A manager at a shopping mall counts 244 males and n females as they enter the mall. The manager realizes that 25% of all males and 25% of all females are children. She writes the expression 0.25n + 61 to represent the number of children who enter the mall. Is the manager correct?
A.The manager is not correct because there are more than 61 males at the mall.

B.The manager is not correct because the number of children, 0.25(n + 244), is not equivalent to the manager's expression, 0.25n + 61.

C.The manager is correct because the total number of children at the mall is 183.

D.The manager is correct because the number of children, 0.25(n + 244), is equivalent to the manager's expression, 0.25n + 61.

Answer:

the answer is 13

Step-by-step explanation:

Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

What is a linear equation?

A linear equation is an algebraic equation that represents a straight line on a graph. In general, a linear equation takes the form:

y = mx + b

A linear relationship between two variables, x and y, is one in which the change in y is directly proportional to the change in x. This means that for any change in x, there is a corresponding change in y that can be expressed as a constant multiple of x.

For example, if we have a linear relationship y = mx + b, where m is the slope of the line and b is the y-intercept, then if we increase x by 1 unit, y will increase by m units. This relationship holds true for all values of x and y along the line.

A proportional relationship, on the other hand, is a special case of a linear relationship in which the ratio of y to x is always the same constant. This means that if we increase x by 1 unit, y will increase by a constant multiple of x. In other words, the relationship between x and y is one of scaling, where the size of y is always a fixed multiple of the size of x.

Therefore, Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

Answer:

f = 3.74

Step-by-step explanation:

f sin 42° = 2.5

f = 2.5 (sin 42° = 0.669)

sin 41°

= 3.736

= 3.74 (2.d.p.)

The value of f in the given equation is 3.74.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

f sin 42° = 2.5

Dividing both sides of the equation by sin 42°,

f = 2.5 / sin 42°

f = 3.74

Hence the value of f is 3.74.

x=8√3

2). x²=200+81

x=√281

3). x²=169+36

x=√205

3).

Step-by-step explanation:

here's your solution

==> in figure 1,

= perpendicular^2 = hypotenuse^2 - base^2

= x^2 = 16^2 - 8^2

= x^2 = 256 - 64

= x^2 = 192

= x = √192

= x = 13.85

==> in figure 2,

= hypotenuse^2 = Perpendicular^2 + base^2

= x^2 = 40^2 + 9^2

= x^2 = 1600 + 81

= x^2 = 1681

= x = √1681

The maximum amount the money supply can increase is $66.7 million.

To calculate the maximum amount the money supply can increase, we need to consider the concept of the money multiplier. The money multiplier represents the factor by which an initial change in reserves can increase the money supply through the lending and deposit creation process.

In this case, the required reserve ratio is 5%, meaning that banks are required to hold 5% of their deposits as reserves. The remaining portion, which is 95%, can be used for lending and creating new deposits.

Additionally, banks hold excess reserves of 10%, which means that they choose to hold an additional 10% of their deposits as reserves beyond the required amount.

To calculate the money multiplier, we can use the formula:

Money Multiplier = 1 / (Required Reserve Ratio + Excess Reserves Ratio)

In this case, the required reserve ratio is 5% (0.05) and the excess reserves ratio is 10% (0.10).

Money Multiplier = 1 / (0.05 + 0.10) = 1 / 0.15 = 6.67

The money multiplier tells us that for every dollar of reserves, the money supply can potentially increase by $6.67.

Since the Federal Reserve buys $10.00 million in Treasury securities, we can multiply this amount by the money multiplier to determine the maximum potential increase in the money supply:

Maximum Increase in Money Supply = $10.00 million * 6.67 = $66.7 million

\( \displaystyle PW = \underline{ \quad18 \quad}\)

Step-by-step explanation:

by tangent property we acquire:

\( \displaystyle 3x - 6 = x + 10\)

add 6 to both sides:

\( \displaystyle 3x= x + 16\)

cancel x from both sides:

\( \displaystyle 2x= 16\)

divide both sides by 2:

\( \displaystyle x= 8\)

so,

\( \displaystyle PW = 3x - 6\)

plug in the got value of x:

\( \displaystyle PW = 3.8 - 6\)

simplify multiplication:

\( \displaystyle PW = 24- 6\)

simplify Substraction:

\( \displaystyle PW =18\)

hence, The measure of PW is 18 unit

Explanation:

We have the input x = 3 map to the outputs y = 2 and y = 8 at the same time. A function is only possible if any given x value goes to exactly one y value.

Put another way, if x repeats itself, then we don't have a function. This assumes we don't repeat the same y value when we repeat the x value.

Step-by-step explanation:

The picture is a regular hexagonal which means it has six sides of equal length. The triangle in the hexagons are equilateral triangle. This means they have equal length. The blue portion is just like half the area of the hexagon while the white part is also half the area . Note both colors cover 3 triangle each.

area of the hexagon = 3/2 × √3 × a²

where

a = sides

area of the hexagon = 3/2 × √3 × a²

a = 5 ft

convert ft to yard

3 ft = 1 yard

5 ft = 5/3 = 1.6666666667 yards

area = 3/2 × √3 × 1.6666666667²

area of the hexagon = 7.21687836516 yard²

Half of the area is the blue section area because 3 triangle makes half of the hexagon = 7.21687836516/2 = 3.60843918258  yard². Note we can only order whole number of square fabric . Therefore, 3.60843918258 ≈ 4

blue fabric cost $3.50 per square yard.

The cost for this yard = 4  × 3.50 = $14  

white fabric cost $2 per square yard .

The cost for this yard = 4  × 2 = $8

Total cost = 14  + 8  = $22

cost of the fabric = $22

Coefficient estimates from WLS (weighted least squares) are interpreted in a similar manner to those from an un-weighted, original model. The main difference is the weights used to scale the observations.

Therefore, correct answer will be:-  Coefficient estimates from the un-weighted, original model should be used for prediction

This can cause estimates to differ depending on the weight chosen. When interpreting the coefficient estimates, it is important to consider the weights used when calculating the model. This is because they can affect the magnitude of the coefficient estimates.

Additionally, the weights should be taken into account when calculating the marginal effects of the coefficients. This can be done by scaling up the coefficients by the weight used. Ultimately, the interpretation of coefficient estimates from WLS should be done in the same manner as those from an un-weighted model, but the weights should be taken into account when considering their magnitude and when calculating marginal effects.

B) The participation rate was 11% greater in 2010 than in 2000.

This statement is correct because the participation rate increased from 44% to 55%, which is an increase of 11 percentage points. To express this as a percentage increase, we can use the formula:

Percentage increase = (new value - old value) / old value x 100%

Using this formula, we get:

Percentage increase = (55 - 44) / 44 x 100%

= 0.25 x 100%

= 11%

Therefore, the participation rate was 11% greater in 2010 than in 2000. Option B correctly expresses this result.

The optimal measure of variability is the IQR, which equals 4. The proper measure of variability for the data is C.

The difference among the third and the first quartile is defined by the interquartile range. The entire series is divided into four equally sized pieces by the partitioned values referred to as quartiles. Three quartiles are present.

The spread of the middle 50% of the data, which is less susceptible to outliers than the range, is measured by the interquartile range (IQR), which is the best measure of variability for these data.

The IQR is calculated by deducting the third quartile (\(Q_3\)) from the first quartile (\(Q_1\)). We can see from the box plot that \(Q_1\) is roughly

17 and \(Q_3\) is roughly 21.

Therefore,

\(IQR=Q_3-Q_1\\\\IQR=21-17\\\\IQR=4\)
