(25/4)^3x = 32/3125
Answer:
The solution is [tex]x = -\frac{5}{6}[/tex]
Step-by-step explanation:
We solve this question using exponential properties.
We have that:
[tex](\frac{25}{4})^{3x} = \frac{32}{3125}[/tex]
Simplifying:
[tex](\frac{5^2}{2^2})^{3x} = \frac{2^5}{5^5}[/tex]
[tex]([\frac{5}{2}]^{2})^{3x} = (\frac{2}{5})^{5}[/tex]
[tex](\frac{5}{2})^{6x} = (\frac{2}{5})^{5}[/tex]
Changing the numerator and denominator in the right side:
[tex](\frac{5}{2})^{6x} = (\frac{5}{2})^{-5}[/tex]
Since both bases are equal:
[tex]6x = -5[/tex]
[tex]x = -\frac{5}{6}[/tex]
The solution is [tex]x = -\frac{5}{6}[/tex]

An orange juice manufacturer advertises a new orange juice product that contains 50% less sugar. This new product is expected to increase profits substantially because they create the 50% less sugar product by replacing 50% of the juice with water while selling it for the same price. An inspector wants to investigate whether the actual percentage of water in the product is within 5% of the intended 50%.
He selects a random sample of 500 containers of orange juice and determined the percentage of each that is water. He plans to conduct a significance test at the a = 0.01 level to see if there is convincing evidence that the proportion of water added is different from 0.50. What is the probability that the inspector makes a Type I error?
Answer:
0.01
Step-by-step explanation:
The probability of making a Type I error is equal to \alphaα = 0.01, the significance level of the test
The probability of type 1 error will then be equal to the hypothesis level of significance and this will be 0.01.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
An orange juice manufacturer advertises a new orange juice product that contains 50% less sugar.
An inspector wants to investigate whether the actual percentage of water in the product is within 5% of the intended 50%.
He plans to conduct a significance test at a = 0.01 level to see if there is convincing evidence that the proportion of water added is different from 0.50.
Type I error is referred to as false positives and it means that when a statistically significant difference is validated by the researcher even though the results aren't statistically significant.
Type I error is when one rejects the null hypothesis even though it's true. In this case, the inspector rejects the hypothesis that the proportion of water that is contained in the product is 0.5.
The probability of type 1 error will then be equal to the hypothesis level of significance and this will be 0.01.

Answer: y>-2 (The symbol has a underline)
Step-by-step explanation:
Since you want to move -4 to the -6 spot, do the opposite of the negative which is positive. So add +4 to each side. And the -4 will disappear and you will be left with y>-6+4. Solve -6+4= -2 And so the answer is y>-2.

Two containers hold several balls. Once a second, one of the balls is chosen at random and switched to the other container. After a long time has passed, you record the number of balls in each container every second. In 10,000 s, you find 80 times when all the balls were in one container (either one) and the other container was empty.
Required:
a. How many balls are there?
b. What is the most likely number of balls to be found in one of the containers?
Answer:
(a) 8 balls
(b) 4 balls
Step-by-step explanation:
Let
[tex]N \to[/tex] Number of balls
For a box, the probability that there are N balls in it is:
[tex]Pr = 0.5^N[/tex]
For 2 boxes, it is:
[tex]Pr = 2 * 0.5^N[/tex]
From the question, we have:
[tex]\frac{80}{10000} \to[/tex] Favorable outcome
To solve for N, we have:
[tex]2 * 0.5^N = \frac{80}{10000}[/tex]
[tex]2 * 0.5^N = 0.008[/tex]
Divide both sides by 2
[tex]0.5^N = 0.004[/tex]
Take log of both sides
[tex]\log(0.5^N) = \log(0.004)[/tex]
Apply law of logarithm
[tex]N\log(0.5) = \log(0.004)[/tex]
Make N the subject
[tex]N = \frac{\log(0.004)}{\log(0.5)}[/tex]
[tex]N =7.966[/tex]
Approximate
[tex]N = 8[/tex]
Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:
[tex]Balls \approx \frac{N}{2}[/tex]
[tex]Balls \approx \frac{8}{2}[/tex]
[tex]Balls \approx 4[/tex]
4 balls in each box

Answer:
5. m<A = 25.3°; m<B = 64.7°
6. m<A = 40.2°; m<B = 49.8°
Step-by-step explanation:
Recall: SOHCAHTOA
5. Reference angle = <A
Opposite = 9
Adjacent = 19
Apply TOA:
Tan A = Opp/Adj
Tan A = 9/19
A = Tan^{-1}(9/19)
A = 25.3461759° ≈ 25.3° (nearest tenth)
Reference angle = <B
Opposite = 19
Adjacent = 9
Apply TOA:
Tan B = Opp/Adj
Tan B = 19/9
B = Tan^{-1}(19/9)
B = 64.6538241° ≈ 64.7° (nearest tenth)
6. Reference angle = A
Opposite = 20
Hypotenuse = 31
Apply SOH:
Sin A = Opp/Hyp
Sin A = 20/31
A = sin^{-1}(20/31)
A = 40.2° (nearest tenth)
Reference angle = B
Adjacent = 20
Hypotenuse = 31
Apply CAH:
Cos B = Adj/Hyp
Cos B = 20/31
B = cos^{-1}(20/31)
B = 49.8° (nearest tenth)

A jet skier departs from Pier 1, travels 796 meters directly to a buoy, makes a turn, and travels 1054 meters directly to Pier 2, which is 411 meters from Pier 1.
How many degrees was the jet skier's turn?
Round your answer to the nearest whole degree.
9514 1404 393
Answer:
160°
Step-by-step explanation:
The path is a triangle with side lengths 796, 1054, and 411 meters. The turn is opposite the short side. The interior angle of the triangle at that point can be computed using the law of cosines. If we label the sides a, b, c, respectively, then ...
c² = a² + b² - 2ab·cos(C)
C = arccos((a² +b² -c²)/(2ab)) = arccos(1575611/1677968) ≈ 20.116°
The external angle at the buoy is 180° -20° = 160°.
The jet skier's turn was about 160°.

In the xy-plane, the graph of function f(x) has zeros at −5, −2, and 2. Write the polynomial function.
Answer:
[tex]f(x) = x^3 +5x^2-4x-20[/tex]
Step-by-step explanation:
Given
[tex]Zeros: -5,-2,2[/tex]
Required
The polynomial function
If a function has a, b and c as its zeros, the function is:
[tex]f(x) = (x - a)(x - b)(x - c)[/tex]
So, we have:
[tex]Zeros: -5,-2,2[/tex]
[tex]f(x) = (x - (-5))(x - (-2))(x - 2)[/tex]
Open the inner brackets
[tex]f(x) = (x +5)(x +2)(x - 2)[/tex]
Expand the difference of two squares
[tex]f(x) = (x +5)(x^2 - 4)[/tex]
Expand
[tex]f(x) = x^3 +5x^2-4x-20[/tex]

The average credit card debt for a recent year was $8,776. Five years earlier the average credit card debt was $8,189. Assume sample sizes of 32 were used and the population standard deviations of both samples were $690. Is there evidence to cónclude that the average credit card debt has increased? Use a- 0.05
a. State the hypotheses
b. Find the critical value.
c. Compute the test statistic
d. Make the decision.
e. Summarize the results
Answer:
We reject H₀. We support that the new average credit card debt is bigger than the previous average
Step-by-step explanation:
Five years earlier
μ = 8189
σ = 690
Sample size n = 32
Recent year debt
x = 8776
Sample size n = 32
a) Hypothesis Test:
Null Hypothesis H₀ x = μ = 8189
Alternative Hypothesis Hₐ x > μ
b) z(c) Alternative Hypothesis establishes that the test is a one tail-test to the right.
z(c) for significance level α = 0.05 is from z-table z(c) = 1,64
c) z(s) = ( x - μ ) / σ /√n
z(s) = ( 8776 - 8189 ) / 690 /√32
z(s) = 587 *5,66/ 690
z(s) = 4,81
d) Comparing z(c) and z(s)
z(s) > z(c) Then z(c) is in the rejection region and we reject H₀
e) We have evidence that at 95 % of confidence the new value for the debt in credit card is now bigger than the average

the rectangle shown has an area of 105 square inches. the width is x+ 16 inches and the length is x. find the dimensions of the rectangle
Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
