what is a chart or graph that presents grouped data with rectangular bars with lengths proportional to the values that they represent?

Answer:

Step-by-step explanation:

density = mass/volume

density = 3g/0.5cm^3 = 3x2g/cm^3=6g/cm^3

Answer:

6g/cm^3

Step-by-step explanation:

P = m/v

P = density

m = mass = 3g

v = volume = 0.5cm^3

3/0.5 = 6

A) m = (y2-y1)/(x2-x1)

m = (4-1)/(-2-(-3))

m = 3/1

m = 3

B) point slope equation : y-y1=m(x-x1)

y - 4 = 3 ( x + 2 )

C) slope intercept equation: y = mx + c

4 = 3(-2) + c

4 = -6 +c

c = 10

Thus, the equation is y= 3x + 10

The equation of the plane parallel to 5x - y - z = 6 and passing through (1, -1, -1) is 5x - y - z = 7.

The equation of the plane that passes through (1, -1, -1) and is parallel to the plane 5x - y - z = 6 can be written as 5x + y + z = k, where k is a fixed number or constant.

To find the value of k, we substitute the coordinates of the given point (1, -1, -1) into the equation of the plane:

5(1) - (-1) - (-1) = k

5 + 1 + 1 = k

7 = k

Therefore, the equation of the plane parallel to 5x - y - z = 6 and passing through (1, -1, -1) is 5x - y - z = 7.

Answer:

111 miles

Step-by-step explanation:

First, we need to find out how far the cheetah goes if the lion goes 1 mile.

74/50=1.48

So, if the lion goes 1 mile, the cheetah goes 1.48 miles. If the lion goes 75 miles, we must multiply it by how far the cheetah goes.

75*1.48=111 miles

I hopw this helped! Tell me if you have any questions about this :)

Sighe speed - distance relation, the cheetah will cover a distance of 111 miles in the same time.

Lion :

Speed = 50 mph

Time taken to cover 75 miles

Time taken = Distance / speed

Time taken = 75 / 50 = 1.5 hours

CHEETAH :

Speed = 74 mph

Time taken = 1.5 hours

Distance covered in 1.5 hours

Distance = speed × time

Distance covered = 1.5 × 74 mph = 111 miles

Therefore, the cheetah will cover a distance of 111 miles in the same time.

Answer:

x = -9

Step-by-step explanation:

The top angle would be 90 degrees due to the square.

The angles of a triangle add up to 180 degrees.

Set up the equation:

90 + 45 + x + 54 = 180

189 + x = 180

Subtract 189 from both sides:

x = -9

Now, if you need to solve for the angle, just plug x in:

-9 + 54 = 45 degrees

(In your case it is just looking for x so it would be x = -9)

Step-by-step explanation:

polynomial function is as follows:

we get: f(x) = -3/4x² + 27/4

Given the information about the graph of a polynomial function is as follows:

y-intercept is (0,9)

The x-intercepts are (-3, 0), (3,0)

Degree is 2

End behavior: as x → -∞, f(x) → -∞, as x → ∞, f(x) → -∞The standard form of a quadratic function is f(x) = ax² + bx + c, where a, b, and c are real numbers and a ≠ 0.

The degree of the function is given to be 2, which means that the leading coefficient is a quadratic polynomial, and it has at least one x-intercept.

The leading coefficient is assumed to be 1 or -1 since it is not given.

Let's determine the quadratic function using the given intercepts:

When x = 0, y = 9. Therefore, the constant term in the quadratic function is c = 9.

The x-intercepts are (-3, 0) and (3, 0).

Thus, (x + 3) and (x - 3) are factors of the quadratic function.

Therefore, the quadratic function is in the form off

(x) = a(x + 3)(x - 3) + 9

We can substitute one of the points to determine the value of the leading coefficient.

Substituting the point (3, 0), we have: 0 = a(3 + 3)(3 - 3) + 9

Simplifying the equation, we get: 0 = 12a + 9a = -3/4

The quadratic function is:

f(x) = -3/4(x + 3)(x - 3) + 9

Multiplying the terms and collecting like terms, we get:

f(x) = -3/4x² + 27/4

Answer:

15 feet: 30 divided by 2 is 15

Step-by-step explanation:

A the answer is a your welcome

Doug's optimal amount of Y is 75 units found using the utility function.

The optimal amount of Y for Doug is 75 units as per his utility function, u(X, Y) = X + ln Y.

The price of good X is $1 and the price of good Y is $2 and Doug has an income of $150 to spend.

Doug's aim is to maximize his utility subject to his budget constraint.

Let X and Y be the number of units of goods X and Y that Doug purchases respectively.

Then we can write Doug's utility function as:u(X, Y) = X + ln Y

The total amount that Doug spends is:

PₓX + PᵧY = $150

where Pₓ and Pᵧ are the prices of X and Y respectively.

Substituting Pₓ = $1, Pᵧ = $2 and solving for X, we get:

X = $150 - 2Y

Since we want to maximize Doug's utility function, we differentiate it with respect to Y and set it equal to zero, i.e.,

du(X, Y)/dY = 0

Differentiating u(X, Y) = X + ln Y with respect to Y gives:

du(X, Y)/dY = 1/Y

Therefore, at the optimal level of Y, we have:

1/Y = 0

Solving for Y, we get:

Y = 1/0 which is undefined.However, we know that Doug's budget constraint has to hold, i.e.,

PₓX + PᵧY = $150.

