Based on the survey results, approximately 1626 households out of the 2541 households surveyed own one car.

To determine the number of American households that own one car based on the survey results, we can use the following calculation:

Number of households owning one car = (Percentage of households owning one car / 100) * Total number of households

Given that the survey discovered that 64% of households own one car and the total number of households surveyed is 2541, we can calculate:

Number of households owning one car = (64 / 100) * 2541

= 0.64 * 2541

Answer: 49.4

Step-by-step explanation: a squared plus b squared equals c squared formula

To sketch the area represented by g(x) = x ∫(from 1 to 4) t^4 dt, we need to evaluate the integral first.

g(x) = x ∫(from 1 to 4) t^4 dt

g(x) = x [t^5/5] (from 1 to 4)

g(x) = x [(4^5/5) - (1^5/5)]

g(x) = x (102.4 - 0.2)

g(x) = 102.2x

So, g(x) is a linear function of x with a slope of 102.2 and y-intercept of 0. To sketch the area represented by g(x), we can draw a straight line passing through the origin (0, 0) with a slope of 102.2. The area represented by g(x) is the shaded region between this line and the x-axis, bounded by the vertical lines x = 1 and x = 4.

Here's a sketch of the area represented by g(x):

The shaded region represents the area under the curve of the function g(x) = x ∫(from 1 to 4) t^4 dt, between x = 1 and x = 4. The area increases as x increases, because g(x) is a linear function with a positive slope.

The volume V of a cube with side length x is given by:

V = x^3

We want to find how fast the side length x is changing with respect to time, or dx/dt, when x = 3, given that the volume is increasing at a rate of 2 ft^3/min. This can be found using the chain rule of differentiation:

dV/dt = d/dt(x^3) = 3x^2(dx/dt)

Rearranging, we get:

dx/dt = (1/3x^2)(dV/dt)

Substituting x = 3 and dV/dt = 2 ft^3/min, we get:

dx/dt = (1/3(3)^2)(2 ft^3/min) = (2/27) ft/min

Therefore, when the side length of the cube is 3 feet and the volume is increasing at a rate of 2 ft^3/min, the side length is changing at a rate of (2/27) ft/min.

Answer:  When x = 3 ft, the side length of the cube is changing at a rate of 2/9 ft/min.

Step-by-step explanation:

The volume of a cube with side length x is given by V = x^3.

We are given that the volume V is changing with respect to time t at a rate of 2 ft^3/min. We want to find the rate of change of the side length x with respect to time when x = 3.

Using the chain rule, we have:dV/dt = d/dt(x^3) = 3x^2 (dx/dt)We can solve for dx/dt:dx/dt = (1/3x^2) dV/dtWhen x = 3, the volume of the cube is V = (3 ft)^3 = 27 ft^3. Therefore, dV/dt = 2 ft^3/min.

Substituting x = 3 and dV/dt = 2 into the equation above, we get:dx/dt = (1/3(3^2)) (2) = 2/9 ft/min

Therefore, when x = 3 ft, the side length of the cube is changing at a rate of 2/9 ft/min.

Solving for x, we get x = 9.

Step-by-step explanation:

The area of the required shaded region is 2.26 cm²

Given is a circle of radius 5 cm having a central angle of 60°,

We need to find the area of the shaded region,

So, we will find it by subtracting the area of the triangle from the sector having a central angle of 60°,

Since one angle is 60° in the triangle so the triangle is an equilateral triangle with side 5 cm,

Area of an equilateral triangle = √3/4 × side²

= √3/4 × 5²

= 10.82 cm²

Now the area of the sector = central angle / 360° × area of the circle

= 60° / 360° × 3.14 × 5²

= 13.08 cm²

Now the area of the shaded region = 13.08 - 10.82 = 2.26 cm²

On ne sait pas combien de morceaux de musique ont été téléchargés, il n'est donc pas possible de calculer le coût total exact. Cependant, nous pouvons déterminer à partir de quel nombre de morceaux le forfait n2 devient plus avantageux que le forfait n1.

Le coût total du forfait n1 est de 0,9 euros par morceau téléchargé, alors que le coût total du forfait n2 est de 24 euros plus 0,5 euros par morceau téléchargé. Nous pouvons donc écrire l'équation suivante pour comparer les deux forfaits :

0,9x = 24 + 0,5x

Answer:

Step-by-step explanation:

Since line segment EF is parallel to line segment BD, we can use the property that corresponding angles are congruent to set up the following proportion:

EF/BD = FL/BC

Substituting the given values:

EF/4 = 5/12

Cross-multiplying:

EF = 4 x 5/12 = 5/3 cm

We can use the fact that triangles BCD and EFD are similar (having two congruent angles) to set up another proportion:

CD/EF = BC/BD

Substituting the given values:

CD/(5/3) = 12/BD

Solving for CD:

CD = (5/3) x 12/BD = 20/BD cm

We can use the Pythagorean theorem to find the length of BD:

BD^2 = BC^2 + CD^2

Substituting the given values:

BD^2 = 3^2 + 12^2 = 153

Taking the square root of both sides:

BD = sqrt(153) = 3sqrt(17) cm

Substituting this value into the expression for CD:

CD = 20/BD = 20/(3sqrt(17)) = (20/3)sqrt(17) cm

Therefore, the length of line segment CD is (20/3)sqrt(17) cm.

For the study of trucker drives, the 99% confidence interval of the mean number of miles driven per day by all truckers is equals to the (−531.74,548.26).

The one way to estimate the population mean is the confidence interval. The interval consists of a point estimate and a margin of error for the estimate. We have a sample of study of truckers,

Mean of miles = 540

Sample size, n = 90

Step-by-step explanation:

This is an inverted parabola.

The maximum value occurs at x exactly in between the 2 zeros of the function.

y = -x^2 + 78x - 543

-x^2 + 78x - 543 = 0

x^2 - 78x + 543 = 0

x = [-(-78) ± √[(-78)^2 - 4(1)(543)]/[2(1)]

x = [78 ± √(6084 - 2172)]/2

x = 70.272  or  x = 7.727

Midpoint of the zeros:

(70.272 + 7.727)/2 = 39

Maximum profit occurs at x = 39.

f(39) = -(39)^2 + 78(39) - 543

f(39) = 978

To find P(U U V), we can use the inclusion-exclusion principle which states that the probability of the union of two events U and V is given by P(U U V) = P(U) + P(V) - P(U ∩ V).
Using the given information, we have:
P(UC) = 0.2
P(V) = 0.7
P(UUVC) = 0.3
From P(UC) = 0.2, we know that the probability of the complement of U is 0.2. Therefore, P(U) = 1 - P(UC) = 0.8.
Using the formula P(UUVC) = P(U) + P(V) - P(U ∩ V), we can rearrange to get:
P(U ∩ V) = P(U) + P(V) - P(UUVC)
P(U ∩ V) = 0.8 + 0.7 - 0.3
P(U ∩ V) = 1.2

Since AC is the hypotenuse of the right triangle ABC, we can use the Pythagorean theorem to find its length. Let's assume the other two sides of triangle ABC are a and b, with AC as the hypotenuse:

AC^2 = a^2 + b^2

Given that DC = 2, we can express a in terms of b:
