To evaluate the expression 1+(-2/3)-(-m) where m = 9/2, we need to substitute the value of m into the expression and simplify it.
What is a mathematical expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
1+(-2/3)-(-m)
1+(-2/3)-(-9/2)
Here, we have to simplify the inner expressions first,
-9/2 can be simplified to -4.5
1+(-2/3)-(-4.5)
Next, we add and subtract the terms:
1-2/3+4.5
Now, we simplify -2/3 by multiplying both numerator and denominator by -1:
1+4/3+4.5
Now, we add the fractions,
1+4/3+4.5
7/3+4.5
Finally, we get the value of the expression as
7/3+4.5 = 4.5 + 7/3 = 25/3.
So the final value of the expression 1+(-2/3)-(-m) where m=9/2 is 25/3.

suppose that someone made a graph of sat scores from 100 randomly selected students from the state of florida. standardized test scores like those for the sat are derived from the students' raw scores (number of questions answered correctly) and adjusted for slight differences in difficulties between versions. what shape would you expect the histogram of this data to be?
The shape of the histogram is expected to be symmetric.
A histogram is a graphical representation of the distribution of a dataset. It is an estimate of the probability distribution of a continuous variable. The histogram is plotted with bin ranges on the x-axis and the frequency (count) of data points that fall within each bin on the y-axis.
The shape of the histogram can give you a sense of the underlying distribution of the data, such as whether it is symmetric or skewed.
Standardized test scores, like the SAT, are typically designed to have a normal distribution, meaning that the majority of scores fall in the middle range, with fewer scores at the extremely high or low ends.
Additionally, because the data is being collected from a large and diverse population of students from one state, it is unlikely that there would be a significant skew in one direction or another.
However, some factors such as socioeconomic status, family background, school district, and student ethnicity may affect the distribution.
Therefore, The shape of the histogram is expected to be symmetric.

If I bought a computer for $420. It had been reduced by 25%.
What was the original price of the computer before the reduction?
(If I could get an answer asap that would be great!)
Answer:
$560
Step-by-step explanation:
if 25% is the discount than the total of the item after the discount is .75x. So to find the original total we need the equation 420=.75x
first we need to isolate x so we divide both sides by .75, doing this will give us 560= x
to check our answer you need to multiply 560 by .75 (which I got by subtracting the discount, .25, from 1) which gives us our discounted total of $420
Given a real number x and a positive integer k, determine the number of multiplications used to find k x 2 starting with x and successively squaring (to find x2 , x4 , and so on). Is this a more efficient way to find k x 2 than by multiplying x by itself the appropriate number of times?
The use of x^2^k is a more efficient way to multiplying than starting with x and successively squaring.

Given the function g(x)=-x²+5x+14, determine the average rate of change of the function over the interval 1 ≤ x ≤ 9
the average rate of change of the function over the interval 1 ≤ x ≤ 9 is 3.75.
What is the average rate of change?It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
Given the function g(x)=-x²+5x+14, within the interval 1 ≤ x ≤ 9
At the lower interval x = 1
g(x) = -1 +5 + 14
g(x) = 18
At the lower interval x = 9
g(x) = -9²+5*9+14
g(x) = -22
The average change of the function will be expressed as:
Δy/Δx = (-22 - 8)/ (9-1)
Δy/Δx = -30/8
Δy/Δx = 3.75
