The process of correcting data to reduce them to the sample scale by subtracting the sample mean and dividing by the standard deviation- Options Generalization Scale transformation Standardization Variable re – specification

Answers

Answer 1
Answer: Standardization 

Or to produce the one of the statistical concepts, the z-score. The z-score is yielded when the sample mean deducts the observed sample score and is divided by the standard deviation. This is used to standardize the scale into numbers from or before 0.

=>32 - 6x + 7x = -15 + 28
=>32 - 6x + 7x + 15 -28 =0
=>32 -28 + 15 -6x + 7x =0
=>19 + x =0
=>x = -19

Ten times the sum of half a number and 6 is 8

Answers

Answer:
The number is -10.4

Explanation:
Assume that the number we are looking for is x.

Now, we want to get 10 times te sum of half the number and 6 and equate this expression to 8. Then we can solve for x

Let's take this step by step:
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8

Now we can solve for x as follows:
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4

Hope this helps :)

The number we want to find is -10.4

Solving linear equation mean calculating the unknown variable from the equation.

Let the linear equation : y = mx + c

If we draw the above equation on Cartesian Coordinates , it will be a straight line with :

m → gradient of the line

( 0 , c ) → y - intercept

Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :

\large {\boxed {m = (y_2 - y_1)/(x_2 - x_1)}}

If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :

\large {\boxed {y - y_1 = m ( x - x_1 )} }

Let us tackle the problem.

Let :

The number = X

If ten times the sum of half a number and 6 is 8 , then :

10 * ( (1)/(2) X + 6 ) = 8

( 10 * (1)/(2) X ) + ( 10 * 6 ) = 8

5 X + 60 = 8

5 X = 8 - 60

5 X = -52

X = -52 / 5

\large {\boxed {X = -10.4} }

What is the future value in one year of an account that has $450 deposited in it, and earns a 2.1% annual interest rate?

Answers

The interest is $9.45

Final answer:

The future value of an account in one year with a $450 deposit and a 2.1% annual interest rate is $459.45.

Explanation:

The question asks about the future value of an account with a certain initial deposit and an annual interest rate. The future value can be calculated using the formula for simple interest: FV = P * (1 + r * t) where FV stands for Future Value, P stands for the initial Principle amount, r is the annual interest rate and t stands for time.

Applying this formula for your question, the initial deposit P is $450, the interest rate r is 2.1% or 0.021 (in decimal form), and the time t is 1 year.

So, FV = $450 * (1 + 0.021*1) = $450 * (1.021) = $459.45.

Therefore, the future value in one year for an account that was originally deposited with $450 and has a 2.1% annual interest rate is $459.45.

You are dealt one card from a 52-card deck. Find the probability that you are dealt: a numbered card or a spade

Answers

in 52-card deck there are 36 numbered card and 52/4=13 spade card
 so probability that you are dealt a  numbered card is 36/52 =9/13  a spade card is 13/52=1/4
So you start out with the 52 original cards. You know what 13 cards are spade shaped, and there are 10 numbered cards in each symbol. In total, 40 out of 52 cards are numbered, and 13 out of 52 are spade symbol. Now 10 out each symbol are numbered, start out with that. That equals 30 numbered cards. Now add the entire spade minideck, and you have 43 cards being the possibility. In numerical form, 43 out of the 52 cards are possible to be chosen. In fraction form, 43/52 will be your answer.
