Answer:

B. h(d) = 0.5d +12; 15 days

Step-by-step explanation:

here they want to write an equation to describe the growth of the plant.  set y = height of the plant (in cm).  set x = days (since planting).  the plant was planted on day 0 (x=0).  We know that the plant was 12 cm tall when it was first planted, so we know that y(0) = 12 cm.  y(0) just means the value of the equation y when x = 0, or y(x=0), or just y(0).  Every day the plant grows .5 cm so we know the value of y will increase at .5cm for every x days, or .5x.  Add the initial value of y (where x=0) and you have the equation y = 12 + .5x  (in cm).  usually we write equations in meters and not cm, so you can change it to y = .12 +.005x (in meters).  

now just set your equation equal to .185 meters and solve for x

.185 = .12 + .005x

.065 = .005x

x = 13 days

Answer

(a) Find out the  a rule to describe the function.

To prove

Let us assume that the days be represted by d .

Let us assume that the height of plant be represted by y.

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

Than the function becomes

y = 12 + 0.5 × d

y = 12 + 0.5d

(b) Find out after how many days will the zucchini plant be 0.195 meter tall .

To prove

Let us assume that the days be represted by d .

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

As

1meter = 100cm

0.195 meter convert into centimeter.

= 19.5cm

Than the equation becomes

12 + 0.5d = 19.5

0.5d = -12 + 19.5

0.5d = 7.5

d = 15 days

Therefore 15 days will the zucchini plant be 0.195 meter tall .

a) 12 + 0.5d               d=day

b) 0.195/0.5=0.39d

Answer:

15 days will the zucchini plant be 0.195 meter tall .

Step-by-step explanation:

y = 12 + 0.5d

(b) Find out after how many days will the zucchini plant be 0.195 meter tall .

To prove  

Let us assume that the days be represted by d .

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

As

1meter = 100cm

0.195 meter convert into centimeter.

= 19.5cm

Than the equation becomes

12 + 0.5d = 19.5

0.5d = -12 + 19.5  

0.5d = 7.5

d = \frac{7.5}{0.5}

d = 15 days  

Therefore 15 days will the zucchini plant be 0.195 meter tall .

To find the percentage of mugs that had two handles, you can use the following formula:

Percentage = (Number of mugs with two handles / Total number of mugs) * 100

In this case, the number of mugs with two handles is 16, and the total number of mugs is 6,400. Plugging these values into the formula:

Percentage = (16 / 6400) * 100

= 0.0025 * 100

= 0.25%

Therefore, 0.25% of the mugs in the box had two handles.

The z-score for a raw score of 12 in a distribution with a mean of 6 and a standard deviation of 3 is 2.

The z-score is a measure of how many standard deviations a raw score is above or below the mean of a distribution. It is calculated by subtracting the mean from the raw score and then dividing the result by the standard deviation.

In this case, we have a mean of 6 and a standard deviation of 3. To find the z-score for a raw score of 12, we can use the formula:

z = (x - μ) / σ

where x is the raw score, μ is the mean, and σ is the standard deviation.

Substituting the values we have, we get:

z = (12 - 6) / 3 = 2

Therefore, the z-score for a raw score of 12 in this distribution is 2. This means that the raw score of 12 is 2 standard deviations above the mean of 6. The z-score can be used to compare scores from different distributions, and to calculate probabilities and percentiles.

The data points are within the Control limits, indicating that the candy production process is operating consistently and without any significant issues that would require intervention or adjustment.

The process is in control or out of control, we can utilize control charts and statistical methods. In this case, we will use a control chart called the X-Bar chart, which is used to monitor the process mean over time.

1. Calculate the control limits:

  - First, we need to calculate the upper control limit (UCL) and lower control limit (LCL) for the X-Bar chart. The formula for the control limits is:

    UCL = mean + (3 * standard deviation)

    LCL = mean - (3 * standard deviation)

    Given:

    Mean = 16.8 grams

    Standard deviation = 0.7 grams

    UCL = 16.8 + (3 * 0.7) = 18.9 grams

    LCL = 16.8 - (3 * 0.7) = 14.7 grams

2. Plot the data points:

  - Plot the readings on the X-Bar chart using the given data points: 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.

3. Analyze the chart:

  - Examine the plotted data points to see if they fall within the control limits. If a data point falls outside the control limits, it suggests that the process may be out of control.

  In this case, we observe that all the data points fall within the control limits of 14.7 grams (LCL) and 18.9 grams (UCL). None of the points exceed these limits.

4. Conclusion:

  - Since all the data points fall within the control limits, we can conclude that the process is in control. There is no evidence of any special causes of variation present in the data.

the data points are within the control limits, indicating that the candy production process is operating consistently and without any significant issues that would require intervention or adjustment.

Because 6 cannot equal 2, this statement is false. As a result, this equation cannot be solved.

By fusing two expressions, the equation generates a mathematical expression, similar to an expression. A common equation would have been 3x - 5 = 16. The solution to this equation reveals that the variable x has a value of 7.

