of a foot in 3 months. What was its rate of growth?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
feet per month
After calculation, we know that rate of growth of the seed is 2/9 feet in 1 month which is in proper fraction.
What is the rate of growth?Take the current number and subtract it from the prior value to determine the growth rate.
The growth rate is then expressed as a percentage by multiplying the difference by the previous number and dividing by 100.
The three types of growth identified by the Harrod-Domar model are warranted growth, real growth, and the natural rate of growth.
The economy cannot continue to develop at this rate indefinitely or without experiencing a downturn, which is known as the warranted growth rate.
The annual increase in a country's real GDP rate is known as actual growth.
So, we know that the seed grows:
2/3 foot in 3 months
Then, the rate of growth in 1 month was:
= 2/3 ÷ 3
= 2/3 ÷ 3/1
= 2/3 * 1/3
= 2/9 foot
Therefore, after calculation, we know that rate of growth of the seed is 2/9 feet in 1 month which is in proper fraction.

Mars Inc. claims that they produce M&Ms with the following distributions: | Brown || 30% ! Red || 20% || Yellow | 2090 | Orange || 10% || Green II 1000 || Blue || 1000 A bag of M&Ms was randomly selected from the grocery store shelf, and the color counts were: Brown 21 Red 22 Yellow 22 Orange 12 Green 17 Blue 14 Using the χ2 goodness of fit test (α-0.10) to determine if the proportion of M&Ms is what is claimed. Select the [p-value, Decision to Reject (RHo) or Failure to Reject (FRHo) a) [p-value = 0.062, RHO] b) [p-value# 0.123, FRH0] e) [p-value 0.877, FRHol d) [p-value 0.877. RHJ e) [p-value 0.123, RHol f) None of the abote
After performing the test, the calculated p-value was 0.062. Since the p-value is greater than the significance level of 0.10 (α), the decision is to fail to reject the null hypothesis.
The χ² goodness of fit test was conducted to determine if the proportions of M&M colors in a selected bag match the claimed distribution by Mars Inc. The observed counts of each color were compared to the expected counts based on the claimed percentages.
After performing the test, the calculated p-value was 0.062. Since the p-value is greater than the significance level of 0.10 (α), the decision is to fail to reject the null hypothesis. Therefore, there is not enough evidence to conclude that the proportion of M&Ms in the selected bag differs significantly from what Mars Inc. claims.
The χ² goodness of fit test is used to assess whether observed data follows an expected distribution. In this case, the expected distribution is based on the claimed proportions provided by Mars Inc.
The observed counts of M&M colors (Brown: 21, Red: 22, Yellow: 22, Orange: 12, Green: 17, Blue: 14) were compared to the expected counts derived from the claimed percentages (Brown: 30%, Red: 20%, Yellow: 20%, Orange: 10%, Green: 10%, Blue: 10%).
The χ² test statistic is calculated by summing the squared differences between observed and expected counts, divided by the expected counts. The degrees of freedom for this test are determined by the number of categories minus one (df = 6 - 1 = 5).
After calculating the χ² test statistic, the corresponding p-value is obtained. The p-value represents the probability of observing a test statistic as extreme or more extreme than the calculated value, assuming the null hypothesis (H0) is true. In this case, the null hypothesis is that the proportions of M&M colors in the selected bag match the claimed distribution.
Comparing the calculated p-value (0.062) to the predetermined significance level (α = 0.10), we find that the p-value is greater than α. Therefore, there is insufficient evidence to reject the null hypothesis. Consequently, the decision is to fail to reject the null hypothesis. This means that the observed proportions of M&M colors in the selected bag do not significantly differ from what Mars Inc. claims.

compute the critical value za/2 that corresponds to a 83% level of confidence
The critical value zₐ/₂ that corresponds to an 83% level of confidence is approximately 1.381.
To find the critical value zₐ/₂, we need to determine the value that leaves an area of (1 - α)/2 in the tails of the standard normal distribution. In this case, α is the complement of the confidence level, which is 1 - 0.83 = 0.17. Dividing this value by 2 gives us 0.17/2 = 0.085.
To find the z-value that corresponds to an area of 0.085 in the tails of the standard normal distribution, we can use a standard normal distribution table or a statistical calculator. The corresponding z-value is approximately 1.381.

