20% of Aussies have blue eyes. If 4 Aussies in a play group have blue eyes, how many Aussies are in the group?

Answers

Answer 1

Answer:

20

Step-by-step explanation:

Step 1: 4 = 20% × Y

Step 2: 4 = 20/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:

Step 3: Y = 4 × 100/20

Step 4:Y = 4 × 100 ÷ 20

Step 5: Y = 20

Answer 2

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

20% = 4

100% = 20

The total number of people in the group is 100 people.

What is a percentage?

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

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

We have,

Number of Aussies with blue eyes = 4

Percentage of blue eyes in the Aussies = 20%

This can be written as:

20% = 4

Now,

The percentage of the total number of people in the group = 100%

So,

20% = 4

Multiplying 5 on both sides.

5 x 20% = 5 x 4

100% = 20

This means,

The total number of people in the group is 100.

Thus,

The total number of people in the group is 100 people.

A binary communication channel carries data as one of two sets of signals denoted by 0 (zero) and 1. Owing to noise, a transmitted 0 is sometimes received as a 1, and a transmitted 1 is sometimes received as a 0. For a given channel, it can be assumed that a transmitted 0 is correctly received with probability 0.95 and a transmitted 1 is correctly received with probability 0.75. Also, 70% of all messages are transmitted as a 0. If a signal is sent, determine the probability that a 1 was received.

Answers

Answer:

26% probability that a 1 was received.

Step-by-step explanation:

We have these following probabilities:

70% probability that a message is transmitted as a 0.

100 - 70 = 30% probability that a message is transmitted as a 1.

If a message is transmitted as a 0, 95% probability of being received as a 0 and 5% probability of being received as 1.

If a message is transmitted as a 1, 75% of being received as a 1 and 25% probability of being received as a 0.

If a signal is sent, determine the probability that a 1 was received.

5% of 70%(Sent 0, received 1) of 75% of 30%(sent 1 and received 1). So

[tex]p = 0.05*0.7 + 0.75*0.3 = 0.26[/tex]

26% probability that a 1 was received.

Answer:

x=-3 ,y=4

Step-by-step explanation:

x+5y=17------(i)

-4x+3y=24------(ii)

use substitution method

x+5y=17

make x subject of the formula

x=17-5y-----(iii)

substitute equation (iii) into equation (ii)

-4x+3y=24

-4(17-5y)+3y=24

-68+20y+3y=24

23y=24+68

23y=92

divide both sides by 23

y=92/23

y=4

substitute y in equation (iii)

x=17-5y

x=17-5(4)

x=17-20

x=-3

Josh deposited 1500 into a savings account at his nearby bank. The bank’s interest rate is 3%. He does not deposit or withdraw any money for the next 4 years. How much interest will he gain after the fourth year?

Answers

Answer:

188.27

Step-by-step explanation:

divide the starting number (1500) by 100 to get 1% then times by 3 to get the new number for tje start of tje next year.

After 1st- 1545

after 2nd year = 1591.35

After 3rd = 1639.1005

After 4th= 1688.273515

what he gained is 1688.273515-1500= 188.273515.
