Answer:

y = 3x - 1

Step-by-step explanation:

We can manipulate the scatter plot feature in Ms. Excel then we simply add the linear trend line displaying the equation on the chart.

The excel output is attached below.

The relation exhibited by the data set is y = 3x - 1; given the value of x, the value of y is obtained by multiplying x by 3 and subtracting 1 from the result.

The length of an average cat's body is 45 centimeters. How many millimeters are equivalent to 45 centimeters?

Answers

Answer:

450

Step-by-step explanation:

1 centimeter is equivalent to 10 millimeters . Therefore, 45 centimeters will be equivalent to;

45*10 = 450 millimeters

Answer:

450 mm

Step-by-step explanation:

Given in the question,

the length of an average cat's body = 45 cm

To find,

number of mm which are equivalent to 45 cm

We know that

1 cm = 10 mm

45 cm = 45 x 10 mm

           = 450 mm

Hence, there are 450 mm in 45 cm.

What is the slant height x of this square pyramid?

The figure shows a square pyramid. The slant height is shown as a dashed line perpendicular to the base edge and is labeled as x. The length of the lateral edge is 4 meters. The lateral edge makes a 60 degree angle with the base edge.

Answers

Answer:

= 2√3 m  or 3.464

Step-by-step explanation:

Using the sine,  

sin(60”)  = x / 4   multiply both sides by 4

4 sin (60°)   = x

4 * √3 / 2  =  x  

x = 2√3 m  

slant height  =2√3 m

 

Answer: The slant height is 2√3 meters.

Step-by-step explanation: The side adjacent to the 60 degree angle in the right triangle consisting of x, the lateral edge, and half of the base edge is half of the base edge, 2m. The side opposite of that angle is x. So basically you have tan(60°) = x/(2m)*tan(60°) = x = 2√3m. So thus the slant height is 2√3 meters.

Answers

Answer:

x = 15 or x = -17

Step-by-step explanation:

It is given that,

(x + 1)² = 16

To solve the quadratic equation

The give equation is

(x + 1)² = 16    ----(1)

From equation (1) we can see that it is a quadratic equation

So we can take square root fro both sides we get

√[(x + 1)²] =√16

x + 1 = ±16

x + 1 = 16   or x + 1 = -16

x = 16 - 1 = 15   or x = -16 - 1 = -17

Therefore x = 15 or x = -17

3/8 c−2= 3/2 c−12 solve for c

Answers

Final answer:

To solve the equation 3/8c -2 = 3/2c -12 for c, first clear the fractions by multiplying the entire equation by 8. Then, use algebraic operations to isolate and solve for c, yielding the solution c = 80/9 or about 8.89.

Explanation:

The given algebraic equation is 3/8 c−2= 3/2 c−12. Our goal is to solve for c. Here's how:

First, let's multiply the whole equation by 8 to clear out the fractions: 8*(3/8c-2) = 8*(3/2c -12) which simplifies to 3c - 16 = 12c - 96. Next, subtract 3c from both sides of the equation to collect all the terms with c on one side: -16 = 9c - 96. Now, add 96 to both sides to isolate the c term: 80 = 9c. Finally, divide both sides by 9 to solve for c: c = 80/9 or approximately 8.89.

So, the solution to the equation 3/8c - 2 = 3/2c -12 is c = 80/9 or about 8.89.

After simplifying,80/9.

Let's solve the equation:3/8 c−2= 3/2 c−1.

We can solve the equation by combining like terms, eliminating fraction denominators, and distributing.

Steps to solve:

1. Combine multiplied terms into a single fraction:

3/8 c−2= 3/2 c−12

2. Find common denominator:

3/8 c + (8/8) −2= 3/2 c−12

3. Combine multiplied terms into a single fraction:

3/8 c + (8 *(−2) /8) −2= 3/2 c−12

4. Combine fractions with common denominator:

(3c + 8 *(−2) /8) = 3/2 c−12

5. Multiply the numbers:

(3c -16) /8) = 3/2 c−12

6.Combine multiplied terms into a single fraction:

9.Multiply the numbers:

(3c -16) /8) =(3c -24) /2)

10. Eliminate fraction denominators:

8*(3c -16) /8) = 8*(3c -24) /2)

11. Cancel multiplied terms that are in the denominator:

3c−16=4(3c−24)

12. Distribute:

3c−16=12c−96

13. Add/subtract to both sides:

3c−16+16=12c−96+16

14. Simplify:

3c=12c−80

15. Add/subtract to both sides:

3c−12c=12c−80−12c

So if 2 notebooks cost 12 divide that

So to check if its true the 3notebooksx $6 dollars each should =$18 for 3 notebooks
5 notebooks at $6 each = $30 for 5 notebooks
so What is 4notebooks x$6 each ? =4x6 = $24 for 4 notebooks

The cost of 4 notebooks should be 24.