First, we employ the distributive property to simplify the left side of the equation:

3(x + 2) = 3x + 6

The right side of the calculation is then made simpler by grouping related terms together:

x+2x+2 = 3x+2

The initial equation is now:

3x + 6 = 3x + 2

3x both from sides are subtracted, giving us:

The population in the year 2020 is 4628

The given parameters are:

Initial, a = 12910

Rate, r = 5%

Since the population decreases, then we make use of an exponential decay function.

This is represented as:

f(n) = a * (1 - r)^n

So, we have:

f(n) = 12910 * (1 - 5%)^n

Evaluate the difference

f(n) = 12910 * 0.95^n

2020 is 20 years from 2000.

So, we have:

f(20) = 12910 * 0.95^20

Evaluate

f(20) = 4628

Hence, the population in the year 2020 is 4628

35 Degrees

Step-by-step explanation:

Given in figure.

Happy to help :)

The solution is, the value of the angle ADF = 35° .

Here, we have,

from the given diagram, we get,

ABCD is a trapezium.

EBC is a straight line.

F is the point on AB so that DFE is a straight line.

Angle BEF = 45°

Angle FBC = 100°

now, we have,

angle FBE = 180 - 100

                 = 80 degrees

now, from triangle BEF , we get,

Angle EFB = 55 degrees

again, as AFB is vertically opposite angle,

so, angle AFB = Angle EFB = 55 degrees

finally from triangle ADF , we get,

Angle ADF = 180 - 90 - 55

                  = 90 - 55

                  = 35 degrees

so, the value of the angle ADF = 35° .

Basically, in a function, you draw a vertical line. If that vertical line crosses the function more than once, then it is an invalid function.

Let me know if you need an example and I'll edit a picture in for you.

Answer:

A vertical line test is used to find out whether if a curve is a graph of a function or not.  If you are able to draw a vertical line, and it intersects more than one point on the curve, then it is not a function.

Step-by-step explanation:

Using imaginary unit i:

Recall i² = -1

-20 = -1 × 20 = i² × 20

If the line tangent to the polar curve at θ = π/3 is horizontal, it means that the derivative of the polar function with respect to θ evaluated at θ = π/3 is zero. Therefore, the condition that must be true is: f'(π/3) = 0.

The slope of a tangent line to a curve represents the rate of change of the curve at a given point. If the line tangent to the polar curve at θ = π/3 is horizontal, it means that the curve is not changing in the vertical direction at that point. In other words, the rate of change of the curve with respect to θ is zero at θ = π/3.

Mathematically, the derivative of the polar function r = f(θ) with respect to θ represents the rate of change of r with respect to θ. So, if the tangent line is horizontal at θ = π/3, it means that the derivative of f(θ) with respect to θ, which is f'(θ), evaluated at θ = π/3 is zero. Hence, the condition that must be true is f'(π/3) = 0.

The set of data we have is:

To represent the central tendency, we need a measure that is representative of most of the data we have. In the case that the values are similar or there is not much variation, it is most common to use the mean.

But in cases like the one, we have in this problem where most of the values are close together like 1, 2, or 3, and then we have a "much" greater or different value, like the 9 we have in the set, it is better to use the median.

The Median will be a better measure of the central tendency because it will reflect where most of the values of the set of data are located, and the 9 will not affect as much as it can affect by using the mean.

The probability that exactly 2 of the 3 marbles you select  red is 3/4.

There are 3 jars named A, B, and C and each jar has blue marbles and red marbles. A marble is randomly picked from each jar, with each marble equally likely to be chosen. To find: What is the probability that exactly 2 of the 3 marbles you select are red?

Solution: Total number of marbles in each jar = Total number of red marbles + Total number of blue marblesSince each marble is equally likely to be chosen, so the probability of choosing a red marble from any jar = the probability of choosing a blue marble from the same jar = (total number of red marbles) / (total number of marbles)

Let's find the total number of ways to choose one marble from each jar.There are 2 possible colors to pick from each jar. Therefore, by the multiplication rule of counting, there are 2 x 2 x 2 = 8 possible outcomes when we choose a marble from each jar.

The following table summarizes these possibilities:Jar A  Jar B  Jar C  Result  Number of outcomes  R,R B  B,R R  R,R,R  R,B,R  B,R,R  R,B,B  B,B,R  B,B,B  2  2  2  1  1  1  1  1  1  Total  8Now, let's find the probability that exactly 2 of the 3 marbles selected are red:

There are three ways to pick two red marbles and one blue marble, from jars A, B, and C, respectively: R,R,B; B,R,R; and R,B,R.The number of ways to pick R,R,B is: 2 x 2 x 2 = 8. So the probability of picking R,R,B is: P(R,R,B) = (2/4) x (2/4) x (2/4) = 1/4The number of ways to pick B,R,R is: 2 x 2 x 2 = 8.

So the probability of picking B,R,R is: P(B,R,R) = (2/4) x (2/4) x (2/4) = 1/4The number of ways to pick R,B,R is: 2 x 2 x 2 = 8. So the probability of picking R,B,R is: P(R,B,R) = (2/4) x (2/4) x (2/4) = 1/4So the total probability of picking exactly 2 red marbles is: P(exactly 2 red) = P(R,R,B) + P(B,R,R) + P(R,B,R) = 1/4 + 1/4 + 1/4 = 3/4

With each marble equally likely to be chosen, the probability of the exact 2 of the 3 marbles selected are red is 3/4.
