Answer:
The answer is 24
Step-by-step explanation:
6×4 =24
We can also further simplify it by everything down.
we could use
(3×4) + (3×4)
12 + 12
=24
and we can do the same for
(6×2) + (6×2)
12 + 12

Today Julia practiced her flute for 9 minutes fewer than twice the amount of time she spent
yesterday. If m represents the number of minutes spent practicing yesterday, then the
expression 2m-9 represents how much time she practiced today. JSuppose Julia practiced for
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
So Julia practiced 41 minutes that day.

Out of the incoming freshman at a collage 2,268 of them are female. how many incoming freshman are there if 58% are male?
When out of the incoming freshman at a collage 2,268 of them are female and 58% are male then the total number of freshman is 5400
Given,
Number of females = 2268
Consider the total number students as x
Percentage of male = 58%
Then the equation will become
x-2268= x×[tex]\frac{58}{100}[/tex]
x-2268=0.58x
x-0.58x=2268

Answer:
I answered you in another answer
Step-by-step explanation:
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
f'(x) = (f(b) - f(a))/b - a
f'(x) = (f(9) - f(2))/7
The necessary expression for calculating the average rate of change inside the given function f(x) is given using :

The value of the angle DCH is 72 degrees
How to determine the value of the angle DCH?The given parameters are

DCH = 8x,
DCB = 172°.
The above means that:
11x + 1 + 8x = DCB
This gives
11x + 1 + 8x = 172
Evaluate the like terms
19x = 171
Divide both sides by 19
x = 9
Substitute x = 9 in DCH = 8x,
DCH = 8 * 9

The equation of a circle in the xy-plane is found as (x + 2)² + (y - 1)² = 5.
What is circle?A circle is a two-dimensional closed figure in which the set of all points with in plane is equidistant from the a given point known as the "centre."
Circle Formula: (x - h)² + (y - k)² = r² ;
Where, (h, k) is the centre & r is the radius of the circle.
Use the distance formula for(-2, 1) and (0,2)
[tex]\begin{aligned}&r=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2} \\&r=\sqrt{(0+2)^2+\left(2-1\right)^2} \\&r=\sqrt{(2)^2+\left(1\right)^2}\end{aligned}[/tex]
Further simplifying;
r = √(4 + 1)
r = √5
Centre (h, k) = (-2, 1) Radius (r) = √5.
(x - h)² + (y - k)² = r²
(x + 2)² + (y - 1)² = √5²

The school newspaper wants to find the opinions of students on availability of campus parking. They send a staff member to stand outside a busy dorm and interview students as they walk in or out of the building. What type of sampling process did the paper use?.
The sampling process used by the school newspaper is convenience sampling.
Convenience sampling is the most popular kind of sampling that concentrates on gathering data from individuals (the sample) who are 'convenient' for the researcher to reach. With this sample strategy, researchers can choose subjects at random who are receptive to being contacted and participating in the study rather than selecting participants at random based on any set of criteria (such as demographic variables). This implies that one can locate your sample at any time and any place, such as among individuals in a mall, on the street, at work, or in an online community.

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 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.
