Describe some common or unique mathematical formulas that you use in your life.

Answer:

C

Step-by-step explanation:

Since there are two arcs and they both make up a circle, and a circle has 360 degrees.

NPL+NL=360

The measure of NPL is twice the measure of NL so

it now

2NL=NPL

Substitute that in the equation

2NL+NL=360

3NL=360

NL=120

Since NL subtends NML they are equal so NML=120

The maximum possible revenue from this concert is less than $20,000

The correct answer is an option (a)

In this question, we have been given a maximum of 1000 people- With ticket prices at $30_ the concert venue holds average attendance is 650 people: It is predicted that for each dollar the ticket price is lowered, approximately 25 more people attend.

We need to find the maximum possible revenue from this concert.

Revenue = (attendance/number of tickets sold)(price per ticket)

Let y = attendance/number of tickets sold

and x = price per ticket.

Let m = -25 and a point in our function be (30, 650).

From this information, a function in point-slope form would be:

y - 650 = -25(x - 30)

y = -25x + 750 + 650

y = -25x + 1400

so, the revenue function would be,

R(x) = yx

R(x) = -25x² + 1400x

The maximum of  the revenue function is at the vertex.

-b/2a = -1400/(-2 * 25)

         = 28

so, the maximum revenue from this concert:

R(28) = -25(28)² + 1400(28)

         = 19600

Therefore, the revenue from this concert is Less than $20,000

If the value stated by a null hypothesis is within the confidence interval, then the decision would have likely been to retain the null hypothesis.

In hypothesis testing, the null hypothesis represents the default assumption or the claim that there is no significant difference or relationship between variables. The confidence interval, on the other hand, provides a range of plausible values for the population parameter based on sample data. If the value stated by the null hypothesis falls within the confidence interval, it means that the null hypothesis value is considered plausible or consistent with the observed data.

In this case, there is insufficient evidence to reject the null hypothesis, and the decision would be to retain it. On the other hand, if the null hypothesis value is outside the confidence interval, it suggests that the null hypothesis is unlikely, and the decision would be to reject it in favor of an alternative hypothesis.

The perimeter of the figure 1 is 36 centimeter.

From the given figure,

1) Missing side = 8-5 = 3 cm

Here, perimeter = 8+10+5+7+3+3 = 36 cm

2) Missing side = 12-8 = 4 cm

Missing side = 9-7 = 2 cm

Here, perimeter = 12+7+4+8+9+2

= 42 cm

3) Missing side = 60-40 = 20 mm

Missing side = 30+15 = 45 mm

Perimeter = 60+15+40+30+20+45

= 210 mm

4) Missing side = 71/2 + 11/2

= 9 m

Missing side = 4+2 = 6m

Perimeter = \(7\frac{1}{2}\) + 4+ \(1\frac{1}{2}\) +2+9+6

= 9+4+2+9+6

= 30 m

Therefore, the perimeter of the figure 1 is 36 centimeter.

Answer:

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6

Step-by-step explanation:

Let the two consecutive even integers be x and x+2

Here x is the smaller even integer and x+2 is the next so it will be larger.

Now according to the given statement

Sum of both: \(x+x+2\)

difference of 3 times the larger & 2 times the smaller:\(3(x+2)-2x\)

Putting the sum and difference equal:

\(x+x+2 = 3(x+2)-2x\)

Solving the equation

\(2x+2 = 3x+6-2x\\2x+2 = x+6\\2x+2-x = x+6-x\\x+2 = 6\\x+2-2 = 6-2\\x = 4\)

The next integer will be:

\(x+2 = 4+2 = 6\)

Hence,

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6.

The centroid in the x-direction of the shaded area can be found by calculating the weighted average of the x-coordinates of the area. Here is the step-by-step explanation:

To find the centroid in the x-direction of the shaded area, we calculate the weighted average of the x-coordinates of the centroids of the circular segment and rectangle. The x-coordinate of the centroid of the circular segment is determined by the midpoint of the chord, while the x-coordinate of the centroid of the rectangle is given. By applying the formula for the weighted average, we can determine the centroid in the x-direction.

One bottle of liquid plant food is enough for at least 12 weeks, and potentially a bit more.

William uses 40 milliliters of liquid plant food per week, so to find out how much plant food he needs for 12 weeks, we can simply multiply the weekly usage by the number of weeks:

Amount of plant food needed for 12 weeks = 40 milliliters/week x 12 weeks = 480 milliliters

So, William needs 480 milliliters of liquid plant food for 12 weeks.

Since the bottle of liquid plant food, William purchased contains 0.5 liters or 500 milliliters of liquid plant food, we can see that one bottle is enough for 12 weeks since 480 milliliters is less than the total amount of liquid plant food in the bottle.

In fact, we can calculate how many weeks one bottle of liquid plant food will last William by dividing the total amount of liquid plant food in the bottle by the amount used per week:

Time to use up the liquid plant food = (Total amount of liquid plant food) / (Amount used per week) = 500 ml / 40 ml/week ≈ 12.5 weeks

So, we can say that one bottle of liquid plant food is enough for at least 12 weeks, and potentially a bit more.

Answer:

Step-by-step explanation:

Answer:

\(m>2.40\)

Step-by-step explanation:

Let m denotes the number of minutes of phone use in a month.

In plan a there is no monthly fee, but the customer pays 8 cents per minute of use.

Total cost of plan a = \(8m\)

In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use.

Total cost of plan b = \(2.40+7m\)

To find amount of monthly phone use for which plan a cost more than plan b, solve the inequality \(8m>2.40+7m\).

\(8m>2.40+7m\\8m-7m>2.40\\m>2.40\)

This indicates that approximately 47.7% of the sampled subjects responded definitely or probably not beneficial to family planning.

From the given data, we can analyze the proportions of respondents who considered family planning beneficial and those who did not.

The proportion of respondents who responded definitely or probably beneficial is 651 out of 1245 sampled subjects. Therefore, the proportion can be calculated as:

Proportion = 651/1245 ≈ 0.523

This indicates that approximately 52.3% of the sampled subjects responded definitely or probably beneficial to family planning.

On the other hand, the proportion of respondents who responded definitely or probably not beneficial is 594 out of 1245 sampled subjects. The proportion can be calculated as:

Proportion = 594/1245 ≈ 0.477

This means that roughly 47.7% of the sampled participants indicated that family planning was either definitely advantageous or probably not beneficial.
