Answer:

You can use a function to solve this.

Since we are talking about percents, this will be an exponential function.

The general form of exponential function is  where a is the y intercept and b is the rate of change.

For this question, we have a percentage thingamajig here. The first thing we need to do is convert the percentage to a decimal. So if it is a 16% increase, we will convert that to 1.16. 1.16 will be the variable b

The video got 250 views on the first day. So that means the variable a will equal 250.

The final function will be:

To finally solve this, we need to replace f(x) with f(12) and the other x in the formula with 12 as well. This is because the question is asking for the number of views in 12 days.

So after solving the function, we get 1484.0067... but since we can't have a fraction of a view, we will round that down to 1484 views.Step-by-step explanation:

The total number of views after 5 days is 3836.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, on the first day it was posted online, a music video got 1850 views.

The number of views that the video got each day increased by 20% per day.

Sn = a(1 – r)ⁿ/(1 – r)

S₅= 1850(1+0.2)⁵/(1+0.2)

= (1850×1.2⁵)/1.2

= 4603.392/1.2

= 3836.16

≈ 3836

Therefore, the total number of views after 5 days is 3836.

Answer:

The interval estimate is:

41.5 - 2.45 ≤ true average time ≤ 41.5 + 2.45

or

38.05 ≤ true average time ≤ 44.95

Inequality notation:

[38.05, 44.95]

The interval estimate that will estimate the true average time that people spend brushing their teeth is [39.05, 43.95] seconds.

Given that the mean time spent brushing teeth from the sample is 41.5 seconds, and the margin of error is 2.45 seconds, we can construct a confidence interval estimate using the formula:

(sample mean) ± (margin of error)

Substituting the given values, we get:

41.5 ± 2.45

Simplifying, we get:

[39.05, 43.95]

Therefore, we can be 95% confident that the true average time that all people spend brushing their teeth falls within this interval.

Inga could use the first, third and the fourth equation for solving the given quadratic equation.

What is a quadratic equation?

A quadratic equation is any algebraic equation that may be written in standard form as where x denotes an unknown number and where a, b, and c denote known values, where a = 0.

1. 2 (\(x^{2}\) + 6x + 9) = 3 + 18

This can be simplified by using the multiplication and the addition operation on both the sides.

2. x + 3 = ± \(\sqrt{\frac{21}{2} }\)

This can be solved using the quadratic formula and obtaining the values for x.

3. 2 (\(x^{2}\) + 6x) = 3

This again can be simplified by using the multiplication and the addition operation on both the sides.

Hence, Inga could use the first, third and the fourth equation for solving the given quadratic equation.

Answer:

( 14 , 0 )

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 3*x+6*y-(42)= Pull out like factors :

  3x + 6y - 42  =   3 • (x + 2y - 14)

This equation has no solution.

A a non-zero constant never equals zero.

When he is halfway to the first base, the distance between the second base and the distance is decreasing at the rate of about 10.73 ft/s.

The length of the side of the base is 90 ft. Its speed is 24 ft/s.

Let x = distance he has run at time t and

D = distance from second base at time t, then speed dx/dt = 24 and we calculate dD/dt where x = 45.

From Pythagorean Theorem,

\(D^{2} =(90-x)^{2} +90^{2}\) ,

differentiating with respect to t

2D*dD/dt = 2 (90 − x) (−1) dx/dt + 0

D*dD/dt = − (90 − x)dx/dt

Now, when x = 45,

D =\(\sqrt{(90-45)^{2}+90^{2} }\)

\(=\sqrt{45^{2}+90^{2} }\)

by substituting D we get,

\(\sqrt{45^{2}+90^{2} }\)dD/dt = − (90 − 45) · 24

dD/dt = −45 · 24/\(\sqrt{45^{2}+90^{2} }\)

= −10.73 ft/s

Hence, when he is halfway to the first base, the distance between the second base and the distance is decreasing at the rate of about 10.73 ft/s.

