The appropriate hypothesis test is a two-sample t-test for independent samples.

The appropriate hypothesis test in this scenario is a two-sample t-test for independent samples. Since the population standard deviations are known, we can use the Z-test instead.

The test statistic can be calculated using the formula:

t = (x1 - x2) / sqrt((s1^2 / n1) + (s2^2 / n2))

Where:

x1 and x2 are the sample means for Manufacturer A and Manufacturer B, respectively.

s1 and s2 are the population standard deviations for Manufacturer A and Manufacturer B, respectively.

n1 and n2 are the sample sizes for Manufacturer A and Manufacturer B, respectively.

Plugging in the given values:

x1 = 179, x2 = 178, s1 = 1, s2 = 5, n1 = n2 = 108

t = (179 - 178) / sqrt((1^2 / 108) + (5^2 / 108))

t = 1 / sqrt(0.00926 + 0.0463)

t ≈ 1 / sqrt(0.05556)

t ≈ 1 / 0.2357

t ≈ 4.241

To determine whether there is sufficient evidence to support the claim that the voltage of the batteries made by the two manufacturers is different, we compare the calculated t-value to the critical value from the t-distribution at the desired significance level (0.05).

The decision depends on the degrees of freedom for the test, which is calculated as (n1 + n2 - 2) = (108 + 108 - 2) = 214.

Using a t-table or statistical software, we find that the critical value for a two-tailed test with a significance level of 0.05 and 214 degrees of freedom is approximately ±1.972.

Since the calculated t-value of 4.241 exceeds the critical value of 1.972, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the voltage of the batteries made by the two manufacturers is different at the 0.05 significance level.

Answer:

\(\frac{0}{5}\) or zero.

Step-by-step explanation:

The pair on the left is (-4, -5). The pair on the right is (1, -5).

In order to find the slope, you must first subtract the y in the first pair by the y in the second pair. Then what ever answer you get will be your numerator. Then, subtract the x in the second pair by the x in the first pair and that will be your denominator. So, in this case, it would be \(\frac{-5 - -5}{1 - -4}\) which equals  \(\frac{0}{5}\). If a zero is the numerator, that means that the fraction is zero. If the zero had been on the bottom, then the answer would have been undefined.

In short the formula to find slope is: \(y^{2}\)- \(y^{1}\) over \(x^{2}\) - \(x^{1}\).

Answer:

51 square units

Step-by-step explanation:

Area of a parallelogram = base x height

⇒ area = 4 x 3 = 12 square units

Area of a rectangle = width x length

width = √(2² + 3²) = √13

length = √(9² + 6²) = √117

area = √13 x √117 = 39 square units

Total area = 12 + 39 = 51 square units

Step-by-step explanation:

The equation already gives the answer as the equation is in slope-intercept form.

\(y = mx + b\)

Where m = slope and b = y-intercept.

From the equation —

\(y = \frac{1}{3} x - 4 \\ m = \frac{1}{ 3} \\ b = - 4\)

Therefore, our slope is 1/3 and y-intercept is - 4.

Distance traveled after toll payment is 1.2 miles on highway 40.

The distance may be calculated using a curved route. Displacement measurements can only be made along straight lines. Distance is path-dependent, meaning it varies depending on the direction followed. Displacement simply depends on the body's beginning and ending positions; it is independent of the route.

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.

The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The entire length of the journey taken between two points is known as the distance traveled. Travel distance is not a vector.

The APY for super apple sauce APY is 13.4%, markers inc APY is 37.9%. The total return for super apple sauce is 137%, markers inc is 400%.

Interest refers to the amount of money that is charged or earned in relation to a principal amount of money.

To calculate the APY (annual percentage yield) for each investment, we need to use the following formula:

APY = (1 + r/n)^n - 1

1) For Super Apple Sauce, the return is $135 for every $57 invested in 5 years. Annual interest rate of:

r = (135/57)^(1/5) - 1 ≈ 0.134

Since the interest is compounded yearly, n=1. Using the formula, we get:

APY = (1 + 0.134/1)^1 - 1 ≈ 0.134 or 13.4%

Therefore, the APY for Super Apple Sauce is approximately 13.4%.

