Answer:
4.5%
Step-by-step explanation:
compound interest formula:
[tex]PV(1+\frac{i}{n})^{t*n}[/tex]
[tex]220=160(1+\frac{x}{365})^{365*7}\\\\1.375=(1+\frac{x}{365})^{2555}\\1.0001246=1+\frac{x}{365}\\x=.0454962254126[/tex]
this rounds to
x=4.5%
Aubrey would need an interest rate of 6.3%.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
A = P [tex](1 + r/n)^{nt}[/tex]
A = the final amount (in this case, $220)
P = the initial investment (in this case, $160)
r = the interest rate (what we are trying to find)
n = the number of times the interest is compounded per year (since it's compounded daily, n = 365)
t = the time period (in years, in this case, 7)
Substituting in the given values and solving for r:
220 = 160(1 + r/365)^(3657)
220/160 = (1 + r/365)^(3657)
1.375 = (1 + r/365)^2555
ln(1.375) = 2555 ln(1 + r/365)
ln(1 + r/365) = ln(1.375)/2555
1 + r/365 = e^(ln(1.375)/2555)
r/365 = e^(ln(1.375)/2555) - 1
r = 365(e^(ln(1.375)/2555) - 1)
r ≈ 6.3%
Therefore,
Aubrey would need an interest rate of 6.3%.

Classify the hypothesis test as two-tailed, left-tailed, or right-tailed.
At one school, the average amount of time that tenth-graders spend watching television each week is hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased from the previous mean of 21.6 hours.
a. Two-tailed
b. Right-tailed
c. Left-tailed
Answer:
C: left tailed
Step-by-step explanation:
In two tailed hypothesis, the alternative hypothesis is when mean can either be lesser or greater than the given value. Usually uses the symbol ≠.
In right tailed, the alternative hypothesis is when the mean is greater than the given value.
In left tailed, the alternative hypothesis is when the mean is lesser than the given value.
In this question, the hypothesis test to be performed is to determine if the average amount of time spent watching television per week has decreased from the given value of 21.6 hours.
Thus, it is left tailed test.

The equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-
Step-by-step explanation:
According to the statement, we have a second order polynomial of the form [tex]A\cdot x^{2}+ B\cdot x + C = 0[/tex], whose solutions can be found by Quadratic Formula:
[tex]x_{1,2} = \frac{-B\pm \sqrt{B^{2}-4\cdot A\cdot C}}{2\cdot A}[/tex] (1)
Where [tex]A[/tex], [tex]B[/tex] and [tex]C[/tex] are the coefficients of the polynomial.
If roots are conjugated complex numbers, then:
[tex]B^{2}-4\cdot A\cdot C < 0[/tex] (2)
[tex]B^{2} < 4\cdot A \cdot C[/tex]
If we know that [tex]A = 1[/tex], [tex]C = 2[/tex] and [tex]x_{1,2} = -1\pm i[/tex], then we find that:
[tex]-1\pm i = -\frac{B}{2}\pm \frac{\sqrt{B^{2}-8}}{2}[/tex]
[tex]-2 \pm i\,2 = -B \pm \sqrt{B^{2}-8}[/tex]
By comparing each side, we have the following system of equations:
[tex]-B = -2[/tex] (3)
[tex]\sqrt{B^{2}-8} = 2[/tex] (4)
Whose solution is [tex]B = 2[/tex].
In a nutshell, the equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-

[tex] \displaystyle \: x_{ \text{lesser}}= - 18.16\\ x _{ \text{greater}} = - 11.84[/tex]
Step-by-step explanation:
we are given a equation
we want to figure out x
add 10 to both sides:
[tex] \displaystyle \: (x + 15 {)}^{2} = 10[/tex]
square root both sides:
remember that,
[tex] \displaystyle \: a = \pm \sqrt{b} [/tex]
by that
[tex] \displaystyle \: x + 15 = \pm\sqrt{10} [/tex]
cancel 15 from both sides:
[tex] \displaystyle \: x = \pm\sqrt{10} - 15[/tex]
