A line segment has an endpoint at (-7, 11) and (-6, 4), what is the length of
the segment?

Answer:

a). t = 5 years.

b). n = 25000 words.

Step-by-step explanation:

From the question it have been given a formula

which is n = 2450t + 500

a) The year

n = 12750 words

n = 2450t + 500

= 12750 = 2450t + 500

= 12750 - 500 = 2450t

= 12250 = 2450t

= 12250/2450 = 2450t/2450.

5 years = t

Or

t = 5 years.

b). The words

t = 10 years

= n = 2450t + 500

= n = 2450(10) + 500

= n = 24500 + 500

n = 25000 words.

a. To subtract like terms, subtract the coefficients, not the variables b. Like terms are terms that contain the same variable e. Negative (negative x) is equivalent to Negative x, so Negative 5 x minus x = negative 6 x.

The expression can be made simpler by using these facts.

We may take the coefficients of the similar terms, which are x and -x, out using fact a. In this instance, the expression is simplified to read as Negative 5 x minus x = Negative 6 x.

According to fact b, terms that have the same variable raised to the same power are referred to as being like terms. As we can see, there are two like terms—Negative y and -2y—in this situation that can be joined. The similar terms' coefficients, which are -1 and -2, can be added. The total is y-3.

Negative (negative x) is equal to negative x, according to Fact e. We can see that Negative 5 x is Negative (negative x) in this situation and can be reduced to Negative 6 x.

Therefore, Negative 6 x -3 y + 3 z would be the abbreviated expression.

Due to the fact that fact C's computation does not use the same simplified formulation as the other facts, it is important to note that fact C is incorrect.

Answer:

Out of all possible choices you've shown, I'd say the best answer would be A

Step-by-step explanation:

If the bumper is at -1.6 units and It is programmed to move -2.3units. The bumper should be placed at -3.9 units

The location of the bumper is calculated by the concept of addition that takes place when the two values has negative signs values.

The negative numbers are located by the left of zero on the number line. The two points are both negative and have the value of -1.6 units and -2.3 units

Summing the two units together will result to

a. The probability that the sample proportion will be within ±0.03 of the population proportion is 0.6456.
b. The probability that the sample proportion will be within ±0.03 of the population proportion is 1.985.

What is population proportion?
The probability that a specific event will occur in the population is known as the population proportion. It is a parameter, and the sample proportion statistic is used to estimate it. The percentage of occurrences that occur in the sample is known as the sample proportion.

a. The probability that the sample proportion will be within ±0.03 of the population proportion is P(-0.03 < p‌ - P < 0.003).
We Know that z-score of sample proportion is given by:
z = (p‌ - P)/SE(p‌), where SE(p‌) represents standard error.
⇒SE(p‌) = √(0.3 * 0.7)/200
⇒SE(p‌) = √0.00105
⇒SE(p‌) = 0.0324

Now, using the z score, the probability P(-0.03 < p‌ - P < 0.003) is computed as follows:
P(-0.03 < p‌ - P < 0.003) = P(-0.03/SE(p‌) < p‌ - P/SE(p‌) < 0.003/SE(p‌))
= P(-0.03/0.0324 < Z < 0.003/0.0324)
= P(−0.925926 < Z < 0.925926)
= 2P(0 < Z < 0.925926)


P(0 < Z < 0.925926) = 0.3228   (Using standard table)
So,
2P(0 < Z < 0.925926) = 2*0.3228 = 0.6456
Hence, the probability that the sample proportion will be within ±0.03 the population proportion is 0.6456.


b. The probability that the sample proportion will be within ±0.03 of the population proportion is P(-0.08 < p‌ - P < 0.008).
Also, SE(p‌) = 0.0324
Now, using z score,
P(-0.08 < p‌ - P < 0.008) = P(-0.08/SE(p‌) < p‌ - P/SE(p‌) < 0.008/SE(p‌))
= P(-0.08/0.0324 < Z < 0.008/0.0324)
= P(−2.469135 < Z < 2.469135)
= 2P(0 < Z < 2.469135)

P(0 < Z < 2.469135) = 0.9925   (Using standard table)
So,
2P(0 < Z < 2.469135) = 2*0.9925 = 1.985

Hence, the probability that the sample proportion will be within ±0.03 of the population proportion is 1.985.

The angles of the triangle KHP are P ≈ 118.555°, H ≈ 34.614°, K ≈ 26.844°, respectively.

Here we have the case of a triangle where the lengths of three sides are known and measures of angles must be determined. The missing angles can be found by means of law of cosine, whose equations related to the triangle are introduced below;

p² = h² + k² - 2 · h · k · cos P

h² = p² + k² - 2 · p · k · cos H

k² = h² + p² - 2 · h · p · cos K

Given;

h, k, p - Sides

H, K, P - Angles

If we know that h = 16.1, p = 24.9 and k = 12.8, then the measures of the angles are;

cos P = (p² - h² - k²) / (- 2 · h · k)

cos P = (24.9² - 16.1² - 12.8²) / (- 2 · 16.1 · 12.8)

cos P = - 0.478

P ≈ 118.555°

cos H = (h² - p² - k²) / (- 2 · p · k)

cos H = (16.1² - 24.9² - 12.8²) / (- 2 · 24.9 · 12.8)

cos H = 0.823

H ≈ 34.614°

cos K = (k² - h² - p²) / (- 2 · h · p)

b) By leasing the car instead of purchasing it outright, the customer will save $14,760.

c) The lease options for the lessee after returning the car include:

A lease is a financing option for the use of capital assets.

With a lease, the lessee uses the asset for a specific period and the lessor receives periodic payments.

There are operating and finance (capital) leases.  Though, under new accounting standards, all leases are to be classified as finance leases.

Value of the car = $32,000

Harmonized Sales Tax (HST) = 13%

Cost of the car with HST = $36,160 ($32,000 x 1.13)

Down payment = $1,000

Financing part = $35,160 ($36,160 - $1,000)

Installment payments = 48

Finding an inverse, swap x and y

[tex] \displaystyle{x = \sqrt[3]{y- 1} + 4}[/tex]

The ratio of all potential cases to the number of cases that are favorable to an event determines its likelihood when there is no reason for us to believe that any one of these circumstances will happen more frequently than any other, making them all equally likely.

The likelihood that an event will occur is quantified by probability. The probability of an event is the relative frequency throughout time of that event. Probabilities are all numbers between 0 and 1, inclusive—that is, any numbers between 0 and 1.

Analyzing the coordinates being provided, the scale factor is found to be 0.5, hence the image of point A(12,4) under the same dilation and the center of dilation as origin is A'(6,2).

A dilation is a transformation in Euclidean space that enlarges or reduces all the points in a figure by a scale factor. In the example given, the dilation maps (6, 10) to (3, 5) with a scale factor of 0.5, and the center of dilation is the origin (0,0). The image of a point A(x,y) under this dilation would be A'(x*0.5, y*0.5). It means the point is scaled down by 0.5 in both x and y coordinate.

The dilation described above can be used in real-world applications such as image processing, where it can be used to reduce the size of an image without losing important details, or to enlarge an image without introducing distortion. It can also be used in architectural design to create smaller or larger versions of floor plans and blueprints. Additionally, it can be used in cartography to change the scale of maps without altering the shape of the features on the map.

Analyzing the given dilation map , mapped from (6,10) to (3,5) ,the center of the dilation being origin. We can see that the scaling factor is 0.5.
