Step-by-step explanation:

Ayo received 395 units of money.

Let's assume that Ali received x amount of money. Since Ayo received 70 more than Ali, Ayo would receive x + 70.

According to the given information, the total amount of money to be shared is 720. So we can set up the equation:

x + (x + 70) = 720

Simplifying the equation:

2x + 70 = 720

Next, let's isolate the variable x by subtracting 70 from both sides of the equation:

2x + 70 - 70 = 720 - 70

Simplifying:

2x = 650

Finally, we divide both sides of the equation by 2 to solve for x:

2x/2 = 650/2

x = 325

Therefore, Ali received 325 units of money, and Ayo received 325 + 70 = 395 units of money.

The correlation for the resulting data, when each of the X values were multiplied by 2, is r=0.10.

Explanation:

Given that, a set of n=15 pairs X and Y values has a Pearson correlation of r=0.10. And, in each of the X values were multiplied by 2, then we need to calculate the correlation for the resulting data.

When each of the X values is multiplied by 2, then the resulting correlation does not change. It is because the correlation coefficient of Pearson, r, only measures the linear relationship between two variables and not the scale of the variables.

Thus, the correlation for the resulting data, when each of the X values were multiplied by 2, is r=0.10.

Answer: Total amount earned by Laney in 4hour=$138

Total amount earned by Maka in 4hours=$134

Difference =$4

Step-by-step explanation:

Since

Maka charges can be modeled by the equation F=30h+14,

where h =number of hours that Maka tutors

F = the total amount earned. Following same model

With 14 being the charge in dollar for travel expenses.

Laney charging $10 for travel expenses plus $32 per hour of tutoring can also be represented as

F= 32h +10

Such that total amount earned by

Maka in 4hours gives

F=30h+14

F=30x4 +14

F=120+14=$134

In the same vein the total amount earned by Laney in 4hours gives

F=32h+10

F= 32x4+10

F=128+10=$138

The difference in money earned by Laney and Maka = $138-$134= $4

Morris is showing his work in simplifying,

(-6.7 + 4.3) - 1.2

Step 1: (4.3 - 6.7) - 1.2

Step 2: 4.3 - (6.7 + 1.2)

Step 3: 4.3 - 7.9

Step 4: -3.6

Which statement is true ?

A). Step 1, Morris used the commutative property.

B). Step 2, Morris used the distributive property.

C). Step 3, Morris used the associative property.

D). Step 4, Morris's answer is incorrect.

In associative property,

a + (b + c) = (a + b) + c

By this property,

(-6.7 + 4.3) - 1.2

Step 1, (-6.7 + 4.3) - 1.2 = (4.3 - 6.7) - 1.2

Step 2, (4.3 - 6.7) - 1.2 = 4.3 - (6.7 + 1.2) [Use of associative property]

Step 3, 4.3 - 7.9

Step 4, -3.6

The simplified form of 37 / (√12 + √√(3√3)1) is\((74 - 37\sqrt{(3^(1/4))) } / (2\sqrt{3} - 3^(1/4)\sqrt{3} ).\)

To simplify the given expressions without using a calculator, let's break down each expression step by step:

Simplifying 2√8 - 4√32 + 3√50:

First, let's simplify the square roots individually:

√8 = √(4 × 2) = √4 × √2 = 2√2

√32 = √(16 × 2) = √16 × √2 = 4√2

√50 = √(25 × 2) = √25 × √2 = 5√2

Now, substitute these values back into the original expression:

2√8 - 4√32 + 3√50 = 2(2√2) - 4(4√2) + 3(5√2)

= 4√2 - 16√2 + 15√2

= (4 - 16 + 15)√2

= 3√2

Therefore, the simplified form of 2√8 - 4√32 + 3√50 is 3√2.

