There's non

=====================================================

Explanation:

According to the table, 10 people have brown eyes. This is out of 1+10+1+1+7 = 20 people total. So 10/20 = 0.50 = 50% of the group has brown eyes.

If this trend holds up, then we expect 50% of the next group of 16 people also have brown eyes.

50% of 16 = 0.50*16 = 8

We expect 8 people to have brown eyes in this next group. This is of course assuming that the first group is unbiased and represents the population (or is close enough).

Answer:

  -35

Step-by-step explanation:

Replace F with -31 and do the arithmetic.

  C = 5/9(-31 -32)

  C = (5/9)(-63) = -35

The temperature in degrees Celsius is -35.

Answer:

The final answer is 78 inches, though I would recommend for you to read through the steps of how this is achieved.

Step-by-step explanation:

To start, to grasp the corresponding sides deal, think of it as saying Quad 1234 is equal to Quad ABCD. Now, it is fairly easy to make up the sides between the two shapes. With this, the following is true:

Side 12 ≅ Side AB

Side 23 ≅ Side BC

Side 34 ≅ Side CD

With the end, it loops back around to meet back at the first edge of the shape again, if you're looking for a side length.

Side 41 ≅ Side DA

Now, with the real stuff. We're greeted with the Quads DEFG and KLMN, and asked to find FG. Looking at it, FG would be using the 3rd and 4th letters of the set of quad edges. Comparing this to the other quad shape, the 3rd and 4th letters are MN. Therefore, lets use this.

Next, set these equal to each other. FG is 5y+3 and MN is 7y-27

5y+3 = 7y-27

5y = 7y-30

-2y = -30

2y = 30

y = 15

y equals 15.

Lastly, plug this into the equation for FG to get the final answer.

5(15)+3

75+3

Step-by-step explanation:

Recursive expressions are ways of expressing sequence using functions. The fifth term of the recursive sequence is 567.

Recursive functions are ways of expressing sequence using functions. Recursive Function is a function that repeats or uses its own previous term to calculate subsequent terms and thus forms a sequence of terms.

here, we have,

given that,

Given the following recursive functions

a₁=7 and;

aₙ = -3aₙ₋₁

For the second term;

a₂ = -3a₁

a₂  = -3(7)

a₂  = -21

For the third term a₃

a₃ = -3a₂

a₃ = -3(-21)

a₃ = 63

For the fourth term

a₄ = 3a₃

a₄ = 3(63)

a₄ = 189

For the fifth term

a₅ = 3a₄

a₅ = 3(189)

a₅ = 567

Hence the fifth term of the recursive sequence is 567.

Step-by-step explanation

Goodbye

A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.

Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder

Answer:

[tex]\angle BPC=100^{\circ}[/tex]

Step-by-step explanation:

Assuming P is the center of the circle:

The angle BPC encompasses arc BC. Notice angle CEB also encompasses this arc and the measure of angle CEB is given as [tex]50^{\circ}[/tex]. The measure of an angle with a point on the circle that encompasses an arc is equal to half of the measure of an angle with a point on the center of circle. Therefore, the measure of arc BPC is equal to [tex]2\cdot50^{\circ}=\boxed{100^{\circ}}[/tex]

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:

[tex]\frac{384}{432}=\boxed{\frac{8}{9}}[/tex]

Hi there!

[tex]200\text{in}^3[/tex]

The formula for volume of a rectangular prism is:

[tex]V = LWH\\\\L-\text{Length}\\W-\text{Width}\\H-\text{Height}[/tex]

Our given measurements are:

[tex]\text{The height of 8 inches.}\\\\\text{The length of 5 inches.}\\\\\text{The width of 5 inches.}[/tex]

Plugging in the values into the formula...

[tex]V = 5 * 5 * 8\\\\\text{Multiply from left to right.}\\\\\rightarrow V=25*8\\\\\rightarrow \boxed{V=200}[/tex]

[tex]\text{The volume of the prism given should be }\boxed{\text{200 cubic inches.}}[/tex]

Hope this helps you. I apologize if it’s incorrect.  

Answer:

Slope = -7/8

Y-intercept = (0, 1)

Step-by-step explanation:

Answer:

[tex]slope = - \frac{7}{8} [/tex]

y- intercept= 1

Step-by-step explanation:

Rearrange the equation such that it is in the form of y=mx+c. This form is known as the slope-intercept form, and m is the gradient while c is the y-intercept.

7x +8y= 8

8y= -7x +8

Divide by 8 on both sides:

[tex]y = - \frac{7}{8} x + 1[/tex]

Thus, the slope is [tex] - \frac{7}{8} [/tex] and the y-intercept is 1.

Another way to find the y-intercept is to substitute x= 0 into the equation since the y-intercept occurs at x= 0.

7x +8y= 8

When x= 0,

7(0) +8y= 8

8y= 8

y= 8 ÷8

y= 1

Thus, the y-intercept occurs at y= 1 or the coordinate (0, 1).

Note: slope and gradient have the same meaning and can be used interchangeably

Answer:

1164.01

Step-by-step explanation:

First you realize there is 6 sides on a hexagon. Then, you divide the 127 by 6. Then you split the hexagons into 6 parts. This leads you to a triangle. Then if you divide the degrees so 360 total degrees/6 parts = 60. If you split that triangle in half, the angle becomes 30 degrees. Then you will realize the 30 degree is pointed at the 127/12. Because you know the x, (x)(Square root 3), 2x theorem (the 30, 60, 90 triangle), you get the height of the triangle which is about 18.33 . Then you do the area of Triangle = 1/2 * base * height. Therefore you should get 194.00 Because there is 6 parts to a hexagon, you then need to multiply by 6. Your final answer should be 1164.01. This should be correct, please correct me if I’m wrong, thanks.

Answer:

0.67 cm/s

Step-by-step explanation:

The area of a square is given by :

[tex]A=x^2[/tex] ....(1)

Where

x is the side of a square

[tex]\dfrac{dA}{dt}=12\ cm^2/s[/tex]

Differentiating equation (1) wrt t.

[tex]\dfrac{dA}{dt}=2x\times \dfrac{dx}{dt}[/tex]

When A = 81cm²​, the side of the square, x = 9 cm

Put all the values,

[tex]12=2\times 9\times \dfrac{dx}{dt}\\\\\dfrac{dx}{dt}=\dfrac{2}{3}\\\\\dfrac{dx}{dt}=0.67\ cm/s[/tex]

So, the length of the side of a square is changing at the rate of 0.67 cm/s.

We can notice from the figure that : Area of the home plate is equal to sum of the Area of the rectangle ( 8 in x 15 in) and Area of the triangle with height 6 in and base 15 in.

Area of the rectangle : Length x Width

⇒  Area of the rectangle = 15 x 8 = 120 in²

Area of the triangle : 1/2 x Base x Height

⇒  Area of the triangle = 1/2 x 15 x 6 = 45 in²

Area of the home plate = Area of rectangle + Area of triangle

⇒ Area of the home plate = 120 in² + 45 in² = 165 in²
