Answer:

Systematic sampling

Step-by-step explanation:

An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.

For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10

He will have to select ;  ( x / n )^th of the sampling frame for best results

Answer:

At most, 8 apples and apricots can be arranged at 4 plates, so that each plate contains 2 apples and 5 apricots.

Step-by-step explanation:

they are asking for the GREATEST amount of plates, but there are less apples than apricots so we must find the GCF, which is 4. then you divide the amount of apples by 4 as well as the amount of apricots by 4.

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

The required stories that are models of the given expression  -6 + 3x = 2 + 4x are given in A and B. Both options are correct.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Option A,

At 5 p.m., the temperatures recorded at two weather stations in Antarctica are -6 degrees and 2 degrees. The temperature changes at the same constant rate, x degrees per hour, throughout the night at both locations. The temperature at the first station 3 hours after this recording is the same as the temperature at the second station 4 hours after this recording.

So from the above statement,
The equation modeled is given as
-6 + 3x = 2 + 4x

The above expression is equivalent to the given statement. So story mentioned in option A matches the given equation.

Similarly,
The equation formed in Option B also matches the given equation.

Thus, both options are correct.

Answer:

10 more packs

Step-by-step explanation:

400 sweets bought 25 such packs = 400*25=10000

2000 each one gets 7 = 2000*7=14000

14000-10000=4000

4000/400 is 10.

So 10 more packs.

Hit the crown :D

Answer:

Step-by-step explanation:

400 sweets in a pack * 25 packs = 10,000 sweets

2000 kids * 7 sweets = 14,000

We need 4,000 more sweets. That would be 10 packs more  since there are 400 sweets in a pack.

Answer:

Slope: 1

Y intercept: 2 or (0,2)

Equation: y=x-2

Step-by-step explanation:

add 4 i guess. i dont really know

Answer: 4, 5, 6, 7

Step-by-step explanation:

Let’s break this apart into 3 < y and y <= 7.

We can rewrite 3 < y as y > 3, and we also have that y <= 7.

This is equivalent to the verbal expression y is greater than 3 and less than or equal to 7.

We can then conclude that y must be between 4 (since that is the first number greater than 3) and 7 (since y includes 7).

Therefore, y can be 4, 5, 6, or 7!

a. It is a binomial

b. It is a trinomial

c. It is a monomial

d. It is a trinomial

e. It is a binomial

To answer the question, we need to know what polynomials are

Polynomials are algebraic expressions that contains variables and coefficients.

a.

2 - x² + 4x + x² = 2 - x² + x² + 4x

= 2 - 0 + 4x

= 2 + 4x

Since it has two terms, it is a binomial

b.

x - 5x² + 3 - 2 = x - 5x² + 1

= - 5x² + x + 1

Since it has three terms, it is a trinomial

c.

x² - x² + x² - x² + 3 = 0 + 0 + 3

= 3.

Since this contains a single term, it is a monomial

d.

7x - x² + x³ + 4x² = x³ + 4x² - x² + 7x

= x³ + 3x² + 7x

Since it has three terms, it is a trinomial

e.

-6x - x² + 6x - 4x = -6x - x² + 2x

= - x² + 2x - 6x

= - x² - 4x

Answer:

4/24

Step-by-step explanation:

Because 1/6 is 4/24 simplified.

To prove this, all you have to do is try simplifying 4/24 yourself. To do that, we are going to use 4 to divide both the numerator and the denominator because 4 is a common factor of 4 and 24.

(To simplify a fraction, you divide both the numerator and denominator by a common factor)

So 4 divided by 4 is 1, and 24 divided by 4 is 6

Answer:

y = x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line

m = [tex]\frac{2-0}{0+2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

The line crosses the y- axis at (0, 2) ⇒ c = 2

y = x + 2 ← equation of line

Answer:

1.) 2/5

2.) -7/5

Step-by-step explanation:

Slope Formula: m = y2 - y1/x2 - x1

1.) 2/5

m = y2 - y1/x2 - x1

m = -1 - (-3)/0 - (-5)

m = -1 + 3/0 + 5

m = 2/5

2.) -7/5

(-2,3) and (3,-4)

m = y2 - y1/x2 - x1

m = -4 - 3/3 - (-2)

m = -4 - 3/3 + 2

m = -7/5

the answer is get a life

I would assume that the angle of f equals 50°... sincesince the triangles are similar that means that the angles are most likely equal to each other. since the big triangle you can do it 90 + 40 which equals 130 then 180, since that is the total degrees in a triangle, minus 130 equals 50 this means 50 ° is the angle of c. keep in mind angle c equals angle f.

Answer:

L < 3s + 5

Step-by-step explanation:

Given that:

Video length of all 3 friend are equal

Let the length of the video made by each friend = s

Length of video of all 3 friends = 3s

Alicia's video segment is less than 5 minutes long

Hence the length L of the full video :

L = (Length of video of all 3 friends + Alicia's video segment)

Since Alicia's < 5

Hence full video length :

L < 3s + 5

Compare the given equation with the general equation of a circle

Given equation: x² + y² - 8x +6y +9 = 0

Equation of a circle: x² + y² + 2gx + 2fy + c = 0

2g= -8; g = -8÷2= -4

2f = 6; f = 6÷2 = 3

c= 9

Solving for radius of the circle...

r =√g² + f² - c

g= -4, g² = ±16

f = 3, f² = 9

Substituting, we have

r = √16 + 9 - 9

r = √25-9

r=√16

r = 4

Therefore, the centre and radius of the circle is 9 and 4 respectively.
