Answers

Answer 1

The information is provided below using a random sampling from a healthy population. a 90% confidence interval for . 114 is the lower bound of the confidence interval.

To find the lower bound of the 90% confidence interval, we need to calculate the 5th percentile of the data. To do this, use the formula that goes like this:

5th percentile = 114 + (0.90 * (512 - 114))

= 114 + (0.90 * 398)

= 114 + 358.2

= 472.2

Therefore, the lower bound of the 90% confidence interval is 472 (rounded to the nearest integer).

What does 1.022 represent in the expression?

Answers

Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."

In this instance, we're assuming that we can use the following function to simulate the US GDP, or gross domestic product, in dollars:

[tex]GDP = 11(1.0220)^{t}[/tex]

We can also see that the exponential model formula given by: governs this formula.

[tex]GDP = 11(1.0220)^{t[/tex]

Where a denotes the starting sum, b the model's growth/decay rate, and t is the number of years since 1950.

The value of b in this instance is provided by:

b = 1.022

And when we calculated r as the growth rate, we obtained:

1.022 = 1 + r

r = 1.022 - 1

r = 0.022

Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."

6. Applying the inscribed angle theorem, x = 33

7. m<ABP = 90°.

m<APB = 48°

What is the Tangent Theorem?

The tangent theorem states that the tangent of a circle is perpendicular to the radius of that circle and therefore forms a right angle at the point of tangency.

What is the Inscribed Angle Theorem?

An inscribed angle has a measure that is half the measure of the intercepted arc, according to the inscribed angle theorem.

Therefore:

Question 6:

Based on the inscribed angle theorem,

Measure of arc AB = 2(x + 3) = 2x + 6

108 + 2x + 6 = 180 [semicircle]

Solve for x

114 + 2x = 180

2x = 180 - 114

2x = 66

x = 33

Question 7:

Given that line PB is tangent to circle A, therefore, based on the tangent theorem, the measure of angle ABP = 90°.

How do you dilate an image?

Answers

To dilate an image , multiple the scale factor with the coordinates

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.

The resizing happens from a point called the center of dilation. It is the center of dilation from which the objects/figures are expanded or contracted.

Scale factor is a number by which the size of any geometrical figure can be changed with respect to its original size.

Follow the steps below to dilate an image.

Step 1: Determine the scale factor and the dilation centre.

Step 2: Identify an image vertex. Draw a line through one of the image's vertices from the centre of dilation.

Step 3: Determine the horizontal and vertical distances between the dilation centre and the vertex.

To find the horizontal and vertical distances from the centre of dilation to a new vertex, multiply the distances by the scale factor.

Step 4: Determine the new horizontal and vertical distances from the centre of dilation. Make a point plot.

Step 5: Join the new vertices together to create the dilated image.

A llama weighing 200kg needs to be transported on a stretcher, The upward acceleration on the stretcher is 0.63m/s². What net force is needed to accelerate the llama on the stretcher?

Answers

The net force is 126 kg m/s² needed to accelerate the llama on the stretcher.

To determine the net force needed to accelerate a llama weighing 200 kg on a stretcher with an upward acceleration of 0.63 m/s², we can use the formula F = ma, where F is the net force, m is the mass of the llama, and a is the upward acceleration of the stretcher.

As per the question, the mass of the llama is 200 kg and the upward acceleration of the stretcher is 0.63 m/s²,

So, the net force needed to accelerate the llama is:

F = 200 kg × 0.63 m/s²

F = 126 kg m/s².

Thus, the net force is 126 kg m/s² needed to accelerate the llama on the stretcher.

If you start with 1 and repeatedly multiply by 1/2, will you reach 0? Explain why or why not.

Answers

Answer:

nope

Step-by-step explanation:

1 multiplied by 1/2 just equals 1/2 since it's being multiplied by one, it wouldn't matter if you kept multiplying 1/2 either because the numerator will stay the same regardless, and the denominator just gets bigger and bigger since you're multiplying by two. if the numerator wasn't 1 then I'm sure there's a possibility, but in this scenario, it's not.

Answer: You will reach 0

Step-by-step explanation:

Yes, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.

To see why this is the case, let's consider the following sequence of numbers:

1 * (1/2) = 0.5

0.5 * (1/2) = 0.25

0.25 * (1/2) = 0.125

0.125 * (1/2) = 0.0625

0.0625 * (1/2) = 0.03125

As you can see, each time we multiply by 1/2, the result is half of the previous number. Because any number multiplied by 0 is 0, we will eventually reach 0 if we keep multiplying by 1/2.

Therefore, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.
