The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The population has increased by 51.56% from last year to this year.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of population last year = 2,639,000,000

Number of population this year = 3,999,635,444

The best estimate of the total population of last year and this year.

= [ (3,999,635,444 - 2,639,000,000) / 2,639,000,000 ] x 100

= ( 1360635444 / 2,639,000,000 ) x 100

= 51.56 %

Thus,

The population has increased by 51.56% from last year to this year.

How to add heterogeneous fractions:

Heterogeneous fractions are fractions that have different denominators.

To add heterogeneous fractions, follow these steps:

a) Green is 0.3, Yellow is 0.1

b) There are 12 green pins in the bag

Given,

In the question:

There are some colored pins in a bag. The pins can be green, yellow, purple, or grey. A pin is going to be taken at random from the bag.

The table shows the probabilities of picking a purple or grey pin.

The table is not given in the question :

So, The table is :

Colors:          Green         Yellow      Purple        Grey

Probability:                                         0.35           0.25

To find the :

a)Complete the table.

There are 14 purple pins in the bag.

b)Work out how many green pins are in the bag.

Now, According to the question:

The probability is the ratio between the possible outcomes over the total outcomes:

The value of the probability of possible outcomes is greater than 0 and smaller than 1 (0 < P < 1)

The sum of the probabilities of all outcomes must equal 1.

A bag contains some green, yellow, purple and grey pins

∵ The probability of picking a purple pin P(purple) = 0.35

The probability of picking a grey pin P(grey) = 0.25

→ The total of all possible outcomes is 1

The sum of the probability of green and yellow pins = 1 - 0.35 - 0.25

The sum of the probability of green and yellow pins = 0.4

P(green) + P(yellow) = 0.4 ⇒ (1)

∵ The probability of picking a green pin is 3 times the probability

of picking a yellow pin

P(green) = 3 P(yellow) ⇒ (2)

→ Substitute (2) in (1)

3 P(yellow) + P(yellow) = 0.4

4 P(yellow) = 0.4

→ Divide both sides by 4

P(yellow) = 0.1

The probability of picking a yellow pin is 0.1

→ Substitute P(yellow) in (20 by 0.1

P(green) = 3(0.1)

P(green) = 0.3

The probability of picking a green pin is 0.3

Green = 0.3, Yellow = 0.1

There are 14 purple pins in the bag

P(purple) = 0.35

0.35 of purple pins = 14

→ To find the total number of pins in the bag divide 14 by 0.35

The total number of pins = 14 ÷ 0.35

The total number of pins = 40 pins

P(green) = 0.3

The number of green pins = 0.3 × 40

The number of green pins = 12 pins

Hence, There are 12 green pins in the bag.

1)  An expression for the amount of fabric needed to make 13 pairs of wings is; 3/4 * $8 = $6 each

2) An expression of the total cost is; 3/4 * $8 * 13 = $78

3) The way we will use  associative and commutative properties is to start by treating 1 yard of fabric like the fraction 4/4.

4) Simplifying equals $78

We are told that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Thus;

1) 3/4 * $8 will give us the cost of the amount required for 3/4 yard of fabric.  3/4 * $8 = $6 each

2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such;

Amount needed to make 13 pairs is expressed as; 3/4 * $8 * 13 = $78

3) Treat 1 yard of fabric like the fraction 4/4.

Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.

This pattern is easier  because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.

4) Simplifying the expression gives; $78

Question is incomplete. Answering in a general way;

The side CA has a length of  [tex]\sqrt{c^{2}-b^{2} }[/tex] and Angle C is of 28 degrees.

Given,

Right angled triangle ABC

Length of side AB = b

Length of side BC = c

Angle B = 62°

Angle A = 90°

We have to find the length of side CA and Angle C;

Here,

According to Pythagorean theorem,

Hypotenuse = [tex]\sqrt{base^{2}+altitude^{2} }[/tex]

Here,

Altitude = [tex]\sqrt{Hypotenuse^{2} -Base^{2} }[/tex]

CA = [tex]\sqrt{c^{2} -b^{2} }[/tex]

Now,

Sum of interior angles of a triangle is 180°

Then,

∠A + ∠B + ∠C = 180°

So,

90° + 62° + ∠C = 180°

∠C = 180° - 152°

∠C = 28°

The study in question is an observational one. No treatments were used in the study because there were none.

b) Since the 200 patients who made up the random sample were divided into groups without regard to their physical health.

When patients are divided into groups at random, it may be discovered that one group's patients are in better health than the other. The results then might become skewed. Therefore, our study's conclusion might be false.

Probability = the number of possible paths to success / The total number of outcomes. That is a chance of getting an event

The formula for calculating an event's probability is the ratio of favorable outcomes to the total number of outcomes. Probabilities are always between 0 and 1. Probability = Number of Favorable Outcomes / Total Number of Outcomes is the general probability formula.

Given:

Number of red tiles = 14

Number of blue tiles = 20

Number of green tiles = 16

total number of tiles = 14+20+16=50

P(blue) = number of blue tiles / total number of tiles
