Answer:
v=2-2root7, v=2+2root7
Step-by-step explanation:
-2v+8(1+2v)=-90
-2-4v^2+8+16v=-90
6-4v^2+16v=-90
-4v^2+16v=-96
v=2-2root7, v=2+2root7

Well, 35/3 is simple, but 3 doesnt do into 35 so you might have gotten a long number, not big. But the answer is 11.66... or 11.6 repeating.
Answer:
Each section below
Step-by-step explanation:
(a) Add all frequencies together = 200, then add 1 and divide by 2 = 100.5, lastly you need to add each frequency until you find the interval that contains the 100th and 101st height.
23+47 = 70
70+45 = 115 -> so the answer is 10<h<u><</u>13
(b) Step 1: find the midpoint of each interval (upper limit+lower limit then divide by 2)
(2+6)/2 = 4
(6+10)/2 = 8
(10+13)/2 = 11.5
(13+17)/2 = 15
(17+19)/2 = 18
(19+20)/2 = 19.5
Step 2: multiply the midpoint of each interval with it's frequency
4*23 = 92
8*47 = 376
11.5*45 = 517.5
15*38 = 570
18*32 = 576
19.5*15 = 292.5
Step 3: add all of the above and divide it by the total frequency
92+376+517.5+570+576+292.5 = 2424
2424/200 = 12.12 (this is your answer to part b)
Hope this helped :)
Based on the number line, 144 ounces is equivalent to 144 ounces.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
From the number line:
6 pounds = 96 ounces
Hence:
9 pounds = 9 pounds * 96 ounces per 6 pounds = 144 ounces
Based on the number line, 144 ounces is equivalent to 144 ounces.
