Answer 1

The two spheres aren't congruent as B. no, because they have a different radius length

What is congruence?

If two figures have the same shape but different sizes, they are similar. In particular, similar figures' similar lengths are proportional.

In geometry, two shapes or objects are said to be congruent if they have the same dimensions, or if one is the mirror image of the other. Congruent in geometry refers to being the same size and shape. Congruence can be used with figures, angles, and line segments.

Note that the complete information wasn't found but the correct option is B based on searches made.

Answer 2

Answer:

no, because they have a different radius length

Step-by-step explanation:

we can only assume that 12 in and 7 in are the radius or diameter of the 2 spheres.

but it seems clear that whatever these 2 numbers really mean, they are some form of size information about the spheres.

and because they are different, that means that the sizes of the 2 spheres are different.

and therefore, they are not congruent.

congruent means that both compared objects would have to have to same form/shape, angles and overall size.

in other words, they are congruent, if you could place them really "on top of each other" (like holograms), and there would be no part anywhere of one object extruding from the other.

therefore, the first answer option does not make any sense at all. if the spheres would have the same diameter length, they would be congruent.

the third answer option does not make any scientific sense. we don't need to rely on the "looks", when we have precise measurement. and they tell us, that a complete "coverage" of each other of both spheres is not possible.

the fourth answer option is also nonsense, as with different size indicators (like radius or diameter lengths) they simply cannot have the same volume.

If f(x)=5x³-2 and g(x)=x+1, find (f - g)(x).

Answers

Answer:

5x³ - x - 3

Step-by-step explanation:

(f - g)(x) =

f(x) - g(x) =

5x³-2 - (x+1) =  ==> plug in known values

5x³-2 - x - 1 =   ==> simplify

5x³ - x - 2 - 1 = 5x³ - x - 3

What is scatter chart?

Charts that depict the relationship between two variables are known as scatter charts, also known as scatter plots. They are a very effective type of chart because they enable viewers to see relationships or trends right away that are difficult to see in almost any other form.

In order to observe and visually display the relationship between variables, a scatter plot is a common type of chart. Other names for it include scatter gram, scatter graph, and scatter chart.

The conclusion can be drawn from the scatter chart is,

The residuals have an increasing variance as the dependent variable increases.

There is a violation of the homoskedasticity (homogeneity of variance for residuals) assumption.

The given plot is used to check the assumption for homoskedasticity (homogeneity of variances) of data points.

Hence if the homoskedasticity assumption hold, the spread of data points should be along the line and the line should be approximately horizontal.

From the given plot we can see that spread is centered at the middle not equally distributed along the line which is a violation of the homoskedasticity assumption

Hence, the conclusion the residuals have an increasing variance as the dependent variable increases is correct.

What is the probability of a coin landing on heads 4 times in a row?; What is the probability of flipping a coin and it landing heads?; What is the probability that exactly four students toss heads at least 4 times each?; What is the probability of flipping a coin and getting heads both times?

Answers

The probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%, the probability of flipping a coin and it landing heads is 1/2 or, 50%, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%, and the probability of getting heads both times the coin is flipped is 0.25.

There are different situations for us stated as -

(a) What is the probability of a coin landing on heads 4 times in a row?

(b) What is the probability of flipping a coin and it landing heads?

(c) What is the probability that exactly four students toss heads at least 4 times each?

(d)What is the probability of flipping a coin and getting heads both times?

We have to find out the probability of the given situations happening.

(a) It is known to us that a coin is flipped.

We have to determine the probability of this coin landing on heads 4 times in a row.

In order to get 4 heads in a row, the coin should be flipped 4 times.

For n (say) number of heads, the value of n = 0, 1, 2, 3, 4

Total number of possible outcomes = 16

It can be concluded that there is only one possible outcome that will result in the coin landing on 4 heads where each flip ends up as a head.

So, the probability = 1/16

Thus, the probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%.

(b) It is known to us that a coin is flipped.

We have to find out the probability of this flipped coin landing on heads.

When a coin is flipped in the air, there is always 50% chance of the coin landing on heads and a 50% chance of the coin landing on tails.

So, the probability = 1/2

Thus, the probability of flipping a coin and it landing heads is 1/2 or, 50%.

(c) It is known to us that exactly four students toss coins.

We have to determine the probability that exactly four students toss heads at least 4 times each.

As mentioned in the previous part of the question, there is always 50% chance of the coin landing on heads.

So, the probability of getting heads when the coin is flipped first = 1/2

=> the probability of getting two heads in a row = 1/2 * 1/2 = 1/4

=> the probability of getting three heads in a row = 1/2 * 1/4 = 1/8

=> the probability of getting four heads in a row = 1/2 * 1/8 = 1/16

Thus, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%.

(d) It is known to us that a coin is flipped.

We have to find out the probability of getting heads both times.

Since, there is always 50% chance of the coin landing on heads. So, the probability of getting heads both times = 0.5 * 0.5 = 0.25

Thus, the probability of getting heads both times the coin is flipped is 0.25.

