Answer:

False

Step-by-step explanation:

the area (A) of a rectangle is calculated as

A = length × breadth

  = (x + 5)(x - 5) ← expand factors using FOIL

  = x² - 5x + 5x - 25

 = x² - 25 ≠ x² - x - 15

The URS construction company has submitted two​ bids, one to build a large hotel in London and the other to build a commercial o
topjm [15]

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55

Hence, our required probability is 0.55.

PLEASE HELP ME QUICKLY!!!!

For each, you'll use the slope formula 
m = (y2-y1)/(x2-x1)

For function f, you'll use the two points (1,6) and (2,12) since x ranges from x = 1 to x = 2 for function f

The slope through these two points is 
m = (y2-y1)/(x2-x1)
m = (12-6)/(2-1)
m = 6/1
m = 6

-------------------------------------------

For function g, you'll use (2,4) and (3,20)

The slope through these two points is
m = (y2-y1)/(x2-x1)
m = (20-4)/(3-2)
m = 16/1
m = 16

-------------------------------------------

For function h, you'll use (0,-6) and (2,-18). The y coordinates can be found by plugging in x = 0 and x = 2 respectively into h(x)

The slope through these two points is
m = (y2-y1)/(x2-x1)
m = (-18-(-6))/(2-0)
m = (-18+6)/(2-0)
m = (-12)/(2)
m = -6

-------------------------------------------

The order from left to right is: h, f, g

How do I make the table? With what numbers?
zaharov [31]
The numbers they are looking for are numbers that are simple but made up. For example, start with 0. Plug 0 in for x, so the corresponding value of y is 10. For a second value, you could do 2. When x=2, y=11, etc. So essentially, put in some simple numbers for x, and solve for y. :)
