4 units

Number lines are linear representations of length or some other unit.

Number Lines

Number lines are always straight lines that only have one dimension. This means that there is only one axis or line that has values. As seen in the picture, number lines are usually drawn horizontally and marked with numbers to visually represent data.

Line of QR

The question asks for the units of QR. This notation represents the line between the 2 points Q and R. So, to find the length of the line we can simply count the distance between the two points. Between the values of -3 and 1, there are 4 units. So, the line has a length of 4 units.

We can also find the length by subtracting the two numbers.

Answer:

1.91

Step-by-step explanation:

Duncan had 3.8 and used 1.89 obviously we can't subtract right now so we have to add a 0 to 3.8 so it would 3.80 - 1.89 = 1.91

The number 713.49 is already written in standard form.

Standard form, also known as standard notation or scientific notation, is a way of writing numbers using digits and decimal places. In standard form, a number is written with one digit to the left of the decimal point and the remaining digits to the right of the decimal point.

For example, the number 7,134.9 would be written in standard form as 7,134.9. The number 713.49 is already written in this format, so there is no need to convert it to standard form.

Therefore, (b) x = -10 is the result that is a solution of the rational equation that must be ignored due to the context.

Any equation in algebra that can be written in standard form as where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation. In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler. ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem. The answer could be simple or complicated.

The bias of mu1 is 0, the variance of mu1 is 1/2, and the mean squared error of mu1 is 1/2.

We need to find the bias, variance, and mean squared error of mu1, given that x1 and x2 are independent with an unknown mean (mu) and a known variance (sigma^2 = 1), and mu1 = (x1 + x2)/2.

Step 1: Compute the expected value of mu1.
E(mu1) = E((x1 + x2)/2) = (E(x1) + E(x2))/2 = (mu + mu)/2 = mu

Step 2: Calculate the bias of mu1.
Bias (mu1) = E (mu1) - mu = mu - mu = 0

Step 3: Calculate the variance of mu1.
Var(mu1) = Var((x1 + x2)/2) = (1/4) * (Var(x1) + Var(x2)) = (1/4) * (1 + 1) = 1/2

The data supports the hypothesis that the start-up costs of the two types of businesses, specialty clothing stores and coffee houses, are significantly different at a 1% significance level.

The null hypothesis (H₀): The start-up costs of specialty clothing stores and coffee houses are equal.

The alternative hypothesis (H₁): The start-up costs of specialty clothing stores and coffee houses are different.

The significance level (α) is given as 1% or 0.01.

The test statistic for a two-sample t-test is given by:

t = (x₁ - x₂) / √[(s₁²/n₁) + (s₂²/n₂)]

Plugging in the given values:

x₁ = $92,000, x₂ = $74,000, s₁ = $24,000, s₂ = $18,000, n₁ = 15 and n₂ = 12

t = (92,000 - 74,000) / √[(24,000²/15) + (18,000²/12)]

Since the significance level is 1% (0.01), we need to find the critical value for a two-tailed test with a degree of freedom equal to (n₁ + n₂ - 2).

We can use a t-table or statistical software to find this value.

For a significance level of 0.01 and degrees of freedom (15 + 12 - 2 = 25), the critical value is approximately ±2.796.

If the absolute value of the calculated t-statistic is greater than the critical value from Step 4, we reject the null hypothesis.

Otherwise, we fail to reject the null hypothesis.

Let's calculate the test statistic:

t = (92,000 - 74,000) / √[(24,000²/15) + (18,000²/12)]

= 18,000 / √[(3,840,000/15) + (3,240,000/12)]

= 24.82

Since the absolute value of the calculated t-statistic (|24.82|) is greater than the critical value (2.796) at the 1% significance level, we reject the null hypothesis.

Answer: The lowest possible product would be -6724 given the numbers 82 and -82.

We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.

Next we'll multiply the numbers together.

x(x+164)

x^2 + 164x

Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2

-b/2a = -164/2(1) = -164/2 = -82

So we know one of the values is -82. We can plug that into the equation to find the second.

x + 164

The radius of the cone is 7 feet

The given parameters are:

Surface Area, A = 216π

h = 8/3r

The surface area of a cone is:

\(A = \pi r(r + \sqrt{h^2 + r^2})\)

So, we have:

\(216\pi = \pi r(r + \sqrt{(8/3r)^2 + r^2})\)

Factor out r

\(216\pi = \pi r(r + r\sqrt{(8/3)^2 + 1})\)

Evaluate the exponent

\(216\pi = \pi r(r + r * 2.85)\)

Evaluate the sum

\(216\pi = \pi r(3.85r)\)

Divide both sides by pi

\(216 = 3.85r^2\)

Divide both sides by 3.85

\(56.10 = r^2\)

Take the square roots of both sides

r = 7 (approximately)

Step-by-step explanation:

The correct answer is c) 0.028. The formula for margin of error for difference in proportion can be used to calculate the margin of error with a 95% confidence level.

