Answer:

5000 g

Step-by-step explanation:

1 kg = 1000 g

5 kg is 5 times 1 kg

5 * 1 kg = 5 * 1000 g

Answer:

N 7,000.00

Step-by-step explanation:

He earns N 5,000.00 for 10 days of work so divide the 5,000.00 by 10

5,000.00/10= 500.00 ; this is the amount of money he makes in 1 day

Then multiply this amount make in 1 day by 14 to find how much the man makes in 14 days.

500.00*14=7,000.00

Therefore, the man makes N 7,000.00 in 14 days.

Step-by-step explanation:

Step-by-step explanation:

7 × 9 = (? × 9) + (? × ?)

7 × 9 = (3 × 9) + (4 × 9) or (4 × 9) + (3 × 9)

The required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

We have been given numbers are 2, 3, 4, 6, 8, and 9.

To determine numbers create a different expression that is equal to 7 × 9.

Here substitute the numbers 3, 4, and 9, and we get

⇒ 7 × 9 = (3 × 9) + (4 × 9) = 63

⇒ 7 × 9 = (4 × 9) + (3 × 9) = 63

Therefore, the required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.

The three questions are illustrations of arithmetic operations and geometric progressions

(1) Acid concentration

The given parameters are:

pH of acid lemon juice = 2

pH of acid urine = 5.5

The difference between their pH is calculated as follows:

Difference = 5.5 - 2

Difference = 3.5

Multiply the difference by 10, to calculate the acidity

Acidity = 3.5 * 10

Acidity = 35

Hence, the acid like lemon juice is 35 times stronger than urine

(2) Depreciation

The depreciation is given as:

r = 18%

In 1998, the car's worth is $19995.

This is represented as:

a = 19995

2012 is 14 years from 1998.

This is represented as:

n = 14

So, the worth of the car in 2014 is calculated using:

[tex]\mathbf{Worth =a(1 -r)^n}[/tex]

So, we have:

[tex]\mathbf{Worth =19995 \times (1 -18\%)^{14}}[/tex]

Express percentage as decimal

[tex]\mathbf{Worth =19995 \times (1 -0.18)^{14}}[/tex]

[tex]\mathbf{Worth =19995 \times 0.82^{14}}[/tex]

Evaluate

[tex]\mathbf{Worth =1243}[/tex]

Hence, the worth of the car in 2012 is $1243

(3) Spread of Gossip

The spread of the gossip is an illustration of geometric progression, where

a = 1 ---- the first term

r = 3 --- the common ratio

L =1200 --- the last term

So, we calculate the number of terms from 1 to 1200 using the following nth terms of geometric progression

[tex]\mathbf{L = ar^{n-1}}[/tex]

This gives

[tex]\mathbf{1200 = 1 \times3^{n-1}}[/tex]

[tex]\mathbf{1200 = 3^{n-1}}[/tex]

Take logarithm of both sides

[tex]\mathbf{log(1200) = log(3^{n-1})}[/tex]

Apply law of logarithm

[tex]\mathbf{log(1200) = (n-1)log(3)}[/tex]

Divide both sides by log(3)

[tex]\mathbf{n - 1 = log(1200) \div log(3)}[/tex]

[tex]\mathbf{n - 1 =6.45}[/tex]

Add 1 to both sides

[tex]\mathbf{n =7.45}[/tex]

Since the gossip spreads every two minutes.

The total time is:

[tex]\mathbf{Total =2minutes \times 7.45}[/tex]

[tex]\mathbf{Total =14.9\ minutes}[/tex]

Hence, it will take 14.9 minutes for the gossip to spread to 1200 students

According to the discrete distribution given, the standard deviation is of: 0.98.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability, hence:

[tex]E(X) = 0.1296(0) + 0.3456(1) + 0.3456(2) + 0.1536(3) + 0.0256(4) = 1.6[/tex]

The standard deviation is the square root of the sum of the multiplication of each probability and the difference squared between the observation and the mean, hence:

[tex]\sqrt{V(X)} = \sqrt{0.1296(0-1.6)^2 + \cdots + 0.1536(3-1.6)^2 + 0.0256(4-1.6)^2} = 0.98[/tex]

The standard deviation is of 0.98.

Step-by-step explanation:

well, we need to multiply the possibilities of forming a group of 2 boys out of 6 with the possibilities to firm a group of 2 girls out of 5.

the first is 6 over 2

6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15

the second one is 5 over 2

5! / (2! × (5-2)!) = 5×4/2 = 5×2 = 10

so, these 15 possibilities combined with the 10 possibilities makes

15×10 = 150

possibilities to form this committee.

The solution is (x, y) = (-1, 2).

_____

The determinant of the coefficient matrix is ...

  (2)(8) -(5)(3) = 1

The inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. For a 2×2 matrix, that is the original matrix with the diagonal terms swapped, and the off-diagonal terms negated, then divided by the determinant. Since the determinant is 1, the inverse of the coefficient matrix is ...

  [tex]\left[\begin{array}{cc}8&-3\\-5&2\end{array}\right][/tex]

Multiplying this by the constant vector gives the solution vector.

  x = (8)(4) +(-3)(11) = 32 -33 = -1

  y = (-5)(4) +(2)(11) = -20 +22 = 2

Additional comment

Many modern calculators have so many functions that there are likely many you will never use. It is a good idea to learn to use the functions available for solving the kinds of problems you run across. Recent model calculators make it easy to enter matrices and perform various functions on them.

For solving systems of linear equations, the RREF (reduced row-echelon form) function is pretty useful. The bottom row of the result will tell you the kinds of solutions; the right column(s) will tell you what they are.
