When one column adds up to more than 10, you regroup 10 Ones into 1 Tens

Regrouping is done by making groups of tens during operations like subtraction and addition. Regrouping means rearranging numbers into groups by place value to make it easier to carry out operations. This process is called regrouping because you're rearranging numbers into place value to carry out the process.

To regroup means to rearrange groups in place value to carry out an operation.

When one column adds up to more than 10, you regroup 10 Ones into 1 Tens. Don't put the carry over in the answer area at the bottom of the column. Write it at the top. After we carry the 1, we add all the Tens place digits, including the carry.

Step-by-step explanation:

The correct option is the 1st one. "The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3."

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

Given that, Two students created paintings for their art class. The canvas size used for each is shown.

4 ft

6 ft

2 ft

3 ft

So the ratio of  width and length of 1st painting = 4:6 = 2:3

And, the ratio of  width and length of 2nd painting = 2:3

Hence, we can conclude that, The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.

For the maximum area, the wire should be bent in the form of a circle and for the minimum area, the wire should bend into an equilateral triangle.

What is the area of any geometrical shape?

The area of a shape is the “space enclosed within the perimeter or within the boundary” of the given shape. We calculate the area for different shapes using math formulas.

Given that a piece of wire 10m long is cut into two pieces so now we have two wires with lengths of 5m and 5m.

One wire is bent into an equilateral so the perimeter of that triangle would be 3 m.

Perimeter = 3 m

3*side = 3 m

side = 1 m

Now the area of the equilateral triangle = [tex]A=\frac{\sqrt{3}}{4} $ $ \times $ (side)^2$[/tex]

                                                                   A = 0.4330 m² -----(I)

Now the circumference of the circle = 5 m

                     2π×r = 5

                      r = 5/2π

                      r = 0.7957 m.

Now the area of the circle = π×r²

                                           = 3.14 × (0.7957)²

                                           = 1.988 m² --------(II)

From (I) and (II), we can say that

Area of the equilateral triangle < Area of the circle

Hence, for the maximum area, the wire should be bent in the form of a circle and for the minimum area, the wire should bend into an equilateral triangle.

The amount of yellow balls in the jar is 1000, with the probability.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A value between 0 and 1 represents the likelihood of an event, with 0 basically denoting impossibility and 1 generally indicating certainty.

in a jar there are 600 red balls and 400 green balls and an unknown amount of yellow balls.

probability is 1/5 for green ball.

The Total number of balls 1000+x

So given the probability of green is 400/1000+x = 1/5

1000+x = 5*400 = 2000

x = 2000-1000=1000

a. Mixed cost - the cost per unit decreases with increase in units sold.

b. Variable cost - the expense increases with increase in units sold

c. Fixed cost - expense is constant with increase in units sold.

d. Fixed cost - cost is constant with increase in units sold.

e. Variable cost - cost increases with increase in units sold

f. Variable cost - cost increases with increase in units sold

g. Mixed cost- depreciation cost decreases with increase in units sold.

h. Fixed cost - cost is constant with increase in units sold.

i. Variable cost - cost increases with increase in units sold

j. Fixed cost- cost is constant with increase in units sold.

According to the given question;

Mixed costs: That has a high initial cost generally because they contain some fixed components and change in proportion because they contain some variable components.

Fixed costs: Costs that are consistent or constant are known as fixed costs.

Variable costs: These alter as the quantity of units changes.

(a) The price is fixed. This is because even while the price per unit fluctuates, the overall price does not. For instance, the total cost for 20 units is $720 ($36 x 20 units), and the total cost for 100 units is $720 ($7.2 x 100 units).

(b) The overall cost of the phone is mixed. On the basis of unit cost fluctuations, it may be claimed that the first 20 units have a fixed component and that subsequent 20 units have an equal distribution of fixed and variable costs.

(c) The price is vary. Supply costs are fixed regardless of quantity changes, and variable cost per unit is also fixed regardless of quantity changes that affect changes in the aggregate but not in the individual.

(d) The fact that the overall insurance cost remains constant as the quantity changes suggests that it is a fixed cost.

(e) Total salary expenses are mixed costs since they have a higher initial cost due to the inclusion of some fixed costs and ratio changes as a result of the addition of variable costs.

(f) Variable expenses, which rise in line with an increase in quantity, make up the entire cost of items sold.

(g) Depreciation is a fixed cost because, despite the fact that unit cost reduces as quantity increases, total cost remains constant.

(h) The total rent expense is constant despite changes in quantity, indicating that it is a fixed expense.

(i) The price of shopping bags is variable since the price and total fluctuate when the amount changes.

(j) Since individual unit expenses are constant per unit, the cost per unit of goods sold is variable.

