Answer: 3,347 pounds
Step-by-step explanation:
Curb weight is simply the weight of a car with no passengers, cargo, or anyting other than the standard base model options.
Basically it's the weight of a base model car sitting on the dealership lot. Curb weight would be different if ANYTHING is added to the base model car such as a passenger, any cargo, or any upgrades aftermarket or otherwise.

Which of the following variables could theoretically be measured on a continuous scale? (a) Method of contraception used (b) length of time of residence in a state (c) task completion time (d) intelligence (e) authoritarianism (f) alienation (g) county of residence.
The variable that could theoretically be measured on a continuous scale is task completion time.
Task completion time is the duration between the initiation and completion of a specific task. It is continuous as it can take a large range of values on a continuous scale without any gap. It is frequently calculated in various businesses and researches to determine the efficiency and productivity of a particular task or process.
The other variables, such as method of contraception used, length of time of residence in a state, intelligence, authoritarianism, alienation, and county of residence, are all discrete variables. These variables take non-numerical values and are separate from each other by a gap.
These variables can be classified and counted into different categories, such as the number of individuals using a particular method of contraception, number of years of residence in a particular state, number of individuals belonging to a particular county, or number of individuals showing authoritarianism.

To determine the confidence level chosen, we need to consider the properties of a confidence interval. In this case, the confidence interval is given as[tex]$[259.32; 260.68]$[/tex], which represents an interval estimate for the population mean.
A confidence interval is typically written as [tex]\bar{x} \pm E$,[/tex]where [tex]$\bar{x}$[/tex] is the sample mean and E is the margin οf errοr. The margin οf errοr depends οn the sample size, standard deviatiοn, and the desired level οf cοnfidence.

Answer:
Step-by-step explanation:
5- There are 2 right-angled triangles and 1 equilateral triangle or you can just say triangles
6- area for a triangle is a=bh(1/2)
so 4×3=12(1/2)=6
and 4×3=12(1/2)=6
In both triangles, they're a=6
7- 4×6=24(1/2)=12
the top flag is a=12
8-12+6+6=24
9- the rectangular flag has an area of 24 since a=bh and the added areas of the triangles are 24. I conclude that these are two ways of finding the area of this rectangular flag.

The driveshaft lifespan is measured in operating hours before failure, and the distribution of lifespans is known to follow a Gamma distribution. A sample of 50 driveshafts is carefully tracked until failure and their lifespans are measured to have sample mean of 1274 hours, and a standard deviation of 108 hours.
(a)Assuming a normal distribution with the mean and standard deviation of the sample, estimate the proportion of driveshafts that would fail prior to reaching 1200 operating hours.
(b)Using the central limit theorem and corresponding normality assumption, calculate a 95% confi- dence interval for the true mean lifespan.
a. The estimated proportion of driveshafts that would fail prior to reaching 1200 operating hours is approximately 0.246, or 24.6%.
b. The 95% confidence interval for the true mean lifespan is approximately (1244.79, 1303.21) hours.
How to calculate the value(a) First, we need to standardize the value 1200 using the sample mean and standard deviation. We calculate the z-score as follows:
z = (x - μ) / σ,
z = (1200 - 1274) / 108
≈ -0.685
Using a standard normal distribution table or calculator, we find that the proportion is approximately 0.246.
(b) The formula for the confidence interval is:
CI = x ± z * (σ / √n),
CI = 1274 ± 1.96 * (108 / √50)
CI = 1274 ± 1.96 * (108 / √50)
CI ≈ 1274 ± 1.96 * 15.297
The 95% confidence interval for the true mean lifespan is approximately (1244.79, 1303.21) hours.

Triangle ABC is an isosceles triangle where angles angle A and B are congruent of angle B measures 35 what is the measurement of angle c
Answer:
m<C = 110
Step-by-step explanation:
<a = <b
<b = 35 so,
<a = 35
<c = x
<a + <b + <c = 180
35 + 35 + x = 180
70 + x = 180

To find out on which interval are both functions f(x) = x^2 + 2x and g(x) = log (2x + 1) negative, we need to analyze the intervals of negative values of both functions.
We can plot their graphs to have a better understanding:
Graphs of f(x) = x² + 2x and g(x) = log(2x + 1)
Now, we need to observe the intervals where both functions lie below the x-axis: The function f(x) = x^2 + 2x is below the x-axis on the interval (-∞, -2).
The function g(x) = log(2x + 1) is below the x-axis on the interval (-1/2, 0).
Therefore, the interval on which both functions are negative is (-2, 0).Thus, the correct option is (–2, 0).

The lenght of an arc in a circle with radius 8 inches is 3.2π. determine the measure of the arc
Answer:
72
Step-by-step explanation:
32pi×360/2pi(8)=72
central angle= arc length 360/2pi×r
The measure of the arc is 72 degree
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
The measure of the arc, we use the formula:
⇒ Arc length = (angle measure / 360°) x 2πr
where r is the radius of the circle.
Now, We know that;
The radius is 8 inches, and that the arc length is 3.2π inches.
So, we can plug in those values and solve for the angle measure:
3.2π = (angle measure / 360°) x 2π(8)
3.2π = (angle measure / 360°) x 16π
Divide both sides by 16π:
0.2 = angle measure / 360°
Multiply both sides by 360°:
Angle measure = 72°
Thus, The measure of the arc is 72 degree

Find the area under the standard normal distribution curve between z=0 and z=0.25. Use The Standard Normal Distribution Table and enter the answer to 4 decimal places.
The area between the two z values is ______
The area under the standard normal distribution curve between z=0 and z=0.25 is 0.0987.
First cumulative probability = z = 0 and
Second cumulative probability = z = 0.25
The Standard Normal Distribution Table, often known as the Z-table, may be used to determine the area under the standard normal distribution curve between z=0 and z=0.25. The table shows the total likelihood (area) up to a specified z-value. The cumulative probability, which can be found by looking up the z-value of 0 in the table, is 0.5000. The cumulative probability is 0.5987 when we look up the z-value of 0.25.
Calculating the area -
Area = First cumulative probability - Second cumulative probability
= 0.5987 - 0.5000

How much interest is earned on a principal of $316 invested at an interest rate of 9%
compounded annually for four years?
Answer:
$130.06
Step-by-step explanation:
Interest is calculated as shown;
I = A - P
A is the amount
P is the principal
Given
Principal = $316
Rate R = 9% = 0.09
Time t = 4yrs
Substiutte and get Amount A
A =P(1+r)^n
A = 316 (1+0.09)^4
A = 316(1.09)^4
A = 316(1.4116)
A = 446.06
Interest = 446.06 - 316
Interest = 130.06
Hence the interest is $130.06

The system in the requested form, using prime notation for derivatives and ï notation for variables, is ï' = e^2tï - 8tï' + 7sin(t) and ï'' = 2tan(t)ï' + 7ï - 2cos(t).
The system can be written in the form:
x' = e^2tx - 8ty + 7sin(t)
y' = 2tan(t)y + 7x - 2cos(t)
Using prime notation for derivatives, the system becomes:
x' = e^2tx - 8ty + 7sin(t)
y' = 2tan(t)y + 7x - 2cos(t)
Furthermore, we can write x and y using ï' notation as:
x = ï
y = ï'
Substituting these expressions into the system, we have:
ï' = e^2tï - 8tï' + 7sin(t)