Step-by-step explanation:

8(j-4)=2(4j-16)

Distribute

8j - 32 = 8j - 32

Subtract 8j from each side

8j-8j -32 = 8j-8j -32

-32 = -32

This is always true so there are infinite solutions

Answer:

All Real Numbers Are Solutions

Explanation:

8(j − 4) = 2(4j − 16)

[ Simplify both sides of the equation ]

8(j − 4) = 2(4j − 16)

(8)(j) + (8)(−4) = (2)(4j) + (2)(−16) (Distribute)

8j + −32 = 8j + −32

8j − 32 = 8j − 32

[ Subtract 8j from both sides ]

8j − 32 − 8j = 8j − 32 − 8j

−32 = −32

[ Add 32 to both sides ]

−32 + 32 = −32 + 32

0 = 0

Therefore, all real numbers are solutions.

A treatment is a particular combination of levels of the factors involved in a study.

In experimental design and research, a treatment refers to a specific combination of levels of the factors being studied. Factors are the variables or conditions that researchers manipulate or observe in order to analyze their effects on the outcome of interest. Each factor can have different levels or values, and a treatment represents a specific combination of these levels.

For example, consider a study examining the effects of fertilizer type (factor) on plant growth. The factor "fertilizer type" may have two levels: organic and synthetic. A treatment would then be a specific combination of these levels, such as "organic fertilizer" or "synthetic fertilizer." Researchers would assign different treatments to different groups or plots to compare their effects on plant growth.

By systematically varying the treatments, researchers can assess the impact of different factor levels on the outcome variable and draw conclusions about their relationships. The concept of treatments is essential for conducting experiments and allows researchers to understand the effects of specific combinations of factors in a controlled and structured manner.

the change in the area of the rectangle is given by the expression -6x - x^2 cm².

The original area of the rectangle is given by the product of its length and width, which is 14 cm * 10 cm = 140 cm². After modifying the rectangle into a square, the length and width will both be reduced by x cm. Thus, the new dimensions of the square will be (14 - x) cm by (10 + x) cm.

The area of the square is equal to the side length squared, so the new area can be expressed as (14 - x) cm * (10 + x) cm = (140 + 4x - 10x - x^2) cm² = (140 - 6x - x^2) cm².

To determine the change in area, we subtract the original area from the new area: (140 - 6x - x^2) cm² - 140 cm² = -6x - x^2 cm².

Therefore, the change in the area of the rectangle is given by the expression -6x - x^2 cm².

As a college basketball player makes 70% of his free throws, there is a 0.833 chance that he will convert at least two of them.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty. Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.

Here,

free throws made by a college basketball player=70%

=70/100

the probability that he makes at least two of the free throws,

=(70/100)²+(70/100)³

It took both Sandy and Tom 54 seconds to cover the same distance.

We can set up an equation based on their relative speed

Take the supposition that Tom needs "t" seconds to travel the distance. Sandy started jogging 12 seconds before Tom, so it will take her "t + 12" seconds longer to complete the same distance.

To determine the distance traveled by Sandy, multiply her speed (7 meters per second) by her time (t + 12) seconds. Tom's distance traveled may be determined by dividing his speed (9 meters per second) by his time (t) seconds.

Equating the distances covered by Sandy and Tom:

7(t + 12) = 9t

Expanding the equation:

7t + 84 = 9t

Subtracting 7t from both sides:

84 = 2t

Dividing both sides by 2:

t = 42

Tom traveled the distance in 42 seconds as a result. We add the 12-second lead Sandy had to determine the time it took for both Sandy and Tom to travel the same distance:

t + 12 = 42 + 12 = 54

So, it took both Sandy and Tom 54 seconds to cover the same distance.

However, it is worth noting that monitoring and conservation efforts play a crucial role in minimizing manatee deaths caused by power boats. In order to calculate the residual, we need both the observed and predicted values. However, in the given information, only the observed values are provided—581 thousand power boat registrations and 38 manatee deaths. Without a predicted value or expected number of manatee deaths, we cannot calculate the residual. The concept of a residual is commonly used in statistical modeling to assess the accuracy of a prediction or estimate. It represents the difference between the observed value and the predicted value based on a statistical model. In this case, without any prediction or expected value, we lack the necessary information to calculate the residual. Nonetheless, it is important to address the issue of manatee deaths caused by power boats. These deaths can have a significant impact on manatee populations and their conservation. Conservation efforts, such as speed limits, designated manatee protection zones, and public awareness campaigns, are implemented to reduce the risks to manatees from power boat collisions. Monitoring the number of manatee deaths and implementing measures to mitigate these risks are crucial steps in protecting these gentle creatures and ensuring their long-term survival.
