A. The probability that he'll win both seats is 0.48.

B. The probability he'll loose both seats is 0.52.

C. The probability he'll win one seat is 0.92.

The probability of an event is calculated using the mathematical notion of probability. We can only use it to determine the likelihood that an event will occur. On a scale from 0 to 1, where 0 denotes impossibility and 1 denotes a specific occurrence.

We are given that a candidate is contesting for both national and provincial seats.

Event A = Winning national seat

Event B = Winning provincial seat

A. The probability that he'll win both seats is

P(A) × P(B) = 0.8 × 0.6 = 0.48

B. The probability he'll loose both seats is

1 - 0.48 = 0.52

C. The probability he'll win one seat is

Probability = 0.8 + 0.6 - 0.48

Probability = 0.92

Answer: To draw a trend line that models the given data set, we first need to plot the points on a graph. We can use a scale of 1 unit on the x-axis and 5 units on the y-axis to plot the points as follows:

(1, 27.5)    ●

(4, 35)      ●

(7, 42.5)    ●

(10, 50)     ●

(13, 57.5)   ●

We can see that the points roughly form a straight line. To find the equation of the trend line, we can use linear regression, which involves finding the line that best fits the data.

Using a calculator or software, we can find that the equation of the trend line is:

y = 3.5x + 24

This means that for every increase of 1 unit in x, y increases by 3.5 units. The y-intercept of the trend line is 24, which represents the value of y when x = 0.

We can plot the trend line on the same graph as follows:

Step-by-step explanation:

The volume of the right cone below is 1152π/3 cubic units then the value of x is 24.

The volume of a right circular cone is given by the formula:

V = (1/3)πr²h

where π is pi (approximately equal to 3.14), r is the radius of the circular base, and h is the height of the cone.

In this problem, we are given that the volume of the cone is 1152π/3 cubic units and that the value of x is related to the radius and height of the cone.

Let's first write the formula for the volume of the cone in terms of x:

V = (1/3)π(x/3)²(x/3)

Simplifying this expression, we get:

V = (1/27)πx²

We are given that V = 1152π/3, so we can substitute this into the formula above and solve for x:

1152π/3 = (1/27)πx³

Multiplying both sides by 27/π, we get:

x³ = 1152*27/3

x³ = 27648

Taking the cube root of both sides, we get:

x = 24

What is verbal sentence ?

Verbal sentences consist of a verb + subject + object or adverbial phrase. The subject and object can be either nouns or pronouns.

After solving the equation we get square of n which is equal to three times of eight

If the subject is a pronoun, it is always a suffix; and if the object is pronoun, it is always a dependent pronoun. When the subject is a pronoun, the word order is normal, meaning that the subject follows the verb and precedes the object.

If the subject is a noun and the object is a dependent pronoun, the pronoun object is before the noun subject.

The dative has a special place in the word-order of verbal sentences. It is expressed by the preposition n in addition to a noun or pronoun referring to a person, if the subject is a pronoun. It assumes a third place following the verb and its subject. However, if the subject is a noun, the dative is allocated a forward position and occurs before the subject.

If the subject is a noun and the object is a pronoun and the sentence consists of a dative, the word order is thus:

Verb + dative + dependent pronoun (object) + subject

The product of 69 and 5.6 x 10⁵ expressed in scientific notation is 3.864 x 10⁷.

Scientific notation, also known as standard form, is a way of writing very large or very small numbers in a concise and convenient way. It expresses a number as the product of a decimal number between 1 and 10 (known as the coefficient) and a power of 10.

The general form of a number written in scientific notation is:

a × 10^n

where a is the coefficient, and n is an integer exponent that indicates the number of places the decimal point must be moved to obtain the original number.

To multiply numbers in scientific notation, we multiply their coefficients and add their exponents.

69 x 5.6 x 10⁵ = (6.9 x 10¹) x (5.6 x 10⁵)

= (6.9 x 5.6) x 10¹⁺⁵

= 38.64 x 10⁶

= 3.864 x 10⁷ (in scientific notation)

Therefore, the product of 69 and 5.6 x 10⁵ expressed in scientific notation is 3.864 x 10⁷.

The shape of sampling distribution of ^p is approximately normal because n < greater than 0.05N and np (1-p) > less than 10.

Step-by-step explanation:

The shape of the sampling distrbution of p is approximately normal because n <= 0.05N and np(1 -p) > 10.

The distribution of the sampling distribution of sample proportions of a proportion p in a sample of size n is defined by the central limit theorem, where:

As long as these two conditions are respected:

n≤ N

np(1-p) > 10.

Here, we have the parameters

n= 700, p = 0.172, N= 15, 000

So, n/N = 0.0466 < 0.05

and, np(1-p)

= 700 x 0.172 ( 1- 0.172)

Answer:

Let's start by finding how much money Mary has left after buying the gift cards:

$250 - $130 = $120

Now, to find the greatest number of candy bars Mary can buy, we need to divide the amount of money she has left by the cost of each candy bar:

$120 ÷ $1.50 = 80

So Mary can buy up to 80 candy bars with the rest of her money.

We can check which inequality represents this situation by plugging in the numbers:

130 + 1.50x ≤ 250

where x represents the number of candy bars Mary buys.

If we subtract 130 from both sides, we get:

1.50x ≤ 120

Finally, if we divide both sides by 1.50, we get:

x ≤ 80

This matches our answer, so the correct inequality is:

D. 130 +1.50x ≤ 250

Answer:

D. 130 +1.50x ≤ 250

√49 is a rational number. √50 is an irrational number. √127 is an irrational number. 125 is a rational number because it is equal to a perfect cube of the whole number 5.

A real number is considered to be irrational if it cannot be written as a simple fraction. It cannot be described using a ratio. When p and q are numbers and q is not identical to 0, N is not equivalent to p/q if N is irrational. An illustration of this is the illogic of the integers

A actual number that's unable to be written as the ratio between two integers—that is, as p/q, where both p and q both are integers—is an irrational number.

√49 is a rational number because it is equal to 7, which is a whole number.

√50 is an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.

√127 is also an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.

125 is a rational number because it can be expressed as 5^3, which is a perfect cube of the whole number 5.

Therefore, the correct statements are:

If to display charts and other educational material, your teacher has requested that two rows of strips be placed around the entire room. the total length of strips is: 4L + 4W.

To find the total length of strips required, we need to know the dimensions of the room. Let's assume that the room has a length of L and a width of W.

If we place two rows of strips around the entire room, one at the top and one at the bottom, the length of each strip will be equal to the perimeter of the room.

The perimeter of the room can be calculated as:

P = 2L + 2W

So, the length of strips required for one row around the room will be:

L1 = P = 2L + 2W

Since we need two rows of strips, the total length of strips required will be:

L2 = 2L1 = 2(2L + 2W) = 4L + 4W

Therefore, the total length is 4 times the length of the room plus 4 times the width of the room.
