The correlation of the rates of return between x and y is the closest to = 0.4

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate). It's a common tool for describing simple relationships without making a statement about cause and effect.

Calculation for the correlation of the returns,

Using this formula,

Covariance of the returns = Correlation coefficient between the returns*Stock returns standard deviation*Mod T Stock returns standard deviation

The sample standard deviations of the rates of return for stock x and stock y were 0.20 and 0.12

The sample covariance between the returns of x and y is 0.0096.

Let plug in the formula

Covariance of the returns = Correlation * (0.20) * (0.12)

0.0096 = Correlation * (0.20) * (0.12)

0.0096 = Correlation * 0.024

0.0096 / 0.024 = Correlation

0.4 = Correlation

Correlation = 0.4

Therefore,

The correlation of the rates of return between x and y is the closest = 0.4

Answer:

2500

Step-by-step explanation:

Dimensions of first level

Length = Breadth = 75 ft (since it is a square)

It is assumed that a person will occupy \(2.25\ \text{ft}^2\)

Area of first level

\(75\times 75=5625\ \text{ft}^2\)

When the area of the level is divided by the area of one person then we will get the number of people that can occupy the room or the number of tickets that can be sold.

\(\dfrac{5625}{2.25}=2500\)

The number of tickets that can be sold for the first level is 2500.

Answer: 30 cm

Step-by-step explanation: 5 × 2 = 10

5 + 5 + 10 + 10 = 30

Ingrid's baby brother's current weight in ounces is 102 + 19 = 121 ounces.

Ingrid's Baby brother weighed 6 pounds 6 ounces when he was born, which is equivalent to 6 x 16 + 6 = 102 ounces.

He has gained 1 pound 3 ounces since then, which is equivalent to 1 x 16 + 3 = 19 ounces.

by solving the equation.

Therefore, Ingrid's baby brother's current weight in ounces is 102 + 19 = 121 ounces.

ANSWER

520 pints = 0.89 barrels

EXPLANATION

First we have to know how many quarts are 520 pints. If 2 pints equals to one quart, then:

Now we have to transform this to gallons. If 4 quarts is 1 gallon, then:

And finally tranform from gallons to barrels. If 73 gallons is one barrel, then:

The height is 230 feet after 9.125 seconds.

We have the  equation that describes the height of the object as a function of time as:

h(t) = -16t^2 + 145t + 2

We input the values and simplify:

-16t^2 + 145t + 2 = 230

-16t^2 + 145t - 228 = 0

we can use the quadratic formula, to solve this quadratic equation,

t = (-b ± √(b^2 - 4ac)) / 2a

where a = -16, b = 145, and c = -228.

t = (-145 ± √(145^2 - 4(-16)(-228))) / 2(-16)

t = (-145 ± √ (21025)) / (-32)

t = (-145 ± 145) / (-32)

t = 0.625 seconds or t = 9.125 seconds

In conclusion, the height is 230 feet after 9.125 seconds.

Answer:

n/4=6n=4

Step-by-step explanation:

The trigonometric expression (sec x - csc x) / (1 - tan x) is equivalent by trigonometric formulas and algebra properties to - sin x.

Herein we find a trigonometric expression that must be rewritten in terms of sin x by means of trigonometric formulas and algebra properties. The original expression is shown below:

(sec x - csc x) / (1 - tan x)

First, the original expression is written:

(sec x - csc x) / (1 - tan x)

Second, use the definitions of secant, cosecant and tangent:

[(1 / cos x) - (1 / sin x)] / [1 - (sin x / cos x)]

Third, use algebraic properties to simplify the expression:

[(sin x - cos x) / (sin x · cos x)] / [(cos x - sin x) / cos x]

[(sin x - cos x) · cos x] / [sin x · cos x · (cos x - sin x)]

- sin x

Answer:

equation of the line is y=x+1

Step-by-step explanation:

the equation of a line has the form y = mx + b

while m is for the slope and b is for the y-intercept.

you can see from the graph that the line intercepts the y-axis at y=1 this is the b.

you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:

in our case it will be:

\(m=\frac{4-2}{3-1} = \frac{2}{2}=1\)

then just substitute the values for m and b.

The explicit formula that represents the nth term of the sequence will be aₙ = 18 - 7n.

A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The arithmetic sequence is given below.

11, 4, -3, .....

The first term is 11. And the common difference is given as,

d = 4 - 11

d = - 7

The explicit formula that represents the nth term of the sequence is given as,

aₙ = a₁ + (n - 1)d

aₙ = 11 + (n - 1)(-7)

aₙ = 11 - 7n + 7

aₙ = 18 - 7n

The explicit formula that represents the nth term of the sequence will be aₙ = 18 - 7n.

Answer:

Step-by-step explanation:

To find the equation of a line that is perpendicular to a given line and passes through a specific point, we need to follow a few steps:

Find the slope of the provided line.

The point-slope form of a line is given by: y - y1 = m(x - x1), where (x1, y1) represents the given point.

Substituting the values, the equation of the perpendicular line becomes:

y - 5 = (-1/m)(x - 2)

Simplifying the equation further, we can rewrite it in point-slope form:

y - 5 = (-1/m)x + (2/m)

Answer:

3 landscaping, 3 tutoring

Step-by-step explanation:

This is a system of equations.

Let T = number hours tutoring and L = number hours landscaping.

T + L = 10

137 = 14T + 13L

Now solve the system of equations.

We can rearrange the first equation so that T = 10-L. Substitute that in the 2nd equation.

137=14(10-L) + 13L

137 = 140-14L + 13L

-3=-L

3=L

He worked 3 Landscaping Hours. Substitute back into the original equation to solve for T (tutoring hours).

T+L = 10

T+3 = 10

T = 7.

We worked 7 tutoring hours.

Now double check with the earnings equation.

137 = 14T + 13L

137 = 14*7+ 13*3

137 = 98 + 39

137=137
