To solve the problem we must know about the correlation coefficients.

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".

Given to us

As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.

Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".

Answer:

The hypotenuse would be 87.2

Step-by-step explanation:

We start by plugging in 13 for x for both sides of the triangle.

[tex]5(13)+5 = 70[/tex] and [tex]4(13) = 52[/tex].

Next, we use the Pythagorean theorem

[tex]a^2+b^2=c^2[/tex]

We plug in 70 for a and 52 for b

After plugging them in, you get [tex]4900+2704=c^2[/tex]

Now, we add a and b

[tex]7604=c^2[/tex]

Finally, take the sqrt of 7604

c = 87.2009174264, rounded to the nearest tenth is 87.2

Answer:

Hypotenuse = 87.2

Step-by-step explanation:

First find the lengths of the legs given the value of x

Left leg : 5x + 5

x = 13

5(13)+5

65 + 5 = 70

Bottom Leg : 4x

x = 13

4(13) = 52

So we have legs with lengths of 70 and 52 and knowing this we want to find the length of the hypotenuse.

We can do this by using the Pythagorean Theorem : a² + b² = c²

Where a and b = legs and c = hypotenuse

We are given the legs and we want to find the hypotenuse (c)

We can do this by plugging in the values of the legs into the Pythagorean Theorem and solving for c

Pythagorean Theorem : a² + b² = c²

a = 52 and b = 70

52² + 70² = c²

52² = 2704 and 70² = 4900

2704 + 4900 = c²

7604 = c²

take the square root of both sides

√7604 = 87.2 ( rounded to the nearest tenth ) and √c² = c

We're left with c = 87.2

The length of the hypotenuse is 87.2

Answer:

Step-by-step explanation:

[tex]12^{2x-1}=(\sqrt[4]{12})^{x}\\\\ 12^{2x-1}= (12^{\frac{1}{4}})^{x}\\\\12^{2x-1}=12^{\frac{1}{4}*x}\\[/tex]

Bases are same. So, compare the exponents.

[tex]2x - 1 =\dfrac{1}{4}x[/tex]

Multiply the entire equation by 4

4*(2x - 1) = x

8x - 4 = x

8x     = x + 4

8x -x  = 4

        7x = 4

         x = 4/7

Step-by-step explanation:

Point symmetry refers to an object or shape that forms two similar shapes facing different directions when a point is inserted on the object or shape. This Polygon does not have point symmetry because well it doesn't.

It has line symmetry because you'd be able to draw a line from the point of the arrow downwards and make two halfs of this shape :)

I don't think I need to explain all of them because if you're taking the test you'd probably already learned this stuff. But either ways I understand if you need more clarification, and in case you do just leave a comment and I'll edit this answer :) Have a nice day!

For a transition up you would add the number of h it’s of the transition to the y value and keep the x value the same

the transition would be (6, -5 + 1) = (6,-4)

draw the point at (6,-4) which would be one line above where the dot is now.

Answer:

  x ≈ 57.8°

Step-by-step explanation:

The relevant trig relation is the one that relates the side adjacent to the angle to the hypotenuse and the angle:

  Cos = Adjacent/Hypotenuse

  cos(x) = 8/15

The value of x is found using the inverse cosine function:

  x = arccos(8/15)

  x ≈ 57.8°

Answer:

Devon earned $86.45

Step-by-step explanation:

first, we know that the final price is 960.51 and we know that devon only gets 9% of that.

so we just need to multiply the final price by the percentage

960.51 x 9% = 86.445

then we round up to 86.45

Answer:

Step-by-step explanation:

let x,y be the sides of court.

2(x+y)=90

x+y=90/2=45

y=45-x

xy=500

x(45-x)=500

45x-x²=500

x²-45x+500=0

x²-25x-20x+500=0

x(x-25)-20(x-25)=0

(x-25)(x-20)=0

x=25,20

when x=25

y=45-x=45-25=20

when x=20

y=45-20=25

sides are 25 ft,20 ft.

Answer:

20 by 25 feet

Step-by-step explanation:

A = L·w

P = 2L + 2w

500 = Lw

90 = 2L + 2w

we could solve the first equation for 'w' and then substitute that value into the second equation:

w = 500/L

90 = 2L + 2(500/L)

90 = 2L + 1000/L

90 = (2L² + 1000)/L

multiply each side by L to eliminate it as the denominator

90L = 2L² + 1000

2L² - 90L + 1000

the zeros of this quadratic are 20 and 25

A = 20 x 25 which equals 500

P = 2(20) + 2(25) which equals 90

Answer:Adding 5% interest to an account yearly has the same effect as taking 105% of its current value every year (you're taking all of your money - 100% of it - and adding an extra 5%, getting you 100% + 5% = 105%). This means that, if we started with $1000, after the first year, we'd have

1000(1.05) = $1050

after the second, and third years

1000(1.05)(1.05) = 1000(1.05)² = $1102.50

1000(1.05)(1.05)(1.05) = 1000(1.05)³ ≈ $1157.62

We can see a pattern starting to emerge. The 1000 always stays the same since its our starting value, but the power of the 1.05 goes up by 1 every year. In general, if we call the current value of the account in dollars y and the number of years it's been in the account x, then we can write this pattern generally as

Answer:

28cm

Step-by-step explanation:

To calculate the area of this shape, we need to seperate it into two shapes.

We see that the length of the top shape is 2 CM.  Since the top shape is a square, we know it is a 2x2 shape (because two of the other sides are 2cm.)  The area of the top shape, the square, can be found by performing the formula for calculating area (length x width).  2 x 2 = 4 (duh, haha).  Now, we need to find the area of the bottom shape.  Since we're separating them into two shapes, we need to subtract the length of the first shape and this one.  4 x 6 (the area formula) will give us 24.  Now, we need to add our two shapes to get the area of the entire shape.  24 cm + 4 cm = 28 cm.
