Answer:
1
Step-by-step explanation:
The probability of an event occurring is the ratio of the possible outcome to the total outcome. In this case, 15 friends were chosen and the choices are either strawberry or vanilla.
Since there are no other flavors, a friend picked at random will either pick strawberry or vanilla.
Therefore probability that this friend's favorite flavor is either strawberry or vanilla is 1.
A sequence starts 1, 4, 9, 16 ... The nth term is n^2. Use this fact to find the nth term of the following sequences: a) 2, 5, 10, 17 b) 2, 8, 28, 32
Answer:
n²+1
2n²
Step-by-step explanation:
We can see that 2, 5, 10, and 17 becomes 1, 4, 9, and 16 when we subtract 1.
So it adds 1. The nth will be n² + 1.
2, 8, 18, and 32 is the double of n². 1, 4, 9, and 16 are their half.
So the nth term becomes 2n².
The value of the equation is
a) The nth term of the equation is Aₙ = n² + 1
b) The nth term of the equation is Bₙ = 2n²
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
a)
Let the nth term of the equation be represented as Aₙ
Now , the sequence is
P = { 2 , 5 , 10 , 17 , .. }
when n = 1 , P₁ = 2
when n = 2 , P₂ = 5
So , the equation for the nth term is Aₙ = n² + 1
b)
Let the nth term of the equation be represented as Bₙ
Now , the sequence is
Q = { 2 , 8 , 18 , 32 , .. }
when n = 1 , P₁ = 2
when n = 2 , P₂ = 8
So , the equation for the nth term is Bₙ = 2n²

Step-by-step explanation:
A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 higher than in the first. The tax in the first city was 7.5%, and the tax in the second city was 5%. The total hotel tax paid for the two cities was $825. How much was the hotel charge in each city before tax?
The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.
Let x be the hotel charge before tax in the first city, and y be the hotel charge before tax in the second city. Then we have:
y = x + 1500 (the hotel charge before tax in the second city was $1500 higher than in the first)
0.075x + 0.05y = 825 (the total hotel tax paid for the two cities was $825)
We can use the first equation to solve for y in terms of x:
y = x + 1500
Then we can substitute this expression for y into the second equation:
0.075x + 0.05(x + 1500) = 825
Simplifying this equation, we get:
0.075x + 0.05x + 75 = 825
0.125x = 750
x = 6000
So the hotel charge before tax in the first city was $6000. Using the first equation, we can find the hotel charge before tax in the second city:
y = x + 1500
y = 6000 + 1500
y = 7500
So the hotel charge before tax in the second city was $7500.
Therefore, the answer is: The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.

Which statements are supported by the data in the table? Check all that apply.
The mean number of cars sold in a month is the same at both dealerships.
The median number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The range of the number of cars sold is the same for both dealerships.
The data for Admiral Autos shows greater variability.
The statements supported by the data in the table are:
The mean number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The data for Admiral Autos shows greater variability.
To determine which statements are supported by the data in the table, let's analyze the given information:
The mean number of cars sold in a month is the same at both dealerships.
To calculate the mean, we need to find the average number of cars sold each month at each dealership.
For Admiral Autos:
(4 + 19 + 15 + 10 + 17) / 5 = 65 / 5 = 13
For Countywide Cars:
(9 + 17 + 14 + 10 + 15) / 5 = 65 / 5 = 13
Since both dealerships have an average of 13 cars sold per month, the statement is supported.
The median number of cars sold in a month is the same at both dealerships.
To find the median, we arrange the numbers in ascending order and select the middle value.
For Admiral Autos: 4, 10, 15, 17, 19
Median = 15
For Countywide Cars: 9, 10, 14, 15, 17
Median = 14
Since the medians are different (15 for Admiral Autos and 14 for Countywide Cars), the statement is not supported.
The total number of cars sold is the same at both dealerships.
To find the total number of cars sold, we sum up the values for each dealership.
For Admiral Autos: 4 + 19 + 15 + 10 + 17 = 65
For Countywide Cars: 9 + 17 + 14 + 10 + 15 = 65
Since both dealerships sold a total of 65 cars, the statement is supported.
The range of the number of cars sold is the same for both dealerships.
The range is determined by subtracting the lowest value from the highest value.
For Admiral Autos: 19 - 4 = 15
For Countywide Cars: 17 - 9 = 8
Since the ranges are different (15 for Admiral Autos and 8 for Countywide Cars), the statement is not supported.
The data for Admiral Autos shows greater variability.
To determine the variability, we can look at the range or consider the differences between each data point and the mean.
As we saw earlier, the range for Admiral Autos is 15, while for Countywide Cars, it is 8. Additionally, the data points for Admiral Autos are more spread out, with larger differences from the mean compared to Countywide Cars. Therefore, the statement is supported.
Based on the analysis, the statements supported by the data are:
The mean number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The data for Admiral Autos shows greater variability.

