Answer:

225%

Step-by-step explanation:

1. Divide the new weight by the original weight.

90/40 = 2.25.

2. Multiply by 100 to get the percentage.

2.25 x 100 = 225%

The percentage increase of the child from 1990 to 2005 is 125%.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The weight of a child in 1990 was 40 lb. By 2005, the child's weight

had increased to 90 lb.

So, The amount of weight increase is (90 - 40)lb = 50lb.

∴ The percentage increase is,

= (50/40)×100%.

= 125%.

The points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)

Given the following function

f(x) = - 0.5x + 2

g(x) = x^3 - 5x^2 + 3

The point of intersection is the point where f(x) = g(x)

x^3 - 5x^2 + 3 = - 0.5x + 2

x^3 - 5x^2 + 3 + 0.5x - 2 = 0

x^3 - 5x^2 + 0.5x + 1 = 0

Factorize and determine the value of x

x = 0.53 and 4.85

If x = 0.53

f(0.53) = -0.5(0.53) + 2

f(0.53) = -0.265 + 2

f(0.53) = 1.375

If x = 4.85

f(4.85) = -0.5(4.85) + 2

f(4.85) = -2.425 + 2

f(4.85) = -0.245

Hence the points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)

To factor a number, we need to find a prime number that divides it, then we do the division and note the prime number we have got.

Then, we repeat this with the result.

So, starting with 300, we can see that it is divisable by 2, so the first factor is 2.

Making the division, we have:

Now, we repeat with the result, 150.

150 is also divisable by 2, so we have another factor 2:

Now, 75 is divisable by 5, so 5 is the next factor:

15 is also divisable by 5, so:

And 3 is prime, so it is the final factor.

Thus, we have divided by 2, by 2, by 5, by 5 and by 3, so, the factored number is:

The z-score of 235.90, if a normal distribution of scores has a standard deviation of 182.56 and a mean of 265.95, is -0.165.

The mean of the set of data is equal to the sum of all the quantities in the data, and divide by the no of quantities.

Given:

The standard deviation, d = 182.56,

The mean, m = 265.95,

The observation value, X = 235.90

Calculate the z score by the following formula given below,

Z = (X - m) / d,

Here, Z is the Z score,

Z = 235.90 -  265.95 / 182.56

Z =  -0.165

Therefore, the z-score of 235.90, if a normal distribution of scores has a standard deviation of 182.56 and a mean of 265.95, is -0.165.

2 on division by 3/7 yields 14/3.

For the division of two fractions, we need to multiply the first fraction with the reciprocal of the second. Reciprocal of a fraction means interchanging the numerator and denominator ie, the reciprocal of a is 1/a, the reciprocal of p/q = q/p, and so on.

For example, if a/b and c/d are the fractions the a/b ÷ c/d = a/b x d/c =ad/bc.

Implementing the same method to solve this question,

We have 2/1 = 2 as the first and 3/7 as the second fraction. Thus,

2 ÷3/7 =2 x 7/3 = 14/3. So 14/3 is the answer.

Answer:

Step-by-step explanation:

The function f(x) = \(-2(x+4)^2\) + 1 has a greater maximum.

1. The given function is f(x) = \(-2(x+4)^2\) + 1.

2. To find the maximum of the function, we need to determine the vertex of the parabola.

3. The vertex form of a quadratic function is given by f(x) = \(a(x-h)^2\) + k, where (h, k) represents the vertex.

4. Comparing the given function to the vertex form, we see that a = -2, h = -4, and k = 1.

5. The x-coordinate of the vertex is given by h = -4.

6. To find the y-coordinate of the vertex, substitute the x-coordinate into the function: f(-4) = \(-2(-4+4)^2\) + 1 = \(-2(0)^2\) + 1 = 1.

7. Therefore, the vertex of the function is (-4, 1), which represents the maximum point.

8. Comparing this maximum point to the information provided about the other function g(x) on the coordinate plane, we can conclude that the maximum of f(x) = \(-2(x+4)^2\) + 1 is greater than the maximum of g(x).

9. The given information about g(x) is not sufficient to determine its maximum value or specific equation, so a direct comparison is not possible.

10. Hence, the function f(x) =\(-2(x+4)^2\) + 1 has a greater maximum.

Answer:

Step-by-step explanation:

Subjective probability can be defined as the probability of an event happening based on the opinion, personal judgment, perception or experience of a person.