The mean number of visitors to the museum is much greater than the median number of visitors.

What is median?

The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simples to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the center of a sequence to determine its value.

Option (a) is unquestionably incorrect since the probability that there will be 450 to 500 investors is extremely low (0.05), and investors are not, in fact, the visitors with the highest possibility of visiting the museum.

We will take the midpoint value of the class intervals as the given distribution is expressed as class intervals in order to simplify the data in this distribution.

Mean = 306

Since the mean(306) is coming out to be greater than the median (300)

Therefore the correct option is,

(C) the mean number of visitors to the museum is much greater than the median number of visitors.

Hence the mean number of visitors to the museum is much greater than the median number of visitors.

b)E(X/Y = 2) = 2

c) E(Y²) = 1.2

d) σᵧ= 0.7483

e) E(3Y) = 2.4

We are given that X, Y denotes the number of students and number of questions respectively.

P(X,Y) denote the joint probability mass function for X and Y. Also provide,

P(0,0)=0.04, P(1,0)=0.16, P(1,1)=0.1, P(2,0)=0.2, P(2,1)=0.3, P(2,2)=0.2.

Therefore the required quantities here are computed as:

P(X = 0) = 0.04

P(X = 1) = 0.26

P(X = 2) = 0.7

a) E(X³) = 0 + 1×0.26 + 23×0.7

= 5.86 is the required value here.

b) Now given Y = 2, the conditional Probability density function for X here is obtained as:

P(X = 2 | Y = 2) = 1

Therefore, E(X | Y = 2) = 2 here.

c) For Y, we have here:

P(Y = 0) = 0.4

P(Y = 1) = 0.4

P(Y = 2) = 0.2

Therefore,

E(Y²) = 0.4×1 + 22×0.2

= 1.2 is the required value here.

d) The standard deviation of Y here is computed as:

E(Y) = 1×0.4 + 2×0.2 = 0.8

S.D(Y) = sqrt( E(Y²) - [E(Y)]²) = sqrt( 1.2 - 0.82 )

To learn how to draw a square with a compass, follow the steps below:

A square is a regular quadrilateral with four equal sides and four equal angles in Euclidean geometry. It is alternatively defined as a rectangle with two equal-length adjacent sides.

1. We begin with a provided line segment AB>, which will become one of the square's sides.

2. Move the AB line to the right.

3. Place the compasses on B and any suitable width. Draw an arc on each side of B, resulting in the points F and G.

4. Draw an arc above the point B with the compasses on G and any convenient width.

5. Place the compasses on F and draw an arc above B, crossing the preceding arc, and forming point H without changing the width of the compasses.

6. Make a line from B to H. Because this line is perpendicular to AB, the angle ABH is a right angle (90°); this will form the square's second side.

7.Place the compasses on A and adjust the width to AB. This width will remain constant as we design the other three sides of the square.

8. Draw an arc from point A to point B.

9. Move the compasses to point B without changing the width. Draw an arc over BH to create point C, the square's vertex.

10. Move the compasses to C without affecting the width. Draw an arc to the left of C across the existing arc, forming point D - the square's vertex.

11. Draw the CD and AD lines.

The equation of the tangent line to the curve at the point is 2y = x + 1.

Here we have to find the equation of the tangent line to the curve at the point.

The given data:

x = cosФ + sin 2Ф

y = sinФ + cos 2Ф

Now let us differentiate it, as we have to find the tangent of the curve.

dx/ dФ = -sinФ + 2 cos 2Ф

dy/ dФ = cosФ - 2sin2Ф

So we get dx/dy as:

dy/ dx = cosФ - 2 sin 2Ф / -sinФ + 2cos 2Ф

Now as it is given that Ф = 0. So putting Ф as 0 we have:

dy/ dx = cos0° - 2 sin 0° / -sin0° + 2 cos 0°

          = 1 / 2

Now we get the value of x and y by putting Ф as 0°

x = cos0° + sin 0°

 = 1

y = sin 0° + cos 0°

  = 1

So we get the equation:

y - 1 = 1/2( x-1)

2(y - 1 ) = x - 1

2y - 2 = x -1

2y = x + 1

Therefore the equation is 2y = x + 1.

m∠QRO = 46°

Step-by-step explanation:

In the question, we are told that m∠SRO = 134°, and we are asked to calculate m∠QRO.

In order to do that, we have to realise that since angles SRO and QRO are on a straight line, their measures add up to 180°. Therefore:

∠SRO + ∠QRO = 180°

⇒ 134° + ∠QRO = 180°

⇒ ∠QRO = 180° - 134°

⇒ ∠QRO = 46°

Therefore, m∠QRO = 46°.
