Among the licensed drivers in the same age group, what is the probability that
a 66-year-old was involved in an accident? Use the table below.

Answer:

12x+y

Step-by-step explanation:

12 times a number x

12x

Plus y

12x+y

Answer:

A. x = 2 and y =2

B. x = 3 and y = -1

Step-by-step explanation:

A. { x = 3y − 4

    2x − y = 2

1) Substitute the value of x

2(3y − 4) − y = 2

2) Solve the equation for y

y = 2

3) Substitute the value of y

x= 3(2) -4

4) Solve the equation for x

x = 2

Final Solution: x = 2 and y =2

B. { 3x + 2y = 7

     −x + y = −4

1) Multiply both sides of the equation by 3

-3x + 3y = -12

2) Eliminate one variable by adding the equations

  3x + 2y = 7

+ (−3x + 3y = −12)

   5y = -5

3) Divide both sides of the equation by 5

y = -1

4) Substitute the given value of y into the equation -x + y = -4

-x + (-1) = -4

5) Solve the equation for x

x = 3

Final Solution: x = 3 and y = -1

as x is directly proportional to y

Answer:

31.82% probability that you will receive 2 apples.

Step-by-step explanation:

The fruits are removed from the bag, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

5 + 7 = 12 total fruits, which means that [tex]N = 12[/tex]

7 apples, which means that [tex]k = 7[/tex]

You receive 2 fruits, which means that [tex]n = 2[/tex]

What is the probability, in percent, that you will receive 2 apples, assuming she removes them from the bag in random order?

This is, as a proportion, P(X = 2). So

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 2) = h(2,12,2,7) = \frac{C_{7,2}*C_{5,0}}{C_{12,2}} = 0.3182[/tex]

0.3182*100% = 31.82%

31.82% probability that you will receive 2 apples.

Answer:

2/27

Step-by-step explanation:

First probability = 6/18 = 1/3

second probability = 4/18 = 2/9 (in this case the number of socks remains the same because we returned the first one)

Final probability = 1/3 * 2/9 = 2/27

Step-by-step explanation:

Answer:

Multiply the amount of milk by 4

Step-by-step explanation:

Given

See attachment for graph

Required

The rule of the graph

Pick any two points on the graph

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (1,4)[/tex]

Calculate slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{4 - 0}{1 - 0}[/tex]

[tex]m = \frac{4}{1}[/tex]

[tex]m =4[/tex]

The graph equation is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 4(x - 0) + 0[/tex]

[tex]y = 4(x)[/tex]

[tex]y = 4x[/tex]

The above shows that the x values are multiplied by 4 to get y

Answer:

-4.3 degrees

Step-by-step explanation:

if I understand the problem correctly, then the temperature at midnight fell 15.7 degrees from 11.4 degrees at noon.

11.4 - 15.7 = -4.3 degrees

so, the temperature at midnight was -4.3 degrees

1/6 odds of rolling a 6

1/2 odds of flipping tails

1/6 x 1/2 = 1/12

The probability that she gets a 4 and a tail is 1/12.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

Helen rolls a die and flips a coin.

The probability of getting 4 on the die,

= 1/6

The probability of getting tail on the coin,

= 1/2

The probability that she gets a 4 and a tail,

= 1/2 x 1/6

= 1/12

Therefore, the probability is 1/12.

#SPJ2

Answer:

x ≈ 5.7

Step-by-step explanation:

Recall, SOH CAH TOA.

We are given:

Reference angle = 35°

Opposite side length to reference angle = 4

Adjacent side = x

To find x, apply the trigonometric equation, TOA, which is:

Tan 35° = Opp/Adj

Substitute

Tan 35° = 4/x

x*Tan 35° = 4

x = 4/Tan 35°

x ≈ 5.7

A density curve for all the possible ages between 0 years and 25 years on the shape of a triangle. 0.04

Answer:

the answer is found at option D

Answer:

27 cm²

Step-by-step explanation:

Formula of Area Triangle = 1/2(base x height)

Base = 6 cm

Height = 9 cm

1/2 ( 6 x 9 ) = 1/2 ( 54 ) = 27

Units = cm * cm = cm²

27 cm²

Why the formula (1/2 ( base x height )) works:

Take a triangle

Duplicate the triangle

And rotate the triangle and put it next to the other one

What shape does it form?

Either a parallelogram or a rectangle

The formula for a parallelogram or rectangle is (base x height)

Since you are initially doubling the area of the triangle to get the rectangle, solve for the rectangle and divide by 2.

So, do base x height

And divide by 2

Answer:

[tex]y = -2x - 13[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in slope-intercept formula, is given by:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(value of x when y = 0).

Parallel lines:

If two lines are parallel, they have the same slope.

y = −2x − 5.

This line has slope [tex]m = -2[/tex], which is the same as the line we want to find, as they are parallel. So

[tex]y = -2x + b[/tex]

(−4, −5)

This means that when [tex]x = -4, y = -5[/tex]. We use this to find b. So

[tex]y = -2x + b[/tex]

[tex]-5 = -2(-4) + b[/tex]

[tex]b = -5 - 8 = -13[/tex]

So

[tex]y = -2x - 13[/tex]

Answer:

C + 88 = 180

-88         -88

C and B = 92

Since C is vertical to B that means both values are the same. Therefore the values of c and b is 92 degrees.

Answer:

7

Step-by-step explanation:

7×3=21 (three times the amount)

21+4= 25 (4 more)

25 is the amount of coins that Samuel has. This means that Elizabeth must have 7 coins. This fits the information given.

Answer:

7 coins

Step-by-step explanation:

samuel has 25 , if you multiply the amount elizabeth has by three and add 4 you will get samuels amount so you minus 4 from 25 which is 21 then you divide 21 by 3 which is 7