This ultimately implies that, subjective probabilities are not based evidence, quantitative results, facts, historical or empirical data (informations) and as a result, they are considered to be inaccurate.

Hence, subjective probabilities are often inaccurate.

An example of subjective probability is a financial advisor stating that, there is a 20% chance that the price of a security will increase by next week.

The modal class is 70 - 80 and the mean speed is 66.4

The table of values is given as:

Speed    Frequency

40 - 50          10

50 - 60          16

60 - 70          19

70 - 80          23

80 - 90          12

The modal class is the class with the highest frequency

The class 70 - 80 has the highest frequency of 23

Hence, the modal class is 70 - 80

Rewrite the frequency table to include the class midpoints

45          10

55          16

65          19

75          23

85          12

The estimate of the mean speed is then calculated as:

\(\bar x =\frac{\sum fx}{\sum f}\)

So, we have:

\(\bar x = \frac{45* 10 + 55 * 16 + 65 * 19 + 75 * 23 + 85 * 12}{80}\)

\(\bar x = 66.4\)

The angles COA and POC are 22.5 and 67.5 degrees respectively as POA is a right angled triangle.

POA is a right angle so it is 90 degrees.

POC +COA = 90  .....(1)

Also, POC is 3 times as large as COA.

Let's take COA, "x"

POC = 3x

Substituting the values in equation (1) as follows:

x + 3x = 90

4x = 90

x= 22.5

Answer: 21:9 and 42:18

Step-by-step explanation:

14:6 at its most basic form is 7:3, so find anything that could be equal to this if a number is multiplied on both sides.

21:9 is our simplified ratio multiplied by 3 on both sides.

42:18 is our simplified ratio multiplied by 6 on both sides.

But, the final ratio doesn't work, because 7 and 3 respectively cannot multiply to 13 and 8 with the same value.

The required value of x is 49.

A mathematical expression is a phrase that contains a minimum of two numbers or variables and at least one mathematical procedure. It is possible to multiply, divide, add, or subtract in arithmetic.

Simplifying the left side of the equation, we get:

x - (-1) = x + 1

So the equation becomes:

x + 1 = 50

Subtracting 1 from both sides, we get:

x = 49

Therefore, the value of x is 49.

Step-by-step explanation:

The area of the shaded sector of the circle is 7.27 m^2

The area of a circle is the amount of two-dimensional space taken up by the circle. It can be calculated by using the formula A = πr2, where A is the area, π is 3.14, and r is the radius of the circle. The radius is the distance from the center of the circle to any point on the circle. The diameter of a circle, which is the distance from one side to the other, is twice the radius. Therefore, the area of a circle can also be calculated by using the formula A = πd2/4, where d is the diameter of the circle.

The area of the shaded sector of the circle is 7.27 m^2.

This can be calculated using the formula A = (π/180) x r^2 x θ, where r is the radius (18 m in this case), and θ is the angle in degrees (110° in this case).

Therefore, A = (π/180) x (18^2 x 110) = 7.27 m^2.

Answer:

Table C

Step-by-step explanation:

Given

Table A to D

Required

Which shows a proportional relationship

To do this, we make use of:

\(k = \frac{y}{x}\)

Where k is the constant of proportionality.

In table (A)

x = 2, y = 4

\(k = \frac{y}{x}\)

\(k = \frac{4}{2}\)

\(k = 2\)

x = 4, y = 9

\(k = \frac{y}{x}\)

\(k = \frac{9}{4}\)

\(k = 2.25\)

Both values of k are different. Hence, no proportional relationship

In table (B)

x = 3, y = 4

\(k = \frac{y}{x}\)

\(k = \frac{4}{3}\)

\(k = 1.33\)

x = 9, y = 16

\(k = \frac{y}{x}\)

\(k = \frac{16}{9}\)

\(k = 1.78\)

Both values of k are different. Hence, no proportional relationship

In table (C):

x = 4, y = 12

\(k = \frac{y}{x}\)

\(k = \frac{12}{4}\)

\(k = 3\)

x = 5, y = 15

\(k = \frac{y}{x}\)

\(k = \frac{15}{5}\)

\(k = 3\)

x = 6, y = 18

\(k = \frac{y}{x}\)

\(k = \frac{18}{6}\)

\(k = 3\)

This shows a proportional relationship because all values of k are the same for this table