The function f has a first derivative given by f′(x)=x(x−3)2(x+1). At what values of x does f have a relative maximum?
A -1 only
B 0 only
C -1 and 0 only
D -1 and 3 only
E -1, 0, and 3
The values of x where f has a relative maximum are -1 and 3. The answer is D, -1 and 3 only.
To determine the values of x where the function f has a relative maximum, we need to analyze the sign of the derivative in the neighborhood of each critical point.
The critical points of f correspond to the values of x where the derivative is equal to zero or undefined. In this case, the derivative is undefined only at x = -1, where there is a vertical asymptote.
To find the values of x where the derivative is zero, we set f'(x) = 0 and solve for x:
\(f'(x) = x(x-3)^2\)(x+1) = 0
This equation is satisfied when x = 0 or x = 3, since these are the only values that make one of the factors equal to zero. Therefore, these are the only two critical points of f.
Next, we can use the first derivative test to determine the nature of each critical point. This involves checking the sign of the derivative in the interval to the left and right of each critical point.
For x = -1, the derivative is undefined to the left and right, but we can still examine the sign of f'(x) in the vicinity of -1. For example, if we consider values of x slightly to the left of -1 (say, x = -1.1), we see that f'(x) is negative. Similarly, if we consider values of x slightly to the right of -1 (say, x = -0.9), we see that f'(x) is positive. This means that f has a relative maximum at x = -1.
For x = 0, the derivative is negative to the left and positive to the right. This means that f has a relative minimum at x = 0.
For x = 3, the derivative is positive to the left and negative to the right. This means that f has a relative maximum at x = 3.
Therefore, the values of x where f has a relative maximum are -1 and 3. The answer is D, -1 and 3 only.

The measure θ of an angle in standard position is given. -45°
a. Write each degree measure in radians and each radian measure in degrees rounded to the nearest degree.
The degree measure in radians is -π/4 and the radian measure in degrees is -45°.
To convert a degree measure to radians, we can use the formula: radians = degrees * (π/180).
To convert a radian measure to degrees, we can use the formula: degrees = radians * (180/π).
For the given measure of -45°, we can convert it to radians using the formula:
radians = degrees * (π/180)
radians = -45° * (π/180)
radians = -45π/180
radians = -π/4
To convert -π/4 radians to degrees, we can use the formula:
degrees = radians * (180/π)
degrees = -π/4 * (180/π)
degrees = -45°
Therefore, the degree measure in radians is -π/4 and the radian measure in degrees is -45°.

The sum of a two-digit number and another formed by reversing its digits is 99. Five added to the number yields 4 less than 6 times the sum of its digits. Find the number.
The number is 10x + y = 10 + 39 = 49.
To solve this problemLet the ten's digit be x and the unit's digit be y.
The number is 10x + y.
The number formed by reversing its digits is 10y + x.
10x + y + 10y + x = 99
21x + 2y = 99
Five added to the number yields 4 less than 6 times the sum of its digits.
10x + y + 5 = 6(x + y) - 4
10x + y + 5 = 6x + 6y - 4
11x - 5y = 1
We can solve the system of equations 21x + 2y = 99 and 11x - 5y = 1.
Multiplying the first equation by 5 and the second equation by 21, we get:
105x + 10y = 495
231x - 105y = 21
Adding the two equations, we get 336x = 516
Dividing both sides by 336, we get x = 1.
Substituting x = 1 in the equation 21x + 2y = 99, we get 21 + 2y = 99
2y = 78
y = 39
Therefore, the number is 10x + y = 10 + 39 = 49.

For a taxable income of $1,80,900, the effective tax rate is 21.11%.
what is meant by marginal tax?Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.
Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.
To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

\(t=\frac{80}{32}\)
\(t=2.5\) seconds
That means after 2.5 seconds ball will reach the maximum height.
By substituting \(t=2.5\) in the equation,
\(h=-16(2.5)^2+80(2.5)\)
\(h=100\) feet
Therefore, maximum height achieved by the ball is 100 feet.
32). If the ball follows the parabolic path,
Time taken by the ball to reach the maximum height = Time taken by the ball to come back to the ground from the maximum height.
Time taken by the ball to hit the ground = 2(2.5) = 5 seconds

How to determine the solution to the inequalityFrom the question, we have the following parameters that can be used in our computation:
y ≥3(0.8)^x
y ≥ x² - 5
Represent properly
y ≥ 3(0.8)^x
y ≥ x² - 5
Next, we make a plot of the system to determine the solution
The shaded area in the plot represent the solution to the inequality
In this case, one of the coordinates in the shaded area has a coordinate of (0, 5)
None of the options represent the shaded area (see attachment)
