Answer:
8n + 5 = 69
And that number is 8, because 8•8+5=69
Step-by-step explanation:
"eight times a number and five is sixty-nine" in this statement the words "a number" is the number we dont know and so we use a variable for it. I put n, but you could have used x or a or any variable. The "and five" indicates adding. The "is" indicates equals.
(4y³ + 4y²+8)(6y - 4)
Simplify.
24y⁴ - 16y³ + 24y³ - 16y² + 48y - 32
Add like terms.
24y⁴ + (-16y³ + 24y³) -16y² + 48 - 32
Simplify.
24y⁴ + 8y³ - 16y³ + 16

The chance of rolling a number greater than 4 (a 5 and 6) is 2/6 = 1/3 after simplification. The probability it WON'T happen is 1 - 1/3 = 2/3.
The ratio of against to for is 2/3:1/3
You can further simplify this ratio by multiplying each side by 3 and yielding
2:1.
The chance of it not happening is twice as likely as it is to roll a number greater than 4
Answer:
14.4 to 1 dec. place.
Step-by-step explanation:
By Pythagoras:
17^2 = 9^2 + x^2
x^2 = 17^2 - 9^2
x^2 = 208
x = sqrt 208
x = 14.42.
