Step-by-step explanation:

You want the center of dilation when ∆ABC is dilated by a factor of 1/2 to get ∆AED.

In any dilation, the center of dilation is invariant. It doesn't move.

Since point A is common to both triangles, it didn't move. Point A is the center of dilation.

The number of coins which Craig collected as calculated from the given data is 49.

Given ,

percentage of foreign coin = 72%

Therefore the percentage of normal coins will be 28%.

Hence , the number of normal coins which he collected can be found out as ,

 28% of 175

= 28% × 175

= 28/100 × 175

= 0.28 × 175

= 49

When we divide a given number by 100 as a fraction , the result we get is known as percentage .

It is represented by the percentage sign which is "%".

The percentage is denoted by the letters "pct" or "pc," respectively. In other words, the percent or % is calculated at a value of around 100 and represents the proportion of one quantity made up of another.

Answer:

x = 302/999

HERE THE ANSWER

Step-by-step explanation:

The estimate made by Warner is 95% reasonable.

Given is that Warner received 7 letters and each letter weighed between 3.92 ounces and 4.1 ounces.

If the we take the maximum possible weight of each letter, which is 4 ounces, then the total weight of 7 letters will be equal to (4 x 7) = 28. But since the weights are weighted between 3.92 ounces and 4.1 ounces, let us assume that the weight of each letter is equivalent to -

w(a) = (3.92 + 4.10)/2 = 8.02/2 = 4.01

So, the weight of 7 letters would be -

W{7} = w(a) x 7 = 7 x 4.01 = 28.7

28.7 = 29 (round off) ≈ 30

So, yes the estimate of the Warner is reasonable.

Therefore, the estimate made by Warner is 95% reasonable.

The product of linear factors of the given polynomial are;

(x + 3 )*(x² + 2x + 50 + (−100/(x + 3)))

We are given the polynomial expression as;

g(x)= x³ + 5x² + 56x + 150

Now, we are told that  -3 is a zero. Thus, if -3 is a zero that means x = -1

and x + 3 is a factor.

Using online polynomial division calculator, the the polynomial is divided by (x + 3) to get;

(x³ + 5x² + 56x + 150)/(x + 3) = x² + 2x + 50 + (−100/(x + 3))

Answer:

Let x be the larger angle and y be the smaller angle

Larger angle is 2 less than 3 times the smaller angle that is x = 3y - 2

As the angles are complementary, their sum equals 90°

or, x + y = 90°

or, 3y - 2 + y = 90°

or, 4y = 92°

or, y = 23°

So, x = 3 * 23 - 2 = 67°

Larger angle = x = 67°

Smaller angle = y = 23°

Although part of your question is missing, you might be referring to this full question: The radius of a spherical ball is increasing at a rate of 2 cm/min. At what rate is the surface area of the ball increasing when the radius is 8 cm? The surface area of a sphere with radius r is given by 4πr².

The rate at which the surface area of the ball increasing when the radius is 8 cm is 128 cm²/min.

Given A = 4πr²

So, we have:

dA/dt = d/dt (4πr²)

= 4π * d/dt * (r²)

= 4π * 2r * dr/dt

= 8πr * dr/dt

Now, we have that dr/dt = 2 cm/min. So, when the radius of the ball is 8 cm, we have that:

dA/dt = 8πr * dr/dt

= 8π * 8 * 2

= 128π

Since we are measuring area, our unit is cm²/min, not cm/min.

Thus, the rate at which the surface area of the ball increasing when the radius is 8 cm is 128 cm²/min.

Based on the values you've listed, it appears that the expression P(7, 5) represents a combination calculation. In combinatorics, the notation P(n, k) represents the number of ways to choose a subset of k items from a set of n items, without regard to the order in which the items are chosen. This is also known as the number of k-permutations of n items.

In this case, the expression P(7, 5) would represent the number of ways to choose a subset of 5 items from a set of 7 items. Using the formula for combinations, this would be calculated as follows:

P(7, 5) = 7! / (5! * (7 - 5)!)

= 7! / (5! * 2!)

= 7 * 6 * 5 * 4 * 3 / (5 * 4 * 3 * 2 * 1 * 2 * 1)

= 7 * 6 / 2

= 21

Therefore, the correct answer for the expression P(7, 5) is 21.

The probability of getting a head and a number greater than 5 i.e, independent events is 0.0833.

A coin is tossed and a die is rolled. These are two independent events. Two events are defined as independent if the outcome of one event has no effect on the outcome of another event. The probability is calculated by multiplying two independent probabilities together, i.e, P(A and B) = P(A) x P(B)

We have, Let us assume two independent events be ,

A : A coin is tossed and the head is thrown.

B : A die is rolled, and a number greater than 5 occurs.

Total possible outcomes when a coin tossed = 2 ={ H ,T }

Total possible outcomes when a die rolled = 6 = { 1,2,3,4,5,6} .

We have to determine probability of getting a head and a number greater

than 5.

Probability of getting the head on toss a coin, P(A) = 1/2

Probability of occuring a number greater than 5 on rolling a die = P(B) = 1/6

So, the probability of getting a head on coin and a number greater than 5 on die =P(A)×P(B)

=(1/2)× 1/6 = 1/12=0.0833

The required linear inequality is [tex]-\frac{2}{3} \geq -\frac{7}{8}x[/tex]

What is linear inequation?

A linear inequation is an equation that contains one or more variables, such as x, and involves linear functions. Unlike a linear equation, its solution set is not a single point, but a range of values. Linear inequations are used to represent situations where the exact value of a variable is not known, but a range of values can be determined based on certain conditions. For example, if x represents the amount of money a person makes in a year and we know that it must be greater than $50,000, then we can write the linear inequation x > 50,000.

Let the number be x

The statement 'the confidence interval for the mean of y is always narrower than the prediction interval for an individual response y given the same data set, x value, and confidence level.' is True.

In this question, we have been given a statement 'The confidence interval for the mean of y is always narrower than the prediction interval for an individual response y given the same data set, x value, and confidence level. '

We need to state whether the given statement is true or false.

We know that the confidence interval = sample mean ± margin of error

The confidence interval  for the mean of y is narrower when the x value is close to the mean of all of the x values.

Therefore, the confidence interval for the mean of y is always narrower than the prediction interval for an individual response y given the same data set, x value, and confidence level is True.
