Which graph shows a negative correlation?

Answer:

b = 131

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

b+49 = 180

Subtract 49 from each side

b = 180-49

b =131

Answer:

Angle b is 131°

Step-by-step explanation:

Angles on a straight line add up to 180°

To find b add 49 and b and equate it to 180°

That's

b + 49 = 180

b= 180 - 49

b = 131°

Hello!

The midpoint separates two equal distances,

This means that AB = BC

So lets type of the equation to solve for x:

2x + 7 = 5x -14

Lets add 14 on both sides.

2x + 21 = 5x

Lets subtract 2x on both sides.

21 =3x

Lets divide 3 by both sides

x = 7

AB= 21

2(7) + 7

14 + 7

21

BC = 21

5(7) - 14

35 - 14

21

AC = 42

21 + 21 = 42

I hope this helps, Have a great day!!

Step-by-step explanation: :>

1) Estimate value of the product of 2/3 and 0.55 is, 2/3.

2) The fraction part is, 55 / 100

3) The product of the two numbers is, 11/30

We have to given that,

Estimate the product of 2/3 and 0.55.

And, Convert the decimal 0.55 to a fraction.

And, The product of the two numbers.

Now,

Estimate the product of 2/3 and 0.55,

So, we can round 0.55 to the nearest whole number, which is 1.

Then, multiply 2/3 by 1 to get an estimate of the product.

so, The correct answer is 2/3.

Now, we can convert the decimal 0.55 to a fraction,

= 0.55

= 55/100

= 11/20

Thus,  The correct answer is, 55/100.

And,  the product of 2/3 and 0.55,

= 2/3 x 55/100

= 110/300

= 11/30.

Hence, The correct answer is, 110/300 or 11/30

Answer:

C because elements are form by atoms and when we study about atom we draw atom like circle

so, that's why I think C is correct

Step-by-step explanation:

Option C best shows two elements combining to form a compound.

The term "molecular structure" refers to the structure of a molecule that merely consists of the arrangement of its atoms.

A chemical compound is a material made of several similar molecules that are linked together by chemical bonds and are made up of atoms from various elements.

Chemical compounds cannot be created when two atoms of the same element are bound together since this would need the presence of two distinct elements.

In diagram C it is obtained that atoms are combined to form the compound.

The finest example of two components combining to make a compound is in Option C.

Hence, option C is correct.

After taking the common, the factored form of \(27x^3-64\) is \((3x-4)(9x^2+12x+16)\).

In the given question, we have to find the factored form of \(27x^3-64\).

The following is how we factor the GCF out of a polynomial:

(1) Determine the polynomial's GCF for each term.

(2) Present each term as the GCF and another factor's product.

(3) To factor out the GCF, use the distributive property.

To solve this question we use the formula \((a^3-b^3) = (a-b)(a^2+ab+b^2)\)

We can write \(27x^3-64\) as

\(27x^3-64\) = \((3x)^3-(4)^3\)

\(27x^3-64\) = \((3x-4)((3x)^2+3x\cdot4+(4)^2)\)

\(27x^3-64\) = \((3x-4)(9x^2+12x+16)\)

Hence, the factor form of \(27x^3-64\) is \((3x-4)(9x^2+12x+16)\).

Hey there,

formula: (a + b)(c + d) = ac + ad + bc + bd

Determine if the following functions are equivalent.

f(x) = (x + 8)(x - 3)

f(x) = x*x + x*(-3) + 8*x + 8*(-3)

f(x) = x² -3x + 8x - 24

f(x) = x² + 5x - 24

g(x) = x² + 5x - 24

>> f(x) and g(x) are equivalent ✅

Have a nice day ;)

We are given with two functions f(x) & g(x) respectively , with 3 options and have to choose correct option

Now , here g(x) is already in simplified form , so let's simplify f(x) ;

\({:\implies \quad \sf f(x)=(x+8)(x-3)}\)

We Knows that ;

Using this ;

\({:\implies \quad \sf f(x)=x(x-3)+8(x-3)}\)

\({:\implies \quad \sf f(x)=x^{2}-3x+8x-24}\)

\({:\implies \quad \sf f(x)=x^{2}+5x-24}\)

\({:\implies \quad \bf \therefore \quad \underline{\underline{f(x)=g(x)}}}\)

As f(x) = g(x) . So f(x) & g(x) are equivalent.

