The people who responded to a survey reported that they had either brown, green, blue, or hazel eyes. The results of the survey are shown in the table. What is the probability that a person chosen at random from this group has brown or green eyes?

Answer:

8.717 both the sides

Step-by-step explanation:

Given:

Let ABC be the given triangle with

angle A= 55

angle B=55

angle C= 70

side across angle C, c= 10 inches

side across angle B, b =?

aide across angle A,a=?

Now using the law of sin to find a and b:

                a/sinA=c/sinC

                a= (c/sinC)(sinA)

Putting the values:

                a= (10/sin70)(sin55)

                a= 8.717

As the given triangle is isosceles so side a=b

hence a=b= 8.717 inches !

[tex]\large\boxed{Q6.\ \sin X\approx0.778}\\\boxed{Q7.\ x\approx5.9}[/tex]

Step-by-step explanation:

Q6.

[tex]\sin\theta=\dfrac{opposite}{hypotenuse}[/tex]

We have

[tex]opposite=14\\\\hypotenuse=18[/tex]

Substitute:

[tex]\sin X=\dfrac{14}{18}=\dfrac{14:2}{18:2}=\dfrac{7}{9}=0.777...\approx0.778[/tex]

Q7.

Use sine.

We have

[tex]opposite=x\\\\hypotenuse=8\\\\\alpha=48^o\\\\\sin48^o\approx0.7431[/tex]

Substitute:

[tex]\dfrac{x}{8}=0.7431[/tex]               multiply both sides by 8

[tex]x=5.9448\to x\approx5.9[/tex]

Answer:

128

Step-by-step explanation:

Method A.

The volume of the prism is 2 cubic units.

Each cube has side length of 1/4 unit.

The volume of each cube is (1/4)^3 cubic unit.

The volume of each cube is 1/64 cubic unit.

To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.

(2 cubic units)/(1/64 cubic units) =

= 2/(1/64)

= 2 * 64

= 128

Method B.

Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128

He right answer is 128

Step-by-step explanation:

To obtain the next term in a geometric sequence multiply the previous term by r

Given

a₁ = - 7 and r = - 4, then

a₂ = - 7 × - 4 = 28

a₃ = 28 × - 4 = - 112

Answer:

y = (-5/4)x + 12.25

Step-by-step explanation:

Slope intercept form:

y = mx + b

Slope form:

m = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (9 , 1)

(x₂ , y₂) = (5 , 6)

Plug in the corresponding numbers to the corresponding variables.

m = (6 - 1)/(5 - 9)

Simplify.

m = (5)/(-4)

Your slope is -5/4

Plug in -5/4 for m in the slope-intercept form equation, and use a point to solve for b. For example, we will use (9, 1):

y = mx + b

y = (-5/4)x + b

(1) = (-5/4)(9) + b

Simplify.

1 = (-11.25) + b

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Add 11.25 to both sides.

1 + (11.25) = -11.25 (+11.25) + b

1 + 11.25 = b

b = 12.25

your y-intercept is 12.25

Plug in the corresponding numbers to the corresponding variables.

y = mx + b

m = -5/4

b = 12.25

y = (-5/4)x + 12.25 is your answer.

Final answer:

To find w from the equation 3w - 4z = 8, add 4z to both sides, and then divide by 3 to isolate w, giving w = (4z + 8) / 3.

Explanation:

The equation 3w - 4z = 8 is a linear equation in two variables (w and z). To find w in terms of z, you need to isolate w on one side of the equation. Here is the process step by step:

Add 4z to both sides of the equation: 3w - 4z + 4z = 8 + 4z.

Simplify the equation: 3w = 4z + 8.

Divide every term by 3 to solve for w: w = (4z + 8) / 3.

So, w is equal to (4z + 8) / 3 when isolated from the given equation.

What is segment ab? is there a picture that is supposed to go with it?

Answer:  The required co-ordinates of point M are (8, 9).

Step-by-step explanation:  Given that the point M divides segment AB into a ratio of 2 : 3, where A is at (0, 15) and B is at (20, 0).

We are to find the co-ordinates of point M.

We know that

the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) are given by

[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]

For the given division, (a, b) = (0, 15), (c, d) = (20, 0) and m : n = 2 : 3.

Therefore, the co-ordinates of point M are given by

[tex]\left(\dfrac{2\times20+3\times0}{2+3},\dfrac{2\times0+3\times15}{2+3}\right)\\\\\\=\left(\dfrac{40}{5},\dfrac{45}{5}\right)\\\\\\=\left(8,9).[/tex]

Thus, the required co-ordinates of point M are (8, 9).

The answer is C. C is not a proportion.

Hope this helps!

Answer:

C

Step-by-step explanation:

By definition a proportion should be equal to each other and can be multiplied by the same number on the numerator and the denominator to make the second fraction.

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

[tex]\frac{x_1}{y_1}*\frac{z}{z}=\frac{x_2}{y_2}[/tex]

A

[tex]\frac{3}{7}*\frac{3}{3}=\frac{9}{21}[/tex]

So it is a proportion.

B

[tex]\frac{24}{56}/\frac{8}{8}=\frac{3}{7}[/tex]

So it is a proportion.

C

[tex]\frac{3}{7}*\frac{3}{4}=\frac{9}{28}[/tex]

So it is not a proportion.

D

[tex]\frac{3}{7}*\frac{4}{4}=\frac{12}{28}[/tex]

B. The two middle coefficients add to the correct number but do not multiply to the correct number.

EXPLANATION

The given quadratic trinomial that Tina tries to factor is

[tex]10 {x}^{2} - 13x - 3[/tex]

Comparing to

[tex]a{x}^{2} + bx + c[/tex]

we have a=10, b=-13 and c=-3

ac=-3×10=-30

We split the middle term so that their sum is -13.

Tina use

-10,-3

to get

-10x-3x

The sum is -13x alright but the product is not -30.

B is correct.

A slope is also known as the gradient of a line. The correct option is B.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The slope of the line that is passing through (-2, 6) and (4, 6) can be calculated as,

Slope = (6-6)/(-2-4) = 0/(-6)

Hence, there exists no slope between the two of the given points.