Therefore, the probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%, the probability of flipping a coin and it landing heads is 1/2 or, 50%, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%, and the probability of getting heads both times the coin is flipped is 0.25.

What is the solution of the system of equations? y= x + 2, y = 3x

Answers

Answer:

[tex]x = 1 , y = 3[/tex]

Step-by-step explanation:

Note that each equation is equal to y. Set the equations equal to each other:

[tex]y = x + 2\\y = 3x\\\\x + 2 = y = 3x\\x + 2 = 3x[/tex]

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x from both sides of the equation:

[tex]x + 2 = 3x\\x (-x) + 2 = 3x (-x)\\2 = 3x - x\\2 = 2x[/tex]

Next, divide 2 from both sides of the equation:

[tex]2x = 2\\\frac{2x}{2} = \frac{2}{2} \\x = \frac{2}{2} = 1\\x = 1[/tex]

Next, plug in 1 for x in one of the given equations:

[tex]y = x + 2\\\\x = 1 \\[/tex](given).

[tex]y = (1) + 2\\y = 3[/tex]

[tex]x = 1 , y = 3[/tex] is your answer.

Answer is (1 , 3)

Step by step

Equation A y= x + 2
Equation B) y = 3x

Substitute value of y (3x) from Equation B into Equation A

3x = x + 2

Subtract x from both sides

3x - x = x - x + 2

Combine like terms

2x = 2

Divide both sides by 2 to solve for x

2/2 x = 2/2

x = 1

Now solve for y, substitute value of x into equation A

y = 1 + 2

y = 3

Now check your work, sub in x and y value into Equation A)

3 = 1 + 2

3 = 3

They equal so the solution is correct!

g is the centroid of triangle abc.what is the value of x? what is the length of segment dg? unitswhat is the length of segment ag? unitswhat is the length of segment ad? units

Answers

g is the centroid of triangle abc, the value of x is 2/3.

The length of segment DG is (2/3) * (length of AB) ,The length of segment AG is (1/3) * (length of AB),The length of segment AD is (1/3) * (length of AB).

The centroid of a triangle is the point at which the three medians of the triangle intersect each other. In other words, it is the point of intersection of the three lines which each divide the opposite side of the triangle into two equal parts.

Let us consider a triangle ABC with vertices A (a1, b1), B (a2, b2), and C (a3, b3). The x coordinate of the centroid G (x, y) is given by:

x = (a1 + a2 + a3) / 3

The y coordinate of the centroid G (x, y) is given similarly as x

In your question, the x coordinate of the centroid G is given as x = 2/3. This means that the x coordinate of G is 2/3 of the way between A and B.

Therefore, the length of segment DG is (2/3) * (length of AB).

Answers

The answer is A & C

To determine if a set of ordered pairs represents a function, you can check if each input (x value) is associated with only one output (y value).

In set A, input 4 is paired with output 1 and input 8 is paired with output 2. These two inputs are paired with only one output, so the set A can represent a function.

In set B, input -2 is paired with two different outputs.

-1 and 5. This means that -2 has multiple exits, so set B does not represent a function. In set C, input 7 is paired with output 4 and input 8 is paired with output 3. The set C can represent a function because these two inputs are paired with only one output.

The marked price of an article is Rs. 8000. After allowing a certain percent of discount with 13% Value Added Tax (VAT) levied, the articles is sold at Rs 7684. Find the difference between discount amount and VAT amount.​

Answers

Answer:

$1200.00

Step-by-step explanation:

Let x = the discounted priced

x + .13x = 7684  Combine like terms.

1.13x = 7684  Divide both sides by 1.13

[tex]\frac{1.13x}{1.13}[/tex] = [tex]\frac{7684}{1.13}[/tex]

x = 6800

$6800 is the cost of the discounted article before tax.

8000 - 6800 = 1200

What is equation?

equation is another name for a declaration of equality between two expressions that contain variables and/or numbers. From solving equations is essentially solving problems, solving equations has been the central goal of mathematics since its inception. There are many distinct types of equations that range in complexity, from simple algebraic equations that merely need addition or multiplication through differential equations, exponential equations that use exponential expressions, and integral equations.

we know that,

the point p on the line y=5x that is closest to the point (52,0) will be on the line perpendicular to the line y=5x and go through the point (52,0)

step 1

the slope m perpendicular to the line y=5x is

m1=5

if two lines are perpendicular

m1*m2=-1

m2=-1/5

step 2

with m=-1/5 and the point (78,0) find the equation of a line

y-y1=m*(x-x1)-----> y-0=(-1/5)*(x-52)----> y=-0.20x+10.4

step 3

resolve the equation systems

y=5x

y=-0.20x+10.4

Thus substituting the values in y of x

=> 5x=-0.20x+10.4

=> 5.20x=10.4

=> x=2

Therefore the point comes out to be

x=2

y=10

The least distance between P(2,10) &(52,0)= 50.99 units

Therefore the point P in the coordinate plane comes out to be (2,10)

and the distance between the points is 50.99 units
