Answer: x=4 hours

Step-by-step explanation:

5 lawns mowed  -  x hours

12 lawns mowed  -  9.6 hours

Hence,

\(\displaystyle\\x=\frac{5*9.6}{12} \\\\x=\frac{48}{12}\\\\x=4\ hours\)

Answer:

The answer is 15.

Step-by-step explanation:

So the problem with this equation, note that the question does not state this which does make it confusing, is that the x is in the wrong place.

So instead of 5/6.25 = x/12

It's actually 5/6.25 = 12/x, entirely changing the problem.

When we cross multiply we'll end up having an equation like this:

5x = 6.25 x 12

6.25 x 12 = 75

75/5 = 15

Therefore our answer is 15.

An essential concept in mathematics and can be applied to a variety of fields such as physics, economics, and engineering.

The slope of a line in a Cartesian plane is a numerical representation of its steepness and inclination relative to the x-axis.

The slope of a straight line refers to the rise or fall of the y-coordinate as it moves from left to right along the x-axis.

There are a few different ways to interpret the slope of a line, but generally it can be thought of as the rate at which the dependent variable changes with respect to the independent variable.
When the slope is positive, the line rises from left to right, indicating that the dependent variable is increasing as the independent variable increases.

In other words, there is a direct relationship between the two variables.

Conversely, when the slope is negative, the line falls from left to right, indicating that the dependent variable is decreasing as the independent variable increases.

This means that there is an inverse relationship between the two variables.
The magnitude of the slope can also provide information about the relationship between the variables.

If the slope is close to zero, then the relationship between the two variables is weak or nonexistent.

However, if the slope is large in magnitude (i.e. close to 1 or -1), then there is a strong relationship between the variables.

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes, while a slope of undefined means that the line is vertical and has no slope.

Answer:  The graph is shown below. It is nonlinear

==========================================================

Explanation:

I used GeoGebra to make the graph. Desmos is another option I recommend.

The equation we graph is y = (1/2)^x since we're splitting the paper in half each time. This is an exponential decay function. Note how the curve slopes downhill when moving to the right.

It appears the curve touches or crosses the x axis; which is misleading. Instead, the curve is getting closer and closer to this horizontal asymptote. It will never reach the x axis. Think of it like an electric fence.

As the graph indicates, we don't have a straight line. Therefore, the function isn't linear. It's a nonlinear curve.

The absolute maximum value is approximately 5.71, and the absolute minimum value is approximately 1.57 for the function f(t) = t + cot(t/2) on the interval [π/4, (7π)/4].

To find the absolute maximum and absolute minimum values of the function f(t) = t + cot(t/2) on the interval [π/4, (7π)/4], we can follow these steps:

Find the critical points of the function by taking the derivative of f(t) and setting it equal to zero.

Evaluate the function at the critical points and the endpoints of the interval.

Compare the values obtained to determine the absolute maximum and absolute minimum.

Let's start by finding the critical points:

Step 1:

Taking the derivative of f(t) with respect to t:

f'(t) = 1 - (1/2)\(cosec^2(t/2)\)

Setting f'(t) equal to zero:

1 - (1/2)\(cosec^2(t/2)\) = 0

Solving for t:

\(cosec^2(t/2)\)  = 2

\(sin^2(t/2)\) = 1/2

sin(t/2) = ±√(1/2)

t/2 = π/4 or t/2 = (3π)/4

t = π/2 or t = (3π)/2

So, the critical points are t = π/2 and t = (3π)/2.

Step 2:

Now, we evaluate the function f(t) at the critical points and the endpoints of the interval:

f(π/4) = (π/4) + cot((π/4)/2) = (π/4) + 1 = 1 + π/4 ≈ 1.79

f((7π)/4) = ((7π)/4) + cot(((7π)/4)/2) = ((7π)/4) - 1 = 7π/4 - 1 ≈ 5.71

f(π/2) = (π/2) + cot((π/2)/2) = (π/2) + 0 = π/2 ≈ 1.57

f((3π)/2) = ((3π)/2) + cot(((3π)/2)/2) = ((3π)/2) + 0 = 3π/2 ≈ 4.71

Step 3:

Comparing the values, we can determine the absolute maximum and absolute minimum:

Absolute maximum: The maximum value is f((7π)/4) ≈ 5.71, which occurs at t = (7π)/4.

Absolute minimum: The minimum value is f(π/2) = 1.57, which occurs at t = π/2.

Therefore, the absolute maximum value is approximately 5.71, and the absolute minimum value is approximately 1.57 for the function f(t) = t + cot(t/2) on the interval [π/4, (7π)/4].

The store should have 445 picks remaining, not 450 as estimated by the manager. To determine if the store manager's estimate is reasonable, let's analyze the situation.

The store initially has 500 guitar picks. They order 15 boxes, and each box contains 9 picks. So the total number of picks they receive from the order is:

15 boxes * 9 picks/box = 135 picks

Next, the store sells 19 boxes, with each box containing 10 picks. Therefore, the total number of picks sold is:

19 boxes * 10 picks/box = 190 picks

To find the remaining number of picks, we can subtract the sold picks from the received picks:

Total remaining picks = Initial picks + Received picks - Sold picks

Total remaining picks = 500 + 135 - 190 = 445 picks

According to the calculations, the store should have 445 picks remaining, not 450 as estimated by the manager.

