Addition of the fractions showed that the total amount applied is 39/10 kg

The addition of fractions is a little different from the normal addition of numbers since a fraction has a numerator and a denominator which is separated by a bar. The addition of fractions can be easily done if the denominators are equal. While like fractions have common denominators, unlike fractions are converted to like fractions to make addition easier.

In this case, we simply need to add the fraction of nitrogen, phosphorous and potassium.

This becomes;

6/3 + 2/5 + 6/4 = 2 + 2/5 + 3/2 = 39/10 = 3.9kg

The amount added is 39/10kg or 3.9kg

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.

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

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.

The probability that exactly 10 of the citizens favor the building of the health center is;

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 )

The probability that X > 1 and Y > 0 here is computed as:

The geometric mean between 5 and 125 will be 25.

What is geometric mean?

The sequence where each word is varied by another by a common ratio is known as a geometric progression or geometric sequence. When we add a constant (which is not zero) to the term before it, the sequence's subsequent term is created. The following symbols stand in for it: a, ar, ar2, ar3, ar4, etc.

The Geometric Mean (GM) is the average value or mean that, in mathematics, represents the centre tendency of a group of numbers by calculating the product of their values. In essence, we multiply the numbers collectively and take the nth root of the resulting multiplied numbers, where n is the total number of data values.

The given number is 5, 125.

So the Geometric Mean willl be (5*125)[tex].^{1/2}[/tex]

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

4th blank: 13

5th/6th blank: 14/13

7th blank: 42

Step-by-step explanation:

From the first line to the second you need to add

4/7x + 5/14x

Times 2 on the top and bottom of 4/7 to make it be 8/14.

then you can add:

8/14x + 5/14x

Keep the 14 on the bottom, add the tops. 8+5 is 13

= 13/14x

The 13 on top is the first fill in.

To solve for x you can multiply by the reciprocal of 13/14 (just flip it over)

14/13 is the blank/blank on both sides of the equal sign in front of the parenthesis.

The blank over 14 is 13, the same as the first answer.

The 14/13 × 13/14x

just leaves x on the left in the last line of the equation.

On the right, you have

14/13 × 39

You can divide the 39/13 to get 3. The problem becomes

14 × 3

13/14 x = 39

14/13(13/14x)=14/13(39)

A function is an expression that shows the relationship between the independent variable and the dependent variable.  A function is usually denoted by letters such as f, g, etc.

Given that: the product of two numbers x and y whose sum is 16. Thus:

f(x) = x × y  ---- (1)

x + y = 16   ---- (2)

Put (3) in (1):

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

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.

Answer:

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°.
