The type of statements that can be used to justify the steps of proof are:

This refers to the type of statement that is used to explain the sequence of steps that are contained in a proof.

Hence, we can see that in order to justify a proof mathematically, it is important to show the corollaries that state the steps used and also the conjectures made which are options A and B.

Answer:

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6

Answer:

[tex]F(2)=C-12[/tex]

Step-by-step explanation:

Given: [tex]F(x)=x^2-8x+C[/tex]

To find: value of [tex]F(2)[/tex]

Solution:

[tex]F(x)=x^2 - 8x + C\\=x^2-2(4)x+C[/tex]

Add and subtract [tex]4^2[/tex] in the left side of the equation

[tex]F(x)=x^2-2(4)x+4^2-4^2+C[/tex]

Use formula: [tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]F(x)=(x-4)^2-4^2+C\\=(x-4)^2+C-16[/tex]

Put [tex]x=2[/tex]

[tex]F(x)=(x-4)^2+C-16\\F(2)=(2-4)^2+C-16\\=4+C-16\\=C-12[/tex]

Answer:

D) The price of fish per pound

Step-by-step explanation:

A continuous data is one which can take any value . it can have even value between any two consecutive number.

Example :

continuous data can have value between 4 and 5 like 4.5 4.001 and so on.

Discrete data is one which can be counted such as number of flowers, no of cars in parking.

it can take value such as 1,2, 12, 66  etc.

____________________________________________

Let go through the option

A) The number of times you flip a coin

We can count the number of times a coin is flipped .

Like 2 times, 3 times and hence it is discrete data and not a continuous one.

B) The number of students in a classroom

Student in a classroom can also be counted.

in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.

hence it is discrete data and not a continuous one.

C) The number of chocolate candies in a box

Again, chocolate number can be counted .

Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and

hence it is discrete data and not a continuous one.

D>The price of fish per pound

Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555

hence it is a continuous data.

Based on above discussion

continuous data is represented by The price of fish per pound

Answer:

Step-by-step explanation:

-2 < n+3 ≤ 4

Make two separate equations,

-2 < n+3

Subtract 3 from both sides,

-2-3 < n + 3  -3

-5 < n

So, value of n should be greater than (-5)

n +3 ≤ 4

Subtract 3 from both sides

n ≤ 1

So, n value should be less than or equal to 1

So, n value should be greater than -5 and less than or equal to 1

n= { -4, -3 , -2 , -1 ,0 ,1 }

Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = [tex]\frac{1}{3}[/tex][tex]\pi[/tex]r²h

V = [tex]\frac{1}{3}[/tex](3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

113.04 = [tex]\frac{4}{3}[/tex](3.14)r³

113.04 = 4.19r³

26.98 = r³

Answer:

m=-2

Step-by-step explanation:

Take 2 points (0,0) and (-3,6)

m(slope)= m = rise/run = y2 - y1/ x2 - x1

y2-y1= 6-0=6

x2-x1 = -3-0 = -3

m=6/-3 = -2

y=-2x

Answer:

y = 90 degrees

Step-by-step explanation:

The line in the middle of the triangle is a perpendicular bisector since it splits the angle at the top in half.  That means it forms a 90 degree angle where it intersects the base

y = 90 degrees

The required value of the expression [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Given that,
The expression [tex]\frac{a + 2bc}{3a}[/tex]  is given, The value of the expression at a = 4, b = -5, and c = -7 is to be determined.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given expression
=  [tex]\frac{a + 2bc}{3a}[/tex]
At  a = 4, b = -5, and c = -7
[tex]= \frac{4 +2 * -4 * -5 }{3 * 4 } \\= 74 / 12\\= 37 / 6[/tex]

Thus, the required value of the expression  [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Answer: 3

Step-by-step explanation:

Answer:

X = C - By over A which also is A ≠ 0

Y = C - Ax over B which is also B ≠ 0

Step-by-step explanation:

Solve for x

First subtract "By" from both sides:

Ax + By - By = C - By

Then simplify,

Ax = C - By

Divide both sides by A:

Ax / A = C/A - By/A ; A≠0

Then simplify:

X = C - By over A ; A ≠ 0.

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

Solve for y

First subtract "Ax" from both sides:

Ax - By - Ax = C - Ax

Simplify,

By - C = Ax

Then divide both sides by B:

By/B = C/B - Ax/B ; B ≠ 0

Simplify:

Y = C-Ax / B ; B ≠ 0.

Answer:

The correct option is C.

C) The range represents the number of users each month for 36 months

Step-by-step explanation:

We have been given that:

x-axis ⇒ Number of Months

y-axis ⇒ Number of Users

x-axis values = 0 to 36

y-axis values = 0 to 60

We have a function which is represented by a straight line from (0,0) to (36,54).

We have to find the RANGE of the function.

Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x

As total number of months = 36

Range is the set of all values of y (Number of Users) for each month for a period of 36 months.

Hence, the correct option is C.

Answer:

m+n=23

Step-by-step explanation:

the modes m and n have to be data points more than 1 time, but equal

if there are 7 data points, then there are 4 unknown left/2 2 each

(2m-3+m+12+3n+2+m+m+n+n)/7=18

(3m+9+3n+2+m+m+n+n)/7=18

(5m+5n+11)/7=18

(5/7)*m+(5/7)*n+11/7=126/7

(5/7)*m+(5/7)*n=115/7

5m+5n=115

m+n=115/5

m+n=23
