A square has an area of
x^2-14x + 49cm2.

What is the perimeter of the square?

The correct answer is:

(a) about 4% of the variation in y has been explained by the model.

The answer is (a) about 4% of the variation in y has been explained by the model.

The coefficient of determination (R-squared) is given as 0.03579295, which represents the proportion of the total variation in the dependent variable (calculus achievement scores) that is explained by the independent variable (algebra placement test scores) in the model.

Since R-squared is the square of the correlation coefficient (multiple R), we can also interpret the value of multiple R as the correlation between the two variables. In this case, multiple R is given as 0.18919025, indicating a weak positive correlation between the two variables.

The adjusted R-squared is negative (-0.2856094), which suggests that the model is not a good fit for the data. However, the question specifically asks for the proportion of variation in the dependent variable that is explained by the model, which is represented by R-squared. Therefore, the answer is (a) about 4% of the variation in y has been explained by the model.

The perimeter of the sector = 47.905 cm

47.905 cm is greater than 47.5 cm.

Perimeter of a sector = Arc length + 2(radius).

Arc length = ∅/360 × 2πr

Given the following:

Perimeter = (∅/360 × 2πr) + 2(r) = (135/360 × 2×π×11) + 2(11)

Perimeter = 25.905 + 22

Perimeter = 47.905 cm

Thus, the perimeter of the sector (47.905 cm) is greater than 47.5 cm.

The main difference between independent and conditional probability lies in whether the occurrence of one event affects the probability of the other event. To test for independence, you can use the formula P(A and B) = P(A) * P(B).

Independent probability refers to the probability of one event occurring without being influenced by the occurrence or non-occurrence of another event. In other words, the probability of one event happening does not affect the probability of the other event happening.

Conditional probability, on the other hand, refers to the probability of an event occurring given that another event has already occurred. It takes into account the relationship between two events and how the occurrence of one event affects the probability of the other event.

To determine if two events, A and B, are independent or dependent, you can use the formula: P(A and B) = P(A) * P(B). If the product of the probabilities of events A and B is equal to the probability of both events occurring together, then the events are independent. If the product is not equal to the probability of both events occurring together, then the events are dependent.

In conclusion, the main difference between independent and conditional probability lies in whether the occurrence of one event affects the probability of the other event. To test for independence, you can use the formula P(A and B) = P(A) * P(B).

The difference between independent and conditional probability lies in the relationship between two events. Independent probability refers to the occurrence of one event not affecting the probability of the other event. On the other hand, conditional probability refers to the probability of an event occurring given that another event has already occurred.

To determine if two events, A and B, are independent or dependent, you can use a numerical test called the product rule. The product rule states that if two events are independent, then the probability of both events occurring is equal to the product of their individual probabilities. Mathematically, this can be expressed as:
P(A and B) = P(A) * P(B)
To determine if two events are dependent, you can compare the actual probability of both events occurring together (P(A and B)) with the expected probability if the events were independent (P(A) * P(B)). If the actual probability is equal to the expected probability, the events are independent. If the actual probability is different from the expected probability, the events are dependent.
Let's consider an example to illustrate this concept. Suppose we have a deck of 52 playing cards, and we draw two cards without replacement. Event A is drawing a red card, and Event B is drawing a spade.

Answer: B. horizontal line; yes

Use the slope-intercept form to find the slope and y-intercept.

Slope:  

0

y-intercept:  

(0,0)

Yes it is a function. It is a horizontal line.  

Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.  

Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.  

Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b

m = 0 is the slope

b = 4 is the y intercept

Step-by-step explanation: A. vertical line; yes

horizontal line; yes

Yes! Horizontal line represents a function y = f(x)

(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.

(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Straight forward means direct and can be sometimes harsh.

The probability of the shorter segment being less than 14 times the longer segment is 1/15.

The line segment of length l can be divided into two segments of lengths x and y, such that x + y = l. Since the point is chosen at random, the probability of x being shorter than 14y is the same as the probability of y being longer than x/14. Since the point can be chosen anywhere along the line segment, the probability of the ratio of x to y being less than 14 is equal to the probability of x/y being less than 14, which is 1/15. Therefore, the probability of the ratio of the shorter to the longer segment being less than 14 is 1/15.

There are approximately 0.4594 acres in 2.0 hectares.

We need to use the conversion factor between hectares and acres.