Simplifying 37 / (√12 + √√(3√3)1):

Let's start by simplifying the radicals:

√12 = √(4 × 3) = √4 × √3 = 2√3

√√(3√3)1 = √(3√3)

\(= (\sqrt{3} )^{(1/2) }\times \sqrt{3}\)

\(= 3^(1/4) \times \sqrt{3}\)

Now, substitute these values back into the original expression:

37 / (√12 + √√(3√3)1) \(= 37 / (2\sqrt{3} + 3^{(1/4)} \times \sqrt{3} )\)

To simplify further, we can factor out √3:

37 / (√12 + √√(3√3)1) \(= 37 / (\sqrt{3} (2 + 3^{(1/4)}))\)

Now, rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator:

\(37 \times(\sqrt{3} (2 - 3^{(1/4)})) / (\sqrt{3} (2 + 3^{(1/4)})) \times (\sqrt{3} (2 - 3^{(1/4)})) / (\sqrt{3} (2 - 3^(1/4)))\)

Simplifying further, we get:

\(37(2 - 3^{(1/4)}) / (2\sqrt{3} - 3^{(1/4)}\sqrt{3} )\)

\(= (74 - 37\sqrt{(3^{(1/4)})) / (2\sqrt{3} - 3^{(1/4)}\sqrt{3} )}\)

The indefinite integral of (7 - eu)^2 du is 49u - 14(e^u)/1 + e^2u/2 + C.

The indefinite integral of (7 - eu)^2 du is:

∫(7 - eu)^2 du = ∫(49 - 14eu + e^2u) du = 49u - 14(e^u)/1 + e^2u/2 + C

To evaluate the indefinite integral of (7 - eu)^2 du, we use the formula for integrating powers of exponential functions, which states that ∫e^au du = (1/a)e^au + C, where C is the constant of integration. By applying this formula, we can expand the given expression and integrate term by term.

First, we expand (7 - eu)^2 using the binomial theorem, which gives us 49 - 14eu + e^2u. Then, we integrate each term using the formula above, which gives us 49u - 14(e^u)/1 + e^2u/2 + C, where C is the constant of integration.

Therefore, the indefinite integral of (7 - eu)^2 du is 49u - 14(e^u)/1 + e^2u/2 + C.

Answer:

Both Wolverine and James Bond will have paid the same amount after 10 months.

Step-by-step explanation:

Let x denotes the number of months after which both Wolverine and James Bond will have paid the same amount.

As Wolverine makes a $1000 down payment for a motorcycle and then pays $300 per month,

Amount paid by Wolverine in x months is equal to \(1000+300x\)

As James Bond makes a $2500 down payment for a motorcycle and then pays $150 per month,

Amount paid by James Bond in x months is equal to \(2500+150x\)

To find number of months after which both Wolverine and James Bond will have paid the same amount,

solve \(1000+300x=2500+150x\)

\(1000+300x=2500+150x\\300x-150x=2500-1000\\150x=1500\\x=\frac{1500}{150}=10\)

So, both Wolverine and James Bond will have paid the same amount after 10 months.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The length of the wire is 81.5 meters.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The length of the tower is 80 meters, while the angle of elevation is 79°. Therefore, the length of the wire will be the hypotenuse of the triangle. Therefore, the length of the wire is,

Sin(θ) = Perpendicular/Hypotenuse

Sin(79°) = 80 meter/Length of the wire

Length of the wire = 81.4973 ≈ 81.5 meters

Hence, the length of the wire is 81.5 meters.

The equation to determine the length and width of the rug is

28 = w² + 12w

Since, the shape of the rug is rectangle, therefore area of rectangle has been used to obtain the solution.

What is a rectangle?

Rectangle is a flat, two-dimensional shape, having four sides and vertices with opposite sides being equal and parallel. We may easily represent a rectangle in an XY plane by using its length and breadth as the arms of the x and y axes, respectively.

Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel.

We are given a rectangular rug with an area of 28 square feet.

Also, the rug is 12 feet longer than it is wide.

So,

Let 'l' be the length of the rug and 'w' be the width of the rug

As given, Length is 12 feet longer than its width

Therefore, l = w + 12

We know Area of rectangle = Length * Width and area is given to be 28 square feet.

So,

⇒28 = (w + 12)w

⇒28 = w² + 12w

Hence, the equation to determine the length and width of the rug is

28 = w² + 12w.
