Answer:

166 1/2 in²

Step-by-step explanation:

The area of the quilt block= area of rectangel ABCD + area of right angled triangle AEF

=length*breath + 1/2*base* height

=16*9+1/2*6*7.5

=166.5 which also means 166 1/2 in²

let the unit place digit be x and tens place digit be y, therefore, the original number is 15.

then the two-digit number will be  10y + x

and the number formed by interchanging the unit place and tens place digits will be 10x + y

according to the first condition given in the qs i.e, the sum of two digits in the number is 6 that  is

x + y = 6

Also given that, if the original number is subtracted from the number formed by interchanging the digits, the result is 36.

i.e 10y +x - 10x -y = 36

     9(y-x) = 36

 y-x = 36/9

y-x = 4  and x+y = 6

solving both the above equations we will get ,

x= 1  and y = 5

since original number is 10y + x = 10(1) + 5

therefore, the original number is 15.

The required round of 7 /14 to the nearest 1/4 is itself 7 1/4.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,

7 1/4 rounded to the nearest 1/4 hour is 7 1/4. Rounding to the nearest 1/4 hour means finding the closest 1/4 hour mark, which in this case is 7 1/4 itself.

The measure of the angle is 54 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Let the measure of the angle "x".

The complement of the angle is 90 - x.

The supplement of the complement is 180 - (90 - x) = 90 + x.

The supplement of the angle is 36 less than the supplement of the complement of the angle, so 90 + x - 36 = x.

90 + x - 36 = x

54 = x

So the measure of the angle is 54 degrees.

Hence, the measure of the angle is 54 degrees.

The angle of rotation if an image is the result of a composition of two reflections across perpendicular lines is 180 degrees

Rotation and reflection are forms of transformation as seen in mathematics. The two are related in some forms.

here, we have,

When a reflection is done on a plane perpendicular to the preimage the image is reflected at the perpendicular plane. This is equal to rotation of an angle 90 degrees.

When the reflection is continued again across the perpendicular line, another reflection is noticed and similar rotation however in this case with respect to the initial image, the rotation is now 180 degrees.

A 95% confidence interval is wider than a 90% confidence interval and so provides a better estimate of the population mean.

A confidence interval represents the range of values within which the population mean is estimated to lie with a certain degree of confidence. The wider the interval, the more certain we can be that the population mean lies within it. In other words, a 95% confidence interval provides a better estimate of the population mean than a 90% interval because it is wider and therefore more likely to contain the true population mean.

This increased accuracy is particularly important for the city in their budget planning as it allows them to make more informed decisions based on a more reliable estimate of their expected daily income from parking fees.

Answer:

Step-by-step explanation:

The answers you have are in (x, y) form

Looking at first answer, -3 is the x and -1/2 is the y. We plug in the -3 as the x in each equation and hope to get -1/2.

So for (-3, -1/2)

y = 1/2(-3) + 1 = -3/2 + 1 = -1/2

Now the other equation

y = 3/2(-3) + 4 = -9/2 + 4 = -1/2

Since we got -1/2 as both. which is also the Y coordinate, this must be the answer. If it wasn't, we could keep going through the answer choices doing the same method.

The radius of the circle is 20/π units or approximately 6.37 units.

To find the radius of the circle given its central angle and arc length, we can use the formula:

arc length = radius * central angle

In this case, we have:

arc length = 4 units

central angle = 144°

Plugging these values into the formula, we get:

4 units = radius * 144°

To solve for the radius, we need to convert the angle from degrees to radians, as the formula requires the angle to be in radians.

1 radian = 180°/π

So, 144° = (144/180) * π radians

Simplifying, we have:

144° = (4/5) * π radians

Now we can rewrite the formula using radians:

4 units = radius * (4/5) * π radians

Solving for the radius, we divide both sides of the equation by (4/5) * π:

radius = (4 units) / ((4/5) * π)

Simplifying further, we can multiply the numerator and denominator by 5 to cancel out the fraction:

radius = (20 units) / π

Thus, the radius of the circle is 20/π units or approximately 6.37 units.

The independent variable caused changes in the dependent variable, then the Pearson’s Correlation Coefficient must be close to either +1 or -1

In order to determine if changes in an independent variable cause changes in a dependent variable, the researcher must use a measure of correlation. The most commonly used measure of correlation is Pearson’s Correlation Coefficient (r). This coefficient measures the strength and direction of the linear relationship between two variables. It can range from -1 to +1 and can be calculated using the formula r = (Σxy) / (√Σx2 * √Σy2).

The value of r indicates the strength of the relationship between two variables. A value of 0 indicates no correlation, a value of 1 indicates a perfect positive correlation, and a value of -1 indicates a perfect negative correlation. The closer the coefficient is to +1 or -1, the more confident the researcher can be that changes in the independent variable caused changes in the dependent variable. If the researcher is very confident that changes in the independent variable caused changes in the dependent variable, then the Pearson’s Correlation Coefficient must be close to either +1 or -1.

The two statements that are true are that the two histograms have different ranges of data and different distributions of data.

The first statement that is true is that the two histograms have different ranges of data. To calculate the difference in range, you can use the formula Range = Maximum - Minimum, where Maximum is the largest value in the sample, and Minimum is the smallest value in the sample. This means that if the maximum value of the first histogram is, say, 10 and the minimum value of the second histogram is 15, the difference in range between the two histograms is 5. The second statement that is true is that the two histograms have different distributions of data. This can be determined by looking at the shape of the histograms. For example, if the first histogram is clustered around a certain range of values, while the second histogram is more evenly distributed, this would indicate two different distributions.

As per the given data on the day 0, there are 500 bacteria in a dish.

The number of bacteria that doubles every day after that.

Here we have to determine that how many bacteria which represent y are there after x number of days.

Therefore, the number of bacteria after every day will form a geometric progression (G.P) with the first term as a = 500 and the common ratio as r = 2

Therefore [tex]\mathrm{a}_3=\mathrm{ar}^2=(500)(2)^2=2000[/tex]

Therefore, the number of bacteria at the end of 2nd day will be 480

[tex]$a_5=a^4=(500)(2)^4=8000[/tex]
