Answer: D 36л

Step-by-step explanation:

s = θr

where r is the radius of the circle.  given that the arc length is 6, and the central angle is π/3 radians r:

6 = (π/3)r

r = 6/(π/3) = 18/π

the circumference of the circle is given by:

C = 2πr

Substituting r = 18/π, we get:C = 2π(18/π) = 36

Answer:

According to the model. the weight of the candle after S hours of burning would be about 15.05 ounces

Step-by-step explanation:

If the burn rate is believed to be constant, determine the average burn rate for the eight candles as the ratio of weight loss per hour.

ounces lost over three hours

0.5+0.6+0.5÷0.7÷0.7÷0.5÷0.5÷0.6

8

* 0.575

0.575

ounces lost per hour on average

= 0.19

For 0 hours, the weight of each candle is 16 ounces. Therefore, w 16 - 0.19h.

This model can be used to predict the weight of the candle when h, the number of hours of burning, is 5.

W * 16 - 0.19(5)

W = 16 - 0.95

W = 15.05

According to the model. the weight of the candle after S hours of burning would be about 15.05 ounces.

The weighted mean of the deliveries each week can be found to be 5. 38 .

The weighted mean is a type of mean that takes into account, the weight of the various items in question.

First, find the total frequency :

= 1 + 5 + 4 + 3

= 13

The weighted mean would then be:

= ∑ ( weight of delivery x number of deliveries )

= ( 1 / 13 x 2 ) + ( 5 / 13 x 4 ) + ( 4 / 13 x 6 ) + ( 3 / 13 x 8 )

= 0. 15  + 1. 54 + 1. 84 + 1. 85

The answer of the given question based on the experimental probability is the next pizza sold at Downtown Pizza will have pepperoni is 2/3 or approximately 0.67.

Experimental probability is  ratio of number of times  event occurs to the total number of trials or observations conducted in  experiment or real-life situation. It is based on actual observations or data and is also known as empirical probability.

Experimental probability is used when it is not possible or feasible to determine the theoretical probability of an event, or when the theoretical probability does not match the actual outcomes observed in a given situation. In such cases, experimental probability provides an estimate of the likelihood of an event occurring based on real-life data.

The experimental probability that the next pizza sold will have pepperoni is the ratio of the number of pepperoni pizzas sold to the total number of pizzas sold in the recent past.

According to the problem, 4 of the last 6 pizzas sold had pepperoni. So, the experimental probability of the next pizza sold having pepperoni is:

experimental probability = number of pepperoni pizzas sold / total number of pizzas sold

experimental probability = 4 / 6

experimental probability = 2 / 3

Therefore, the experimental probability that the next pizza sold at Downtown Pizza will have pepperoni is 2/3 or approximately 0.67.

All the correct values are,

⇒ ∠ABD = 60°

⇒ ∠ADB = 90°

⇒ ∠BAD = 30°

⇒ ∠CAD = 30°

⇒ BD = 3

⇒ AD = √27

⇒ The value of area of triangle ABC is, 3√27

Given that;

In the diagram shown, ABC is equilateral. AD is an altitude.

Hence, We get;

All the angles of a equilateral triangle are,

⇒ 60°

Thus, We get;

⇒ ∠ABD = 60°

Since, AD is an altitude.

⇒ ∠ADB = 90°

And,

⇒ ∠BAD = 60 / 2 = 30°

⇒ ∠CAD = 60/2 = 30°

By Pythagoras theorem;

AB² = AD² + BD²

6² = AD² + 3²

36 = AD² + 9

AD² = 27

AD = √27

There are four possible outcomes in this game: winning $1, winning $5, winning $10, or winning $0.

The probability of winning $1is the probability of drawing one of the 11 hearts that are not the ace of hearts. There are 52 cards in the deck, so the probability of drawing any one of them is 1/52. However, there are 11 hearts that win $1, so the probability of winning $1 is:

P(W = $1 ) = 11/52

The probability of winning $5 is the probability of drawing the ace of hearts, which is 1/52.

P(W = $5) = 1/52

The probability of winning $10 is the probability of drawing the king of spades, which is also 1/52.

P(W = $10) = 1/52

The probability of winning $0 is the probability of drawing any other card, which is 39/52.

Answer:

To determine the scale factor used, we need to find the ratio of corresponding side lengths in both triangles.

Let's compare the length of the first side in both triangles:

x/3.8 = 2/4.8

Cross-multiplying, we get:

4.8x = 7.6

Dividing both sides by 4.8, we get:

x = 1.58

Now, let's compare the length of the second side in both triangles:

2.4/4.2 = 0.57

Finally, let's compare the length of the third side in both triangles:

2.1/4.8 = 0.44

Since the scale factor is the same for all corresponding side lengths, we can take the average of the ratios:

(scale factor) = (1.58/3.8 + 0.57 + 0.44)/3

(scale factor) = 1.01

Therefore, the scale factor used is approximately 1.

b. The interpretation of the pie chart produced in Question 8a) depends on the shape and distribution of the chart. Two probable justifications for the behavior of the data are:

Dominance of certain NOCs: The pie chart may show that certain NOCs have a significantly higher share of medal winnings compared to others. This may be due to the dominance of these NOCs in specific sports or events, or due to their superior training and preparation.

Answer: ∠EFB, ∠DFE, and ∠CFB

Step-by-step explanation:

Starting Angle: ∠CFD

Since its in an X formation: ∠EFB, ∠DFE, and ∠CFB would all work.

It should be noted that to find the equation of a line, two pieces of information are necessary: the slope and coordinates of a point on the line.

Also, to acquire this, one can leverage either the point-slope form or the slope-intercept form to compose it.

If both the slope (m) and coordinates of the point  (x1, y1) on the line are known, then one can express the equation in its point-slope style as follows:

y - y1 = m(x - x1)

Or, if only the slope (m) and the y-intercept (b), which is the value of y where the line crosses the y-axis, are accessible, then the equation can be expressed via the slope-intercept form with: y = mx + b

The monthly payments will thus be $1,612.81.

The annual effective rate on this loan is 5.78%.

We can use the following loan payment formula to determine the loan payment:

Loan Payment  = [tex]\\\frac{p * \frac{r}{n} }{1 - (1 + \frac{r}{n} )^{-n *t} }[/tex]

where P = borrowed amount = $69,300

r = yearly interest rate (decimal) = 0.056

n = number of times compounded per year = 12

t = number of years = 4

When we plug in the values, we get:

Loan Payment = [69300 x (0.056/12)] / [1 - (1 + 0.056/12)^(-12*4)]

= $1,612.81 (to the nearest cent)

The monthly payments will thus be $1,612.81.

We can use the following calculation to obtain the effective annual rate:

Annual Effective Rate =[tex](1 + r/n)^{n-1}[/tex]

When we plug in the values, we get:

Annual Effective Rate =[tex](1 + 0.056/12)^{12 - 1}[/tex]= 0.0578 or 5.78%
