T is not a function of G as they don't have a constant of proportionality.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.

It should be noted that the constant of proportionality simply means the ratio that relates two given values in what is known as a proportional relationship. In this case, other names for the constant of proportionality are the constant ratio, constant rate, unit rate, constant of variation, or the rate of change

Since the parking garage charges $5 for the first hour, $10 for up to two hours, and $12 for the entire day. This implies that they don't have a constant of proportionality.

In this case, the time doesn't have an effect on amount paid.

Probability to get at most 2 heads after flipping coin for 5 times is 1/2.

Probability is the ratio of good outcomes to all possible outcomes of an event is known as the probability.

The number of positive results for an experiment with n outcomes can be represented by the symbol x.

The probability of an event can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

With a fair coin, there are [tex]2^{5}[/tex] = 32 possible combinations of heads and tails after 5 flips.With 0 heads,5C0 = 5!/0!5! = 1 ways

get one head 5C1 = 5!/ 4!1! = 5 ways

To obtain precisely 2 heads,5C2 = 5!/ 2!3! = 10 ways

Obtain 3 heads,5C3 = 5!/ 3!2! = 10 ways

Total methods to gain at most 2 heads are 1+5+10 = 16.

Probability to get at most 2 heads is = ( total methods to gain at most 2 heads)/(total ways)

P(total methods to gain at most 2 heads) = 16/32 =1/2.

the answer is 14

simply multiply mika age by 2

since the difference is 7

meaning that mika is seven

and twice is 14

Answer:

Step-by-step explanation:

a. The equation for the cost of AT&T would be $100 + $15n, where n is the number of phones on the account. The equation for the cost of Sprint would be $200.

We can graph these equations on a coordinate plane with the x-axis representing the number of phones on the account and the y-axis representing the monthly cost. The graph for the cost of AT&T would be a straight line starting at the point (0,100) and going through the point (1,115), (2,130), etc. The graph for the cost of Sprint would be a horizontal line at the y-coordinate of 200.

b. In order to determine which company would be cheaper for Carly's family, we can simply plug in the number of phones they have (5) into each of the equations we derived in part a. This would give us a cost of $200 for AT&T and $200 for Sprint. In this case, both companies would be equally cheap for Carly's family.

Alternatively, we could graph the equations and see which company's line is lower on the y-axis for the given number of phones (5). This would also show that both companies would be equally cheap for Carly's family in this case.

Answer:

Solve for x

Inequality Form: x>10.4

Interval Notation: (10.4,∞)

Step-by-step explanation:

Willka covers 4.5 m² in 1L paint and 45 m² in 10L in paint according to the table.

What are equivalent ratios?

We know that the equivalent ratio is defined as the ratio which is having the same proportion as given ratio.

Now, using the division property of the ratio, we will divide the given ratio with the same number both sides.

According to the given question:

If Willka covers 13.5 m² with 3L paint, to cover x m² she will need 1L paint

By equivalent ratios

13.5 : 3 = x : 1

x = 13.5 / 3

x = 4.5

Similarly to cover y m² she needs 10L paint

13.5 : 3 = y : 10

y = 13.5 x 10/3

y = 45

Therefore the answer for the blanks is 4.5 and 45.

From the data , the miles per gallon is  

199.2 mi  / 6 gal       or      265.6 mi / 8 gal      or     863.2 / 26    

   = 33.2 mi/gal

for 50 gallons this would be

    33.2 mi / gal   *  50 gal = 1660 mi

The standard form is y= 1/2x+ 4.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

(2,5) and (-4,2)

So, slope

= (2- 5)/ ( -4 - 2)

= -3 / (-6)

= 1/2

and, using slope- intercept form

y- 5 = 1/2( x - 2)

y-5 = 1/2x -1

y= 1/2x + 4

Hence, the standard form is y= 1/2x+ 4.

A relation is a specific instance of a function graph. A function is truly equivalent to its graph in set theory and the current mathematical underpinnings.

It is frequently more helpful to think about functions as mappings, which include the sets that constitute the domain and the codomain in addition to the relationship between input and output. For instance, the codomain should be considered while determining if a function is onto (surjective) or not. The codomain of a function is not determined by the graph alone.

It is typical to use the phrases function and graph of a function interchangeably since, although referring to the same thing, they suggest distinct ways of looking at it.

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

We are given two plots of normal distributions A and B.

The mean of a normal distribution is located at the center of the plot.

Since the centers of both of the normal distributions A and B seems to be aligned, therefore, they both seems to have equal means.

The standard deviation basically determines the shape of the distribution.

As you can see, the normal distribution A is more spread out and thus has a larger standard deviation than normal distribution B.
