The number 1.092 × 10¹ is 15.6 times larger than  7 × 10⁻¹ .

A number is said to be in standard form if it can be written in a decimal number between 1.0 and 10.0 multiplied with power of 10.

For Example: 1.8x10² is a standard form .

In the given question

1.092×10¹   and    7×10⁻¹

both the numbers are in a standard form

For comparison we need to convert them in decimal form

1.092 × 10¹ = 1.092 x 10 = 10.92

7 × 10⁻¹ = 7/10 = 0.7

So , According to the question

Let 10.92 be x times larger than 0.7

which means

(0.7)*x=10.92

x=10.92/0.7

x=15.6

Therefore , 1.092 × 10¹ is 15.6 times larger than  7 × 10⁻¹ .

Answer:

Range is between -7 and 8

-7<y<8

Step-by-step explanation:

Range means series of number between lowest and highest output(y-axis) of a function.

Notice on the graph, the lowest y you can get is -7 and highest is 8. Other numbers are in between.  

Thus,  the range is in between of -7 and 8.

According the inscribed angle theorem, t = 76°. The inscribed angle theorem postulates that the inscribed angles subtended by the same arc are equal.

Step 1: Note that the line segment YX can be used to create an arc.

Step 2: Since the vertexes 76° and t° are subtended by the same arc, that makes t = 76°.

Note: An arc, line segment, or other portion of a curve subtends an angle when its two rays pass through the endpoints of that arc, line segment, or curve section.

So the correct answer is m∠t = 76°

Answer:

Three perpendicular bisectors are required

Step-by-step explanation:

A perpendicular bisector of a line segment is a line that cuts the line segment at a 90° angle, dividing it into two equal halves.

In this example, one bisector produces two equal parts of the segment

two bisectors produce three segments and three bisectors, four segments as shown in the diagram.

Perpendicular bisectors are constructed using a compass and a pencil, you can check out how to construct one, it is pretty interesting.

To determine which differential equation(s) are linear, we need to examine the form of each equation. A linear differential equation is one that can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x), b(x), c(x), and g(x) are functions of x.

The differential equation 2xy" - 5xy' + y = sin(3x) is linear. It can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x) = 2x, b(x) = -5x, c(x) = 1, and g(x) = sin(3x).
The differential equation (v)² + xy = In(x) is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (v)², where v represents the derivative of y with respect to x. This term does not have a linear coefficient.
The differential equation y' + sin(y) = e^(3x) is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = sin(y), and g(x) = e^(3x).
The differential equation (x²+1)y" - 3y - 2x³y = -x - 9 is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (x²+1)y", where the coefficient is a function of x.
The differential equation y' + xy = y" is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = x, and g(x) = y".

The statement that best defines the term "experiment" in the context of probability is (a) "A process that leads to only one of several possible outcomes."

An experiment is a process that is carried out to observe and study the outcome of an event or phenomenon. In probability, an experiment refers to a process that can have multiple outcomes, and the outcome cannot be predicted with certainty before the experiment is carried out.

For example, rolling a dice is an experiment in probability since it has multiple possible outcomes (rolling a 1, 2, 3, 4, 5, or 6) and the outcome cannot be predicted with certainty. Similarly, flipping a coin is also an experiment in probability since it can have two possible outcomes (heads or tails) and the outcome cannot be predicted with certainty.

On the other hand, option (b) is incorrect since a random trial whose outcome can be predicted on the basis of mathematical analysis is not an experiment but a deterministic process. Option (c) is also incorrect since a process that may or may not confirm a hypothesis does not define an experiment in the context of probability.

The correct answer is (a). fail to reject the null hypothesis at null= 0.05 and all larger null.

The null hypothesis (H0) in this case is that β1=0, meaning that there is no relationship between the independent and dependent variables in the regression study.

The alternative hypothesis (Ha) is that β1≠0, meaning that there is a relationship between the independent and dependent variables.

The 95% confidence interval for β1 is (-5.65, 2.61). This means that we are 95% confident that the true value of β1 falls within this range. Since the range includes 0, we cannot reject the null hypothesis that β1=0.

Therefore, we fail to reject the null hypothesis at a significance level of 0.05 (null=0.05) and all larger significance levels.

In other words, there is not enough evidence to suggest that there is a relationship between the independent and dependent variables in the regression study, so we cannot reject the null hypothesis.

Hence, fail to reject the null hypothesis at null=0.05 and all larger null is the correct answer, i.e., option (a)

  (x +4)² +(y -9)² = 121

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

__

We are given that (h, k) = (-4, 9) and r = 11. When we put these values into the equation, it becomes ...

  (x -(-4))² +(y -9)² = 11²

We can simplify this a bit to ...

  (x +4)² +(y -9)² = 121

The present value of the loan is found to be  approximately $70.28.

To find the present value of a loan, we can use the formula:

Present Value = Future Value / (1 + (interest rate * time))

Given that the future value is $1,321.17, the interest rate is 7.75%, and the time is 230 days, we can plug in these values into the formula:

Present Value = 1321.17 / (1 + (0.0775 * 230))

Calculating the expression in the parentheses first:

Present Value = 1321.17 / (1 + 17.8075)

Simplifying further:

Present Value = 1321.17 / 18.8075

Evaluating the division:

Present Value ≈ $70.28

Therefore, the present value of the loan is approximately $70.28.

The foci are located at the points (3+sqrt(8), 3) and (3-sqrt(8), 3), respectively. The smaller x-value is 3-sqrt(8).

The given curve has four sections, each of which is a quarter of an ellipse with a center at the point (3, 3). The major axis of the ellipse is the line segment connecting the points (3, 4) and (3, 2), and the minor axis is the line segment connecting the points (6, 3) and (0, 3). The length of the major axis is 2, and the length of the minor axis is 6. Thus, the equation of the ellipse is:

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

The foci of the ellipse can be found using the formula c = sqrt(a^2 - b^2), where a is the length of the major axis (1 in this case) and b is the length of the minor axis (3 in this case). The distance between the center of the ellipse and each focus is c. Thus, the foci are located at the points (3+sqrt(8), 3) and (3-sqrt(8), 3), respectively. The smaller x-value is 3-sqrt(8).

The margin of error is approximately 0.014 grams, rounded to three decimal places.

To construct a 98% confidence interval for the mean of repeated measurements of the weight, we can use the following formula:

CI = x ± z × (σ/√n)

Where:
x = mean result = 10.230 grams
σ = standard deviation of scale readings = 0.020 gram
n = number of repeated measurements = 40
z = z-score for 98% confidence interval = 2.326

Plugging in the values, we get:

CI = 10.230 ± 2.326×(0.020/√40)
CI = 10.230 ± 0.014
CI = (10.216, 10.244)

Therefore, the 98% confidence interval for the mean of repeated measurements of the weight is (10.216, 10.244) grams.

The margin of error is the difference between the upper and lower bounds of the confidence interval divided by 2, so:

Margin of error = (10.244 - 10.216)/2
Margin of error = 0.014

Thus, the margin of error is 0.014 grams.

Answer:

1) -1/3

2) 4

3) 5/2

4) 5/7

Step-by-step explanation:

To find slope, you must do rise/run, where rise is movement up and down, and run is movement left and right.

So just start from the left most point and count the little unit squares up or down to determine rise and then count them left or right to determine run, do this until you get to the next point. (If it's a positive slope then the line will go up to the right, and if it's negative then it will go down to the right).

For example: In the first graph, since the line is going down, the slope is negative. As you can see it goes down 1 and over to the right 3, so that's why it's presented as -1/3.
