The ratio of circumference and diameter is equivalent to the parameter pi, which is 3.142

<h3>Area of Plain Shape(Circle)</h3>

Given Data

Diameter of small wheel = 7 inches

Circumference = 22 inches

Hence the expression for the ratio of circumference to diameter of the circle as decimal is given as

Ratio = 22/7

Ratio = 3.142

Upon studying low bids for shipping contracts, a microcomputer manufacturing company finds that intrastate contracts have low bi
Elena-2011 [213]

Answer:

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:

P(X < x) = \frac{x - a}{b - a}

Uniformly distributed between 22 and 29, in units of thousands of dollars.

This means that a = 22, b = 29.

(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.

This is P(X < 25). So

P(X < 25) = \frac{25 - 22}{29 - 22} = 0.4286

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

What is the value of x?
Andrei [34K]

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

x=2
