Look at the following model.What is incorrect in the model?

(-1,3)

you plug -1 into the equation y=2x+5 for x since that is what x is equal to and then solve it so y= -3 then your coordinates would be (1,-3)

Step-by-step explanation:

Cuz sides of square are same, we just find hypotenusa side of triangle (use Phytagoras Theorem) :

c² = a² + b²

c² = 2² + 4²

c² = 4 + 16

c² = 20

c = √20

Side of square is √20 units.

The area of square :

A = s²

= √20²

= √20 × √20

= 20 units²

So, the area of square is 20 units²

An infinite sum of all the all the cross-sections of a 3D figure parallel to the base equals the volume of that 3D figure.

Answer:

6

Step-by-step explanation:

1. Combine like terms (x)

Subtract 2 from one side to move it to the other side. *What you do to one side, you must do to the other.

You now have: 5x(-2x)+ 4= 22

Subtract 2 from 5= 3x

You now have 3x+ 4 = 22

*You can’t add 4 to 3x because they are different terms (can’t add whole numbers with an x value)

Subtract 4 to move it to the other side;

3x= 22-4

22-4 = 18

3x=18

Divide by 3 to remove 3 from one side

X= 6 (because 18/3= 6

Answer: x = 6

Explanation: This problem can be done either of two ways by putting the variables together on the left and the numbers together on the right or vice versa.

If we put our variables together on the left and our numbers together on the right, we would start by subtracting

2x from both sides to get 3x + 4 = 22.

Next, we subtract 4 from both sides to get 3x = 18.

Finally, we divide both sides by 3 to get x = 6.

Note that we can check our answer by plugging 6 back in

for both of the x's in the original equation.

So go ahead and check the answer and see if it works.

-f +2+4f = 8-3f

3f+2 = 8-3f

6f = 6

f = 1

Answer:

f = 1

Step-by-step explanation:

Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other.

Add 3f and subtract 2 from both sides:

-f + 2 (-2) + 4f (+3f) = 8 (-2) - 3f (+3f)

-f + 4f + 3f = 8 - 2

Simplify:

(-f + 7f) = 6

7f - f = 6

6f = 6

Isolate the variable, f. Divide 6 from both sides:

(6f)/6 = (6)/6

f = 6/6

f = 1

1 is your answer for f.

That's the Riemann Zeta function. Here s is a complex number.  If you can prove that all the non-trivial zeros of ζ(s) (which includes its analytic continuation to the entire complex plane) are on the line Re(s) = -1/2 then you will become a famous mathematician.  You didn't even ask a question; not a very auspicious start, but don't give up.

If we restrict s to the reals, as Euler first did, we can prove there are an infinity of primes.  Ever since the Zeta function has been closely related to the prime numbers.

One fun fact is ζ(-1) = -1/12, which has spawned lots of bad math claiming the sum of the natural numbers is -1/12,

[tex]-\dfrac{1}{12} = \zeta(-1) = \dfrac{1}{1^{-1}} + \dfrac{1}{2^{-1}} + \dfrac{1}{3^{-1}} + ... = 1 + 2 + 3 + 4 + ...[/tex]

Answer:

83 liters

Step-by-step explanation:

If we call the amount of liters of the 8% iodine solution by x and the amount of liters of the 44% iodine solution by y, we can write the following equations:

x + y = 200

x*0.08 + y*0.44 = 200*0.29

From the first equation, we have that y = 200 - x

Using this value of y in the second equation, we have that:

0.08x + (200 - x)*0.44 = 58

0.08x + 88 - 0.44x = 58

0.36x = 30

x = 30/0.36 = 83.3333 liters

Rounding to nearest liter, we have x = 83 liters

1x + 8 = 10 + 0.5x

1x - 0.5x = .5x

.5x + 8 = 10

10 - 8 = 2

2/.5 = 4

plzz mark me brainliest

Answer:

Let's say:

AM = current amount of money = 3000

APR = interest rate  = 2.25

n = number of compounding periods

t = 5 years

Final amount of money:

FAM = AM x [1 + 2.25/n]^(n x 5) = 3000 x [1 + 2.25/n]^(n x 5)

Annual Compounding: FAM = 3000 x (1 + (2.25% / 1))^(1 x 5) = 3353.03

Quarterly Compounding: FAM = 3000 x (1 + (2.25% / 4))^(4 x 5) = 3356.16

Monthly Compounding: FAM = 3000 x (1 + (2.25% / 12))^(12 x 5) = 3356.86

Continuous Compounding: FAM = 3000 x 2.7183^(2.25% x 5) = 3357.22

=>Continuous Compounding gives largest benefit.

