The correct description represent in Venn diagram is;

''Of 9 families, 4 own a pet The Venn diagram represents the families that own a pet.''

What is Venn diagram?

Venn diagram is an illustration that uses circles to show the relationships finite groups of things.

Given that;

Number of family = 9

Number of pets = 4

Now,

In the Venn diagram;

Own pet (circle) contain in number of family (rectangle), that's mean every family has 4 own pet.

Thus, The correct description represent in Venn diagram is;

''Of 9 families, 4 own a pet The Venn diagram represents the families that own a pet.''

Answer:

-0.5

Step-by-step explanation:

Answer:

-0.50

Step-by-step explanation:

4.75  + (-5.25)

Using a number line you can show the sum of points 4.75 and -5.25 is -0.50

1) Starting at 4.75 draw an arrow 5.25 units in the negative direction, arriving at -0.5.

Answer:

the slope=-1 the slope perp=1

Step-by-step explanation:

to find slope perpendicular you just have to multiply your slope by something and have it equal -1

for example

1/2x=-1

the slope perpendicular to a line with the slope of 1/2 would be -2 beacause 1/2x-2=-1

so the slope x perpendicular slope = -1

Answer:

Neither.

Step-by-step explanation:

    Parallel lines have equivalent slopes while perpendicular lines have opposite reciprocal slopes. (Opposite meaning different signs and reciprocal meaning flipped fraction)

[tex]wx:~m=\frac{4-3}{6-(-3)}\\wx:~m=\frac{1}{9}\\\\yz:~m=\frac{-6-(-4)}{8-6}\\yz:~m=\frac{-2}{2}\\yz:~m=-1[/tex]

These lines are neither parallel nor perpendicular.

1. If a polynomial function with rational coefficients has -4 and 8 as roots, it means we can factor this polynomial this way :

(x - (-4))(x-8) = (x+4)(x-8) = x² - 8x + 4x - 32 = x² - 4x - 32

1x² - 4x - 32 is a polynomial function of least degree with rational coefficients that satisifies the given conditions. The leading coefficient here is 1, we call this a monic polynomial.

2. There may be something missing in the question here

3. We can use the factoring techniques to find the roots :

x^3 - 5x² + 9x - 45 let us group x^3 with -5x² and 9x with -45 :

(x^3 - 5x²) + (9x - 45) = x²(x - 5) + 9(x - 5)

We can notice now that there is a common factor : (x-5) this allows us to factor again by (x-5) :

Y = (x-5)(x²+9)

This is the maximum we can do on R, but on C the set of complex we can still factor again.

x² + 9 has a negative discriminant : Δ = b² - 4ac where b = 0 , a = 1, c = 9

Δ < 0, Δ = - 36

Applying the formulas for the roots x1 and x2 we get x1 = -3i, and x2 = + 3i

Y = (x-5)(x-3i)(x+3i)

So the solution is S = {5, 3i, -3i} the three roots of the function.

Answer:

5

Step-by-step explanation:

q = 6

r = 19

4q^2

= 4 x q^2

= 4 x 6^2

= 4 x 6 x 6

= 144

qr

= q x r

= 6 x 19

= 114

qr + 25

= 114 + 25

= 139

4q^2 - ( qr + 25 )

= 144 - 139

= 5

D- Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen.

Step-by-step explanation:

The situation is an example of an observational study is "Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen:.

When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.

For example: Consider someone standing on a popular street in a New York neighborhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.

As we know that in an observational study, the sample whose test/survey is been taken is completely random.

Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favorite brand of toothpaste".

Answer:

D. y = 4x - 6

Step-by-step explanation:

The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,

Therefore,

m₁ × m₂ = -1

Using the 2 coordinates of MN let's find the slope,

(-7, 6)(5, 3)

Therefore,

m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4

The equation that represent a line perpendicular to the line MN is

y = 4x - 6 because the slope slope(m₂) is 4.

From our formula,

4 × - 1 / 4 = - 1

So, option D meets the requirement.

D. y = 4x - 6

Step-by-step explanation:

Answer:

sqrt(x) where x is between 81 and 100; example sqrt(88). See explanation for more examples.

Step-by-step explanation:

9=sqrt(81) and 10=sqrt(100)...

So the square root(x) is between 9 and 10 if x is between 81 and 100.

Here are examples:

sqrt(82)

sqrt(83)

sqrt(85.6)

sqrt(92)

sqrt(94)

sqrt(97)

sqrt(99)

sqrt(99.6)

So again the answer is just anything in form sqrt(x) where x is between 81 and 100. The reasoning is because sqrt(81)=9 and sqrt(100)=10 which puts the values we stated between those values.

Answer:

140%

Step-by-step explanation:

(24-10) / 10 = 14/10 = 140%

Answer:

140%

Step-by-step explanation:

A change from 10 to 24 represents a positive change (increase) to 140%.

Percent change = New-Old/Old x 100%

Percent change = 24-10/10 x 100% =

14/10 x 100 = 140% (increase)

Where 10 is the old value and 24 is the new value. In this case, we have a positive change (increase) of 140 percent because the new value is greater than the old value.

Answer:

(-1)

Step-by-step explanation:

y = ?

Answer :

-4(y - 2) = 12

(-4 . y) - (-4 . 2) = 12

-4y - (-8) = 12

-4y + 8 = 12

-4y = 12 - 8

-4y = 4

y = -4/4

y = (-1)

-4(y - 2) = 12

-4y + 8 = 12

-4y = 12 - 8
