compare the price per dozen eggs at the local grocery store and at the supermarket Edward bought 8 dozen eggs in the supermarket how much did he save by buying eggs at the supermarket instead of the local store​

No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.

b )It is represented by - 5 yards.

c) It is represented by - 8 yards.

d) Addition sentence will be ; 8 + 5 = 13

e) The answer will be 13.

It is given that a football team loses 5 yards on one play and then loses 8 yards on the next play.

We have to answer the given questions based on the provided data.

What will be the value if 2 times of 10 is added to 10 ?

The value will be ; 20 + 10 = 30.

As per the question ,

A football team loses 5 yards on 1st game and 8 yards on 2nd game.

Let's give answer to the question ;

a)

Total yards the team lost in two plays

= 8 +5

= 13

b) As the team is loosing 1st play , we can consider it as a negative value.

  So ,

  It can be represented by x = - 5 yards.

c) As the team is loosing in 2nd play , we can consider it as a negative value.

  So ,

  It can be represented by x = - 8 yards.

d) The expression for addition can be written as ;

  8 + 5 = 13

e) The answer to the question will be equal to 13 yards.

Thus , we can conclude that ;

a ) they loose 13 yards in two plays.

b )It is represented by - 5 yards.

c) It is represented by - 8 yards.

d) Addition sentence will be ; 8 + 5 = 13

e) The answer will be 13.

Answer:

16

Step-by-step explanation:

192/12=16

hope this helps :3

if it did pls mark brainliest

Answer:16

192/12 equals 16

Answer:

x= 12

Step-by-step explanation:

(9x -4)° +(5x +16)° = 180° (int. ∠s, L//m)

9x -4 +5x +16= 180

14x +12= 180 (simplify)

14x= 180 -12 (-12 on both sides)

14x= 168

x= 168 ÷14 (÷14 on both sides)

x= 12

Answer:

The correct option is b

Step-by-step explanation:

The correct option  is  matched pair design the reason for this is because in the experiment individual(elements)  are group into pairs based on a characteristics that they have in common (in this question the characteristics being a twin) and then within each group the subject a placed on different treatment , in the case of this question each twin in each group are placed on different treatment (i.e one is given the mouthwash while the other is not ).

This process which I have explained is how a matched pair design is carried out

Answer:

length/distance = 10 units

Step-by-step explanation:

Use the distance formula for both points / length / magnitude, d = √((x2-x1)^2+(y2-y1)^2).

Given endpoints (-3,8) [(x1,y1)], and (7,8) [(x2,y2)], plug in the corresponding y, and x values of both coordinates, and simplify.

√((8-8)^2+(7-(-3))^2) = √(0^2+10^2) = √100 = 10

*This may be in units if the unit used is unspecified.*

_______________________________

Also since the y values of both coordinates are the same, you can just subtract the x values in the coordinates, and take the absolute value since distance/length cannot be negative.

Step-by-step explanation:

[tex]|AB | = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} [/tex]

[tex] = \sqrt{( - 3 - 7)^{2} + (8 - 8)^{2}} \\ = \sqrt{100 + 0} = 10[/tex]

Answer:  Choice A

y = (-2/3)x + 12

================================================

Work Shown:

We will only focus on the two points that are on the regression line.

Those two points are (3,10) and (12,4)

Let (x1,y1) = (3,10) and (x2,y2) = (12,4)

Find the slope of the line through (x1,y1) = (3,10) and (x2,y2) = (12,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 10)/(12 - 3)

m = -6/9

m = -2/3

Plug m = -2/3 and (x1,y1) = (3,10) into the point slope formula

Solve for y.

y - y1 = m(x - x1)

y - 10 = (-2/3)(x - 3)

y - 10 = (-2/3)x + (-2/3)(-3) ... distribute

y - 10 = (-2/3)x + 2

y - 10 + 10 = (-2/3)x + 2 + 10 .... add 10 to both sides

y = (-2/3)x + 12

This matches up with what the graph shows because the regression line intersects 12 on the y axis, so the y intercept is 12.

y = (-2/3)x + 12 is in the form y = mx+b with m = -2/3 as the slope and b = 12 as the y intercept.

Answer:

If you're talking about solutions in general (real and imaginary solutions), there is 2, because the fundamental theorem of algebra says that the number of roots of any polynomial is the degree if it's highest power, which is 2.

If you're talking about only real solutions, there is 0. To show that, we can take the discriminant (b^2-4ac) part of the quadratic equation, and plug in the know values. We then get:

(-3)^2-4*2*12

=9-96

=-87

Remember, the discriminant will be taken the square root. Since this is negative, the answer will be imaginary. Therefore, there is no real solution.

Step-by-step explanation:

Answer:

97

Step-by-step explanation:

Given that:

Low = 43bpm

High = 115 bpm

Error = 3

α = 90%

To find the range estimate :

Standard destviation = (high - low) / 4

Standard deviation = (115 - 43) / 4

Standard deviation = 72/4 = 18

The sample size,(n) :

n = [(Zα/2 * sd)/E] ²

2 - tail = (Zα/2) = 1.645

[(Zα/2 * sd)/E] ² = [(1.645 * 18) / 3]² = (29.61/3)²

= 97.41

Sample size = 97

Equation at the end of step 1

 (5p2 -  2p) -  3

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  5p2-2p-3  

The first term is,  5p2  its coefficient is  5 .

The middle term is,  -2p  its coefficient is  -2 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   5 • -3 = -15  

Step-2 : Find two factors of  -15  whose sum equals the coefficient of the middle term, which is   -2 .

     -15    +    1    =    -14  

     -5    +    3    =    -2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -5  and  3  

                    5p2 - 5p + 3p - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   5p • (p-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (p-1)

Step-5 : Add up the four terms of step 4 :

                   (5p+3)  •  (p-1)

            Which is the desired factorization