Hence , Option 3) f(x) and g(x) are equivalent is correct :D

Probability of two blue chips is

Answer:

\(\sf \dfrac{9}{169}\)

Step-by-step explanation:

The bag has:

⇒ Total number of chips = 6 + 13 + 7 = 26

Probability Formula

\(\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}\)

Probability of choosing a blue chip from the first draw:

Step-by-step explanation:

False. Each triangle in the STL file is defined by the vertices, but not necessarily by the inward pointing surface normal vector. The surface normal vector is often calculated based on the vertex positions.

False. The STL file is a mesh representation of the CAD model, and it does not contain all the information needed to fully reconstruct the original CAD model. It lacks information such as parametric features, assembly relationships, and design intent, making it difficult to recreate the exact original model.

The option "Increasing the heat exchange area for a heat exchanger" is NOT an advantage of using a lattice structure. Lattice structures are known for their lightweight properties, material-saving benefits, and simplified design and manufacturing processes.

However, increasing the heat exchange area for a heat exchanger is not typically associated with lattice structures. Heat exchangers usually rely on other design considerations, such as fin arrays or extended surfaces, to enhance heat transfer efficiency, rather than lattice structures.

Therefore, increasing heat exchange area is not a direct advantage of lattice structures.

c) The probability that a sample size of 36 has a sample mean of less than 19 is of: 0.0228 = 2.28%.

d) It would be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 19, as the z-score has an absolute value of 2.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters of this problem are given as follows:

\(\mu = 20, \sigma = 3, n = 36, s = \frac{3}{\sqrt{36}} = 0.5\)

The probability that a sample size of 36 has a sample mean of less than 19 is the p-value of Z when X = 19, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

Z = (19 - 20)/0.5

Z = -2

The unit tangent vector T and the principal unit normal vector N can be computed for the given vector-valued function r(t) = (sin(t) + 2, cos(t) + 10, 6t). The unit tangent vector T represents the direction of the curve at each point, while the principal unit normal vector N is perpendicular to the tangent vector and points towards the center of curvature.

To find the unit tangent vector T, we differentiate r(t) with respect to t and divide by its magnitude:

r'(t) = (cos(t), -sin(t), 6)

||r'(t)|| = sqrt((cos(t))^2 + (-sin(t))^2 + 6^2) = sqrt(1 + 1 + 36) = sqrt(38)

Therefore, the unit tangent vector T is given by:

T = r'(t) / ||r'(t)|| = (cos(t)/sqrt(38), -sin(t)/sqrt(38), 6/sqrt(38))

To find the principal unit normal vector N, we differentiate T with respect to t and divide by its magnitude:

T'(t) = (-sin(t)/sqrt(38), -cos(t)/sqrt(38), 0)

||T'(t)|| = sqrt((sin(t)/sqrt(38))^2 + (-cos(t)/sqrt(38))^2) = sqrt(1/38 + 1/38) = sqrt(2/38) = sqrt(1/19)

Therefore, the principal unit normal vector N is given by:

N = T'(t) / ||T'(t)|| = (-sin(t)/sqrt(19), -cos(t)/sqrt(19), 0)

In summary, the unit tangent vector T for the given vector-valued function is (cos(t)/sqrt(38), -sin(t)/sqrt(38), 6/sqrt(38)), and the principal unit normal vector N is (-sin(t)/sqrt(19), -cos(t)/sqrt(19), 0). These vectors represent the direction and perpendicular direction to the curve defined by r(t).

Answer: 250 grams/packet = 8 packets.

Step-by-step explanation:

To find the number of 250g packets of biscuits that can be made from 2kg of biscuits, we need to first convert the weight of the biscuits to the same unit of measurement. Since 1 kilogram is equal to 1000 grams, 2kg of biscuits is equal to 2000 grams. Therefore, the number of 250g packets of biscuits that can be made from 2kg of biscuits is 2000 grams / 250 grams/packet = 8 packets.

Step-by-step explanation:

1 kg = 1000 g

as k stands for "kilo" meaning 1000.

250 g fit therefore 4 times into 1 kg.

and then 2×4 = 8 times into 2×1 = 2 kg.

so, there can be 8 250 g packets made from 2 kg.
