The probability of ending up with an orange hat is 1/12. It is because here are twelve possible outcomes.

Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.

It is represented mathematically as;

Probability = Number of Expected outcomes / Total number of outcomes

From the question, we can have the following outcomes;

Clothing = 4

Colors = 3

Pr (pick a clothing) = 1/4

Pr (pick a color) = 1/3

Pr (picking an orange hat) = 1/4 x 1/3

Pr (picking an orange hat) = 1/12.

Step-by-step explanation:

Multiple according to the number 3 is 162 and its submultiple according to the number 7 is 7.

What is called multiplication?

Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. In math, multiply means the repeated addition of groups of equal sizes.

Given that :

One segment measures 161 cm

To find the multiple according to the number 3, divide 161 by 3.

161 ÷ 3 = 53.67

Nearest integer of 53.67 is 54

The multiple according to the number 3 = 54 × 3

                                                                   = 162

To find the submultiple according to the number 7, divide 161 by 7.

161 ÷7 = 23

Nearest integer of 23 is 23

The submultiple according to the number 7 = 161 ÷ 23

                                                                          = 7

Multiple according to the number 3 is 162 and its submultiple according to the number 7 is 7.

As per the unitary method, the number would you expect to be confirmed for MDD at the follow-up visit is approximately 166.

The term unitary method in statistics refers a basic concept to find the value of a single unit and then using that value to find the value of multiple units.

Here we have to find how many of your 500 clients would you expect to have major depressive disorder and  if you used the phq-2 to screen for MDD, what number of those who are depressed would screen positive.

In order to find the number of patients with MDD, we must know the process of PHQ - 2.

The process of PHQ - 2 involves the following steps:

Here the score ranges from 0-6.

And if the score is 3 or greater, then major depressive disorder is likely.

Based on these we have to test the 500 with PHQ test, let us consider that there is 2 person in every two person has MDD.

So, the number of MDD patient is approximately 166.

Step-by-step explanation:

1.

it is always the same.

the usual equation of a line is

y = ax + b

"a" being the slope, "b" being the y-intercept (the y-value when x = 0).

we see that the y-value is +3 when x = 0. that is "b".

for the slope we pick 2 points (with integer coordinates, if possible).

I see e.g. (0, 3) and (3, 0)

x changes by +3 (from 0 to 3).

y changes by -3 (from 3 to 0).

the slope "a" is -3/+3 = -1

the equation is

y = -x + 3

2.

and again the same

we see that the y-value is -3 when x = 0. that is "b".

I see e.g. (0, -3) and (3, 0) as points.

x changes by +3 (from 0 to 3).

y changes by +3 (from -3 to 0).

the slope "a" is +3/+3 = 1.

the equation is

y = x - 3

Answer:

To find the area of a triangle, we can use the formula:

Area = (base * height) / 2

To find the area of triangle ABC, we first need to find the base and the height.

Since angle B is 75 degrees, we can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle A: 180 - 75 - 90 = 15 degrees.

Then, we can use the fact that the measure of an angle in a triangle is proportional to the length of the side opposite that angle to find the length of side AC:

AC/AB = m∠A/m∠B

AC = (m∠A/m∠B) * AB

Substituting, we get:

AC = (15/75) * 12 = 3

Now that we know the base and the height of the triangle, we can use the formula to find the area:

Area = (3 * 12) / 2 = 18

Therefore, the area of triangle ABC is 18 square cm.

Answer:

Step-by-step explanation:

If the car holds at most 14.5 gallons of gas and you use 1.5 gallons of gas on the way to the grocery store, the amount of gas you have left in your tank can be represented by the inequality:

[tex]14.5 - 1.5 < = x[/tex]

This inequality can be read as "14.5 minus 1.5 is less than or equal to the amount of gas you have left in your tank, x."

Solving for x, we get:

[tex]x > = 13[/tex]

So the amount of gas you have left in your tank is greater than or equal to 13 gallons.

To find the total mass of all the worker bees in the hive, you need to multiply the mass of a single worker bee by the number of worker bees in the hive.

The mass of a single worker bee is 2 x 10^-4 kilograms, and there are 8 x 10^4 worker bees in the hive.

So the total mass of all the worker bees in the hive is (2 x 10^-4 kilograms) * (8 x 10^4 worker bees) = 0.16 kilograms.

In standard form, this is written as 1.6 x 10^-1 kilograms.

The linear equation that represents the plant height is the one in the first option:

y = 14 + (3/2)x

We know that the initial height of the plant (this will be the y-intercept of the line) is 14cm, and we also know that the plant grows at a rate of 3/2 cm each day.

So, after x days, the plant is x times 3/2cm plus 14 cm of height, so the linear equation is:

y = 14 + (3/2)x

In terms of b, the perimeter expression is 6 + 4b and the value of b is 9

From the question, we have the following parameters that can be used in our computation:

Dimensions = 8cm and 2b - 5 cm

The above parameters mean that

Length = 8

Width = 2b - 5

The perimeter is calculated as

Perimeter = 2 * (Length + Width)

Substitute the known values in the above equation, so, we have the following representation

Perimeter = 2 * (8 + 2b - 5)

Evaluate the like terms

Perimeter = 2 * (3 + 2b)

Open the brackets

Perimeter = 6 + 4b

Here, we have

Perimeter = 42

This means that

6 + 4b = 42

So, we have

4b = 36

Divide by 4

b = 9

Hence, the value is 9

5x = y - 25

y = 5x + 25

Substituting this value of y into the first equation, we get:

60x + 25 = 5x + 25

55x = 0

x = 0

This means that Liza will pass Ralph 0 hours after she leaves, or at the same time as Ralph. At this time, they will have both traveled 0 miles.

The point where the tangent to the given equation is horizontal is [tex](x, y) = (-2, -5)[/tex].

To find the tangent of a curve, we have to find the first derivative of the function. Hence, the tangent of the given curve is given by

⇒ [tex]f'(x) = \frac{d{f(x)}}{dx} = \frac{d{x^{2}}}{dx} + \frac{d(4x)}{dx} - \frac{d(1)}{dx}[/tex]

⇒ [tex]f'(x) = 2x + 4[/tex]

Now, as the tangent is horizontal, that means the slope of the tangent is 0, hence setting [tex]f'(x) = 0[/tex] , we get the equation

⇒ [tex]f'(x) = 2x + 4 = 0[/tex]

Solving the equation obtained for the variable x,

⇒ [tex]2x = -4\\[/tex]

⇒ [tex]x = -2[/tex]

Now, putting the obtained value for x in the original equation, we get

The proportionality used in the given diagram is 4/3=12/x if ΔABC and ΔDEF are similar. So, option 4 is correct.

Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.

In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle. If and only if all geometry is the Euclidean plane, all triangles are contained in a single plane; however, this is no longer true in higher-dimensional Euclidean spaces. The topic of this article, unless otherwise stated, is triangles in Euclidean geometry, specifically the Euclidean plane.

We have to assume that ΔABC and ΔDEF are similar.

If the triangles are similar,

Then the proportionality is:

AB/BC=DE/EF

4/3=12/x
