The probability that the total duration of the 500 calls is greater than 18 hours, using the normal distribution, is of:

0.618 = 61.8%.

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Hence, for the total duration of the 500 calls, in seconds, the mean and the standard deviation are given as follows:

[tex]\mu = 500 \times 130 = 65000, \sigma = 30\sqrt{500} = 670.82[/tex]

Each hour has 3600 seconds, hence the number of seconds in 18 hours is given as follows:

3600 x 18 = 64800.

The probability that the total time is greater than 18 hours is one subtracted by the p-value of Z when X = 64800, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (64800 - 65000)/670.82

Z = -0.3.

Z = -0.3 has a p-value of 0.382.

1 - 0.382 = 0.618 = 61.8% probability.

The value of a when the value of 5-a is 20 greater than the vaule of 6a-1 is -2.

Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

Since the value of 5-a is 20 greater than the vaule of 6a-1. This will be:

5 - a > 6a - 1 + 20

Collect like terms

-a - 6a > - 1 + 20 - 5

-7a > 14

Divide

a > 14 / -7

a > -2

Therefore, a is greater than -2.

Answer:

x = 1

y = 7

Step-by-step explanation:

y = -x + 8

-y= -2x - 5 (Switch the signs of y = 2x + 5)

0= - 3x + 3 (Subtract both equations)

3x = 3 (Add 3x on both sides)

x = 1 (Divide by 3 on both sides)

y = -1 + 8 (Plug x as 1 in the equation y = -x + 8)

y = 7 (Simplify)

Leading to the answer

x = 1

y = 7

Answer:

(2a + 3b)(2a - b)

Step-by-step explanation:

4a² + 4ab - 3b²

consider the factors of the product of the coefficient of a² and b² which sum to give the coefficient of the ab- term.

product = 4 × - 3 = - 12 and sum = 4

the factors are + 6 and - 2

use these factors to split the ab- term

= 4a² + 6ab - 2ab - 3b² ( factor the first/second and third/fourth terms )

= 2a(2a + 3b) - b(2a + 3b) ← factor out (2a + 3b) from each term

= (2a + 3b)(2a - b)

The population of the country in 2003 is 302.5 million

From the question, we have the following parameters that can be used in our computation:

Exponential model, A = 302.5e^0.0211t

Where i is the number of years after 2003

In the year 2003, the value of t is 0

i.e. 0 years after 2003

So, we have

A = 302.5e^(0.0211 * 0)

The future value of $8904.56 compounded semi annually is $13,468.95 The interest earned is approximately $4,564.39

The future value of $8904.56 compounded continuously is $66,185.90.

The interest earned is approximately $57,281.34.

When an investment is compounded semi annually, it means that both the amount that was invested and the interest that has already been earned increases in value twice in a year.

The formula for calculating future value:

FV = P (1 + r)^nm

Where:

FV = 8904.56 x 1.03^(7 x 2) = $13,468.95

Interest = future value - amount invested

$13,468.95 -  $8904.56 = $4,564.39

When an amount is compounded continusoly, it increases in value infinitely over the investment time horizon.

The formula for calculating future value when there is continuous compounding is : A x e^r x N

Where:

FV = 8904.56 x e^0.06 x 7 = $66,185.90

Interest = future value - amount invested

$66,185.90 - 8904.56 = $57,281.34

The answer is tom will give 440 cards to Bala, using arithmetic operation.

What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

The total number of cards is 780+240 = 1020.

If in the end Bala will have twice as many cards as Tom then I would divide the 1020 by 3 which equals 340.

So Bala will have 2*340 = 680 cards

Tom will have 340 cards.

Now Bala will need (680-240) = 440 more cards.

Hence Tom will give 440 cards to Bala.

Now if you are going to get another odd number, you have an additional 1/2 (half your chances) or 50% of a chance of getting it after you get the first odd number.

Answer:

x      y

1      0

2     10

5     40

10   90

Step-by-step explanation:

In a linear function, every time x is increased by 1, y is increased by a set amount. The only two complete rows in the table are when x = 1 and x = 5. x is increased four times in that interval while y has increased by 40(40 - 0). This means that every time x increases by 1, y increases by 10(40/4).

Therefore, when x is 2, y will be 10.

To get to ninety, 10 will needed to be added to 0(when x=1) 9 times. 1 + 9 is 10, so x = 10 when y = 90.

Answer:

Step-by-step explanation:

Using these coordinates we find the line equation y=mx+b:

[tex]\displaystyle\\m=\frac{y_2-y_1}{x_2-x_1} \\\\x_1=1\ \ \ \ \ x_2=5\ \ \ \ \ y_1=0\ \ \ \ y_2=40\\\\m=\frac{40-0}{5-1} \\\\m=\frac{40}{4} \\\\m=10\\\\Thus,\ y=10x+b \ \ \ \ (1)\\[/tex]

We substitute the value of coordinate (1,0) into equation (1):

[tex]0=10(1)+b\\\\0=10+b\\\\-10=b\\\\Thus, \ b=-10\\\\Hence,\\\\ y=10x-10\\\\x=2\\\\y=10(2)-10\\\\y=20-10\\\\y=10\\\\Thus,(2,10)\\\\y=90\\\\90=10x-10\\\\100=10x[/tex]

Divide both parts of the equation by 10:
