Solution and answer
Let x be the number that can be multiplied by 3/4 and get 1.
(3/4)*x = 1 Multiiply both sides by 4
4*(3/4)x = 4*1 Combine
3x = 4 Now divide by 3
3x/3 = 4/3
x = 1 1/3 or x = 4/3 or x = 1.3333333

the edges of a cube are expanding at a rate of 5 centimeters per second. how fast is the surface area increasing
The surface area is increasing at the rate of (60 x + 150) cm² per second.
Let the side of the cube be x cm.
s = x cm
Surface area of the cube will be:
S = 6 x² cm²
Now, we are given that, the side of the cube is expanding 5 cm per second.
So, the side of the cube after 1 second will be:
s' = x + 5 cm
Surface area will be:
S' = 6 (x + 5)² cm²
S' = (6x² + 150 + 60 x) cm²
Change in the surface area is:
ΔS = (6x² + 150 + 60 x) cm² - 6 x² cm²
ΔS = (60 x + 150) cm²
Therefore, the surface area is increasing at the rate of (60 x + 150) cm² per second.

If MJ is 25 ft. long and M'J' is 5 feet long, what was the scale factor, k?
The scale factor, if MJ is 25 ft. long and M'J' is 5 feet long is 1/5
If MJ is considered as the original figure, it is 25 ft. long.
The image of MJ, M'J' is 5 feet long
Scale factor is generally understood as the number of times the dimensions of the image is enlarged or diminished
Scale factor = Dimension of the new image ÷ Dimension of the original shape
Scale factor = M'J' length/ MJ length
k = 5/25
k = 1/5
The value of scale factor = 1/5, which means the new image is diminished.
Therefore the scale factor, if MJ is 25 ft. long and M'J' is 5 feet long is 1/5.

The interest rate is approximately 5.23%.
Interest is the amount paid over and above the principal amount to a lender or depositor by a borrower or financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).
It differs from any fees the borrower may be required to pay to the lender or another party. It also contrasts from dividends, which are paid out to shareholders (owners) by a company from its profit or stockpile, but not at a predefined rate but rather on a pro rata basis as a portion of the reward received by risk-taking businesspeople when the revenue obtained exceeds the overall expenses.We know that the amount from an loan is calculated by the formula

Step-by-step explanation:
The graph of y=f(x) is shown on the grid. The graph G is a translation of the graph y=f(x)
The translated function is:
G(x) = f(x) - 1
b) The maximum of y = 2*f(x) is the point (0, 8).
How to write the equation of the translated function?
We know that G(x) is a translation of f(x), and the graph of G(x) is the pink one.
We can see that it is 1 unit below f(x), then we have a translation of one unit downwards, so we can write:
G(x) = f(x) - 1
This is the rule for G(x).
b) If the maximum of f(x) is (0, 4), then:
f(0) = 4
The maximum of 2*f(x) is also at x = 0, we will get:
2*f(0) = 2*4 = 8
So the maximum here is (0, 8).

How to determine the transformation of the graph?The equation of the graph is given as
f(x) = x^2
The above equation a parent equation of a quadratic equation
Using the graph as a guide, we can see that
The function f(x) is translated to the right by 2 units to get g(x)
This means that
g(x) = f(x - 2)
So, we have
g(x) = (x - 2)^2
Hence, the equation of g(x) is g(x) = (x - 2)^2

4) Which one of these pictures is not like the others? Use ratios to explain your reasoning. (From Unit 2, Lesson 1) co ΝΗ e M
We are shown three pictures and asked to identify which one of them is not like others.
Let us find the ratio of width and length of each inscribed cricle.
Picture L:
Width = 3 units
Length = 4 units
Ratio = 3/4 = 0.75
Picture M:
Width = 4 units
Length = 8 units
Ratio = 4/8 = 0.50
Picture N:
Width = 9 units
Length = 12 units
Ratio = 9/12 = 0.75
As you can see, picture L and N has the same ratio of width and length that is 0.75 but the picture M has a different ratio of width and length that is 0.50
Therefore, we can conclude that picture M is not like others.

b) suppose that pearson’s test of goodness of fit will be used to evaluate the claim that half of restaurants go out of business every three years, with a significance level of 0.01.(approximately) what will the chance of a type i error for this test be?
The Pearson's test of goodness fit can be used to check the significance of 0.01 but there would not be any type 1 error.
A statistical test that measures how well sample data matches a distribution from a population with a normal distribution is referred to as goodness-of-fit. Simply put, it hypothesizes if a sample is skewed or represents the data found in the actual population.
The goodness-of-fit test determines the difference between the actual and predicted values of the model in the case of a normal distribution. The chi-square is one of the approaches for determining goodness-of-fit.
Goodness-of-fit testing is a statistical technique used to draw inferences about observed values.
For example, check to see if a sampling group truly represents the entire population. That is, they establish the relationship between measured and predicted values in a model. When used in a decision-making process, goodness-of-fit tests allow you to foresee future trends and patterns.
Hence we can conclude that there would not be any error to the problem with a significance of 0.01 .
