Answer:

1. 42 people can be seated

2. 16 tables should be used.

Step-by-step explanation:

Part 1:

Since we are given the function, p(n) = 4n + 2, we need to plug in 10 to "n." This is because "n" represents the number of tables as stated on the top of the pciture. And "p(n)" represents the number of people that can be seated.

p(n) = 4(10) + 2

p(n) = 40 + 2

p(n) = 42

Part 2:

For this question, since we are given 65 as the total number of people that can be seated, we would plug in 65 in "p(n)", to result in the following equation.

p(65) = 4n + 2

Then solve the equation and use the property of inverse operation.

65 = 4n + 2

65 - 2 = 4n + 2 - 2

63 = 4n

63/4 = 4n/4

15.75 = n

Although we're given 15.75 as the number of tables that should be used, we can't really have a 0.75 of a table, so we would round 0.75 to 1.

15 + 1 = 16

16 tables are required.

Answer:

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:

Step-by-step explanation:

Answer The correct answer to the following question is not provided U need to do it your self lol jk answer is d

Step-by-step explanation:

Answer: Line 1: (2, 3) , (4, 12)

m = (12 - 3)/(4 - 2) = 9/2  This is the slope of the line

y = (9/2)x + b

3 = (9/2)(2) + b

3 = 9 + b

b = -6

y = (9/2)x  - 6

Line 2: (5, 10) , (14,8)

m = (8 - 10)/(14 - 5) = -2/9

this slope is the opposite sign, and inverse of the first equation's slope.  Therefore, the line is perpendicular.

y = mx + b

8 = (-2/9)(14) + b

8 = -28/9 + b

11.11 = b

y = (-2/9)x + 11.11

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.

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.

Step-by-step explanation:

-5g -6

Let g= -2

-5 (-2) -6

Multiply

10 -6

4

Answer:

A. 4

Step-by-step explanation:

So, we have an equation with a variable (g), and they've given us the value of g to be -2. All we have to do at this stage is plug in the value of g into the equation.

-5g-6 (g=-2)

-5(-2)-6

10-6=4

Doing the math by plugging in -2, you would get your answer to be 4. Let me know if you see any errors, and if you have any further questions at all.

Step-by-step explanation:

Answer:

We know that,

[tex]a^{x} *a^{y} =a^{x+y}[/tex]

[tex]a^{-x} =\frac{1}{a^{x} }[/tex]

[tex]\frac{1}{a^{-x} } =a^{x}[/tex]

Let's solve now

[tex]\frac{3^{4} *5^{2} }{5^{8}*5*3^{-1} }[/tex]

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:

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.

Answer:

D. y = 4x - 6
