Ms. Wilson invested $30,000 in two accounts, one yielding 8% interest and the
other yielding 9%. If she received a total of $2,590 in interest at the end of the
year, how much did she invest in each account?
The amount invested at 8% was $
The amount invested at 9% was $
Answer:
The amount invested at 8% was $11,000
The amount invested at 9% was $19,000
Step-by-step explanation:
Let the variable x represent the amount in $ invested at 8% and let y be the amount in $ invested at 9%
Total amount invested:
x + y = 30000 [1]
8% = 8/100 = 0.08
9% = 9/100 = 0.09
Interest at 8% on $x = 0.08x
Interest at 9% on $x = 0.09x
Total Interest :
0.08x + 0.09y = 2590 [2]
Using equations [1] and [2] we can solve for x and y
We have
x + y = 30000 [1]
0.08x + 0.09y = 2590 [2]
Multiply equation 1 by 0.08 to get
0.08x + 0.08y = 0.08(30,000)
0.08x + 0.08y = 2,400 [3]
Subtract [3] from [2] :
0.08x + 0.09y = 2590
-
0.08x + 0.08y = 2400
----------------------------------
0x + 0.01y = 190
Divide both sides by 0.01
0.01y/0.01 = 190/0.01
y = = 19,000
Use [1] to get value of x
x + y = 30,000
x + 19,000 = 30,000
x = 30,000 - 19,000
x = 11,000

This is obvious that if Rachel only went 9 miles in 1 hour, and Amos traveled 12 miles in 1 hour, and we need to find out how far apart they will be, we can create the equation of:
12 - 9 = 3, meaning they will be 3 miles apart after one hour.
For an explanation, if you look closely, this is extremely easy. It actually tells you how far they go in one hour, as MPH stands for Miles Per Hour. It tells you that Rachel travels 9 hours in an hour and Amos travels 12 hours in an hour. They left at the same exact time from the same point... so you just need to calculate the difference between 12 and 9, which is 3!
Answer:
They are 15 miles apart.
Step-by-step explanation:
We can use the Pythagorean theorem.
The distance up is 12.
And the distance right and left is 9.
Using a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse,
9^2 + 12 ^2 = c^2
81+144 = c^2
225= c^2
Taking the square root of each side,
sqrt(225) = sqrt(c^2)
15 = c
They are 15 miles apart.

At a supermarket, Max buys a shoe worth $\$45$, a $\$66$ jacket, and a $\$175$ DVD player. The cashier scans the shoe, the DVD player, and then the jacket, but Max insists that he would save money if the cashier scanned the more expensive items first. The cashier reluctantly does so, thus first scanning the DVD player, then the jacket, and finally the shoe. How many dollars does Max save by having the cashier follow his way
In both scenarios, the total cost remains the same at $286.
Therefore, Max doesn't actually save any money by changing the scanning order.
Here, we have to calculate how much money Max saves by having the cashier scan the more expensive items first, we need to compare the two scenarios:
the original scanning order and the modified scanning order suggested by Max.
Original Scanning Order:
Shoe ($45) -> Jacket ($66) -> DVD player ($175)
Total cost = $45 + $66 + $175
= $286
Modified Scanning Order:
DVD player ($175) -> Jacket ($66) -> Shoe ($45)
Total cost = $175 + $66 + $45
= $286
In both scenarios, the total cost remains the same at $286.
Therefore, Max doesn't actually save any money by changing the scanning order.
The total amount paid remains unchanged regardless of the order in which the items are scanned.

\( PQ=4\sqrt{2} \:cm=5.66 \: cm\)
Area of square PQRS\( = 32\: cm^2 \)
Step-by-step explanation:
ABCD is a square. Points P, Q, R and S are the midpoints of sides AB, BC, CD and DA of square ABCD respectively.
Therefore,
BP = 1/2 * AB = 1/2 *8 = 4 cm
BQ = 1/2 * BC = 1/2 *8 = 4 cm
In \( \triangle PBQ, \: m\angle PBQ =90\degree \)
Therefore, by Pythagoras theorem:
\( PQ=\sqrt{4^2 +4^2} \)
\( PQ=\sqrt{2*4^2} \)
\( PQ=4\sqrt{2} \:cm=5.66 \: cm\)
Area of square PQRS\( =PQ^2 \)
Area of square PQRS\( =(4\sqrt{2}) ^2 \)
Area of square PQRS\( = 32\: cm^2 \)