What is proportion?

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

Given that,

Price of 2 notebooks = $12

Price of 3 notebooks = $18

And the price of 5 notebooks = $30

To determine the price of 4 notebooks,

First find the price of 1 notebook = 12 / 2 = 6

The price of 4 notebooks = 6 x 4 = 24

The required price of 4 notebooks is $24.

Answers

Answer:

765

Step-by-step explanation:

Given in the question,

number of people to be choose with at least 5 women in it = 8

There are 2 ways to choose 8 members

1)

5 women

(6C5)(10C3)

6x120

720

2)

6 women

(6C6)(10C2)

1x45

45

Our final answer is 720 + 45 = 765 ways

Formula to calculate

nCr = n! / r!(n-r)!

The selection of members of the committee is an illustration of combination.

The number of ways of selection is 765

The given parameters are:

[tex]\mathbf{Men = 10}[/tex]

[tex]\mathbf{Women = 6}[/tex]

At least 5 women means that:

There are 5 women and 1 man in the committee orThere are 6 women and no man in the committee

So, the possible selection is:

[tex]\mathbf{Selection = ^6C_5 \times ^{10}C_3 + ^6C_6 \times ^{10}C_2}[/tex]

Apply combination formula

[tex]\mathbf{Selection = \frac{6!}{5!1!} \times \frac{10!}{7!3!} + \frac{6!}{6!0!} \times \frac{10!}{8!2!}}[/tex]

[tex]\mathbf{Selection = 6 \times 120 + 1 \times 45}[/tex]

You are re-tiling the entry to your home and want to create a fancy circular medallion in the center. You want to create a large circle with a smaller circle centered inside. You want to tile the large circle with blue tile and the smaller circle with yellow tile. The circumference of the large circle is 113.097 inches and the radius of the smaller circle is 7 inches. How much blue tile do you need (in square inches)?


Answers

Answer:

Are needed [tex]863.5\ in^{2}[/tex] of blue tile

Step-by-step explanation:

we know that

To find how much blue tile do you need, subtract the area of the smaller circle from the area of the large circle

step 1

Find the radius of the large circle

The circumference of the circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]C=113.097\ in[/tex]

substitute and solve for r

[tex]113.097=2\pi r[/tex]

[tex]r=113.097/(2\pi)[/tex]

assume

[tex]\pi=3.14[/tex]

[tex]r=113.097/(2(3.14))=18\ in[/tex]

step 2

Find the area of the large circle

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=18\ in[/tex]

substitute

[tex]A=\pi (18)^{2}=324\pi\ in^{2}[/tex]

step 3

Find the area of the smaller circle

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=7\ in[/tex]

substitute

[tex]A=\pi (7)^{2}=49\pi\ in^{2}[/tex]

Answer:

15. 31.42 cm^2

16. 25.73 m^2

17. Fly A

Step-by-step explanation:

15.

The blue shaded region is a sector of a circle. The formula for area of sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]

Where  [tex]\theta[/tex] is the central angle and r is the radius

For the diagram, we have 80° arc and 180° arc as the "white" area. Since the whole circle is 360°, the shaded region arc is 360 - (80+180) = 100°. this is  [tex]\theta[/tex] and the radius is 6.

Plugging in it in the formula we get:

Area of shaded region = [tex]\frac{\theta}{360}*\pi r^2\\=\frac{100}{360}*\pi(6)^2\\=31.42[/tex] cm^2

16.

We can say that area of shaded region = area of parallelogram - area of circle

Now,

Area of Parallelogram = b * h

where

b is the base (it is 6+3=9) and h is the height (diameter of the circle is the height = 6)

Area of Parallelogram = 9 * 6 = 54

Area of Circle = πr^2   where r is the radius, which is 6/2=3

Area of Circle = π(3)^2 = 9π

Now,

Area of Shaded Region = 54 - 9π = 25.73 m^2

17.

For the first figure (rectangle) we could let the height be h (since not given). So area of yellow region would be 4h (area of rectangle is base * height)

And area of whole ruler would be 8*h = 8h

So probability of landing in yellow region would be  [tex]\frac{4h}{8h}=\frac{1}{2}=0.5[/tex]

For 2nd figure, the yellow region has area of π(2)^2 = 4π ( radius of yellow circle is 2 and area of circle is πr^2)

Area of whole circle is  π(4)^2 = 16π

So probability of landing in yellow region would be  [tex]\frac{4\pi}{16\pi}=\frac{1}{4}=0.25[/tex]

Hence, Fly A is more likely to land in a yellow region.
