Answer:

16 9/10 minutes

Step-by-step explanation:

She is solving 3 questions, so her total time spent =

Total time = Time spent on A + Time spent on B + Time spent on C

30 minutes = 8 7/10 + 4 2/5 + Time C

Time C = 30 minutes - (8 7/10 + 4 2/5)minutes

Time C = 30 minutes - (13 1/0 minutes)

Time C = 16 9/10 minutes

Answer: 16m 54s

Step-by-step explanation:

8 7/10 + 4 2/5 = 13 1/10 or 13m 6s

30m - 13m 6s = 16m 54s

Number of seats in each row is 51 given that a rectangular auditorium seats 2244 people and number of seats in each row exceeds the number of rows by 7. This can be obtained by assuming the value of number of seats in each row, forming quadratic equation and using quadratic formula to find root.

Here in the question it is given that,

We have to find the number of seats in each row.

Let us assume that the number of seats in each row be x.

From the given statement, number of seats in each row exceeds the number of rows by 7, we can write that,

Number of seats in one row = Number of rows + 7

x = Number of rows + 7

⇒ Number of rows = x - 7

Total number of seats in the auditorium can be written as,

⇒ (Number of seats in one row)(Number of rows) = Total number of seats

(x)(x - 7) = 2244

x² - 7x = 2244

⇒ x² - 7x - 2244 = 0

By using quadratic formula we can find the root,

x = (-b ± √b² - 4ac)/2a

here in the question, a = 1, b = -7, c = -2244

√b² - 4ac = √(-7)² - 4(1)(-2244)

√b² - 4ac = √49 + 8976

√b² - 4ac = √9025

√b² - 4ac = 95

x = (-b ± √b² - 4ac)/2a

x = (7 ± 95)/2

x = 102/2 or x = -88/2

⇒ x  = 51 or x = -44

Hence number of seats in each row is 51 given that a rectangular auditorium seats 2244 people and number of seats in each row exceeds the number of rows by 7.

a. (10^7)²

\((10^7)^2 = 10^{(7)(2)} = 10^{14}\)

10^14

Answer:

Q1: dot plot

Q2: box plot

Q3: box plot

Step-by-step explanation:

Question 1 is the dot plot because there is a dot for each playlist. 14 has no dots. Its not the box plot because its doesnt tell you how many times a certain number of playlists appears on the number line, it only gives the ranges of the quartiles and the median.

Question 2 is the box plot because the line that splits the two rectangles is always the median. Therefore the box plot tells you that the median is 13. Its not the dot plot because youd have to pine up all the dots and find the one middle in the middle which takes much longer

Question 3 is the box plot because the interquartile range is the biggest rectangle (from 7 to 15 on the number line). If you find it hard to remember what the interquartile range is, the question will gives clues as to what to look for. In this question it tells you that the interquartile range is 8. We know that range means the gap beweet 2 numbers so just try and find a difference of 8 between 2 of the outlined numbers. Also interquartile sounds like inner quarter so that can help with remembering where it is. Its not the dot plot because its just too simple to quickly find something like the interquartile range.

Remember that the question is only asking which plot makes finding something easier. if you can find what theyre talking about more easily on one of the plots then thats probably the answer.

Hope this helps :)

1.67 pounds flour we get per dollar.

Pound, avoirdupois weight unit equivalent to 16 ounces, 7,000 grains, or 0.45359237 kg, and troy and apothecaries' weight unit equal to 12 ounces, 5,760 grains, or 0.3732417216 kg The symbol lb comes from the Roman predecessor of the contemporary pound, the libra.

Given,

Cost for 2 pounds of flour = $ 1.20

Cost per pound of flour = $ 1.20 /2

                                       = $ 0.20

Now for 2 dollar we get flour = 2 pounds.

for 1 dollar we will get flour = 2/1.20 pounds

                                              = 1.6666 pounds

i.e. for 1 dollar we will get flour = 1.67 pounds.

So, 1.67 pounds flour we get per dollar.

Answer:

52

Step-by-step explanation:

g(-3) = 4(-3)^3 + 3 = -105

g(4) = 4(4)^3 + 3 = 259

AROC = \(\frac{y_{2} - y_{1}}{x_{2} - x_{1}}\) = \(\frac{259 - (-105)}{4 - (-3)}\) = 52

Approximately 7 employees took a break longer than 49 minutes.

We have,

In a box-and-whisker plot, the box represents the interquartile range (IQR), which includes the middle 50% of the data.

The line within the box represents the median.

The "whiskers" extend to the minimum and maximum values, excluding any outliers.

Given the information provided:

Median = 41

Q1 = 37

Q3 = 49

Largest = 55

Smallest = 35

Since Q3 represents the upper quartile and corresponds to the boundary for the upper 25% of the data, we can conclude that 25% of the employees took a break longer than 49 minutes.

Now,

The number of employees who took a break longer than 49 minutes can be estimated by calculating 25% of the total number of employees:

25% of 27 employees

= (25/100) x 27

= 6.75

Since we cannot have a fractional number of employees, we round up to the nearest whole number.

Therefore,

Approximately 7 employees took a break longer than 49 minutes.

Answer:

Step-by-step explanation:

Step-by-step explanation:

To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:

Write the function: f(x) = 1/x^3.

Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Differentiate the function: In our case, n = -3, so the derivative is:

f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.

Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

The least common denominator for the function  \(\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}\)  is     (x -2).

The least common multiple of a group of fractions' denominators is known as the lowest common denominator, or Least Common Denominator.

Calculation for the least common denominator:

Consider the given expression,

\(\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}\)

Further simplifying the equation by factorisation of the denominator part

= \(\frac{11x}{x^{2} +6x-2x-12} -\frac{7}{2x(x -2)}\)

= \(\frac{11x}{(x+6)(x-2)} -\frac{7}{2x(x -2)}\)

= \(\frac{1}{x-2}\)×\([\frac{11x}{(x+6)} -\frac{7}{2x}]\)

Therefore, from the above result, it is found that (x-2) is the least common denominator that can be taken.
