Complete question :

Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid between 15500 and 17000

Answer:

49.85%

Step-by-step explanation:

Mean = 17000

Standard deviation = 500

Obtain the Z score, which is the number of standard deviations from the mean :

((17000 - 17000) / 500) = 0

((15500 - 17000) / 500) = - 3

-3 to 3 = (3 standard deviations)

However,

The value here is (-3 to 0) ; which is only 3 standard deviations to the left.

3 standard deviation = 99.7% (empirical rule)

Since it is only (-3 to 0) ; which is only 3 standard deviations to the left. ; the percentage will be halved

99.7% / 2 = 49.85%

Hence, percentage of buyers who paid between 15500 and 17000 is 49.85%

Answer:

360 cubic units

Step-by-step explanation:

height = 4 units

length = 10 units

breadth = 6 units

Volume of a cuboid = l × b × h

V = 10 × 6 × 4

V = 10 × 24

V = 240 cubic units

Now a scale factor of 1.5 units is applied to the dimensions,

new volume = 240 × 1.5 = 360

∴ New volume of the prism = 360 cubic units

Answer:

240 cubic units

Answer:

x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.

Step-by-step explanation:

(x3 + 2x - 1)  (x4 - x3 + 3)

= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3

= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.

The expression represents the product [tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]

We have given that,

[tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.

[/tex][tex](x^3 + 2x - 1) (x^4 - x^3 + 3)[/tex]

The expression consists of numbers and arithmetic operators.

It does not contain equality or inequality symbols.

The expression consists of unknown variables.

The expression represent the product of [tex]x^3 + 2x - 1[/tex]and [tex]x^4 - x3 + 3[/tex][tex]= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3[/tex][tex]= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]

Therefore, The expression represents the product [tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]

Answer:

I'm not to sure about which one is 11 but the answer is B.

Step-by-step explanation:

1/2

Step-by-step explanation:

there are two numbers 3 and 6 so 2/6 is 1/3

Answer:

Answer B

Step-by-step explanation:

You have to use the pythagorean theorm which states that a^2+b^2=c^2

So, 7^2+x^2=9^2

49+x^2=81 subtract 49 from both sides of the equation

x^2=32

x=sqrt(32)

sqrt(32)=sqrt(16)*sqrt(2)

=4*sqrt(2)

Answer:

B. (1, 2)

Step-by-step explanation:

In a function, each value used in as an x-coordinate can be used only once.

Values already used as x-coordinates: -3, 8, 0, -5

The answer cannot have -3, 8, 0, or 5 as an x-coordinate.

The only choice without one of those four values as an x-coordinate is (1, 2).

Answer: B. (1, 2)

Answer:

B

Step-by-step explanation:

-5 is already used

-3 is already being used

0 is already being used

Every x value can only be itself once

Answer:

[tex]A = 54[/tex]

Step-by-step explanation:

Given

[tex]\sin A = \cos B[/tex]

[tex]A=1.5B[/tex]

Required

Find A

If [tex]\sin A = \cos B[/tex]

Then:

[tex]A +B = 90[/tex]

Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]

[tex]1.5B + B = 90[/tex]

[tex]2.5B = 90[/tex]

Solve for B

[tex]B = \frac{90}{2.5}[/tex]

[tex]B = 36[/tex]

Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]

[tex]A = 1.5 * 36[/tex]

[tex]A = 54[/tex]

Step-by-step explanation:

Answer:

[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = 6 ÷ - 2 = - 18 ÷ 6 = 54 ÷ - 18 = - 3

This indicates the sequence is geometric with explicit formula

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = - 3 , then

[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]

Answer:

x = 135

Step-by-step explanation:

(100 + 121 + 105 + 113 + 108 + x) /6 = 112

547 + x = 112 × 6

547 + x = 672

x = 672 - 547

x = 135
