Answer:
Proper: 15/4
Improper: 3 3/4
Step-by-step explanation:
Well to solve the following question,
5/12 + (5/12 + 3/4)
We solve the part in the parenthesis first,
5/12 + 3/4 = 14/4
Simplified -> 7/2
5/12 + 7/2
= 45/12
Simplified -> 15/4
Thus,
the answer is 15/4 or 3 3/4.

Fifty students were given a pre and post test for their math course. Overall, most students increased their scores by 20%
points. The grades on the post test went up to 95%. What is the starting range for the grades on the test?
By percentage , 79.17% is the starting range for the grades on the test.
What does percentage ?
When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of something is 50 percent, and nothing is zero percent. Divide the share of the whole by the whole and multiply the result by 100 to get the percentage.
And the average grade of the 50 students is A.
We know that after it increased by 20%, the average of the grades is 95.
Then we just need to solve the percentage equation:
95 = A*(1 + 20%/100%) = A*(1.2)
95/1.2 = A = 79.17
We conclude that the starting average grade is 79.17%.

What is an advantage of investing pre-tax dollars in a retirement account? (1 point)
A. O You will have that money to live on after you retire.
B. You can work less now because you will have money to spend later.
C. As more time passes after you retire, your payments become larger.
D. If you withdraw the saved money after retirement, you will most likely pay a lower tax rate on it.
If you use pre-tax dollars, then it lowers your taxable income now and most likely when you retire, your income will be lower, so you'll pay a lower tax rate then.

Since the mode is the most frequently occurring data value, it
Select one:
a. is always larger than the mean
b. can never be larger than the mean
c. must have a value of at least two
d. is always larger than the median
e. None of these answers is correct.
Any answer without justification will be rejected automatically.
The correct answer is option (e): None of these answers is correct.
The statement "the mode is the most frequently occurring data value" is true. However, none of the options provided accurately describes the relationship between the mode and the mean.
The mode and the mean are different measures of central tendency and can have different values. There is no general rule or guarantee that the mode will always be larger or smaller than the mean. The relationship between the mode and the mean depends on the specific dataset and its distribution. Therefore, none of the provided options correctly describes the relationship between the mode and the mean.

Explain why the equation of a vertical line cannot be written in point-slope form.
The equation of a vertical line is of the form:
\(x=k\)A vertical line has an infinite slope. The slope-intercept form of a line equation is:
\(y=mx+b\)where "m" is the slope and "b" is the y-intercept. The equation of a vertical line has an undefined slope because the denominator of the slope, i. e, the change in the "x" variable is zero. Therefore, it cannot be written as a slope-intercept form.
assume that for each n, fn is an integrable function on [a, b]. further, assume that the sequence (fn) converges uniformly to f on [a, b]. prove that f is integrable on [a, b].
fn is an integrable function on [a, b]. further, assume that the sequence (fn) converges uniformly to f on [a, b]. f is integrable on integral [a, b].
Let ε > 0. Since (fn) converges uniformly to f on [a, b], there exists an N such that |fn(x) - f(x)| < ε for all x ∈ [a, b] and all n ≥ N.
Since fn is integrable on [a, b], it follows that
∫a b|fn(x)|dx < ∞ for all n ≥ N.
We have
∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ∫a b|fn(x) - f(x)|dx
Since |fn(x) - f(x)| < ε, it follows that
∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ε(b - a)
Since the right hand side is finite, it follows that ∫a b|f(x)|dx is finite. Hence, f is integrable on integral [a, b].

An energy bar company manufactures peanut butter and chocolate bars.
Peanut butter bars cost 25¢ per lb.
The chocolate bars cost 30¢ per lb.
The company sold 260 lbs of bars for $71.
How many of the bars sold were peanut butter?
Answer:
sold 120 chocolate bars
sold 140 peanut butter bars
Step-by-step explanation:
x = peanut butter bars
y = chocolate bars
x + y = 260, total lbs
0.25x + 0.30y = 71, money
solve double variable equation
multiply -4 on both sides for 2nd equation
-x + -1.2y = -284
add both equations together
-0.2y = -24
y = 120
x = 260 - 120
x = 140

In a random sample of students who took the SAT test, 427 had paid for coaching courses and the remaining 2733 had not. Calculate the 95% confidence interval for the proportion of students who get coaching on the SAT .
Answer:
The 95% confidence interval for the proportion of students who get coaching on the SAT is (0.1232, 0.147).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).
427 had paid for coaching courses and the remaining 2733 had not.
This means that \(n = 427 + 2733 = 3160, \pi = \frac{427}{3160} = 0.1351\)
95% confidence level
So \(\alpha = 0.05\), z is the value of Z that has a p-value of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
The lower limit of this interval is:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1351 - 1.96\sqrt{\frac{0.1351*0.8649}{3160}} = 0.1232\)
The upper limit of this interval is:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1351 + 1.96\sqrt{\frac{0.1351*0.8649}{3160}} = 0.147\)
The 95% confidence interval for the proportion of students who get coaching on the SAT is (0.1232, 0.147).
