What is multiplicative rate of change?The multiplicative rate of change is a number by which we get another number from the previous number, to get the value of this number , we have to divide the other number from the previous number.
Suppose
first number = X
second number = Y
second number is 15% more than first number
So, Y = X + 15% of X
Y = X + 0.15X
Y = 1.15 X
for multiplicative rate of change we have to apply divide operation,
⇒ P = Y/X
⇒ P = 1.15X/X
⇒ P = 1.15
Hence, the result is 1.15

Answers
The correct transformation that describes why rectangles ABCD and A′B′C′D′ are similar is Rectangle ABCD was dilated by a scale factor of 5 to form rectangle A′B′C′D′.
Dilation is a transformation that changes the size of an object while maintaining its shape. In this case, the coordinates of rectangle ABCD were multiplied by a scale factor of 5 to obtain the coordinates of rectangle A′B′C′D′.
This means that each side length of rectangle ABCD was multiplied by 5 to get the corresponding side length of rectangle A′B′C′D′.
The reflection across the y-axis and the rotation of 90° counterclockwise would result in different shapes and orientations, not maintaining the similarity between the two rectangles.
The dilation by a scale factor of 15 or 1/5 would also change the proportions and not result in a similar rectangle.

A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, is given by h(t)= −4.9t^2+11t+7. How many seconds does it take to reach maximum height? Enter the answer with at least 3 decimal places.
Answers
Given statement solution is :- It takes approximately 1.122 seconds for the ball to reach its maximum height.
To find the time it takes for the ball to reach its maximum height, we need to determine the vertex of the parabolic function given by the equation h(t) = \(-4.9t^2 + 11t + 7.\)
The vertex of a parabola in the form y = \(ax^2 + bx\) + c is given by the formula t = -b / (2a).
Comparing the equation h(t) = \(-4.9t^2 + 11t + 7\) to the standard form, we have:
a = -4.9
b = 11
Using the formula for the vertex, we can calculate the time it takes to reach the maximum height:
t = -11 / (2 * -4.9)
t = -11 / -9.8
t ≈ 1.122
Therefore, it takes approximately 1.122 seconds for the ball to reach its maximum height.

On a map, 1 inch equals miles. If two cities are 3 inches apart on the map, how far are they actually apart?
Answers
Answer: as many miles as 3 inches is
Step-by-step explanation:
To determine the actual distance between two cities when given a scale on a map, we can use the concept of ratios and proportions.
In this case, we are told that 1 inch on the map represents a certain number of miles. Let's say that 1 inch on the map represents x miles.
We can set up the following proportion:
1 inch / x miles = 3 inches / y miles
Using cross-multiplication, we have:
1 inch * y miles = 3 inches * x miles
Simplifying the equation:
y miles = 3 inches * x miles
Now, we can substitute the given value of 3 inches for the distance on the map:
y miles = 3 inches * x miles
To find the actual distance between the cities (y miles), we need to know the value of x, which represents the number of miles represented by 1 inch on the map. Without that information, we cannot calculate the actual distance between the cities.

Show that the angle bisector of an equilateral triangle is perpendicular to the base
Answers
To show that the angle bisector of an equilateral triangle is perpendicular to the base, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.
How to prove that the angle bisector is perpendicular to baseAfter getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.
We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.
Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.
Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

An English teacher counted the number of misspelled words in a 1000-word essay he assigned to his students. From a group of 49 students, the mean number of misspelled words was 9.1. The distribution of the student population is normal with a variance of 12.25. What is a confidence interval for the mean number of misspelled words in the student population, considering a confidence level of 99.7%? (Use 3 for the Z value in the formula below)
Answers
Confidence Interval = Mean ± (Z * (Standard Deviation / √(Sample Size)))
Given:
Mean (μ) = 9.1 (mean number of misspelled words)
Sample Size (n) = 49 (number of students)
Variance (σ^2) = 12.25 (variance of the distribution)
Standard Deviation (σ) = √(Variance) = √(12.25) = 3.5
Confidence Level = 99.7% (which corresponds to a Z-value of 3)
Substituting the values into the formula:
Confidence Interval = 9.1 ± (3 * (3.5 / √(49)))
Calculating the expression within the parentheses:
Confidence Interval = 9.1 ± (3 * (3.5 / 7))
Simplifying:
Confidence Interval = 9.1 ± (3 * 0.5)
Confidence Interval = 9.1 ± 1.5
Therefore, the confidence interval for the mean number of misspelled words in the student population, considering a confidence level of 99.7%, is:
Confidence Interval = (9.1 - 1.5, 9.1 + 1.5)
Confidence Interval = (7.6, 10.6)
Answer:
C. [7.6, 10.6]
Step-by-step explanation:
To calculate the confidence interval for the mean number of misspelled words in the student population, we can use the confidence interval formula:
\(\boxed{CI=\overline{x}\pm z\left(\dfrac{s}{\sqrt{n}}\right)}\)
where:
\(\overline{x}\) is the sample mean.z is the confidence level value.s is the sample standard deviation.n is the sample size.Given values:
\(\text{Mean}\;\overline{x} = 9.1\)\(\text{Variance}\;s^2=12.25\)\(\text{Sample size}\;n=49\)The standard deviation is the square root of the variance:
\(s=\sqrt{s^2}=\sqrt{12.25}=3.5\)
The empirical rule states that approximately 99.7% of the data points will fall within three standard deviations of the mean.
Therefore, z-value for a 99.7% confidence level is z = 3.
Substituting these values into the formula, we get:
\(CI=9.1\pm 3\left(\dfrac{3.5}{\sqrt{49}}\right)\)
\(CI=9.1\pm 3\left(\dfrac{3.5}{7}\right)\)
\(CI=9.1\pm 3\left(0.5\right)\)
\(CI=9.1\pm 1.5\)
Therefore, the 99.7% confidence limits are:
\(CI=9.1-1.5=7.6\)
\(CI=9.1+1.5=10.6\)
Therefore, the confidence interval for the mean number of misspelled words in the student population is [7.6, 10.6].

c. a probability of being correct, which is equal to the P-value
d. a probability of being correct, which is equal to 1-(P-value)
Answers
Answer:
a. committed a type 1 error
Step-by-step explanation:
The correct option is - a. committed a type 1 error
Reason -
Type 1 error occurs when a true null Hypothesis is rejected
Type 2 error occurs when a false null Hypothesis is accepted
Now,
Let us state that,
The null hypothesis and alternate hypothesis is
H0 : There is no difference between the mean lifetimes of the new and old designs
H1 : There is a difference between the mean lifetimes of the new and old designs
Now,
As there is no difference between the mean lifetimes of the new and old designs.
⇒ The null hypothesis is true.
But p value suggests that null hypothesis should be rejected
∴
We have committed a Type 1 error that is rejecting a true null hypothesis.
So,
The correct option is - a. committed a type 1 error

salesperson earns $345 for selling $2300 in merchendice find the commison rate
Answers
Answer:
The commission rate is 15%
Step-by-step explanation:
commission = commission rate x sales
where the commission rate is expressed as a decimal.
In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:
345 = commission rate x 2300
To solve for the commission rate, we can divide both sides by 2300:
commission rate = 345/2300
Simplifying this expression, we get:
commission rate = 0.15
So, the commission rate is 15%
