In an ideal circumstance, two people using 56k modems could exchange approximately 448,000 bits of digital information in one minute time. This is equal to 56,000 bytes of data per second (56kbps).

In an ideal circumstance, two people using 56k modems could exchange digital information at a rate of 56 kilobits per second (56kbps). To calculate the amount of data transferred in one minute, we need to multiply 56kbps by 60 seconds. This gives us a total of 3,360 kilobits, or 3.36 megabits. Since one byte is equal to 8 bits, we can divide 3.36 megabits by 8 to get the total number of bytes exchanged. This calculation results in 420,000 bytes, or 448,000 bits, of digital information exchanged in one minute of time.

The radius of convergence of the series sigma cnx9n will be R raised to the power 1/9.

Radius=a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. the length of such a line.

The radius of convergence of the sum of the two series will be 5.

sigma (cnxn + dnxn) = sigma cnxn + sigma dnxn, and if both the series on the right-hand side converge.

The LHS converges for values of x on which both the series on the RHS converge. Hence, the LHS will converge on the intersection of the convergence of the two RHS series.

( if 5 < |x| < 6, the second series will converge, but the first will not.)

The series sigma cnx9n has radius of convergence R raised to the power 1/9.The series sigma cnxn has radius of convergence R. This means that it converges for |x| < R.The series sigma cnx9n can be written as sigma cn(x9)n

This means that the series converges for |x9| < R.

Answer:

Area = 3w^2 - 6w

Step-by-step explanation:

Area = width * length

width = w

length = 3w - 6

Area = w (3w - 6)

Area = 3w^2 - 6w

Answer:

Answer:

To find the difference between the cash price and the hire purchase price, we need to calculate the total hire purchase price.

First, we need to find the outstanding balance after the deposit is paid. We can do this by subtracting the deposit from the cash price:

outstanding balance = cash price - deposit

= Rs 65,000 - Rs 20,000

= Rs 45,000

Next, we need to calculate the total interest to be paid over the 2 1/2 year period. We can do this using the following formula:

total interest = outstanding balance * interest rate * time period

= Rs 45,000 * 18% * 2 1/2 years

= Rs 20,250

Finally, we can add the outstanding balance and the total interest to find the total hire purchase price:

total hire purchase price = outstanding balance + total interest

= Rs 45,000 + Rs 20,250

= Rs 65,250

The difference between the cash price and the hire purchase price is the difference between the total hire purchase price and the cash price. So we can calculate this as follows:

difference = total hire purchase price - cash price

= Rs 65,250 - Rs 65,000

= Rs 250

Therefore, the difference between the cash price and the hire purchase price is Rs 250.

I hope this helps!

= 20 000 + 1.18(65 000 - 20 000)

= 20 000 + 1.18(45 000)

= 20 000 + 53 100

= 73 100

73 100 - 65 000

= 8 100

Therefore, you will spend RS 8 100 more if you buy Hire Purchase Price than the Cash Price of Television.

Answer:

17%

Step-by-step explanation:

Let us say there are 200 people on the JV swim team. That would mean that 110 people do not wear glasses.

Of these 110 people, 30% are in 10th grade. Therefore, 33 people are in 10th grade and do not wear glasses.

This is 33 people ÷ 200 total = 16.5% ≈ 17%

Therefore, there is a 17% probability that a randomly chosen member of the jv swim team does not wear glasses and is in the 10th grade

[NOTE] You could also just do 55% × 30% = .55 × .30 = .165 ≈ .17 ⇒ 17%

Answer:

Step-by-step explanation:

Let x be the number of 1-point shots and y be the number of 2-point shots. We know that the total number of shots is 59 and the total number of points is 99. We can write these two equations as follows:

x + y = 59

1x + 2y = 99

To solve this system of equations, we can use substitution. We can solve the first equation for y and substitute the result into the second equation:

y = 59 - x

1x + 2(59 - x) = 99

1x + 118 - 2x = 99

-x = -19

x = 19

Now that we know the value of x, we can substitute it into the first equation to find the value of y:

y = 59 - 19 = 40
Therefore, the team made 19 1-point shots and 40 2-point shots.

The variable that researchers are trying to explain or predict is called the response variable. It is also sometimes called the dependent variable because it depends on another variable.

Variables used to explain or predict a response variable are called explanatory variables.

The students want to predict age using their height, so the explanatory variable is height and the response variable is age.

Compound interest is the interest you earn on interest. This may be illustrated via way of means of the usage of primary math: in case you have $one hundred and it earns 5% interest every year, you may have $one hundred and five on the cease of the primary year. At the cease of the second one year, you may have $110.25.

The solution of the equation for values of a is 1/(x - 1)

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

a^2x - a = ax

Rewrite properly as

a²x - a = ax

Divide through by a

So, we have

ax - 1 = x

Collect the like terms

ax - x = 1

Factor out x

This gives

a(x - 1) = 1

Divide both sides by x - 1

a = 1/(x - 1)

Hence, the solution is 1/(x - 1)

The inverse function for this problem is defined as follows:

P^(-1)(x) = square root of (x + 100/5), x ≥ -100.

The function in this problem is defined as follows:

P(x) = 5x² - 100, x ≥ 0.

In which P(x) is the profit earned when x tamales are sold.

To obtain the inverse function, first we exchange the variable y = P(x) and x are follows:

x = 5y² - 100

Then the variable y must be isolated as follows:

5y² = x + 100

y² = (x + 100)/5

y = square root of (x + 100/5).

The domain must be the same domain of the square root function, that does not accept negative values hence:

P^(-1)(x) = square root of (x + 100/5), x ≥ -100.

This means that the first option is correct.
