Final answer:

The probability of a randomly chosen dental appointment being with a patient over 60 years old or for a broken tooth is 0.52, given that the events are independent.

Explanation:

The probability that a randomly chosen appointment is with patients over 60 years old or is for a broken tooth, given that these are independent events, can be found by using the formula for the probability of the union of two independent events: P(A ∪ B) = P(A) + P(B) - P(A ∩ B). Since the events are independent, P(A ∩ B) is equal to P(A) × P(B).

In this case, P(patients over 60) = 0.2, and P(broken tooth) = 0.4. Since they are independent events, the probability of both occurring together is 0.2 × 0.4 = 0.08. Thus, the combined probability is 0.2 + 0.4 - 0.08 = 0.52.

The probability that an appointment is with a patient over 60 years old or for a broken tooth is 0.52, or 52%.

Answer: 288π in³

Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is [tex]v =\frac{4}{3} \pi r^{3}[/tex].

Here, we are given that our sphere has a radius of 6 inches.

So plugging into the formula, we have [tex](\frac{4}{3})(\pi)(6 in.)^{3}[/tex].

Start by simplifying the exponent.

(6 in.)³ is equal to 6 inches · 6 inches · 6 inches or 216 in³.

So we have [tex](\frac{4}{3})(216 in^{3})(\pi)[/tex].

Notice that we can cross cancel 3 and 216 to 1 and 72.

So we have (4)(72in³)(π)  which is equal to 288π in³.

So the volume of the sphere is 288π in³.

I had this question.

Answer:

Step-by-step explanation:

Given that the markup percent is based on the cost of the product.

The cost of Burberry men's watch = $490

Markup percent = 40 %

= 40 % (490) = $196

The new selling price of the product = 196 + 490 = $686

The markup percent  of the selling price , (x%)686 = 196

x = 28.5 %

The markup is 28.5 % of the selling price

Final answer:

To calculate the dollar markup on a $490 item with a 40% markup, multiply the cost by 0.40 to get $196. The selling price is then the original cost plus the markup, totaling $686.

Explanation:

To find the dollar markup of a Burberry men's watch that costs $490 with a markup percent of 40%, you first need to convert the percentage to its decimal form by dividing by 100. This gives us 0.40. Next, you multiply the cost by the decimal form of the markup percentage to find the dollar markup.

Calculation:

$490 × 0.40 = $196

To find the selling price, add the dollar markup to the original cost.

Calculation:

$490 + $196 = $686

The dollar markup is $196, and the selling price for the Burberry men's watch is $686, both rounded to the nearest cent.

[tex] |6m - 54| \: > \: 0[/tex]

Step-by-step explanation:

Let

[tex]y = |6m - 54| [/tex]

We can factor 6 to get:

[tex]y = 6 |m - 9| [/tex]

This is the graph an absolute value function that opens upwards.

The vertex is at (0,9)

The range is

[tex]y \geqslant 0[/tex]

For m<9, the graph is always above the x-axis.

Therefore for m<9,

[tex] |6m - 54| \: > \: 0[/tex]

Answer:

|6m-54| ≥ 0

Step-by-step explanation:

Given: m<9 = m is less than 9

Solution:

|6m-54| > 0 is partially right, instead of just a regular sign of >. It should be ≥. Simply the answer is |6m-54| ≥ 0.

The value of the z-score is 1.33.

The z-score is defined as the mean (average) values, measured in terms of standard deviations from the mean.

The formula is used to calculate z-score is;

Z-score = (X-μ)/σ

We have, mean = 7 and σ =3.522 and X is  11.7.

Substitute all the values in the formula;

Z-score = (X-μ)/σ

= (11.7-7)/3.52

= 4.7/3.52

= 1.33

Hence, the value of the z-score is 1.33.

Answer:

the slope of the asymptotes are: 2 and -2

Step-by-step explanation:

As we know the hyperbola equation is:

[tex]\frac{(x-h)^2}{b^2}-\frac{(y-k)^2}{a^2}=1[/tex]

Given the hyperbola equation:

[tex]\frac{(x-1)^{2} }{4} - \frac{(y+2)^{2} }{16} = 1[/tex]

We have  a=2 and b=4, h=1 and k=-2

and the asymptote equation of a translate hyperbola with equation is:

[tex]y=\pm\frac{b}{a}(x-h)+k[/tex]

We substitute this values to get:

[tex]y=\pm\frac{4}{2}(x-1) -2[/tex]

https://brainly.com/question/16047910

Step-by-step explanation:

Simple

First we have to find out cost of each cake so

Cost of 1 cake = 13.20 ÷ 8 = 1.65

Cost of 12 cakes = 1.65 × 12 = 19.8

Each cake costs £1.65, so the total cost for 12 cakes would be £19.80. So, the cost of 12 cakes would be £19.80.

This question requires understanding of ratio and proportion. First, let's find the cost of 1 cake by dividing the total cost (£13.20) by the total number of cakes (8). Here, we get: £13.20 ÷ 8 = £1.65. This means that each cake costs £1.65. After finding the cost of a single cake, we can calculate the cost of 12 cakes by multiplying the cost of one cake (£1.65) by 12. This gives £1.65 × 12 = £19.80. So, the cost of 12 cakes would be £19.80.

Final answer:

The simplest form of the ratio of apple juice to coconut milk to orange juice given the amounts of 5 ml, 50 ml, and 15 ml respectively is 1:10:3.

Explanation:

To find the simplest form of the ratio of apple juice to coconut milk to orange juice, we will use the quantities provided: 5 ml of apple juice, 50 ml of coconut milk, and 15 ml of orange juice.

First, let's list the quantities in the order requested:

Apple juice: 5 ml

Coconut milk: 50 ml

Orange juice: 15 ml

Next, we will find the greatest common divisor (GCD) that these amounts have in common to simplify the ratio. The GCD for 5, 50, and 15 is 5.

Now, divide each quantity by the GCD:

5 ml apple juice ÷ 5 = 1

50 ml coconut milk ÷ 5 = 10

15 ml orange juice ÷ 5 = 3

So the ratio of apple juice to coconut milk to orange juice in its simplest form is:

1:10:3.

Final answer:

To find the simplest form of the ratio of apple juice to coconut milk to orange juice, divide the volume of each by the greatest common divisor. The result is a simplified ratio of 1:10:3 for apple juice, coconut milk, and orange juice, respectively.

Explanation:

In the given fruit cocktail recipe, we have the following measurements for each of the components: 15 ml of orange juice, 5 ml of apple juice, and 50 ml of coconut milk. To find the ratio of apple juice to coconut milk to orange juice in its simplest form, we will compare the volumes of each ingredient.

First, we will list the volumes of ingredients as a ratio:

Apple Juice : Coconut Milk : Orange Juice

5 ml : 50 ml : 15 ml

To simplify this ratio, we can divide each part by the greatest common divisor of the three numbers, which in this case is 5 ml. So, we get:

(5/5) ml : (50/5) ml : (15/5) ml

1 : 10 : 3

Therefore, the simplest form of the ratio is 1:10:3.

The answer to the missing measure based on the emoji values would be 365

How to find the value ?

To solve this set of emoji-based equations, we can treat each emoji as a variable in a system of equations. Let's assign:

Monkey Face = M

Surprise Face = S

Angry Face = A

3 M = 21

M = 21 / 7

= 7

2 S + 7 = 85

2S = 85 - 7

S = 78 / 2

S = 39

3 A + 39 = 162

3A = 162 - 39

A = 123 / 3

= 41

This means that the final value is:

= ( 2 x 39 ) + ( 41 x 3 )

= 78 + 287

= 365
