Answer:

  A

Step-by-step explanation:

Your friendly local graphing calculator or spreadsheet can tell you the quadratic regression equation. It best matches choice A.

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.

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

Answer:

the answer is found at option D

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

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:

x is equal to -4

Step-by-step explanation:

4x+3= -13

4x/4= -16/4

x= -4

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

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

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:

P = 1 / 40320       or   P  = 2.48*10⁻⁵

Step-by-step explanation:

The total number of outcomes To is:

To  =  8!       To  =  8*7*6*5*4*3*2

To  =  40320

Of all these outcomes there is only one proper outcome, therefore the probability of having all men and women in alphabetical order is:

P = 1 / 40320       or   P  = 2.48*10⁻⁵

Step-by-step explanation:

Answer:

x=KY

as x is directly proportional to y

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:

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

There is an open circle at 2 and the lines goes to the right

Answer:

Th correct option is (d).

Step-by-step explanation:

The given expression is :

[tex]16x^2 + nx + 49[/tex] ....(1)

We know that, 16 = 4² and 49 = 7²

Also, (a+b)² = a²+2ab+b²

The given expression becomes,

[tex]16x^2 + nx + 49=(4x)^2+nx+7^2\\\\=(4x)^2+2(4x)(7)+7^2\\\\=16x^2+56x+49\ ......(2)[/tex]

Comparing equations (1) and (2),

n = 56

Hence, the value of n is equal to 56.

Second choice.

Which is 1591.1 cm^2.

Answer:

66.32

Step-by-step explanation:

Hello!

[tex]\large\boxed{66.32 m}[/tex]

We are given the area, so we can solve for the width given the length:

A = l × w

Thus:

272.4 = 15 × w

w = 18.16 m

The perimeter of a rectangle can be calculated using this equation:

P = 2l + 2w

Therefore:

P = 2(15) + 2(18.16)

P = 30 + 36.32 = 66.32m