Given:

\(1 hectare = 1\) × \(10^4 m^2\)

\(1 acre = 4.356\) × \(10^4 ft\)

To find the number of acres in 2.0 hectares, we can set up the following conversion:

\(2.0 hectares * (1\) × \(10^4 m^2 / 1 hectare) * (1 acre / 4.356\) × \(10^4 ft)\)

Simplifying the units:

\(2.0 * (1\) × \(10^4 m^2) * (1 acre / 4.356\) ×\(10^4 ft)\)

Now, we can perform the calculation:

\(2.0 * (1\) × \(10^4) * (1 /\)\(4.356\) ×\(10^4)\)

= 2.0 * 1 / 4.356

= 0.4594

Therefore, there are approximately 0.4594 acres in 2.0 hectares.

This can be simplified to 3^7, which equals 2,187. So, there are 2,187 different key designs possible for these antique cars.

To determine the number of different key designs possible for antique cars with seven parts and three patterns for each part, we can use the multiplication principle of counting.

This principle states that if there are m ways to perform one action and n ways to perform another action, then there are m x n ways to perform both actions together.

Therefore, the number of different key designs possible can be calculated by multiplying the number of patterns for each part together. In this case, we have three patterns for each of the seven parts, so we can calculate the number of possible designs by using the formula 3^7.

Using a calculator, we can see that 3^7 is equal to 2,187. Therefore, there are 2,187 different key designs possible for antique cars with seven parts and three patterns for each part. It's worth noting that not all of these designs may have actually been produced or used, but this calculation gives us the total number of possibilities based on the given information.
Hi! I'd be happy to help you with your question. To determine the number of different key designs possible for these antique cars, we can use the multiplication principle of counting. Since there are 7 parts to each key and 3 patterns for each part, we can multiply the number of patterns for each part together to find the total number of key designs.

The calculation would be: 3 (patterns for part 1) × 3 (patterns for part 2) × 3 (patterns for part 3) × 3 (patterns for part 4) × 3 (patterns for part 5) × 3 (patterns for part 6) × 3 (patterns for part 7).

Explanation

Because the perfume is on sale (70% off), it only costs 30% of its original price.

So we divide the sale price of the perfume ($12) by 30%

12 ÷ 30 = 0.4

Then, we multiply 0.4 by 100

Answer:

£280.0

Step-by-step explanation:

Given the following

Rate R= 4%

Time T = 1year

Amount = £291.20

Simple Interest I = ?

I = PRT/100

A = P+I

Since P = A-I

I = (A-I)RT/100

I = (291.2-I)RT/100

100I = (291.2-I)4

100I = 1,164.8-4I

104I = 1,164.8

I = 1,164.8/104

I =  £11.2

Amount = P+I

Principal = A-I

P = 291.2-11.2

P = 280.0

Hence patrick invested £280.0

Step-by-step explanation:

By setting up an inequality, the maximum number of vans that are needed to ferry 80 people are 7 vans.

To find the maximum number of vans needed to ferry 80 people using the given terms, let's set up an inequality. Let's use the variable "v" to represent the number of vans.

Since a van can ferry a maximum of 12 people, we can write the inequality as:

12v ≥ 80

Now, let's solve for "v":

Divide both sides of the inequality by 12.
v ≥ 80/12

Simplify the inequality.
v ≥ 6.67

Since we cannot have a fraction of a van, we need to round up to the nearest whole number:

v ≥ 7

Therefore, the maximum number of vans needed to ferry 80 people is 7 vans.

Answer:

(a) The linear depreciation function of the car which gives the worth of the car y after a number of years, t is given as follows;

y = 25,425 - 2,739 × t

(b) The value of the car 7 years from now is $6,252

(c) $2,739 per year

Step-by-step explanation:

The manufacture's suggested retail price (MSRP) for the car = $25,425

The amount the car is expected to be worth in 5 years = $11,730

(a) The linear depreciation is given as follows;

\(Depreciation \ Per \ Year \ = \dfrac{Cost \ of \, Asset - Salvage \ Value}{Life \ of \, Asset \ in \ use}\)

Where;

Cost of Asset = $25,425

Salvage Value = $11,730

Life of Asset in use = 5 years

We get;

\(Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year\)

Therefore, the linear depreciation function, can be written as follows;

y - 25,425 = -2,739×(t - 0)

y = -2,739·t + 0 + 25,425 = 25,425 -2,739·t

y = 25,425 - 2,739 × t

Where;

y = The expected worth of the car after a given number of years

t = The number of years used for the calculation of the depreciation

(b) The value of the car 7 years from now is given by substitution as follows;

Whet t = 7, we have;

y = 25,425 -2,739·t = y = 25,425 -2,739 × 7 = $6,252

The value of the car 7 years from now = $6,252

(c) \(Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year\)

The car is depreciating at a rate of $2,739 per year.
