Common difference is 3
Zielflug [23.3K]3 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 8 - 5 = 11 - 8 = 14 - 11 = 17 - 14 = 20 - 17 = 23 - 20 = 3

This indicates the sequence is arithmetic

The common difference d = 3

The first term a₁ = 5 and

a₈ = 23 + 3 = 26

Natasha2012 [34]

Answer:

median = 7

Step-by-step explanation:

The median is the middle value of the data set arranged in ascending order

2, 2, 2, 2, 3, 5, 7, 9, 9, 10, 11, 12, 18

                        ↑ middle value

1. Thom has a scale model of his car. The
MariettaO [177]

x =\frac{4}{3}inch is the size in wheels on the scale model .

<u>Step-by-step explanation:</u>

Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?

We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:

Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,

⇒ \frac{1}{12}  = \frac{x}{16}                 { x is size of wheel in scale model }

⇒ \frac{1(16)}{12}  = \frac{x}{16}(16)

⇒ x =\frac{16}{12}

⇒ x =\frac{4}{3}inch

Therefore , x =\frac{4}{3}inch is the size in wheels on the scale model .

thank you for hurrying here is the very last one Explain how you would find the perimeter of this triangle.
Lena [83]

Step-by-step explanation:

Use the method of TOA CAH SOH.

tan(51.3) =  \frac{opp}{adj}  \\  \tan(51.3)  =  \frac{u}{4}  \\ u = 4 \tan(51.3)

cos(51.3)  =  \frac{adj}{hypo}  \\  \cos(51.3)  =  \frac{4}{v}  \\ v \cos(51.3)  = 4 \\ v =  \frac{4}{ \cos(51.3) }

Perimeter of triangle = Sum of all sides =

u \:  +  \: v + 4

Suppose xy &gt; 0. Describe the points whose coordinates are solutions to the inequality.
Elan Coil [88]

The solutions fo the inequality are all the points (x, y) that meet these 3 conditions.

  • x ≠ 0
  • y ≠ 0
  • Sign(x) =sign(y)

<h3>Which points are solutions of the inequality?</h3>

We want to find points of the form (x, y) that are solutions of the inequality:

x*y > 0

Clearly x and y must be different than zero.

So, for example if x = -1, y can be any negative number, for example y= -3

x*y > 0

(-1)*(-3) > 0

3 > 0

This is true.

Now if x  = 1, y must be positive. LEt's take y = 103, then:

x*y > 0

1*103 > 0

103 > 0

Then we have 3 conditions:

  • x ≠ 0
  • y ≠ 0
  • Sign(x) =sign(y)

The solutions fo the inequality are all the points (x, y) that meet these 3 conditions.