Substituting Pₓ = $1 and Pᵧ = $2, we get:

X + 2Y = 150

Substituting X = $150 - 2Y in the above equation and solving for Y gives:

150 - 2Y + 2Y

= 150Y

= 150/2Y

= 75

Therefore, Doug's optimal amount of Y is 75 units.

We are told in the question that:

Carolina goes to a paintball field that charges an entrance fee of $18 and $0.08per ball. The field has a promotion that says, "Get $10 soff if you spend $75more!"

Hence, our inequality equation is:

Let us represent the number of balls as B

$18 +0.08 × B ≥$75

18 +0.08B ≥75

0.08 ≥ 75 - 18

Answer:

20 seconds

Step-by-step explanation:

Given the following :

Alarm 1 (goes off every 10 seconds)

Alarm 2 (goes off every 5 seconds)

Alarm 3 (goes off every 4 seconds)

If they all go off now, how long will it take all to go off at the same time again.

Obtain the multiples of the time in seconds in which each alarm goes off and select the lowest multiple common to all three;

Multiples of 10 : 10, 20, 30, 40, 50,...

Multiples of 5 : 5, 10, 15, 20, 25, 30, 35, 40,...

Multiples of 4 : 4, 8, 12, 16, 20, 24, 28, 32, 36,....

Hence, the lowest multiple common to all three alarm times is 20.

Hence, all three alarms will go off at the same time again after 20 seconds

The equivalent units of production for the period is 80,000

The equivalent units of production for the period can be calculated by considering the units that were completed and transferred, as well as the units in the ending work in process. In this case, 75,000 units were completed and transferred, and there were 10,000 units in the ending work in process that were 50% complete as to materials and conversion costs.

To determine the equivalent units of production, we need to account for the work done on the units in the ending work in process. Since these units are 50% complete as to both materials and conversion costs, we can treat them as half complete units. Therefore, the equivalent units for the ending work in process would be 10,000 units multiplied by 0.5, which equals 5,000 equivalent units for both materials and conversion costs.

Adding the equivalent units from completed and transferred units (75,000) to the equivalent units from the ending work in process (5,000) gives us a total of 80,000 equivalent units of production for the period.

In summary, the equivalent units of production for the period is 80,000. This includes 75,000 equivalent units from completed and transferred units and 5,000 equivalent units from the ending work in process that were 50% complete as to materials and conversion costs. Therefore, the correct answer is option c. 80,000.

The function that describes the sequence 4, −2, 1, −1, ... , 41 is given by:an = 10 - 6n.

The sequence 4, −2, 1, −1, ... , 41 is an arithmetic sequence, which means that the difference between each consecutive term is constant. To find the common difference,

we can subtract any two consecutive terms in the sequence. Let's use the first two terms as an example: −2 − 4 = −6. We can see that the common difference is −6.

Thus, the nth term of the sequence can be expressed as follows:an = a1 + (n - 1)dwhere an represents the nth term of the sequence, a1 represents the first term of the sequence, and d represents the common difference.

In triangle PQR, with PQ = 6, PR = 10, and angle PQR = 90°, we need to find the length of QR rounded to one decimal place which is approximately 11.7 units.

To find the length of QR, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, PQ and PR are the two sides, and QR is the hypotenuse. Given that PQ = 6 and PR = 10, we can calculate the length of QR.
Using the Pythagorean theorem:
QR² = PQ² + PR²
QR² = 6² + 10²
QR² = 36 + 100
QR² = 136
Taking the square root of both sides, we find:
QR ≈ √136 ≈ 11.66
Rounded to one decimal place, the length of QR is approximately 11.7.
Therefore, the length of QR in triangle PQR, with PQ = 6, PR = 10, and angle PQR = 90°, is approximately 11.7 units.

(i) The marginal propensity to consume (MPC) is 0.8.

(ii) The marginal propensity to save (MPS) is 0.2.

(iii) The level of consumption is $360.

(iv) The average propensity to consume (APC) is 0.9 or 90%.

(v) The level of savings is $40.

The given linear equation for consumption, C = $40 + 0.8Y, and the income (Y) is $400, let's calculate the following:

(i) The marginal propensity to consume (MPC):

The marginal propensity to consume represents the change in consumption resulting from a change in income. It is the coefficient of the income term in the consumption function.

MPC = ∆C / ∆Y = 0.8

(ii) The marginal propensity to save (MPS):

The marginal propensity to save represents the change in savings resulting from a change in income. It is equal to 1 minus the marginal propensity to consume.

MPS = 1 - MPC = 1 - 0.8 = 0.2

(iii) The level of consumption when income (Y) is $400:

Plug the given income value into the consumption function.

C = $40 + 0.8Y = $40 + 0.8 * $400 = $40 + $320 = $360

Therefore, the level of consumption when income is $400 is $360.

(iv) The average propensity to consume (APC):

The average propensity to consume represents the proportion of income that is spent on consumption. It is calculated by dividing consumption by income.

APC = C / Y = $360 / $400 = 0.9

Therefore, the average propensity to consume is 0.9 or 90%.

(v) The level of savings:

Savings (S) is the difference between income (Y) and consumption (C).

S = Y - C = $400 - $360 = $40

Therefore, the level of savings is $40.
