To decide whether to use the normal or the Student’s t distribution, for an x distribution that is mound-shaped:

Use the normal distribution if the standard deviation is known. Use the Student's t - distribution when the standard deviation is not known.

A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution.

It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution is depicted graphically as a bell curve.

For small sample numbers or unidentified variances, population parameters are estimated using a form of probability function called a t-distribution.

Hence t-distribution is suitable when the variance which is standard deviation squared is unknown

The part (a) is not correct i.e. The slope is 3, which indicates that a mouse's weight should increase by about 3 grams for each additional millimeter of tail length.

What is Regression analysis ?

Regression analysis is the process of determining how one or more variables and the outcome variable relate to one another. Risk factors, co-founders, and the outcome variable are all referred to as predictors or independent variables. The result variable is sometimes referred to as the dependent or response variable. Regression analysis displays the dependent variable as "y" and the independent variables as "x".

Given, tail length = (3 × weight) + 20

(a) Here, The slope is 3 which indicates that a mouse's length is the sum of 3 times the weight and 20. So, the statement is not correct.

(b) If weight is 38 gm, then

    tail length = 38 × 3 + 20

                     = 114 + 20 = 134mm.

So, the statement is correct.

(c) We've  tail length = (3 × weight) + 20

we can see that the relationship between the two is positive because when the weight is increased, the tail length also increases.

So, the given statement is correct.

(d) The slope is 3 when the tail length is being measured in millimeters.

Now, If we measure it in centimeter = 3/10 = 0.3 cm

∵ 1 mm = 1/10 cm.

So, the given statement is correct.

(e) when a mouse has weight of 29 grams and tail length of 100 mm.

    When the weight is 29 grams, it should have tail length as :

             tail length = 29 × 3 + 20

                              = 107 mm.

  but, tail length is given as 100 mm.

So, the residual for the mouse is -7 i.e. (100 - 107)

Step-by-step explanation:

Subtract 34 from 246 for the number of sodas sold.

The value of the function (f⋅g)(3) = 1

The characteristic that every input is associated with exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs. It is denoted by the letter f or f(x).  

Here we have

f(x) = − 3x − 2  

g(x) = − x + 2

=> (f · g) = f(g(x))

Now Take x = − x + 2 in f(x)

=> f(g(x)) =  − 3(− x + 2)x − 2  

=  3x − 6 − 2      

=  3x − 8  

From the above calculations,

(f⋅g)(x) =  3x − 8    

Now we need to calculate the value of (f⋅g)(3) as given below

=> (f⋅g)(3) =  3(3) − 8 = 9 − 8 = 1

Comparing the number of same-size bottles drank to the amount of ounces of water consumed. So, option c is correct.

When the ratio of the output to the input stays constant at every given point along the function, the rate of change is said to be constant. A linear function's change will occur at a steady rate.

Comparing the number of same-size bottles drank to the amount of ounces of water consumed.

We say there is a constant rate of change when a quantity varies uniformly in relation to the change of another quantity.

Therefore, there is a constant rate of change if one quantity is directly proportionate to the other.

The number of identical-sized bottles drank is directly proportionate to the number of ounces of water consumed. As a result, the rate of change in water ounces in relation to the quantity of identical-sized bottles is constant.

$1,556.72 is required to deposit in the account each month.

72% of interest is earned.

a)

It is a classic Ordinary Annuity saving plan. The general formula is

FV = P((1+r)^n-1)/r)--------(1)

where  

FV is the future value of the account.  

P is the monthly payment (deposit).

r is the monthly percentage yield presented as a decimal.

n is the number of deposits (= the number of years multiplied by 12, in this case).

From this formula, you get the monthly payment:

P=FV(r/(1+r)^-1)----------(2)

Under the given conditions,

FV = $800,000

r = 0.04/12

n = 25*12.  

So, according to formula (2), the monthly payment is

P=800000(0.04/12(1+0.04/12)^25*12-1)

P=800000(0.003/1.713)

P=$1.556.72

Note that of the projected $800,000 the total you deposit will be only  25*12 times $1.556.72 i.e. about 25*12*1.556.72 = 467016 dollars.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Data provided in the question:

Total amount to be invested = $140000

Stock                          X       Y

Expected return       14%     10%

Beta                          1.42     1.18

Expected return of portfolio = 17.6%

Now,

let the weight invested n stock X be W

therefore,

Weight of Stock Y = 1 - W

thus,

( W × 14% ) + (1 - w) × 10% = 17.6 %

14W + 10% - 10W = 17.6%

4W = 7.6

W = 1.9

Therefore,

weight of Y = 1 - 1.9 = -0.9

Amount investment in Sock Y = Total amount to be invested × Weight

= 140,000 × ( - 0.9 )

9x − 3 − 15x + 9 = − x − 6

9x − 15x + x = 3 − 9 − 6

− 5x = − 12

5x = 12

x = 12/5

Answer:

Step-by-step explanation:

Given equation:

[tex]3(3x-1)-3(5x-3)=-(x+6)[/tex]

Distribute:

[tex]\implies 3 \cdot 3x + 3 \cdot (-1) - 3 \cdot 5x - 3 \cdot (-3)=-x-6[/tex]

[tex]\implies 9x-3-15x+9=-x-6[/tex]

Collect and combine like terms on the left side of the equation:

[tex]\implies 9x-15x+9-3=-x-6[/tex]

[tex]\implies -6x+6=-x-6[/tex]

Add 6x to both sides:

[tex]\implies -6x+6+6x=-x-6+6x[/tex]

[tex]\implies 6=5x-6[/tex]

Add 6 to both sides:

[tex]\implies 6+6=5x-6+6[/tex]

[tex]\implies 12=5x[/tex]

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

f(x) = 3x² + 2x - 1

Now , to calculate the value of f ( 5 ) , substitute the value of x as 5

So , when x = 5 , the equation will be

f(x) = 3x² + 2x - 1

f ( 5 ) = 3 ( 5 )² + 2 ( 5 ) - 1

On simplifying the equation , we get

The value of f ( 5 ) = 3 x 25 + 10 - 1

The value of f ( 5 ) = 75 + 10 - 1

The value of f ( 5 ) = 85 - 1

The value of f ( 5 ) = 84

Therefore , the value of f ( 5 ) is 84