Probability of Type 1 0.5 Points For a particular type of hypothesis test with a sample size of 120, a=0.05 and B=0.68. Find the probability of a Type I error. Write your answer as a decimal value with a leading zero. (Don't put any text or supporting work! Just the numeric value.)
The probability of a Type I error is equal to the significance level, which is given as a=0.05 so the probability of a Type I error is 0.05.
The probability of a Type I error is the probability of rejecting a null hypothesis when it is actually true. In other words, it is the probability of concluding that there is a significant effect or difference when in reality there is none.
This probability is denoted by alpha (α) and is usually set at a predetermined level, such as 0.05 or 0.01. In this question, the sample size is 120, and the probability of a Type II error (B) is given as 0.68. To find the probability of a Type I error, we need to subtract the probability of a Type II error from 1 and divide the result by 2. Therefore, the probability of a Type I error is (1 - 0.68) / 2 = 0.16.

We have,
To find f(g) and g(f), we need to perform the composition of functions.
Given:
f = {(-9, -1), (-1, 0), (3, 4)}
g = {(0, -9), (-1, 3), (4, -1)}
To find f(g), we substitute the x-values of g into f:
f(g(0)) = f(-9) = -1
f(g(-1)) = f(3) = 4
f(g(4)) = f(-1) = 0
So, f(g) = {(-9, -1), (3, 4), (4, 0)}
To find g(f), we substitute the x-values of f into g:
g(f(-9)) = g(-1) = 3
g(f(-1)) = g(0) = -9
g(f(3)) = g(4) = -1
So, g(f) = {(-9, 3), (-1, -9), (4, -1)}
Therefore,

assume that the wavelengths of photosynthetically active radiations (par) are uniformly distributed at integer nanometers in the red spectrum from 675 to 700 nm. a. what are the mean and variance of the wavelength distribution for this radiation? b. if the wavelengths are uniformly distributed at integer nanometers from 75 to 100 nanometers, how do the mean and variance of the waveleng
To understand why the mean and variance of the wavelength distribution are the same for different ranges, it is useful to consider the individual wavelengths within the range. A uniform distribution of wavelengths implies that each wavelength within the range has an equal probability of being observed. This means that, regardless of the range, each wavelength has the same probability of being observed. Thus, the mean and variance of the wavelength distribution are the same for different ranges.
A. The mean wavelength of photosynthetically active radiation (PAR) in the red spectrum from 675 to 700 nm is (675 + 700)/2 = 687.5 nm. The variance of the wavelength distribution for this radiation is [(700-675)2]/12 = 5.21 nm2.
B. The mean wavelength of PAR in the range of 75 to 100 nm is (75 + 100)/2 = 87.5 nm. The variance of the wavelength distribution in this range is [(100-75)2]/12 = 5.21 nm2.

Hey guys, need help here
Assuming \(a\) is a non-negative real number...
Raise both sides to the power 2 :
\(a^{3/4} = 8 \implies \left(a^{3/4}\right)^2 = 8^2 \implies a^{3/2} = 64\)
which follows from the exponent product property, \((x^y)^z=x^{yz}\). In particular, 3/4 × 2 = 6/4 = 3/2.
Raise both sides to the power 1/3 :
\(\left(a^{3/2}\right)^{1/3} = 64^{1/3} \implies a^{1/2} = 4\)
where we use the same property as before, and 4³ = 64. This time, 3/2 × 1/3 = 3/6 = 1/2.
Take the reciprocal of both sides. This negates the exponent, so we end up with
\(\dfrac1{a^{1/2}} = \dfrac14 \implies \boxed{a^{-1/2} = \dfrac14}\)
Of course, you could also solve for \(a\) immediately by raising both sides of the original equation to the power 4/3. We have 4/3 × 3/4 = 12/12 = 1, so
\(a^{3/4} = 8 \implies \left(a^{3/4}\right)^{4/3} = 8^{4/3} \implies a = 8^{4/3}\)
Now 2³ = 8, so \(8^{4/3} = \left(8^{1/3}\right)^4 = 2^4 = 16\), and since 4² = 16, it follows that
\(a = 16 \implies a^{1/2} = \sqrt{16} = 4 \implies a^{-1/2} = \dfrac14\)

Answer:
red = 28 apples
green = 13 apples
equations:
r + g = 41
r = g + 15
Step-by-step explanation:
r = number of red
g = number of green
r = g + 15 (the number of red apples is 15 more than the number of green apples)
r + g = 41
Substitute the firs equation into the second and solve for a numerical value of g
(g + 15) + g = 41
2g + 15 = 41
2g = 26
g = 13
Now solve for a numerical value of r
r = g + 15
r = 13 + 15
r = 28
