Drag the expressions to the boxes to order them from least to greatest. 7/7 × 4/9 3/4 × 4/9 1 2/3 × 4/9 2 × 4/9
Least to greatest
The correct order from least to greatest is 3/4 × 4/9, 7/7 × 4/9, 2 × 4/9, 1 2/3 × 4/9.
To order the expressions from least to greatest, we need to compare their values. Let's evaluate each expression:
7/7 × 4/9 = 1 × 4/9 = 4/9
3/4 × 4/9 = 3 × 4/36 = 12/36 = 1/3
1 2/3 × 4/9 = (5/3) × 4/9 = 20/27
2 × 4/9 = 8/9
Now, let's arrange the expressions from least to greatest:
1/3 < 4/9 < 8/9 < 20/27
Therefore, the correct order from least to greatest is:

A study of a population of 1,200 frogs revealed that 12 out of every 180 frogs in the population have spots on their back. Based on the results of this study, how many frogs do not have spots on their back? Explain.
Answer:
80 spotted frogs
Step-by-step explanation:
We can write a ratio
spotted frogs:frogs
12:180
x:1200
To solve we just multiply 12*6.66667 (because this is what we multiplied 180 to get to 1200)

Wally's average speed in miles per hour 1 1/15 miles per hour.
What was Jada and Kiran’s average speed?Speed is the rate at which an object's location changes in a particular direction. The distance traveled in relation changes to a particular direction. The distance in relation to the time it took to travel the distance is the speed. It's a scalar quantity.
In this case, Wally, a tortoise traveled 4/5 of a mile in 3/4 of an hour.
Jada and Kiran’s average speed will be:
Speed = Distance / Time
Speed = 4/5 ÷ 3/4

On a recent math test, a student wrote that (x + 4)^2 = (x^2 + 16). Are they correct? Provide reasons for your answer
Answer:
No
(x + 4) ^2 = (x^2 + 8x + 16)
Step-by-step explanation:
You have to factor the equation (X + 4) ^2.
Expanded: (x + 4) * (x + 4)
Using the foil technique:
First: (x) * (x) = x^2
Outer: (x) * (4) = 4x
Inner: (4) * (x) = 4x
Last: (4) * (4) = 16
Factor equations should look like this
a^2 + bx + c, where the Outer and Inner values are added together. Resulting in:
x^2 + 8x + 16
The perimeter of a rectangle is 160 feet. If the length of the rectangle is 28 feet more than the width, what are the dimensions of the rectangle?
Answer:
width = 26 ft
length = 54 ft
Step-by-step explanation:
perimeter = 160 ft
width = x
length = x + 28
Perimeter = 2(width) + 2(length)
\(2x + 2(x + 28) = 160 \\ 2x + 2x + 56 = 16 0\\ 4x = 160 - 56 \\ x = \frac{104}{4} \\ x = 26\)
width = x = 26
length = x + 28 = 26 + 28 = 54

You want to calculate the area of your dorm room which is in a rectangular shape. You measure the length and the width of the room as =5.2±0.1 m,L=5.2±0.1 m, W=4.5±0.1 m.W=4.5±0.1 m. What is the absolute error in the area in m2 units?
To calculate the absolute error in the area of a dorm room with length L = 5.2 ± 0.1 m and width W = 4.5 ± 0.1 m, we need to determine the maximum possible difference in the area caused by the uncertainties in the measurements.
The area A of the dorm room is given by the formula A = L × W. To calculate the absolute error in the area, we consider the uncertainties in the length and width measurements.
The maximum possible length is L + δL, and the minimum possible length is L - δL, where δL represents the uncertainty in the length measurement. Similarly, the maximum possible width is W + δW, and the minimum possible width is W - δW, where δW represents the uncertainty in the width measurement.
Therefore, the maximum possible area is (L + δL) × (W + δW), and the minimum possible area is (L - δL) × (W - δW). The absolute error in the area is the difference between the maximum and minimum areas:
Absolute error = (L + δL) × (W + δW) - (L - δL) × (W - δW).
Simplifying this expression, we get:
Absolute error = 4δLW + LδW + δLW.
Given the values of δL = 0.1 m and δW = 0.1 m, we can substitute them into the formula to calculate the absolute error in the area in m^2 units.

How large must be a test statistic to reject the null hypothesis in favor of alternative hypothesis?
To determine how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis, we need to first establish a hypothesis test. A hypothesis test is a statistical procedure that helps us determine if there is enough evidence to support a particular hypothesis.
In a hypothesis test, we start with a null hypothesis (H0) which is a statement that there is no significant difference between two groups or variables. The alternative hypothesis (Ha) is the statement that there is a significant difference between the two groups or variables.
Once we have established our null and alternative hypotheses, we need to conduct a statistical test to determine if there is enough evidence to reject the null hypothesis in favor of the alternative hypothesis. The test statistic is the numerical value that we obtain from our statistical test, which we compare to a critical value to determine if we can reject the null hypothesis.
The critical value is determined by the level of significance (α) we have chosen for our test, which is the probability of making a type I error (rejecting the null hypothesis when it is actually true). Typically, the level of significance is set at 0.05 or 0.01.
So, to answer the question, how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis depends on the level of significance we have chosen, as well as the degrees of freedom and distribution of the test statistic. The critical value for a given level of significance and degrees of freedom can be found in statistical tables or calculated using software. If the test statistic is larger than the critical value, we can reject the null hypothesis in favor of the alternative hypothesis.

Question 10.... 9 points Let u and v be non-zero vectors in R"" that are NOT orthogonal, and let A = uvT (a) (3 points) What is the rank of A? Explain. (b) (3 points) Is 0 an eigenvalue of A? Explain.
"
Therefore, a Rank of A = 1.0 is not an eigenvalue of A.
(a) The rank of A = uvT is one. We can see this by the following argument. First, observe that the rank of any matrix is less than or equal to the smaller of its two dimensions. In this case, A is an m × n matrix where
m = dim(u) and n = dim(v),
so rank(A) ≤ min{m, n}.
Because u and v are non-zero and not orthogonal, we know that both dim(u) and dim(v) are at least 1. Thus, the smallest possible value for min{m, n} is 1, and we know that rank
(A) ≤ 1.
On the other hand, it is easy to verify that the vector uvT is not the zero vector, so the columns of A are linearly dependent. This implies that rank(A) cannot be zero and therefore must be 1.
(b) The matrix
A = uvT
has 0 as an eigenvalue if and only if its determinant is zero. To compute the determinant of A, we can use the formula det
(A) = u · (v × u),
where · denotes the dot product and × denotes the cross product. Expanding this expression, we have det
(A) = u1v2u3 − u1v3u2 − u2v1u3 + u2v3u1 + u3v1u2 − u3v2u1.
Because u and v are not orthogonal, we know that at least one of the terms in this expression is non-zero. Therefore, det(A) is non-zero and 0 is not an eigenvalue of A.
Therefore, a Rank of A = 1.0 is not an eigenvalue of A.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, the test, which is worth 100 points, has 35 problems.
Let x = the number of questions worth 5 points.
Let y = the number of questions worth 2 points.
Now, x+y=35 ---------(I)
Each problem is worth either 5 points or 2 points.
5x+2y=100 ---------(II)
From equation (I), we have x=35-y
Substitute, x=35-y in equation (II), we get
5(35-y)+2y=100
175-5y+2y=100
3y=75
y=25
Substitute y=25 in equation (I), we get
x+y=35
x=10
Therefore, the number of questions worth 5 points are 10 and the number of questions worth 2 points are 25.
