Answer:
d is greater than c, since at [tex]x = 0, g(x) > f(x)[/tex]
Step-by-step explanation:
We are given two exponential functions, f(x) and g(x).
Since f has the higher base(3 instead of 2 in g), it increases faster, so initially, g is greater than f, and after point (p,q), f is greater than g.
The values of c and d are found when [tex]x = 0[/tex]. At this point, we have that function g is greater than function f, which means that d is greater than c.
In planning her retirement, Liza deposits some money at 4% interest, with twice as much deposited at 4.5%. Find the amount deposited at each rate if the total annual interest income is $2080.
She deposited $___ at 4% and $____ at 4.5%.
She deposited $16,000 at 4% and $32,000 at 4.5%
She deposited $16,000 at 4% and $32,000 at 4.5%.
Let's assume Liza deposited an amount x at 4% interest. According to the given information, she deposited twice as much, which is 2x, at 4.5% interest.
To calculate the interest income from the deposits, we'll use the formula: Interest = Principal × Rate × Time.
At 4% interest, the interest earned is 0.04x (4% expressed as a decimal multiplied by x).
At 4.5% interest, the interest earned is 0.045(2x) (4.5% expressed as a decimal multiplied by 2x).
We know that the total annual interest income is $2080. Therefore, we can write the equation:
0.04x + 0.045(2x) = 2080
Simplifying the equation:
0.04x + 0.09x = 2080
0.13x = 2080
x = 2080 / 0.13
x ≈ 16,000
Liza deposited approximately $16,000 at 4% interest, and since she deposited twice as much at 4.5% interest, she deposited approximately $32,000 at 4.5% interest.
Therefore, she deposited $16,000 at 4% and $32,000 at 4.5%.

A state's Department of Education reports that 12% of the high school students in that state attend private high schools. The State University wonders if the percentage is the same in their applicant pool. Admissions officers plan to check a random sample of the over 10,000 applications on file to estimate the percentage of students applying for admission who attend private schools.
a) They select a random sample of 500 applications, and find that 46 of those students attend private schools. Check the conditions required for inference. (3 marks)
b) Create the 90% confidence interval. (6 marks)
c) Interpret the confidence interval in the context of the problem. (3 marks)
d) Should the admissions officers conclude that the percentage of private school students in their applicant pool is lower than the statewide enrollment rate of 12%? Explain. (2 marks)
Answer:
a) p*n = 46 and q*n = 454 data is enough for inference
b) CI = ( 0,099 ; 0,141)
c) CI we will find with 90% of confidence the value of p in that interval
d) No, we accept H₀ we don´t have evidence to claim that the percentage in the State University is smaller than that of the Department of Education
Step-by-step explanation:
Information from A state´s Department of Education is:
p₀ = 12 % p₀ = 0,12
The State University sample:
Sample size n = 500
Sample proportion 46 out of 500
p = 46/500 p = 0,092 then q = 1- p q = 1 - 0,092 q = 0,908
Both p*n = 46 and q*n = 454
a) Are big enough to approximate the binomial distribution to normal distribution
b) CI = 90% CI = 0,9 significance level α = 0,10 for an CI we need
α/2 = 0,10/2 α/2 = 0,05
z(c) = - 1,64 ( from z-table)
MOE = z(c)*√(p*q)/n
MOE = 1,64 * √ ( 0,092*0,908)/500
MOE = 1,64 *√0,08353/500
MOE = 1,64 * 0,0129
MOE = 0,021
Then CI = 90 % is:
CI = ( 0,12 - 0,021 < P < 0,12 + 0,021 )
CI = ( 0,099 ; 0,141)
We have with 90 % of confidence for finding the value of p in the interval
Test Hypothesis
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p < p₀
we have for α = 0,1 z(c) = - 2,32 from z table
And z(s) = ( p - p₀ ) / √ (p*q)/n
z(s) = ( 0,092 - 0,12 ) / √(0,092*0,908)/500
z(s) = - 0,028 / 0,0129
z(s) = - 2,17
Comparing z(s) and z(c) we see that
|z(s)| < |z(c)|
So z(s) is in the acceptance region. We can support the claim that the percentage in the State University is the same than that of the Departament of Education

Answer:
15 cups
Step-by-step explanation:
The formula to find cups from quarts C = Q * 4, where c is how many cups, and Q how many quarts. To find how many cups are in a quart, simply multiply the number of quarts by 5. In this case, there are 3 3/4 quarts of coffee, multiply that by 5, and you would get 15 cups of coffee!

Answer:
n = 20
Step-by-step explanation:
Since the triangles are similar, we can create a common proportion.
[tex]\frac{15}{12} =\frac{n}{16}[/tex]
Now you have to solve this proportion
Start by cross multiplying, and you get 12n = 240
Divide both sides by 12, and you get n = 20.
Hope this helped
Hey there!
The answer to your question is n = 20
Since they are similar, we can use proportions:
12/15 = 16/n
Then we can use cross products:
15 x 16 = 12n
140 = 12n
20 = n

Warren is on vacation and needs to arrange transportation. A rental car costs 60 dollars per day plus a one-time cost of 14 dollars for insurance. Construct a function C(x) that gives the total cost of renting a car for x days.
C(x) = ______________
If Warren has budgeted 434 dollars for the rental, how many days can he afford?
Answer:
The answer is C(x) = 60x + 14 and the answer to the second one is 7 days.
Step-by-step explanation:
C(x) =60x + 14
434 = 60x + 14
-14 -14
420 = 60x
/60 /60
7 = x
or
x = 7 days
Find the slope of the line. The slope of the line is
Answer: The slope of the line is [tex]\frac{3}{4}.[/tex]
Step-by-step explanation: I use the slope formula to find the slope of the line given the graph image below that looks like this:[tex]\frac{Rise}{Run}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}.[/tex]
The rise of the points is 3 points and the run of the points is 4 points.
Now I can put it in another slope formula that looks like this: [tex]\frac{3-0}{2-(-2)}=\frac{3}{4}.[/tex]
I hoped my answer was found very helpful to your own question and have more understanding and happy Halloween! :D

The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1). Name the vertices of P'Q'R' after a reflection over the x-axis.
Answer:
The coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)
Step-by-step explanation:
We are given:
The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1).
We need to:
Name the vertices of P'Q'R' after a reflection over the x-axis.
Reflection over the x-axis
The rule used for reflection over x-axis
P(x,y)= P'(x,-y)
The coordinates of x-axis remains same, while coordinates of y-axis become negative.
Now, finding coordinates of P'Q'R'
P (2,-8) -> P' (2,8)
Q(1,-4) -> Q' (1,4)
R(4,-1) -> R'(4,1)
So, the coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)

Answer:
Step-by-step explanation:
you have a pentagon , and the sum of the angles is 540
3x-10+3x-8+5x-2+3x+1+2x+15=16x-4=540
16x-4=540
16x=544
x=544/16=34
the angle= (3x-8)=(3*34)-8=94
