1) = 2, f(2) = 6, f(5) = 29/3

To evaluate the function f(x) at various values of x, we need to use the definition of the function for each interval of x.

For x ≤ -4:

f(x) = |2x + 7|

f(-4) = |2(-4) + 7| = |-1| = 1

For -4 < x ≤ 1:

f(x) = 1 + x²

f(1) = 1 + 1² = 2

For 1 < x < 3:

f(x) = 6

f(2) = 6

For x ≥ 3:

f(x) = (1/3)x + 8

f(5) lies in the interval x ≥ 3, so we use the definition of f(x) for this interval:

f(5) = (1/3)(5) + 8 = 29/3

The output of g(x) when x is -2 is 1/3.

How to find output?

To find the output of g(x) when x is -2, we simply substitute -2 into the formula for g(x):

g(-2) = 3⁻²/²

Simplifying the exponent, we get:

g(-2) = 3⁻¹

Now, we need to evaluate 3⁻¹. Recall that any number raised to a negative exponent can be written as its reciprocal raised to the corresponding positive exponent. That is:

a⁻ⁿ = 1/(aⁿ)

In our case, a is 3 and n is 1, so we have:

3⁻¹= 1/(3¹) = 1/3

Therefore, the output of g(x) when x is -2 is 1/3.

Note that 1/3 is already in its simplest form, so we do not need to simplify it any further. We also do not need to round it to two decimal places since it is a fraction.

We can use trigonometry to solve this problem. Let the length of the rope be x. Then, we can draw a right triangle where the height of the tree is the opposite side, the length of the rope is the hypotenuse, and the angle of elevation is 60 degrees. The adjacent side can be found using the trigonometric function cosine:

cos 60° = adjacent / hypotenuse

1/2 = adjacent / x

Multiplying both sides by x, we get:

x/2 = adjacent

To find the length of the hypotenuse, we can use the Pythagorean theorem:

hypotenuse^2 = adjacent^2 + opposite^2

Substituting in the values we know, we get:

x^2 = (x/2)^2 + (9√5)^2

Simplifying the right side, we get:

x^2 = x^2/4 + 405

Multiplying both sides by 4, we get:

4x^2 = x^2 + 1620

Subtracting x^2 from both sides, we get:

3x^2 = 1620

Dividing both sides by 3, we get:

x^2 = 540

Taking the square root of both sides, we get:

x = √540 = 6√60

Therefore, the length of the rope that Rachel needs to hang the piñata is 6√60 feet. Rounded to the nearest tenth, this is approximately 74.1 feet.

Answer:

  43.4 ft

Step-by-step explanation:

You want to know the length of rope needed to hang a piñata from the top of a tree that is 9√5 feet tall, if the rope makes an angle of 60° with the ground.

The hypotenuse of the triangle can be found by considering the sine of the 60° angle. The sine of the angle is given by ...

  Sin = Opposite/Hypotenuse

Then the hypotenuse of the triangle can be found from ...

  sin(60°) = tree height / hypotenuse

  hypotenuse = tree height/sin(60°) = 9√5/sin(60°)

We presume the length of rope Rachel wants is the total of the lengths from the anchor point to the tree top and back to the ground. That will be ...

  9√5 + 9√5/sin(60°) = 9√5·(1 +1/sin(60°)) ≈ 43.4 . . . . feet

Rachel needs about 43.4 feet of rope to hang the piñata.

The probability of getting P(sum > 9) when a cube is rolled twice is 6/36.

Mathematical study of random occurrences and their results is the subject of probability theory. It entails analysing and quantifying risk, chance, and uncertainty. For modelling and studying complex systems and events in disciplines like physics, engineering, economics, and finance, probability theory offers a framework. Concepts like random variables, probability distributions, expected values, variance, and covariance are all part of the theory. In many aspects of daily life, including forecasting weather patterns, data analysis for scientific study, and calculating the likelihood of certain outcomes in games of chance, probability theory is applied.

The total number of outcomes for a 6 sided cube rolled twice is 6 x 6 = 36.

For a sum greater than 9 the possibilities are:

(4, 6), (5, 5), (5, 6), (6, 4), (6, 5), (6, 6) = 6 possibilities.

Thus,

P(sum > 9) = 6 / 36.

For the given linear equation, the solution is (3,3) i.e. B.

What is a linear equation, exactly?

A linear equation is a mathematical equation in which the highest power of the variable(s) is one. In other words, it is an equation of the form:

y = mx + b

where y and x are variables, m is the slope or gradient of the line, and b is the y-intercept (the point at which the line intersects the y-axis). The slope represents the rate of change of the line, or how steep it is, and the y-intercept represents the value of y when x is zero.

Now,

We can solve this problem by plugging in the x and y values of each ordered pair and seeing if they make the equation true.

Let's start with option A, which is (2,4):

-3x+5y = 2x+3y (original equation)

-3(2) + 5(4) = 2(2) + 3(4) (substituting x=2 and y=4)

-6 + 20 = 4 + 12

14 = 16

The left side of the equation is not equal to the right side, so (2,4) is not a solution.

Now let's move on to option B, which is (3,3):

-3x+5y = 2x+3y (original equation)

-3(3) + 5(3) = 2(3) + 3(3) (substituting x=3 and y=3)

-9 + 15 = 6

6 = 6

The left side of the equation is equal to the right side, so (3,3) is a solution.

Therefore, the answer is option B, which is "Only (3,3)".

The tour guide should row towards the point on the coast closest to point Q, which is the point of perpendicular intersection between the coast and the line passing through points Q and the initial position of the tour guide.

To reach point Q in the least time, the tour guide should row towards the point on the coast that is closest to point Q. Let's call this point P.

We can use the Pythagorean theorem to find the distance from point P to point Q

distance PQ = sqrt((3 miles)^2 + (1 mile)^2) = sqrt(10) miles

Now, let's consider two scenarios

Scenario 1: The tour guide rows directly towards point Q.

The distance the tour guide needs to row is 2 miles + sqrt(10) miles. This will take the tour guide

time = (2 miles + sqrt(10) miles) / (3 miles/hour) = (2/3) + (1/3)*sqrt(10) hours

Scenario 2: The tour guide rows towards point P, then walks the rest of the way to point Q.

The distance the tour guide needs to row is 2 miles - x miles, where x is the distance from point P to the nearest point on the coast. By similar triangles, we know that

x / 3 miles = 1 mile / sqrt(10) miles

Solving for x, we get

x = 3/sqrt(10) miles

So the distance the tour guide needs to row is

2 miles - 3/sqrt(10) miles = 2 - (3/sqrt(10)) miles

The distance the tour guide needs to walk is

sqrt(10) miles - 1 mile = sqrt(10) - 1 miles

The time it takes the tour guide to row and walk is:

time = (2 - (3/sqrt(10))) / (3 miles/hour) + (sqrt(10) - 1) / (3 miles/hour)

Simplifying this expression, we get

time = (2/3) - (1/3)*sqrt(10) + (sqrt(10)/3) - (1/3) = (1/3) + (1/3)*sqrt(10) hours

Comparing the two scenarios, we see that scenario 2 takes less time, so the tour guide should row towards point P in order to reach point Q in the least time.

2×10⁴ seconds to reach Pluto

= 2 x 100000 = 200000 seconds

now lets convert the time it takes for the light to reach earth from the sun:

5×10² seconds to reach Earth

= 5 x 1000 = 5000 seconds

therefore the difference = time taken to reach Pluto - time taken to reach Earth