For the provided data, the margin of error with a 95% confidence level is given by.

MOE is equal to 0.32.

Let's say we have two samples, each with a sample size of and. Let the quantities that are of interest that were discovered in those samples be determined by their respective sample sizes. After that, we can use the margin of error for proportional difference to determine the margin of error as:

\(MOE = z_{ \frac{ \alpha }{2} } \times \sqrt{ \frac{p1(1- p1)}{n1} + \frac{p(1- p2)}{n2} } \)

we get,

\(p1 = \frac{x1}{n1} \\ p2 = \frac{x2}{n2} \)

and,

\( \alpha = level \: \: of \: \: significance\)

By using the provided data to find the margin of error

Year is 2018, n1=1542, x1=415

Year is 1998, n2=1323, x2=326

\( \alpha = 100 - 95\% \\ = 1 - 0.95 \\ = 0.05\)

For 95% confidence, we have Z score as 1.96

The proportions are calculated as:

\(p1 = \frac{415}{1542} = 0.269 \\ p2 = \frac{326}{1323} = 0.245\)

Therefore, margin of error can be calculated:

\(MOE = 1.96 \times \sqrt{ \frac{0.269 \times 0.731}{1542} } + \frac{0.245 \times 0.754}{1323} \\ = 1.96 \times 0.000139\\ = 0.028\)

b) {(33), (39)}: This is possible. Transaction T1 updates the value from 3 to 9, and then T2 updates it from 9 to 39.

c) {(3), (9)}: This is possible. Transaction T1 updates the value from 1 to 3, and then T2 updates it from 3 to 9.

d) {(13), (19)}: This is possible. Transaction T1 updates the value from 1 to 3, and then T2 updates it from 3 to 13, and finally, T1 updates it again from 13 to 19.

e) {(33), (19)}: This is not possible. Transaction T1 updates the value from 1 to 3, and then T2 updates it from 3 to 13. Therefore, T1 cannot update it from 13 to 19 since the value is already 13.

f) {(11), (13)}: This is possible. Transaction T2 updates the value from 1 to 11, and then T1 updates it from 11 to 13.

g) {(11), (19)}: This is not possible. Transaction T2 updates the value from 1 to 11, and then T1 cannot update it from 11 to 19 since the value is already 11.

When a data value is converted to a standardized scale representing the number of standard deviations the data value lies from the mean, we call the new value a Z-Score.

In statistics, each mathematical formula and each element has an internationally recognised name. This is to ensure that everyone in the world understands what every researcher has to say in every letter. A statistic that tells the number of standard deviations a data value is above or below the mean is called a z-score. And its formula is, Z = (X − μ)/σ

where, μ--> population mean,

σ --> population standard deviation and

x --> the raw-score.

Hence, when a data value is converted to a standardized scale, new value, Z-Score is representing the number of standard deviations the data value lies from the mean.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

The critical points of f are x = 1 and x = 3.

Therefore, f is increasing on (-∞,1) and (3,∞), and decreasing on (1,3).

To determine where the function f is increasing or decreasing, we need to analyze the sign of its derivative f'(x).

First, let's find the critical points of f by solving f'(x) = 0:

\(f'(x) = e^(x^2 - 4x + 3) - 1 = 0\)
Taking the natural logarithm of both sides, we get:

\(x^2 - 4x + 3 = ln(1) = 0\)

which simplifies to:

(x - 1)(x - 3) = 0

Therefore, the critical points of f are x = 1 and x = 3.

Now, let's analyze the sign of f'(x) on each of the intervals (-∞,1), (1,3), and (3,∞).

On the interval (-∞,1), f'(x) is positive because \(e^(x^2 - 4x + 3) > 1\) for all x in this interval. This means that f is increasing on (-∞,1).

On the interval (1,3), f'(x) is negative because \(e^(x^2 - 4x + 3) < 1\) for all x in this interval. This means that f is decreasing on (1,3).

On the interval (3,∞), f'(x) is positive again because \(e^(x^2 - 4x + 3) > 1\) for all x in this interval. This means that f is increasing on (3,∞).

Therefore, f is increasing on (-∞,1) and (3,∞), and decreasing on (1,3).