14. Find 5he equation of the parabola with a vertex at (-4,-1) and passing through the point (-2, -3).
Answer:
=> the passing point's y cord is lower than vertex, meaning it is a reflection
\(y=-a\left(x+h\right)^{2}-k\)
=>Apply the vertex to hk form
\(y=-a\left(x+4\right)^{2}-1\)
=> Find a by plugging X and Y of the passing through point
\(-3=-a\left(-2+4\right)^2-1\)
=> solve
\(-4a-1+1=-3+1\)
\(a=\frac{1}{2}\)
Therefore the equation for this is,
\(y=-\frac{1}{2}\left(x+4\right)^{2}-1\)
Answer:
\(y=-\dfrac{1}{2}(x+4)^2-1\)
Step-by-step explanation:
Vertex form: \(y=a(x-h)^2+k\)
where:
\((h, k)\) is the vertex\(a\) is some constantGiven:
vertex = (-4, -1)point on parabola = (-2, -3)Substitute given values into the formula to find \(a\):
\(\implies -3=a((-2)-(-4))^2+(-1)\)
\(\implies -3=a(2)^2-1\)
\(\implies -3=4a-1\)
\(\implies -2=4a\)
\(\implies a=-\dfrac{2}{4}=-\dfrac{1}{2}\)
Therefore, the equation of the parabola is:

If the equation ar+b=cr + d has no solution, like in the example below, what must be true about a b c and d?
Answer:
See below.
Step-by-step explanation:
For an equation like \(\displaystyle \large{ar+b=cr+d}\) to have no solution, the equation has to be false.
To make an equation false, we let a = c. That’d make a and c have same value, when we transport cr to subtract ar, we’ll get 0.
So if a = c, the equation is \(\displaystyle \large{b=d}\) now that we have b = d. The equation has to be false to have no solutions, hence b and d must not equal to one another.
Summary
When a = c, the new equation is b = d as ar and cr having same value, when subtracted, the remain is 0+b=d.b = d means that the value of b and d are equal but that makes the solutions to be infinitely many. Therefore, we cannot let b = d.From second, b ≠ d.a = c but b ≠ dLet me know if you have any questions regarding this question or for clarification.

Evaluate z- (y-z) if z= 4 and y =6
Answer: 2
4 – (6-4) = 2
Answer: 2- (y= 6 , z=2)
Step-by-step explanation:
If z = 4 and y = 6, then we can substitute these values into the expression:
z - (y - z) = 4 - (6 - 4)
Expanding the subtraction in the parentheses, we get:
z - (y - z) = 4 - (6 - 4) = 4 - (2) = 4 - 2
Finally, solving for the subtraction:
z - (y - z) = 4 - 2 = 2
So, the value of the expression z - (y - z) when z = 4 and y = 6 is 2.
The Kaumajet Factory produces two products - table lamps and desk lamps. It has two separate departments - Finishing and Production. The overhead budget for the Finishing Department is $550,000, using 500,000 direct labor hours. The overhead budget for the Production Department is $400,000 using 80,000 direct labor hours.
The Kaumajet Factory will allocate $7.20 of factory overhead to each unit of table lamp using the multiple production department factory overhead rate method with an allocation base of direct labor hours.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Predetermined overhead rate for Finishing Department = $550,000 / 500,000 direct labor hours = $1.10 per direct labor hour
Predetermined overhead rate for Production Department = $400,000 / 80,000 direct labor hours = $5.00 per direct labor hour
For one unit of table lamp, 2 hours of finishing and 1 hour of production are required, so the total direct labor hours for one unit of table lamp is 2 + 1 = 3 hours.
Finishing Department overhead cost per unit of table lamp = 2 hours * $1.10 per direct labor hour = $2.20
Production Department overhead cost per unit of table lamp = 1 hour * $5.00 per direct labor hour = $5.00
Total factory overhead cost per unit of table lamp
$2.20 + $5.00 = $7.20
Therefore, the Kaumajet Factory will allocate $7.20 of factory overhead to each unit of table lamp using the multiple production department factory overhead rate method with an allocation base of direct labor hours.

During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?
Answer:
2 or 200%
Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week, 6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week
In Exercises 1 to 8, find the limit of each sequence that converges; if the sequence diverges, explain why 4. z" = Log ( 1 + θ fixed α fixed {i-co-C)-is nC)} fised θ fixed
The given sequence is
\(z_n = log(1 + (θ/(α + {i*cos(π/2) - i*sin(π/2)}))^n)\)
First, we need to simplify the expression inside the log. The term \({i*cos(π/2) - i*sin(π/2)}\) can be simplified to 0, since cos(π/2) = 0 and sin(π/2) = 1.
Therefore, the expression inside the log becomes \((1 + (\theta/\alpha)^n)\).
Now, we need to find the limit of this sequence as n approaches ∞.
If θ/α is less than 1, then (θ/α)^n will approach 0 as n approaches infinity, and the limit of the sequence will be log(1) = 0.
If θ/α is greater than 1, then (θ/α)^n will approach infinity as n approaches infinity, and the limit of the sequence will be log(infinity) = infinity.
If θ/α is equal to 1, then (θ/α)^n will always be 1, and the limit of the sequence will be log(2).
Therefore, the limit of the sequence depends on the values of θ and α. If θ/α < 1, the limit is 0. If θ/α > 1, the limit is infinity. If θ/α = 1, the limit is log(2).

Being a girl and playing a sport are C. No, they are not independent events, because P(girl) 0.49 and P(girl plays a sport) ~ 0.62.
Let's consider the probabilities:
P(girl) = (number of girls) / (total number of students) = 135 / 275 ≈ 0.49
P(girl plays a sport) = (number of girls playing a sport) / (total number of students) = 76 / 275 ≈ 0.276
If being a girl and playing a sport were independent events, the joint probability would be the product of the individual probabilities:
P(girl) × P(girl plays a sport) ≈ 0.49 × 0.276 ≈ 0.13524
However, the actual joint probability is different from the expected value:
P(girl, plays a sport) ≈ 76 / 275 ≈ 0.276
Since the joint probability does not match the product of the individual probabilities, we can conclude that being a girl and playing a sport are not independent events based on the given data.