2) For Markers Inc., the return is $5 for every $1 invested in 5 years. Annual interest rate of:

r = (5/1)^(1/5) - 1 ≈ 0.379

Since the interest is compounded yearly, n=1. Using the formula, we get:

APY = (1 + 0.379/1)^1 - 1 ≈ 0.379 or 37.9%

Therefore, the APY for Markers Inc. is approximately 37.9%.

The total return for each investment:

Total Return = (Ending Value - Beginning Value) / Beginning Value

3) For Super Apple Sauce, the beginning value is $57 and the ending value is $135, so the total return is:

Total Return = ($135 - $57) / $57 ≈ 1.37 or 137%

Therefore, the total return for Super Apple Sauce is approximately 137%.

4) For Markers Inc., the beginning value is $1 and the ending value is $5, so the total return is:

Total Return = ($5 - $1) / $1 = 4 or 400%

Therefore, the total return for Markers Inc. is 400%

Answer:

The inverse is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x) = (x+3)^5

Finding the inverse,

\(f(x) = (x+3)^5\\or,\\y = (x+3)^5\)

We replace x with y and vice versa

so,

\(x = (y+3)^5\)

Solving for y,

the the 5th root,

\(\sqrt[5]{x} = y + 3\\y = \sqrt[5]{x} - 3\)

hence the inverse function is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x)=(x+3)×5

Y=5X+15

now

interxchanging x and y we get,

x=5y+15

5y=x-15

y=x-15/5

therefor f~1(x)=x-15/5

a. It represents the spread of the middle 50% of the data.

b. At least 50% of the students scored between 80 and 86.

c. Overall, we can say that the Math 6 class had a range of test scores, with some students performing very well and others performing less well.

How evenly distributed the middle 50% of the data is is determined by the interquartile range. In order to calculate it, the first quartile is subtracted from the third quartile.

A. The interquartile range (IQR) in a box-and-whisker plot is the distance between the first quartile (Q1) and the third quartile (Q3) of the data. It represents the spread of the middle 50% of the data.

B. To determine what percent of the students got 80% or higher, we need to find the upper fence, which is defined as 1.5 times the IQR above Q3. From the box-and-whisker plot, we can see that Q3 is approximately 86 and Q1 is approximately 71. Therefore, the IQR is 86 - 71 = 15. The upper fence is 1.5 * 15 + 86 = 108.5.

Looking at the plot, we can see that there are no data points above 100, so we can safely assume that no students scored above 100%. The highest score is 94, which is within the whiskers of the box-and-whisker plot. Therefore, we know that the percent of students who scored 80% or higher is between the percent of students who scored 80% or higher and the percent of students who scored 94% or higher.

From the plot, we can see that the median is approximately 80 and the third quartile (Q3) is approximately 86. This means that at least 50% of the students scored between 80 and 86. Additionally, we know that the maximum score is 94, so we can say that at least some students scored higher than 86. However, we don't know how many students scored between 86 and 94.

C. Based on the interquartile range, we can say that the middle 50% of the students scored between approximately 71 and 86. This suggests that there is a significant amount of variability in the test scores, as the range is quite wide. Additionally, we know that at least some students scored above 86, but we don't have enough information to determine how many or how high their scores were. Overall, we can say that the Math 6 class had a range of test scores, with some students performing very well and others performing less well.

The smallest positive debt that can be paid off using sticker trading is $7$ dollars.

To find the smallest positive debt that can be paid off using sticker trading, we need to consider the values of the stickers (in dollars) and find the smallest positive amount that can be reached through a combination of these values.

Given that a Harry Potter sticker is worth $49 and a Twilight sticker is worth $35, we can approach this problem using the concept of the greatest common divisor (GCD) of these two values.

The GCD of $49$ and $35$ is $7$. This means that any multiple of the GCD can be represented using these sticker values.

In other words, any positive multiple of $7$ dollars can be paid off using sticker trading.
