The approximation of 2798.01 to 2 significant figures is 2800
How to round the expression to 2 significant figures?The expression is given as
2798.01
The approximation is given as
2 significant figures
The above means that we approximate the given expression such that only 2 significant figures are left
In this case, the 2 significant figures in the expression 2798.01 are 2 and 7
So, we start the approximation from 9
When 9 is approximated, the expression becomes
2798.01 = 2800
Hence, the approximation of 2798.01 to 2 significant figures is 2800

A survey asked high school cell phone users how many minutes they use their phones to talk each day. The
box plot summarizes the responses.
Between what two numbers do the lower fourth of the responses fall? Put your answer in the box using this
format #and #. Do not include any spaces between the number and the word and when entering your answer.
The lower quartile of the data is said to fall between 1.5 and 2.5 respectively in the box plot that we have here.
How to find the lower quartile from the box plotThe lower quartile is the lower 1/4th of the data distribution. It is the 25th percentile of the distribution that we have in the question.
This point is what is marked at the starting point of the box that we have in this question.
The lower quartile is given by 2 and we can see that that it is bounded by the two numbers of 1.5 and 2.5.

with an average speed of km per hour,a bus takes 10 hour to arrive kathmandu from biratnagar.in how early does it arrive kathmandu,if its average speed is increased by 5 km per hour?
It arrives 1 hour early in Kathmandu, if its average speed is increased by 5 km/h;
Average speed = 45 km/h;
Total time taken to arrive Kathmandu from Biratnagar = 10 hours
∴ Distance between Kathmandu and Biratnagar = Speed × Time
= 45 × 10

Find the quotient of the quantity 30 times ten raised to the negative twenty fourth power end quantity divided by the quantity 5 times ten raised to the negative twenty fourth power end quantity.. write the final answer in scientific notation. 6 x 1048 6 x 1024 6 x 100 6 x 10−48
The quotient of the quantity (30 × 10⁻²⁴)/(5 × 10⁻²⁴) is found out to be 6 × 10⁰.
What is meant by scientific notation?For writing exceptionally large or extremely small numbers, scientific notation is comparable to shorthand. A process is limited to a number multiplied by ten rather than written in decimal form.
In a mathematical equation, the "coefficient" is the first number. The coefficient must be less than ten and greater than one. For example, the coefficient for developing scientific notation for the number 256 is 2.56.As in the equation, the second number is a power of ten, presented as a power of ten with just an exponent, such as 10², which stands for 10 x 10.Now, as per the expressed equitation;
= (30 × 10⁻²⁴)/(5 × 10⁻²⁴)
Divide the numerator (30 × 10⁻²⁴) by denominator (5 × 10⁻²⁴) by the quotient.
= 6 × 10⁰
Therefore, the quotient of the quantity (30 × 10⁻²⁴)/(5 × 10⁻²⁴) is calculated as 6 × 10⁰.

which expression can be used to determine the average rate of change in f(x) over the interval 2, 9?
The necessary expression for calculating the average rate of change inside the given function f(x) is given using :
f'(x) = (f(9) - f(2))/7
What is the average change rate?It quantifies how significantly the function changed per unit on average over that time interval. The slope of the single direction connecting every interval's ends on the function's graph is used to calculate it.
What is the distinction between the slope and the average rate of change?As we can see, slope is another way of calculating the average change rate. The average rate of change is calculated by dividing the difference in the dependent (y-term) by the difference inside the independent variable (x-term). The slope, as well as average rate of change are the same thing.
According to the given data:The function is given to f(x)
The interval is given to be [2,9]
Let a = 2 and b = 9
The expression which is used to determine the average rate of change in f(x) is given by

Today Julia practiced her flute for 9 minutes fewer than twice the amount of time she spent

25 minutes yesterday. How many minutes did she spend practicing the flute today?
50 minutes
O 49 minutes
O 41 minutes
O 36 minutes
Answer:
Julia would have spent 41 minutes.
Step-by-step explanation:
We know that the equation is 2m - 9, and that m is equal to 25.
So all we have to do is solve.
2m - 9
= 2(25) - 9
= 50 - 9
= 41

Given expression( function )
[tex]h(x) = \frac{12}{2x} + 16[/tex]
Thus, plug in -8 in the variable x and solve as follows:-
[tex]h( - 8) = \frac{12}{2( - 8)} + 16[/tex]
Multiply the numbers 2.(-8) = -16
[tex] = \frac{12}{ - 16} [/tex]
Apply the fraction rule
[tex] \frac{a}{ - b} = - \frac{a}{b} [/tex]
[tex] = - \frac{12}{16} [/tex]
[tex] = - \frac{ 12}{16} + 16[/tex]
cancle
[tex] \frac{12}{16} = \frac{3}{4} [/tex]
Factor the number: 12 = 4.3
[tex] = \frac{4.3}{16} [/tex]
Factor the number 16 = 4.4

which of the following is an advantage of a cumulative frequency polygon over a histogram or frequency polygon?
An advantage of a cumulative frequency polygon over a histogram or frequency polygon is that: it can directly compare two or more frequency distributions.
What is a cumulative frequency polygon?A sort of frequency polygon that displays cumulative frequencies is called a cumulative frequency polygon. In other words, the graph adds the cumulative percentages from left to right. On a cumulative frequency polygon's graph, class boundaries are shown along the x-axis and cumulative frequency is shown on the y-axis.Now,
Two alternative methods of graphically presenting data given in the form of a frequency distribution are frequency polygons and histograms. While a histogram can only be created for grouped frequency distribution, the frequency polygon can represent both grouped and ungrouped (discrete) data.Since it is easier to compare the frequencies in cumulative frequency polygon as compared to these two, the former has an advantage over the latter.Hence, an advantage of a cumulative frequency polygon over a histogram or frequency polygon is that: it can directly compare two or more frequency distributions.
