Using probability concepts, it is found that: 0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.

-----------------------------

I am going to treat the probabilities of these events as Venn probabilities, stating that:

-----------------------------

-----------------------------

The probability of chalk or plant is:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

From the bullet points:

[tex]P(A \cup B) = 0.3 + 0.6 - 0.2 = 0.7[/tex]

0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.

The required formula to find the number of students who attended the fourth meeting is 80 = 56 + x

Using the mean formula, the number of students who attended the fourth meeting is 24

Formula to obtain the mean :

Mean = ΣX/ n

X = number of students that attended each meeting

n = number of meetings

X = meeting 1 + meeting 2 + meeting 3 + meeting 4

n = 4

Mean = 20

Let number of students who attended 4th meeting = x

Mean = ΣX/ n

20 = (18 + 21 + 17 + x) / 4

80 = 56 + x

x = 80 - 56

x = 24

Hence, 24 students attended the fourth meeting.

Answer:

t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))

Step-by-step explanation:

Solve for t:

z = (h t^2)/2 + t q_1

z = (h t^2)/2 + t q_1 is equivalent to (h t^2)/2 + t q_1 = z:

(h t^2)/2 + t q_1 = z

Divide both sides by h/2:

t^2 + (2 t q_1)/h = (2 z)/h

Add q_1^2/h^2 to both sides:

t^2 + (2 t q_1)/h + q_1^2/h^2 = (2 z)/h + q_1^2/h^2

Write the left hand side as a square:

(t + q_1/h)^2 = (2 z)/h + q_1^2/h^2

Take the square root of both sides:

t + q_1/h = sqrt((2 z)/h + q_1^2/h^2) or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)

Subtract q_1/h from both sides:

t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)

Subtract q_1/h from both sides:

Answer: t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))

Sometimes, two similar or congruent objects may be regarded as having a different shape if a reflection is required to transform one into the other. For instance, the letters " b " and " d " are a reflection of each other, and hence they are congruent and similar, but in some contexts they are not regarded as having the same shape.

Step-by-step explanation:

Objective; Translating points

A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.

Algebracially:

[tex](x + h)[/tex]

where h is the amount of units we move right or left

and

[tex](y + k)[/tex]

where k is the amount of units we move up or down

For 1. We are asked to translate the figure 3 units up and 7 units to the left.

7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is

Our new coordinates

E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).

2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.

So our new coordinates is

T' (1,3)

U' (4,3)

V'(4,5)

W'(1,5)

Answer:

512 is the minimum sum of the squares, when both numbers are 16.

Step-by-step explanation:

Make the two numbers equal. 16² + 16² = 256 + 256 = 512

Make the two numbers as far away as possible. 32² + 0² = 1024 + 0 = 1024.

The two numbers are 18 and 18 and the sum of their squares is 648 which is the minimum

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be = x

Let the second number be = 36 - x

Now ,

The sum of two numbers = 36

So ,

For both the numbers to be in their minimum value , the number will be half the original number

So ,

2x = 36

Divide by two on both sides , we get

x = 18

So , the two numbers are 18 and 18

Now ,

The sum of the squares of numbers A should be minimum ,

So ,

A = 18² + 18²

A = 324 + 324

A = 648

Therefore , the sum of the squares of two numbers is 648

Hence , The two numbers are 18 and 18 and the sum of their squares is 648 which is the minimum

Step-by-step explanation:

this is in the simplest form

Step-by-step explanation:

BCD = 180- 100 = 80

the opposite angles of a parallelogram are of equal measure

SO DAB = X = 80

The sum of all parallelogram angles = 360

360 - 160 = 200

200 equals the measure of angle ADC + ABC

ABC = ADC

200 = 2ABC

ABC = 100

ADB = DBC = 30

Y = 100 - 30 = 70

another way to find y is using the rule that says that the sum of the triangle ADB angles = 180

180 = 80 + 30 + y

y = 70
