Answer:

(a) 20 + 14(s)

(b)$146

Step-by-step explanation:

Use s as your variable per session.

$20 is a flat fee as a sign up for tutoring.

Therefore, 20 + 14s is the expression.

(b) 14x9=126 + 20 = 146

Answer:

32 m^2

Step-by-step explanation:

Quite easy. The altitude of the triangle is 8m. The base of the triangle is 2 + 6. The base is 8 meters and the height of the triangle is 8 meters. The area ofa triangle is base * height divded by 2.

(8 * 8)/2 = 32 sqaure meters

In 2013, the population of China was estimated to be 1,360,760,100. Round off the number of people

Aleksandr [31]

Answer:

a) 1,360,760,000

b) 1,361,000,000

c) 1,400,000,000

d) 1,360,800,000

Step-by-step explanation:

We have to round off the given population number to certain digits.

The following are the rules to round of a number:

First identify the digit to be rounded.
If this digit is followed by 5,6,7,8,9 then we round up the number that is increase the digit by 1 and all the numbers to right becomes zero.
If this digit is followed by 0,1,2,3,4 then we round down the number that is decrease the digit by 1 and all the numbers to right becomes zero.

a) to the nearest thousand.

Thousands place: 0

Right Digit: 1

We round down the number

Rounded to the nearest 1,000 or t he thousands Place = 1,360,760,000

b) to the nearest million

Millions place: 0

Right Digit: 7

We round up the number

Rounded to the nearest million places = 1,361,000,000

c) to nearest hundred million

Hundred million place: 3

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,400,000,000

d) to the nearest hundred thousand.

hundred thousand place: 7

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,360,800,000

What is 25-3x=10 broken down

Tema [17]

Answer:

The answer is x = 5

Step-by-step explanation:

The given equation is

25 - 3x = 10

So when we break down this equation, we will have the value of x. Now breaking down the equation and moving variables to the correct positions.

25 - 3x = 10

Moving -3x and 10 to the other sides

25 - 10 = 3x

3x = 25 - 10

3x = 15

Now dividing both sides with 3, we get the following answer

3x/3 = 15/3

x = 5

Breaking down the equation gives us the value of x, i-e 5

Please solve the following question.

The expected number of defective sample is 0.25

<h3>The probability distribution</h3>

The given parameters are:

Population, N = 30
Sample, n = 2
Selected, x = 4

Start by calculating the defective proportion using:

$p = \frac{x}{N}$

So, we have:

p = 4/30

p = 0.13

The probability distribution is calculated as:

$P(x) = ^nC_x * p^x *(1 - p)^{n - x}$

So, we have:

$P(0) = ^2C_0 * 0.13^0 *(1 - 0.13)^{2 - 0} = \frac{19}{25}$

$P(1) = ^2C_1 * 0.13^1 *(1 - 0.13)^{2 - 1} =\frac{23}{100}$

$P(2) = ^2C_2 * 0.13^2 *(1 - 0.13)^{2 - 2} = \frac{1}{100}$

So, the probability distribution is:

x 0 1 2

P(x) 19/25 23/100 1/100

<h3>The expected number of defective sample</h3>

This is calculated using:

$E(x) = \sum x * P(x)$

So, we have:

E(x) = 0 * 19/25 + 1 * 23/100 + 2 * 1/100

Evaluate

E(x) = 0.25

Hence, the expected number of defective sample is 0.25

A mourning dove can reach speeds up to 35 miles per hour. how fast is this in feet per hour

Bad White [126]

1 mile = 5,280 feet

so 35 miles are 35*5,280=184,800 feet.

The speed of the mourning dove is :

$s=\frac{35miles}{hour}= \frac{184,800feet}{hour}= 184,800\frac{feet}{hour}$

Answer: $184,800\frac{ft}{h}$
