The value of the expression |-10+6|-|3²-5| = 0

The expression given is |-10+6|-|3²-5|.

This contains absolute value which needs to be evaluated.

We will go through the definition of absolute value.

Absolute value for x = x, when x is a positive integer.

i.e., |x| = x, when x >0

Absolute value of (-x) = x, when -x is a negative integer.

So absolute value always gives the positive value of the number inside it.

Now |-10+6|-|3²-5| = |-4| - |9-5|

                              = 4 - |4|    [Since |-4| = 4]

                              = 4 - 4      [Since |4| = 4]

                              = 0.

So the value of the expression |-10+6|-|3²-5| = 0

The length is 780 feet and the width is 430 feet.

Distance is measured in length.

The dimension of distance is a property of length in the International System of Quantities.

Let the length be x

Width = x - 350

Perimeter = 2260 feet

Now : 2(x + x +350) = 2260

or, 2 x + 700 = 2260

or, 2x = 1560

or, x = 780 feet

So length is 780 feet

Width = 780 -350 = 430 feet

Therefore the length is 780 feet and the width is 430 feet.

Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

In null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.

In this problem, we consider that:

p₁ is the proportion in 2014.

p₂  is the proportion is 2017.

H₀=p₂-p₁

By alternative hypothesis,

H₁=p₂-p₁≠0,

we test if there has been an increase

The proportions and standard errors are given by:

p₁=0.97, s₁=√0.97(0.803)/61=0.0509

p₂=0.385, s₁=√0.385(0.615)/52=0.0675

Hence, the distribution has mean and standard error given by:

p=p₂-p₁=0.0675-0.0509

s=√s₁²+s₂²=0.0845

Test static z=p bar-p/s

at p = 0 is the value tested at the null hypothesis,

z=0.0166/0.0845

z=0.2

By a right-tailed test,  we are testing is  the proportion is greater than a value, with a significance level of 0.05, the critical value is of

z=1.645

0.2<1.645 there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

Answer:

How about:

0, 1, 2, 3, 4..............

lol jk here:

0, 66, 132, 198, 264

Step-by-step explanation:

Guess what it is! ;p

Step-by-step explanation:

it is a bit difficult to read the handwriting (and even the printed original texts) in this diffuse picture.

let's go through the 3 problems as I could decipher them.

1)

from what I can see you made a calculation mistake for y.

but you were right with your approaches.

12x - 8 = 15x - 23

15 = 3x

x = 5

therefore,

12x - 8 = 12×5 - 8 = 60 - 8 = 52°

and the large angle up there is

52 + 70 = 122°

and now

6y + 96 = (12x - 8) + 70 = 122

6y = 26

y = 26/6 = 13/3

by the way, x and y are not angles (and degrees). they are just factors in the expressions to calculate some angles.

12, 15 and 6 are not ° either. all are calculation factors or terms, that then together define the ° of angles.

2)

you made a mistake with the identification of what angles the linear pair is.

3x = 5x - 20

20 = 2x

x = 10 (again, not °, just a number)

3x = 3×10 = 30° (this is then an angle)

= 5x - 20

for y we could then use 2 different approaches

a) your linear pair approach.

4y is one angle, true, but the other is (2y + 3x) !

so,

4y + 2y + 30 = 180

6y = 150

y = 25 (again, not °, just a number)

2y = 50°

4y = 100°

3)

I hope you are right with (11x + 19) and (12y - 24). I would have read this in the picture as (11x + 18). and it could be (12y + 24).

assuming you are right :

11x + 19 = 7x + 47

4x = 28

x = 7 (again, not °, just a number)

11x + 19 = 7x + 47 = 96°

7z + 17 = 87

7z = 70

z = 10 (again, not °, just a number)

and yes, for y we are using the linear pair again. the two combining angles are (12y - 24) and (11x + 19).

(12y - 24) + (11x + 19) = 12y - 24 + 96 = 180

12y + 72 = 180

12y = 108

y = 9 (again, not °, just a number)

12y - 24 = 12×9 - 24 = 108 - 24 = 84°

For given angle of elevation equals to 66 degree and distance to kite is 303feet and hand is 4 feet above the ground then kite is 280.8feet high.

