Answer:

4/5 book per hour

Step-by-step explanation:

In this question, we are to rewrite (2/5)/(1/2) as unit rate.

To write this as a unit rate, what we need to do

is to divide 2/5 by 1/2.

That means 2/5 divided by 1/2

Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Step-by-step explanation:

4/5 books/hour

Answer:

It is very easy. Most of the time all you have to do is multiply the two denominators by each other, then multiply the numerators by the opposite numerator.

step-by-step explanation:

For example, if you have 1/3 and 1/4. The common denominator of both is 12, because 4 times 3 = 12. Then you have to multiply the numerators, so it would look like this in the end: 4/12 and 3/12. 4/12 when simplified is 1/3, and 3/12 when simplified is 1/4.

Answer:

RS = 47 units

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

3x + 5 = \(\frac{1}{2}\) ( 2x + 15 + 6x - 37)

3x + 5 = \(\frac{1}{2}\) (8x - 22) = 4x - 11 ( subtract 4x from both sides )

- x + 5 = - 11 ( subtract 5 from both sides )

- x = - 16 ( multiply both sides by - 1 )

x = 16

Thus

RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

The domain of the function \(f(x) = \sqrt{\frac{1}{3}x + 2\) is (d) x  ≥ -6

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

\(f(x) = \sqrt{\frac{1}{3}x + 2\)

Set the radicand greater than or equal to 0

So, we have

1/3x + 2 ≥ 0

Next, we have

1/3x  ≥ -2

So, we have

x  ≥ -6

Hence, the domain of the function is (d) x  ≥ -6

Therefore, the 98% confidence interval for the true proportion of customers who click on ads on their smartphones is approximately (0.369, 0.531).

To compute the 98% confidence interval for the true proportion of customers who click on ads on their smartphones, we can use the formula for a confidence interval for a proportion.

Confidence Interval = Sample Proportion ± (Critical Value) * (Standard Error)

Given:

Sample Proportion (p) = 0.45

Sample Size (n) = 150

Confidence Level = 98%

To find the critical value, we can use a Z-table. For a 98% confidence level, the critical value is approximately 2.33.

The standard error is calculated using the formula:

Standard Error = √((p * (1 - p)) / n)

Plugging in the values, we have:

Standard Error = √((0.45 * (1 - 0.45)) / 150)

≈ 0.0363

Now we can calculate the confidence interval:

Confidence Interval = 0.45 ± (2.33 * 0.0363)

Calculating the upper and lower bounds of the confidence interval:

Upper bound = 0.45 + (2.33 * 0.0363)

≈ 0.531

Lower bound = 0.45 - (2.33 * 0.0363)

≈ 0.369

A recurrence relation is an equation in mathematics that states that the nth term of a series of numbers is equal to some combination of the terms that came before it.

A recurrence relation is an equation in mathematics that states that the nth term of a series of numbers is equal to some combination of the terms that came before it.

For a parameter k that is independent of n, only k preceding terms of the sequence frequently occur in the equation; this number k is known as the order of the relation.

The rest of the series can be determined by continually using the equation if the values of the first  integers in the sequence have been provided.

The nth term in linear recurrences is equivalent to a linear function of the k prior terms. The Fibonacci numbers' recurrence is a well-known example.

r = 6 = radius

V = volume of a sphere of radius r

V = (4/3)*pi*r^3

V = (4/3)*pi*6^3

V = 904.77868423386

V = 904.8

I used my calculator's stored version of pi (instead of something like pi = 3.14)

The units "cubic meters" can be abbreviated to m^3 or \(m^3\)

The volume of the given sphere is 904.8 cubic meters. Thus, option B is the answer.

         The volume of a sphere can be calculated using the formula:

V = \(4/3 * \pi * r^3\),

Where V is the volume and r is the radius of the sphere.

\(\pi\) = 3.14

The radius of the sphere (r) = 6m

Plugging in the given radius of 6m into the formula, we get:

V = (4/3) * \(\pi\) * (6^3)

V = 1.333 * \(\pi\) * 216

V = 1.333 * 3.14 * 216

V = 4.1866 * 216

V = 904.8 cubic meters

Therefore, when the radius of the sphere is 6m, the volume of the sphere is 904.8  cubic meters.

Step-by-step explanation:

The total income and expenditure of Agri-small business limited in September is R 299596 and expenditure is R 193236.

Given that the expenses on petrol be R4850.00 at the end of September, balance is R 106360.00, usage on income of salaries be 25%, on electricity,rates and taxes be 11%, 42% of the remaining on insurance and investments.

We are required to find the total income and expenditure in September.

Generally the equation for insurance is mathematically given as :

Insurance=42% of the balance

Insurance=0.42*0.64A

Insurance=0.2688A.

Generally the equation for the total after all the other expenditures is mathematically given as:

Total expenditure after all other expenditures=0.64A-0.2688A

Total expenditures after all other expenditures=0.3712A.

Total expenditures after all other expenditures is as 111210 (106360+4850)

Equating both the equation and value:

111210=3712A

A=299596

The total income is 299596.

Therefore the calculation of expense is given as:

Expense=0.25A+0.11A+0.2688A+4850

Expense=0.6288A+4850

=0.6288*299596+4850

=193236

The expense is 193236.

The upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

To determine the upper bound of the 95% confidence interval for the average age in the U.S., we can use the sample data from the survey. The sample size is 1072 people, randomly selected from the U.S. population, with a minimum age of 12. By calculating the average age of the respondents, we can estimate the average age of the entire U.S. population.

Using the given information that the average age of the respondents is 43.56 years, and assuming that the sample is representative of the population, we can calculate the standard error. The standard error measures the variability of the sample mean and indicates how much the sample mean might deviate from the population mean.

Using statistical methods, we can calculate the standard error and construct a confidence interval around the sample mean. The upper bound of the 95% confidence interval represents the highest plausible value for the population average age based on the sample data.

Therefore, based on the provided information and calculations, the upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

The probability that the customer is a good risk is 0.70 and the probability that the customer is not a poor risk is 0.957.

To calculate the probability of the customer being a good risk, we need to divide the total number of good risk customers (7732) by the total number of customers (11,102). This gives us 7732/11102 = 0.7000. To calculate the probability of the customer not being a poor risk, we can subtract the total number of poor risk customers (949) from the total number of customers (11,102). This gives us 11102-949 = 10,153. We then divide this number by the total number of customers, giving us 10,153/11,102 = 0.9571. Therefore, the probability that the customer is a good risk is 0.70 and the probability that the customer is not a poor risk is 0.9571.
