Given that,

The points are (4,4) and (8,3)

To find,

The slope of the line.

Solution,

The slope of a line is given by the formula as follows :

m=\dfrac{y_2-y_1}{x_2-x_1}

Put x₁ = 4, y₁ = 4, x₂ = 8 and y₂ = 3

m=\dfrac{3-4}{8-4}\\\\=\dfrac{-1}{4}

So, the slope of the line is \dfrac{-1}{4}.

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6
Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

so

60=\frac{(88+94+92+98+x)}{5}

solve for x

Combine liker terms in the right side  

60=\frac{(372+x)}{5}

Multiply by 5 both sides

300=372+x

Subtract 372 both sides

300=372+x

x=-72 -----> this is not make sense

The grade cannot be a negative number

so

For x=0

The minimum average grade is

\frac{(372)}{5}=74.4

An experiment has conducted a single-factor completely randomized design with three levels of factors and five replicates. The c
Ad libitum [116K]

Answer / Step-by-step explanation:

To properly understand the principle behind the solving of this question, it would be necessary to define and go through some basic terms and their definition.

Therefore to start with, a completely randomized single factor is a type of experiment in which One factor of two or more levels has been manipulated. e.g, the experiment may be investigating the effect of different levels of cost, expenditure or different advertisements

Also, it should be noted that in the area of groping of the experiment, At this point, Each group of different level receives one of the a levels of the independent variable with participants being treated identically in every other respect. The two-group experiment considered previously is a special case of this type of design.

Consequentially, the answer to the narrative of the question would then be:

N= 3 factors levels x 5 replicates = 15

Degrees of freedom for the factor:  a – 1 = 3 – 1 = 2

Degrees of freedom Total = 15 – 1= 14

Degrees of freedom error = Total – factor = 14 – 2 = 12

Bounds of P-value for F = 2.91 with 2 and 12 degrees of freedom are

= 0.01 < P < 0.05