However, it's important to note that we are working with whole numbers, so there might be some rounding involved in the manager's estimate. It's possible that the manager rounded up to 450 for simplicity or other reasons.

Given the small discrepancy of 5 picks between the calculated value and the manager's estimate, it is reasonable to conclude that the manager's estimate is close enough to the actual number of picks. The discrepancy could be due to rounding or a small counting error. It's unlikely to have a significant impact on the store's operations or inventory management.

In summary, while the manager's estimate of 450 guitar picks may not be exactly accurate, it is reasonably close to the actual remaining number of picks based on the given information.

There will be 12 combination of  different king-queen.

When grouping objects or figuring out how many subgroups can be created from a given collection of objects, combinations are employed. We also employ permutations to calculate the number of possible combinations of unrelated things.

To determine the number of different king-queen combinations, we need to multiply the number of candidates for king by the number of candidates for queen. In this case, there are four candidates for homecoming queen and three candidates for king.

There are 4 candidates for queen and 3 candidates for king, so:

4 x 3 = 12

The equation that represents the inverse of the function t = 35.50 + 0.0625s is t = (s - 35.50) / 0.0625.

The inverse of a function represents the relationship between the input and output variables in reverse.

To find the inverse of the function t = 35.50 + 0.0625s, we need to interchange the roles of the variables t and s.

Step 1: Replace t with s and s with t in the given function:
s = 35.50 + 0.0625t

Step 2: Solve the equation for t to express it in terms of s:
s - 35.50 = 0.0625t
Divide both sides of the equation by 0.0625:
(s - 35.50) / 0.0625 = t

Step 3: Simplify the equation:
t = (s - 35.50) / 0.0625

Therefore, the equation that represents the inverse of the function t = 35.50 + 0.0625s is t = (s - 35.50) / 0.0625.

Answer:

She earns 5.5 dollars per hour at the library

Step-by-step explanation:

I am going to assume that the questions is "how much she earns per hour at the library?"

Let's call x the amount of dollars earn by hour at the library. We know that she worked for 6 hours, thus she made 6x dollars.

Later her grandma gave her 20 dollars and she has now 53 dollars.

Let's write the equation and solve it

Amount earned + Amount given by her grandma = 53

\(6x+20=53\\6x=33\\x=\frac{33}{6}\\x=5.5\)

Thus, based on this information we would have that Kia earns 5.5 dollars per hour.

The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is given by: Option B: 0.284 approx.

Suppose two dimensions are there, viz X and Y. Some values of X are there as \(X_1, X_2, ... , X_n\) and some values of Y are there as \(Y_1, Y_2, ... , Y_n\)

List them in title of the rows and left to the columns. There will be \(n \times k\) table of values will be formed(excluding titles and totals), such that:

Value(ith row, jth column) = Frequency for intersection of  \(X_i\)  and \(Y_j\)  (assuming X values are going in rows, and Y values are listed in columns).

Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.

For n = 2, and k = 2, the table would look like:

\(\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}\)

where S denotes total of totals, also called total frequency.

n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

\(P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}\)

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

The missing frequency table is attached below. If we name events as:

Then, the needed probability is P(B|A) (as it is already specified that the person would be older than 35 years.)

Using the table, we get:

\(P(A) = \dfrac{\text{Total person who are older than 35 years age}}{\text{Total person in survey}}\\\\P(A) = \dfrac{162}{429} \approx 0.3776\)

Using the table, we get the value on the place where A and B both occur(when person selected is older than 35 years and have hemoglobin between 9 and 11 ) as:

\(n(A \cap B) = 162 - 40 - 76 = 46\)

Thus, we get:

\(\\\\P(A\cap B) = \dfrac{\text{Total person older than 35 years age and have hemoglobin level between 9 and 11}}{\text{Total person in survey}}\\\\P(A \cap B) = \dfrac{46}{429} \approx 0.1072\)

Using the chain rule, we get:

\(P(B|A)P(A) = P(A\cap B)\\\\P(B|A) = \dfrac{P(A \cap B)}{P(A)} = \dfrac{0.1072}{0.3776} \approx 0.284\)

Thus, the probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is given by: Option B: 0.284 approx.

The type of scale used to evaluate the food at a new restaurant on 7-point scales with bipolar adjectives such as good-bad and inexpensive-expensive is known as a Likert scale.

This type of scale is commonly used in surveys to measure attitudes and opinions towards a particular topic, in this case, the food at a new restaurant. A Likert scale consists of a series of statements or adjectives that respondents are asked to rate on a scale that ranges from strongly disagree to strongly agree or, in this case, from bad to good and from inexpensive to expensive.

The bipolar adjectives used in the scale allow for a clear distinction between the positive and negative aspects of the food, which helps to ensure that the responses are more accurate and meaningful. The 7-point scale provides a wider range of options than a binary scale, which allows for more nuanced and detailed responses.

∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements from the given information

Two angles are given.

∠g = (2x-90)°

∠h = (180-2x)°

We have to find the statement which is true about the angles g and h.

If both angles are greater than zero.

Complementary angles add up to 90 degrees

i.e., ∠g and ∠h are complementary if ∠g + ∠h = 90°.

Substituting the given values:

∠g + ∠h

= (2x-90)° + (180-2x)° = 90°

Thus, ∠g and ∠h are complementary angles.

and both the angles are less than 90 degrees so we can tell that angles ∠g and ∠h  are acute.

So the statement ∠g and ∠h are acute angles is also true
