Answer:
t1 = $25m
t2 = $(10m + 100)
Step-by-step explanation:
Here we want to write equations
Kiera chose plan 1
$25 monthly and no joining fee
So the amount after m months will be 25 * m
t1 = $25m
Trina chose plan 2
$10 a month and $100 joining fee
after m months , total payment will be
10(m) + 100 = $(10m + 100)
Thus t1 = $25m and t2 = $(10m + 100)

What is the periodic interest rate for an account that is billed monthly with an APR
of 32.99%? Round your answer to the nearest hundredth.
Answer:
The answer is 1.62%
Step-by-step explanation:
A credit card issuer charges an APR of 19.66%
The billing cycle is 30 days
We have to find the periodic interest rate. The periodic rate is found by dividing the APR by the number of billing periods in the year.
The value here becomes:
= 1.615%≈1.62%
Hence, the answer is 1.62%

If P(AB) = 4 and P(B) = .6, then P(ANB) = .667. a.True b. False
If P(AB) = 4 and P(B) = .6, then P(ANB) = .667.
The given statement P(ANB) = 0.667 cannot be evaluated as true or false based on the provided information.
The given information states that P(AB) = 4 and P(B) = 0.6.
The question is to determine if P(ANB) = 0.667.
Let's analyze this using the relationship between the conditional probability P(AB) and joint probability P(A ∩ B).
P(AB) = P(A ∩ B) / P(B)
First, we notice that the given value of P(AB) is 4, which is incorrect because probabilities can only have values between 0 and 1.
However, we will continue with the given values and determine the correctness of the statement P(ANB) = 0.667.
We need to find P(A ∩ B) and use it to verify the statement.
Using the given values:
\(P(A ∩ B) = P(AB) \times P(B) = 4 * 0.6 = 2.4\)
Once again, we find that the calculated probability is outside the range of valid probabilities (0 to 1).
For similar question on probability.
https://brainly.com/question/23417919
#SPJ11
The correct answer is False. The correct value for P(A ∩ B) is 6.67.
In summary, the answer is False.
b. False
The given information is P(AB) = 4 and P(B) = 0.6, and we are asked to determine if P(ANB) = 0.667.
We know that the conditional probability formula is:
P(AB) = P(A|B) * P(B)
However, we need to find P(ANB), which is the joint probability of A and B. We can rearrange the formula to get:
P(ANB) = P(AB) / P(B)
Now, substitute the given values:
P(ANB) = 4 / 0.6
P(ANB) = 6.67 (approximately)
Since P(ANB) ≠ 0.667, the statement is False.

Range = -9 =< f(x) =< 9
Graph 2
Domain = -1 =< x =< 5
Range = -1 =< f(x) =< 2
Explaination:
Domain means the inputed x values on the x-axis, so to make things simpler and to not write every individual x values. We write it with <, >, and =<. (you can see it as the 'width' of a graph).
Range means the output y values on the y-axis. It's like the 'height' of a graph. And also, to make things simpler and to not write every individual y values. We write it with <, >, and =< with f(x) too because f(x) = y.
three women earned a total of £36 they shared the £36 in a ratio 7:3:2 Donna receives the largest amount work out the amount Donna receives .
Answer:
£21
Step-by-step explanation:
We know
Three women earned a total of £36. They shared the £36 in a ratio of 7:3:2. Meaning for every £12, one receives £7, one receives £3, and one receives £2.
Donna receives the largest amount working out the amount Donna receives. Meaning Donna receives £7.
To get from 12 to 36, we time 3.
We take
7 x 3 = £21
So, Donna receives £21

e linear regression function, f(t), that estimates the day's coffee sales with a high temperature
A linear regression function, f(t), that estimates the day's coffee sales with a high temperature is f(t) = -58t + 6,182.
The correlation coefficient (r) is -0.94.
Yes, r indicates a strong linear relationship between the variables because r is close to -1.
How to find an equation of the line of best fit and the correlation coefficient?In order to determine a linear regression function and correlation coefficient for the line of best fit that models the data points contained in the table, we would have to use an online graphing tool (scatter plot).
In this scenario, the high temperature would be plotted on the x-axis of the scatter plot while the y-values would be plotted on the y-axis of the scatter plot.
From the scatter plot (see attachment) which models the relationship between the x-values and y-values, the linear regression function and correlation coefficient are as follows:
f(t) = -58t + 6,182
Correlation coefficient, r = -0.944130422 ≈ -0.94.
In this context, we can logically deduce that there is a strong linear relationship between the data because the correlation coefficient (r) is closer to -1;
-0.7<|r| ≤ -1.0 (strong correlation)

