Answer:

= -89x + 227 =

Step-by-step explanation:

The value of x in the circle is 1.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

if a tangent and a chord are drawn from a point outside a circle, and the point of intersection of the tangent and the circle is labeled as point P, then the length of the tangent squared is equal to the product of the lengths of the two segments of the chord:

Now,

From the figure,

(2x - 9)² = 27 (2x + 2)

We can start by simplifying the left-hand side of the equation:

(2x - 9)² = 27 (2x + 2)

4x² - 36x + 81 = 54x + 54

Now we can move all the terms to one side and simplify:

4x² - 90x + 27 = 0

Next, we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

where a = 4, b = -90, and c = 27.

Plugging in the values:

x = (-(-90) ± √((-90)² - 4(4)(27))) / 2(4)

x = (90 ± √(8100 - 432)) / 8

x = (90 ± √(7668)) / 8

x = (90 ± √(447)) / 8

x ≈ 11.16 or x ≈ 1.09

Rounding to a whole number.

x = 1

Therefore,

The value of x in the circle is 1.

Step-by-step explanation:

Answer:

No, 0.85 is greater.

Step-by-step explanation:

Imagine a number line, with one at the end and 0.1 at the other end. With .85, It would be closer to one, with 0.6 being behind 0.85. The only other reason that 0.6 is greater than 0.85 is if they are converted to fractions.

Answer:

A gross refers to a group of 144 items (a dozen or a square dozen, 122). A great gross refers to a group of 1728 items (a dozen gross or a cubic dozen, 123). A small gross or a great hundred refers to a group of 120 items (ten dozen, 10×12).

If you are comparing a*b=4*3, a = 4 and b = 3.

This would mean that 2a = 8.

If a×b=2a=b, evaluate 4×3 , Based on the given equation, the result of 4 × 3 is 12.

To evaluate 4 × 3 using the given information, we substitute the values of a and b into the equation.

An equation is a mathematical statement that shows the equality of two expressions or quantities. It consists of an equal sign (=) placed between the two sides of the equation. The expressions on each side of the equal sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.

Equations are used to represent relationships and solve for unknown values. They can involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal is to find the value or values of the variable(s) that make the equation true.

Given: a × b = 2a = b

Let's assign a = 4 and b = 3:

4 × 3 = 2(4) = 3

Simplifying the equation:

12 = 8 = 3

Therefore, based on the given equation, the result of 4 × 3 is 12.

Answer:

After 12 years Bob will have $ 4,508.80 in his account.

Step-by-step explanation:

Given that Bob wants to invest his $ 3000 in an account that gets 3.4% interest rate compounded monthly, to determine how much money will he have after 12 years the following calculation must be performed:

3000 x (1 + 0.034 / 12) ^ 12x12 = X

3000 x (1 + 0.0028333) ^ 144 = X

3000 x 1.0028333 ^ 144 = X

3000 x 1.502932 = X

4,508.80 = X

Therefore, after 12 years Bob will have $ 4,508.80 in his account.

Answer:

  LA = 20π square units

  SA = 36π square units

  V = 16π cubic units

Step-by-step explanation:

The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:

  r² + 3² = 5²

  r = √(25 -9) = 4

__

The lateral area is given by the formula ...

  LA = πrs . . . . . where r is the radius and s is the slant height

  LA = π(4)(5)

  LA = 20π square units

__

The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.

  SA = πr² + LA

  SA = π(4²) +20π = 16π +20π

  SA = 36π square units

__

The volume is given by the formula ...

  V = 1/3πr²h

  V = 1/3π(4²)(3) = 16π

The volume is 16π cubic units.

We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %

Step-by-step explanation:

A pew research finds  that  23 %  ( μ ) of Americans use only cell phone

Sample Information

sample size   n  = 200

x₁  =  51     then   p₁  = 51/200   p₁  =  0,255

and  q₁  =  1  - p ₁    q₁  =  1  - 0,255    q₁  =  0,745

Sample big enough for the approximation of the binomial distribution to the normal distribution

p₁*n  = 0,255 * 200 = 51  > 5   and   q₁*n    = 0,745* 200 =  149 > 5

Test hypothesis

Null hypothesis                       H₀              p₁  = μ = 0,23

Alternative hypothesis           Hₐ              p₁  ≠  0,23

Is a two tail test. We choose CI = 95 %  then significance level is                    α = 0,05 %

α = 0,05 as is a two tail test   α/2  = 0,025

from z-table  z(c) = 1,96

To calculate  z(s) = ( x  -  μ ) /√p₁*q₁/n  

  z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200

z(s)  =  0,025 / 0,0308

z(s)  = 0,81

Comparing z(s)   and  z(c)

z(s) < z(c)      0,81 < 1,96

Then  z(s) is in the acceptance region: we accept H₀
