Answer:

5√5 cm

Step-by-step explanation:

call the hypotenuse A. the other two sides are B and C.

in a right-angled triangle, A² = B² + C². also, let's just say that B is the side 5cm shorter than hypotenuse.

so we have 15² = (15 - 5)² + C²

225 = (10)² + C²

C² = 225 - 10² = 225 - 100

                      = 125.

C = √125 = √(25 X 5) = √25 X √5  = 5 X √5 = 5√5

Answer:

Tommy delivered 41 newspapers

Step-by-step explanation:

Step 1:  We can convert the percentage to a decimal by either imagining the percentage sign as a decimal and moving it two places to the right or by simply doing the operation 22 / 100, since a percentage is out of 100:

22% = 22.0 = 0.22

22 / 100 = 11 / 50 = 0.22

Step 2:  When dealing with percentage problems, we can use the phrase "y is P% of x" (P% of x is y also works) which allows us to create the equation:  P%x = y, where

Since we're that the pair delivered 186 together and Tommy delivered 22%, we're trying to find what value is 22% of 186.  Thus, we can use the percentage formula above, allow y to represent the unknown, 186 to represent x, and 0.22 to represent P%:

0.22 * 186 = y

40.92

41 = y

Thus, Tommy delivered 41 newspapers.

Answer:

Step-by-step explanation:

The correct answer is d. All of the above causes changes in the CPI to overstate the true inflation rate.

Of total variation in "dependent-variable", the proportion which is explained by variation in "independent-variable" is called (b) coefficient of determination.

The "Coefficient-Of-Determination", denoted as R², is a statistical measure which represents the proportion of total-variation in the dependent variable which can be explained by  variation in "independent-variable".

It quantifies the percentage of dependent variable's variability which can be attributed to the independent variable. A higher coefficient of determination indicates a stronger relationship between the variables, which means that more of variation in "dependent-variable" can be accounted for by changes in the independent-variable.

Therefore, the correct option is (b).

35 and 90 are the minimum and maximum values of the data set.

It means all observations are between those two numbers.

Hence the answer is 100%

Approximately 100% of the observations are between 35 and 90 in the given data set.

What is a median?

In statistics, the median is a measure of central tendency that represents the middle value of a set of data when arranged in ascending or descending order. It divides the data into two equal halves, with 50% of the values falling below the median and 50% falling above it.

To find the median, the data set is first arranged in order from smallest to largest (or vice versa). If the data set has an odd number of observations, the median is the middle value. For example, in a set of {1, 3, 5, 7, 9}, the median is 5.

The five-number summary consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. In this case, the minimum value is 35, and the maximum value is 90. Since these values define the range of the data set, all the observations are between these two values.

Therefore, approximately 100% of the observations are between 35 and 90.

The total population of ducks is 960.

To estimate the total population of ducks, we can set up a proportion using the marked ducks as a sample.

Let's use the following proportion:

Total Ducks / Marked Ducks = Total Marked Ducks / Marked Ducks Counted

Total Ducks / 257 = 960 / 257

Total Ducks x 257 = 960 x 257

Divide both sides by 257 to solve for Total Ducks:

Total Ducks = (960 x 257) / 257

Total Ducks = 960

The metric system is easier to use than the English system for several reasons.

Firstly, the metric system is based on multiples of 10, making conversions between units straightforward. In contrast, the English system has inconsistent conversion factors between units, such as 3 feet in a yard or 16 ounces in a pound, making calculations more complex. Additionally, the metric system uses a consistent set of prefixes to indicate values that are either smaller or larger than the base unit, which further simplifies calculations.

Finally, the metric system is used universally across the world, whereas the English system is only used in a few countries, making it easier for people to communicate and conduct business using a standardized measurement system. In contrast, the English system uses units such as yards, miles, quarts, and gallons, which have inconsistent conversion factors, making calculations more complex and challenging.

"The approximate value of D(4) is 24.6976." Please double-check your calculations and ensure that you correctly evaluated e^(-0.6) in your initial attempt. If you received a different answer, there may have been an error in the calculation.

To evaluate the expression D(4) = 45e^(-0.15(4)), we can follow the order of operations.

First, we simplify the exponent inside the parentheses:

-0.15(4) = -0.6

Next, we substitute this value back into the expression:

D(4) = 45e^(-0.6)

Using the properties of exponential functions, we can rewrite this as:

D(4) = 45 * e^(-0.6)

Now, we can calculate the value of e^(-0.6) using a calculator or mathematical software:

e^(-0.6) ≈ 0.5488 (rounded to four decimal places)

Both expressions are equivalent and represent the same result. So the final answer is that the new position of the submarine in relation to sea level is -1,320 feet.

To find the new position of the submarine in relation to sea level, we need to take into account its initial position and the rate at which it descends.

The submarine starts at a depth of -1,260 feet, so this will be our starting point.
We know that the submarine descends at a rate of 5 feet per minute for 12 minutes. To calculate how far it descends in total, we can multiply the rate by the time:
5 feet/minute x 12 minutes = 60 feet
So the submarine descends 60 feet in total. However, since it is descending, we need to subtract this value from the initial depth of -1,260 feet:
-1,260 feet - 60 feet = -1,320 feet
Therefore, the expression that represents the new position of the submarine in relation to sea level is:
-1,260 - (5 x 12) = -1,320
Alternatively, we could also write this as:
-1,260 + (-5 x 12) = -1,320
Both expressions are equivalent and represent the same result. So the final answer is that the new position of the submarine in relation to sea level is -1,320 feet.

To find the total playtime, we add up all the components:

Total playtime = Combat time + Storytelling time + Exploring time + Puzzle-solving time + Hero creation time

or, Total playtime = c + 2c + 6c + c + 15

We know that the total playtime is 615 minutes, so we can set up the equation:

To find the greatest common factor (GCF) of the given literal terms, we need to identify the highest power of each variable that appears in both terms.

The variables present in both terms are m, n, and p.

For m, the highest power is m⁷ in the first term and m¹ in the second term. Therefore, the common factor for m is m¹.

For n, the highest power is n⁴ in the first term and n¹² in the second term. Therefore, the common factor for n is n⁴.
