The maximum error in volume of ball is ± 235.619 cm³

The margin of error, also known as the maximum error of estimation, is equal to one-half the breadth of a confidence interval and serves as a measure of how accurate an estimate is.

The formula for the confidence limits on can be written as follows: where is half of the confidence interval's breadth.

Volume of ball is given by:

V =  (4/3)πr³

Change in volume (ΔV) = (4/3)π × 3r² (Δr)

= 4π × 3r² (Δr)

= 4π × 3* 25² (±0.01)

= ± 235.619 cm³

The first five terms of the sequences are 2, 3, 5, 9, 17. and 1, 4, 7, 10, 13

Using the formula, an = 2an-1 - 1 where a1 = 2, we can find the first few terms of the sequence as follows:

a2 = 2a1 - 1 = 2(2) - 1 = 3

a3 = 2a2 - 1 = 2(3) - 1 = 5

a4 = 2a3 - 1 = 2(5) - 1 = 9

a5 = 2a4 - 1 = 2(9) - 1 = 17

Therefore, the first five terms of the sequence are: 2, 3, 5, 9, 17.

Answer:

Measure of one angle is required.

Step-by-step explanation:

Kindly refer to the image attached.

AM and BN are the two parallel lines cut by a transversal PQ.

The angles formed are:

\(\angle 1, \angle 2, \angle 3, \angle 4, \angle 5, \angle 6, \angle 7 \ and\ \angle 8\).

Let, only one of the angles is known to us.

Let, it is given that \(\angle 2 = 60^\circ\)

AM is a straight line, therefore

\(\angle 1+\angle 2 =180^\circ\\\Rightarrow \angle 1 =180-60=120^\circ\)

\(\angle 1\) and \(\angle 3\) are vertically opposite angles, therefore must be equal to each other.

\(\angle 1 = \angle 3 = 120^\circ\)

\(\angle 2\) and \(\angle 4\) are vertically opposite angles, therefore must be equal to each other.

\(\angle 2 = \angle 4 = 60^\circ\)

By Corresponding angle postulate, we can see the following:

\(\angle 2=\angle 5 =60^\circ\\\angle 3=\angle 6 =120^\circ\\\angle 1=\angle 8 =120^\circ\\\angle 4=\angle 7 =60^\circ\)

Therefore, by knowing just one angle, all the angles can be found.

Answer:

68°

Step-by-step explanation:

since the ball is placed or comes from a straight line (which is the wall) it means that when you add all those angles the final answer has to be 180 because angles in a straight line add up to 180°

68°+44°+1=180

112°+1=180

1=180-112

=68°

I hope this helps

The measure of ∠1 is 68 degrees.

We have Lisa who kicked a ball against the wall at the indicated angle.

We have to determine the measure of the angle 1 in degrees.

A straight line has an angle of 180 degrees.

According to question, we have -

∠3 = 68 degrees

∠2 = 44 degrees

Therefore -

∠3 + ∠2 + ∠1 = 180

68 + 44 + ∠1 = 180

112 + ∠1 = 180

∠1 = 180 - 112

∠1 = 68 degrees

Hence, the measure of ∠1 is 68 degrees.

Answer:

 \(\Large \text{$ \frac{1}{w^2} $}\)

Step-by-step explanation:

Given the exponential expression, \(\displaytext\mathsf{w^3\:\times\:w^{-5}}\), where it involves the multiplication of the same base, w, with varying powers.  

Using the Product Rule of Exponents, where it states that, \(\displaystyle\mathsf{a^{m}\:\times\:a^{n}\:=\:a^{(m\:+\:n)}}\).

Hence, we simply need to add the exponents:  

\(\displaytext\mathsf{w^3\:\times\:w^{-5}\:=\:w\:^{[3\:+\:(-5)]}\:=\:w^{-2}}\)

Next, apply the Negative Exponent Rule, where it states that: \(\displaystyle\mathsf{a^{-n}\:=\:\frac{1}{a^n}}\).

Transforming the negative exponent of  \(\displaytext\mathsf{w^{-2}}\)  becomes a positive exponent by using the Negative Exponent Rule.

  \(\displaytext\mathsf{w^{-2}\:=\:\frac{1}{w^2}}\)

The value of x is 10.6 which is equivalent to 11.

