Answer:

(6*9)+(4*9.7)=92.8

92.8÷10= 9.28cm

Answer:

0.0776

Step-by-step explanation:

Number of cards = 5 ; 3 red and 2 green

Since it is with replacement :

Probability of picking a replacement d ball: P(red) = required / total possible outcomes

P(red) = 3 / 5 = 0.6

Using binomial :

P(x =x) = nCx * p(x)^x * (1 - p)^(n - r)

P(x = 5) = 5C5 * (0.6)^5 * 0.4^0

P(x = 5) = 1 * 0.07776 * 1

P(x = 5) = 0.0776

[tex]\boxed{\boxed{\pink{\bf \leadsto Yes \ the \ gi en \ sequence \ is \ Arithmetic \ Sequence. }}}[/tex]

Given sequence to us is , 1.1, 1.5, 1.9, 2.3, 2.7, . And we need to find whether they are in arithmetic sequence or not .

Arthemetic Sequence :-

A sequence is said to be in Arithmetic sequence if the difference of two consecutive terms is same. That is constant .

Here if we look at the sequence , 1.1, 1.5, 1.9, 2.3, 2.7, . The diffrence of consecutive terms is same.

That is ,

• 1.5 - 1.1 = 0.4

• 1.9 - 1.5 = 0.4

• 2.3 - 1.9 = 0.4

• 2.7 - 2.3 = 0.4

Hence here the difference of two consecutive terms is same . That is 0.4 .

Answer:

0,4

Step-by-step explanation:

1. 2/5=0,4; 6/15=0,4; 8/20=0,4. It means, the constant of proportionality is 0,4.

2. if the constant value is 0,4, then x:1=0.4 ⇒ x=0,4

Answer:

1) the 5th term is 2401

Answer:

The inequality shown in the graph is y ≤ -3x + 3 ⇒ C

Step-by-step explanation:

The linear form of the equation of a line is y = m x + b, where

From the given graph

∵ The line passes through points (0, 3) and (2, -3)

∴ x1 = 0 and x2 = 2

∴ y1 = 3 and y2 = -3

∵ The slope of the line is m = Δy/Δx

∵ Δx = 2 - 0 = 2

∵ Δy = -3 - 3 = -6

∴ m = [tex]\frac{-6}{2}[/tex]

∴ m = -3

∵ b is value y at x = 0

∴ b = 3

→ Substitute m and b in the form of the equation above

∴ y = -3x + 3

∵ The line is solid and the shading area is under the line

∴ The sign of inequality is ≤ ⇒ (smaller than or equal)

→ Change = in the equation by ≤ to get the inequality

∴ y ≤ -3x + 3

∴ The inequality shown in the graph is y ≤ -3x + 3

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = - [tex]\sqrt{x+11}[/tex] - 3 ← substitute x = - 7

f(- 7) = - [tex]\sqrt{-7+11}[/tex] - 3

       = - [tex]\sqrt{4}[/tex] - 3

       = - 2 - 3

       = - 5 ← output is real

Answer:

the length of the second rectangle is 33.75 in

Step-by-step explanation:

The computation of the length of the second rectangle is as follows

Let us assume the length of the second triangle be x

Now

The equation would be

4 ÷ 15 = 9 ÷ x

Now do the cross multiplication

4x = 15 × 9

4x = 135

x = 33.75 in

Hence, the length of the second rectangle is 33.75 in

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

x² + 9x < -20

Step 2: Solve for x

This tells us that the value of x must be between -5 and -4 in order to render the inequality true.

Answer:

Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.

Step-by-step explanation:

x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.

< means lesser.

> means more than.

A filled up dot means that the number itself is included in the values of x.

A non-filled up dot means that the number itself is not included in the values of x.

An arrow facing left means lesser than that number.

An arrow facing right means more than that number.

Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

Answer:

X : 2__ 3 ___ 5 ___ 6 ___7

Y: 4 __3.5 __2.5___2 __ 1.5

Step-by-step explanation:

Given tbe equation for tbe residual :

y = -0.5x + 5

X : 2, 3, 5, 6, 7

X = 2

Y = - 0.5(2) + 5 = 4

X = 3

Y = - 0.5(3) + 5= 3.5

X = 5

Y = - 0.5(5) + 5 = 2.5

X = 6

y = -0.5(6) + 5 = 2

X = 7

y = -0.5(7) + 5 = 1.5

X : 2__ 3 ___ 5 ___ 6 ___7

Y: 4 __3.5 __2.5___2 __ 1.5

Answer:

[tex]y = 5x[/tex] -- You

[tex]y = 3 + 3x[/tex] --- Your friend

Step-by-step explanation:

Given

You:

Trailhead implies the beginning so:

[tex]Start = 0\ mile[/tex]

[tex]Rate = 5miles/hour[/tex]

Your Friend

[tex]Start = 3\ mile[/tex]

[tex]Rate = 3miles/hour[/tex]

Required

Represent as an equation

From the question, we understand that:

[tex]y = distance[/tex]

[tex]x = number\ of\ hours[/tex]

So, the relationship between [tex]distance\ and\ time\ is:[/tex]

[tex]Distance = Start + Rate * Number\ of\ hours[/tex]

In terms [tex]of\ x\ and\ y[/tex], we have:

[tex]y = Start + Rate * x[/tex]

For you, the equation becomes:

[tex]y = 0+ 5* x[/tex]

[tex]y = 0+ 5x[/tex]

[tex]y = 5x[/tex]

For your friend, the equation becomes:

[tex]y = 3 + 3 * x[/tex]

[tex]y = 3 + 3x[/tex]

Answer:

c. d. different slopes; same y-intercept

for all the equations, when x = 0, y = -2

apart from the last equation which has no x-intercept.

They have different slopes i.e

y=x-2 has a slope of 1

y=2x-2 has a slope of 2

y=x-2 has a slope of 1

y=-2 has no slope

c) x > -3 or x ≤ 2

Step-by-step explanation:

We are asked to solve this algebraic expression

-9 < 4x+3 ≤ 11.

We have two parts:

a) -9 < 4x+3

b) 4x+3 ≤ 11

For

a) -9 < 4x+3

Subtract 3 from both sides

-9 - 3 < 4x + 3 -3

-12 < 4x

-12/4 < x

-3 < x

x > -3

b) 4x+3 ≤ 11

Subtract 3 from both sides

4x + 3 -3 ≤ 11 - 3

4x ≤ 8

x ≤ 8/4

x ≤ 2

Hence, our answer is

x > -3 or x ≤ 2
