A linear function consists of functions where the variables has exponents of 1.

The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

y = output variable

m = slope

x = input variable

c = y intercept

The two graphs shown the first from the left represents a positive slope while the second is a negative slope

Cole and Erika are both positive slopes while Landry has a negative slope. This makes Landry to be sure of the second graph

Considering c (y intercept)

In Cole's equation c = -1 and in Erika's equation c = +4

Erika's equation coincides with the graph with positive slope and Landry matches with second graph.

To answer this query, we employ the conditional probability formula. It is, where

P(B|A) is the likelihood that event B will occur in the absence of event A.

is the likelihood that both A and B will occur.

P(A) denotes the likelihood that A will occur.

The following probability applies:

50% chance of winning a prize with the fair coin.

There is a 100-78 = 22% chance of winning a reward with the biased coin.

50% chance of selecting each coin.

What is the likelihood that you would choose the biased coin if you were to win a prize?

Event A: Receiving the award

Choosing the skewed coin is event B.

the likelihood of selecting the skewed coin and obtaining the reward.

p(A∩B) = 0.5 * 0.22 = 0.11

probability of winning the prize:

p(A) = 0.5*0.22 + 0.5 *0.5 = 0.36

If the tank begins with 103 gallons, then 93 gallon will remain after 2 seconds

The quantity of fuel releases from the container = 5 gallon per second

Consider the fuel remaining in the container = y

Consider the number of seconds that have passed since the fuel started dispensing = x

Then x and y satisfy a linear relationship

The quantity of fuel in the tank at the beginning = 103 gallon

Time taken = 2 seconds

Then the equation will be

y = 103 - 5x

Time taken is x = 2

y = 103 - 5× 2

y = 103 - 10

y = 93 gallon

Hence, if the tank begins with 103 gallons, then 93 gallon will remain after 2 seconds

The estimate, a predicted time of 81.54 minutes, is both reliable and reasonable. the correct option is (A).

Given that,

The projected amount of time spent with family for someone who spent 36 minutes playing video games is 81.54 minutes, according to the line of best fit.

To find :

Is it appropriate to make the aforementioned forecast using this line of best fit

According to the  "line of best fit" it is that along which the sum of squares of deviation is minimum. This means the line of best fit minimizes the deviation or we can say error due to which it gives better estimate than other method.so, the predicted number of minutes spent with family is both reliable and reasonable.

The value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1 ​.

According to the question,

We have the following equation:

f-2g+3=2f-39+2=1 ​

Now, we will equate both these equations to 1:

f-2g+3 = 1

Subtracting 3 from both sides:

f-2g = 1-3

f-2g = -2 ..(1)

2f-39+2 = 1

2f -37 = 1

Adding 37 to both sides:

2f = 1+37

2f = 38

Dividing by 2 on both sides:

f = 38/2

f = 19

Putting this value of f in equation 1:

f-2g = -2

19-2g = -2

-2g = -2-19

-2g = -21

g = 21/2

g = 10.5

Hence, the value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1​.

What are the exponential functions?

A mathematical function called an exponential function is employed frequently in everyday life. It is primarily used to compute investments, model populations, find exponential decay or exponential growth, and so forth. You will discover the formulas, guidelines, characteristics, graphs, derivatives, exponential series, and examples of exponential functions in this article. The formula for an exponential function is f (x) = axe, where x is a variable and an is a constant that serves as the function's base and must be greater than 0. The transcendental number e, or roughly 2.71828, is the most frequently used exponential function base.

With the highest power in exponential function,

Step-by-step explanation:

Points given:

This is a horizontal line with constant y - value of - 3.

So it equation is y = - 3.

For the given function 4xy-4x+4y³ = -36 , value of dy/dt for the condition dx/dt = -16 , x= 4, y= -1 is equal to dy/dt = -32/7.

As given in the question,

Given function is equal to :

4xy-4x+4y³ = -36

Let us consider x and y are function of t.

Now , evaluate the derivative of function with respect to t we get,

4x(dy/dt) + 4y(dx/dt) -4(dx/dt) + 12y²(dy/dt) = 0

⇒( 4x + 12y² ) (dy/dt) + ( 4y -4 ) (dx/dt) = 0

Substitute the value of dx/dt = -16, x = 4 , y = -1 we get,

[ 4(4) + 12(-1)² ](dy/dt) + [ 4(-1) - 4 ] (-16) =0

⇒(16 +12) (dy/dt) + (-8)(-16) = 0

⇒ dy/dt = - ( 8× 16)/ 28

⇒ dy/dt = -32/7

Therefore, for the given function 4xy-4x+4y³ = -36 , value of dy/dt for the condition dx/dt = -16 , x= 4, y= -1 is equal to dy/dt = -32/7.

The complete question is:

Assume x and y are functions of t. Evaluate dy/dt , for 4xy-4x+4y³ = -36, with the conditions dx/dt = -16 , x = 4 , y = -1.

Standard deviation - The value of x is 1.96.

What is standard normal distribution?

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.

As given, for a standard normal distribution, 95% of the data points are contained in the interval [ -x , x ].

The standard normal distribution, commonly known as the z-distribution, is a unique type of normal distribution in which the mean and standard deviation are both equal to 1. By transforming its values into z-scores, any normal distribution can be standardised. Z-scores indicate how far away from the mean each number is from.