=> Option C is correct

What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x + 12?

A. (–∞, –3]   (B) [–3, ∞)  (C)(–∞, 15]  (D)[15, ∞)

Answer:

(D)[15, ∞)

Step-by-step explanation:

We want to determine what interval of x includes all possible values of x in: [tex]-3(6 - 2x) \geq 4x + 12[/tex]

First, we open the bracket on the Left hand side

[tex]-18+6x \geq 4x + 12[/tex]

Next, we collect terms with x on the Left hand side and constants on the right hand side.

[tex]6x-4x \geq 12+18\\2x\geq 30\\$Divide both sides by 2\\x \geq 15[/tex]

Therefore, the interval of x which includes all possible values of x is [15, ∞).

Option D is the correct option.

Let's put all of these into percent form.

P(Guilty) = 0.25 = 25%

P(Innocent) = 55%

P(Retrial) = 1/5 = 0.2 = 20%

Next, we need to order them from least to most likely. The least likely event to occur would be the smallest percent, then the next smallest, etc.

Order: Retrial, Guilty, Innocent

Hope this helps! :)

Answer:

retrial, guilty, innocent

Step-by-step explanation:

We need to first convert these into the same kind of format, whether it's all decimals, all fractions, or all percentages. Let's just do decimals.

The guilty is already a decimal: 0.25.

The innocent is a percent. Remember that % simply means "out of 100", so 55% is 55/100. When we divide by 100, we move the decimal point two places to the left, so 55/100 = 0.55.

The retrial is a fraction. Just try to remember that 1/5 always equals 0.2.

The least likely event will be the smallest decimal, which is 0.2. The most likely event is the largest decimal, which is 0.55. So, the order is:

retrial, guilty, innocent

Both distributions are nearly symmetric. And the correct answer is A.

The distribution of values in a field is described by a statistical distribution, often known as a probability distribution. In other words, the statistical distribution identifies the typical and unusual values. The bell-shaped normal distribution is one of many varieties of statistical distributions.

A histogram is a graphical illustration of information in bars of diverse heights.

A histogram displays the shape and spread of continuous sample data.

Answer:

(-b) (4a-b)

Step-by-step explanation:

(2a – b)^2- 4a^2

Let m = 2a-b

m^2 - (2a)^2

We know this is the difference of squares

x^2 - y^2 = (x-y)(x+y)

(m-2a) (m+2a)

Replace m with 2a -b

(2a -b-2a) (2a-b+2a)

Simplify

(-b) (4a-b)

Answer:

(4a - b)(-b)

Step-by-step explanation:

If we let x = 2a - b and y = 2a, our expression now looks like

[tex]x^2-y^2[/tex]

This kind of a expression is a common pattern in algebra called a difference of squares, and it can be factored like this (for a visual proof, see the attached image, courtesy of Great Maths Teaching Ideas):

[tex]x^2-y^2=(x+y)(x-y)[/tex]

Replacing x and y with 2a -b and 2a, our expression now becomes

[tex][(2a-b)+2a][(2a-b)-2a]\\=(2a-b+2a)(2a-b-2a)\\=(4a-b)(-b)[/tex]

So in factored form,

[tex](2a-b)^2-4a^2=(4a-b)(-b)[/tex]

Answer:

f(3) =16

Step-by-step explanation:

f(x) = 3x + 7

Let x= 3

f(3) = 3*3 +7

     = 9+7

      = 16

Answer: 16

Step-by-step explanation: f(x) = 3x + 7 means that if we put an x into our function, a 3x + 7 comes out.

So if we want to find f(3), we're putting a 3 into our function which means that a 3(3) + 7 comes out which simplifies to 9 + 7 or 16.

So f(3) = 16 or the value of the function at 3 equals 16.

The required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total marbles [sample space] = 100
Total favorable outcome = 40 = 40%
Now,
Picking another blues marble,
Total marble becomes 99 and the total favorable outcome becomes 39,
Probability of picking marble in two consecutive drawn,
= 40/100 × 39 / 99
= 0.158
= 15.8%

Thus, the required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.
