In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

Let 'x' and 'y' be the number of minutes spent on drawing and writing a comic book, respectively. Then the equations are given as,

x + y = 75          ....1

x = y + 25         ....2

From equations 1 and 2, then we have

y + 25 + y = 75

Probability that exactly one doesn't grow is 0.004

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

If a seed is planted, it has a 60% chance of growing into a healthy plant.

the probability of growing is 60/100 = 0.6

the probability of not growing is 1-0.6 = 0.4

eleven seeds are planted,

and 10 should grow and exactly one doesn't grow

so probability = 0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.4=0.004031

= 0.004

Answer:

Value of account after t years is
[tex]A = \boxed{190( 1.0178)^{4t}}[/tex]

Percentage of growth per year

CAGR = [tex]\boxed{7.31\%}[/tex]

Step-by-step explanation:

The generalized equation for the accrued value of an amount P(the principal) deposited at i% annual interest compounded n times a year for t years is

[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]

where r = i/100, the interest rate expressed as a decimal

Given P = $190
i = 7.1% ==> r = 7.1/100 = 0.071

Since the interest is compounded quarterly and there are 4 quarters in a year, the interest is compounded 4 times a year so n = 4

[tex]A = 190 \left(1 + \dfrac{0.071}{4}\right)^{4t}[/tex]

[tex]A = 190\left(1 + 0.01775\right)^{4t}}\\\\A = 190( 1.01775)^{4t}[/tex]\

Rounding the annual growth rate to 4 decimal places gives

[tex]A = P(1.0178)^{4t}[/tex]

In one year, the investment of $190 will grow to
[tex]A = 190(1.0178)^{4}[/tex]

[tex]A = $203.89[/tex]

Compound Annual Growth = = 203.89 - 190 = $13.89

Compound Annual Growth Rage(CAGR) = $13.89/$190 = 0.073105

As a percentage, CAGR Percent = 0.073105 x 100 = 7.3105% or rounded to nearest hundredth it would be 7.31%

a. Brand U will be $1,051.92 cheaper than Brand V. Option A is the correct answer to the given question.

To calculate the lifetime cost of each oven, we need to consider the initial purchase price, daily electricity costs, and lifespan. For Brand U, the lifetime cost would be:

Lifetime cost = Price + (Avg. Cost/Day × 365 days × Lifespan)

= $2,250 + ($0.16 × 365 × 24)

= $4,013.60.

For Brand V, assuming two repurchases to equalize the lifespan, the lifetime cost would be: Lifetime cost = Price + (Avg. Cost/Day × 365 days × Lifespan × 3)

= $725 × 3 + ($0.28 × 365 × 8 × 3)

= $3,961.68.

Therefore, Brand U will have a lower lifetime cost than Brand V by $1,051.92 (option a).

The full meaning of CCTV is Closed-Circuit Television. It refers to a system of video cameras and monitors that are used for surveillance and security purposes. The cameras capture live video footage, which is then transmitted to a set of monitors or a central control room for viewing. The cameras are connected to the monitors through a closed circuit, meaning that the signal is not broadcast publicly and can only be viewed by authorized individuals. CCTV systems are commonly used in homes, businesses, and public spaces to deter crime and provide a record of events.

The correlation between your daily calorie intake and your GPA is not likely to be immediately apparent, and it would require further investigation to determine whether there is a positive or negative correlation, or no linear relationship between the two variables.

It is difficult to predict the correlation between your daily calorie intake and your GPA as they are not obviously related variables. However, it is possible that there may be a weak or indirect relationship between the two variables.

          If a person is consuming a well-balanced diet with the right amount of nutrients, vitamins, and minerals, they may have the energy and focus necessary to perform well academically. In this case, there may be a positive correlation between calorie intake and GPA. Alternatively, if a person is consuming an excessive amount of calories from unhealthy foods, they may be more likely to experience health problems that could impact their academic performance. In this case, there may be a negative correlation between calorie intake and GPA.

      On the other hand, there may be no direct linear relationship between the two variables, and other factors such as sleep, stress, exercise, and overall health may have a greater impact on academic performance than daily calorie intake.

The probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778.

To calculate the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice, we need to find the number of ways the dice can be rolled to get a sum less than or equal to 6 and divide it by the total number of possible outcomes.

There are 6 x 6 = 36 possible outcomes when rolling a pair of dice, since there are 6 possible outcomes for each die. To get a sum less than or equal to 6, the only possible outcomes are:

1+1 = 2

1+2 = 3

1+3 = 4

1+4 = 5

2+1 = 3

2+2 = 4

2+3 = 5

3+1 = 4

3+2 = 5

4+1 = 5

There are 10 possible outcomes that result in a sum less than or equal to 6. Therefore, the probability of rolling a sum less than or equal to 6 is:

P(sum less than or equal to 6) = number of favorable outcomes / total number of possible outcomes

P(sum less than or equal to 6) = 10 / 36

Simplifying this fraction, we get:

P(sum less than or equal to 6) = 5 / 18

Therefore, the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778 when rounded to four decimal places.

Mean = E(x) = 25 , and variance = var(x) = 16 multiply by the value by 3 and add 4

mean = 3 x 24 + 4 = 79

Variance = 3^2 x 16 = 9 x 16 = 144

=> mean = 79 , variance = 144

Variance is a statistical measure that represents the degree of dispersion or variation in a set of data. It is the average of the squared differences between each value and the mean of the data set. The variance shows how spread out the data is and how much each value deviates from the average.

A high variance indicates that the data points are spread out over a wide range, while a low variance indicates that the data points are clustered around the mean. Variance is useful in various fields, including finance, engineering, and social sciences, where it is used to analyze data, test hypotheses, and develop predictive models. Standard deviation is a more intuitive measure of variation as it is expressed in the same units as the data, while variance is expressed in squared units.

There are many ways that baseball players and basketball players can be selected from a group of athletes who play both sports.

One way is to use a selection process that allows for both players to be chosen based on their individual merits. For example, a team could use a combination of criteria such as previous performance, physical fitness, athleticism, and skill level to select the most suitable players for each sport. This could be done by assigning each player a score based on these criteria and then selecting the highest scoring players for each position.Another way to select players from a group of athletes playing both sports is to use a draft system. This system would allow teams to choose players based on the team's needs, rather than individual merits. This could be done by assigning each player an overall ranking and then allowing teams to select players in order of their ranking. A third way to select players from a group of athletes playing both sports is to have a tryout or combine where players can showcase their skills and abilities. This allows teams to evaluate players in a more comprehensive way and make sure they are selecting the best players for their team. Finally, teams can also use a combination of the above methods to select players. For example, they could use a combination of a draft system, individual merit selection, and a tryout/combine to get a better idea of which players are the best fit for their team.