The number of hours, H, of daylight in Madrid as a function of date is approximated by the formula
H=12+2. 4sin(0. 0172(t−80)),
where t is the number of days since the start of the year. (We can think of t=0 as the stroke of midnight on Dec. 31/Jan 1; thus, January falls between t=0 and t=31, February falls between t=31 and t=59, etc. ).
Find the average number of hours of daylight in Madrid (assuming in each case that it is not a leap year):
The average number of hours of daylight in Madrid is approximately 12.01 hours.
To find the average number of hours of daylight in Madrid, we need to integrate the formula for H over the range of days in a year and divide the result by the number of days in a year.
The formula for H is H=12+2.4sin(0.0172(t−80)).
We can integrate this formula over the range of days in a year as follows:
\($\int_{0}^{364} H dt = \int_{0}^{364} (12+2.4\sin(0.0172(t-80))) dt$\)
We can simplify this integral by using the fact that the integral of sin(x) over one period is zero, and the period of sin(0.0172(t−80)) is 2π/0.0172, which is approximately 365. Therefore, we have:
\($\int_{0}^{364} H dt = \int_{0}^{364} 12 dt = 12(365) = 4380$\)
Dividing this result by the number of days in a year, we get:
Average hours of daylight = 4380/365 ≈ 12.01 hours.

A satellite moves in a circular orbit around a planet. Show that the orbital
velocity v and escape velocity of the satellite are related by the
expression
V12 State Kepler's law of planetary motion.
The gravitational force between the satellite and planet can be defined as: F = (G x m1 x m2) / r^2
Where:
F is the gravitational force between the satellite and planet
G is the gravitational constant
m1 is the mass of the planet
m2 is the mass of the satellite
r is the distance between the center of mass of the planet and the satellite.
Since the satellite moves in a circular orbit, its centripetal force is given by:
Fc = m2 x v^2 / r
Where:
Fc is the centripetal force acting on the satellite
v is the velocity of the satellite
r is the radius of the circular orbit.
At the point where the escape velocity is reached, the kinetic energy of the satellite is equal to the potential energy. This expression can be written as:
(1/2 x m2 x vesc^2) - (G x m1 x m2) / r = 0
Where:
vesc is the escape velocity of the satellite.
Equating the above two expressions for Fc and F, we get:
m2 x v^2 / r = (G x m1 x m2) / r^2
Simplifying the above equation, we get:
v^2 = (G x m1) / r
Taking the square root of both sides, we get:
v = sqrt(G x m1 / r)
This is the expression for the orbital velocity of the satellite.
To find the escape velocity, we set v = vesc in the above equation:
vesc = sqrt(2 x G x m1 / r)
This is the expression for the escape velocity of the satellite.
Kepler's law of planetary motion states that:
The orbit of a planet around the Sun is an ellipse with the Sun at one focus.
The line joining the planet and the Sun sweeps out equal areas in equal intervals of time.
The square of the orbital period of a planet is proportional to the cube of its average distance from the Sun.
These laws apply not only to planets around the Sun but also to satellites around planets.

in which:
c is the length of the side opposite to angle C.a and b are the lengths of the other sides.For this problem, the parameters are:
C = 120, a = 8, b = 7.
Hence:
\(c^2 = a^2 + b^2 - 2ab\cos{C}\)

A gift box is in the shape of a trapezoidal prism with base lengths of7 inches and 5 inches and a height of 4 inches. The height of the gift box is 8 inches. What is the volume of the gift box?
Answer:
192 in³
Step-by-step explanation:
A trapezoidal prism is a three dimensional solid that has two similar trapezoids at its top and base.The two similar trapezoids are connected by four rectangles connecting the corresponding sides of the two bases.
The Area of the trapezoid at the top or base = 1/2 (a + b)h
Where a and b are the lengths = 7 inches and 5 inches and the height (h) = 4 inches.
Therefore Area of the trapezoid at the top or base = 1/2 (a + b)h = 1/2(7 + 5)4 = 24 in²
The volume of gift box = Area of the trapezoid at the top or base × height of gift box = 24 × 8 = 192 in³

Consider the standard form equation Ax+By=−24. If the x-intercept is (−3,0) and the y-intercept is (0,12), what are the values of A and B?
Answer:
A = 8 and B = -2 and the equation is:
8x - 2y = -24
Step-by-step explanation:
Line intercepts
Any non-horizontal and non-vertical line has two intercepts: The y-intercept is the point where the line crosses the y-axis, and the x-intercept is the point where the line crosses the x-axis, also called the zero or root.
We are given the equation:
Ax+By=-24
The x-intercept is (-3,0). Substituting the values of x and y:
A(-3)+B(0)=-24
Operating:
-3A = -24
Dividing by -3:
A = -24 / (-3) = 8
A = 8
The y-intercept is (0,12). Substituting and using the just-found value of A
8(0)+B(12)=-24
Operating:
12B = -24
Solving:
B = -2
Thus, A = 8 and B = -2 and the equation is:
