The probability of the event that all three are blue is 1/455 or 0.0022

In probability theory, the probability of an event is a measure of the likelihood that the event will occur. It is a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be expressed as a decimal, a fraction, or a percentage.

Probability is used to quantify the uncertainty associated with a random event. It is based on the idea that if an experiment is repeated many times under the same conditions, the proportion of times the event of interest occurs will be close to the probability of that event.

The probability of an event can be calculated using the following formula:

Probability of an event = Number of favorable outcomes / Total number of possible outcomes

In this problem, we can define our variables.

Total number of possible outcomes = 15

P(All three are blue) = (3/15) * (2/14) * (1/13)

P(All three are blue) = 1/455

P(all three are blue) = 0.0022

Answer:

D

Step-by-step explanation:

the area (A) of Δ CDE is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 8 and h = 6 , then

A = [tex]\frac{1}{2}[/tex] × 8 × 6 = 4 × 6 = 24 cm²

Δ CDE and Δ ABCare similar ( AA postulate )

given the scale factor of 2 similar figures is k

then the factor of their areas is k²

here the scale factor k of the 2 triangles is the ratio of corresponding sides , Δ CBA to Δ CDE , then

k = [tex]\frac{AB}{CD}[/tex] = [tex]\frac{12}{8}[/tex] = 1.5

then the ratio of their area is 1.5² = 2.25

that is area of Δ ABC is 2.25 times area of Δ CDE

area o Δ ABC = 2.25 × 24 cm² = 54 cm²

then 54 cm² - 24 cm² = 30 cm²

Thus

area of Δ ABC is 30 cm² greater than Δ CDE

The required equation of the line is y = -3x +11 which passes through the points (2, 5) and (5, -4)

The slope is simply expressed as an inclination of the line in the coordinate system.

Slope m = (y₂ - y₁) / (x₂ - x₁)

Given that the line that passes through two points (2, 5) and (5, -4)

Let x₁ = 2, y₁ = 5 and x₂ = 5, y₂ = -4

The required equation of the line is

y - y₁  = {(y₂ - y₁ )/( x₂ - x₁ )}( x - x₁ )

Substitute the values in the formula to get the slope of the line,

y - 5 = {(-4 - 5 )/( 5 - 2)}(x - 2)

y = {( -9 )/( 3 )}(x - 2) + 5

y = -3x + 6 + 5

y = -3x +11

Therefore, the required equation of the line is y = -3x +11

Answer:

D

Step-by-step explanation:

Let's say the number of adults who brought 3 children each is x. So the number of adults who brought 2 children each is 100-x.

Then the total number of children is 3x + 2(100-x) = 300 + x.

The total amount of money made from adults is 60 * 100 = 6000.

The total amount of money made from children is 30 * (300 + x) = 9000 + 30x.

So 6000 + 9000 + 30x = 25800

=> 15000 + 30x = 25800

=> 15000 = 25800 - 30x

=> 15000 = 25800 - 30x

=> 30x = 10800

=> x = 360

So the number of adults who brought 3 children each is 360 and the number of adults who brought 2 children each is 100-360 = -260 (which is not possible).

So the answer is D) None of these.

To solve the problem, set up equations using the given information. Substitute the value of one variable into the other equation to solve for both variables. Then use the values to find the number of children and adults.

To solve this problem, we can start by setting up equations based on the given information. Let's denote the number of adults as A and the number of children as C. We know that each adult brought either 3 children or 2 children, resulting in a total ticket sales of R25800.

So we can set up the following equation: 30C + 60A = 25800.

We also know that there were 100 adults. If each adult brought 3 children, then the total number of children would be 3 times the number of adults: C = 3A.

Substituting the value of C from the second equation into the first equation, we get 30(3A) + 60A = 25800. Solving this equation will give us the values of A and C.

Answer:

the answer for 2 examples is in the picture

Therefore , the solution of the given problem of linear equation comes out to be x= 2 and y=0.

A model of linear regression is one that applies the formula y=mx+b. B is the slope, and m is the y-intercept. Despite the fact because both y and x are distinct components, the previous sentence is frequently referred to it as a "mathematical formula with two variables." Bivariate linear equations only have two variables. The application domains of linear equations have zero solutions in all cases. The equation for a solitary linear equation is Y=mx+b, where m stands for the elevation and b for the y-intercept. Y=mx+b, where m stands for slopes and b for the y-intercept, is how the equation is expressed.

Here,

Given :

=> y = 4x -8

=> 4y=4x−8 ​ or y = x -2

So,

=> y =4x-8

Thus,

=> 4x -8 = x-2

=> 3x =6

=> x =2

and

=> y = 8-8 =0

Therefore , the solution of the given problem of equation comes out to be x= 2 and y=0.

Step-by-step explanation:

if its given they got a B then that means you have to take how many females divided by the total number of people who got B's.

Therefore, 20/34.

Which can simplified to 10/17.

The equation that represents the given situation is; 10 + 2.25x = 39.25

The following are in the question;

One time donation = $10

Hourly donation = $2.25

Total donation = $39.25

Number of hours = x

Thus, the required equation is:

10 + 2.25x = 39.25

Solving for x:

Subtract 10 from both sides;

2.25x = 39.25 - 10

2.25x = 29.25

x = 29.25/2.25

x = 13

The probability that a car selected at chance is moving at more than 70mi/hr is 0.02

Normal usually refers to the word "normal" in a normal distribution.

The word normal is used when something occurs that has occurred frequently. The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from the mean, its chances decrease.

Since the speeds of cars are normally distributed, is expressed as

z = (x - µ)/σ

Where x = speeds of cars

µ = mean speed

σ = standard deviation

From the information given,

µ = 60 mi/hr

σ = 5 mi/hr

Here we want to find the range of the function:

f(x) = 12 - 3x

f(-4) = 12 - 3*(-4) = 24

f(-2) = 12 - 3*-2 =  18

f(0) = 12  -3*0 = 12

f(2) = 12 - 3*2 = 6

Answer:

m∠2 = 35° and m∠3 = 55°

Step-by-step explanation:

∠3 + ∠4 = 90° as shown with the square marking on the other side.

∠3 + 35° = 90°, 90°- 35° = ∠3

∠3 = 55°

∠1 = 90°, ∠3 = 55°, ∠2 = ?

A triangle's interior angles always add up to 180°.

90° + 55° + ? = 180°

145° + ? = 180°

? = 180° - 145°

? = 35°

The relationship between one group of stimuli, each of which has a related output, is referred to as a "function." A function is a relationship between the inputs and outputs where each input produces a single, unique result. Every function has a domain but a codomain, often known as a scope. F is typically used to signify functions (x). An x is the input.
