Answer: 68/7

Step-by-step explanation:

given data:

(3/2) of (4/7) multiplied by [(10x3)-(8x2)]​

first we break it down into smaller sets.

= ( 3/2 ) * (4/7 )

= 6/7 * [(10x3)-(8x2)]​

we open the brackets

=  6/7 * (10x3)-(8x2)

= 6/7 * 30 –16

= 6*30/7 –16

= 180/7 – 16

= 68/7

Answer:

0.31084

Step-by-step explanation:

When given a question where by a random sample is chosen for the population, the z score formula used =

z = (x-μ)/Standard error

where x is the raw score

μ is the population mean

Standard error = σ/√n,

σ is the population standard deviation

n = number of samples

For x = $114,000, μ = $115,000, σ = 25,000, n = 100

z = (x-μ)/Standard error

= z = (x-μ)/ σ/√n

z = 114,000 - 115,000/ 25,000/√100

= -1000/25,000/10

= -1000/2500

z = -0.4

Determining the probability value from Z-Table:

P(x = 114000) = P(z = -0.4)

= 0.34458

For x = $116,000, μ = $115,000, σ = 25,000, n = 100

z = (x-μ)/Standard error

= z = (x-μ)/ σ/√n

z = 116,000 - 115,000/ 25,000/√100

= 1000/25,000/10

= 1000/2500

= 0.4

Determining the Probability value from Z-Table:

P(x = 116000) = P(z = 0.4)

= 0.65542

The probability that the sample mean selling price was between $114,000 and $116,000 is calculated as

= P(114,000< x < 116,000)

= P(-Z<x<Z)

= P(-0.4<x< 0.4

= 0.65542 - 0.34458

= 0.31084

Therefore, the probability that the sample mean selling price was between $114,000 and $116,000 is 0.31084

Answer:

B

Step-by-step explanation:

2x – y = (3/4)x + 6.

or, 2x - (3/4)x = y + 6.

or, (8x -3x)/4 = y + 6.

or, 5x/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.

or, x = (4y + 24)/5.

Therefore, x = 4(y + 6)/5.

Answer:

Yes

Step-by-step explanation:

If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.

The slope of AC is:

m = (3 − 3) / (6 − 0) = 0

The slope of BD is:

m = (0 − 6) / (3 − 3) = undefined

The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.

Specifically, AC is horizontal and BD is vertical.

The area of a rectangle is a natural number, an integer and a rational number.

Step-by-step explanation:

The area of a rectangle is a member of the following three subsets of real numbers:

(i) Natural numbers ([tex]\mathbb{N}[/tex]) - The area of the rectangle has no decimal parts and is positive.

(ii) Integer ([tex]\mathbb{Z}[/tex]) - The area of the rectangle has no decimal parts.

(iii) Rational numbers ([tex]\mathbb{Q}[/tex]) - The area of the rectangle can be obtained by dividing a natural number by other natural number. For instance:

[tex]\frac{36}{2} = 18[/tex]

In a nutshell, the area of a rectangle is a natural number, an integer and a rational number.

Three flavors of juice are offered at a school cafeteria.

The given table:

Orange Grape   Cherry

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-7,1)

and slope/m=3

The equation of the line is

Answer:

[tex]h(x)=\frac{1}{4}|x|[/tex]

Step-by-step explanation:

In order to vertically stretch a function, we just need to multiply the function by our stretch factor.

So, we have the function:

[tex]g(x)=|x|[/tex]

We want to find the equation of this function vertically shrunk by a factor of 1/4. So, multiplied the function by 1/4:

[tex]h(x)=\frac{1}{4}|x|[/tex]

And this will be our answer :)

[tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex]

[tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex].

Step-by-step explanation:

The given vectors are

[tex]\vec{a}=<-3,-6,2>,\vec{b}=<1,1,2>[/tex]

Now,

[tex]|\vec{a}|=\sqrt{(-3)^2+(-6)^2+(2)^2}[/tex]

[tex]|\vec{a}|=\sqrt{9+36+4}[/tex]

[tex]|\vec{a}|=\sqrt{49}[/tex]

[tex]|\vec{a}|=7[/tex]

[tex]\vec{a}\cdot \vec{b}=(-3)(1)+(-6)(1)+(2)(2)[/tex]

[tex]\vec{a}\cdot \vec{b}=-3-6+4[/tex]

[tex]\vec{a}\cdot \vec{b}=-5[/tex]

The scalar projection of b onto a is

[tex]comp_ab=\left(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|}\right)[/tex]

[tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex]

Vector projection of b onto a is

[tex]Proj_ab=\left(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|}\right)\left(\dfrac{\vec{a}}{|\vec {a}|}\right)[/tex]

[tex]Proj_ab=\left(\dfrac{-5}{7}\right)\left(\dfrac{<-3,-6,2>}{7}\right)[/tex]

[tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex]

Therefore, scale and vector projections of b onto a are [tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex] and  [tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex] receptively.

Answer: C

Step-by-step explanation:

The difference between an equation and expression is the equals sign. A simple way to tell of an expression is an equation is if there is an equal sign. If there is an equal sign, then it is an equation. If not, it is an expression.

Since this problem is asking for expression, it would be easiest to find an answer choice that doesn't include the word "_____is _____". This is a way to say _____ is equal to ____.

Let's go through each of the answer choices and write the equation/expression for it.

A. Equation

(4+x)/2=12

---------------------------------------------------------------------------------------------------------

B. Equation

p-1=14

---------------------------------------------------------------------------------------------------------

C. Expression

3c-9

---------------------------------------------------------------------------------------------------------

D. Equation

9m=36

---------------------------------------------------------------------------------------------------------

There is no indication that the expression is equal to anything, therefore C is the correct answer.

Answer:

9

Step-by-step explanation:

substitute the x which is x= 2, so

f(2)= (2+1)^2

=(3)^2

=9

The value of f(2) if f(x) = (x+1)² is 9.

A function from set X to set Y is created by assigning an element from set Y to each element in set X.
The function's domain and codomain are respectively referred to as the sets X and Y and considered as a whole.

A function, its domain, and its codomain are denoted by the notation  f:X→Y.  

The image of x under f or the value of f applied to the input x are terms used to describe the value of a function at an element x of X, indicated by the notation f(x).

The functions can also be referred to as maps or mappings.

In this question;

Given function is f(x) = (x+1)²

We have to find the value of f(2) that means we have to put 2 in the place of x in f(x)

Thus,

⇒f(x) = (x+1)²

⇒f(2)= (2+1)²

⇒f(2)= 3²

⇒f(2) = 9

Hence, the value of f(2) if f(x) = (x+1)² is 9.

Just multipley 42 by 7

Answer:

a) Here we have:

"In Family A, the youngest child is 7 years younger than the oldest, who is 18"

Let's define:

Y = age of the youngest child.

O = age of the oldest child.

Then we know that:

Y = O - 7

O = 18

Then we can replace the second equation into the first one:

Y = 18 - 7 = 11.

b) Here we have:

"In Family B, the middle child is 5 years older than the youngest child."

Let's define:

Y = age of the youngest child.

M = age of the middle child.

Here we have only one equation:

M = Y + 5.