In the given triangle

the triangle is divided into two triangles which are both right angled

However in the bigger triangle

we would use the Pythagoras Theorem

( y + 6 )² = x² + 100 ---------- equation 1

In the smaller triangle;

x² = y² + 64 --------------equation 2

Thus substituting the value of x in equation 1

Thus the equation becomes

( y + 6 )² = y² + 64 + 100

y² + 36 + 12x = y² + 164

Cancelling y² on both sides we will get

36 + 12x = 164

12x = 164 - 36

this implies 12 x = 128

x = \(\frac{128}{12}\)

x = 10.6 ≈ 11

Thus the required value of x is 10.6 or 11

Let's assume the first odd integer is x. Since the next odd integer would be consecutive, we can represent it as x + 2.

According to the problem, the product of these two consecutive odd integers is 399:

x * (x + 2) = 399

Expanding the equation:

x^2 + 2x = 399

Rearranging the equation into a quadratic form:

x^2 + 2x - 399 = 0

To solve this quadratic equation, we can either factor it or use the quadratic formula. Let's use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 1, b = 2, and c = -399.

x = (-2 ± √(2^2 - 4 * 1 * -399)) / (2 * 1)

Simplifying:

x = (-2 ± √(4 + 1596)) / 2

x = (-2 ± √1600) / 2

x = (-2 ± 40) / 2

Now, we can calculate the two possible values for x:

x = (-2 + 40) / 2 = 38 / 2 = 19

x = (-2 - 40) / 2 = -42 / 2 = -21

Since we are looking for consecutive odd integers, we take the positive value of x, which is 19. The next consecutive odd integer would be 19 + 2 = 21.

Therefore, the two consecutive odd integers whose product is 399 are 19 and 21.

 The correct option is G: 3,-7.

Explanation: To find the solutions of the equation \(n^2 - 4n = 21\), we need to set the equation equal to zero and then solve for n.

First, let's move the constant term (21) to the other side of the equation, which gives us\(n^2 - 4n - 21 = 0\).

To solve this quadratic equation, we can factor it or use the quadratic formula. In this case, factoring may be a little challenging, so let's use the quadratic formula:

The quadratic formula states that for an equation of the form \(ax^2 + bx + c = 0\), the solutions are given by x = (-b ± √(b^2 - 4ac)) / (2a).

For our equation \(n^2 - 4n - 21 = 0\), a = 1, b = -4, and c = -21. Plugging these values into the quadratic formula, we get:

n = (-(-4) ± √((-4)^2 - 4(1)(-21))) / (2(1))
n = (4 ± √(16 + 84)) / 2
n = (4 ± √100) / 2
n = (4 ± 10) / 2

Now we have two possibilities:
1. n = (4 + 10) / 2 = 14 / 2 = 7
2. n = (4 - 10) / 2 = -6 / 2 = -3

Therefore, the solutions of the equation \(n^2 - 4n = 21\) are n = 7 and n = -3.

After the hurricane and the disease, 48% of the original population of rats is left.

We have,

After the hurricane, 40% of the rats were wiped out, which means

100% - 40% = 60% of the rats survived.

Then, after the disease spread through stagnant water, 20% of the remaining rats were killed.

This means 100% - 20% = 80% of the rats that survived the hurricane are still left.

To find the percentage of the original population of rats that is left after both events, we multiply the percentages:

Percentage left = 60% * 80% = 0.6 * 0.8 = 0.48

Finally, we convert the decimal value back to a percentage:

Percentage left = 0.48 * 100% = 48%

Answer:

The answer is -8 :)

Step-by-step explanation:

If two methods agree perfectly in a method comparison study, the slope equals 1.0 and the y-intercept equals 0.0. Therefore, option (b) is the correct answer.

In a method comparison study, the goal is to compare the agreement between two different measurement methods or instruments. The relationship between the measurements obtained from the two methods can be described by a linear equation of the form y = mx + b, where y represents the measurements from one method, x represents the measurements from the other method, m represents the slope, and b represents the y-intercept.

When the two methods agree perfectly, it means that there is a one-to-one relationship between the measurements obtained from each method. In other words, for every x value, the corresponding y value is the same. This indicates that the slope of the line connecting the measurements is 1.0, reflecting a direct proportional relationship.

Additionally, when the two methods agree perfectly, there is no systematic difference or offset between the measurements. This means that the line connecting the measurements intersects the y-axis at 0.0, indicating that the y-intercept is 0.0.

Therefore, in a perfect agreement scenario, the slope equals 1.0 and the y-intercept equals 0.0, which corresponds to option (b).
