Answer:

7ft in length and 9.5 in width

Step-by-step explanation:

The length of the rectangular garden will be 9.625 feet.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Mike and Aimee are wanting to construct a nursery in their recently bought home. At first, they needed that to be 7 feet long and 4 feet in width. As of late, they found that they could expand the size of the nursery, however, Aimee needed to keep up with a similar corresponding relationship.

If they enlarge the size of the garden to a width of 5.5 feet.

Let 'x' be the length of the garden. Then the equation is given as,

x / 5.5 = 7 / 4

x / 5.5 = 1.75

x = 9.625 feet

The length of the rectangular nursery will be 9.625 feet.

Answer:

A shows all possible combinations

Step-by-step explanation:

The given expression c(x)=4x2-30x 500 represents the total cost of producing x items. This expression is a quadratic function, and it has a parabolic shape.

The coefficient of the x^2 term is positive, indicating that the parabola opens upward. This means that the cost initially increases as the number of items produced increases, but eventually, the cost starts decreasing as the production level becomes too high.
To find the minimum cost of production, we need to find the vertex of the parabola. The x-coordinate of the vertex is given by -b/2a, where a and b are the coefficients of the x^2 and x terms, respectively. In this case, a=4 and b=-30, so the x-coordinate of the vertex is x=30/8=3.75.
To find the minimum cost, we need to substitute this value of x into the expression c(x). c(3.75) = 4(3.75)^2 - 30(3.75) + 500 = $281.25. Therefore, the minimum cost of producing x items is $281.25.
In conclusion, the given expression c(x)=4x2-30x 500 represents the total cost of producing x items. The minimum cost of production is $281.25, and this occurs when 3.75 items are produced.

Systematic errors are consistently in the same direction

In contrast , random errors produce different values in random directions

Random error causes a slight difference of one measurement to from the next. It is quite unpredictable in it's variation during an experiment.

Systematic error always affects measurements by the same proportion, provided that a reading is taken the same way each time. It is predictable

for ease for I got approximate numbers.

The unit cost of apples is found to be $5.5 per pound. So the cost of 7.9 pounds of apple will be 43.45.

Here we have to calculate the value of a pound of apple from the given data, and then should multiply the unit value to find the cost of the given weight.

Weight of apple that was purchased = 3.3 lbs.

Cost of 3.3 lbs. of apples = 18.15

Cost of a pound of apple = Cost of apples purchased/ weight of apples purchased

= 18.15/3.3 = 5.5.

So each pound of apple will cost $5.50.

Weight of apple to be purchased = 7.9 lbs.

Cost of the apples = Weight of apples × unit price

                               = 7.9 × 5.50 = 43.45.

So the cost of 7.9 pounds  of apple will be $43.45.

If you begin with one dollar a day there will get you more by the end of the month because on day 2 your on 201 already which is more than you get in that month with one cent.

The first option (A) will give you more money than option (B).

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

Given that

Case A). Doubling each day

1 + 2+ 4 + 8 + 16 .... it is form a GP series with common ratio (r) 4/2 = 2

Number of terms (n)

Sum =  30( \(2^{30}\) - 1)/(2 - 1) = $2147483464.

Case B). Adding $100 each day

1 + (101 + 201 + 301 ....) it is form a ap series with common difference d = 201 - 101 = 100.

Number of terms = 29

Sum = 1 + 29/2 + [ 2 (101) + 28(100)] = $43530

Hence it is clear that case (A) will give you more money.

The mean height of the students in the class is 168.06 cm. The median height is 167.5 cm, and the modal height is in the range of 166-169 cm.

To find the mean, median, and modal height of the students in the class, we can use the given distribution of heights.

The distribution of heights and the corresponding number of students are as follows:

Height (in cm) No. of students

160-163 15

163-166 118

166-169 142

169-172 127

172-175 18

Mean:

To find the mean height, we can calculate the weighted average using the midpoint of each height range and the number of students in each range.

Mean = (15 * 161.5 + 118 * 164.5 + 142 * 167.5 + 127 * 170.5 + 18 * 173.5) / (15 + 118 + 142 + 127 + 18)

Mean = 168.06 cm

Median:

The median is the middle value of the data when arranged in ascending order. Since the distribution is already provided, we can determine the median by finding the midpoint of the total number of students.

Total number of students = 15 + 118 + 142 + 127 + 18 = 420

Median position = (420 + 1) / 2 = 210.5

The median falls within the 166-169 cm height range. Therefore, the median height is 167.5 cm.

Modal height:

The modal height is the height value that appears most frequently in the data. In this case, the height range with the highest number of students is the modal height. According to the data, the 166-169 cm height range has the highest frequency, with 142 students.

Answer:

The slope intercept form of (0,3) and (4,2) is y= -1/4x+3

Step-by-step explanation:

The distance from our y values from 3 to 2 is -1.

The distance from our x values is 4.

We can put these values as our slope and we know that the Y values are always rise and the x values are always run

Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.

The sum of the residuals and what it tells us about the line of best fit is that: −1.06; This indicates that the line of best fit is not very accurate and is not a good model for prediction.

Mathematically, the residual value of a data set can be calculated by using this formula:

Residual value = actual value - predicted value

Next, we would determine the predicted values as follows:

At point (4, 6), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(4) − 0.76.

Predicted value, y = 5.08

At point (6, 7), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(6) − 0.76.

Predicted value, y = 8.

At point (7, 8), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(7) − 0.76.

Predicted value, y = 9.46.

At point (9, 13), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(9) − 0.76.

Predicted value, y = 12.38.

At point (10, 14), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(10) − 0.76.

Predicted value, y = 13.84

At point (11, 15), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(11) − 0.76.

Predicted value, y = 15.3.

Now, we can calculate the sum of the residuals as follows:

Sum of the residuals = Sum of actual values - Sum of predicted values

Sum of the residuals = (6 + 7 + 8 + 13 + 14 + 15) - (5.08 + 8 + 9.46 + 12.38 + 13.84 + 15.3)

Sum of the residuals = 63 - 64.06

Sum of the residuals = -1.06.

Calculate AC using the distance formula

d = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )

AC = \(\sqrt{(3-0)^2+(5-(-2)})^2\)

     = \(\sqrt{3^2+(5+2)^2}\)

    = \(\sqrt{9+7^2}\)

    = \(\sqrt{9+49}\)

    = \(\sqrt{58}\)

The "d" format specifier is used to denote a signed decimal integer in various programming languages and formatting systems.

When used in format strings or printf-style functions, the "d" specifier indicates that the corresponding argument should be formatted as a signed decimal integer. It allows for the representation of both positive and negative whole numbers, including zero.

For example, in C programming, the printf function can be used with the "%d" format specifier to display a signed decimal integer value. Similarly, in other languages such as Python, the "{:d}" format specifier can be used with the format() function or string interpolation to represent a signed decimal integer.

Using the "d" specifier ensures that the output is formatted as a base-10 representation of a signed integer, taking into account the sign of the number.