As given,

Shown in diagram attached,

Angle of elevation ∠AEB=66°

Distance to the kite AE=303 feet

Hand above the ground DE=4feet

DE=BC

BC=4feet

Let 'h' be height of AB

Height of the kite=(h +4)feet

In ΔABE,

sin66°=h/303

⇒h=sin66° ×303

     =0.9135 ×303

      =276.7905

      ≈276.8 feet

Height of kite=(h +4) feet

                             =276.8 +4

                             =280.8 feet

Therefore, for given angle of elevation equals to 66 degree and distance to kite is 303feet and hand is 4 feet above the ground then kite is 280.8feet high.

Aryon is left with $9.25 of money after he has paid for his lunch.

According to the question,

We have the following details:

Total amount Aryon has = $20

The cost of 1 coke = $1.50

So, the cost of 2 cokes = $(2*1.50)

The cost of 2 cokes = $3

The cost of a sandwich = $5.50

The cost of a bag of chips = $2.25

So, the total cost of all the materials = the cost of 2 cokes + the cost of a sandwich + the cost of a bag of chips

The total cost of all materials = $(3+5.50+2.25)

The total cost of all materials = $10.75

Now, the money Aryon has = Total money he has - the total cost of all materials

The money Aryon is left with = $(20-10.75)

The money Aryon is left with = $9.25

Hence, the money Aryon is left with is $9.25.

In the year 2006, the number of free throws is 100, number of 2 point field goals 128 and the number of 3 point field goals 90.

Let x = number of free throws

y = number of 2 point field goals

z =  number of 3 point field goals

However given that Rebecca has a total of 806 points,

Thus x + 2y + 3z = 806 ---------- equation 1

Number of 2 point field goals that Rebecca made was 52 less than double the number of​ three-point field goals she made ;

thus y = 2z - 52 ---------------- equation 2

Number of 3 point field goals that Rebecca made was 28 less than the number of​ two-point field goals she made ;

thus x = y - 28 ------------------ equation 3

Thus on solving these three above mentioned equations :

we get x = 2z - 52 -28 [ substituting values in eq 3 from eq 2]

x = 2z - 80 ------------- equation 5

So equation 1 becomes ; 2z - 80 + 2y + 3z = 806

5z + 2y = 886 -------------- equation 4

Thus on solving equation 4 and 2 we get

2 X equation 2 = 4z - 2y = 104

                            5z + 2y = 886

                      = 11 z = 990

thus z = 90 and so y = 4 × 90 - 104 = 2y

y= 360 - 104 / 2

= 256/2 = 128

thus y = 128 .

And x= 2z -80 from equation 5 ; x = 180 - 80 = 100 .

Answer:

530 x

Step-by-step explanation:

By solving the system of equations, we can see that the solutions are:

(A, B) = (4, 9)

(C, D) = (1, -6).

Here we have the following system of equations:

x^2 - y = 7

y - 5x = -11

If we isolate the variable y in both equations, we get:

y = x^2 - 7

y = -11 + 5x

Now we can equate these two to get:

x^2 - 7 = -11 + 5x

now we have a quadratic equation, this can be rewritten as:

x^2 - 7 + 11 - 5x = 0

x^2 - 5x + 4 = 0

Using the quadratic formula, we will see that the solutions are:

[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*(4)} }{2*1}[/tex]

Solving that we get:

[tex]x = \frac{5 \pm \sqrt{(9} }{2} \\\\x = \frac{5 \pm 3}{2}[/tex]

So the two solutions for x are:

x = (5 + 3)/2 = 4

x = (5 - 3)/2 = 1

Evaluating the second equation in these x-values we get:

y = -11 + 5*4 = -11 + 20 = 9

y = -11 + 5*1 = -6

Then we have the coordinate pairs: (4, 9) (on the first quadrant) and (1, -6) on the fourth quadrant.

Inequality is 32.50x + $10.50 ≤ $160 and 4 people can go to the amusement park.

inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.

Given that,

$160 = Amount of money they have

$10.50 = Parking Cost

$32.50 = Cost of tickets per person

Because they only have $160, they can't spend more than that amount.

Therefore, the inequality would be the ticket cost per person, times the amount of people being payed for (x) plus the parking cost is less than or equal to the amount of money they have to spend. Hence the inequality:

32.50x + $10.50 ≤ $160

Solve the equation

$160 - $10.50 = $149.50 (149.50 is how much is left for tickets after subtracting the parking cost)

$32.50 x 4 = $130 (4 tickets can be bought for the price of $32.50)

$149.50 - $130 = $19.50 (19.50 isn't enough for another person)
