There are two drama classesoffered at a middle school. The 8th grade class has 13 fewer students than the 7th grade class. If the total number of students in both classes is 67, how many students are in the 8th grade class?
Answers
Answer:
Class 8 has 27 and class 7 has 40
Step-by-step explanation:
8th (r) class has 13 fewer than 7th (x).
x -13 = r
Total for both classes = 67
r + x - 13 = 67
r + x = 80
80 divided by two = 40 (per class)
40 - 13 = 27

Answers
Answer:
8 hours and 26 minutes
Step-by-step explanation:
To convert 506 minutes to hours and minutes, we can use the fact that there are 60 minutes in one hour.
First, we can divide 506 by 60 to find the number of hours:
506 ÷ 60 = 8 with a remainder of 26
This means that 506 minutes is equal to 8 hours and 26 minutes.
Therefore, the conversion of 506 minutes to hours and minutes is:
8 hours and 26 minutes

What are the quadratic functions?Quadratic functions are a type of polynomial function of degree 2, which can be expressed in form f(x) = ax² + bx + c, where a, b, and c are constants, and x is the variable.
The graph of the given quadratic equation y = -x² + 15x - 56 can be plotted using a graphing calculator or any graphing tool. The x-intercepts are the points on the x-axis where the graph intersects the x-axis, i.e., the points where y = 0. By plotting the graph, we can determine the x-intercepts to be (-7, 0) and (8, 0), which correspond to option (c) (-7, 0); (8, 0).
Option (a) and (b) have incorrect x-coordinates for the x-intercepts, and option (d) has both positive x-coordinates for the x-intercepts, which is not correct based on the graph of the given quadratic equation.
Hence, option (c) is the correct answer.

In the monthly payment formula , what value do you give r if the annual interest rate is 7.3%?
Answers
Step-by-step explanation:
For calculating the monthly cost of the loan, you generally need to use the monthly interest payment, which can be derived from the annual interest rate.
Monthly interest rate is calculated by dividing the annual loan costs from 12 (the number of months in one year) and assumption that the loan is compounded monthly.
This is, if the annual interest rate is 7.3%, then the monthly Interest Rate will be:
r = 0.073 / 12 = 0.0060833 (rounded to 7 decimal places) .
When calculating the monthly loan payment, you need to use this value of R in your schedule for calculating the monthly loan payment.
Find the terminal point on the unit circle determined by 5pi over 6 radians.
Use exact values, not decimal approximations.
Answers
The terminal point on the unit circle determined by 5π/6 radians is (-√3/2, 1/2).
To find the terminal point on the unit circle determined by an angle of 5π/6 radians, we need to consider the coordinates of the point (x, y) on the unit circle that corresponds to this angle.
The unit circle has a radius of 1 unit, and the terminal point can be found by using the trigonometric functions cosine and sine.
For the angle 5π/6, the cosine function gives us the x-coordinate, and the sine function gives us the y-coordinate.
Using the exact values of cosine and sine for 5π/6, we have:
cos(5π/6) = -√3/2
sin(5π/6) = 1/2
Therefore, the terminal point on the unit circle determined by 5π/6 radians is (-√3/2, 1/2).

Allie wants to make sure that the pieces of
cloth for a costume are right triangles.
Determine whether the triangle is a right
triangle.
Answers
to know if this is a right triangle, you first add your a^2+b^2.
in this case, it’s 12 and 5. (remember that c^2 is always the biggest number, so you have to add the 2 smallest!)
a and b can be added in any order, it doesn’t matter which one goes first.
a) 12^2 = 144
b) 5^2 = 25
c) 13^2 = 169
now, you add 144+25, if it’s 169, it’s a right triangle, if it’s not then it’s NOT a right triangle.
144+25 does equal to 169 so your answer is, yes it IS a right triangle.
Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $5,000, annual interest: 9%, interest periods: 4, number of years: 18
After 18 years, the investment compounded periodically will be worth $? more than the investment compounded annually.
(Round to two decimal places as needed.)
Answers
After 18 years, the investment compounded periodically (quarterly) will be worth $1,230.23 more than the investment compounded annually.
What is compounded interest?Compounded interest refers to the interest system that charges interest on both principal and accumulated interest.
The period of compounding in a year determines the worth of the future value.
The future value can be ascertained using an online finance calculator as follows:
Interest periods: = 4 times yearly (Quarterly)
Principal = $5,000
Annual interest rate = 9%
Number of years: 18
N (# of periods) = 72 quarters (18 years x 4)
I/Y (Interest per year) = 9%
PV (Present Value) = $5,000
PMT (Periodic Payment) = $0
Results:
Future Value (FV) = $24,815.83
Total Interest = $19,815.83
Interest periods: = Annually
N (# of periods) = 18 years
I/Y (Interest per year) = 9%
PV (Present Value) = $5,000
PMT (Periodic Payment) = $0
Results:
Future Value (FV) = $23,585.60
Total Interest = $18,585.60
Difference in Future Values $1,230.23 ($24,815.83 - $23,585.60)
Thus, an investment compounded periodically earns more than an investment compounded annually.

The Sample standard deviation would be 3.56 and the confidence interval is between72.74 to 78.60.
What is a confidence interval?
A confidence interval is a range of values that is estimated to contain the true value of a population parameter with a certain level of confidence. It is a measure of the uncertainty associated with an estimate of a population parameter, such as the mean, the proportion, or the variance.
a)
sample mean = 75.67
sample std. dev. = 3.56
b)
Given CI level is 90%, hence α = 1 - 0.9 = 0.1
α/2 = 0.1/2 = 0.05, tc = t(α/2, df) = 2.015
\(CI = (xbar - tc * s/\sqrt{n} , xbar + tc * s/\sqrt{n})\\\\CI = (75.67 - 2.015 * 3.56/\sqrt{6} , 75.67 + 2.015 * 3.56/\sqrt{6})\\\\\CI = (72.74 , 78.60)\)

When Makayla runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 1.5 seconds. What is the probability that in a given race, her finishing time will be between 75 and 78 seconds, to the nearest thousandth?
Answers
The probability that in a given race, her finishing time will be between 75 and 78 seconds, using the normal distribution, is of:
0.4772 = 47.72%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for the finishing times are given as follows:
\(\mu = 75, \sigma = 1.5\)
The probability that in a given race, her finishing time will be between 75 and 78 seconds, is the p-value of Z when X = 78 subtracted by the p-value of Z when X = 75, hence:
X = 78:
Z = (78 - 75)/1.5
Z = 2
Z = 2 has a p-value of 0.9772.
X = 75:
Z = (75 - 75)/1.5
Z = 0
Z = 0 has a p-value of 0.5.
0.9772 - 0.5 = 0.4772 = 47.72%.
